Autoconf 2.57d released

<#secure method=pgpmime mode=sign>

This is our candidate release for Autoconf 2.58.  We plan to release
it soon, so that Automake 1.8 can be released, hence Libtool 1.6, so
that GNU M4 2.0 can be shipped, enabling Autoconf 2.60 ;)

Please, test it thoroughly.

NEWS

* Major changes in Autoconf 2.57d

* Major changes in Autoconf 2.57b

  Released 2003-08-24, by Akim Demaille.

** Autotest and local.at
  The optional file local.at is always included in Autotest test suites.

** Warnings
  The warnings are always issued, including with cached runs.
  This became a significant problem since aclocal and automake can
  run autoconf behind the scene.

** autoheader warnings
  The warnings of autoheader can be turned off, using --warning.
  For instance, -Wno-obsolete disables the complaints about acconfig.h
  and other deprecated constructs.

* Major changes in Autoconf 2.57a

** New macros
  AC_C_RESTRICT, AC_INCLUDES_DEFAULT.

** AC_DECL_SYS_SIGLIST
  Works again.

** AC_FUNC_MKTIME
  Now checks that mktime is the inverse of localtime.

** Improve DJGPP portability
  The Autoconf tools and configure behave better under DJGPP.

** Present But Cannot Be Compiled
  New FAQ section dedicated to the mystic

    configure: WARNING: pi.h: present but cannot be compiled
    configure: WARNING: pi.h: check for missing prerequisite headers?
    configure: WARNING: pi.h: proceeding with the preprocessor's result
      messages.

** Concurrent executions of autom4te
  autom4te now locks its internal files, which enables concurrent
  executions of autom4te, likely to happen if automake, autoconf,
  autoheader etc. are run simultaneously.

** Libtool
  Use of Libtool 1.5 and higher is encouraged.  Compatibility with
  Libtool pre-1.4 is not checked.

** Autotest
  Testsuites no longer rerun failed tests in verbose mode; instead,
  failures are logged while the test is run.

  In addition, expected failures can be marked as such.

**********************************************************************
2003-09-25  Akim Demaille  <[email protected]>

	Version 2.57d.

	* bin/Makefile.am (edit): Handle '@configure_input@'.
	(autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
	(ifnames): chmod -w.
	* tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
	executables, not bin/ executables!  Otherwise all the magic needed
	to find non installed files is turned off.  This caused a failure
	of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
	as found in its environment (sent by tests/autoreconf): pointing
	to bin/autom4te that could not find its files.
	* tests/mktests.sh: Force the replacement of generated files, for
	the sake of "mv" program that are interactive when overwriting a
	-w file.
	* config/install-sh: Upgrade from CVS Automake.

2003-09-23  Paul Eggert  <[email protected]>

	* doc/autoconf.texi (Limitations of Builtins): Document test -h
	versus test -L issues.

	about inconsistency if the preprocessor is set to give errors for

	Add support for newer Fortran dialects.  The F77 interface is
	unchanged, and continues to support Fortran 77.  New FC macros
	correspond to all the old F77 macros, with output variables FC,
	FCFLAGS, and FCLIBS.  AC_PROG_FC defaults to picking the newest
	available dialect, but older dialects can be specified.  There are
	new macros AC_FC_SRCEXT to set the source extension, and
	AC_FC_FREEFORM to accept free-form source files.

	* lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
	New macros.
	(AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
	* lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
	_AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
	_AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),
	AC_LANG_PROGRAM(Fortran), AC_LANG_CALL(Fortran),
	AC_LANG_PREPROC(Fortran), AC_LANG_COMPILER(Fortran),

	_AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
	AC_FC_SRCEXT, AC_FC_FREEFORM):
	New macros.
	(AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
	AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
	AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
	Rewrite in terms of the above.

2003-09-02  Paul Eggert  <[email protected]>

	* doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
	Document problems with timestamp resolution that 'make', 'cp -p', and
	'touch -r' have.

2003-08-27  Akim Demaille  <[email protected]>

	* tests/m4sugar.at (cross_warning): Make sure to enable the
	output, so that we can track spurious m4sugar output.
	* tests/local.at: Require 2.57.
	(AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
	are defaulted by AT_CHECK anyway.
	Use AT_CHECK_AUTOM4TE.
	* lib/m4sugar/m4sugar.m4: There should be no output at all: add a
	missing dnl.

2003-08-27  Akim Demaille  <[email protected]>

	* bin/autoheader.in: Issue the "Using auxiliary..." message only
	when -Wobsolete is set.
