+       Version 2.57.
+
+       * NEWS, configure.ac: Update version.
+
+       * doc/fdl.texi: Upgrade to FDL version 1.2.
+
+       * bin/autom4te.in (handle_traces): [^ *\(.*\) *$] ->
+       [^ *\(.*[^ ]\)? *].  The old regular expression was obviously wrong,
+       and it blunders into a GNU m4 bug as noted by Martin Frydl in
+       <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>.
+
+       * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
+       nontrivially in main's body, so that f's external declaration is
+       not optimized away in AIX.  This should fix the bug reported by
+       Martin Frydl in
+       <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
+
+       * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
+       _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
+       defined, to support freestanding compilers.  This should fix the
+       bug reported by Momchil Velkov in
+       <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
+
+       * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
+       arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
+       obsolete AC_CHECK_TYPE.  The missing empty arg was reported
+       by Simon Josefsson in
+       <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
+
+       * Makefile.maint (www-gnu): New macro.
+       (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
+       the location has moved.
