NEWS:

** Documentation

- AC_CHECK_HEADER, AC_CHECK_HEADERS
  More information on proper use.

** autoreconf

- Is more robust to different Gettext installations.

- Produces messages (when --verbose) to be understood by Emacs'
  compile mode.

** Obsolete options
  Support for the obsoleted options -m, --macrodir, -l, --localdir is
  dropped in favor of the safer --include/--prepend-include scheme.

** Customization

- ~/.autom4te.cfg makes it possible to disable the caching mechanism
  (autom4te.cache).  See `Customizing autom4te' in the documentation.

** Macros

- New macros
  AC_FUNC_MBRTOWC, AC_HEADER_STDBOOL.

- Obsoleted
  Obsoleted macros are kept for Autoconf backward compatibility, but
  should be avoided in configure.ac.  Running autoupdate is advised.
  AC_DECL_SYS_SIGLIST.

** Bug Fixes

- Portability of the Autoconf package to Solaris.

- Spurious warnings caused by config.status.
  This bug is benign, but painful: on some systems (typically
  FreeBSD), warnings such as:

     config.status: creating Makefile
     mv: Makefile: set owner/group (was: 1357/0): Operation not permitted

  could be issued.  This is fixed.

- Parallel Builds
  Simultaneous executions of config.status are possible again.

- Precious variables accumulation

  config.status could stack several copies of the precious variables
  assignments.


** Plans for 2.56

- ./configure <host>

  The compatibility hooks with the old scheme will be completely
  removed.  Please, advice/use `--build', `--host', and `--target'
  only.

- AC_CHECK_HEADER, AC_CHECK_HEADERS

  The tests will be stricter, please make sure your invocations are
  valid.

- shell functions

  Shell functions will gradually be introduced, probably starting with
  Autotest.  If you know machines which are in use that you suspect
  *not* to support shell functions, please run the test suite of
  Autoconf 2.55 on it, and report the results to
  bug-autoconf@gnu.org.

	Reported by Alexandre Duret-Lutz.

	* bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

	aclocal invocation, as Gettext macros might not be visible to

	Instead of blindly running autopoint, scan configure.ac (not the
	traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
	Reported by Paul D. Smith.

2002-10-08  Paul Eggert  <eggert@twinsun.com>

	Work around problems found when POSIXLY_CORRECT=1 is set.

	* lib/autoconf/programs.m4: here.
	* lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)
	(ETAGS_FOR_AUTOCONF): New.
	Use it.

2002-09-28  Akim Demaille  <akim@epita.fr>

	* lib/autoscan/functions, lib/autoscan/headers,
