+[This file contains two alternative recipes for compiling X11 with GCC.
+The first alternative puts libgcc.a into the shared X library; the second
+does not.  Neither alternative works on all kinds of systems.
+It may be that when using GCC 2.4, both alternatives work okay on 
+relatively recent Sparc systems.  The first alternative is likely
+not to work on a Sun 3 without hardware floating point.]
+
+How to compile X11R5 (patch level 11) with GCC version 2:
+
+The patches include support for building the shared libraries with GCC
+2 on the Sparc and 68k machines.  This version includes the necessary
+parts of libgcc.a in the shared library for X, in case functions in
+that library need it.  Thus the default behavior is now to build
+everything, including the libraries, with gcc.
+
+If you build the shared library this way, it may not work with 
+executables made with older versions of GCC (2.3.3 and earlier).
+If that happens, relink those executables with the latest GCC.
+IF YOU THINK YOU MIGHT COMPILE X FOR SOLARIS 2, then you really don't
+need this patch: get /contrib/R5.SunOS5.patch.tar.Z from
+export.lcs.mit.edu instead.  It has everything you need to do the
+build for Solaris 2, sets you up to everything with GCC, and is
+backward compatible with Sunos 4.*.  Get the the README
+(/contrib/R5.SunOS5.patch.README at export) for more info.
+
+If you see undefined symbols _dlopen, _dlsym, or _dlclose when linking
+with -lX11, compile and link against the file mit/util/misc/dlsym.c in
+the MIT X11R5 distribution.  Alternatively, do dynamic linking
+by using a non-GNU ld.
+
+mit/config/Imake.tmpl -- Do not set -fstrength-reduce if we have GCC 2.
+If -fstrength-reduce (or any other -f option) is a major win, then it
+will most likely be turned on by -O2 optimization.
+
+mit/config/sunLib.rules -- If HasGcc and GccVersion > 1 are true, then
+use gcc -fpic to generate PIC code.  Make sure that gcc does not use
+gas (the GNU assembler) when compiling PIC code; gas does not assemble
+it correctly.
+
+***If you have gas installed where gcc uses it by default, you might have
+to add -B/bin/ to the PositionIndependentCFlags.***

+[This is the older version]
+
+How to compile X11R5 (patch level 11) with GCC version 2:
+
+The patches include support for building the shared libraries with GCC 2 on 
+the Sparc and 68k machines.
+
+NOTE: Such shared libraries built with GCC version 2.3 DID NOT WORK
+with executables previously linked using Sun CC!  This is because
+neither those executables nor the gcc-compiled shared libraries contain
+libgcc.a.  The shared libraries did work with executables linked using
+GCC (running the Sun linker, of course) because GCC tells the linker to
+link in libgcc.a.  Because of these limitations the default behavior is
+to NOT build the shared libraries with gcc.
+
+Changes in GCC 2.4 seem to have eliminated the problem, and such a
+shared library now seems work with all executables.  If you want the
+gcc-compiled shared libraries turn on "Gcc2BuildLibs" in site.def.  If
+you try this, please tell bug-gcc@prep.ai.mit.edu whether it works.
+
+Sun forgot to include a static version of libdl.a with some versions
+of SunOS (4.1 mainly).  If you see undefined symbols _dlopen, _dlsym,
+or _dlclose when linking with -lX11, compile and link against the file
+mit/util/misc/dlsym.c in the MIT X11R5 distribution.
