./devel/m4, GNU version of UNIX m4 macro language processor

Branch: pkgsrc-2008Q1, Version: 1.4.11, Package name: m4-1.4.11, Maintainer: pkgsrc-users

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 builtin functions for including files, running
shell commands, doing arithmetic, etc. Autoconf needs GNU `m4' for
generating `configure' scripts, but not for running them.

GNU `m4' was originally written by Rene Seindal, with subsequent
changes by Franc,ois Pinard and other volunteers on the Internet. All
names and email addresses can be found in the file `THANKS' from the
GNU `m4' distribution.

This is release 1.4. It is now to be considered stable, future
releases are only meant to fix bugs, increase speed, or improve
documentation. However...

An experimental feature, which would improve `m4' usefulness, allows
for changing the syntax for what is a "word" in `m4'. You should use:
./configure --enable-changeword

if you want this feature compiled in. The current implementation slows
down `m4' considerably and is hardly acceptable. So, it might go away,
do not count on it yet.

   Update to 1.4.11:

   * Noteworthy changes in Version 1.4.11 (2008-04-02) [stable]
     Released by Eric Blake, based on git version 1.4.10a

   ** Security fixes for the -F option, for bugs present since -F was
      introduced in 1.3: Avoid core dump with 'm4 -F file -t undefined', and
      avoid arbitrary code execution with certain file names.

   ** Fix regression introduced in 1.4.9b in the `divert' builtin when more
      than 512 kibibytes are saved in diversions on platforms like NetBSD
      or darwin where fopen(name,"a+") seeks to the end of the file.

   ** The output of the `maketemp' and `mkstemp' builtins is now quoted if a
      file was created.  This is a minor security fix, because it was possible
      (although rather unlikely) that an unquoted string could match an
      existing macro name, such that use of the `mkstemp' output would trigger
      inadvertent macro expansion and operate on the wrong file name.

   ** Enhance the `defn' builtin to support concatenation of multiple text
      arguments, as required by POSIX.  However, at this time, it is not
      possible to concatenate a builtin macro with anything else; a warning is
      now issued if this is attempted, although a future version of M4 may
      lift this restriction to match other implementations.

   ** Enhance the `format' builtin to parse all C99 floating point numbers,
      even on platforms where strtod(3) is buggy, although the replacement
      function does have the known issue of rounding errors when parsing
      some decimal floating point values.  This fixes testsuite failures
      introduced in 1.4.9b.

   ** Enhance the `index' builtin to guarantee linear behavior, in spite of
      the surprisingly large number of systems with a brain-dead quadratic
      strstr(3).

   ** A number of portability improvements inherited from gnulib.
