This is a port of GNU m4 1.4.17 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.
=======================
- This is the first port that has been compiled using djdev205. Starting
with this port version I will no longer support neither djdev204 nor djdev203.
- The port has been configured and compiled on WinXP SP3. There is no guarantee
that this may be possible with any other DOS-like OS. Due to the massive use
of long file names it will not be possible to configure and compile without
LFN support. The port has been compiled using gcc510 and bnu225br2.
- The port has been tested by using it. I have used them only on WinXP.
It has worked flawlessly. I do not konw if this will ever be the case on
FreeDOS. I have never used/tested them in that environment.
- 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 determinated 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 an OS with LFN support to configure and
compile the source package.
The test case 198.sysval will be skipped because DJGPP/DOS does not provide
a kill command. This is *not* a bug of the port.
As usual, all djgpp specific files (diffs, README files, etc.) are stored in
the /djgpp directory. The sources have been configured to be build in the
/_build.205 directory. If for some reason it does not work for you, delete
it contents and configure from scratch again.
For further information about GNU m4 please read the info docs and NEWS file.
This is an verbatim extract of the NEWS file:
-------------------------------------------------------------------------------
* Noteworthy changes in release 1.4.17 (2013-09-22) [stable]
** Fix compilation with newer glibc headers.
** Fix a failure with diverting large amounts of text on mingw (does
not affect platforms that can rename an open file).
** A number of portability improvements inherited from gnulib.
* Noteworthy changes in release 1.4.16 (2011-03-01) [stable]
** Fix regressions in the `index' builtin. On glibc platforms, this
avoids false positives from a strstr bug in glibc 2.9 through 2.12;
on many other platforms, it fixes two separate regressions, a false
positive introduced in 1.4.11 and a false negative in 1.4.15.
** A number of portability improvements inherited from gnulib.
