+	(g77version.o): New rule to compile g77 version info.
+	(g77$(exeext)): Depend on and link in g77version.o.
+	* g77spec.c: Rewrite to be more like 0.5.22 version
+	of g77.c, making filtering of command line smarter
+	so mixed Fortran and C (etc.) can be compiled, verbose
+	version info can be obtained, etc.
+	* lang-specs.h (f77-version): New "language" to support
+	"g77 -v" command under new gcc 2.8 regime.
+	* lex.c (ffelex_file_fixed): If -fnull-version, just

+	* top.c, top.h: Support -fnull-version.
+
+	* lang-specs.h: Use "%O" instead of OO macro to specify
+	object extension.  Remove old stringizing cruft.
+
+	* Make-lang.in (g77.c, g77spec.o, g77.o, g77$(exeext),
+	g77-cross$(exeext), f771,
+	$(srcdir)/f/g77.info, $(srcdir)/f/g77.dvi,
+	$(srcdir)/f/intdoc.texi,
+	f77.install-common, f77.install-info, f77.install-man,
+	f77.uninstall, $(G77STAGESTUFF), f77.stage1, f77.stage2,
+	f77.stage3, f77.stage4, f77.distdir): Don't do anything
+	unless user specified "f77" or "F77" in $LANGUAGES either
+	during configuration or explicitly.  For convenience of
+	various tests and to work around lack of the assignment
+	"LANGUAGES=$(BOOT_LANGUAGES)" in the "make stage1" command
+	of "make bootstrap" in gcc, use a touch file named "lang-f77"
+	to communicate whether this is the case.
+
+	* Make-lang.in (F77_FLAGS_TO_PASS): Delete this macro,
+	replace with minimal expansion of its former self in
+	each of the two instances where it was used.
+
+	* Makefile.in (HOST_CC): Delete this definition.
+
+	* com.c (index, rindex): Delete these declarations.
+
+	* proj.h: (isascii): Delete this.

+	normalize and simplify g77/libg2c build process:
+	* Make-lang.in: Remove all support for overwriting
+	/usr/bin/f77 etc., or whatever the actual names are
+	via $(prefix) and $(local_prefix).  (g++ overwrites
+	/usr/bin/c++, but then it's often the only C++ compiler
+	on the system; f77 often exists on systems that are
+	installing g77.)
+	(f77.realclean): Remove obsolete target.
+	(g77.c, g77$(exeext)): Minor changes to look more like g++'s
+	stuff.
+	(f771): Now built with srcdir=gcc/f, not srcdir=gcc, to be
+	more like g++ and such.
+	(f/Makefile): Removed, as g++ doesn't need this rule.
+	(f77.install-common): No longer install f77, etc.
+	(f77.install-man): No longer install f77.1.
+	(f77.uninstall): No longer uninstall f77, f77.1, etc.
+	(f77.stage1, f77.stage2, f77.stage3, f77.stage4): Do work
+	only if "f77" appears in $(LANGUAGES).
+	(Note: gcc's Makefile.in's bootstrap target should set
+	LANGUAGES=$(BOOT_LANGUAGES) when making the stage1 target.)
+	* Makefile.in: Update vis-a-vis gcc/cp/Makefile.in.
+	(none): Remove.
+	(g77-only): Relocate.
+	(all.indirect, f771, *.o): Now assumes current directory
+	is this dir (gcc/f), not the parent directory.
+	(TAGS): Remove "echo 'parse.y,0'  >> TAGS ;" line.
+	* config-lang.in: Delete commented-out code.
+	Fix stagestuff definition.  Add more stuff to
+	diff_excludes definition.  Don't create any directories.
+	Set outputs to f/Makefile, to get variable substition
+	to happen (what does that really do, anyway?!).
+	* g77spec.c: Rename libf2c to libg2c.
+
+	* com.h: Remove all of the gcc back-end decls,
+	since egcs should have all of them correct.
+
+	* com.c: Include "proj.h" before anything else,
+	as that's how things are supposed to work.
+	* ste.c: Ditto.
+
+	* bad.c: Include "flags.j" here, since some diagnostics
+	check flag_pedantic_errors.
+
+	* Makefile.in (f/*.o): Rebuild dependencies via
+	deps-kinda.
+
+	* output.j: New source file.
+	* Make-lang.in (F77_SRCS): Update accordingly.
+	* Makefile.in (OUTPUT_H): Ditto.

+	* com.c: Include "output.j" here.
+	* lex.c: Ditto.

+
+	* com.c (ffecom_expr_): Fix D**I and Z**I cases to
+	not convert (DOUBLE PRECISION) D and (DOUBLE COMPLEX) Z
+	to INTEGER.  (This is dead code here anyway.)
+
+Sat May 23 06:32:52 1998  Craig Burley  <burley@gnu.org>
+
+	* com.c (ffecom_finish_symbol_transform_): Don't transform
+	statement (nested) functions, to avoid gcc compiling them
+	and thus producing linker errors if they refer to undefined
+	external functions.  But warn if they're unused and -Wunused.
+	* bad.def (FFEBAD_SFUNC_UNUSED): New diagnostic.
+
+Wed May 20 12:12:55 1998  Craig Burley  <burley@gnu.org>
+
+	* Version 0.5.23 released.
+
+Tue May 19 14:52:41 1998  Craig Burley  <burley@gnu.org>

+	in accord with same-dated change to f/runtime.
+

+
+	* com.c (ffecom_convert_narrow_, ffecom_convert_widen_):

+	Also, if precision isn't changing, just return the expr.
+
+	* expr.c (ffeexpr_token_number_): Call
+	ffeexpr_make_float_const_ to make an integer.
+	(ffeexpr_make_float_const_): Handle making an integer.
+
+	* intrin.c (ffeintrin_init_0): Distinguish between

+	(f77.distclean): Delete removal of g77.c.
+
+Thu Apr 30 18:59:43 1998  Jim Wilson  <wilson@cygnus.com>
+
+	* Make-lang.in (g77.info, g77.dvi, BUGS, INSTALL, NEWS): Put -o

+	right at the beginning, so EXTERNAL FOO followed later
+	by SUBROUTINE FOO is not diagnosed.
+
+	Fix 970813-0.f:
+	* com-rt.def (FFECOM_gfrtALARM): Returns `integer', not
+	`void'.

+Sun Aug 17 03:32:44 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix up problems when virtual memory exhausted:
+	* malloc.c (malloc_new_): Use gcc's xmalloc(), so we

+
+	* com.c (ffecom_sym_transform_): Don't set

+	a VAR_DECL, which happens when var is in common!
+
+	* com.c (ffecom_expr_intrinsic_) (case FFEINTRIN_impALARM):
+	No need to test codegen_imp -- there's only one valid here.
+
+	* intrin.def (FFEINTRIN_impALARM): Specify `Status' argument
+	as write-only.
+
+Fri Aug  8 05:40:23 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Substantial changes to accommodate distinctions among
+	run-time routines that support intrinsics, and between
+	routines that compute and return the same type vs. those
+	that compute one type and return another (or `void'):
+	* com-rt.def: Specify new return type REAL_F2C_ instead
+	of many DOUBLE_, COMPLEX_F2C_ instead of COMPLEX_, and
+	so on.
+	Clear up the *BES* routines "once and for all".
+	* com.c: New return types.
+	(ffecom_convert_narrow_, ffecom_convert_widen_):
+	New functions that are "safe" variants of convert(),
+	to catch errors that ffecom_expr_intrinsic_() now
+	no longer catches.
+	(ffecom_arglist_expr_): Ensure arguments are not
+	converted to narrower types.
+	(ffecom_call_): Ensure return value is not converted
+	to a wider type.
+	(ffecom_char_args_): Use new ffeintrin_gfrt_direct()
+	routine.
+	(ffecom_expr_intrinsic_): Simplify how run-time
+	routine is selected (via `gfrt' only now; lose the
+	redundant `ix' variable).
+	Eliminate the `library' label; any code that doesn't
+	return directly just `break's out now with `gfrt'
+	set appropriately.
+	Set `gfrt' to default choice initially, either a
+	fast direct form or, if not available, a slower
+	indirect-callable form.
+	(ffecom_make_gfrt_): No longer need to do special
+	check for complex; it's built into the new return-type
+	regime.
+	(ffecom_ptr_to_expr): Use new ffeintrin_gfrt_indirect()
+	routine.
+	* intrin.c, intrin.h: `gfrt' field replaced with three fields,
+	so it is easier to provide faster direct-callable and
+	GNU-convention indirect-callable routines in the future.
+	DEFIMP macro adjusted accordingly, along with all its uses.
+	(ffeintrin_gfrt_direct): New function.
+	(ffeintrin_gfrt_indirect): Ditto.
+	(ffeintrin_is_actualarg): If `-fno-f2c' is in effect,
+	require a GNU-callable version of intrinsic instead of
+	an f2c-callable version, so indirect calling is still checked.
+	* intrin.def: Replace one GFRT field with the three new fields,
+	as appropriate for each DEFIMP intrinsic.
+
+	* com.c (ffecom_stabilize_aggregate_,
+	ffecom_convert_to_complex_): Make these `static'.
+
+Thu Aug  7 11:24:34 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Provide means for front end to determine actual
+	"standard" return type for an intrinsic if it is

+	ffecom_gfrt_kindtype): New functions.
+	(ffecom_gfrt_kind_type_): Replaced with new function.
+	All callers updated.
+	(ffecom_make_gfrt_): No longer need do anything
+	with kind type.
+
+	* intrin.c (ffeintrin_basictype, ffeintrin_kindtype):
+	Now returns correct type info for specific intrinsic
+	(based on type of run-time-library implementation).
+
+Wed Aug  6 23:08:46 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* global.c (ffeglobal_ref_progunit_): Don't reset
+	number of arguments just due to new type info,
+	so useful warnings can be issued.
+
+1997-08-06  Dave Love  <d.love@dl.ac.uk>
+
+	* intrin.def: Fix IDATE_vxt argument order.
+	* intdoc.h: Likewise.
+
+Thu Jul 31 22:22:03 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* global.c (ffeglobal_proc_ref_arg): If REF/DESCR
+	disagreement, DESCR is CHARACTER, and types disagree,
+	pretend the argsummary agrees so the message ends up
+	being about type disagreement.
+	(ffeglobal_proc_def_arg): Ditto.
+
+	* expr.c (ffeexpr_token_first_rhs_3_): Set info for LABTOK
+	to NONE of everything, to avoid misdiagnosing filewide
+	usage of alternate returns.
+
+Sun Jul 20 23:07:47 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_sym_transform_): If type gets set
+	to error_mark_node, just return that for transformed symbol.
+	(ffecom_member_phase2_): If type gets set to error_mark_node,
+	just return.
+	(ffecom_check_size_overflow_): Add `dummy' argument to
+	flag that type is for a dummy, update all callers.
+
+Sun Jul 13 17:40:53 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix 970712-1.f:
+	* where.c (ffewhere_set_from_track): If start point
+	is too large, just use initial start point.  0.6 should
+	fix all this properly.
+
+	Fix 970712-2.f:
+	* com.c (ffecom_sym_transform_): Preserve error_mark_node for type.
+	(ffecom_type_localvar_): Ditto.
+	(ffecom_sym_transform_): If type is error_mark_node,
+	don't error-check decl size, because back end responds by
+	setting that to an integer 0 instead of error_mark_node.
+	(ffecom_transform_common_): Same as earlier fix to _transform_
+	in that size is checked by dividing BITS_PER_UNIT instead of
+	multiplying.
+	(ffecom_transform_equiv_): Ditto.
+
+	Fix 970712-3.f:
+	* stb.c (ffestb_R10014_): Fix flaky fall-through in error
+	test for FFELEX_typeCONCAT by just replicating the code,
+	and do FFELEX_typeCOLONCOLON while at it.
+
+1997-07-07  Dave Love  <d.love@dl.ac.uk>
+
+	* intdoc.h: Add various missing pieces; correct GMTIME, LTIME

+	* com.c (ffecom_expr_intrinsic_): Add case for alarm.
+
+Thu Jun 26 04:19:40 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix 970302-3.f:
+	* com.c (ffecom_sym_transform_): For sanity-check compare
+	of gbe size of local variable to g77 expectation,
+	use varasm.c/assemble_variable technique of dividing
+	BITS_PER_UNIT out of gbe info instead of multiplying
+	g77 info up, to avoid crash when size in bytes is very
+	large, and overflows an `int' or similar when multiplied.
+
+	Fix 970626-2.f:
+	* com.c (ffecom_finish_symbol_transform_): Don't bother
+	transforming a dummy argument, to avoid a crash.
+	* ste.c (ffeste_R1227): Don't return a value if the
+	result decl, or its type, is error_mark_node.
+
+	Fix 970626-4.f:
+	* lex.c (ffelex_splice_tokens): `-fdollar-ok' is
+	irrelevant to whether a DOLLAR token should be made
+	from an initial character of `$'.
+
+	Fix 970626-6.f:
+	* stb.c (ffestb_do3_): DO iteration variable is an
+	lhs, not rhs, expression.
+
+	Fix 970626-7.f and 970626-8.f:
+	* expr.c (ffeexpr_cb_comma_i_1_): Set IMPDO expression
+	to have clean info, because undefined rank, for example,
+	caused crash on mangled source on UltraSPARC but not
+	on Alpha for a series of weird reasons.
+	(ffeexpr_cb_close_paren_): If not CLOSE_PAREN, push
+	opANY expression onto stack instead of attempting
+	to mimic what program might have wanted.
+	(ffeexpr_cb_close_paren_): Don't wrap opPAREN around
+	opIMPDO, just warn that it's gratuitous.
+	* bad.def (FFEBAD_IMPDO_PAREN): New warning.
+
+	Fix 970626-9.f:
+	* expr.c (ffeexpr_declare_parenthesized_): Must shut down
+	parsing in kindANY case, otherwise the parsing engine might
+	decide there's an ambiguity.
+	(ffeexpr_token_name_rhs_): Eliminate parentypeSUBROUTINE_
+	case, so we crash right away if it comes through.
+	* st.c, st.h, sta.c, sta.h (ffest_shutdown, ffesta_shutdown):
+	New functions.
+
+Tue Jun 24 19:47:29 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_check_size_overflow_): New function

+
+Mon Jun 23 01:09:28 1997  Craig Burley  <burley@gnu.ai.mit.edu>

+	* global.c (ffeglobal_proc_def_arg): Fix comparison
+	of argno to #args.
+	(ffeglobal_proc_ref_arg): Ditto.
+
+	* lang-options.h, top.c: Rename `-fdebug' to `-fxyzzy',
+	since it's an unsupported internals option and some
+	poor user might guess that it does something.
+
+	* bad.def: Make a warning for each filewide diagnostic.
+	Put all filewides together.
+	* com.c (ffecom_sym_transform_): Don't substitute
+	known global tree for global entities when `-fno-globals'.
+	* global.c (ffeglobal_new_progunit_): Don't produce
+	fatal diagnostics about globals when `-fno-globals'.
+	Instead, produce equivalent warning when `-Wglobals'.

+	(ffeglobal_ref_progunit_): Ditto.
+	* lang-options.h, top.c, top.h: New `-fno-globals' option.

+
+	* expr.c (ffeexpr_fulfill_call_): Set array variable
+	to avoid warning about uninitialized variable.
+
+	* Make-lang.in: Get rid of any setting of HOST_* macros,
+	since these will break gcc's build!

+	easier.
+
+Thu Jun 19 18:19:28 1997  Craig Burley  <burley@gnu.ai.mit.edu>

+	`*f771' from the `specs' file.

+
+	* storag.c (ffestorag_update_init, ffestorag_update_save):
+	Also update parent, in case equivalence processing

+
+	* intdoc.c: Add cross-reference to end of description

+	Implement new scheme to track intrinsic names vs. forms:
+	* intrin.c (ffeintrin_fulfill_generic),
+	(ffeintrin_fulfill_specific), (ffeintrin_is_intrinsic),
+	intrin.def: The documented name is now either in the
+	generic info or, if no generic, in the specific info.
+	For a generic, the specific info contains merely the
+	distinguishing form (usually "function" or "subroutine"),
+	used for diagnostics about ambiguous references and
+	in the documentation.
+
+	* intrin.def: Clean up formatting of DEFNAME block.
+	Convert many libU77 intrinsics into generics that
+	support both subroutine and function forms.
+	Put the function forms of side-effect routines into

+
+Mon Jun  2 00:37:53 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_init_0): Pointer type is now INTEGER(KIND=7),
+	not INTEGER(KIND=0), since we want to reserve KIND=0 for
+	future use.
+
+Thu May 29 14:30:33 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix bugs preventing CTIME(I*4) from working correctly:

+	args to intrinsic just as they would be in
+	ffecom_expr_intrinsic_.

+	from being recognized.

+
+	* intrin.def (FFEINTRIN_impCTIME): Accept `I*' expression
+	for STime instead of requiring `I2'.
+
+Tue May 20 16:14:40 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* symbol.c (ffesymbol_reference): All references to
+	standard intrinsics are considered explicit, so as
+	to avoid generating basically useless warnings.
+	* intrin.c, intrin.h (ffeintrin_is_standard): Returns TRUE
+	if intrinsic is standard.
+
+Sun May 18 21:14:59 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com-rt.def: Changed all external names of the
+	form `"\([a-z0-9]*\)_' to `"G77_\1_0"' so as to
+	allow any name valid as an intrinsic to be used
+	as such and as a user-defined external procedure
+	name or common block as well.

+
+	* expr.c (ffeexpr_cb_end_notloc_): For %VAL, %REF, and

+
+	* intrin.def (FFEINTRIN_defSIGNAL): Add optional `Status'

+	* global.h, global.c:
+	Replace ->init mechanism with ->tick mechanism.
+	Move other common-related members into a substructure of
+	a union, so the proc substructure can be introduced

+	Don't complain about ANY-ized globals; ANY-ize globals
+	once they're complained about, in any case where code
+	generation could become a problem.
+	Handle global entries that have NONE type (seen as
+	intrinsics), EXT type (seen as EXTERNAL), and so on.
+	Keep track of kind and type of externals, both via

+	Diagnose disagreements about kind or type of externals
+	(such as functions).
+	(ffeglobal_ref_intrinsic, ffeglobal_ref_progunit_): New

+	* stc.c (ffestc_R1207_item, ffestc_R1208_item,
+	ffestc_R1219, ffestc_R1226):
+	Call ffesymbol_reference, not ffesymbol_globalize.
+	* stu.c (ffestu_sym_end_transition,
+	ffestu_sym_exec_transition):
+	Call ffesymbol_reference, not ffesymbol_globalize.
+	* symbol.c (ffesymbol_globalize): Removed...
+	(ffesymbol_reference): ...to this new function,
+	which more generally registers references to symbols,
+	globalizes globals, and calls on the ffeglobal module
+	to check globals filewide.
+
+	* global.h, global.c: Rename some macros and functions
+	to more clearly distinguish common from other globals.
+	All callers changed.
+
+	* com.c (ffecom_sym_transform_): Trees describing
+	filewide globals must be allocated on permanent obstack.
+
+	* expr.c (ffeexpr_token_name_lhs_): Don't generate
+	gratuitous diagnostics for FFEINFO_whereANY case.
+
+Thu Apr 17 03:27:18 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* global.c: Add support for flagging intrinsic/global
+	confusion via warnings.
+	* bad.def (FFEBAD_INTRINSIC_EXPIMP,
+	FFEBAD_INTRINSIC_GLOBAL): New diagnostics.
+	* expr.c (ffeexpr_token_funsubstr_): Ditto.
+	(ffeexpr_sym_lhs_call_): Ditto.
+	(ffeexpr_paren_rhs_let_): Ditto.
+	* stc.c (ffestc_R1208_item): Ditto.
+
+Wed Apr 16 22:40:56 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* expr.c (ffeexpr_declare_parenthesized_): INCLUDE
+	context can't be an intrinsic invocation either.
+
+Fri Mar 28 10:43:28 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* expr.c (ffeexpr_token_arguments_): Make sure top of
+	exprstack is operand before dereferencing operand field.
+
+	* lex.c (ffelex_prepare_eos_): Fill up truncated
+	hollerith token, so crash on null ->text field doesn't
+	happen later.
+
+	* stb.c (ffestb_R10014_): If NAMES isn't recognized (or
+	the recognized part is followed in the token by a
+	non-digit), don't try and collect digits, as there
+	might be more than FFEWHERE_indexMAX letters to skip
+	past to do so -- and the code is diagnosed anyway.
+
+Thu Mar 27 00:02:48 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_sym_transform_): Force local
+	adjustable array onto stack.
+
+	* stc.c (ffestc_R547_item_object): Don't actually put
+	the symbol in COMMON if the symbol has already been
+	EQUIVALENCE'd to a different COMMON area.
+
+	* equiv.c (ffeequiv_add): Don't actually do anything
+	if there's a disagreement over which COMMON area is
+	involved.
+
+Tue Mar 25 03:35:19 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_transform_common_): If no explicit init
+	of COMMON area, don't actually init it even though
+	storage area suggests it.
+
+Mon Mar 24 12:10:08 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* lex.c (ffelex_image_char_): Avoid overflowing the
+	column counter itself, as well as the card image.
+
+	* where.c (ffewhere_line_new): Cast ffelex_line_length()
+	to (size_t) so 255 doesn't overflow to 0!
+
+	* stc.c (ffestc_labeldef_notloop_begin_): Don't gratuitously
+	terminate loop before processing statement, so block
+	doesn't disappear out from under EXIT/CYCLE processing.
+	(ffestc_labeldef_notloop_): Has old code from above
+	function, instead of just calling it.
+
+	* expr.c (ffeexpr_cb_comma_i_4_): Don't skip over
+	arbitrary token (such as EOS).
+
+	* com.c (ffecom_init_zero_): Handle RECORD_TYPE and
+	UNION_TYPE so -fno-zeros works with -femulated-complex.
+
+1997-03-12  Dave Love  <d.love@dl.ac.uk>
+
+	* intrin.def: New intrinsics INT2, INT8, CPU_TIME.  Fix AND, OR,
+ 	XOR.  [Integrated by burley, AND/OR/XOR already fixed, INT8
+	implementation changed/fixed.]
+
+Wed Mar 12 10:40:08 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in ($(srcdir)/f/intdoc.texi): Simplify rules
+	so building f/intdoc is not always necessary; remove
+	f/intdoc after running it if it is built.
+
+Tue Mar 11 23:42:00 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* intrin.def (FFEINTRIN_impAND, FFEINTRIN_impOR,
+	FFEINTRIN_impXOR): Use the IAND, IOR, and IEOR implementations
+	of these, instead of crashing in ffecom_expr_intrinsic_
+	or adding case labels there.
+
+Mon Mar 10 22:51:23 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* intdoc.c: Fix so any C compiler can compile this.
+
+Fri Feb 28 13:16:50 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Version 0.5.20 released.
+
+Fri Feb 28 01:45:25 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in (RUNTIMESTAGESTUFF, LIBU77STAGESTUFF):
+	Move some files incorrectly in the former to the latter,
+	and add another file or two to the latter.
+
+	New meanings for (KIND=n), and new denotations in the
+	little language describing intrinsics:
+	* com.c (ffecom_init_0): Assign new meanings.
+	* intdoc.c: Document new meanings.
+	Support the new denotations.
+	* intrin.c: Employ new meanings, mapping them to internal
+	values (which are the same as they ever were for now).
+	Support the new denotations.
+	* intrin.def: Switch DEFIMP table to the new denotations.
+
+	* intrin.c (ffeintrin_check_): Fix bug that was leaving
+	LOC() and %LOC() returning INTEGER*4 on systems where
+	it should return INTEGER*8.
+
+	* type.c: Canonicalize function definitions, for etags
+	and such.
+
+Wed Feb 26 20:43:03 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_init_0): Choose INTEGER(KIND=n) types,
+	where n is 2, 3, and 4, according to the new docs
+	instead of according to the old C correspondences
+	(which seem less useful at this point).
+
+	* equiv.c (ffeequiv_destroy_): New function.
+	(ffeequiv_layout_local_): Use this new function
+	whenever the laying out of a local equivalence chain
+	is aborted for any reason.
+	Otherwise ensure that symbols no longer reference
+	the stale ffeequiv entries that result when they
+	are killed off in this procedure.
+	Also, the rooted symbol is one that has storage,
+	it really is irrelevant whether it has an equiv entry
+	at this point (though the code to remove the equiv
+	entry was put in at the end, just in case).
+	(ffeequiv_kill): When doing internal checks, make
+	sure the victim isn't named by any symbols it points
+	to.  Not as complete a check as looking through the
+	entire symbol table (which does matter, since some
+	code in equiv.c used to remove symbols from the lists
+	for an ffeequiv victim but not remove that victim as the
+	symbol's equiv info), but this check did find some
+	real bugs in the code (that were fixed).
+
+Mon Feb 24 16:42:13 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_expr_intrinsic_): Fix a couple of
+	warnings about uninitialized variables.
+	* intrin.c (ffeintrin_check_): Ditto, but there were
+	a couple of _real_ uninitialized-variable _bugs_ here!
+	(ffeintrin_fulfill_specific): Ditto, no real bug here.
+
+Sun Feb 23 15:01:20 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Clean up diagnostics (especially about intrinsics):
+	* bad.def (FFEBAD_UNIMPL_STMT): Remove.
+	(FFEBAD_INTRINSIC_*, FFEBAD_NEED_INTRINSIC): Clean these
+	up so they're friendlier.
+	(FFEBAD_INTRINSIC_CMPAMBIG): New.
+	* intrin.c (ffeintrin_fulfill_generic,
+	ffeintrin_fulfill_specific, ffeintrin_is_intrinsic):
+	Always choose
+	generic or specific name text (which is for doc purposes
+	anyway) over implementation name text (which is for
+	internal use).
+	* intrin.def: Use more descriptive name texts for generics
+	and specifics in cases where the names themselves are not
+	enough (e.g. IDATE, which has two forms).
+
+	Fix some intrinsic mappings:
+	* intrin.def (FFEINTRIN_specIDINT, FFEINTRIN_specAND,
+	FFEINTRIN_specDFLOAT, FFEINTRIN_specDREAL, FFEINTRIN_specOR,
+	FFEINTRIN_specXOR): Now have their own implementations,
+	instead of borrowing from others.
+	(FFEINTRIN_specAJMAX0, FFEINTRIN_specAJMIN0, FFEINTRIN_specBJTEST,
+	FFEINTRIN_specDFLOTJ, FFEINTRIN_specFLOATJ, FFEINTRIN_specJIABS,
+	FFEINTRIN_specJIAND, FFEINTRIN_specJIBCLR, FFEINTRIN_specJIBITS,
+	FFEINTRIN_specJIBSET, FFEINTRIN_specJIDIM, FFEINTRIN_specJIDINT,
+	FFEINTRIN_specJIDNNT, FFEINTRIN_specJIEOR, FFEINTRIN_specJIFIX,
+	FFEINTRIN_specJINT, FFEINTRIN_specJIOR, FFEINTRIN_specJISHFT,
+	FFEINTRIN_specJISHFTC, FFEINTRIN_specJISIN, FFEINTRIN_specJMAX0,
+	FFEINTRIN_specJMAX1, FFEINTRIN_specJMIN0, FFEINTRIN_specJMIN1,
+	FFEINTRIN_specJMOD, FFEINTRIN_specJNINT, FFEINTRIN_specJNOT,):
+	Turn these implementations off, since it's not clear
+	just what types they expect in the context of portable Fortran.
+	(DFLOAT): Now in FVZ family, since f2c supports them
+
+	Support intrinsic inquiry functions (BIT_SIZE, LEN):
+	* intrin.c: Allow `i' in <arg_extra>.
+	* intrin.def (FFEINTRIN_impBIT_SIZE, FFEINTRIN_impLEN):
+	Mark args with `i'.
+
+Sat Feb 22 13:34:09 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Only warn, don't error, for reference to unimplemented
+	intrinsic:
+	* bad.def (FFEBAD_INTRINSIC_UNIMPLW): Warning version
+	of _UNIMPL.
+	* intrin.c (ffeintrin_is_intrinsic): Use new warning
+	version of _UNIMPL (FFEBAD_INTRINSIC_UNIMPLW).
+
+	Complain about REAL(Z) and AIMAG(Z) (Z is DOUBLE COMPLEX):
+	* bad.def (FFEBAD_INTRINSIC_CMPAMBIG): New diagnostic.
+	* expr.c: Needed #include "intrin.h" anyway.
+	(ffeexpr_token_intrincheck_): New function handles delayed
+	diagnostic for "REAL(REAL(expr)" if next token isn't ")".
+	(ffeexpr_token_arguments_): Do most of the actual checking here.
+	* intrin.h, intrin.c (ffeintrin_fulfill_specific): New
+	argument, check_intrin, to tell caller that intrin is REAL(Z)
+	or AIMAG(Z).  All callers updated, mostly to pass NULL in
+	for this.
+	(ffeintrin_check_): Also has new arg check_intrin for same
+	purpose.  All callers updated the same way.
+	* intrin.def (FFEINTRIN_impAIMAG): Change return type
+	from "R0" to "RC", to accommodate f2c (and perhaps other
+	non-F90 F77 compilers).
+	* top.h, top.c: New option -fugly-complex.
+
+	New GNU intrinsics REALPART, IMAGPART, and COMPLEX:
+	* com.c (ffecom_expr_intrinsic_): Implement impCOMPLEX
+	and impREALPART here.  (specIMAGPART => specAIMAG.)
+	* intrin.def: Add the intrinsics here.
+
+	Rename implementations of VXTIDATE and VXTTIME to IDATEVXT
+	and TIMEVXT, so they sort more consistently:
+	* com.c (ffecom_expr_intrinsic_):
+	* intrin.def:
+
+	Delete intrinsic group `dcp', add `gnu', etc.:
+	* intrin.c (ffeintrin_state_family): FFEINTRIN_familyGNU
+	replaces FFEINTRIN_familyDCP, and gets state from `gnu'
+	group.
+	Get rid of FFEINTRIN_familyF2Z, nobody needs it.
+	Move FFEINTRIN_specDCMPLX from DCP family to FVZ family,
+	as f2c has it.
+	Move FFEINTRIN_specDFLOAT from F2C family to FVZ family.
+	(FFEINTRIN_specZABS, FFEINTRIN_specZCOS, FFEINTRIN_specZEXP,
+	FFEINTRIN_specZLOG, FFEINTRIN_specZSIN, FFEINTRIN_specZSQRT):
+	Move these from F2Z family to F2C family.
+	* intrin.h (FFEINTRIN_familyF2Z, FFEINTRIN_familyDCP): Remove.
+	(FFEINTRIN_familyGNU): Add.
+	* top.h, top.c: Replace `dcp' with `gnu'.
+
+	* com.c (ffecom_expr_intrinsic_): Clean up by collecting
+	simple conversions into one nice, conceptual place.
+	Fix up some intrinsic subroutines (MVBITS, KILL, UMASK) to
+	properly push and pop call temps, to avoid wasting temp
+	registers.
+
+	* g77.c (doit): Toon says variables should be defined
+	before being referenced.  Spoilsport.
+
+	* intrin.c (ffeintrin_check_): Now Dave's worried about
+	warnings about uninitialized variables.  Okay, so for
+	basic return values 'g' and 's', they _were_
+	uninitialized -- is determinism really _that_ useful?
+
+	* intrin.def (FFEINTRIN_impFGETC): Fix STATUS argument
+	so that it is INTENT(OUT) instead of INTENT(IN).
+
+1997-02-21  Dave Love  <d.love@dl.ac.uk>
+
+	* intrin.def, com.c: Support Sun-type `short' and `long'
+	intrinsics.  Perhaps should also do Microcruft-style `int2'.
+
+Thu Feb 20 15:16:53 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_expr_intrinsic_): Clean up indentation.
+	Support SECONDSUBR intrinsic implementation.
+	Rename SECOND to SECONDFUNC for direct support via library.
+
+	* g77.c: Fix to return proper status value to shell,
+	by obtaining it from processes it spawns.
+
+	* intdoc.c: Fix minor typo.
+
+	* intrin.def: Turn SECOND into generic that maps into
+	function and subroutine forms.
+
+	* intrin.def: Make FLOAT and SNGL into specific intrinsics.
+
+	* intrin.def, intrin.h: Change the way DEFGEN and DEFSPEC
+	macros work, to save on verbage.
+
+Mon Feb 17 02:08:04 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	New subsystem to automatically generate documentation
+	on intrinsics:
+	* Make-lang.in ($(srcdir)/f/g77.info,
+	$(srcdir)/f/g77.dvi): Move g77 doc rules around.
+	Add to g77 doc rules the new subsystem.
+	(f77.mostlyclean, f77.maintainer-clean): Also clean up
+	after new doc subsystem.
+	* intdoc.c, intdoc.h: New doc subsystem code.
+	* intrin.h [FFEINTRIN_DOC]: When 1, don't pull in
+	stuff not needed by doc subsystem.
+
+	Improve on intrinsics mechanism to both be more
+	self-documenting and to catch more user errors:
+	* intrin.c (ffeintrin_check_): Recognize new arg-len
+	and arg-rank information, and check it.
+	Move goto and signal indicators to the basic type.
+	Permit reference to arbitrary argument number, not
+	just first argument (for BESJN and BESYN).
+	(ffeintrin_init_0): Check and accept new notations.
+	* intrin.c, intrin.def: Value in COL now identifies
+	arguments starting with number 0 being the first.
+
+	Some minor intrinsics cleanups (resulting from doc work):
+	* com.c (ffecom_expr_intrinsic_): Implement FLUSH
+	directly once again, handle its optional argument,
+	so it need not be a generic (awkward to handle in docs).
+	* intrin.def (BESJ0, BESJ1, BESJN, BESY0, BESY1, BESYN,
+	CHDIR, CHMOD, CTIME, DBESJ0, DBESJ1, DBESJN, DBESY0,
+	DBESY1, DBESYN, DDIM, ETIME, FGETC, FNUM, FPUTC, FSTAT,
+	GERROR, GETCWD, GETGID, GETLOG, GETPID, GETUID, GMTIME,
+	HOSTNM, IDATE, IERRNO, IIDINT, IRAND, ISATTY, ITIME, JIDINT,
+	LNBLNK, LSTAT, LTIME, MCLOCK, PERROR, SRAND, SYMLNK, TTYNAM,
+	UMASK): Change capitalization of initcaps (official) name
+	to be consistent with Burley's somewhat arbitrary rules.
+	(BESJN, BESYN): These have return arguments of same type
+	as their _second_ argument.
+	(FLUSH): Now a specific, not generic, intrinsic, with one
+	optional argument.
+	(FLUSH1): Eliminated.
+	Add arg-len and arg-rank info to several intrinsics.
+	(ITIME): Change argument type from REAL to INTEGER.
+
+Tue Feb 11 14:04:42 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in (f771): Invocation of Makefile now done
+	with $(srcdir)=gcc to go along with $(VPATH)=gcc.
+	($(srcdir)/f/runtime/configure,
+	$(srcdir)/f/runtime/libU77/configure): Break these out
+	so spurious triggers of this rule don't happen (as when
+	configure.in is more recent than libU77/configure).
+	(f77.rebuilt): Distinguish source versus build files,
+	so this target can be invoked from build directory and
+	still work.
+	* Makefile.in: This now expects $(srcdir) to be the gcc
+	source directory, not gcc/f, to agree with $(VPATH).
+	Accordingly, $(INCLUDES) has been fixed, various cruft
+	removed, the removal of f771 has been fixed to remove
+	the _real_ f771 (not the one in gcc's parent directory),
+	and so on.
+
+	* lex.c: Part of ffelex_finish_statement_() now done
+	by new function ffelex_prepare_eos_(), so that, in one
+	popular case, the EOS can be prepared while the pointer
+	is at the end of the non-continued line instead of the
+	end of the line that marks no continuation.  This improves
+	the appearance of diagnostics substantially.
+
+Mon Feb 10 12:44:06 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in: runtime Makefile's, and include/f2c.h,
+	also depend on f/runtime/configure and f/runtime/libU77/configure.
+
+	Fix various libU77 routines:
+	* com-rt.def (FFECOM_gfrtCTIME, FFECOM_gfrtMCLOCK,
+	FFECOM_gfrtTIME): These now use INTEGER*8 for time values,
+	for compatibility with systems like Alpha.
+	(FFECOM_gfrtSYSTEM_CLOCK, FFECOM_gfrtTTYNAM): Delete incorrect
+	trailing underscore in routine names.
+	* intrin.c, intrin.def: Support INTEGER*8 return values and
+	arguments ('4').  Change FFEINTRIN_impCTIME, FFEINTRIN_impMCLOCK,
+	and FFEINTRIN_impTIME accordingly.
+	(ffeintrin_is_intrinsic): Don't give caller a clue about
+	form of intrinsic -- shouldn't be needed at this point.
+
+	Cope with generic intrinsics that are subroutines and functions:
+	* com.c (ffecom_finish_symbol_transform_, ffecom_expr_transform_):
+	Don't transform an intrinsic that is not known to be a subroutine
+	or a function.  (Maybe someday have to avoid transforming
+	any intrinsic with an undecided or unknown implementation.)
+	* expr.c (ffeexpr_declare_unadorned_,
+	ffeexpr_declare_parenthesized_): Ok to invoke generic
+	intrinsic that has at least one subroutine form as a
+	subroutine.
+	Ok to pass intrinsic as actual arg if it has a known specific
+	intrinsic form that is valid as actual arg.
+	(ffeexpr_declare_parenthesized_): An unknown kind of
+	intrinsic has a paren_type chosen based on context.
+	(ffeexpr_token_arguments_): Build funcref/subrref based
+	on context, not on kind of procedure being called.
+	* intrin.h, intrin.c (ffeintrin_is_intrinsic): Undo changes of
+	Tue Feb  4 23:12:04 1997 by me, change all callers to leave
+	intrinsics as FFEINFO_kindNONE at this point.  (Some callers
+	also had unused variables deleted as a result.)
+
+	Enable all intrinsic groups (especially f90 and vxt):
+	* target.h (FFETARGET_defaultSTATE_DCP, FFETARGET_defaultSTATE_F2C,
+	FFETARGET_defaultSTATE_F90, FFETARGET_defaultSTATE_MIL,
+	FFETARGET_defaultSTATE_UNIX, FFETARGET_defaultSTATE_VXT):
+	Delete these macros, let top.c set them directly.
+	* top.c (ffeintrinsic_state_dcp_, ffe_intrinsic_state_f2c_,
+	ffe_intrinsic_state_f90_, ffe_intrinsic_state_mil_,
+	ffe_intrinsic_state_unix_, ffe_intrinsic_state_vxt_):
+	Enable all these directly.
+
+Sat Feb  8 03:21:50 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* g77.c: Incorporate recent changes to ../gcc.c.
+	For version magic (e.g. `g77 -v'), instead of compiling
+	/dev/null, write, compile, run, and then delete a small
+	program that prints the version numbers of the three
+	components of libf2c (libF77, libI77, and libU77),
+	so we get this info with bug reports.
+	Also, this change reduces the chances of accidentally
+	linking to an old (complex-alias-problem) libf2c.
+	Fix `-L' so the argument is expected in `-Larg'.
+
+	* com.h (FFECOM_f2cLONGINT): For INTEGER*8 support in f2c.h,
+	dynamically determine proper type here, instead of
+	assuming `long long int' is correct.
+
+Tue Feb  4 23:12:04 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Add libU77 library from Dave Love <d.love@dl.ac.uk>:
+	* Make-lang.in (f77-runtime): Depend on new Makefile.
+	(f/runtime/libU77/Makefile): New rule.
+	Also configure libU77.
+	($(srcdir)/f/runtime/configure: Use Makefile.in,
+	so configuration doesn't have to have happened.
+	(f77.mostlyclean, f77.clean, f77.distclean,
+	f77.maintainer-clean): Some fixups here, but more work
+	needed.
+	(RUNTIMESTAGESTUFF): Add libU77's config.status.
+	(LIBU77STAGESTUFF, f77.stage1, f77.stage2, f77.stage3,
+	f77.stage4): New macro, appropriate uses added.
+	* com-rt.def: Add libU77 procedures.
+	* com.c (ffecom_f2c_ptr_to_integer_type_node,
+	ffecom_f2c_ptr_to_real_type_node): New type nodes.
+	(FFECOM_rttypeCHARACTER_): New type of run-time function.
+	(ffecom_char_args_): Handle CHARACTER*n intrinsics
+	where n != 1 here, instead of in ffecom_expr_intrinsic_.
+	(ffecom_expr_intrinsic_): New code to handle new
+	intrinsics.
+	In particular, change how FFEINTRIN_impFLUSH is handled.
+	(ffecom_make_gfrt_): Handle new type of run-time function.
+	(ffecom_init_0): Initialize new type nodes.
+	* config-lang.in: New libU77 directory.
+	* intrin.h, intrin.c (ffeintrin_is_intrinsic): Handle
+	potential generic for subroutine _and_ function
+	specifics via two new arguments.  All callers changed.
+	Properly ignore deleted/disabled intrinsics in resolving
+	generics.
+	(ffeintrin_check_, ffeintrin_init_0): Handle CHARACTER intrinsics of (*)
+	length.
+	* intrin.def: Permission granted by FSF to place this in
+	public domain, which will allow it to serve as source
+	for both g77 program and its documentation.
+	Add libU77 intrinsics.
+	(FLUSH): Now a generic, not specific, intrinsic.
+	(DEFIMP): Now support return modifier for CHARACTER intrinsics.
+
+	* com-rt.def (FFECOM_gfrtDIM, FFECOM_gfrtERF,
+	FFECOM_gfrtERFC, FFECOM_gfrtEXP, FFECOM_gfrtSIGN,
+	FFECOM_gfrtSIN, FFECOM_gfrtSINH, FFECOM_gfrtTAN,
+	FFECOM_gfrtTANH, FFECOM_gfrtPOW_RI): Change "&r" to "&f".
+
+Sat Feb  1 12:15:09 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Version 0.5.19.1 released.
+
+	* com.c (ffecom_expr_, ffecom_expr_intrinsic_,
+	ffecom_tree_divide_): FFECOM_gfrtPOW_ZI,

+
+	* com.c (ffecom_init_0): Do internal checks only if
+	-fset-g77-defaults not specified.
+
+	Fix %LOC(), LOC() to return sufficiently wide type:
+	* com.h, com.c (ffecom_pointer_kind_, ffecom_label_kind_,
+	ffecom_pointer_kind(), ffecom_label_kind()): New globals
+	and accessor macros hold kind for integer pointers on target
+	machine.
+	(ffecom_init_0): Determine narrowest INTEGER type that
+	can hold a pointer (usually INTEGER*4 or INTEGER*8),
+	store it in ffecom_pointer_kind_, etc.
+	* expr.c (ffeexpr_cb_end_loc_): Use right type for %LOC().
+	* intrin.c (ffeintrin_check_, ffeintrin_init_0): Support
+	new 'p' kind for type of intrinsic.
+	* intrin.def (FFEINTRIN_impLOC): Returns "Ip" instead of "I1",
+	so LOC() type is correct for target machine.
+
+	Support -fugly-assign:
+	* lang-options.h, top.h, top.c (ffe_decode_option):
+	Accept -fugly-assign and -fno-ugly-assign.
+	* com.c (ffecom_expr_): Handle -fugly-assign.
+	* expr.c (ffeexpr_finished_): Check right type for ASSIGN
+	contexts.
+
+Fri Jan 31 14:30:00 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Remove last vestiges of -fvxt-not-f90:
+	* stb.c (ffestb_R10012_, ffestb_R10014_, ffestb_V0201_):
+	top.c, top.h:
+
+Fri Jan 31 02:13:54 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* top.c (ffe_decode_option): Warn if -fugly is specified,
+	it'll go away soon.
+
+	* symbol.h: No need to #include "bad.h".
+
+	Reorganize features from -fvxt-not-f90 to -fvxt:
+	* lang-options.h, top.h, top.c:
+	Accept -fvxt and -fno-vxt, but not -fvxt-not-f90 or -ff90-not-vxt.
+	Warn if the latter two are used.
+	* expr.c (ffeexpr_nil_rhs_): Double-quote means octal constant.
+	(ffeexpr_token_rhs_): Double-quote means octal constant.
+	* target.h (FFETARGET_defaultIS_VXT_NOT_90): Delete macro
+	definition, no longer needed.
+
+	Make some -ff90 features the default:
+	* data.c (ffedata_value): DATA implies SAVE.

+
+	Fix up some more #error directives by quoting their text:

+
+Sat Jan 18 18:22:09 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* g77.c (lookup_option, main): Recognize `-Xlinker',
+	`-Wl,', `-l', `-L', `--library-directory', `-o',
+	`--output'.
+	(lookup_option): Don't depend on SWITCH_TAKES_ARG
+	being correct, it might or might not have `-x' in
+	it depending on host.
+	Return NULL argument if it would be an empty string.
+	(main): If no input files (by gcc.c's definition)
+	but `-o' or `--output' specified, produce diagnostic
+	to avoid overwriting output via gcc.
+	Recognize C++ `+e' options.
+	Treat -L as another non-magical option (like -B).
+	Don't append_arg `-x' twice.
+
+Fri Jan 10 23:36:00 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* top.c [BUILT_FOR_270] (ffe_decode_option): Make

+
+Fri Jan 10 07:42:27 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Enable inlining of previously-compiled program units:
+	* com.c (ffecom_do_entry_, ffecom_start_progunit_):
+	Register new public function in ffeglobal database.
+	(ffecom_sym_transform_): Any GLOBAL or potentially GLOBAL
+	symbol should be looked up in ffeglobal database and
+	that tree node used, if found.  That way, gcc knows
+	the references are to those earlier definitions, so it
+	can emit shorter branches/calls, inline, etc.
+	(ffecom_transform_common_): Minor change for clarity.
+	* expr.c (ffeexpr_sym-lhs_call_, ffeexpr_sym_lhs_extfunc_,
+	ffeexpr_sym_rhs_actualarg_, ffeexpr_paren_rhs_let_,
+	ffeexpr_token_funsubstr_): Globalize symbol as needed.

+
+	* ste.c (ffeste_R809): Produce a diagnostic for SELECT CASE
+	on CHARACTER type, instead of crashing.
+
+Thu Jan  9 00:52:45 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* stc.c (ffestc_order_entry_, ffestc_order_format_,
+	ffestc_R1226): Allow ENTRY and FORMAT before IMPLICIT
+	NONE, by having them transition only to state 1 instead
+	of state 2 (which is disallowed by IMPLICIT NONE).
+
+Mon Jan  6 22:44:53 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix AXP bug found by Rick Niles (961201-1.f):
+	* com.c (ffecom_init_0): Undo my 1996-05-14 change, as
+	it is incorrect and prevented easily finding this bug.
+	* target.h [__alpha__] (ffetargetReal1, ffetargetReal2):
+	Use int	instead of long.
+	(ffetarget_cvt_r1_to_rv_, ffetarget_cvt_rv_to_r1_,
+	ffetarget_cvt_r2_to_rv_, ffetarget_cvt_rv_to_r2_):
+	New functions that intercede for callers of
+	REAL_VALUE_(TO|UNTO)_TARGET_(SINGLE|DOUBLE).
+	All callers changed, and damaging casts to (long *) removed.

+Sun Jan  5 03:26:11 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in (g77, g77-cross): Depend on both g77.c and

+
+	Better design for -fugly-assumed:
+	* stc.c (ffestc_R501_item, ffestc_R524_item,
+	ffestc_R547_item_object): Pass new is_ugly_assumed flag.
+	* stt.c, stt.h (ffestt_dimlist_as_expr,
+	ffestt_dimlist_type): New is_ugly_assumed flag now
+	controls whether "1" is treated as "*".
+	Don't treat "2-1" or other collapsed constants as "*".
+
+Sat Jan  4 15:26:22 1997  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* stb.c (ffestb_R10012_): Don't confirm on FORMAT(A,)
+	or even FORMAT(A,,B), as R1229 only warns about the
+	former currently, and this seems reasonable.
+
+	Improvements to diagnostics:
+	* sta.c (ffesta_second_): Don't add any ffestb parsers
+	unless they're specifically called for.
+	Set up ffesta_tokens[0] before calling ffestc_exec_transition,
+	else stale info might get used.
+	(ffesta_save_): Do a better job picking which parser to run
+	after running all parsers with no confirmed possibles.
+	(FFESTA_maxPOSSIBLES_): Decrease from 100 now that so few
+	possibles are ever on the list at a given time.
+	(struct _ffesta_possible): Add named attribute.
+	(ffesta_add_possible_exec_, ffesta_add_possible_nonexec_):
+	Make these into macros that call a single function that now
+	sets the named attribute.
+	(ffesta_add_possible_unnamed_exec_,
+	ffeseta_add_possible_unnamed_nonexec_): New macros.
+	(ffesta_second_): Designate unnamed possibles as
+	appropriate.
+	* stb.c (ffestb_R1229, ffestb_R12291_): Use more general
+	diagnostic, so things like "POINTER (FOO, BAR)" are
+	diagnosed as unrecognized statements, not invalid statement
+	functions.
+	* stb.h, stb.c (ffestb_unimplemented): Remove function.
+
+1996-12-30  Dave Love  <d.love@dl.ac.uk>

+	(ffecom_expr_intrinsic_): Many news cases for libU77 intrinsics.
+
+	* com-rt.def: New definitions for libU77.
+	* intrin.def: Likewise.  Also correct ftell arg spec.
+
+	* Makefile.in (f/runtime/libU77/config.h): New target for com.c
+ 	dependency.
+	* Make-lang.in (f771): Depend on f/runtime/Makefile for the above.
+
+Sat Dec 28 12:28:29 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* stt.c (ffestt_dimlist_type): 	Treat ([...,]1) in dimlist
+	as ([...,]*) if -fugly-assumed, so assumed-size array
+	detected early enough.
+
+Thu Dec 19 14:01:57 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* target.h (FFETARGET_REAL_VALUE_FROM_INT_): Conditionalize
+	definition on BUILT_FOR_280, not BUILT_WITH_280, since
+	the name of the macro was (properly) changed since 0.5.19.
+
+	Fix warnings/errors resulting from ffetargetOffset becoming
+	`long long int' instead of `unsigned long' as of 0.5.19,
+	while ffebitCount remains `unsigned long':
+	* bld.c (ffebld_constantarray_dump): Avoid warnings by
+	using loop var of appropriate type, and using casts.
+	* com.c (ffecom_expr_): Use right type for loop var.
+	(ffecom_sym_transform_, ffecom_transform_equiv_):
+	Cast to right type in assertions.
+	* data.c (ffedata_gather_, ffedata_value_): Cast to right
+	type in assertions and comparisons.
+
+Wed Dec 18 12:07:11 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Patch from Alexandre Oliva <oliva@dcc.unicamp.br>:

+	OFFSET_REF.
+	(ffecom_build_complex_constant_): Conditionalize calling
+	sequence for build_complex.
+
+Sat Dec  7 07:15:17 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Version 0.5.19 released.
+
+Fri Dec  6 12:23:55 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* g77.c: Default to assuming "f77" is in $LANGUAGES, since
+	the LANGUAGE_F77 macro isn't defined by anyone anymore (but
+	might as well leave the no-f77 code in just in case).
+	* Make-lang.in (g77, g77-cross): Don't define LANGUAGE_F77
+	anymore.
+
+1996-12-06  Dave Love  <d.love@dl.ac.uk>
+
+	* Make-lang.in (g77, g77-cross): Revert to building `g77' or not
+	conditional on `f77' in LANGUAGES.
+
+Wed Dec  4 13:08:44 1996  Craig Burley  <burley@gnu.ai.mit.edu>

+	in case where "f77" is not in $LANGUAGES.
+
+	* lex.c (ffelex_image_char_, ffelex_file_fixed,
+	ffelex_file_free): Fixes to properly handle lines with
+	null character, and too-long lines as well.
+
+	* lex.c: Call ffebad_start_msg_lex instead of
+	ffebad_start_msg throughout.
+
+Sun Dec  1 21:19:55 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Fix-up for 1996-11-25 changes:
+	* com.c (ffecom_member_phase2_): Subtract out 0 offset for
+	elegance and consistency with EQUIVALENCE aggregates.
+	(ffecom_sym_transform_): Ditto for LOCAL/COMMON, and
+	ensure we get the same parent storage area.
+	* data.c (ffedata_gather_, ffedata_value_): Subtract out
+	aggregate offset.
+
+Wed Nov 27 13:55:57 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* proj.h: Quote the text of the #error message, to avoid
+	strange-looking diagnostics from non-gcc ANSI compilers.
+
+	* top.c: Make -fno-debug-kludge the default.
+
+Mon Nov 25 20:13:45 1996  Craig Burley  <burley@gnu.ai.mit.edu>

+	* bad.def (FFEBAD_EQUIV_MISMATCH): More detailed message.
+	* equiv.c (ffeequiv_layout_local_, ffeequiv_layout_cblock):
+	More details for FFEBAD_EQUIV_MISMATCH.
+
+	Fix problem with EQUIVALENCE handling:
+	* equiv.c (ffeequiv_layout_local_): Redesign algorithm --
+	old one was broken, resulting in rejection of good code.
+	(ffeequiv_offset_): Add argument, change callers.
+	Clean up the code, fix up the (probably unused) negative-value
+	case for SYMTER.
+	* com.c (ffecom_sym_transform_): For local EQUIVALENCE
+	member, subtract out aggregate offset (which is <= 0).
+
+Thu Nov 21 12:44:56 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Change type of ffetargetOffset from `unsigned long' to `long long':
+	* bld.c (ffebld_constantarray_dump): Change printf formats.
+	* storag.c (ffestorag_dump): Ditto.
+	* symbol.c (ffesymbol_report): Ditto.
+	* target.h (ffetargetOffset_f): Ditto and change type itself.
+
+	Handle situation where list of languages does not include f77:
+	* Make-lang.in: Define LANGUAGE_F77 to 1 only if `f77' is in
+	the $LANGUAGES macro for the build.
+	* g77.c: Compile to a (nearly) no-op program if LANGUAGE_F77
+	is not defined to 1.
+
+	Fixes to delay confirmation of READ, WRITE, and GOTO statements
+	so the corresponding assignments to same-named CHAR*(*) arrays
+	work:
+	* stb.c (ffestb_R90915_, ffestb_91014_): New functions.
+	(ffestb_goto3_, ffestb_goto5_): Move confirmation from 3 to 5

+	ffestb_R91012_, ffestb_R91013_): Use new functions, and confirm
+	except for the OPEN_PAREN case.
+
+	Fixes to not confirm declarations with an open paren where
+	an equal sign or other assignment-like token might be, so the
+	corresponding assignments to same-named CHAR*(*) arrays work:
+	(ffestb_decl_entsp_5_): Move assertion so we crash on that first,
+	if it turns out to be wrong, before the less-debuggable crash
+	on mistaken confirmation.
+	(ffestb_decl_entsp_6_, ffestb_decl_entsp_7_, ffestb_decl_entsp_8_):
+	Include OPEN_PAREN in list of assignment-only tokens.
+
+	Fix more diagnosed-crash bugs:
+	* stu.c (ffestu_sym_end_transition): ANY-ize an adjustable array
+	with bad dimension expressions even if still stateUNCERTAIN.
+	(ffestu_symter_end_transition_, ffestu_symter_exec_transition_):
+	Return TRUE for opANY as well.
+	For code elegance, move opSYMTER case into first switch.
+
+1996-11-17  Dave Love  <d.love@dl.ac.uk>
+
+	* lex.c: Fix last change.
+
+1996-11-14  Dave Love  <d.love@dl.ac.uk>
+
+	* Make-lang.in, config-lang.in: Remove the (broken) libU77 stuff,
+	pending 0.5.20.
+
+Thu Nov 14 15:40:59 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* bad.def (FFEBAD_UNIMPL_STMT): Explain that invalid

+
+1996-11-12  Dave Love  <d.love@dl.ac.uk>
+
+        * lex.c: Declare dwarfout routines.
+
+        * config-lang.in: Sink grep o/p.
+
+Mon Nov 11 14:21:13 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* g77.c (main): Might as well print version number
+	for --verbose as well.
+
+Thu Nov  7 18:41:41 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* expr.c, lang-options.h, target.h, top.c, top.h: Split out
+	remaining -fugly stuff into -fugly-logint and -fugly-comma,
+	leaving -fugly as simply a `macro' that expands into other
+	options, and eliminate defaults for some of the ugly stuff
+	in target.h.
+
+	* Make-lang.in (gcc-cross): Compile zzz.c, not version.o (!),
+	in to get version info for this target.
+
+	* config-lang.in: Test for GBE patch application based
+	on whether 2.6.x or 2.7.x GBE is detected.

+	* g77.c: Add support for --help and --version.
+
+	* g77.c (lookup_option): Short-circuit long-winded tests

+
+Sat Nov  2 13:50:31 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* intrin.def: Add FTELL and FSEEK intrinsics, plus new
+	`g' codes for alternate-return (GOTO) arguments.
+	* intrin.c (ffeintrin_check_): Support `g' codes.
+	* com-rt.def: Add ftell_() and fseek_() to database.
+	* com.c (ffecom_expr_intrinsic_): Ditto.  Also, let each
+	subroutine intrinsic decide for itself what to do with
+	tree_type, the default being NULL_TREE once again (so
+	ffecom_call_ doesn't think it's supposed to cast the
+	function call to the type in the fall-through case).
+
+	* ste.c (ffeste_R909_finish): Don't special-case list-directed
+	I/O, now that libf2c can return non-zero status codes.
+	(ffeste_R910_finish): Ditto.
+	(ffeste_io_call_): Simplify logic.
+	(ffeste_io_impdo_):
+	(ffeste_subr_beru_):
+	(ffeste_R904):
+	(ffeste_R907):
+	(ffeste_R909_start):

+
+Thu Oct 31 20:56:28 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* config-lang.in, Make-lang.in: Rename flag file
+	build-u77 to build-libu77, for consistency with
+	install-libf2c and such.
+
+	* config-lang.in: Don't complain about failure to patch
+	if pre-2.7.0 gcc is involved (since our patch for that
+	doesn't add support for tooning).
+
+Sat Oct 26 05:56:51 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* bad.def (FFEBAD_TYPELESS_TOO_LARGE): Remove this
+	unused and redundant diagnostic.
+
+Sat Oct 26 00:45:42 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* target.c (ffetarget_integerhex): Fix dumb bug.

+Sat Oct 19 03:11:14 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* bad.def, bld.c, bld.h, expr.c, lang-options.h, target.c,

+	ffebld_constant_new_integerhex, ffebld_constant_new_integeroctal,
+	ffeexpr_token_name_apos_name_, ffetarget_integerbinary,
+	ffetarget_integerhex, ffetarget_integeroctal): Support
+	new -fno-typeless-boz option with new functions, mods to
+	existing octal-handling functions, new macros, new error
+	messages, and so on.
+
+	* com.c, lang-options.h, top.c, top.h (ffecom_notify_primary_entry):
+	Print program unit name on stderr if -fno-silent (new option).
+
+	* lang-options.h, top.c, top.h, stt.c (ffestt_dimlist_as_expr):
+	Treat ([...,]1) in dimlist as ([...,]*) if -fugly-assumed
+	(new option).
+
+	* lang-options.h: Comment out options duplicated in gcc/toplev.c,
+	because, somehow, having them commented in and building on my
+	DEC Alpha results in a cc1 that always segfaults, and gdb that
+	also segfaults whenever it debugs it up to init_lex() calling
+	xmalloc() or so.
+
+Thu Oct 17 00:39:27 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* stb.c (ffestb_R10013_): Don't change meaning of .sign until
+	after previous meaning/value used to set sign of value
+	(960507-1.f).
+
+Sun Oct 13 22:15:23 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* top.c (ffe_decode_option): Don't set back-end flags
+	that are nonexistent prior to gcc 2.7.0.
+
+Sun Oct 13 12:48:45 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (convert): Don't convert emulated complex expr to
+	real (via REALPART_EXPR) if the target type is (emulated)
+	complex.
+
+Wed Oct  2 21:57:12 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_debug_kludge_): Set DECL_IN_SYSTEM_HEADER so
+	-Wunused doesn't complain about these manufactured decls.
+	(ffecom_expr_): Ditto, for original (non-ASSIGN'ed) variable.
+	(ffecom_transform_equiv_): Clear DECL_IGNORED_P for aggregate
+	area so it shows up as a debug-accessible symbol.
+	(pushdecl): Default for "invented" identifiers (a g77-specific
+	concept for now) is that they are artificial, in system header,
+	ignored for debugging purposes, used, and (for types) suppressed.
+	This ought to be overkill.
+
+Fri Sep 27 23:13:07 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* ste.c (ffeste_begin_iterdo_, ffeste_end_iterdo_): Support
+	one-trip DO loops (F66-style).
+	* lang-options.h, top.c, top.h (-fonetrip): New option.

+1996-09-24  Dave Love  <d.love@dl.ac.uk>
+
+	* Make-lang.in (include/f2c.h):
+	Remove dependencies on xmake_file and tmake_file.
+	They expand inconsistently in 2.8 c.f. 2.7; $(GCC_PARTS) depends on
+	them anyhow.
+
+1996-09-22  Dave Love  <d.love@dl.ac.uk>
+
+	* config-lang.in: Add --enable-libu77 option handling.
+
+	* Make-lang.in:
+	Conditionally add --enable-libu77 when running runtime configure.
+	Define LIBU77STAGESTUFF and use it in relevant rules.
+
+1996-08-21  Dave Love  <d.love@dl.ac.uk>
+
+	* Make-lang.in (f77-runtime):
+	`stmp-hdrs' should have been `stmp-headers'.
+
+1996-08-20  Dave Love  <d.love@dl.ac.uk>
+
+	* Make-lang.in (f77-runtime):
+	Depend on stmp-hdrs, not stmp-int-hdrs, since libF77
+	needs float.h.
+
+Sat Jun 22 18:17:11 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_tree_divide_): Fix RECORD_TYPE case to
+	look at type of first field, properly, to determine

+
+Mon May 27 16:23:43 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Changes to optionally avoid gcc's back-end complex support:
+	* com.c (ffecom_stabilize_aggregate_): New function.
+	(ffecom_convert_to_complex_): New function.
+	(ffecom_make_complex_type_): New function.
+	(ffecom_build_complex_constant_): New function.
+	(ffecom_expr_): For opCONVERT of non-COMPLEX to COMPLEX,
+	don't bother explicitly converting to the subtype first,
+	because gcc does that anyway, and more code would have
+	to be added to find the subtype for the emulated-complex
+	case.
+	(ffecom_f2c_make_type_): Use ffecom_make_complex_type_
+	instead of make_node etc. to make a complex type.
+	(ffecom_1, ffecom_2): Translate operations on COMPLEX operands
+	to appropriate operations when emulating complex.
+	(ffecom_constantunion): Use ffecom_build_complex_constant_
+	instead of build_complex to build a complex constant.
+	(ffecom_init_0): Change point at which types are laid out
+	for improved consistency.
+	Use ffecom_make_complex_type_ instead of make_node etc.
+	to make a complex type.
+	Always calculate storage sizes from TYPE_SIZE, never TYPE_PRECISION.
+	(convert): Use e, not expr, since we've copied into that anyway.
+	For RECORD_TYPE cases, do emulated-complex conversions.
+	(ffecom_f2c_set_lio_code_): Always calculate storage sizes
+	from TYPE_SIZE, never TYPE_PRECISION.
+	(ffecom_tree_divide_): Allow RECORD_TYPE to also be handled
+	by run-time library.

+	to AIMAG intrinsic.

+
+Mon May 20 02:06:27 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* target.h: Use new REAL_VALUE_UNTO_TARGET_* macros instead
+	of REAL_VALUE_FROM_TARGET_DOUBLE and _SINGLE.
+	Explicitly use long instead of HOST_WIDE_INT for emulation
+	of ffetargetReal1 and ffetargetReal2.
+
+1996-05-20  Dave Love  <d.love@dl.ac.uk>
+
+	* config-lang.in:
+	Test for patch being applied with flag_move_all_movables in toplev.c.
+
+	* install.texi (Patching GNU Fortran):
+	Mention overriding X_CFLAGS rather than
+	editing proj.h on SunOS4.
+
+	* Make-lang.in (F77_FLAGS_TO_PASS):
+	Add X_CFLAGS (convenient for SunOS4 kluge, in
+	particular).
+	(f77.{,mostly,dist}clean): Reorder things, in particular not to delete
+	Makefiles too early.
+
+	* g77.c (DEFAULT_SWITCH_TAKES_ARG): Define a la gcc.c in the
+	current GCC snapshot.
+
+Tue May 14 00:24:07 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	Changes for DEC Alpha AXP support:
+	* com.c (ffecom_init_0): REAL_ARITHMETIC means internal
+	REAL/DOUBLE PRECISION might well have a different size
+	than the compiled type, so don't crash if this is the
+	case.
+	* target.h: Use `int' for ffetargetInteger1,
+	ffetargetLogical1, and magical tests.  Set _f format
+	strings accordingly.
+
+Tue Apr 16 14:08:28 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* top.c (ffe_decode_option): -Wall no longer implies
+	-Wsurprising.
+
+Sat Apr 13 14:50:06 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_char_args_): If item is error_mark_node,
+	set *length that way, too.
+
+	* com.c (ffecom_expr_power_integer_): If either operand
+	is error_mark_node, return that.
+
+	* com.c (ffecom_intrinsic_len_): If item is error_mark_node,
+	return that for length.
+
+	* expr.c (ffeexpr_declare_unadorned_,
+	ffeexpr_declare_parenthesized_): Instead of crashing
+	on unexpected contexts, produce a diagnostic.
+
+	* intrin.c (ffeintrin_check_), intrin.def (impSIGNAL):
+	Allow procedure as second arg to SIGNAL intrinsic.
+
+	* stu.c (ffestu_symter_end_transition_): New function.
+	(ffestu_symter_exec_transition_): Return bool arg.
+	Always transition symbol (don't inhibit when !whereNONE).
+	(ffestu_sym_end_transition): If DUMMY/LOCAL arg has any
+	opANY exprs in its dimlist, diagnose it so it doesn't
+	make it through to later stages that try to deal with
+	dimlist stuff.
+	(ffestu_sym_exec_transition): If sym has any opANY exprs
+	in its dimlist, diagnose it so it becomes opANY itself.
+
+	* symbol.c (ffesymbol_error): If token arg is NULL,
+	just ANY-ize the symbol -- don't produce diagnostic.
+
+Mon Apr  1 10:14:02 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Version 0.5.18 released.
+
+Mon Mar 25 20:52:24 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_expr_power_integer_): Don't generate code
+	that compares COMPLEX (or, as it happens, REAL) via "LT_EXPR",
+	since the back end crashes on that.  (This code would never
+	be executed anyway, but the test that avoids it has now been
+	translated to control whether the code gets generated at all.)
+	Fixes 960323-3.f.
+
+	* com.c (ffecom_type_localvar_): Handle variable-sized
+	dimension bounds expressions here, so they get calculated
+	and saved on procedure entry.  Fixes 960323-4.f.
+
+	* com.c (ffecom_notify_init_symbol): Symbol has no init
+	info at all if only zeros have been used to initialize it.
+	Fixes 960324-0.f.
+
+	* expr.c, expr.h (ffeexpr_type_combine): Renamed from
+	ffeexpr_type_combine_ and now a public procedure; last arg now
+	a token, instead of an internal structure used to extract a token.
+	Now allows the outputs to be aliased with the inputs.
+	Now allows a NULL token to mean "don't report error".
+	(ffeexpr_reduced_bool2_, ffeexpr_reduced_eqop2_,
+	ffeexpr_reduced_math2_, ffeexpr_reduced_power_,
+	ffeexpr_reduced_relop2_): Handle new calling sequence for
+	ffeexpr_type_combine.
+	* (ffeexpr_convert): Don't put an opCONVERT node
+	in just because the size is unknown; all downstream code
+	should be able to deal without it being there anyway, and
+	getting rid of it allows new intrinsic code to more easily
+	combine types and such without generating bad code.
+	* info.c, info.h (ffeinfo_kindtype_max): Rewrite to do
+	proper comparison of size of types, not just comparison
+	of their internal kind numbers (so I2.eq.I1 doesn't promote
+	I1 to I2, rather the other way around).
+	* intrin.c (ffeintrin_check_): Combine types of arguments
+	in COL a la expression handling, for greater flexibility
+	and permissiveness (though, someday, -fpedantic should
+	report use of this kind of thing).
+	Make sure Hollerith/typeless where CHARACTER expected is
+	rejected.  This all fixes 960323-2.f.
+
+	* ste.c (ffeste_begin_iterdo_): Fix some more type conversions
+	so INTEGER*2-laden DO loops don't crash at compile time on
+	certain machines.  Believed to fix 960323-1.f.
+
+	* stu.c (ffestu_sym_end_transition): Certainly reject
+	whereDUMMY not in any dummy list, whether stateUNCERTAIN
+	or stateUNDERSTOOD.  Fixes 960323-0.f.
+
+Tue Mar 19 13:12:40 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* data.c (ffedata_value): Fix crash on opANY, and simplify
+	the code at the same time.
+
+	* Make-lang.in (f77-runtime): Also depends on lib[FI]77/Makefile...
+	(include/f2c.h...): ...which in turn depend on */Makefile.in.
+	(f77.rebuilt): Rebuild runtime stuff too.
+
+	* intrin.c (ffeintrin_check_): Accommodate TYPELESS/HOLLERITH
+	types, convert args as necessary, etc.
+
+	* expr.c (ffeexpr_convert): Fix test for TYPELESS/HOLLERITH
+	to obey the docs; crash if no source token when error.
+	(ffeexpr_collapse_convert): Crash if no token when error.
+
+Mon Mar 18 15:51:30 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_init_zero_): Renamed from
+	ffecom_init_local_zero_; now handles top-level
+	(COMMON) initializations too.
+
+	* bld.c (ffebld_constant_is_zero):
+	* com.c (ffecom_symbol_transform_, ffecom_sym_transform_assign_,
+	ffecom_transform_common_, ffecom_transform_equiv_):
+	* data.c:
+	* equiv.c:
+	* equiv.h:
+	* lang-options.h:
+	* stc.c:
+	* storag.c:
+	* storag.h:
+	* symbol.c:
+	* symbol.h:
+	* target.c:
+	* target.h:
+	* top.c:
+	* top.h: All of this is mostly housekeeping-type changes
+	to support -f(no-)zeros, i.e. not always stuff zero
+	values into the initializer fields of symbol/storage objects,
+	but still track that they have been given initial values.
+
+	* bad.def: Fix wording for DATA-related diagnostics.
+
+	* com.c (ffecom_sym_transform_assign_): Don't check
+	any EQUIVALENCE stuff for local ASSIGN, the check was
+	bad (crashing), and it's not necessary, anyway.
+
+	* com.c (ffecom_expr_intrinsic_): For MAX and MIN,
+	ignore null arguments as far arg[123], and fix handling
+	of ANY arguments.  (New intrinsic support now allows
+	spurious trailing null arguments.)
+
+	* com.c (ffecom_init_0): Add HOLLERITH (unsigned)
+	equivalents for INTEGER*2, *4, and *8, so shift intrinsics
+	and other things that need unsigned versions of signed
+	types work.
+
+Sat Mar 16 12:11:40 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* storag.c (ffestorag_exec_layout): Treat adjustable
+	local array like dummy -- don't create storage object.
+	* com.c (ffecom_sym_transform_): Allow for NULL storage
+	object in LOCAL case (adjustable array).
+
+Fri Mar 15 13:09:41 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_sym_transform_): Allow local symbols
+	with nonconstant sizes (adjustable local arrays).
+	(ffecom_type_localvar_): Allow dimensions with nonconstant
+	component (adjustable local arrays).
+	* expr.c: Various minor changes to handle adjustable
+	local arrays (a new case of stateUNCERTAIN).
+	* stu.c (ffestu_sym_end_transition,
+	ffestu_sym_exec_transition): Ditto.
+	* symbol.def: Update docs to reflect these changes.
+
+	* com.c (ffecom_expr_): Reduce space/time needed for
+	opACCTER case by handling it here instead of converting
+	it to opARRTER earlier on.
+	(ffecom_notify_init_storage): Don't convert ACCTER to ARRTER.
+	(ffecom_notify_init_symbol): Ditto.
+
+	* com.c (ffecom_init_0): Crash and burn if any of the types'
+	sizes, according to the GBE, disagrees with the sizes of
+	the FFE's internal implementation.  This might catch
+	Alpha/SGI bugs earlier.
+
+Fri Mar 15 01:09:41 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com-rt.def, com.c, com.h: Changes for rewrite of intrinsic

+
+	* expr.c (ffeexpr_token_name_rhs_): Go back to getting
+	type from specific, not implementation, info.
+	(ffeexpr_token_funsubstr_): Set intrinsic implementation too!
+	* intrin.c: Major rewrite of most portions.
+	* intrin.def: Major rearchitecting of tables.
+	* intrin.h (ffeintrin_basictype, ffeintrin_kindtype):
+	Now (once again) take ffeintrinSpec as arg, not ffeintrinImp;
+	for now, these return NONE, since they're not really needed
+	and adding the necessary info to the tables is not trivial.
+	(ffeintrin_codegen_imp): New function.
+	* stc.c (ffestc_R1208_item): Change way ffeintrin funcs called,
+	back to original per above; but comment out the code anyway.
+
+	* intrin.c (ffe_init_0): Do internal checks only if
+	-fset-g77-defaults not specified.
+
+	* lang-options.h: Add -fset-g77-defaults option.

+
+Sat Mar  9 17:49:50 1996  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* Make-lang.in (stmp-int-hdrs): Use --no-validate when
+	generating the f77.rebuilt files (BUGS, INSTALL, NEWS)
+	so cross-references can work properly in g77.info
+	without a lot of hassle.  Users can probably deal with
+	the way they end up looking in the f77.rebuilt files.
+
+	* bld.c (ffebld_constant_new_integer4_val): INTEGER*8
+	support -- new function.
+	(ffebld_constant_new_logical4_val): New function.
+	* com.c (ffecom_f2c_longint_type_node): New type.
+	(FFECOM_rttypeLONGINT_): New return type code.
+	(ffecom_expr_): Add code to invoke pow_qq instead
+	of pow_ii for INTEGER4 (INTEGER*8) case.
+	If ffecom_expr_power_integer_ returns NULL_TREE, just do
+	the usual work.
+	(ffecom_make_gfrt_): Handle new type.
+	(ffecom_expr_power_integer_): Let caller do the work if in
+	dummy-transforming case, since
+	caller now knows about INTEGER*8 and such, by returning
+	NULL_TREE.
+	* expr.c (ffeexpr_reduced_power_): Complain about non-INTEGER
+	raised to INTEGER4 (INTEGER*8) power.
+
+	* target.c (ffetarget_power_integerdefault_integerdefault):
+	Fix any**negative.
+	* com.c (ffecom_expr_power_integer_): Fix (-1)**(-8) and similar
+	to ABS() the integral result if the exponent is negative
+	and even.

+	(ffestb_decl_R5395_): Ditto.
+	* stc.c (ffestc_establish_declstmt_): Ditto.
+	* std.c (ffestd_R539item): Ditto.
+	(ffestd_R1219): Ditto.
+	* stp.h: Ditto.
+	* str-1t.fin: Ditto.
+	* str-2t.fin: Ditto.
+
+	* expr.c (ffeexpr_finished_): For DO loops, allow
+	any INTEGER type; convert LOGICAL (assuming -fugly)
+	to corresponding INTEGER type instead of always default
+	INTEGER; let later phases do conversion of DO start,
+	end, incr vars for implied-DO; change checks for non-integral
+	DO vars to be -Wsurprising warnings.
+	* ste.c (ffeste_io_impdo_): Convert start, end, and incr
+	to type of DO variable.
+
+	* com.c (ffecom_init_0): Add new types for [IL][234],
+	much of which was done by Scott Snyder <snyder@d0sgif.fnal.gov>.
+	* target.c: Ditto.
+	* target.h: Ditto.

+Wed Mar  6 14:08:45 1996  Craig Burley  <burley@gnu.ai.mit.edu>

+	Reorganize the *clean rules to more closely parallel gcc's.
+
+	* config-lang.in: Exclude g77.info from diffs.
+
+Sun Dec 10 02:29:13 1995  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* expr.c (ffeexpr_declare_unadorned_,
+	ffeexpr_declare_parenthesized_): Break out handling of
+	contextDATAIMPDO[INDEX,CTRL] so it's independent of symbol state.
+	Don't exec-transition these here (let ffeexpr_sym_impdoitem_
+	handle that when appropriate).  Don't "declare" them twice.
+
+Tue Dec  5 06:48:26 1995  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* stc.c (ffestc_promote_sfdummy_): Allow whereNONE parent
+	symbol, since it is not necessarily known whether it will
+	become LOCAL or DUMMY.
+
+Mon Dec  4 03:46:55 1995  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* lex.c (ffelex_display_token, ffelex_type_string_): Resurrect

+	from debugger.
+	* lex.h (ffelex_display_token): Declare this in case anyone
+	else wants to call it.
+
+	* lex.c (ffelex_total_tokens_): Have this reflect actual allocated
+	tokens, no longer include outstanding "uses" of tokens.
+
+	* malloc.c, malloc.h (MALLOC_DEBUG): New macro to control
+	checking of whether callers follow rules, now defaults to 0
+	for "no checking" to improve compile times.
+
+	* malloc.c (malloc_pool_kill): Fix bug that could prevent
+	subpool from actually being killed (wasn't setting its use
+	count to 1).
+
+	* proj.h, *.c (dmpout): Replace all occurrences of `stdout'
+	and some of `stderr' with `dmpout', so where to dump debugging
+	output can be easily controlled during build; add default
+	for `dmpout' of `stderr' to proj.h.
+
+Sun Dec  3 00:56:29 1995  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* com.c (ffecom_return_expr): Eliminate attempt at warning
+	about unset return values, since the back end does this better,
+	with better wording, and is not triggered by clearly working
+	(but spaghetti) code as easily as this test.
+
+Sat Dec  2 08:28:56 1995  Craig Burley  <burley@gnu.ai.mit.edu>
+
+	* target.c (ffetarget_power_*_integerdefault): Raising 0 to
+	integer constant power should not be an error condition;

+
+	* bad.def (FFEBAD_BAD_POWER): 0**integer now a warning instead
+	of an error.
+
+Fri Dec  1 00:12:03 1995  Craig Burley  (burley@gnu.ai.mit.edu)

+	has any content, not just if it finishes a previous line
+	or has a label.
+	(ffelex_file_free): Clarify switch statement code.
+
+Sat Nov 18 19:37:22 1995  Craig Burley  (burley@gnu.ai.mit.edu)

+
+	* Make-lang.in: Fix typo in comment.
+
+	* Makefile.in (f/fini.o, f/proj-h.o): Don't use `$<' since
+	not all makes support it (e.g. NeXT make), use explicit
+	source name instead (with $(srcdir) and munging).
+	(ASSERT_H): assert.h lives in source dir, not build dir.
+
+Thu Nov 16 12:47:50 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_init_0): Fix dumb bug in code to produce
+	warning message about non-32-bit-systems.
+
+	* stc.c (ffestc_R501_item): Parenthesize test to make
+	warning go away (and perhaps fix bug).
+
+Thu Nov 16 03:43:33 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* g77.c: Upgrade to 2.7.0's gcc.c.
+	Fix -v to pass a temp name instead of "/dev/null" for "-o".
+
+Fri Nov 10 19:16:05 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* ste.c (ffeste_begin_iterdo_): Add Toon's change to
+	make loops faster on some machines (implement termination
+	condition as "--i >= 0" instead of "i-- > 0").
+
+Thu Nov  2 03:58:17 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Make-lang.in: Remove unnecessary $(exeext) a la cp/Make-lang.in.
+
+	* com.c (ffecom_expr_): Restore old strategy for assignp variant
+	of opSYMTER case...always return the ASSIGN version of var.
+	That way, `-O -Wuninitialized' will catch "I=3;GOTO I;END"
+	(though the diagnostic will refer to `__g77_ASSIGN_i').
+
+	* com.c (ffecom_expr_power_integer_): For constant rhs case,
+	wrap every new eval of lhs in save_expr() so it is clear to
+	back end that MULT_EXPR(lhs,lhs) has identical operands,
+	otherwise for an rhs like 32767 it generates around 65K pseudo
+	registers, with which stupid_life_analysis cannot cope
+	(due to reg_renumber in regs.h being `short *' instead of
+	`int *').
+
+	* com.c (ffecom_expr_): Speed up implementation of LOGICAL
+	versions of opNOT, opAND, opOR, opXOR/opNEQV, and opEQV by
+	assuming the values actually are kosher LOGICAL bit patterns.
+	Also simplify code that implements some of the INTEGER versions
+	of these.
+
+	* com.c (skip_redundant_dir_prefix, read_name_map,
+	ffecom_open_include_, signed_type, unsigned_type): Fold in
+	changes to cccp.c made from 2.7.0 through ss-950826.
+
+	* equiv.c (ffeequiv_layout_local_): Kill the equiv list
+	if no syms in list.
+
+	* expr.c (ffeexpr_reduced_eqop2_): Issue specific diagnostic
+	regarding usage of .EQV./.NEQV. in preference to .EQ./.NE..
+
+	* intrin.c: Add ERF and ERFC as generic intrinsics.
+	intrin.def: Same.
+
+	* sta.c (ffesta_save_, ffesta_second_): Whoever calls
+	ffestd_exec_begin must also set ffesta_seen_first_exec = TRUE,
+	and anytime stc sees an exec transition, it must do both.
+	stc.c (ffestc_eof): Same.
+
+	* stc.c (ffestc_promote_sfdummy_): If failed implicit typing
+	or CHARACTER*(*) arg, after calling ffesymbol_error, don't
+	reset info to ENTITY/DUMMY, because ffecom_sym_transform_
+	doesn't expect such a thing with ANY/ANY type.
+
+	* target.h (*logical*): Change some of these so they parallel
+	changes in com.c, e.g. for _eqv_, use (l)==(r) instead of
+	!!(l)==!!(r), to get a more faithful result.
+
+Fri Oct 27 07:06:59 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_sym_transform_): Simplify code for local
+	EQUIVALENCE case.
+
+	* expr.c (ffeexpr_exprstack_push_unary_): Warn about two
+	successive operators.
+	(ffeexpr_exprstack_push_binary_): Warn about "surprising"
+	operator precedence, as in "-2**2".
+
+	* lang-options.h: Add -W(no-)surprising options.
+
+	* parse.c (yyparse): Don't reset -fpedantic if not -pedantic.
+
+	* top.c (ffe_decode_option): Support new -Wsurprising option.
+	* top.h: Ditto.
+
+Mon Oct 23 09:14:15 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_finish_symbol_transform_): Don't transform
+	NONE/NONE (CHARACTER*(*)) vars, as these don't mean anything
+	in debugging terms, and can't be turned into anything
+	in the back end (so ffecom_sym_transform_ crashes on them).
+
+	* com.c (ffecom_expr_): Change strategy for assignp variant
+	of opSYMTER case...always return the original var unless
+	it is not wide enough.
+
+	* ste.c (ffeste_io_cilist_): Clarify diagnostic for ASSIGN
+	involving too-narrow variable.  This shouldn't happen, though.
+	(ffeste_io_icilist_): Ditto.
+	(ffeste_R838): Ditto.
+	(ffeste_R839): Ditto.
+
+Thu Oct 19 03:21:20 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_sym_transform_assign_): Set TREE_STATIC
+	using the same decision-making process as used for their twin
+	variables, so ASSIGN can last across RETURN/CALL as appropriate.
+
+Fri Sep 22 20:21:18 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Makefile.in: fini is a host program, so it needs a host-compiled
+	version of proj.o, named proj-h.o.  f/fini, f/fini.o, and
+	f/proj-h.o targets updated accordingly.
+
+	* com.c (__eprintf): New function.
+
+Wed Sep 20 02:26:36 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* lang-options.h: Add omitted -funix-intrinsics-* options.
+
+	* malloc.c (malloc_find_inpool_): Check for infinite
+	loop, crash if detected (user reports encountering
+	them in some large programs, this might help track
+	down the bugs).
+
+Thu Sep  7 13:00:32 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (lang_print_error_function): Don't dereference null
+	pointer when outside any program unit.
+	(ffecom_let_char_, ffecom_arg_ptr_to_expr): If catlist
+	item or length ever error_mark_node, don't continue processing,
+	since back-end functions like build_pointer_type crash on
+	error_mark_node's (due to pushing bad obstacks, etc.).
+
+Wed Aug 30 15:58:35 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.16 released.
+
+Mon Aug 28 12:24:20 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* bad.c (ffebad_finish): Fix botched message when no places
+	are printed (due to unknown line info, etc.).
+
+	* std.c (ffestd_subr_labels_): Do a better job finding
+	line info in the case of typeANY and diagnostics.
+
+Fri Aug 25 15:19:29 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (DECL_ARTIFICIAL): Surround all references to this
+	macro with #if !BUILT_FOR_270 and #endif.
+	(init_lex): Surround print_error_function decl with
+	#if !BUILT_FOR_270 and #endif.
+	(lang_init): Call new ffelex_hash_kludge function to solve
+	problem with preprocessed files that have INCLUDE statements.
+
+	* lex.c (ffelex_getc_): New function.
+	(ffelex_cfelex_): Use ffelex_getc_ instead of getc in any
+	paths of code that can be affected by ffelex_hash_kludge.
+	Don't make an EOF token for unrecognized token; set token
+	to NULL instead, to avoid problems when not initialized.
+	(ffelex_hash_): Use ffelex_getc_ instead of getc in any
+	paths of code that can be affected by ffelex_hash_kludge.
+	Test token returned by ffelex_cfelex_ for NULL, meaning
+	unrecognized token.
+	Get rid of useless used_up variable.
+	Don't do ffewhere stuff or kill any tokens if in
+	ffelex_hash_kludge.
+	(ffelex_file_fixed, ffelex_file_free): Use ffelex_getc_
+	instead of getc in any paths of code that can be affected
+	by ffelex_hash_kludge.
+	(ffelex_hash_kludge): New function.
+
+	* lex.h (ffelex_hash_kludge): New function.
+
+Wed Aug 23 15:17:40 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c: Implement -f(no-)underscoring options by always
+	compiling in code to do it, and having that code inhibit
+	itself when -fno-underscoring is in effect.  This option
+	overrides -f(no-)f2c for this purpose; -f(no-)f2c returns
+	to it's <=0.5.15 behavior of affecting only how code
+	is generated, not how/whether names are mangled.
+
+	* target.h: Redo specification of appending underscores so
+	the macros are named "_default" instead of "_is" and the
+	two-underscore macro defaults to 1.
+
+	* top.c, top.h (underscoring): Add appropriate stuff
+	for the -f(no-)underscoring options.
+
+Tue Aug 22 10:25:01 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* bad.c (ffebad_finish): Call report_error_function (in toplev.c)
+	to better identify location of problem.
+	Say "(continued):" instead of "(continued:)" for consistency.
+
+	* com.c (ffecom_gen_sfuncdef_): Set and reset new
+	ffecom_nested_entry_ variable to hold ffesymbol being compiled.
+	(lang_print_error_function): New function from toplev.c.
+	Use ffecom_nested_entry_ to help determine which name
+	and kind-string to print.
+	(ffecom_expr_intrinsic_): Handle EXIT and FLUSH invocations
+	with different calling sequences than library functions.
+	Have SIGNAL and SYSTEM push and pop calltemps, and convert
+	their return values to the destination type (just in case).
+	(FFECOM_rttypeINT_): New return type for `int', in case
+	gcc/f/runtime/libF77/system_.c(system_) is really supposed
+	to return `int' instead of `ftnint'.
+
+	* com.h (report_error_function): Declare this.
+
+	* equiv.c (ffeequiv_layout_local_): Don't forget to consider
+	root variable itself as possible "first rooted variable",
+	else might never set symbol and then crash later.
+
+	* intrin.c (ffeintrin_check_exit_): Change to allow no args
+	and rename to ffeintrin_check_int_1_o_ for `optional'.
+	#define ffeintrin_check_exit_ and _flush_ to this new
+	function, so intrin.def can refer to the appropriate names.
+
+	* intrin.def (FFEINTRIN_impFLUSH): Validate using
+	ffeintrin_check_flush_ so passing an INTEGER arg is allowed.
+
+	* lex.c (ffelex_file_push_, ffelex_file_pop_): New functions
+	to manage input_file_stack in gbe.
+	(ffelex_hash_): Call new functions (instead of doing code).
+	(ffelex_include_): Call new functions to update stack for
+	INCLUDE (_hash_ handles cpp output of #include).
+
+Mon Aug 21 08:09:04 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Makefile.in: Put `-W' in front of every `-Wall', since
+	2.7.0 requires that to engage `-Wunused' for parameters.
+
+	* com.c: Mark all parameters as artificial, so
+	`-W -Wunused' doesn't complain about unused ones (since
+	there's no way right not to individually specify attributes
+	like `unused').
+
+	* proj.h: Don't #define UNUSED if already defined, regardless
+	of host compiler.
+
+Sun Aug 20 16:03:56 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* gbe/2.7.0.diff: Regenerate.
+
+	* lang-options.h, lang-specs.h: If not __STDC__ (ANSI C),
+	avoid doing anything, especially the stringizing in -specs.h.
+
+Thu Aug 17 03:36:12 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* lang-specs.h: Remove useless optional settings of -traditional,
+	since -traditional is always set anyway.
+
+Wed Aug 16 16:56:46 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Make-lang.in (F2C_INSTALL_FLAG, F2CLIBOK): More
+	control over whether to install f2c-related stuff.
+	(install-f2c-*): New targets to install f2c-related
+	stuff in system, not just gcc, directories.
+
+	* com.c: Change calls to ffecom_get_invented_identifier
+	to use generally more predictable names.
+	Change calls to build_range_type to ensure consistency
+	of types of operands.
+	(ffecom_get_external_identifier_): Change to accept
+	symbol info, not just text, so it can use f2c flag for
+	symbol to decide whether to append underscore(s).
+	(ffecom_get_identifier_): Don't change names if f2c flag
+	off for compilation.
+	(ffecom_type_permanent_copy_): Use same type for new max as
+	used for min.
+	(ffecom_notify_init_storage): Offline fixups for stand-alone.
+
+	* data.c (ffedata_gather): Explicitly test for common block,
+	since it's no longer always the case that a local EQUIVALENCE
+	group has no symbol ptr (it now can, if a user-predictable
+	"rooted" symbol has been identified).
+
+	* equiv.c: Add some debugging stuff.
+	(ffeequiv_layout_local_): Set symbol ptr with user-predictable
+	"rooted" symbol, for giving the invented aggregate a
+	predictable name.
+
+	* g77.c (append_arg): Allow for 20 extra args instead of 10.
+	(main): For version-only case, add `-fnull-version' and, unless
+	explicitly omitted, `-lf2c -lm'.
+
+	* lang-options.h: New "-fnull-version" option.
+
+	* lang-specs.h: Support ".fpp" suffix for preprocessed source
+	(useful for OS/2, MS-DOS, other case-insensitive systems).
+
+	* stc.c (ffestc_R544_equiv_): Swap way lists are merged so this
+	is consistent with the order in which lists are built, making
+	user predictability of invented aggregate name much higher.
+
+	* storag.c, storag.h (FFESTORAG_typeDUMMY): Delete this enum.
+
+	* top.c: Accept, but otherwise ignore, `-fnull-version'.
+
+Tue Aug 15 07:01:07 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* DOC, INSTALL, PROJECTS: Extensive improvements to documentation.
+
+Sun Aug 13 01:55:18 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* INSTALL (f77-install-ok): Document the use of this file.
+
+	* Make-lang.in (F77_INSTALL_FLAG): New flag to control
+	whether to install an `f77' command (based on whether
+	a file named `f77-install-ok' exists in the source or
+	build directory) to replace the broken attempt to use
+	comment lines to avoid installing `f77' (broken in the
+	sense that it prevented installation of `g77').
+
+Mon Aug  7 06:14:26 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* DOC: Add new sections for g77 & gcc compiler options,
+	source code form, and types, sizes and precisions.
+	Remove lots of old "delta-version" info, or at least
+	summarize it.
+
+	* INSTALL: Add info here that used to be in DOC.
+	Other changes.
+
+	* g77.c (lookup_option, main): Check for --print-* options,
+	so we avoid adding version-determining stuff.
+
+Wed Jul 26 15:51:03 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Make-lang.in, Makefile.in (input.j, INPUT_H): New file.

+
+	* bad.c (ffebad_here): Okay to use unknown line/col.
+
+	* compilers.h (@f77-cpp-input): Remove -P option now that
+	# directives are handled by f771.  Update other options
+	to be more consistent with @c in gcc/gcc.c.  Don't run f771
+	if -E specified, etc., a la @c.
+	(@f77): Don't run f771 if -E specified, etc., a la @c.
+
+	* config-lang.in: Avoid use of word "guaranteed".

+	(ffelex_get_directive_line_): New function.
+	(ffelex_hash_): New function.

+	Also fix bug in pointing to next line (for diagnostics, &c)
+	following successful INCLUDE.
+	(ffelex_next_line_): New function that does chunk of code
+	seen in several places elsewhere in the lexers.
+	(ffelex_file_fixed): Delay finishing statement until source
+	line is registered with ffewhere, so INCLUDE processing
+	picks up the info correctly.
+	Okay to kill or use unknown line/col objects now.
+	Handle HASH (#) lines.
+	Reorder tests for insubstantial lines to put most frequent
+	occurrences at top, for possible minor speedup.
+	Some general consolidation of code.
+	(ffelex_file_free): Handle HASH (#) lines.
+	Okay to kill or use unknown line/col objects now.
+	Some general consolidation of code.
+	(ffelex_init_1): Detect HASH (#) lines.
+	(ffelex_set_expecting_hollerith): Okay to kill or use unknown
+	line/col objects now.
+
+	* lex.h (FFELEX_typeHASH): New enum.
+
+	* options-lang.h (-fident, -fno-ident): New options.
+
+	* stw.c (ffestw_update): Okay to kill unknown line/col objects
+	now.
+
+	* target.h (FFETARGET_okREALQUAD, FFETARGET_okCOMPLEXDOUBLE,
+	FFETARGET_okCOMPLEXQUAD): #define these appropriately.
+
+	* top.c: Include flag.j wrapper, not flags.h directly.
+	(ffe_is_ident_): New flag.
+	(ffe_decode_option): Handle -fident and -fno-ident.
+	(ffe_file): Replace obsolete ffewhere_file_(begin|end) with

+
+Mon Jul 17 03:04:09 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_sym_transform_): Set DECL_IN_SYSTEM_HEADER
+	flag for any local vars used as stmtfunc dummies or DATA
+	implied-DO iter vars, so no -Wunused warnings are produced
+	for them (a la f2c).
+	(ffecom_init_0): Do "extern int xargc;" for IARGC() intrinsic.
+	Warn if target machine not 32 bits, since g77 isn't yet
+	working on them at all well.
+
+	* expr.c (ffeexpr_sym_lhs_call_, ffeexpr_sym_lhs_data_,
+	ffeexpr_sym_lhs_extfunc_, ffeexpr_sym_rhs_actualarg_,
+	ffeexpr_sym_rhs_let_, ffeexpr_paren_rhs_let_): Don't
+	gratuitously set attr bits that don't apply just
+	to avoid null set meaning error; instead, use explicit
+	error flag, and allow null attr set, to
+	fix certain bugs discovered by looking at this code.
+
+	* g77.c: Major changes to improve support for gcc long options,
+	to make `g77 -v' report more useful info, and so on.
+
+Mon Jul  3 14:49:16 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* DOC, com.c, intrin.h, intrin.c, intrin.def, target.h, top.c,
+	top.h: Add new `unix' group of intrinsics, which includes the
+	newly added ERF, ERFC, EXIT, plus even newer ABORT, DERF, DERFC,
+	FLUSH, GETARG, GETENV, SIGNAL, and SYSTEM.
+
+Tue Jun 27 23:01:05 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* bld.c, bld.h (ffebld_constant_pool,
+	ffebld_constant_character_pool): Use a single macro (the
+	former) to access the pool for allocating constants, instead
+	of latter in public and FFEBLD_CONSTANT_POOL_ internally
+	in bld.c (which was the only one that was correct before
+	these changes).  Add verification of integrity of certain
+	heap-allocated areas.
+
+	* com.c (ffecom_overlap_, ffecom_args_overlap_,
+	ffecom_tree_canonize_ptr_, ffecom_tree_canonize_ref_): New
+	functions to optimize calling COMPLEX and, someday, CHARACTER
+	functions requiring additional argument to be passed.
+	(ffecom_call_, ffecom_call_binop_, ffecom_expr_,
+	ffecom_expr_intrinsic_): Change calling
+	sequences to include more info on possible destination.
+	(ffecom_expr_intrinsic_): Add ERF(), ERFC(), and EXIT()
+	intrinsic code.
+	(ffecom_sym_transform_): For assumed-size arrays, set high
+	bound to highest possible value instead of low bound, to
+	improve validity of overlap checking.
+	(duplicate_decls): If olddecl and newdecl are the same,
+	don't do any munging, just return affirmative.
+
+	* expr.c: Change ffecom_constant_character_pool() to
+	ffecom_constant_pool().
+
+	* info.c (ffeinfo_new): Compile this version if not being
+	compiled by GNU C.
+
+	* info.h (ffeinfo_new): Don't define macro if not being
+	compiled by GNU C.
+
+	* intrin.c, intrin.def: Add ERF(), ERFC(), and EXIT() intrinsics.
+	(ffeintrin_check_exit_): New for EXIT() subroutine intrinsic.
+
+	* malloc.c, malloc.h (malloc_verify_*): New functions to verify
+	integrity of heap-storage areas.
+
+	* stc.c (ffestc_R834, ffestc_R835): Handle possibility that
+	an enclosing DO won't have a construct name even when the
+	CYCLE/EXIT does (i.e. without dereferencing NULL).
+
+	* target.c, target.h (ffetarget_verify_character1): New function
+	to verify integrity of heap storage used to hold character constant.
+
+Thu Jun 22 15:36:39 1995  Howard Gordon  (flash@super.org)
+
+	* stp.h (ffestpVxtcodeIx): Fix typo in typedef for this.
+
+Mon May 29 15:22:31 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* *: Make all sorts of changes to accommodate upcoming gcc-2.7.0.
+	I didn't keep track of them, nor just when I made them, nor
+	when I (much later, probably in early August 1995) modified
+	them so they could properly handle both 2.7.0 and 2.6.x.
+
+	* com.c (ffecom_expr_power_integer_): Don't expand_start_stmt_expr
+	if transforming dummy args, because the back end cannot handle
+	that (it's rejected by the gcc front end), just generate
+	call to run-time library.
+	Back out changes in 0.5.15 because more temporaries might be
+	needed anyway (for COMPLEX**INTEGER).
+	(ffecom_push_tempvar): Remove inhibitor.
+	Around start_decl and finish_decl (in particular, arround
+	expand_decl, which is called by them), push NULL_TREE into
+	sequence_rtl_expr, an external published by gcc/function.c.
+	This makes sure the temporary is truly in the function's
+	context, not the inner context of a statement-valued expression.
+	(I think the back end is inconsistent here, but am not
+	interested in convincing the gbe maintainers about this now.)
+	(pushdecl): Make sure that when pushing PARM_DECLs, nothing
+	other than them are pushed, as happened for 0.5.15 and which,
+	if done for other reasons not fixed here, might well indicate
+	some other problem -- so crash if it happens.
+
+	* equiv.c (ffeequiv_layout_local_): If the local equiv group
+	has a non-nil COMMON field, it should mean that an error has
+	occurred and been reported, so just trash the local equiv
+	group and do nothing.
+
+	* stc.c (ffestc_promote_sfdummy_): Set sfdummy arg state to
+	UNDERSTOOD so above checking for duplicate args actually
+	works, and so we don't crash later in pushdecl.
+
+	* ste.c (ffeste_R1001): Set initial value only for VAR_DECLs,
+	not for, e.g., LABEL_DECLs, which the FORMAT label can be
+	if it was previously treated as an executable label.
+
+Sat May 20 01:53:53 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_sym_transform_): For adjustable arrays,
+	pass high bound through variable_size in case its primaries
+	are changed (dumb0.f, and this might also improve
+	performance so it approaches f2c|gcc).
+
+Fri May 19 11:00:36 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.15 released.
+
+	* com.c (ffecom_expr_power_integer_): Push temp vars
+	before expanding a statement expression, since that seems
+	to cause temp vars to be "forgotten" after the end of the
+	expansion in the back end.  Disallow more temp-var
+	pushing during such an expansion, just in case.
+	(ffecom_push_tempvar): Crash if a new variable needs to be
+	pushed but cannot be at this point (should never happen).

+
+	* expr.c (ffeexpr_collapse_convert): Add code to convert

+	* target.h, target.c (ffetarget_convert_character1_logical1):
+	New function.

+	* lex.c (ffelex_send_token_): If sending CHARACTER token with

+	(ffelex_image_char_): When setting ffelex_bad_line_ to TRUE,
+	always "close" card image by appending a null char and setting

+	to identify the two kinds of problems that involve this.
+	(ffelex_file_fixed): Reset ffelex_bad_line_ to FALSE after
+	seeing a line with invalid first character (fixes 950508-1.f).
+	If final nontab column is zero, assume tab seen in line.

+	opening and diagnosing errors with INCLUDE files.
+
+	* ste.c (ffeste_begin_iterdo_): Use correct algorithm for
+	calculating # of iterations -- mathematically similar but
+	computationally different algorithm was not handling cases
+	like "DO I=6,5,2" correctly, because (5-6)/2+1 => 1, not 0.
+
+	* top.c (ffe_decode_option): Allow -I, restructure a bit

+	* Make-lang.in (F77_SRCS): Remove g77.c, since it doesn't
+	contribute to building f771.
+
+	* Makefile.in (dircheck): Remove/replace with f/Makefile, because
+	phony targets that are referenced in other real targets get run
+	when those targets are specified, which is a waste of time (e.g.
+	when rebuilding and only g77.c has changed, f771 was being linked
+	anyway).
+
+	* g77.c: Include -lc between -lf2c and -lm throughout.

+	type to keep DCMPLX(I) from crashing the compiler.
+	(ffecom_expr_): Don't convert result from ffecom_tree_divide_.
+	(ffecom_tree_divide_): Add tree_type argument, have all callers
+	pass one, and don't convert right-hand operand to it (this is

+	code used in ffecom_expr_ as possible).
+
+	* lex.c: Maintain lineno and input_filename the way the gcc
+	lexer does.
+
+	* std.c (ffestd_exec_end): Save and restore lineno and

+
+	* com.c (ffecom_expr_power_integer_): New function.

+	(ffecom_tree_divide_): New function.
+
+Wed Apr  5 14:15:44 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* lex.c: Change to allocate text for tokens only when actually
+	needed, which should speed compilation up somewhat.
+	Change to allow INCLUDE at any point where a statement
+	can end, i.e. in ffelex_finish_statement_ or when a SEMICOLON
+	token is sent.
+	Remove some old, obsolete code.
+	Clean up layout of entire file to improve formatting,
+	readability, etc.
+	(ffelex_set_expecting_hollerith): Remove include argument.

+	* Version 0.5.9 released.
+
+	* Make-lang.in (f/proj.h): touch file to register update,
+	because the previous commands won't necessarily modify it.
+
+	* Makefile.in (f/proj.h): touch file to register update,
+	because the previous commands won't necessarily modify it.
+
+	* Makefile.in (f/str-*.h, f/str-*.j): Explicitly specify
+	output file names, so these targets go in build, not source,
+	directory.
+
+	* bits.c, bits.h: Switch to valid ANSI C replacement for
+	ARRAY_ZERO.
+
+	* com.c (ffecom_expr_): Add assignp arg to support ASSIGN better.
+	If assignp is TRUE, use different tree for FFEBLD_opSYMTER case.
+	(ffecom_sym_transform_assign_): New function.
+	(ffecom_expr_assign): New function.
+	(ffecom_expr_assign_w): New function.
+
+	* com.c (ffecom_f2c_make_type_): Do make_signed_type instead
+	of make_unsigned_type throughout.
+
+	* com.c (ffecom_finish_symbol_transform_): Expand scope of
+	commented-out code to probably produce faster compiler code.
+
+	* com.c (ffecom_gen_sfuncdef_): Push/pop calltemps so
+	COMPLEX works right.
+	Remove obsolete comment.
+
+	* com.c (ffecom_start_progunit_): If non-multi alt-entry
+	COMPLEX function, primary (static) entry point returns result
+	directory, not via extra arg -- to agree with ffecom_return_expr
+	and others.
+	Pretransform all symbols so statement functions are defined
+	before any code emitted.
+
+	* com.c (ffecom_finish_progunit): Don't posttransform all
+	symbols here -- pretransform them instead.
+
+	* com.c (ffecom_init_0): Don't warn about possible ASSIGN
+	crash, as this shouldn't happen now.

+	pushed while context is a statement (nested) function, and
+	add appropriate commentary.
+
+	* com.c (ffecom_return_expr): Check TREE_USED to determine
+	where return value is unset.
+
+	* com.h (struct _ffecom_symbol_): Add note about length_tree
+	now being used to keep tree for ASSIGN version of symbol.
+
+	* com.h (ffecom_expr_assign, ffecom_expr_assign_rw): New decls.
+	(error): Add this prototype for back-end function.
+
+	* fini.c (main): Grab input, output, and include names
+	directly off the command line instead of making the latter
+	two out of the first.
+
+	* lex.c: Improve tab handling for both fixed and free source
+	forms, and ignore carriage-returns on input, while generally
+	improving the code.  ffelex_handle_tab_ has been renamed and
+	reinvented as ffelex_image_char_, among other things.
+
+	* malloc.c, malloc.h: Switch to valid ANSI C replacement for
+	ARRAY_ZERO, and kill the full number of bytes in pools and
+	areas.
+
+	* proj.h.in (ARRAY_ZERO, ARRAY_ZERO_SIZE): Remove.
+
+	* ste.c (ffeste_io_cilist_, ffeste_io_icilist_, ffeste_R838,

+	ASSIGN context despite changes to this code and code in com.c.
+
+	* where.c, where.h: Switch to valid ANSI C replacement for
+	ARRAY_ZERO.
+
+Fri Feb 17 03:35:19 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.8 released.
+
+	* INSTALL: In quick-build case, list g77 target first so g77
+	gets installed.  Also, explain that gcc gets built and installed
+	as well, even though this isn't really what we want (and maybe
+	we'll find a way around this someday).
+
+Fri Feb 17 02:35:41 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.7 released.
+
+	* Makefile.in (CONFIG_H, HCONFIG_H, TCONFIG_H, TM_H): Remove
+	../ prefix in front of .h files, since they're in the cd.
+
+Fri Feb 17 01:50:48 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.6 released.
+
+Thu Feb 16 20:26:54 1995  Craig Burley  (burley@gnu.ai.mit.edu)

+
+	* CREDITS: More changes.
+
+	* Make-lang.in (G77STAGESTUFF): Remove cktyps stuff.
+
+	* Makefile.in (CONFIG_H, HCONFIG_H, TCONFIG_H, TM_H): Don't
+	prefix gcc dir with $(srcdir) since these don't live there,
+	they are created in the build dir by gcc's configure.  Add
+	a note explaining what these macros are about.
+	Update dependencies via deps-kinda.
+
+	* README.NEXTSTEP: Credit Toon, and per his request, add his
+	email address.
+
+	* com.h (FFECOM_DETERMINE_TYPES): #include "config.j".
+
+	* config.j, convert.j, flags.j, hconfig.j, rtl.j, tconfig.j,
+	tm.j, tree.j: Don't #include if already done.
+
+	* convert.j: #include "tree.j" first, as convert.h clearly depends
+	on trees being defined.
+
+	* rtl.j: #include "config.j" first, since there's some stuff
+	in rtl.h that assumes it has been #included.
+
+	* tree.j: #include "config.j" first, or real.h makes inconsistent
+	decision about return type of ereal_atof, leading to bugs, and
+	because tree.h/real.h assume config.h already included.
+
+Wed Feb 15 14:40:20 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.5 released.

+	TCONFIG_H, TM_H, TREE_H): Update/new symbols.
+	(deps-kinda): More fixes wrt changing some .h to .j.
+	Document and explain this rule a bit better.
+	Accommodate changes in output of gcc -MM.
+
+	* *.h, *.c: Change #include's so proj.h not assumed to #include
+	malloc.h or config.h (now config.j), and so new .j files are
+	used instead of old .h ones.
+
+	* com.c (ffecom_init_0): Use FLOAT_TYPE_SIZE for f2c's
+	TYLONG/TYLOGICAL type codes, to get g77 working on Alpha.
+
+	* com.h: Make all f2c-related integral types "int", not "long
+	int".
+
+	* config.j, convert.j, flags.j, glimits.j, hconfig.j, rtl.j,
+	tconfig.j, tm.j, tree.j: New files wrapping around gbe
+	.h files.
+
+	* config.h, convert.h, flags.h, glimits.h, hconfig.h, rtl.h,
+	tconfig.h, tm.h, tree.h: Deleted so new .j files
+	can #include the gbe files directly, instead of using "../",
+	and thus do better with various kinds of builds.
+
+	* proj.h: Delete unused NO_STDDEF and related stuff.
+
+Tue Feb 14 08:28:08 1995  Craig Burley  (burley@gnu.ai.mit.edu)

+
+	* data.c (ffedata_gather_, ffedata_value_): Warn when about
+	to initialize a large aggregate area, due to design flaw resulting
+	in too much time/space used to handle such cases.
+	Use COMMON area name, and first notice of symbol, for multiple-

+	location.
+	(FFEDATA_sizeTOO_BIG_INIT_): New macro per above.
+
+Mon Feb 13 13:54:26 1995  Dave Love  <d.love@dl.ac.uk>
+
+	* Make-lang.in (F77_SRCS): Use $(srcdir)/f/proj.h.in, not
+	$(srcdir)/f/proj.h for build outside srcdir.
+
+Sun Feb 12 13:37:11 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* ../README.g77: Clarify procedures for unpacking, add asterisks
+	to mark important things the user must do.
+
+	* Fix dates in/add dates to ../README.g77, BUGS, CREDITS, DOC,
+	INSTALL, PROJECTS, README.
+
+Sun Feb 12 00:26:10 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* Version 0.5.4 released.
+
+	* Make-lang.in (f/proj.h): Reproduce this rule here from
+	Makefile.in.
+	($(srcdir)/f/conf-proj): Put autoconf's stdout in temp file

+
+	* Makefile.in ($(srcdir)/conf-proj): See Make-lang.in's similar
+	rule.
+
+Sat Feb 11 20:56:02 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* BUGS: Clarify some bugs.
+
+	* DOC: Many improvements and fixes.
+
+	* README: Move bulk of text, edited, to ../README.g77, and
+	replace with pointer to that file.
+
+	* com.c (ffecom_init_0): Comment out warning about sizeof(ftnlen)
+	as per ste.c change.  Add text about ASSIGN to help user understand
+	what is being warned about.
+
+	* conf-proj.in: Fix typos in comments.
+
+	* proj.h.in: Add ARRAY_ZERO_SIZE to parallel malloc.h's version,
+	in case it proves to be needed.
+
+	* ste.c: Comment out assertions requiring sizeof(ftnlen) >=
+	sizeof(char *), in the hopes that overflow will never happen.
+	(ffeste_R838): Change assertion to fatal() with at least
+	partially helpful message.
+
+Sat Feb 11 12:38:00 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* com.c (ffecom_vardesc_): Crash if typecode is -1.
+
+	* ste.c (ffeste_io_dolio_): Crash if typecode is -1.
+
+Sat Feb 11 09:51:57 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* ste.c: In I/O code tests for item arrayness, sort of revert
+	to much earlier code that tests original exp, but also check
+	in newer way just in case.  Newer way alone treated FOO(1:40)
+	as an array, not sure why older way alone didn't work, but I
+	think maybe it was when diagnosed code was involved, and
+	since there are now checks for error_mark_node, maybe the old
+	way alone would work.  But better to be safe; both original
+	ffebld exp _and_ the transformed tree must indicate an array
+	for the size-determination code to be used, else just 1/2 elements
+	assumed.  And this text is for EMACS: (foo at bar).
+
+Fri Feb 10 11:05:50 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* ste.c: In many cases, surround statement-expansion code
+	with ffecom_push_calltemps () and ffecom_pop_calltemps ()
+	so COMPLEX-returning functions can have temporaries pushed
+	in "auto-pop" mode and have them auto-popped at the end of
+	the statement.

+
+	* stc.c (ffestc_R501_item): Don't reset kind/where to NONE when
+	setting basictype/kindtype info for symbol, or especially
+	its function/result twin, because kind/where might not be NONE.

+
+	* Make-lang.in (include/f2c.h:): Set shell variable src more
+	robustly (independent of whether srcdir is relative or absolute).

+
+	* com.h: Extra ...SIZE stuff taken from com.c.
+
+	* com.c (FFECOM_DETERMINE_TYPES): Define before including com.h.
+	(BITS_PER_WORD etc.) Remove and use conditional definitions to com.h.
+
+	* runtime/configure.in: #define FFECOM_DETERMINE_TYPES for com.h in
+	f2c type determination.

+Fri Feb  3 20:33:14 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* g77.c (main): Treat -l like filename in terms of -x handling.
+	Rewrite arglist mechanism for ease of maintenance.
+	Make sure every -lf2c is followed by -lm and vice versa.
+
+	* Make-lang.in: Put complete list of sources in F77_SRCS def
+	so changing a .h file, for example, causes rebuild.
+
+	* Makefile.in: Change test for nextstep to m68k-next-nextstep* so
+	all versions of nextstep on m68k get the necessary flag.
+
+Fri Feb  3 19:10:32 1995  Dave Love  <d.love@dl.ac.uk>

+
+	* config-lang.in: Comment out more of f2c rules (c.f. Make-lang.in).
+	(This stuff is relevant iff you gave configure --enable-f2c.)
+	Create f/runtime directory tree iff not building in source
+	directory.
+
+	* Makefile.in (srcdir): Append slash so we get the right value when
+	not building in the source directory.  This is a consequence of not
+	building the `f' sources in `f'.

+
+	* g77.c: Avoid putting out useless "-xnone -xf77" pairs so
+	larger command lines can be accommodated.
+	Recognize both `-xlang' and `-x lang'.
+	Recognize `-xnone' and `-x none' to mean what it does, instead
+	of treating "none" as any other language.
+	Some minor, slight improvements in the way args are handled
+	(hopefully for clearer, more maintainable code), including
+	consistency checks on arg count just in case.
+
+Wed Jan 18 16:41:57 1995  Craig Burley  (burley@gnu.ai.mit.edu)
+
+	* DOC: Explain -fautomatic better.
+
+	* INSTALL: Describe libf2c.a better.
+
+	* Make-lang.in, Makefile.in: Build f771 &c with gcc/ as cd instead

+	to precisely match how they're declared in libf2c.
+
+	* com.h, com.c: Revise to more elegantly track related stuff
+	in the version of f2c.h used to build libf2c.
+
+	* com.c: Increase FFECOM_sizeMAXSTACKITEM, and if 0 or undefined
+	when checked to determine where to put entity, treat as infinite.
+	Rewrite temporary mechanism to be based on trees instead of
+	ffeinfo stuff, and make it much simpler.  Change interface
+	accordingly.
+	Fixes to better track types of things, make appropriate
+	conversions, etc.  E.g. when making an arg for a libf2c
+	function, make sure it's of the right type (such as ftnlen).
+	Delete opBACKEND transformation code.
+	(ffecom_init_0): Smoother initialization of types, especially
+	paying attention to using consistent rules for making INTEGER,
+	REAL, DOUBLE PRECISION, etc., and for deciding their "*N"
+	and kind values that will work across all g77 platforms.
+	No longer require per-target configuration info in target.h
+	or config/*/*; use new type module to store size, alignment.
+	(ffecom_member_phase2): Declare COMMON/EQUIVALENCE group members
+	so debugger sees them.
+	(ffecom_finish_progunit): Transform all symbols in program unit,
+	so -g will show they all exist.
+
+	* expr.c (ffeexpr_collapse_substr): Handle strange substring
+	range values.
+
+	* info.h, info.c: Provide connection to new type module.
+	Remove tests that yield compiler warnings.

+	* lex.c (ffelex_file_fixed): Remove redundant/buggy code.
+
+	* stc.c (ffestc_kindtype_kind_, ffestc_kindtype_star_): Replace
+	boring switch stmt with simple call to new type module.  This
+	sort of thing is a reason to get up in the morning.
+
+	* ste.c: Update to handle new interface for
+	ffecom_push/pop_tempvar.
+	Fixes to better track types of things.
+	Fixes to not crash for certain diagnosed constructs.
+	(ffeste_begin_iterdo_): Check only constants for overflow to avoid
+	spurious diagnostics.
+	Don't convert larger integer (say, INTEGER*8) to canonical integer
+	for iteration count.
+
+	* stw.h: Track DO iteration count temporary variable.
+
+	* symbol.c: Remove consistency tests that cause compiler warnings.

+	compiler warnings.
+	(ffetarget_convert_character1_typeless): Pick up length of
+	typeless type from new type module.
+
+	* target.h: Crash build if target float bit pattern cannot be
+	precisely determined.
+	Remove all the type cruft now determined by ffecom_init_0
+	at invocation time and maintained in new type module.
+	Put casts on second arg of all REAL_VALUE_TO_TARGET_DOUBLE
+	uses so compiler warnings avoided (requires target float bit
+	pattern to be precisely determined, hence code to crash build).
+
+	* top.c: Add inits/terminates for new type module.
+
+	* type.h, type.c: New module.
+
+	* gbe/2.6.2.diff: Remove all patches to files in gcc/config/
+	directory and its subdirectories.
