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

	* acgeneral.m4 (AC_OUTPUT): Use variables gen_files and
	gen_config in the loop that generates the output (Make)files,
	instead of hardwiring the filenames.

Sat May 15 17:23:19 1993  Roland McGrath  ([e-mail])

	* autoconf.sh: Accept `-' to mean read stdin as input.
	* autoheader.sh: Likewise.

Fri May 14 12:41:02 1993  Noah Friedman  ([e-mail])

	* autoheader.sh, acspecific.m4 (AC_PREPARE): If `LANG' environment
	variable is set, reset its value to `C'.  This is so `tr [...]'
	works more portably.

Thu May 13 22:56:20 1993  Paul Eggert  ([e-mail])

	* acspecific.m4 (VOID_CLOSEDIR): Test closedir instead of assuming
	that it works.  E.g. dynix closedir yields garbage, but has no
	prototype.  Presumably Xenix closedir had the same problem, so
	stop special-casing it.

Wed May 12 20:25:36 1993  Jim Meyering  ([e-mail])

	* acconfig.h: Add HAVE_LONG_DOUBLE.

Wed May 12 15:07:36 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_DEFINE_UNQUOTED): New macro.

	* acgeneral.m4 (AC_FUNC_CHECK): Include ctype.h instead of stdio.h.
	We want it only to define __stub_* in glibc.  Using stdio.h lost
	when it contained a conflicting prototype for $1; ctype.h has fewer
	prototypes.

	* acconfig.h: Add GETGROUPS_T.

	* acspecific.m4 (AC_PROG_RANLIB): Use : instead of @: for no-op.
	Some braindead make does bizarre magical things with @ in variables.

Mon May 10 14:24:27 1993  Noah Friedman  ([e-mail])

	* acspecific.m4 (AC_HAVE_POUNDBANG): New feature.

	* acgeneral.m4 (AC_OUTPUT): Add more backslashes to character class
	in DEFS filter (sigh).

Sun May  9 14:04:31 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_DEFINE_QUOTE): No AC_QUOTE_SED (was innermost).
	(AC_HEADER_EGREP, AC_PROGRAM_EGREP, AC_TEST_CPP): Put a \ before
	$DEFS in string to be evalled.
	(AC_OUTPUT): Run DEFS through a sed filter that quotes things in it
	from sed (woo woo!) before writing it into config.status.

	* acspecific.m4 (AC_ALLOCA): Use AC_PROGRAM_EGREP to test for [CRAY
	&& !CRAY2], instead of AC_TEST_PROGRAM.  No need to run a program
	for this.

	* acgeneral.m4 (AC_PROGRAM_CHECK): Extract the first word of $2
	when looking for it in PATH, so it can be a program name with args.
	Omit default assignment if $4 is empty.
	Only write verbose msg if $1 was set nonempty.
	* acspecific.m4 (AC_PROG_YACC): Pass 'bison -y' (quoted like that)
	in list to AC_PROGRAMS_CHECK.  Don't test for bison later to add -y
	flag.

Sat May  8 00:23:58 1993  Jim Meyering  ([e-mail])

	* acgeneral.m4 (AC_REPLACE_FUNCS): Add a trailing newline in
	code for AC_COMPILE_CHECK.  Otherwise it got spurious failures.

	* acspecific.m4 (TIME_WITH_SYS_TIME): New macro.

	* Makefile.in (dist): Depend on Makefile.  Use gzip instead
	of compress.  Link files individually instead of en masse;
	if a link fails, use `cp -f' on the losing file.

	* acspecific.m4 (AC_ALLOCA): Define CRAY_STACKSEG_END (the
	name of a function used in alloca.c) for CRAY-1, CRAY X-MP,
	and CRAY Y-MP.

Fri May  7 15:56:26 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_GETLOADAVG): Check for mach/mach.h, but don't
	disable nlist checks if found.

Fri May  7 04:59:25 1993  Noah Friedman  ([e-mail])

	* acspecific.m4 (AC_PROG_INSTALL): Don't look for `install' in
	/usr/ucb.

Thu May  6 20:41:35 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_FUNC_CHECK): The test program should choke on
	#ifdef __stub___$1 as well.
	(AC_REPLACE_FUNCS): Make the test program choke on stubs.

Wed May  5 20:43:13 1993  Roland McGrath  ([e-mail])

	* autoconf.sh ($infile existence check): Fixed test for
	nonemptiness of $print_version to not always be true.

Wed May  5 17:22:42 1993  David J. MacKenzie  ([e-mail])

	* acgeneral.m4 (AC_PREFIX, AC_PROGRAM_CHECK), acspecific.m4
	(AC_PROG_INSTALL): If IFS wasn't set initially, give it a
	normal default value.  Happens on LynxOS (x86), says
	Pete Klammer <[e-mail]>.

Wed May  5 13:22:52 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4: Undefine the `shift' builtin.

	* acspecific.m4 (AC_PROG_YACC): Use AC_PROGRAMS_CHECK to check for
	both bison and yacc, instead of two AC_PROGRAM_CHECK uses.

	* autoheader.sh ($# -eq 0): Set var $tmpout to name of temp file,
	send stdout there instead of config.h.in.
	(just before exit): If $# -eq 0, then move $tmpout to config.h.in
	if $status -eq 0, or remove $tmpout otherwise.

	* acspecific.m4 (AC_STRCOLL): Rewritten to use a test program that
	verifies that `strcoll' does vaguely reasonable ordering.

Tue May  4 19:59:00 1993  Jim Meyering  ([e-mail])

	* acspecific.m4 (AC_LONG_DOUBLE): Don't explicitely echo
	`checking for long double'.

Mon May  3 22:04:35 1993  Jim Meyering  ([e-mail])

	* acspecific.m4 (AC_GETGROUPS_T): New macro.

Sat May  1 22:37:55 1993  Jim Meyering  ([e-mail])

	* acgeneral.m4 (AC_WITH): Fix reversed args to patsubst.
	Test $with_FOO, not $FOO.

Wed Apr 21 18:14:19 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_QUOTE_TOKEN): New macro.
	(AC_DEFINE_QUOTE): Use it.

Tue Apr 20 18:02:46 1993  Noah Friedman  ([e-mail])

	* acspecific.m4 (AC_DECLARE_YYTEXT): Guess name of lex output file
	and do AC_SUBST of `LEX_OUTPUT_ROOT'.
	Add `dnl' after calling some autoconf macros.

Mon Apr 19 15:46:24 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_MINUS_C_MINUS_O): Do each compile a second time
	after testing for the existence of the output.  Some compilers
	refuse to overwrite an existing .o file with -o, though they will
	create one.

	* acspecific.m4 (AC_DECLARE_YYTEXT): Changed lex input to two lines
	of "%%", not just one.

Sat Apr 17 17:26:12 1993  Jim Meyering  ([e-mail])

	* acgeneral.m4 (AC_COMPILE_CHECK): Don't print `checking for ...'
	message if first argument is empty.

	* acgeneral.m4 (AC_REPLACE_FUNCS): Print a message under --verbose.

	* acgeneral.m4 (AC_HAVE_LIBRARY): Use m4's patsubst and translit
	instead of running sed and tr at runtime.

	* acconfig.h: Add STACK_DIRECTION.

Wed Apr 14 17:08:47 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_ALLOCA): If we chose alloca.c, run a test
	program to define STACK_DIRECTION.

Mon Apr  5 19:02:52 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_LONG_FILE_NAMES): Put test inside a for loop on
	several directories: . /tmp $prefix $exec_prefix.  Define
	HAVE_LONG_FILE_NAMES iff long names win in all those directories.

Sun Apr  4 18:38:23 1993  Roland McGrath  ([e-mail])

	* Makefile.in (%.info): Removed pattern rule.
	(autoconf.info, standards.info): New rules.

Wed Mar 31 16:58:12 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_CONST): Rewrite first AIX XL C 1.02.0.0 test.
	Comment out bogosity in second AIX test.

Wed Mar 31 12:45:59 1993  Jim Meyering  ([e-mail])

	* acgeneral.m4 (AC_DEFINE): Put single quotes around definition
	that is echoed with --verbose.  AC_DEFINE(MVDIR, "$(libdir)/mvdir")
	was generating losing code.

Mon Mar 29 15:44:24 1993  David J. MacKenzie  ([e-mail])

	* acspecific.m4 (AC_STDC_HEADERS): Add a missing pair of [quotes].

Mon Mar 29 14:54:00 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_DECLARE_YYTEXT): Change sed regexp so it won't
	match other identifiers beginning with `yytext'.

Sat Mar 27 00:11:16 1993  Paul Eggert  ([e-mail])

	* acspecific.m4 (AC_CONST): Detect broken AIX XL C 1.2.0.0 compiler.

Thu Mar 25 19:54:50 1993  David J. MacKenzie  ([e-mail])

	* acspecific.m4 (AC_CONST): Remove single quotes from the C
	program; they produce shell syntax errors.

	* acgeneral.m4 (AC_DEFINE): Add a newline after "}" to prevent
	commands following on the same line of configure.in from
	generating shell syntax errors.

	* acgeneral.m4 (AC_COMPILE_CHECK): Use explicit return types
	to avoid warnings.
	(AC_TEST_CPP): Add parens to force redirection order.
	(AC_OUTPUT): Allow hostname to return bogus exit status.
	From Jean-loup Gailly <[e-mail]>.

	(autoconf.conf, %.conf): Use it.
	(editsh): New variable: sed command to replace @datadir@; also
	replace @M4@ with $(M4).
	(autoconf, autoheader): Use $(editsh) instead of explicit sed command.

Mon Mar 22 13:08:10 1993  Jim Meyering  ([e-mail])

	* acspecific.m4 (AC_CONST): IBM's /bin/cc under AIX-3.2 on an rs6000
	rejects attempts to modify *any* member of a struct that has a
	member declared like `const int *ap[2]'.

Wed Mar 17 18:08:30 1993  Noah Friedman  ([e-mail])

	* autoconf.sh, autoheader.sh (MACRODIR): Variable renamed to
	AC_MACRODIR.  Don't initialize it at runtime if it is already set
	in the environment.

	Updated usage string.

	* autoconf.texi: Documented --macrodir option and its effects for
	both scripts.

Tue Mar 16 09:10:48 1993  Jim Meyering  ([e-mail])

	* acspecific.m4 (AC_CONST): Sun's SC1.0 ANSI compiler (acc) won't
	increment a `const int *' pointer declared through a typedef.

Mon Mar 15 16:08:42 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_PARSEARGS): Grok `--verbose' flag; set verbose=yes.

Sun Mar 14 18:19:21 1993  Roland McGrath  ([e-mail])

	* acspecific.m4 (AC_PROG_INSTALL): Choose `installbsd' if we find
	it, in preference to `install'.

	* acspecific.m4 (AC_CONST): Add a check for `const int *foo' not
	allowing modification of FOO (not *FOO).

Fri Mar 12 15:27:53 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_OUTPUT_HEADER): Remove conftest.sh before
	creating it.

Thu Mar 11 12:57:53 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_DEFINE): Surround defn with { and }.

	* acgeneral.m4 (AC_OUTPUT_HEADER): Split up $SEDDEFS into smaller
	chunks, since some shells can't handle large here documents.
	We write several commands in config.status to create conftest.sed
	in pieces.

Mon Mar  8 14:40:53 1993  Roland McGrath  ([e-mail])

	* acgeneral.m4 (AC_WITH): Don't echo anything.
	Use the m4 patsubst fn instead of a run-time sed invocation to
	massage $1.

	* acspecific.m4 (AC_DIR_HEADER_CHECK): #include <sys/types.h>
	before the header we are testing.

	* acgeneral.m4 (AC_DEFINE): If $2 is empty, echo "defining $1 to be
	empty", rather than "defining $1 to be ".

	(AC_DIR_HEADER): Use it to test for each possible header file.

Tue Mar  2 01:06:25 1993  Noah Friedman  ([e-mail])

	* autoheader.sh: Don't use /p1/,/p2/ construct with sed---it's not
	portable.  Handle broken AIX sed that strips \n from hold space
	when it shouldn't.  From Jun Hamano <[e-mail]>.

Tue Mar 02 00:08:39 1993  Jim Meyering  ([e-mail])

	* acspecific.m4 (AC_CONST): Fix typo that caused spurious lossage

	* acgeneral.m4 (AC_QUOTE_HERE, AC_QUOTE_SED): Change the quote
	chars to { and } instead of nothing.  Then use {} (empty quotes) to
	separate the patsubst forms from the following dnl.  Otherwise the
	result of patsubst is pasted together with dnl and the result is
	seen as a single token.

	* acspecific.m4 (AC_MINUS_C_MINUS_O): Print msg saying what we are
	doing before we do it.

	* acgeneral.m4 (AC_PREFIX): Print out the choice made.

	* acgeneral.m4 (AC_DEFINE_QUOTE): Add dnl at end of line.

	* acspecific.m4 (AC_GETLOADAVG): Do changequote around listing of
	/dev/kmem and sed frobbing which needs to use [ and ].
