Major changes in Autoconf 2.61 (2006-11-17)
=======================================================
** New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.
** AC_ARG_ENABLE and AC_ARG_WITH now allow '.' in feature and package
    names.

** BIN_SH
    Autoconf-generated shell scripts no longer export BIN_SH, due to
    configuration hassles with this.  Installers who need BIN_SH in
    their environment should set it before invoking 'configure' and
    'make'.  As far as we know, this affects only Unixware installations.

** Obsolescent macros
    The documentation now says that the following macros are obsolescent,
    as they are superseded by Gnulib:
       AC_FUNC_FNMATCH  AC_FUNC_FNMATCH_GNU
       AC_FUNC_GETLOADVG  AC_REPLACE_FNMATCH

    New programs should use the Gnulib counterparts of these macros.
    We have no current plans to remove them from Autoconf.

** AC_COMPUTE_INT no longer caches or reports results.
** AC_CHECK_DECL now also works with aggregate objects.
** AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
    NonStop platforms.
** GNU M4 1.4.7 or later is now recommended.
** m4_maketemp
    Now an alias for m4_mkstemp.
** The check for C99 now tests for varargs macros, as documented.
    It also tests that the preprocessor supports 64-bit integers.
** Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H" rather than
    "#if HAVE_STDLIB_H", so that it now works with "gcc -Wundef -Werror".
** The functionality of the undocumented _AC_COMPUTE_INT is now provided
    by a public and documented macro, AC_COMPUTE_INT.  The parameters to
    the two macros are different, so autoupdate will not change the old
    private name to the new one.  _AC_COMPUTE_INT may be removed in
    a future release.
** AC_TYPE_LONG_LONG_INT and AC_TYPE_UNSIGNED_LONG_LONG_INT now require
    that long long types be at least 64 bits wide, as C99 and tradition
    requires.  Formerly, they accepted implementations of any width.
