2001-05-19  Akim Demaille  <[e-mail]>

	Adjust to admit
	(AC_PROG_CPP, AC_PROG_CXXCPP): Use it.
	Reported by Daniel Carroll.

2001-04-26  Pavel Roskin  <[e-mail]>

	* acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS): Use two backslashes

2001-04-22  Jim Meyering  <[e-mail]>

2001-04-20  Tim Van Holder  <[e-mail]>

	* acgeneral.m4 (AC_OUTPUT): Close the descriptor before running
	config.status so config.log is properly created on MS-DOS.

2001-04-20  Nicolas Joly  <[e-mail]>

	or broken autoupdate.

	* doc/autoconf.texi: Replace documentation for obsolete
	AC_LIBOBJ_DECL with clearer documentation for AC_LIBSOURCE
	and AC_LIBSOURCES, improving the AC_LIBOBJ docs as well.

2001-04-17  Steven G. Johnson  <[e-mail]>

	* doc/autoconf.texi: Fixes for punctuation and grammar..  Replace
	"..." with "@dots{}" except when "..." is in literal code.

2001-04-17  Nicolas Joly  <[e-mail]>

	* acgeneral.m4 (_AC_LINK_IFELSE): Be sure to remove temporary

	felicity, and grammar.

2001-04-11  Steven G. Johnson  <[e-mail]>

	* doc/autoconf.texi (AC_F77_WRAPPERS): Mention C++ as well as C.
	In the example, don't #ifdef F77_FUNC before using it, as that
	would push any errors to link-time rather than compile-time; note
	that the user can test this to invoke alternative behavior.

2001-04-11  Akim Demaille  <[e-mail]>

	* autoconf.sh (Task script): Be sure that `forbidden.rx' and
	`allowed.rx' exist when AWK loads then.
	Reported by Rainer Orth.

2001-04-11  Steven G. Johnson  <[e-mail]>

	* doc/autoconf.texi: A few more minor modifications for clarity,
	grammar, and formatting.

2001-04-10  Lars J. Aas  <[e-mail]>

	* Makefile.am: AC_SUBST fixes for PACKAGE_NAME, VERSION, PACKAGE...
	* configure.in: Moved here.
	Suggested by Akim Demaille and Raja R Harinath.

2001-04-10  Lars J. Aas  <[e-mail]>

	* acgeneral.m4 (_AC_OUTPUT_CONFIG_STATUS):  Re-enable logging to
	`config.log' from `config.status', but delay logging till after
	command line option processing.

2001-04-10  Lars J. Aas  <[e-mail]>

	* autoupdate.in (print_usage): print "\ at end of line does not
	work as expected, so change block to here-doc instead.
	(print_version): Same.

2001-04-09  Steven G. Johnson  <[e-mail]>

	* doc/autoconf.texi: Replace all tab characters with (8) spaces,
	lest the formatting of example code, etcetera, be messed up.

2001-04-09  Steven G. Johnson  <[e-mail]>

	* doc/autoconf.texi: Rephrase various parts for clarity, felicity,
	and/or grammar.

2001-04-09  Steven G. Johnson  <[e-mail]>

	* doc/autoconf.texi: Clean up cache documentation: Document
	--config-cache/-C option, and recommend instead of --cache-file.
	Indent example AC_CACHE_VAL macros for clarity.  Add new
	"Cache Checkpointing" section for AC_CACHE_SAVE (and
	AC_CACHE_LOAD), so that the "Cache Files" section focuses solely
	on features visible to end-users (e.g. to better fit the cross
	references).  Various minor rewordings for clarity, felicity,
	and/or grammar.

2001-04-09  Steven G. Johnson  <[e-mail]>

	* doc/autoconf.texi: Revert to "configure.in" in the history, since
	"configure.ac" wasn't used in the past, and in any case it is
	probably a good idea to preserve this section verbatim.

2001-04-09  Steven G. Johnson  <[e-mail]>

	* AUTHORS: Fix grammar.

2001-04-09  Lars J. Aas  <[e-mail]>

	needed by dist rules.  Added explanatory comment.
	Problem reported and comment suggested by Raja R Harinath.

2001-04-06  Lars J. Aas  <[e-mail]>

	* Makefile.am: Manual addition of @VERSION@ substitution variable
	as a temporary Automake fix.  Reported by Raja R Harinath.

2001-04-04  Lars J. Aas  <[e-mail]>

	* acgeneral (_AC_INIT_CONFIG_LOG): New macro for setting up the
	config.log file.
	(_AC_INIT_DEFAULTS_FDS): Log to /dev/null instead of config.log.

	* acgeneral.m4 (_AC_INIT_DEFAULTS): Produce better version
	information for config.log header.
	(_AC_INIT_VERSION): Produce better version information for
	`configure --version'.

	* m4sh.m4 (AS_BASENAME): New.
	(AS_SHELL_SANITIZE): Set `$as_me'.

	* tests/atgeneral.m4: Likewise.
	(AT_INIT): Use $PATH_SEPARATOR for walking the path.
	* autoconf.sh: Be DOS-friendly when setting as_me and M4.
	Add quotes to support spaces in $tmp.
	Work around problem in DJGPP port of awk by using a temporary file.

	the first argument of AC_CONFIG_HEADERS.

2001-03-13  Akim Demaille  <[e-mail]>

	* autoscan.pl, autoupdate.in: Use `use' instead of `require' to
