Subject:	ANNOUNCE: DJGPP port of GNU Diffutils 2.9 uploaded.
Date:	Sun, 7 Mar 2010 17:20:22 +0100

This is a port of GNU Diffutils version 2.9 to MSDOS/DJGPP.

  Diffutils are a collection of programs for finding differences
  between files:

    * diff  -- displays differences between 2 files line by line;

    * diff3 -- displays differences between 3 files (usually, 2 files
               and their common ancestor);

    * sdiff -- displays differences between 2 files side by side, and
               allows to merge between them interactively;

    * cmp   -- displays differences between 2 binary files byte by byte.

  The documentation of the package includes, in addition to the four
  programs mentioned above, also the manual for the Patch utility.


  DJGPP specific changes.
  =======================

  - There are four fixes of bugs that only appear if the sources are compiled
    on systems that popen/pclose instead of fork and pipe.  A patch submited to
    the maintainers has already found its way into the official sources.
  - This port will detect at runtime if it is running on an OS with LFN or not
    and choose the appropriate temp file name pattern accordingly.
    E.g.: "sdiffXXXXXX" if LFN support is available, else "dfXXXXXX" will be
    used.
  - This port will honor also the DOS specific environment variable TEMP and
    TMP if TMPDIR is not set.  If neither is accessible then P_tmpdir will
    define the location to store temp files.
  - All other changes are those required to get gnulib sources compiled with
    djgpp and are not user visible.

  To build this port you will need:
  - to have an OS with LFN support to configure and compile the source
    package.  I have no plans to support SFN systems to build the diffutils
    binaries.
  - if you use djdev204 you will have to adjust your /dev/env/DJDIR/include/time.h.
    _rdtsc declaration and definition both needs static as qualifier and the
    extern qualifier removed from the declaration.

  As usual, all djgpp specific files (config.bat, diffs, README files, etc.)
  are located in the /djgpp subdir.

  The port has been configured, compiled and tested on a WinXP Prof SP3 system
  with LFN support using stock djdev203/djdev204, gcc442 and bsh205bbr3.  LFN
  support is required due to SFN file name conflicts that I have not resolved.

  Please note that the testsuite does not work at all.  This is not a port issue.
  No testsuite generated with autoconf 2.65.35 or later works with djgpp.
  I still have not figured out if this is a bash  or a make issue.

  Please also note that there is a /ms directory that contains files that are
  part of the official FSF diffutils distribution.  I have inspected those files
  but I have never used them nor I have plans to change this in the future.
  Due to the massive use of gnulib code it is no longer possible to compile the
  official FSF distribution out-of-the-box.  So I will neither try to use those
  files nor to keep them up to date.  I will only use my own ones.  If someone
  else would like to keep those files up to date it will be ok with me.

  For futher information about GNU m4 please read the info docs and NEWS file.
