2003-09-02  Steven G. Johnson  <[e-mail]>

	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_DIALECT_YEAR, _AC_F95_FC, _AC_F90_FC, _AC_F77_FC,
	_AC_PROG_FC, AC_PROG_FC, _AC_PROG_FC_G, _AC_PROG_FC_C_O,
	AC_PROG_FC_C_O, _AC_PROG_FC_V_OUTPUT, _AC_PROG_FC_V,

	_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.
	(_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
	* lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

	* 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  <[e-mail]>

	* 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  <[e-mail]>

	* bin/autom4te.in: Adjust to output the call stack.
	* tests/m4sugar.at (m4@&t@_warn): Adjust.

2003-08-22  Akim Demaille  <[e-mail]>

	* lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
	* bin/autom4te.in: Adjust.

	&parse_WARNINGS.
	($help): Use Autom4te::ChannelDefs::usage.
	* bin/autoscan.in: Use Autom4te::ChannelDefs.
	* lib/Autom4te/General.pm: Don't export error: you don't own it.

2003-08-21  Akim Demaille  <[e-mail]>

	First stab at preserving warnings between calls to autom4te,
	including when the cache is used.

	There are still several issues: (i) there are too many runs of m4
	(one for include, one for warnings, and some more), (ii) warnings
	spreading on several lines are not handled gracefully, (iii) the
	code meant to have the call stack display for errors does not work
	(its handling should move from m4 to autom4te).

	* bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
	Use them.
	(@preselect): Add m4_warn.
	($exit_status): Remove, use $exit_code.
	($help): Use Autom4te::ChannelDefs::usage.
	(&handle_m4): No longer define the m4_warnings.
	At each run, extract and report the warnings.
	Always cache the result, including if the exit status is on
	failure, since if nothing changes, we should result in the same
	failure, hence we can use the cache.
	* lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
	(_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
	Remove.
	(m4_warn): Redefine as a do-nothing: it is its invocation that
	matters, as warnings are now reported via traces.
	* lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
	the contents of m4_warn: make it _call_ m4_warn, so that tracing
	the latter reveals calls to the former.

	Adjust the tests.

	* tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

2003-08-21  Akim Demaille  <[e-mail]>

	* bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
	Use them.

2003-08-21  Akim Demaille  <[e-mail]>

	* lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
	forward order.
	* lib/Autom4te/ChannelDefs.pm: Doc typos.
	(&parse_warnings): Accept a list of warning requests.
	(&usage): Return a string, not a side effect.
	(cross): New warning category.

2003-08-21  Akim Demaille  <[e-mail]>

	* lib/Autom4te/Configure_ac.pm (&find_configure_ac)
	(&require_configure_ac): Accept an optional directory argument.
	($configure_ac): Remove.
	* lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
	(&catfile): Remove.
	* bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
	* bin/autoscan.in: Adjust.

2003-08-20  Akim Demaille  <[e-mail]>

	* bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
	Reported by Alexandre Duret-Lutz.

2003-08-20  Akim Demaille  <[e-mail]>

	* bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
	* bin/autom4te: Adjust.
	In particular, be Autoconf tools are really silent when properly
	working, bind the verbosity of the 'note' channel to $verbose.
	* lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
	(&xsystem, &contents): Remove, since they are exported by...
	* lib/Autom4te/FileUtils.pm: this.
	More perldoc.
	* lib/Autom4te/General.pm (&up_to_date_p): Move to...
	* lib/Autom4te/FileUtils.pm: here.

2003-08-20  Akim Demaille  <[e-mail]>

	* lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm

	STDOUT & STDERR arguments.

2003-08-14  Derek Price  <[e-mail]>

	* lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
	DESCRIPTION rather than FILE and LINE.  Shorten result to fit in new,
	shorter column three.  Add DESCRIPTION to log file content.

2003-08-13  Derek Price  <[e-mail]>

	* lib/autotest/general.m4 (AT_INIT): Correct typo in final status
	output.

2003-08-12  Derek Price  <[e-mail]>

	in Bash 2.01.  Problem reported by Brian Gough in
	<http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.

2003-07-25  John W. Eaton  <[e-mail]>

	* lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
	-lcrt1.o, for OS X.  (trivial change)

2003-07-07  Paul Eggert  <[e-mail]>

	* lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
	inside '#ifndef __cplusplus'.  Problem reported by
	Bob Friesenhahn.

2003-07-06  Bill Clarke  <[e-mail]>

	* lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
	'long', not 'int', for benefit of Sun's recent C++ compilers
	(trivial change).  See:
	http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
	(This really should be 'intptr_t', not 'long', but that would
	take more work.)

2003-06-25  Akim Demaille  <[e-mail]>

	* lib/Makefile.am (autom4te.cfg): Make it read only.
	Depend on Makefile since it contains substitutions.
	From Paolo Bonzini.
	* lib/autom4te.in (args): Add local.at? for Autotest args.
	This change was made on autom4te.cfg which is generated.
	Reported by Raja R. Harinath.

2003-06-25  Akim Demaille  <[e-mail]>

	* doc/autoconf.texi (Header Portability): sys/mount.h.
	From Gareth McCaughan.

2003-06-23  Akim Demaille  <[e-mail]>

	* lib/autotest/general.m4 (AT_INIT): Report a single config.log,
	not all of them.  This fixes 1. the fact that when testing
	Autoconf there are many many config.log, 2. the incorrect use of
	top_srcdir to find config.log.
	Don't mix the detailed output of failed test with the summary of
	failures.  Rather, append detailed log afterwards.

2003-06-23  Akim Demaille  <[e-mail]>

	* tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
	always run: output config.log on $at_group_log.

2003-06-23  Akim Demaille  <[e-mail]>

	* tests/torture.at (#define header templates): Don't use quotes in
	C++ comments as it puzzles Emacs' sh font-lock-mode.

2003-06-23  Akim Demaille  <[e-mail]>

	* tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
	* lib/autom4te.cfg (args): Add local.at? for Autotest args.
