autoconf是一个产生可以自动配置源代码包

2001-01-26  Tim Van Holder  <[e-mail]>

	* tests/Makefile.am (testsuite): Use testsuite.tmp, not
	testsuite-tmp as temporary file.

2001-01-25  Assar Westerlund  <[e-mail]>

	* autoreconf.sh: Also find configure.in.

2001-01-24  Akim Demaille  <[e-mail]>

	* configure.in: Bump to 2.49d.

2001-01-24  Akim Demaille  <[e-mail]>

	Version 2.49c.

2001-01-24  Jim Meyering  <[e-mail]>

	* autoscan.pl (output): Detect/report a close failure.

2001-01-24  Akim Demaille  <[e-mail]>

	Preserve INSTALL too.

	* acgeneral.m4 (_AC_OUTPUT_FILES): Use ac_INSTALL for internal
	computations, and therefore use INSTALL where ac_given_INSTALL
	was used.
	(_AC_OUTPUT_SUBDIRS): There is no point in computing INSTALL in
	here.  It's not even used.

2001-01-24  Akim Demaille  <[e-mail]>

	While preserved in configure, srcdir is trashed in config.status.
	Reported by Ralf Corsepius.

	* tests/aclocal.m4 (AC_STATE_SAVE): It is ok to modify
	CONFIG_STATUS, DEFS, prefix and exec_prefix.
	It is OK to produce config.* files.
	* tests/atspecific.m4 (AT_CONFIGURE_AC): Save the env *after*
	AC_OUTPUT to check that it doesn't break anything by itself.
	* tests/torture.m4 (srcdir): New test, from Ralf Corsepius.
	* acgeneral.m4 (_AC_OUTPUT_FILES): Use ac_top_srcdir and ac_srcdir
	to preserve srcdir and top_srcdir.
	Remove any use of `ac_given_srcdir' as `$srcdir' being preserved
	is usable.

2001-01-24  Alexandre Duret-Lutz  <[e-mail]>

	configure -q did not work since 2000-11-03.

	* acgeneral.m4 (_AC_INIT_DEFAULTS_FDS): Don't check for $silent,
	tie AS_MESSAGE_FD to stdout unconditionally.
	(_AC_INIT_PARSE_ARGS): If $silent redirect AS_MESSAGE_FD to
	/dev/null.
	* tests/base.at (AC_CACHE_CHECK): New test.

2001-01-24  Tim Van Holder  <[e-mail]>

	* m4sh.m4 (AS_EXECUTABLE_P, _AS_TEST_PREPARE): New macros.
	(AS_SANITIZE_SHELL): Call _AS_TEST_PREPARE.
	* acgeneral.m4 (AC_CHECK_PROG, AC_PATH_PROG): Use AS_EXECUTABLE_P
	instead of test -f.

2001-01-24  Akim Demaille  <[e-mail]>

	* autoscan.pl (generic_macro): s/AC_CHECK_FUNCTIONS/AC_CHECK_FUNCS/.
	* acfunctions: Just like the previous patch.

2001-01-24  Akim Demaille  <[e-mail]>

	* autoscan.pl (@kinds, %generic_macro): New.
	(&init_tables): Use them.
	* acheaders: Run `autoconf -t AC_CHECK_HEADERS:'$1'' on the fileutils,
	and include all these headers in here.
	Don't specify `AC_CHECK_HEADERS' as it's the default.

2001-01-24  Akim Demaille  <[e-mail]>

	* autoscan.pl: Just like the previous patch, but for
	AC_CHECK_FUNCS, AC_CHECK_TYPES, and AC_CHECK_MEMBERS.

2001-01-24  Akim Demaille  <[e-mail]>

	* autoscan.pl (print_unique): Push all the macro invocation
	locations.
	(output_headers): For headers that need to be checked, push either
	the specialized macro, or the generic macro call.
	(check_configure_ac): Handle AC_CHECK_HEADERS.

2001-01-24  Raja R Harinath  <[e-mail]>

	Some non-srcdir build fixes.
	* configure.in (BUGS): Look for file in $srcdir.
	* tests/Makefile.am (MACRO_FILES): Use '..', not '$(top_srcdir)'.

2001-01-24  Akim Demaille  <[e-mail]>

	Don't AC_SUBST too much, as it makes Automake include those
	variables in Makefiles, and drives autoscan to require unneeded
	programs.

	* acgeneral.m4 (_AC_INIT_PREPARE): Don't AC_SUBST CFLAGS,
	CPPFLAGS, CXXFLAGS and LDFLAGS.
	(AC_ARG_VAR): AC_SUBST the var.

	* tests/base.at (AC_REQUIRE & AC_LANG): New test, currently failing.

2001-01-23  Akim Demaille  <[e-mail]>

	* autoscan.pl: Don't use `defined' to check whether an array is
	defined.
	Don't use parens with `defined'.

2001-01-23  Akim Demaille  <[e-mail]>

	* acgeneral.m4 (_AC_INIT_PREPARE): Be sure to quote hashes to
	avoid M4 thinking it's comments.

2001-01-23  Tim Van Holder  <[e-mail]>

	* aclang.m4 (_AC_COMPILER_EXEEXT_O): Use
	AS_IF([AC_TRY_EVAL(ac_link)]) instead of AC_LINK_IFELSE to
	avoid depending on ac_exeext before it's found.
	(AC_PROG_CC, AC_PROG_CXX, AC_PROG_F77): Check for the
	executable extension BEFORE checking whether the compiler
	works, as that test depends on a correct ac_exeext.

	* acgeneral.m4 (_AC_INIT_PREPARE) <trap>: Typo.

2001-01-22  Pavel Roskin  <[e-mail]>

2001-01-22  Tim Van Holder  <[e-mail]>

	* acspecific.m4 (AC_PROG_LN_S): Detect DJGPP < 2.04, which only
	supports 'ln -s' for executables.
