 1.:     DJGPP specific changes.

-        =======================
-
-        The DJGPP port of Bison offers LFN and SFN support depending on which
-        OS it is running. If LFN support is available or not is determinated at
-        run time.  If LFN support is available (DOS session under Win9X), the
-        standard posix file name extensions will be used.  These are: y.tab.c,
-        y.tab.c++, y.tab.h, y.output, etc.  If only SFN support is available
-        (plain DOS), then the standard MSDOS short file names will be used.
-        These are: y_tab.c, y_tab.h, y.out, etc.
-        It should be noticed that this bison version needs the m4 program as
-        back end to generate the parser file (y.tab.c etc.) from the skeleton
-        files.  This implies that m4 must always be installed to get bison
-        working.  m4 will use a couple of m4 scripts that will be installed in
-        /dev/env/DJDIR/share/bison and shall not be removed.
-        It should also be noticed that the skeleton files bison.simple and
-        bison.hairy are no longer supported.  This applies also to the environ-
-        ment variables BISON_HAIRY and BISON_SIMPLE. Those variables are *no*
-        longer honored at all.
-        The kind of skeleton file bison.hairy is no longer supported at all.
-        The skeleton file bison.simple is now called yacc.c and is an m4 script.
-        The other two skeleton files supported by this bison version are glr.c
-        and lalr1.cc.  The first one is a generalized LR C parser based on
-        Bison's LALR(1) tables and the second one is a experimental C++ parser
-        class.
-        As has been told before, bison uses m4 to generate the parser file.
-        This is done by forking and using pipes for the IPC.  MSDOS does not
-        support this functionality so this has been reproduced in the usual
-        way by redirecting stdin and stdout of bison and m4 to temporary files
-        and processing these files in sequence.  All the changes to the sources
-        are documented in the djgpp/diffs file.
-
-        Please **read** the docs.

+       not cleanly map to 8.3 file names, you will need an OS with LFN support
+       to configure and compile the sources. On Win98 this implies that the
+       generation of numeric tails for 8.3 file name aliases must be enabled
+       or the compilation will fail.

 3.2.:   Source distributions downloaded from one of the GNU FTP sites need

-        some more work to unpack, if LFN support is not available.  If LFN is
-        available then you can extract the source files from the archive with
-        any unzip program and proceed to the paragraph 3.3, below.  Any file
-        name issue will be handled by the the DJGPP configuration files.
-        To unpack the source distribution on SFN systems, first, you MUST use
-        the `djunpack' batch file to unzip the package.  That is because some
-        file names in the official distributions need to be changed to avoid
-        problems on the various platforms supported by DJGPP.
-        `djunpack' invokes the `djtar' program (that is part of the basic DJGPP
-        development kit) to rename these files on the fly given a file with
-        name mappings; the distribution includes a file `djgpp/fnchange.lst'
-        with the necessary mappings.  So you need first to retrieve that batch
-        file, and then invoke it to unpack the distribution.  Here's how:
-
-          djtar -x -p -o bison-2.1/djgpp/djunpack.bat bison-2.1.tar.gz > djunpack.bat
-          djunpack bison-2.1.tar.gz
-
-        (The name of the distribution archive and the leading directory of the
-        path to `djunpack.bat' in the distribution will be different for
-        versions of Bison other than 2.1.)
-
-        If the argument to `djunpack.bat' include leading directories, it MUST
-        be given with the DOS-style backslashes; Unix-style forward slashes
-        will NOT work.
-
-        If the distribution comes as a .tar.bz2 archive, and your version of
-        `djtar' doesn't support bzip2 decompression, you need to unpack it as
-        follows:
-
-          bnzip2 bison-2.1.tar.bz2
-          djtar -x -p -o bison-2.1/djgpp/djunpack.bat bison-2.1.tar > djunpack.bat
-          djunpack bison-2.1.tar
+       some more work to unpack, if LFN support is not available.  If LFN is

+         djunpack bison-@VERSION@.tar.gz
+
+       (The name of the distribution archive and the leading directory of the
+       path to `djunpack.bat' in the distribution will be different for
+       versions of Bison other than @VERSION@.)
+
+       If the argument to `djunpack.bat' include leading directories, it MUST
+       be given with the DOS-style backslashes; Unix-style forward slashes
+       will NOT work.
