Autoconf 2.53a is released

[Akim Demaille <akim at epita dot fr>]

Some bugs were found in 2.53, hence 2.54 will be released shortly.  In
addition, as Darwin is now more popular, addressing its portability
issues has become a requirement for Autoconf.

This prerelease reflects faithfully the next release.  Please, try it
exhaustively, so that we can soon release a good Autoconf 2.54.
Trying Autoconf also includes *using* 2.53a to make a beta of your
package, and have this beta tested.

Thanks!

NEWS:

** Executables

- autoreconf is adjusted to GNU Gettext 0.11.

** Macros

- AC_PROG_CC_STDC is integrated into AC_PROG_CC.

** Bug fixes

- Spurious complaints from `m4_bmatch' about invalid regular
  expressions are suppressed.

- Empty top_builddirs are properly handled.

- AC_PATH_PROG
  Now colon in the optional path arguments are properly handled.

** Improved Zsh portability
  Both Autoconf the package, and the scripts it produces, should run
  more reliably with Zsh.  Bear in mind it is the default Bourne shell
  on Darwin.

** Documentation

- Limitations of Make
  More of them.

2002-04-22  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Pretty Help Strings): Remove a spurious
	comma.
	Reported by Gregory Giannoni.

2002-04-22  Akim Demaille  <akim@epita.fr>

	* tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
	Fixes false failures on Darwin.

2002-04-21  Paul Eggert  <eggert@twinsun.com>

	* TODO, bin/autoupdate.in, doc/autoconf.texi,
	lib/autoconf/general.m4, lib/autoconf/libs.m4,
	lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

	ZSH_VERSION fixes.  Bug reported by Raja R Harinath.

	* tests/atgeneral.m4 (AT_INIT): Likewise.

2002-04-19  Paul Eggert  <eggert@twinsun.com>

	* NEWS, TODO, bin/autom4te.in, bin/autoreconf.in, bin/autoupdate.in,
	doc/autoconf.texi, lib/freeze.mk, lib/Autom4te/Struct.pm,
	lib/autoconf/autoheader.m4, lib/autoconf/c.m4,

	* doc/autoconf.texi: Follow the outline suggested in the GNU
	Sample Texts sections of the Texinfo 4.2 manual.  Most

	the manual now.

	Fix some bugs when using "$@" when there might be zero positional
	arguments in cases where this matters.

	* bin/autoconf.as: Rewrite so that the problem does not come up.

	that is not portable to Zsh.

2002-04-19  Alexandre Duret-Lutz  <duret_g@epita.fr>

	* bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

	(AS_INIT): Invoke AS_SHELL_SANITIZE.
	* tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.

	Adjust Autoconf and Autotest.

	* lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
	AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
	* lib/autotest/general.m4 (AT_INIT): Likewise.
	* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
	Invoke _AS_PREPARE (not AS_PREPARE) in addition to
	AS_SHELL_SANITIZE.

	Use this M4sh to generate Autoconf's shell scripts.

	* tests/wrapsh.as: New, precursor of wrapsh.in.
	* tests/Makefile.am: Include lib/freeze.mk to get the dependencies
	on Autotest and M4sh.
	($(TESTSUITE)): Use $(autotest_m4f_dependencies).

	Use dnl, not the KILL diversion.
	Extracted from...
	(AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
	(AC_CONFIG_LINKS): here.
	Adjust.
	Don't use the KILL diversion, as it kills spurious output, which
	results in failures being hidden.
	Use m4_defn where appropriate.

	(AC_C_INLINE): Do not require AC_PROG_CC_STDC.
	(AC_C_CONST): Same.

	* lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
	(AS_SHELL_SANITIZE): Invoke it.
	(AS_BASENAME): AS_REQUIRE it, and use $as_basename.

2002-03-26  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Portable Shell): Add pointers to FAQs.

2002-03-26  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Introduction): The GNATS base moved.

2002-03-25  Paul Eggert  <eggert@twinsun.com>

	* tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
	as POSIX requires, as it doesn't work with Zsh.
	* doc/autoconf.texi (Assignments): Document the problem.

2002-03-25  Alexandre Duret-Lutz  <duret_g@epita.fr>

	* doc/autoconf.texi (Limitations of Make): Mention more issue
	about VPATH, overriding of macros in sub-makes, and handling of
	SHELL.

2002-03-21  Paul Eggert  <eggert@twinsun.com>

	* doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
	problem with here-document buffer boundaries.

	* lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
	when reinvoking the shell, to work around problems with installers
	who put strange things like "cd" commands in their environments.

2002-03-19  Akim Demaille  <akim@epita.fr>

	* tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
	From Aaron Ucko.

2002-03-19  Akim Demaille  <akim@epita.fr>

	* bin/autoscan.in (scan_file): Specify the location in `&used'
	invocations.
	From Nicolas Joly.

2002-03-19  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
	From Nishio Futoshi.

2002-03-19  Akim Demaille  <akim@epita.fr>

	* lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.

2002-03-18  Paul Eggert  <eggert@twinsun.com>

	* doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
	(Limitations of Usual Tools): Add mkdir section.

	* lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
	(AS_MKDIR_P): Require it.  Use mkdir -p if available, falling
	back on AS_DIRNAME to compute prefixes otherwise; this is
	roughly what mkinstalldirs does.  That way, we need not have
	our own filename disassembler.  The old disassembler did not
	work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.

	* lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
	Create at_test_all by a series of assignments,
	not by a single assignment of a long string.  The latter causes ksh
	version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
	presumably because of a buffer overrun.

2002-03-14  Paul Eggert  <eggert@twinsun.com>

	* lib/autotest/general.m4 (at_times_skip):
	Renamed from at_times.  Now a boolean.
	ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
	says 'times: not found'.

2002-03-14  Akim Demaille  <akim@epita.fr>

	* bin/autoreconf.in (&study_gettextize): New.
	(&autoreconf): Handle newest gettextize.
	Rerun aclocal if needed.
	Suggested by Andreas Schwab.

2002-03-13  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Special Shell Variables): More about IFS.

2002-03-13  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Header Portability): New.
	Add information about stdint.h and inttypes.h from Paul Eggert.

2002-03-13  Akim Demaille  <akim@epita.fr>

	* doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
	-p'.
	From Bob Proulx.

2002-03-12  Akim Demaille  <akim@epita.fr>

	* lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
	m4_require.

2002-03-11  Andreas Schwab  <schwab@suse.de>

	* configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
	does not do it if --with-lispdir is given.

	(AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
	configure.ac.
	(_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
	arguments.
