GNU Autoconf 2.67 released [stable]

[Eric Blake]

The GNU Autoconf team is pleased to announce the stable release of
Autoconf 2.67.  Autoconf is an extensible package of M4 macros that
produce shell scripts to automatically configure software source code
packages.  These scripts can adapt the packages to many kinds of
UNIX-like systems without manual user intervention.  Autoconf creates a
configuration script for a package from a template file that lists the
operating system features that the package can use, in the form of M4
macro calls.

This release fixes a few regressions introduced in the previous release,
and is primarily focused on bug fixes.  It also includes a few new
features, documented below.

[*] 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 autoconf-2.67.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 2527436A

and rerun the `gpg --verify' command.

This release was bootstrapped with the following tools:
  Automake 1.11.1

./NEWS

* Major changes in Autoconf 2.67 (2010-07-21) [stable]
  Released by Eric Blake, based on git versions 2.66.*.

** AC_CONFIG_SUBDIRS with more than one subdirectory at a time works again.
   Regression introduced in 2.66.

** AC_CHECK_SIZEOF of a pointer type works again.  Regression introduced in
   2.66.

** New macro AC_FC_LINE_LENGTH to accept long Fortran source code lines.

** AC_PREPROC_IFELSE now keeps the preprocessed output in the conftest.i
   file for inspection by the commands in the ACTION-IF-TRUE argument.

** AC_INIT again allows parentheses and other characters that are literal
   in single- or double-quoted strings, and in quoted and unquoted
   here-documents, for its PACKAGE and VERSION arguments.  Regression
   introduced in 2.66.

** autoreconf passes warning flags to new enough versions of aclocal.

** Running an Autotest testsuite in parallel mode no longer triggers a
   race condition that could cause the testsuite run to end early,
   fixing a sporadic failure in autoconf's own testsuite.  Bug present
   since introduction of parallel tests in 2.63b.
