-=head1 NAME
-
-perldos - Perl under DOS, W31, W95.
-
-=head1 SYNOPSIS
-
-These are instructions for building Perl under DOS (or w??), using
-DJGPP v2.03 or later.  Under w95 long filenames are supported.
-
-=head1 DESCRIPTION
-
-Before you start, you should glance through the README file
-found in the top-level directory where the Perl distribution
-was extracted.  Make sure you read and understand the terms under
-which this software is being distributed.
-
-This port currently supports MakeMaker (the set of modules that
-is used to build extensions to perl).  Therefore, you should be
-able to build and install most extensions found in the CPAN sites.
-
-Detailed instructions on how to build and install perl extension
-modules, including XS-type modules, is included.  See 'BUILDING AND
-INSTALLING MODULES'.

-=item DJGPP
-
-DJGPP is a port of GNU C/C++ compiler and development tools to 32-bit,
-protected-mode environment on Intel 32-bit CPUs running MS-DOS and compatible
-operating systems, by DJ Delorie <dj@delorie.com> and friends.
-
-For more details (FAQ), check out the home of DJGPP at:
-
-        http://www.delorie.com/djgpp/
-
-If you have questions about DJGPP, try posting to the DJGPP newsgroup:
-comp.os.msdos.djgpp, or use the email gateway djgpp@delorie.com.
-
-You can find the full DJGPP distribution on any of the mirrors listed here:
-
-        http://www.delorie.com/djgpp/getting.html
-
-You need the following files to build perl (or add new modules):

-
-Unpack the source package F<perl5.8*.tar.gz> with djtarx. If you want
-to use long file names under w95 and also to get Perl to pass all its
-tests, don't forget to use
-
-        set LFN=y
-        set FNCASE=y
-
-before unpacking the archive.
-
-=item *
-
-Create a "symlink" or copy your bash.exe to sh.exe in your C<($DJDIR)/bin>
-directory.
-
-        ln -s bash.exe sh.exe
-
-[If you have the recommended version of bash for DJGPP, this is already
-done for you.]
-
-And make the C<SHELL> environment variable point to this F<sh.exe>:
-
-        set SHELL=c:/djgpp/bin/sh.exe (use full path name!)
-
-You can do this in F<djgpp.env> too. Add this line BEFORE any section
-definition:
-
-        +SHELL=%DJDIR%/bin/sh.exe
-
-=item *
-
-If you have F<split.exe> and F<gsplit.exe> in your path, then rename 
-F<split.exe> to F<djsplit.exe>, and F<gsplit.exe> to F<split.exe>.
-Copy or link F<gecho.exe> to F<echo.exe> if you don't have F<echo.exe>.
-Copy or link F<gawk.exe> to F<awk.exe> if you don't have F<awk.exe>.
-
-[If you have the recommended versions of djdev, shell utilities and
-gawk, all these are already done for you, and you will not need to do
-anything.]
-
-=item *
-
-Chdir to the djgpp subdirectory of perl toplevel and type the following
-commands:
-
-        set FNCASE=y
-        configure.bat
-
-This will do some preprocessing then run the Configure script for you.
-The Configure script is interactive, but in most cases you just need to
-press ENTER.  The "set" command ensures that DJGPP preserves the letter
-case of file names when reading directories.  If you already issued this
-set command when unpacking the archive, and you are in the same DOS
-session as when you unpacked the archive, you don't have to issue the
-set command again.  This command is necessary *before* you start to 
-(re)configure or (re)build perl in order to ensure both that perl builds 
-correctly and that building XS-type modules can succeed.  See the DJGPP 
-info entry for "_preserve_fncase" for more information:
-
-        info libc alphabetical _preserve_fncase
-
-If the script says that your package is incomplete, and asks whether
-to continue, just answer with Y (this can only happen if you don't use
-long filenames or forget to issue "set FNCASE=y" first).
-
-When Configure asks about the extensions, I suggest IO and Fcntl,
-and if you want database handling then SDBM_File or GDBM_File
-(you need to install gdbm for this one). If you want to use the
-POSIX extension (this is the default), make sure that the stack
-size of your F<cc1.exe> is at least 512kbyte (you can check this
-with: C<stubedit cc1.exe>).
-
-You can use the Configure script in non-interactive mode too.
-When I built my F<perl.exe>, I used something like this:
-
-        configure.bat -des
-
-You can find more info about Configure's command line switches in
-the F<INSTALL> file.
-
-When the script ends, and you want to change some values in the
-generated F<config.sh> file, then run
-
-        sh Configure -S
-
-after you made your modifications.
-
-IMPORTANT: if you use this C<-S> switch, be sure to delete the CONFIG
-environment variable before running the script:
-
-        set CONFIG=
-

-Now you can compile Perl. Type:

-
-=head2 Testing Perl on DOS
-
-Type:
-
-        make test
-
-If you're lucky you should see "All tests successful". But there can be
-a few failed subtests (less than 5 hopefully) depending on some external
-conditions (e.g. some subtests fail under linux/dosemu or plain dos
-with short filenames only).
-
-=head2 Installation of Perl on DOS
-
-Type:
-
-        make install
-
-This will copy the newly compiled perl and libraries into your DJGPP
-directory structure. Perl.exe and the utilities go into C<($DJDIR)/bin>,
-and the library goes under C<($DJDIR)/lib/perl5>. The pod documentation
-goes under C<($DJDIR)/lib/perl5/pod>.
-
-=head1 BUILDING AND INSTALLING MODULES ON DOS
-
-=head2 Building Prerequisites for Perl on DOS
-
-For building and installing non-XS modules, all you need is a working
-perl under DJGPP.  Non-XS modules do not require re-linking the perl
-binary, and so are simpler to build and install.
-
-XS-type modules do require re-linking the perl binary, because part of
-an XS module is written in "C", and has to be linked together with the
-perl binary to be executed.  This is required because perl under DJGPP
-is built with the "static link" option, due to the lack of "dynamic
-linking" in the DJGPP environment.
-
-Because XS modules require re-linking of the perl binary, you need both
-the perl binary distribution and the perl source distribution to build
-an XS extension module.  In addition, you will have to have built your
-perl binary from the source distribution so that all of the components
-of the perl binary are available for the required link step.
-
-=head2 Unpacking CPAN Modules on DOS
-
-First, download the module package from CPAN (e.g., the "Comma Separated
-Value" text package, Text-CSV-0.01.tar.gz).  Then expand the contents of
-the package into some location on your disk.  Most CPAN modules are
-built with an internal directory structure, so it is usually safe to
-expand it in the root of your DJGPP installation.  Some people prefer to
-locate source trees under /usr/src (i.e., C<($DJDIR)/usr/src>), but you may
-put it wherever seems most logical to you, *EXCEPT* under the same
-directory as your perl source code.  There are special rules that apply
-to modules which live in the perl source tree that do not apply to most
-of the modules in CPAN.
-
-Unlike other DJGPP packages, which are normal "zip" files, most CPAN
-module packages are "gzipped tarballs".  Recent versions of WinZip will
-safely unpack and expand them, *UNLESS* they have zero-length files.  It
-is a known WinZip bug (as of v7.0) that it will not extract zero-length
-files.
-
-From the command line, you can use the djtar utility provided with DJGPP
-to unpack and expand these files.  For example:
-
-        C:\djgpp>djtarx -v Text-CSV-0.01.tar.gz
-
-This will create the new directory C<($DJDIR)/Text-CSV-0.01>, filling
-it with the source for this module.
-
-=head2 Building Non-XS Modules on DOS
-
-To build a non-XS module, you can use the standard module-building
-instructions distributed with perl modules.
-
-    perl Makefile.PL
-    make
-    make test
-    make install
-
-This is sufficient because non-XS modules install only ".pm" files and
-(sometimes) pod and/or man documentation.  No re-linking of the perl
-binary is needed to build, install or use non-XS modules.
-
-=head2 Building XS Modules on DOS
-
-To build an XS module, you must use the standard module-building
-instructions distributed with perl modules *PLUS* three extra
-instructions specific to the DJGPP "static link" build environment.
-
-    set FNCASE=y
-    perl Makefile.PL
-    make
-    make perl
-    make test
-    make -f Makefile.aperl inst_perl MAP_TARGET=perl.exe
-    make install
-
-The first extra instruction sets DJGPP's FNCASE environment variable so
-that the new perl binary which you must build for an XS-type module will
-build correctly.  The second extra instruction re-builds the perl binary
-in your module directory before you run "make test", so that you are
-testing with the new module code you built with "make".  The third extra
-instruction installs the perl binary from your module directory into the
-standard DJGPP binary directory, C<($DJDIR)/bin>, replacing your
-previous perl binary.
-
-Note that the MAP_TARGET value *must* have the ".exe" extension or you
-will not create a "perl.exe" to replace the one in C<($DJDIR)/bin>.
-
-When you are done, the XS-module install process will have added information
-to your "perllocal" information telling that the perl binary has been replaced,
-and what module was installed.  You can view this information at any time
-by using the command:
-
-        perl -S perldoc perllocal

+

+The latest version is 3.5, released in Feb 98.

+

+3. Add C<RAND_SWITCH> or C<MUTEX_SWITCH> or C<RR_SWITCH> to C<CFLAGS>

+in the F<makefile>. Note that using these values, multithreading will

+NOT be preemptive. This is necessary, since djgpp's libc is not thread safe.

+

+=item 

+

+4. Apply the following patch:

+

+    *** include/pthread/signal.h~	Wed Feb  4 10:51:24 1998

+    --- include/pthread/signal.h	Tue Feb 10 22:40:32 1998

+

+=item

+

+5. run make (before you do this, you must make sure your C<SHELL> environment 

+variable does NOT point to bash).

+
