2006-04-23  Paul Eggert  <[e-mail]>

	* doc/autoconf.texi (Runtime): Renamed from "Run Time".  All uses
	of "run time" and "run-time" changed to "runtime", for consistency.
	* lib/autoconf/fortran.m4: Likewise (in comment).
	* lib/autoconf/functions.m4: Likewise.
	* lib/autoconf/general.m4: Likewise.
	* lib/autoconf/headers.m4: Likewise.

	* doc/autoconf.texi (Run Time): Document the exit status situation
	with more accuracy and detail.

2006-04-23  Ralf Wildenhues  <[e-mail]>

	* doc/autoconf.texi (Introduction): The GNU Autoconf Macro
	Archive is not officially `GNU' any more.  Update URL.
	(Defining Directories): Likewise
	* lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.

2006-04-19  Ralf Wildenhues  <[e-mail]>

	* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
	newline from the `trap' code to finish `config.log'; the NetBSD
	/bin/sh resets the exit status after an empty command, as
	documented in doc/autoconf.texi.
	Reported by Dalibor Topic <[e-mail]>.

2006-04-19  Paul Eggert  <[e-mail]>

	* doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
	Suggested by Bruno Haible.

2006-04-18  Paul Eggert  <[e-mail]>

	* configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
	some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
	Instead, just list the shells that we know work.
	* tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg.  All uses
	changed.  Be more cautious about the _cv_ variable.
	* tests/tools.at (Syntax of the shell scripts): Check the
	_cv_ variable once, at first, to avoid an internal autoconf error
	when sh -n does not work.

2006-04-17  Ralf Wildenhues  <[e-mail]>

	* lib/Autom4te/FileUtils.pm: Sync from Automake.

2006-04-16  Paul Eggert  <[e-mail]>

	* lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
	use ">&-" since we're only 99.999% sure that this is portable,
	and since the MinGW bug is fixed in a different way.
	* lib/autotest/general.m4 (AT_INIT): Likewise.

2006-04-16  Stepan Kasal  <[e-mail]>

	* lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
	before opening config.log, to avoid hitting a bug on MinGW.

2006-04-14  Paul Eggert  <[e-mail]>

	* lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
	AS_MESSAGE_LOG_FD before reopening it onto the log file.
	This works around a MinGW bug reported by Eric Paire.
	Make sure that all writes to the log file append to it,
	rather than possibly losing data.
	* lib/autotest/general.m4 (AT_INIT): Likewise.

2006-04-14  Stepan Kasal  <[e-mail]>

	* lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
	description.

2006-04-13  Ralf Wildenhues  <[e-mail]>

	* NEWS: Update.

	* configure.ac (AC_INIT): Bump to 2.59d.

2006-04-12  Ralf Wildenhues  <[e-mail]>

	Version 2.59c.

	* Makefile.maint (news-date-check): Do not require a leading `*'
	before the release date in NEWS.

2006-04-12  Stepan Kasal  <[e-mail]>
	and Ralf Wildenhues  <[e-mail]>

	* lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
	the instantiated file do not contain the string 'datarootdir'
	but contain @datadir@, @docdir@, @infodir@, @localedir@, or
	@mandir@, replace the reference '${datarootdir}' by the value.
	* tests/torture.at (datarootdir workaround): New test.
	* NEWS: Advertise this temporary fixup.
	Based on a patch by Bruno Haible, reported and analyzed by
	Paul Eggert and Noah Misch.

2006-04-12  Eric Blake  <[e-mail]>

	* tests/autotest.at (Debugging a failed test): Fix comment.

2006-04-12  Stepan Kasal  <[e-mail]>

	* lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
	all the changes since 2006-04-07.

2006-04-11  Ralf Wildenhues  <[e-mail]>

	* lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
	succeeded, but `ln -s file dir' failed, take care to remove the
	leftover target before the next test, to prevent its spurious
	failure; also make sure `ln file dir' works before selecting it.
	Thanks to Keith Marshall for pointing this out.
	* THANKS: Update.

	* lib/autotest/general.m4 (AT_INIT): Store quoted variable
	assignments in `at_debug_args', so that we put them correctly
	in the `run' script.
	* tests/autotest.at (Debugging a failed test): Unmark XFAIL.
	Reported by Eric Blake.

2006-04-11  Eric Blake  <[e-mail]>

	* tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
	top-level tests after micro-suite has been run.   Used in...
	(Debugging a successful test, Debugging script and environment),
	(Debugging a failed test): ...these new tests.  The first of these
	is fixed by...
	* lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
	macro, split out from...
	(AT_INIT): ...here, so that using -d also generates a run script.
	Document that -d inhibits top-level logging.
	* doc/autoconf.texi (testsuite Invocation): Document that -d only
	inhibits top-level logging; debug scripts are created.

	* lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
	check.
	* tests/autotest.at (Empty test, Empty check): New test to check it.

	* lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
	from gcc.

2006-04-10  Stepan Kasal  <[e-mail]>

	* tests/mktests.sh: Use "trap '' 0", not "trap 0".  Do not touch
	the files if a problem appears.  Make the empty *.at files
	read-only, too.  Proposed by Ralf Wildenhues.

2006-04-10  Ralf Wildenhues  <[e-mail]>

	* config/Makefile.am: Add comment to force updated Makefile.in.

	* lib/freeze.mk: Fix typo in comment.  Unlike the last, white
	space only patch to this file, this patch causes the Makefile.in
	files that include freeze.mk to be updated, and thus have a
	newer time stamp again, which in turn makes a pristine CVS
	checkout have correct time stamps.

	* Makefile.maint (cvs-sv): New macro, to be used..
	(config.guess-url_prefix, config.sub-url_prefix)
	(texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
	point to CVS text checkout of Gnulib files.
	(copyright-check): Bump current year.
	(announcement): Do not hard-wire `./announce-gen'.
	(cvs-update): Propagate failures of `cvs' and `move-if-change'
	correctly.
	* Makefile.cfg (executable-update): Use `chmod a+x' instead of
	`chmod +x'.
	(wget_files): Update config.guess, config.sub, texinfo.tex by
	`wget-update', now that their URLs work again.

2006-04-10  Paul Eggert  <[e-mail]>

	* doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
	Problem noted by Paul D. Smith.

2006-04-10  Ralf Wildenhues  <[e-mail]>

	* doc/autoconf.texi: Remove unused words from word list.
	* .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
	.x-sc_trailing_space: New files.

	* doc/standards.texi: Sync from gnulib.

	* NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
	`LIBOBJDIR' as experimental.

	* lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
	with a target directory; it's internally implemented as `cp'
	anyway, but since Autoconf advertises the possibility to use
	a target directory when LN_S is `ln -s', we need to find out.
	Reported by Rolf Ebert <[e-mail]> against MSYS,
	analyzed by Keith Marshall <[e-mail]>.

	* THANKS: Update.

2006-04-10  Paul Eggert  <[e-mail]>

	* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
	confdefs.h as-is.  In general, if it has backslash-newline or the
	like, then it doesn't work either to sort or to remove empty
	lines.

2006-04-09  Stepan Kasal  <[e-mail]>

	* tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.

2006-04-09  Alexandre Duret-Lutz  <[e-mail]>

	* lib/autom4te.in (Automake-preselections): Preselect
	_AM_SUBST_NOTMAKE.

2006-04-08  Paul Eggert  <[e-mail]>

	* lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
	apostrophe within a single-quoted string, as this is the usual
	tradition and is easier to read than '"'"'.  Don't rely on the
	shell treating "$/" like '$/'.  Use a more-consistent indenting
	style for the trap.

2006-04-09  Eric Blake  <[e-mail]>

	* tests/autotest.at (Backquote command substitution),
	(Multiline backquote command substitution): Remove mistaken
	AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
	applied...
	(Parenthetical command substitution, Multiline parenthetical
	command substitution): here.

2006-04-08  Paul Eggert  <[e-mail]>
