changelog.2

autoconf 2.59版,可用于redhat系统.用于编译原码,编写makefile文件.

	* m4sugar.m4 (m4_defn, m4_undefine, m4_popdef): Unlike the
	builtin, fail on undefined symbols.
	* tests/torture.at (Torturing config.status): Stop playing nasty
	tricks with changequote.
	(AC_DEFUBST): Move here from...
	* tests/aclocal.m4: there.

2001-01-18  Akim Demaille  <[e-mail]>

	Various cleanups and consistency checks.

	* m4sugar.m4: Formatting changes.
	* acgeneral.m4 (AC_DIVERT_PUSH, AC_DIVERT_POP, AC_REQUIRE)
	(AC_DIAGNOSE, AC_FATAL, AC_MSG_WARN, AC_MSG_NOTICE, AC_MSG_ERROR):
	Use m4_copy to define them, in order to keep a good $0.
	(AC_INIT): AC_LANG_PUSH C, not AC_LANG, to initialize the stack.
	* aclang.m4 (AC_LANG_PUSH): Dont't use m4_defn on undefined macros.
	(AC_LANG_POP): Admit an argument specifying the language we quit
	when popping.
	Adjust Autoconf's AC_LANG_POPs.
	* tests/tools.at (AWK portability): Don't depend on AC_INIT.
	(autoconf --trace: user macros): Obviously I
	meant TRACE1, not AC_TRACE1.

2001-01-17  Akim Demaille  <[e-mail]>

	* m4sugar.m4 (m4_undefine, m4_popdef): Don't tolerate undefined
	arguments.
	(_m4_expansion_stack): Rename as...
	(m4_expansion_stack): this, and change its value: instead of using
	the pushdef stack to stack each *line* of the stack, each
	definition contains the whole stack.  I.e., to display the whole
	stack, instead of popdefing and displaying each definition, just
	display the current definition.
	(m4_expansion_stack_push, m4_expansion_stack_pop): New.
	* tests/atspecific.m4 (AT_CHECK_AUTOCONF): Let $2 be the expected
	exit status.

2001-01-16  Akim Demaille  <[e-mail]>

2001-01-16  Akim Demaille  <[e-mail]>

	When default headers are used, check for their presence.
	Suggested by Jim.

	* acgeneral.m4 (_AC_INIT_DEFAULTS): Don't define
	ac_includes_default, since...
	(_AC_INCLUDES_DEFAULT_REQUIREMENTS): this new macro does.
	(AC_INCLUDES_DEFAULT): Require the former when default includes
	are used.
	(AC_CHECK_MEMBERS, _AC_CHECK_TYPE_NEW): Don't require

	* tests/atgeneral.m4 (AT_INIT): When the suite failed, complain
	before creating the debug scripts.
	Create a log file.
	When ignoring a test, display a reassuring `ok' for stressed
	users, and say `skipped' instead.
	Simply run `testsuite' with the failed tests instead of running
	the debug scripts, this avoids having zillions of banners `Testing
	Blabla 2.13' (another means to avoid these banners is to have the
	test suite succeed :-).

2001-01-15  Akim Demaille  <[e-mail]>

	* sh.m4 (AS_BOX, _AS_BOX_LITERAL, _AS_BOX_INDIR): New.
	* tests/atgeneral.m4: Use it.

	(AC_PROG_CC, AC_PROG_CXX): Use it.
	(AC_PROG_CC_STDC): Be sure to remove tmp files.

	(AC_HAVE_FUNCS): Test AC_HAVE_FUNCS!

	look for, after the other Fortran 90 compilers.

2001-01-11  Akim Demaille  <[e-mail]>

	* aclang.m4: Use m4_copy to duplicate macros.

2000-12-20  Akim Demaille  <[e-mail]>

	* tests/atgeneral.m4 (AT_CLEANUP_FILE_IFELSE): Fix the regexp: the
	pattern ` state* ' was added many times for `*' was improperly

2000-12-19  Akim Demaille  <[e-mail]>

	* tests/compile.at (AC_PROG_CPP without warnings, GNU Fortran 77):
