changelog.1

LINUX下的源码工具,可自己分析,或者直接装在系统上作为应用

	Add another example of dependencies.

	* acspecific.m4 (AC_PROG_CXX, AC_PROG_CXXCPP, AC_REQUIRE_CPP): New
	macros based on work by [e-mail] (david d zuhn).
	(AC_DECLARE_YYTEXT): Use AC_REQUIRE_CPP.  Warn that it's broken.
	(AC_STDC_HEADERS): Use AC_REQUIRE_CPP.
	(AC_MMAP): New macro from Mike Haertel and Jim Avera.

	* acgeneral.m4 (AC_PARSEARGS): Check for missing arguments to
	options.  Recognize --target.  Save the original args before
	modifying them.
	(AC_INIT): Call AC_LANG_C.
	(AC_PREPARE): Don't save the original args here (too late).
	(AC_LANG_C, AC_LANG_CPLUSPLUS, AC_LANG_SAVE, AC_LANG_RESTORE):
	New macros based on work by [e-mail] (david d zuhn).
	(AC_HEADER_EGREP, AC_PROGRAM_EGREP, AC_COMPILE_CHECK,
	AC_TEST_PROGRAM, AC_TEST_CPP): Use AC_REQUIRE_CPP and ac_ext and
	ac_cpp.

	* autoheader.sh: Update the file even if it is unchanged, to avoid
	foiling a Makefile rule that makes it from configure.in.  If you
	let the rule for making config.status from configure create
	config.h from config.h.in, then an unnecessary update here will
	not cause unneeded recompilation.  Recompilation should only
	happen if config.h is updated, which won't occur if config.h.in
	had the same contents, even if its timestamp changed.  (Ick.)

	* Makefile.in (Makefile): Don't depend on config.status, to avoid
	running config.status too many times.

Fri Mar 18 00:43:21 1994  David J. MacKenzie  ([e-mail])

	* autoconf.texi: Document AC_FIND_XTRA.

	* acgeneral.m4 (AC_OUTPUT): Remove VPATH lines if srcdir=., to
	work around Sun make bug.  From Karl Berry.

	Rename internal use shell variables to start with "ac_".

	Trap signal 2 (SIGINT), not signal 3 (SIGQUIT), which means stop
	without cleaning up.  From [e-mail] (Paul Eggert).

	* acspecific.m4 (AC_FIND_XTRA): New macro from Karl Berry
	([e-mail]).
	(AC_FIND_X, AC_ISC_POSIX): Provide self.

	(AC_DECLARE_YYTEXT): Move AC_SUBST.  Don't quote value of
	DECLARE_YYTEXT.  From Karl Berry.

	(AC_PROG_CPP): Include $CFLAGS in CPP.

	Rename internal use shell variables to start with "ac_".

	* autoconf.sh, autoheader.sh: Trap signal 2 (SIGINT), not signal 3
	(SIGQUIT), which means stop without cleaning up.  From
	[e-mail] (Paul Eggert).

	* autoconf.texi: Mention shell variable prefixes.

	* autoconf.texi: Work around RCS substitution in AC_REVISION
	example.

Wed Mar 16 19:55:17 1994  Noah Friedman  ([e-mail])

	"../" as the number of subdirectories deep the file being created is.

	-lutil check.

Fri Feb  4 17:17:11 1994  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_OUTPUT_HEADER): Move creation of conftest.sed
	outside of `for' loop.  We need only do this once for all the
	output files.

Fri Jan 21 16:35:00 1994  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_PROG_INSTALL_INSTALL_SH): New macro for

	expansion.

	* acgeneral.m4 (AC_PROGRAM_PATH, AC_PROGRAMS_PATH): New macros.
	* autoconf.texi (General Tests): Document them.

	* configure.in: Use AC_PROGRAMS_PATH to find m4, not AC_PROGRAMS_CHECK.
	Put `m4' in the list of progs-to-check, since we want the absolute
	pathname for that too if we can get it.

Fri Dec 17 13:44:24 1993  Noah Friedman  ([e-mail])

	* acspecific.m4 (AC_ALLOCA): define HAVE_ALLOCA if alloca is

	in more places.

Sun Nov 28 21:57:31 1993  Noah Friedman  ([e-mail])

	* acgeneral.m4 (AC_NOTICE): Replace "this program" with "this
	configure script" to disambiguate between configure and the
	program it is distributed with (which can have different terms).

Tue Nov 23 19:41:53 1993  Noah Friedman  ([e-mail])

	* acspecific.m4 (AC_FIND_X_DIRECT): Use the shell variable
	`x_direct_test_include' to choose the include file to search for.

Sat Nov 20 17:58:09 1993  Noah Friedman  ([e-mail])

	* acspecific.m4 (AC_FIND_X_DIRECT): Search for R6 includes & libs
	in various places.  Look for /usr/athena/include & /usr/athena/lib.
	Make AC_HAVE_LIBRARY check for the library specified by the shell
	variable `x_direct_test_library', rather than hardcoding Xt (to
	which the shell variable now defaults).

Thu Nov 18 18:17:21 1993  David J. MacKenzie  ([e-mail])

	* acgeneral.m4 (AC_OUTPUT_HEADER): Use ! instead of @ as the
	sed substitution separator.

	* acspecific.m4 (AC_UNISTD_H, AC_USG, AC_MEMORY_H): Call it.

	* acspecific.m4 (AC_LONG_FILE_NAMES): Try to create files in
