Subject:	ANNOUNCE: DJGPP port of GNU m4 1.4.15 uploaded.
Date:	Fri, 3 Sep 2010 00:23:24 +0200

This is a port of GNU m4 1.4.15 to MSDOS/DJGPP.

  GNU m4 is an implementation of the traditional Unix macro processor.
  It is mostly SVR4 compatible, although it has some extensions (for example,
  handling more than 9 positional parameters to macros).  m4 also has built-in
  functions for including files, running shell commands, doing arithmetic, etc.


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

  - The port honors the value of the PATH_SEPARATOR environment variable
    to decide if colon or semicolon shall be used as path separator for
    the M4PATH environment variable.  If PATH_SEPARATOR is not set then
    semicolon will be used as path separator.

  - The port will also honor the value of the TMP and the TEMP environment
    variables to determinate where to store temporary files if TMPDIR is not
    set.  If neither of the three environment variables are set or if they
    point to not existing directories the value of P_tmpdir will be used.
    If this directory is also not accessible the current working directory
    will be used.

  - The port defines two new macros to identify the platform m4 is running
    on.  These are "__djgpp__" and "__msdos__" and "djgpp" and "msdos" if
    the -G option is specified.

  - The port assumes that a bash compatible shell is installed to be used by
    the m4 commands syscmd and esyscmd to execute the commands passed.  The
    shell to be used is defined at compile time by the value of "with_syscmd_shell"
    variable defined in the distributed config.site.  The current value is
    "/dev/env/DJDIR/bin/sh".  If the variable is not set then COMMAND.COM
    will be used as default shell for these two commands.  Because most of
    the executed scripts are UNIX centric it is not recommended to use
    COMMAND.COM and always to install the newest version of DJGPP's port of
    bash.  This port has been configured and compiled to use bash.

  To build this port you will need:
  - to install lsupp64a.zip or later
  - 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.
  - 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 m4
    binaries.

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


  The port has been configured, compiled and tested on a WinXP Prof SP3 system
  with LFN support using stock djdev203/djdev204, gcc444 and bsh205bbr3.  LFN
  support is required due to SFN file name conflicts in that I have not resolved.

  The test case 196.sysval will fail and the failure is expected to happen due
  to the missing of the kill command and it is *not* a bug of the port.

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



  The port consists of the usual three packages that have been compiled
  using stock djdev203 and that can be downloaded from ftp.delorie.com
  and mirrors as (time stamp 2010-09-02):

  are also distributed and can be downloaded from ftp.delorie.com and
  mirrors as (time stamp 2010-09-02):
