changelog

这是一个自动生成MAKEFILE的工具。在LINUX工程项目里是很好的帮手。希望对大家有点帮助。

	* Version 2.9 released.
	* acgeneral.m4 (AC_ACVERSION): Updated to 2.9.

Wed Mar 13 12:49:51 1996  Roland McGrath  <[e-mail]>

	* acgeneral.m4 (AC_OUTPUT_HEADER): Undo last change to $ac_dB,
	and instead change the code written into conftest.hdr.

Tue Mar 12 02:51:24 1996  Roland McGrath  <[e-mail]>

	* acgeneral.m4 (AC_OUTPUT_HEADER): Apply Jan 15 fix to
 	AC_OUTPUT_MAKE_DEFS here too: Match `#define foo' without trailing
 	space in confdefs.h.  Before configure would lose if all its trailing
 	whitespace got stripped, and that can happen in mail.

Sun Mar 10 20:30:09 1996  Roland McGrath  <[e-mail]>

	* acgeneral.m4 (AC_INIT_NOTICE): Add 95 and 96 to copyright years.

Sat Mar  9 18:28:42 1996  Roland McGrath  <[e-mail]>

	* acgeneral.m4 (AC_CHECK_LIB): Add missing [.

Fri Mar  8 15:06:48 1996  Roland McGrath  <[e-mail]>

	* acgeneral.m4 (AC_CHECK_LIB): Declare $2 to override gcc2 internal
	prototype.

	* Version 2.8 released.

Wed Mar  6 14:38:31 1996  Roland McGrath  <[e-mail]>

	* acgeneral.m4 (AC_CHECK_LIB): Use a cache variable name containing
	both the library and function name.

Tue Jan 16 16:39:21 1996  Roland McGrath  <[e-mail]>

	* acgeneral.m4 (AC_CHECK_PROG): Take optional 6th arg, full name
	of program to reject if found in search path.
	* acspecific.m4 (AC_PROG_CC): If gcc not found use AC_CHECK_PROG
	for cc, rejecting /usr/ucb/cc.
	Fatal configure error if no $CC found at all.

Mon Jan 15 15:57:36 1996  Roland McGrath  <[e-mail]>

	* acgeneral.m4 (AC_OUTPUT_MAKE_DEFS): Match `#define foo' without
	trailing space in confdefs.h.  Before configure would lose if
	all its trailing whitespace got stripped, and that can happen in mail.

Fri Jan 12 14:38:37 1996  Roland McGrath  <[e-mail]>

	* acgeneral.m4 (AC_TRY_CPP): Use "" instead of '' when setting
	ac_try; we need one level of expansion there for $ac_cpp, then
	AC_TRY_EVAL does one more for its the expansion of $ac_cpp.

Thu Jan 11 10:38:19 1996  Roland McGrath  <[e-mail]>

	* acgeneral.m4 (AC_LANG_C, AC_LANG_CPLUSPLUS): Removed echo cmds
	from $ac_cpp, $ac_compile, and $ac_link.
	(AC_TRY_EVAL, AC_TRY_COMMAND): New macros for running tests' commands.
	Always put the configure source line and command line into config.log.

	* acspecific.m4: Use AC_TRY_EVAL and AC_TRY_COMMAND for running
	all tests.

Fri Jan  5 17:50:28 1996  Roland McGrath  <[e-mail]>

	* acspecific.m4 (AC_PATH_X, AC_PATH_X_XMKMF, AC_PATH_X_DIRECT):
	Rearrange logic: do no tests if $with_x=no; make incl and lib
	tests independent, and distinguish unset from empty.

	* autoconf.sh (undefined macro check): \ sed \s inside "".  If
	grep $name in $infile misses, give error message that there must
	be an Autoconf bug.

Tue Dec 19 10:49:20 1995  David J. MacKenzie  <[e-mail]>

	* autoconf.sh: Ignore undefined macros in shell comments.

Mon Dec 11 22:12:54 1995  Roland McGrath  <[e-mail]>

	ANSI.  From [e-mail] (Doug Evans).
	(AC_TYPE_SIGNAL) [__cplusplus]: Give a full prototype.
	From [e-mail] (Chad Hurwitz).
	(AC_FUNC_VFORK): If cross-compiling, use AC_CHECK_FUNC instead.
	From steve chamberlain <[e-mail]>.

Tue Sep  5 20:37:48 1995  Paul Eggert  <[e-mail]>

	CC 3.0 requires this.

Tue Aug  8 20:10:12 1995  Paul Eggert  <[e-mail]>

	  From Karl Berry.

	* acgeneral.m4 autoheader.sh: Change tr [a-z] [A-Z] into expansion

Sat May  6 17:29:07 1995  David J. MacKenzie  <[e-mail]>

	* acspecific.m4 (AC_PROG_CPP): If CPP is already set, use that as

	* Version 2.3.

	* acgeneral.m4 (AC_OUTPUT): Add quotes around the echo arguments
	in the trap, so backslashes aren't required for multiline input.

	(AC_HEADER_STAT): Check whether S_IFDIR is defined, to work around
	ISC bug reported by [e-mail] (Rick Coupland).

	* autoheader.sh: Better solution to @BOTTOM@ printing.
	From Paul Eggert.

Mon Feb 13 18:13:11 1995  Roland McGrath  <[e-mail]>

	* acspecific.m4 (AC_PROG_CC_C_O): Use sed filter to make sure
