GNU M4 1.4.14 released (stable)

[Eric Blake]

The GNU M4 team is proud to announce the release of M4 1.4.14.  M4 is a
macro processing language, and among other uses, it is required by GNU
Autoconf for generating configure scripts.

This release fixes some corner case regressions introduced in previous
builds, and adds a number of portability improvements from gnulib.

For a summary of changes and contributors, see:
  http://git.sv.gnu.org/cgit/m4.git/log/?id=v1.4.14
or run this command from a git-cloned m4 directory:
  git shortlog v1.4.13..v1.4.14

To summarize the gnulib-related changes, run this command from a
git-cloned gnulib directory:
  git shortlog v0.0-2015-gf6778f8..v0.0-3478-g108cfb8

[*] You can use either of the above signature files to verify that
the corresponding file (without the .sig suffix) is intact.  First,
be sure to download both the .sig file and the corresponding tarball.
Then, run a command like this:

  gpg --verify m4-1.4.14.tar.gz.sig

If that command fails because you don't have the required public key,
then run this command to import it:

  gpg --keyserver keys.gnupg.net --recv-keys F4850180

and rerun the `gpg --verify' command.

This release was bootstrapped with the following tools:
  Autoconf 2.65
  Automake 1.11.1
  Gnulib v0.0-3478-g108cfb8

NEWS

* Noteworthy changes in Version 1.4.14 (2010-02-24) [stable]
  Released by Eric Blake, based on git version 1.4.13.*

** Fix regression introduced in 1.4.12 where executing with stdout closed
   could crash m4 on exit on some platforms.

** Fix regressions introduced in 1.4.13 in the `esyscmd' builtin, where
   closed file descriptors could interfere with child execution, and where
   a child status of 127 made m4 print a spurious message to stderr.

** Fix a security hole in 'make dist', present since at least M4 1.4, that
   could affect anybody attempting to redistribute modified sources (see
   Automake CVE-2009-4029).

** A number of portability improvements inherited from gnulib.
