3 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
4 string for more reliable failure. Wrap the entire test that
5 causes the broken Solaris printf to dump core, in a subshell,
6 so the segmentation fault message is reliably suppressed.
7 Fix shell expansion errors by using /usr/ucb/echo always;
8 avoid an error on systems without it by another subshell.
9 Avoid m4 expansion of `$1'. Set the zeroth argument of the
10 subshell-$as_echo to `as_echo', for better error message.
12 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
14 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
15 `BASH_SOURCE' contain a newline, set them to empty, as they may
16 not be unset.
18 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
20 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
21 years and is too hard to maintain now. The last straw was
22 reported by Jerker Baeck in
23 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
24 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
25 * doc/autoconf.texi (Particular Functions): Move
26 AC_FUNC_SETVBUF_REVERSED from here...
27 (Obsolete Macros): ... to here. Say that it does nothing now.
28 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
29 Turn into (almost) a no-op.
31 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
32 (AC_C_VOLATILE):
33 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
34 These macros are obsolescent and new applications shouldn't need them.
35 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
36 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
37 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
38 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
39 (AC_FUNC_VPRINTF): Likewise.
40 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
41 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
42 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
44 * doc/autoconf.texi (Setting Output Variables): Mention that
45 @VAR1@VAR2 has unspecified behavior. Problem reported by
46 Ralf Wildenhues.
47 * NEWS: Mention this.
49 * Makefile.am: Put only a single '#' into the copyright notice,
50 so that it's also present in the output file. Standardize wording
51 in makefile copyright notices to match GNU coding standards.
52 * bin/Makefile.am: Likewise.
53 * doc/Makefile.am: Likewise.
54 * lib/Makefile.am: Likewise.
55 * lib/freeze.mk: Likewise.
56 * lib/autoconf/Makefile.am: Likewise.
57 * lib/autoscan/Makefile.am: Likewise.
58 * lib/autotest/Makefile.am: Likewise.
59 * lib/m4sugar/Makefile.am: Likewise.
60 * man/Makefile.am: Likewise.
61 * tests/Makefile.am: Likewise.
62 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
63 one-line file.
65 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
67 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
68 in the sed script that mangles the awk script: delete up to the
69 first exclamation mark only.
70 * tests/torture.at (Substitute and define special characters):
71 Test '!' too.
73 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
75 Rewrite config files generation: avoid quadratic growth in
76 the number of substituted variables by using awk instead of sed
77 for the bulk of the substitutions.
78 * NEWS: Mention this.
79 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
80 forbidden in the output (and thus input) file.
81 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
82 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
83 generate just one large awk script for substitutions,
84 eliminating much of the earlier complexity, while adding some
85 new complexity. Only expand the substitution templates at
86 configure time, for smaller configure script size. If
87 _AC_SUBST_FILES are used, test 'awk' for working getline support
88 at config.status time. If absent, interpolate through the
89 shell. The awk script was written with much help
90 from Paolo Bonzini and Paul Eggert.
91 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
92 (_AC_SED_FRAG_NUM): Likewise.
93 (_AC_SUBST_CMDS): Renamed from...
94 (_AC_SED_CMDS): ...this.
95 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
96 * tests/torture.at (Substitute a 2000-byte string): Also
97 substitute a line with 1000 words, and a variable with several
98 long lines.
99 (Substitute and define special characters): Test awk special
100 characters, and put substitution input strings `@foo@' in the
101 output, to test that no recursion happens; test several other
102 combinations from Paolo Bonzini.
104 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
106 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
107 that replaced echo with AS_ECHO where this wasn't necessary.
108 Problem reportd by Ralf Wildenhues.
109 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
110 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
111 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
113 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
115 * lib/freeze.mk (GREP): Removed, no need to initialize this.
117 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
119 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
120 that traditional Awk lacks 3-arg "split". It has it.
121 Mention that FS must be a single character, and a few other
122 99-byte limits of traditional Awk.
123 Mention that if (i in a) doesn't work with traditional Awk.
125 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
127 * tests/autotest.at (BSx641-newline in command):
128 (BS-BS-newline in command, BSx640-newline in command):
129 (Newline-CODE-BS-newline in command):
130 (Single-quote-BS-newline in command):
131 (Single-quote-newline-BS-newline in command):
132 Use printf '%s\n' instead of echo, for portability to hosts
133 where echo interprets backslashes. This will break on hosts
134 that lack printf, but for now let's assume all such hosts
135 are dead (if not, we should get reports of test failures).
137 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
139 'echo' has some portability problems, when given a first argument
140 with a leading '-', or when given any argument containing '\'.
141 Avoid using 'echo' in these cases.
142 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
143 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
144 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
145 * lib/autotest/general.m4 (AT_INIT): Likewise.
146 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
147 argument might be unportable.
148 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
149 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
150 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
151 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
152 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
153 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
154 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
155 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
156 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.

159 (AC_PROG_MAKE_SET): Likewise.
160 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
161 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
162 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
163 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
164 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
165 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
166 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
167 * bin/autoconf.as: Redo verbose flag implementation, as the old
168 scheme wouldn't work with AS_ECHO.
169 * lib/autotest/general.m4 (AT_INIT): Likewise.
170 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
171 Don't use ECHO_T, since ECHO_N is now reliable.
172 * lib/autotest/general.m4 (AT_INIT): Likewise.
173 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
174 rather than using a here-document to put the script into a file.
175 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
176 use AS_ECHO.
177 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
178 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
179 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
180 bug, but we might as well stop using ECHO_N and ECHO_C internally.
181 * lib/autotest/general.m4 (AT_SETUP): Likewise.
182 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
183 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
184 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
185 operand, as AS_ECHO requires. Avoid double file name expansion.
186 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
187 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
188 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
189 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
190 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
191 Double-quote strings that would otherwise contain M4 comments.
192 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
194 * configure.ac (AC_INIT): Bump to 2.61a.
195 * NEWS: Likewise.
197 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
199 Version 2.61.
201 * configure.ac (AC_INIT): Bump to 2.61.
202 * NEWS: Likewise.
204 * tests/autotest.at (Macro with backslash in a test title):
205 Comment out for now, as this tests neither fails nor passes
206 reliably. Problem reported by Ralf Wildenhues.
208 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
210 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
211 in previous change, which caused test failures.
213 2006-11-16 Stepan Kasal <kasal@ucw.cz>
215 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
216 code for --enable, --disable, --with, and --without to...
217 (_AC_INIT_PARSE_ENABLE): ... a new macro.
218 * doc/autoconf.texi (Package Options):
219 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
221 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

320 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
321 and Stepan Kasal <kasal@ucw.cz>
323 Handle special characters in test case titles correctly.
324 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
325 properly.
326 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
327 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
328 argument. Extend to check titles printed by ./micro-suite and
329 ./micro-suite -l and the title in micro-suite.log.
330 (Backquote in a test title,
331 Single-quote in a test title,
332 Double-quote in a test title): Don't expect failure anymore.
333 (Backslash in a test title): Put a non-whitespace character after the
334 backslash so that Bourne shells might actually see it as an escape
335 sequence.
336 (Brackets in a test title,
337 Pound in a test title,
338 Comma in a test title,
339 Quoted Macro in a test title,

344 Macro with backslash in a test title): New tests expected to fail.
345 * tests/torture.at (#define header templates): M4-quote this title in
346 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
347 The visible effect was a stray [] in the testsuite output.
349 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
351 * doc/autoconf.texi (Limitations of Builtins): Do not invoke

354 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
356 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
357 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
358 5363) simply issues a warning when dividing by zero at compile
359 time. Problem reported by Elias Pipping.
361 2006-10-26 Eric Blake <ebb9@byu.net>
363 * THANKS: Update.
364 * doc/autoconf.texi (Evaluation Macros): Improve the example to

392 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
393 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
394 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
395 reported by Nelson H. F. Beebe for Coreutils 6.4.
397 * tests/tools.at (autoconf --trace: user macros): Remove test
398 for tracing multiline macros, since m4 1.4.7a uses a different
399 way to number lines. Problem reported by Ralf Wildenhues.
401 2006-10-24 Stepan Kasal <kasal@ucw.cz>
403 * bin/autom4te.in (handle_m4): Do not redirect stdin to
404 /dev/null since the heuristics for interactive behaviour was
405 fixed in CVS m4.
407 * bin/autom4te.in: With --force, always refresh the output
408 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

471 * lib/autotest/general.m4 (AT_INIT): Quote parameters of
472 AS_VAR_* properly.
473 * tests/m4sh.at (AS_LITERAL_IF): New test.
475 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
477 (Imported from Automake.)
478 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
479 which incorrectly sets the mode of an existing destination
480 directory. In some cases the unpatched install-sh could do the
481 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
482 system. We hope this is rare in practice, but it's clearly worth
483 fixing. Problem reported by Alex Unleashed in
484 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
485 Also, don't bother to check for -m bugs unless we're using -m;
486 suggested by Stepan Kasal.
488 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
490 Import this change from Automake:
492 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

494 is enabled by default with gnu and gnits strictness.
495 Report from Bruno Haible.
497 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
498 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
499 gnu and gnits modes.
501 Import this change from Config:
503 2006-09-20 Ben Elliston <bje@gnu.org>
504 * build-aux/config.sub (score, score-*): New.
506 Import this change from Gnulib:
508 2006-09-16 Karl Berry <karl@gnu.org>
509 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
510 to avoid sectioning errors.
512 Import these changes from Texinfo:
514 2006-10-04 Karl Berry <karl@gnu.org>
515 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

518 (\lquoteexpand, \quoteexpand): new defs.
519 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
520 (\code): must use new \...Char values, since now ` is active.
522 2006-08-26 Karl Berry <karl@gnu.org>
523 * build-aux/texinfo.tex (\textdegree): New command.
525 2006-08-12 Karl Berry <karl@gnu.org>
526 * build-aux/texinfo.tex (error \box0): smaller font.
528 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

532 2006-10-13 Stepan Kasal <kasal@ucw.cz>
534 * doc/autoconf.texi (Autoheader Macros): Warn that the text
535 added to the template can get mangled.
537 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
539 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
540 include the default headers, and redefine obstack_chunk_alloc
541 and obstack_chunk_free. Fixes false failure with glibc.
543 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
545 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

555 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
557 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
558 the NonStop platform.
559 * doc/autoconf.texi (Posix Variants): Likewise.
560 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
562 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
563 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
564 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
565 Use a better substitute, by inspecting the output of "ls"
566 rather than just using ":".
567 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
568 rather than AS_EXECUTABLE_P, since we needn't worry about
569 non-regular files here.
571 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
572 due to configuration hassles with this. See Tonya Underwood's report
573 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

580 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
582 2006-10-11 Stepan Kasal <kasal@ucw.cz>
584 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
585 initialization which is not inherited through the environment
586 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
587 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
589 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
591 * doc/autoconf.texi (Limitations of Usual Tools): Describe
592 problems with mkdir -p -m.
594 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
596 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
597 comment about ac_cpp_err; it was incorrect, and anyway
598 ac_cpp_err is being removed below.
599 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
600 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
601 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
602 nobody uses it.
603 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
604 with werror_flag and conftest.err and so forth. This is more
605 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
606 and anyway the user shouldn't normally want to see this gorp logged.
607 Problem reported by Ralf Wildenhues.
608 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
609 empty, not 'no', since the rest of the code uses 'test -z'.
611 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
613 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
614 Use a single call to AC_DO_TOKENS rather than multiple, for
615 efficiency.
616 (_AC_LINK_IFELSE): Test that resulting file is executable.
617 Problem reported by mwoehlke in
618 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
620 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
621 than creating a file to use with test -x; this is much faster.
623 2006-10-02 Bruno Haible <bruno@clisp.org>
625 * lib/autom4te.in (Automake-preselections): Add
626 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
628 2006-09-27 Stepan Kasal <kasal@ucw.cz>
630 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
631 standard error, `experr' should be used, not `expout'.
633 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
635 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
636 fseeko testing program twice; just use the earlier result.
637 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
638 Set cache var to 'unknown' (not 'no') if leaving the macro unset
639 still doesn't let the program compile.
640 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
641 failed.
643 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
644 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
645 include it, without including anything else.
646 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
647 expressions.
648 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
650 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
652 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
653 `error.h', and include it, for a `error_at_line' prototype.
654 Use a nonempty format string in the link test.
655 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
656 for a declaration of wait3.
658 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
660 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
661 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
662 can apply to constants too, and that it checks for macro defns.
663 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
664 and simply cast the identifier to void. This handles structure
665 values. Problem reported by Ralf Wildenhues.
666 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
668 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

722 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
723 --error-output, to avoid warnings with M4 2.0.
725 2006-09-19 Stepan Kasal <kasal@ucw.cz>
727 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

740 the path at runtime.
742 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
744 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

754 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
755 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
756 for the existence of the directory at configure-time. That's
757 too late, anyway. Problem reported by Stefan Seefeld.
759 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
760 7.1.4 /usr/bin/posix/sh described by Tim Rice in
761 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
763 2006-09-11 Stepan Kasal <kasal@ucw.cz>
765 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
766 works with GNU M4 1.4.3 again; make the normalized form
767 match the current m4 message; fix the description.
768 * test/tools.at (autom4te cache): Adapt to the change.
770 2006-09-08 Paul Eggert <eggert@cs.ucla.edu>
772 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Add year_2050_test
773 to catch glibc bug 2821
774 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
776 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
777 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
778 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
779 assume C89.
781 2006-09-08 Stepan Kasal <kasal@ucw.cz>
783 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
784 preselections ...

797 by Dries Kimpe.
799 2006-09-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
801 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over

803 accept files with extension `.f'. For consistency, also prefer
804 xlf over f77.
805 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
806 from last patch.

840 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
841 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
842 programs should use their Gnulib counterparts.
843 * doc/autoconf.texi (Particular Functions): Likewise.
844 (Macro Names, testsuite Invocation): Replace uses of these
845 obsolete macros with uses of non-obsolete macros.

869 simplify the code.
871 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
873 Fix Lex library problem reported to us by Julio Garvia.
874 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
875 for the default, which the user can override.
876 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
877 deal with LEXLIB.
878 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
879 didn't work if some values were cached but not others. Test for
880 broken lex libraries like native ia64-hp-hpux11.22; see
881 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
882 work around the problem by preferring an empty LEXLIB to -lfl or
883 -ll. Let the user set LEXLIB='' to indicate no library needed.
885 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
886 * README: Likewise.
887 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

945 (po-check): Look for lib files even if not in CVS.
946 (copyright-check): Use $() not ``.
947 (maintainer-distcheck): Do not depend on changelog-check.
948 (my-distcheck): Depend on $(release_archive_dir)/$(prev-tgz).
949 Also check for -Wpointer-arith.
950 (WGET, WGETFLAGS, tgz-md5, tgz-sha1, bz2-md5, bz2-sha1):
951 (xdelta-md5, xdelta-sha1, tgz-size, bz2-size, xd-size, rel-check):

982 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
983 64-bit preprocessor ints. Check for static initialization of
984 long long. Remove unnecessary casts.
986 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
988 * doc/autoconf.texi (Particular Programs): Mention that
989 @INSTALL@ and @MKDIR_P@ may vary for different output files.
990 Reported by Alexandre Duret-Lutz.
992 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
994 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
995 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
996 Bill Northcott in
997 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
999 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
1001 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
1002 pacify insanely picky compilers. Problem reported by Eric Blake.
1004 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
1005 longer supported by Sun.
1007 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
1009 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
1010 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1011 -Wundef -Werror". Problem reported by David Fang in
1012 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1013 * doc/autoconf.texi (Header Templates, Default Includes):

1015 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
1016 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

1028 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1029 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1030 this.
1032 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1034 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1035 problems with arg script text that doesn't end in newline, and
1036 with '-e a...'. Problems reported by Ralf Wildenhues.
1038 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1040 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1041 check for libXt by a check for libX11.
1043 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1045 * doc/autoconf.texi (config.status Invocation): Adjust according
1046 to last change.
1048 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1050 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1051 --help' should mention that `--version' outputs configuration
1052 settings. Report by Bruno Haible.
1054 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1056 Fix test suite failures reported by Pierre in
1057 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1058 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1059 the compiler created a file "b.out" when it didn't create anything
1060 at all.
1061 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1062 Discard stderr too, when invoking the test script.
1064 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
1066 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
1067 in the restoring of the werror flag.
1069 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1071 * doc/autoconf.texi (Volatile Objects): Be even a little
1072 less skeptical about "volatile", after discussion with
1073 Bruno Haible on bug-gnulib.
1074 (Limitations of Usual Tools): Warn about sed stripping
1075 leading white space from text. From Bruno Haible.
1077 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1079 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1080 compiler complains about it, even if things works after the
1081 complaint. Problem reported by Peter O'Gorman.
1083 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1084 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1085 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1087 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1089 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1090 after -R regardless of host. Patrick Welche reports that this

1097 to match M4 1.4.5.
1099 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1101 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1102 under AC_C_VOLATILE.
1103 (Volatile Objects): Be a little less skeptical about what
1104 "volatile" means. Derived from thoughts by Ben Pfaff in
1105 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1107 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1109 * doc/autoconf.texi: Fix some typos.
1111 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1113 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1114 more globally, since the 2006-06-30 patch didn't suffice. Problem
1115 reported by Keith Marshall. Also, don't bother with builddir2,
1116 since it shouldn't be needed any more.
1118 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1120 * doc/autoconf.texi (Generic compiler characteristics):
1121 Document AC_COMPUTE_INT. Fix wrong statements on Default
1122 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1124 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1125 (_AC_COMPUTE_INT): Add obsoletion warnings.
1126 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
1127 AC_COMPUTE_INT.
1129 * NEWS: Document change.
1131 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1133 * doc/autoconf.texi (Volatile Objects): New section.
1135 * NEWS: Document previous change.
1137 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1139 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1140 Require that long long int be at least 64 bits wide. C99 requires
1141 this and enough programs depend on it so we should check for it.
1142 Bruno Haible reports in
1143 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1144 that long long int is 32 bits wide with some nonstandard compilers.
1145 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1147 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1149 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1150 to a nonexistent file, so that we don't have to worry about
1151 a local site configuration that doesn't use /usr/local.
1152 Problem reported by Keith Marshall in
1153 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1155 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1157 * doc/autoconf.texi: Be more consistent about using @acronym with
1158 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1159 quite right (it talked about "OSF/Tru64", even though the
1160 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1161 and it even mentioned "OSF 4"!) and at this point there's little
1162 reason to talk about OSF any more, since it died in 1994.
1163 (Specific Compiler Characteristics): Simplify example of
1164 negative-size array.
1165 (File Descriptors): Reorder to make the text flow better.
1166 Remove joke about "appreciate the various levels"; I didn't get it.
1167 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1168 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1169 (File Descriptors, Limitations of Usual Tools):
1170 Tone down the advice against renaming or removing open files.
1171 (Limitations of Usual Tools): Add a new section, on 'rm'.
1173 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1175 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1176 -lXt in LIBS, idea from Karsten Hopp; this was due since
1177 this change:
1179 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1180 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1181 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1182 (which belong to Xt, not X itself). See Debian bug 327655.
1184 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1186 * configure.ac (AC_INIT): Bump to 2.60a.
1187 * NEWS: Update.
1189 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1191 Version 2.60.
1193 * configure.ac, NEWS: Update.
1195 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1197 * config/texinfo.tex: Sync from upstream.
1199 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1200 quadrigraph correctly in traces.
1202 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1203 Fix typos.
1205 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1206 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1207 not defined.
1208 * doc/autoconf.texi (Changed Directory Variables): New node,
1209 to document the whole `datarootdir' business a bit better.
1210 * NEWS: Update.
1211 * tests/torture.at (datarootdir workaround): Extend test.
1212 Prompted by report by Alexandre Julliard.
1214 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1216 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1217 when using default mode of IBM C 6 for AIX. Problem and two-line
1218 fix reported by Larry Jones.
1220 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1222 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1223 about literal '${datarootdir}' if a definition is found in the
1224 output file.
1226 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1228 * NEWS: Use "M4" rather than "m4" when appropriate.
1229 Problem reported by Eric Blake.
1230 * doc/autoconf.texi: Likewise.
1231 Use @acronym around BSD, GCC, and GNU when appropriate.
1232 (Why GNU M4): Renamed from "Why GNU m4".
1233 (Redefined M4 Macros): Mention that Posix
1234 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1235 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1236 to int.
1238 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1240 * bin/autom4te.in (handle_output): Do not forbid the empty
1241 pattern.
1242 * tests/tools.at (autoconf: the empty token): New test.
1244 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1246 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1247 calls, so that we do not care whether they are LIFO or FIFO;
1248 in the m4_wrap, do not check which diversion is the topmost
1249 one, just check that the stack is balanced at the end.
1250 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1251 base diversion forever--pop the previous diversion before
1252 opening the new one; consequently, remove the m4_wrap call.
1253 * lib/autotest/general.m4 (AT_INIT): Likewise.
1254 * tests/m4sugar.at: Do not use
1255 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1257 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1258 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1260 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1261 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1262 Rework example of m4wrap token-pasting trouble so that it doesn't
1263 care whether it's LIFO or FIFO.
1264 Fix some "contrary to"s that are awkward in English.
1266 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1268 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1269 to `yes' instead of `int$1_t' if the type is found, for more
1270 consistent configure output (where $1 is the number of bits).
1271 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1272 Suggested by Bruno Haible.
1274 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1275 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1276 with system headers. Report by Bruno Haible.
1278 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1280 * config/config.guess, config/config.sub: Sync from upstream.
1282 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1283 in order to avoid picking up an older installed frozen m4sh.m4f.
1284 Besides an outdated shell startup, this could have been created
1285 by an earlier M4 version with incompatible frozen file format.
1287 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1289 * README: Recommend m4 1.4.4 instead of 1.4.3..
1290 * doc/autoconf.texi: Likewise.
1291 (Special Chars in Names): Say that $(.FOO) is portable, as
1292 suggested by Stepan Kasal.
1293 (Installation Directory Variables, Build Directories):
1294 (Automatic Remaking, Subdirectories, Fortran Compiler):
1295 (Making testsuite Scripts, Defining Directories):
1296 Quote variable usages better.
1297 (Making testsuite Scripts): Add clean-local rule to makefile
1298 snippet, by Eric Blake.
1299 (Installation Directory Variables): Fix table item font.
1300 Reword slightly to clarify. Generalize advice about
1301 not using special characters to include all file-related
1302 vars, not just VPATH.
1303 (Special Chars in Variables): Warn about special characters in
1304 $(srcdir) too.
1305 (Assignments): Clarify default-value example as suggested by
1306 Ralf Wildenhues in
1307 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1308 (Special Shell Variables): Note leading ./ or ../, as suggested
1309 by Eric Blake.
1310 (Limitations of Builtins): Under cd, warn about CDPATH.
1311 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1312 Ralf Wildenhues.
1314 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1316 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1317 `@var', for texi2html.
1318 (Systemology): Some more word wrapping, for DVI output.
1319 (autom4te Invocation): The short option for `--melt' is `-M',
1320 not `-m'.
1322 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1324 * doc/autoconf.texi: More formatting and English tweaks,
1325 many suggested by Ralf Wildenhues.
1326 Reword to avoid "@code{...}'s" and the like, since it's ugly
1327 with Emacs info mode. discontents -> woes.
1328 Put a few "will"s back. time stamp -> timestamp.
1329 side-effect -> side effect.
1331 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1333 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1334 Warn about $@ not persisting. Problem reported by Julien Danjou in
1335 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1336 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1337 Mention other special chars, too.
1339 2006-06-14 Eric Blake <ebb9@byu.net>
1341 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1343 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1345 * doc/autoconf.texi: Some systematic minor improvements, as
1346 follows. Use "makefile" when talking about makefiles
1347 generally (which might be named "makefile" or "Makefile" or even
1348 "foo.mk"), "Makefile" when talking about a specific makefile
1349 called "Makefile". This unclutters the text from weird quotes
1350 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1351 values" rather than "@var{foo}s" and similar constructs containing
1352 "}s". Use "Make rules" rather than "Makefile rules". Minor
1353 English-language improvements. Change the prefix "sub-" to "sub"
1354 and "re-" to "re".
1355 Put blank lines around examples more consistently.
1356 Avoid "rather" and "very" as intensifiers.
1357 Avoid "will" as an auxiliary.
1358 (Limitations of Make): Split this node into....
1359 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1360 (Leading _ in Macro Names, Backslash-Newline-Newline):
1361 (Backslash-Newline Comments, Long Lines in Makefiles):
1362 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1363 (obj/ and Make, make -k Status, VPATH and Make):
1364 (VPATH and Double-colon, $< in Explicit Rules):
1365 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1366 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1367 New nodes, resulting from splitup of Limitations of Make.
1368 All cross-references changed. Raise the top node from
1369 a section to a chapter, and all subnodes accordingly.
1370 Redo the introductory wording to match the new organization.
1371 (Installation Directory Variables): Use an example that is
1372 closer to what Autoconf actually does. Mention that VPATH's
1373 value should not contain metacharacters or white space.
1374 (Fortran Compiler): Fix a VPATH bug in an example.
1375 (Leading _ in Macro Names): Mention that this problem is no longer
1376 of practical concern.
1377 (VPATH and Make): Reword the advice to make it clearer
1378 that Autoconf and Automake support VPATH in non-GNU make, but
1379 many packages have bugs in this area.
1380 ($< in Explicit Rules): Refer to Build Directories rather
1381 than using a (non-VPATH-safe) example.
1382 (Automatic Rule Rewriting): Mention the sort of disaster that
1383 can ensue with Solaris-style rule rewriting with VPATH.
1385 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1387 * doc/install.texi (Compilers and Options): Weaken the
1388 suggestion to use GNU make for VPATH builds.
1390 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1391 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1393 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1394 in regular expression.
1396 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1398 * doc/autoconf.texi (Installation Directory Variables):
1399 Drop extra @samp from `@table @samp' item.
1400 (Limitations of Usual Tools): Comment fix.
1401 Do not nest @samp just to point to other table items.
1402 (Writing testsuite.at) <AT_CHECK>: The second argument to
1403 `@dvar' is already @samp'ed.
1404 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1405 do not use @var in the second argument.
1407 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1409 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1410 $as_shell.exe too. Problem reported by Andreas Buening in
1411 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1413 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1415 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1416 `unused variable' compiler warning, for `-Wall -Werror'.
1417 Reported by Jaap Haitsma in
1418 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1420 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1422 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1423 case the compiler dumps core. Problem reported for
1424 OpenServer 5.0.7 by Tim Rice in
1425 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1426 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1427 Likewise.
1429 2006-06-06 Tim Rice <tim@multitalents.net>.
1431 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1432 "ERROR" only shows up in "make check" output if there is an
1433 error.
1435 2006-06-06 Eric Blake <ebb9@byu.net>
1437 * tests/tools.at (automatically allowed tokens): Fix typo.
1439 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1441 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1443 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1444 typically overflows on x86 CPUs, even though the C standard
1445 requires otherwise.
1447 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1449 * configure.ac (AC_INIT): Bump to 2.59e.
1450 * NEWS: Update.
1452 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1454 Version 2.59d.
1456 * config/texinfo.tex: Sync from upstream.
1458 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1459 seen, invoke libtoolize with `--ltdl' argument.
1460 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1461 * NEWS: Update.
1462 Suggested by Eric Blake.
1464 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1466 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1467 reported by Ralf Wildenhues.
1468 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1470 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1472 * THANKS: Update.
1474 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1476 * doc/autoconf.texi: Modernize some of the references to Solaris.
1478 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1480 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1481 message issued by AC_REQUIRE.
1482 * tests/m4sugar.at: Check m4_require's error message.
1483 * tests/base.at: Check AC_REQUIRE's error message.
1484 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1485 to...
1486 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1487 AT_CHECK_M4.
1488 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1489 `expout' as the last parameter.
1490 * tests/tools.at: Adapt to the above change.
1492 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1494 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1495 information about race-free implementations of mkdir.
1497 2006-06-04 Eric Blake <ebb9@byu.net>
1499 * bin/autoreconf.in (help): Document M4 environment variable.
1500 * bin/autoconf.as (Usage): Likewise.
1501 * bin/autom4te.in (help): Likewise.
1502 * doc/autoconf.texi (autom4te Invocation): Likewise.
1504 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1506 * NEWS: GNU make now recommended for VPATH builds.
1507 Mention that some macros are now documented to be obsolescent.
1508 * doc/autoconf.texi:
1509 Prefer "current" to "modern" to describe
1510 currently-used (albeit perhaps old-fashioned) hosts.
1511 Mention which ancient features no longer need to be worried about.
1512 setgid -> set-group-ID
1513 setuid -> set-user-ID (these are the Posix terms)
1514 Fix some misuses of "only".
1515 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1516 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1517 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1518 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1519 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1520 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1521 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1522 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1523 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1524 Mention that these macros are obsolescent.
1525 (Installation Directory Variables): shall -> should
1526 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1527 Mention that it's now safe to use 3 and 4.
1528 (Limitations of Usual Tools): cp -r is now specified by Posix.
1529 Omit longwinded and obsolescent discussion of cp -f.
1530 Modernize discussion of expr, ls.
1531 (Limitations of Make): Modernize discussion of VPATH builds.
1532 Mention $? as a workaround in some cases.
1533 * doc/install.texi (Basic Installation):
1534 Mention "./configure; make; make install" first. Be more
1535 specific about why this file is generic. Remove unnecessary
1536 parens. Remove misleading "only". Remove obsolete advice
1537 about csh. Don't say "configure" takes awhile; say it
1538 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1539 and CC=c99 rather than CC=c89, as these are blessed by current
1540 Posix. Recommend GNU make if doing a VPATH build.
1542 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1544 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1545 examples involving shell prompts.
1547 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1548 and Paul Eggert <eggert@cs.ucla.edu>
1550 * doc/autoconf.texi (Here-Documents): Add details about the
1551 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1552 use "here-documents" instead of "here documents".
1554 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1556 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1558 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1560 * doc/autoconf.texi (File System Conventions): Warn about ":"
1561 anywhere in directory names.
1563 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1565 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1566 about quoting the case statement, just in case.
1567 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1568 was fixed in ksh93g; reported by Ralf Wildenhues.
1570 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1572 * doc/autoconf.texi (System Services): Do not document
1573 overriding EXEEXT via ac_cv_exeext=ext.
1574 (Particular Programs) <AC_PROG_MKDIR_P>:
1575 Document that ${MKDIR_P} understands --.
1576 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1577 comment.
1579 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1581 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1582 argument with leading hyphen. Problem reported by Paul Eggert.
1584 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1586 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1587 about quoting ac_try: quote all of it, if any of it seems suspicious.
1588 This means we don't have to worry about ${ or sed any more.
1589 Also, double-quote the case statement, to work around misuses via
1590 underquoting as reported by Ralf Wildenhues in
1591 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1592 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1593 undocumented and dangerous macro.
1594 Problem reported by Ralf Wildenhues in
1595 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1597 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1599 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1600 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1601 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1603 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1605 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1606 since evidently some packages rely on the old, broken behavior.
1607 Problem reported by Ralf Wildenhues in
1608 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1609 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1610 pre-2006-05-26 definitions, but leave in the comments that
1611 these macros are dangerous and should not be used.
1612 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1613 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1614 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1615 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1616 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1618 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1620 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1621 the use of 'tr', since this is our only use of 'tr'.
1623 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1624 and Paul Eggert <eggert@cs.ucla.edu>
1626 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1627 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1629 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1631 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1632 the output file in the `${datarootdir}' test.
1634 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1635 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1637 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1638 mention of `datarootdir' in the input file(s), but literal
1639 `${datarootdir}' in the output file, and we haven't warned yet,
1640 then warn as well: the user may have (erroneously) used
1641 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1642 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1643 * tests/torture.at (datarootdir workaround): Extend this test.
1644 * NEWS: Update.
1646 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1647 and Paul Eggert <eggert@cs.ucla.edu>
1649 * doc/autoconf.texi (autoheader Invocation): The first argument to
1650 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1651 alternatives and clear up the language a bit.
1653 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1655 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1656 ac_config_guess, ac_config_sub, ac_configure.
1657 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1658 Fix typo that prevented an unnecessary space from being removed.
1659 Problems reported by Ralf Wildenhues in:
1660 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1662 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1664 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1665 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1666 Don't use the term "thread-safe" to talk about mkdir race
1667 conditions, since the problem is more a process than a thread
1668 issue. Problem reported by Stepan Kasal in:
1669 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1670 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1671 the test for 'install' more closely. Look at MKDIR_P first.
1672 Look in the PATH, and at /opt/sfw/bin.
1673 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1674 Don't bother to try mkdir -p, since we already check mkdir --version;
1675 just look at the version number. (There's no easy way to check
1676 for race-free implementations.)
1677 * tests/tools.at (autoconf: subdirectories): Adjust to above
1678 changes, since MKDIR_P now might end in "/mkdir -p".
1680 * doc/autoconf.texi (autoheader Invocation): Mention that the
1681 first arg of AC_DEFINE_UNQUOTED must be a literal.
1682 Problem reported by Ben Pfaff in
1683 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1685 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1686 * doc/autoconf.texi (Special Chars in Variables): New section.
1687 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1688 (Installation Directory Variables): Quote $(datadir) better.
1689 (Limitations of Builtins): Describe some of eval's trickiness.
1691 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1692 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1693 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1694 in front of every arg, not just trailing args. Quote apostrophes.
1695 (_AC_EVAL_ECHO): New macro.
1696 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1697 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1698 removed.
1699 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1700 exposed by quoting of eval argument. Put the command on line line
1701 so it logs better.
1702 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1703 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1704 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1705 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1706 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1707 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1708 Use eval more safely.
1709 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1710 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1711 to be replaced.
1712 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1713 lines, exposed by quoting of eval argument.
1715 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1716 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1718 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1719 initialization of `ac_cv_exeext', do not override it if it was
1720 already set, unless it was set to `no', for compatibility with
1721 Autoconf-2.13, and comment this.
1722 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1723 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1724 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1725 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1726 Document that this test may be overridden by setting
1727 `ac_cv_exeext'.
1729 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1731 Revert these two patches:
1733 2006-04-06 Eric Blake <ebb9@byu.net>
1734 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1735 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1736 2006-04-01.
1738 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1739 Clean up _AC_COMPILER_EXEEXT* macros.
1740 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1741 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1742 ac_file to the name of the default output file and call
1743 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1744 initial `rm' of the candidate files...
1745 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1746 the same list in subsequent `rm' calls, and for the temporary
1747 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1748 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1749 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1750 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1751 no longer needed) by libtool. Make it a cache check.
1752 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1753 copied here by mistake.
1754 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1755 _AC_COMPILER_EXEEXT.
1756 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1757 _AC_COMPILER_OBJEXT directly.
1758 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1760 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1762 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1763 Fix description of how the buggy `sed' works.
1765 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1767 Sync from Automake:
1769 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1770 ENOLCK. Only mention `make -j' when applicable. Only raise
1771 fatal errors when `make -j' is involved. Improve error message.
1773 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1775 * doc/autoconf.texi (Here-Documents): We now know more about
1776 the variable expansion in here documents bug.
1777 Thanks to Tim Rice and Stepan Kasal.
1779 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1780 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1782 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1784 * tests/autotest.at (Multiline command from M4 expansion):
1785 No failure to be expected if the shell quotes newlines in
1786 commands in the `set -x' output. Report by Tim Rice.
1787 * THANKS: Update.
1789 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1791 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1792 expansion in the here-documents used by config.status, as that
1793 runs afoul of the Korn shell version M-12/28/93d bug described in
1794 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1795 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1796 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1798 2006-05-23 Jim Meyering <jim@meyering.net>
1800 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1801 Fix typo introduced with 2006-04-02 change. It reversed the sense
1802 of the test.
1804 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1806 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1807 ac_dB slightly, to save bytes in the script.
1808 Max out at 50 lines, rather than 96; this is more likely
1809 (though not guaranteed) to avoid obscure 'sed' failures.
1811 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1813 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1814 `tr -d -' as bad option argument. Work around this by deleting
1815 an unrelated character.
1816 Report by Tim Rice <tim@multitalents.net>.
1818 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1819 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1820 Stepan Kasal <kasal@ucw.cz>
1822 * doc/autoconf.texi (Particular Programs): Do not promise that
1823 we always prefer the GNU version of the program, and that we
1824 search according to PATH; both rules can have exceptions.
1825 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1826 AC_PROG_SED. Move descriptions of limitations
1827 to the Limitations of Usual Tools section.
1828 (Limitations of Usual Tools) <sed>: Mention script length
1829 limitations with Solaris /usr/ucb/sed.
1830 <grep>: Fix wording for empty alternative. Mention that -c and
1831 -l should not be combined, and that -E and -F should not be
1832 combined.
1834 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1835 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1837 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1838 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1840 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1842 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1843 AC_DEFINE is now passed to m4_pattern_allow.
1844 * NEWS: Mention that; likewise for AC_SUBST.
1845 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1846 the parameter to m4_pattern_allow.
1847 * tests/tools.at: Add a check for that.
1849 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1851 * lib/autoconf/status.m4: Fix typos.
1853 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1855 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1856 only the files that this macro generates.
1858 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1860 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1861 the HP-UX sed limitation of 99 commands, labels do not count.
1862 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1863 in the comment.
1864 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1866 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1868 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1869 Import the following fix from coreutils:
1871 2006-01-13 Jim Meyering <jim@meyering.net>
1873 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1874 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1875 not double-quote uses of that variable, to accommodate the rare
1876 case in which getmntent is available in none of the libraries
1877 checked. This happens at least on FreeBSD 5.0.
1879 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1881 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1882 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1883 some other programs unwisely rely on these undocumented vars.
1884 But put in warning comments about them.
1885 Problem reported by Ralf Wildenhues in
1886 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1887 * NEWS: Document that these variables are intended to go away.

1891 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1892 and set the language to C++ (analogous to the equivalent Fortran
1893 tests).
1895 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1896 * doc/autoconf.texi (C++ Compiler): Document it.
1897 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1898 * NEWS: Update.
1900 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1902 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1903 that caused config.status to generate 100-command sed scripts; the
1904 portable limit is 99.
1906 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1908 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1909 variable `ac_d' instead of `d' to avoid infringing namespace.
1910 Report by Ralf Menzel.
1912 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1914 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1915 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1916 * tests/tools.at (autoconf: subdirectories): New test, taken from
1917 the corresponding problem report by Ralf Wildenhues in:
1918 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1920 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1921 Quote some uses of shell variables if they might suffer unexpected
1922 globbing. This doesn't fix all instances of quoting problems that
1923 I found, just the easy ones that look safe.
1924 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1925 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1926 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1927 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1928 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.

1933 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1935 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1937 * bin/autoreconf.in ($help): Reword according to the manual.
1938 Suggested by Olly Betts.
1940 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1941 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1943 * bin/autoreconf.in: Pass the directory argument to
1944 `require_configure_ac'. Fix comment.
1945 * tests/torture.at (Configuring subdirectories): Expose this.
1946 Reported by Olly Betts.
1948 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1950 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1951 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1952 Automake as follows:
1954 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1955 `$configure_in' instead of `configure.in', to preserve
1956 directory component.
1958 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1960 * config/config.guess, config/config.sub, config/texinfo.tex,
1961 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1963 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1965 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1966 test for C99 conformance; (bool) 0.5 is an integer constant
1967 expression, but (bool) -0.5 is not. Problem reported by Fedor
1968 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1970 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1972 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1973 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1974 Warn about obsolete install-sh files. Remove stray sentence
1975 fragment and fix cross reference.
1976 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1977 install -d; this undoes the 2006-05-10 change.
1978 (MKDIR_P): Mark with AN_MAKEVAR.
1979 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1980 that we don't require $INSTALL to be thread-safe. Move comments
1981 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1982 of AC_PROG_INSTALL. Output a message saying that we're checking
1983 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1984 MKDIR_P instead of AC_SUBST.
1985 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1986 Special magic for MKDIR_P, too.
1987 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1988 a dnl.
1989 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1991 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1993 Sync from Automake, as follows:
1995 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1996 * config/install-sh: Initialize IFS, so field splitting isn't
1997 turned off later.
1998 * config/mkinstalldirs: Likewise.
1999 * config/missing: Remove superfluous quotes. Replace all uses of
2000 `[' by `test', for consistency, and for..
2001 * config/missing (sed_minuso, sed_output): New variables.
2002 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2003 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2004 Fixes `missing' to detect `--output' for help2man. Fixes
2005 PR automake/483. Report by Dennis J. Linse.
2006 (autom4te): Document in `missing --help'.
2008 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2010 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2011 * config/install-sh: Don't use 'path' to talk about file names,
2012 as per GNU coding standards. Close a race condition reported by Ralf
2013 Wildenhues and Stepan Kasal. There is still a race condition
2014 on hosts that predate Posix 1003.1-1992, but we can't help this.
2015 Don't mishandle weird characters like space on pre-Posix hosts.
2016 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2017 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2018 AC_PROG_MKDIR_P from AS_MKDIR_P.
2019 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2020 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2021 earlier editions are not (including Automake 1.8.3).
2022 Do not suggest mkinstalldirs for thread-safety.
2023 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2024 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2025 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2026 presence of special characters and race conditions.
2027 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2028 in Autoconf's name space.
2030 2006-05-10 Bruno Haible <bruno@clisp.org>
2031 and Paul Eggert <eggert@cs.ucla.edu>
2033 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2034 from Automake with minor changes.
2035 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2037 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2039 * config/install-sh: Update to Automake CVS version, as follows:
2040 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2041 * lib/install-sh: Simplify the expr implementation of dirname.
2042 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2043 * lib/install-sh: Handle --, and diagnose unknown options.
2045 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2047 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2048 `./autom4te' to create `./testsuite', since the `all' target
2049 will ensure its presence, but `installcheck' should not create
2050 the uninstalled wrappers.
2052 * tests/torture.at (Unusual Automake input files): Skip if we
2053 detect automake < 1.8.
2055 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2057 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2058 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2059 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2060 * NEWS: Update.
2062 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2064 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2065 munge (multiple) white space and other oddities.
2066 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2067 single quotes in variable assignment.
2068 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2069 and similar failures by adding multiple spaces, tabs, and other
2070 special characters.
2071 Report and different test suggested by Francesco Romani
2072 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2074 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2075 single quotes, we only need to search for single quotes; this
2076 both simplifies the search pattern, and makes us less
2077 susceptible to `echo' variations for arguments not containing
2078 single quotes.
2079 (_AC_ARG_VAR_VALIDATE): Likewise.
2081 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2083 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2084 `$*' and IFS concatenation issue with traditional shells and
2085 bash-2.04. Report by Seanster@Seanster.com.
2087 2006-05-03 Bruno Haible <bruno@clisp.org>
2089 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2090 precisely which Mac OS X versions have the od problem.
2092 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2094 * doc/autoconf.texi: Use @option systematically.
2096 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2097 and Bruno Haible <bruno@clisp.org>
2099 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2100 about 'od'.
2101 (Integer Overflow): Mention the special case of integer division
2102 overflow.
2104 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2106 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2107 traditional shells like the Solaris one that do not use the
2108 first IFS character for assembling `$*'.
2109 Prompted by a related report from autoconf_bug@nro.ca.
2111 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2112 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2114 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2115 Mention more problems with the -e option.
2117 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2119 * NEWS: Typo.
2120 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2122 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2123 in URLs to improve DVI formatted output (requires texinfo 4.6).
2124 (System Services, Systemology, Shellology): Likewise.
2125 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2126 output.
2128 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2129 continuous text.
2130 (Runtime): Fix macro argument names to match description:
2131 `action-if-found' -> `action-if-true' and similarly.
2132 (Obsolete Macros): Likewise.
2133 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2134 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2135 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2137 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2139 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2141 * ChangeLog: Typo.
2142 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2143 DVI output.

2154 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2155 (Integer Overflow, Null Pointers, Buffer Overruns):
2156 (Floating Point Portability, Exiting Portably): New sections.
2157 (Writing Test Programs): Fix some langauge. Recommend exiting
2158 with status 1, not merely nonzero. Clarify exit declaration.
2159 (Run Time): Move C exit status stuff to new Exiting Portably section.
2160 (Systemology): Mention Posix and levenez. Update v7 reference.
2161 (Portable Shell): Mention the Posix shell.
2163 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2165 * bin/autoconf.as (me): Replace by as_me.
2167 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2169 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2170 since as_me isn't set yet.
2172 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2174 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2175 a few minor bugs in this area.
2177 * doc/autoconf.texi (Programming in M4sh): Comment out the
2178 documentation of AS_BASENAME, for now.
2179 (Shell Substitutions): Do not use AS_DIRNAME in an example.

2181 AS_BASENAME.
2182 * bin/autoconf.as (me): Don't use AS_BASENAME.
2183 (dir): Remove the unused variable.
2184 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2185 AS_DETECT_REQUIRED. All uses changed.

2191 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2192 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2193 (_AS_DIRNAME_PREPARE): Likewise.
2194 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2195 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2196 (AS_DIRNAME): Use "dirname --".
2198 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2200 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses

2210 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2212 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2213 Archive is not officially `GNU' any more. Update URL.
2214 (Defining Directories): Likewise
2215 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2217 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2219 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2220 newline from the `trap' code to finish `config.log'; the NetBSD
2221 /bin/sh resets the exit status after an empty command, as
2222 documented in doc/autoconf.texi.
2223 Reported by Dalibor Topic <robilad@kaffe.org>.
2225 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2227 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2228 Suggested by Bruno Haible.
2230 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2232 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2233 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2234 Instead, just list the shells that we know work.
2235 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2236 changed. Be more cautious about the _cv_ variable.
2237 * tests/tools.at (Syntax of the shell scripts): Check the
2238 _cv_ variable once, at first, to avoid an internal autoconf error
2239 when sh -n does not work.
2241 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2243 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2245 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2247 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2248 use ">&-" since we're only 99.999% sure that this is portable,
2249 and since the MinGW bug is fixed in a different way.
2250 * lib/autotest/general.m4 (AT_INIT): Likewise.
2252 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2254 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2255 before opening config.log, to avoid hitting a bug on MinGW.
2257 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2259 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2260 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2261 This works around a MinGW bug reported by Eric Paire.
2262 Make sure that all writes to the log file append to it,
2263 rather than possibly losing data.
2264 * lib/autotest/general.m4 (AT_INIT): Likewise.
2266 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2268 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2269 description.
2271 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2273 * NEWS: Update.
2275 * configure.ac (AC_INIT): Bump to 2.59d.
2277 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2279 Version 2.59c.
2281 * Makefile.maint (news-date-check): Do not require a leading `*'
2282 before the release date in NEWS.
2284 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2285 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2287 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2288 the instantiated file do not contain the string 'datarootdir'
2289 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2290 @mandir@, replace the reference '${datarootdir}' by the value.
2291 * tests/torture.at (datarootdir workaround): New test.
2292 * NEWS: Advertise this temporary fixup.
2293 Based on a patch by Bruno Haible, reported and analyzed by
2294 Paul Eggert and Noah Misch.
2296 2006-04-12 Eric Blake <ebb9@byu.net>
2298 * tests/autotest.at (Debugging a failed test): Fix comment.
2300 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2302 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2303 all the changes since 2006-04-07.
2305 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2307 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2308 succeeded, but `ln -s file dir' failed, take care to remove the
2309 leftover target before the next test, to prevent its spurious
2310 failure; also make sure `ln file dir' works before selecting it.
2311 Thanks to Keith Marshall for pointing this out.
2312 * THANKS: Update.
2314 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2315 assignments in `at_debug_args', so that we put them correctly
2316 in the `run' script.
2317 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2318 Reported by Eric Blake.
2320 2006-04-11 Eric Blake <ebb9@byu.net>
2322 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2323 top-level tests after micro-suite has been run. Used in...
2324 (Debugging a successful test, Debugging script and environment),
2325 (Debugging a failed test): ...these new tests. The first of these
2326 is fixed by...
2327 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2328 macro, split out from...
2329 (AT_INIT): ...here, so that using -d also generates a run script.
2330 Document that -d inhibits top-level logging.
2331 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2332 inhibits top-level logging; debug scripts are created.
2334 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2335 check.
2336 * tests/autotest.at (Empty test, Empty check): New test to check it.
2338 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2339 from gcc.
2341 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2343 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2344 the files if a problem appears. Make the empty *.at files
2345 read-only, too. Proposed by Ralf Wildenhues.
2347 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2349 * config/Makefile.am: Add comment to force updated Makefile.in.
2351 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2352 space only patch to this file, this patch causes the Makefile.in
2353 files that include freeze.mk to be updated, and thus have a
2354 newer time stamp again, which in turn makes a pristine CVS
2355 checkout have correct time stamps.
2357 * Makefile.maint (cvs-sv): New macro, to be used..
2358 (config.guess-url_prefix, config.sub-url_prefix)
2359 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2360 point to CVS text checkout of Gnulib files.
2361 (copyright-check): Bump current year.
2362 (announcement): Do not hard-wire `./announce-gen'.
2363 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2364 correctly.
2365 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2366 `chmod +x'.
2367 (wget_files): Update config.guess, config.sub, texinfo.tex by
2368 `wget-update', now that their URLs work again.
2370 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2372 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2373 Problem noted by Paul D. Smith.
2375 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2377 * doc/autoconf.texi: Remove unused words from word list.
2378 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2379 .x-sc_trailing_space: New files.
2381 * doc/standards.texi: Sync from gnulib.
2383 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2384 `LIBOBJDIR' as experimental.
2386 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2387 with a target directory; it's internally implemented as `cp'
2388 anyway, but since Autoconf advertises the possibility to use
2389 a target directory when LN_S is `ln -s', we need to find out.
2390 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2391 analyzed by Keith Marshall <keith.marshall@total.com>.
2393 * THANKS: Update.
2395 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2397 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2398 confdefs.h as-is. In general, if it has backslash-newline or the
2399 like, then it doesn't work either to sort or to remove empty
2400 lines.
2402 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2404 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2406 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2408 * lib/autom4te.in (Automake-preselections): Preselect
2409 _AM_SUBST_NOTMAKE.
2411 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2413 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2414 apostrophe within a single-quoted string, as this is the usual
2415 tradition and is easier to read than '"'"'. Don't rely on the
2416 shell treating "$/" like '$/'. Use a more-consistent indenting
2417 style for the trap.
2419 2006-04-09 Eric Blake <ebb9@byu.net>
2421 * tests/autotest.at (Backquote command substitution),
2422 (Multiline backquote command substitution): Remove mistaken
2423 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2424 applied...
2425 (Parenthetical command substitution, Multiline parenthetical
2426 command substitution): here.
2428 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2430 Import macros from gnulib (often changing their name).
2432 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

2444 (Pointers): Add Gnulib URL.
2445 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2446 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2447 Gnulib section.
2448 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2449 suggest a #define rather than a typedef for _Bool, and mention
2450 Gnulib rather than trying to substitute stdbool code.

2452 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2453 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

2456 headers too.
2457 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2458 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2459 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2460 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2461 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2462 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2463 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2464 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2465 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2466 (Coding Style). Don't mention m4_expand_once.
2467 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2468 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2469 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
2470 (AC_CHECK_FUNCS): Use it.

2475 (AC_HEADER_ASSERT): New macro.
2476 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2477 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2478 Catch a bug in an HP-UX C compiler.
2479 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2480 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2481 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
2482 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):

2484 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2485 New macros.
2487 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2488 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2490 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2492 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2493 of the warning introduced by the 2001-08-28 change.
2495 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
2496 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2498 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2499 variables shall be overriden by the cache.

2501 that contains braces.
2503 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2505 Revert the patch from 2006-04-01 and only improve
2506 _AS_DETECT_BETTER_SHELL:
2508 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2509 skip nonexistent directories.
2510 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2511 only shell candidates which exist.
2512 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2513 * lib/autotest/general.m4 (AT_INIT): No need to give three
2514 parameters to _AS_PATH_WALK.
2516 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2517 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2519 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2520 distinguish m4sugar macros.
2521 * tests/tools.at (autoupdating with aclocal and m4_include):
2522 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2523 test case by Noah Misch <noah@cs.caltech.edu>.
2525 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2527 Revert my change from 2006-03-17, in other words:
2528 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2529 and DUALCASE=1.
2530 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2531 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2532 it is set.
2534 2006-04-07 Eric Blake <ebb9@byu.net>
2536 * doc/autoconf.texi (Programming in M4sh): Document that
2537 AS_MKDIR_P exits the script on failure.
2538 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2540 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2542 * config/elisp-comp, config/install-sh, config/mdate-sh,
2543 config/missing, config/mkinstalldirs: Sync from Automake.
2545 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2546 from Automake.
2548 * doc/make-stds.texi: Sync from gnulib.
2550 2006-04-06 Eric Blake <ebb9@byu.net>
2552 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2553 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2554 2006-04-01.
2556 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2557 Eric Blake <ebb9@byu.net>,
2558 Paul Eggert <eggert@cs.ucla.edu>,
2559 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2561 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2562 whether `set' quotes correctly: redirect stderr of the tested
2563 `set', and use a subshell, for Ultrix; use `sed' instead of
2564 `grep' for zsh `set' which may write binary output; match only
2565 at the beginning of a line, to avoid false positives.
2566 In order to avoid false positives by unrelated variables with
2567 multiline content, put the dump algorithm in a subshell and
2568 unset all variables containing newlines (except some which are
2569 special to the shell). Warn about cache variables that are
2570 unset.
2572 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2574 * config/config.guess, config/config.sub, config/texinfo.tex:
2575 Sync from upstream.
2577 * tests/mktests.sh: Reword comments.
2579 * tests/mktests.sh: Only skip internal macros starting with
2580 `_AC_' or `__AC_'. Noted by Stepan Kasal.
2581 Update exclusion lists for the test suite to this end:
2582 (AC_ARG_VAR): Do test this now.
2583 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2584 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2585 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2586 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2588 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2589 shell issue with double-quoted command substitutions of native
2590 commands.
2591 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2592 Marshall.
2594 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
2595 no file matches the glob, discard the warning, set `nullglob'.
2596 (syntax-check): Likewise.
2597 (sc_cast_of_x_alloc_return_value): Likewise.
2598 (sc_cast_of_alloca_return_value, sc_error_exit_success)

2600 (m4-check): Likewise.
2601 (sc_system_h_headers): Do not print rule on execution.
2602 (sc_tight_scope): Do not fail for non-existing `src' directory.
2603 (sc_changelog): Skip the Copyright footer.
2604 * lib/autoconf/lang.m4: Remove trailing space.
2606 * lib/autoconf/status.m4: More replacements to
2607 <tab><space> where this makes sense.
2609 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2611 * tests/Makefile.am (maintainer-check-posix):
2612 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2614 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2615 ac_config_<foo>s again, sometimes normalized, sometimes not.
2616 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2617 (AC_CONFIG_COMMANDS): Do not do so here.
2618 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2619 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2620 2005-07-25 rewrite. Noticed by Noah Misch.
2622 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2623 _AC_PRESERVE_HELP_ORDER, ...
2624 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2626 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2627 inside m4_expand_once; it is redundant.
2629 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2630 for --help from Cygnus `configure.'
2632 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
2634 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
2635 on a patch proposed by Ralf Wildenhues.
2637 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2639 * lib/autoconf/status.m4: Replace <space>''<tab> with
2640 <tab><space> where this makes sense.
2642 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
2643 Noah Misch <noah@cs.caltech.edu>
2645 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2646 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2647 * doc/autoconf.texi (Help Formatting): New node.
2648 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2650 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2652 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
2653 lib/autoconf/specific.m4, lib/autoconf/status.m4,
2654 lib/autoconf/types.m4, lib/autotest/general.m4,
2655 tests/mktests.sh, tests/torture.at: White space cleanup:
2656 remove some SPACE before TAB, or add quoting ('' or @&t@).
2658 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
2660 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
2662 2006-04-05 Eric Blake <ebb9@byu.net>
2664 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2665 empty test suite works.
2666 * tests/autotest.at (Empty test suite): Remove xfail.
2668 2006-04-05 Noah Misch <noah@cs.caltech.edu>
2670 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
2671 TAGS to ac_config_<foo>s.
2672 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2673 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2674 normalizing it, consistent it with previous releases.
2675 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
2677 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2679 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
2680 Use simplified args that Eric Blake originally suggested.
2682 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
2684 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
2685 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2686 Use 'comm' rather than N instances of grep; this also fixes a bug
2687 whereby substrings were incorrectly matched, causing us to not
2688 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2689 (exclude_list): Exclude empty macros.
2690 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
2692 Use awk rather than grep -E or egrep, to avoid
2693 portability problems with regular expressions containing newlines.
2694 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
2695 Switch from grep to awk syntax.
2696 (ac_exclude_script): Renamed from ac_exclude_egrep.
2697 (au_exclude_script): Renamed from au_exclude_egrep.
2699 2006-04-04 Noah Misch <noah@cs.caltech.edu>
2701 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences

2776 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2777 initial `rm' of the candidate files...
2778 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2779 the same list in subsequent `rm' calls, and for the temporary
2780 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2781 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2782 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2783 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

2863 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
2864 switch all of them on and of when necessary. Fixes the bug when
2865 m4sugar macros (e.g., m4_define) were expanded after the first
2866 automatic update (e.g., after AC_PREREQ or AC_INIT).
2868 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

3122 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
3123 newline for portability.
3124 * tests/torture.at (Torturing config.status): Also test 100

3585 Stepan Kasal <kasal@ucw.cz>
3587 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3588 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3589 make its content writable before removing it. Remove an errorneous

3616 suggested by Ben Elliston. Handle weird characters correctly.
3618 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3620 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3621 calls, so that the final expansion of this macro is shorter.
3622 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3623 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3624 the cleanup there. Use AS_VAR_* macros, to be more general.
3625 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3627 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3629 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3631 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3633 * doc/autoconf.texi (Configuration Headers): Add an index entry
3634 for AH_HEADER.
3636 2005-08-26 Pavel Roskin <proski@gnu.org>
3638 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable

3640 running xmkmf.
3642 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3644 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3645 The previous patch didn't work, so try a better one.
3647 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3649 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3650 in the example. Reported by Bruno Haible.
3651 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3652 "if $undefined_var;" succeeds with my shell.
3654 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3655 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3656 but change the m4_divert_text to m4_divert_once.
3658 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3660 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3661 Work around bug in Solaris /usr/xpg4/bin/awk.
3662 The bug is present in at least Solaris 8 through 10.
3664 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3666 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3667 some evil values and relying on the fact that $* concatenates the
3668 parameters by the first character from IFS.
3670 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3671 Stepan Kasal <kasal@ucw.cz>

3675 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3676 Update limitations about when to call AC_CONFIG_HEADERS.
3677 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3678 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3679 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3680 ``Configuration Actions''; fix their index entries.
3682 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3683 options correctly. Process N-M as M-N if M is smaller than N.
3684 Process ranges correctly so that N-N will run only N.
3685 Sort and uniquify the tests that will be run. If there is more
3686 than one test, reinsert the banners for the tests.
3687 * tests/autotest.at (Keywords): Unmark XFAIL.
3689 2005-08-23 Stepan Kasal <kasal@ucw.cz>

3692 before passing the macro name to AH_TEMPLATE.
3694 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3695 now opens log after option processing; in particular, --version
3696 and --help do not touch config.log.
3698 * Makefile.maint: Revert the change from 2005-08-12.
3700 2005-08-22 Stepan Kasal <kasal@ucw.cz>

3713 Prepend to LIBS, not append, in examples.
3715 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3717 When building in place, set srcdir="."; suggested by Tim Van Holder.
3719 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3720 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3721 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3722 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3723 does not mean "no --srcdir option".
3725 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3727 * tests/autoscan.at (autoscan): New file.

3736 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3737 add "2>&1"; gzip 1.2.4 prints help on stderr.
3739 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3741 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3742 was pushdef'ed twice while popped only once. Push it only once.
3743 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3745 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3747 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

3752 * Makefile.maint: Update from Bison.
3754 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3755 "<tab>" in comment, so that the point is understandable.
3757 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3759 Rewrite substantial part of lib/autoconf/status.m4.
3760 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3761 and CONFIG_COMMANDS are not processed in four separate loops.
3762 Instead, there is one main loop. This alows that the common code
3763 is expanded only once, thus config.status (and configure) is smaller.
3765 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3766 the AC_LIST_FILES and cousins macros are no longer used.
3768 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3769 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3770 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3771 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3772 contain the initialization, nor the for loop, nor the associated
3773 commands; all these go to ...
3774 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3775 _AC_OUTPUT_CONFIG_STATUS.
3776 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3777 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3778 (_AC_OUTPUT_FILE): The creation of the sed script ...
3779 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3780 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3781 _AC_OUTPUT_MAIN_LOOP.
3782 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3783 _AC_CONFIG_COMMANDS): Use ...
3784 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3785 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3786 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3787 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3788 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3789 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3790 ... new macros.
3791 (_AC_CONFIG_UNIQUE): Update.
3792 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3793 Replaced by this ...
3794 (_AC_LIST_TAGS): ... new common macro.
3795 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3796 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3797 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3798 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3799 this didn't belong to the `config commands' section.
3800 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3801 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3802 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3803 to the `config commands' section either.
3804 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3805 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3807 ... and many changes to the comments nearby.
3809 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3810 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3811 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3812 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3813 (#define header templates): The comment at the top of the generated
3814 header now includes the name(s) of the source file(s).
3816 Several unrelated small changes:
3818 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3819 parameter to AC_DIAGNOSE.
3820 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3821 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3822 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3823 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3824 with AU::AC_OUTPUT.
3825 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3826 in AC_OUTPUT doesn't double-quote it either.
3827 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3828 parameters.
3830 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3832 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3833 versions of Portland Group compiler produce single- and double-quoted
3834 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3835 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3837 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3839 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3840 This is a corrected version of yesterday's patch.
3842 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3844 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3845 path, too; insert a "===" to emphasize the line.
3847 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3848 ac_cv_build_alias to ac_build_alias.
3849 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3851 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3852 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3853 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3854 (AC_ARG_VAR): ... here.
3855 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3856 target_alias.
3858 Keep a list of all precious variables and process them with one simple
3859 for loop, instead of expanding all commands, or, OTOH, complicated
3860 processing of output of "set".
3861 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3862 variable names in new macro...
3863 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3864 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3865 a loop to assign all ac_env_* and ac_cv_env_* variables.
3866 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3867 to INIT_PREPARE.
3868 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3869 its value to shell variable ac_precious_vars and call
3870 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3871 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3872 _AC_ARG_VAR_VALIDATE.
3874 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3875 and the AC_SUBSTs ...
3876 (AC_INIT): ... here.
3878 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3879 the ac_subst_files section in config.log.
3881 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
3883 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

3888 * tests/c.at (C keywords): Test AC_C_TYPEOF.
3890 Fix problems reported by Nicolas Joly.
3891 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3892 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3893 They are generated by the Tru64 v5.1B shell.
3895 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3897 Fix my changes from 2005-07-01; reported by Noah Misch.
3898 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3899 description, the macro now accepts only a single tag.
3900 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3902 Fix cases when the varsions of Autoconf and Autotest don't match.
3903 Reported by Noah Misch.
3904 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
3905 at_top_builddir, for compatibility with older autotest.
3906 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3907 is not set, use at_top_builddir, for compatibility with older
3908 versions of autoconf.
3910 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3912 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3913 Problem reported by Patrick Welche.
3915 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3917 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3918 sed substitution command, so that we allow | in program prefixes
3919 and program suffixes. (& is a problem anyway; we're not fixing
3920 that here.)
3921 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3922 configure_input, top_builddir, srcdir, etc.
3923 * lib/autotest/general.m4 (AT_INIT): Likewise, for

3926 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3928 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
3929 for loop over config.site files using `set', to allow
3930 directory names containing IFS characters.
3932 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
3934 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3935 directories with weird names. Apparently some people like living
3936 on the edge. However, improve the test that "pwd" actually does
3937 report a name for the working directory.
3938 * NEWS: Remove the claim that we test for funny chars in dir names.
3940 2005-07-01 Stepan Kasal <kasal@ucw.cz>

3953 (Generic Functions): Mention the Gnulib project.
3954 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
3956 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3957 document to output the default config_* lists to config.status.
3958 Don't recognize option --file, if the functionality is not there.
3959 Likewise for --header; moreover, recognize --he and --h as shortcuts
3960 for --help in that case.
3962 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3963 matches the order of execution. No code changed.

3984 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3985 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3986 (AC_SUBST): Call it.
3987 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3988 the directory specific variables; but don't call it for configure_input.
3990 2005-06-28 Derek Price <derek@ximbiot.com>
3992 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3993 addition.
3995 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3997 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3998 directory have inherent problems with special characters like spaces,
3999 due to limitations in Make syntax. Problem reported by Alexandre
4000 Duret-Lutz.
4001 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4014 from Justace Clutter.
4015 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4016 variable into diagnostic. Make the diagnostic an error, not a warning,
4017 because we really don't support spaces and suchlike in dir names.
4018 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4019 Don't worry about backslashes in srcdir; it can't happen now.
4020 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4021 Simplify ac_optarg handling.
4022 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4030 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4032 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4033 that '\|' is not allowed in BREs; recommend using newline separated
4034 list of patterns instead of multiple -e options.
4036 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4038 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4042 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
4044 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4046 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4047 b, t, r, w commands require single space, while : cannot have any.
4048 (Special Shell Variables): Fix sed code this in the example.
4049 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4050 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4052 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4053 expand to the empty list. Don't use two pairs of m4_changequote,
4054 it's not necessary.
4056 2005-06-20 Derek Price <derek@ximbiot.com>
4058 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4060 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4062 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4063 * doc/autoconf.texi:
4064 Don't mention Solaris versions so much, if a
4065 problem is common to all extant versions of Solaris. Say "SunOS
4066 4" instead of "SunOS" for SunOS 4.
4067 (awk): Mention more of the limitations of traditional Awk.
4068 (cat): Don't talk about cat -v.
4070 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4072 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4073 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
4074 but the implementation is entirely different and is designed
4075 to be compatible with glibc strverscmp.
4076 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4078 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4079 on Mac OS X 10.4 reported by Peter O'Gorman in:
4080 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4081 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4082 Use shell builtins rather than 'expr', to work around expr bug.
4084 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4086 * doc/autoconf.texi: "filesystem" -> "file system".
4087 "behaviour" -> "behavior".
4088 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
4089 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4090 as per POSIX.
4091 * lib/m4sugar/m4sh.m4: Likewise.
4092 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
4093 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4095 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4096 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4097 to update the man page. That way, we don't have to check in new
4098 man pages every month.
4100 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4101 quotes and backslashes. Patch from Derek Price.

4108 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4110 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4111 -u, since it outputs chatter if the input files are the same.
4112 Problem reported by Ralf Menzel.
4114 2005-06-08 Derek Price <derek@ximbiot.com>
4116 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4117 renaming them since they are about to be redefined anyhow.
4119 2005-06-08 Derek Price <derek@ximbiot.com>
4121 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4122 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4123 Move m4_undefine to alphabetical order.
4125 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4127 * README: Recommend GNU M4 1.4.3 or later.
4128 * doc/autoconf.texi (Introduction): Likewise.
4129 Reword to avoid some formatting glitches.
4130 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4131 Clarify explanation of HP compiler bug.
4132 Redo example output tp match current CVS snapshot.
4133 Use @example.org in email addresses when the examples
4134 might get inadvertently cut-and-pasted into user code.
4135 Remove example of autom4te usage that doesn't seem to work now.
4136 Use modern AC_INIT (except when the example is meant to be
4137 shown with Autoconf 2.13).
4138 Update ksh info for Solaris 9 and later.
4139 KB -> kB.
4140 Modernize description of Automake versions a bit.
4141 Don't claim a future version of Autoconf is near.

4144 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4146 * doc/autoconf.texi: Add [] to examples, so that the manual
4147 follows its own advice about quoting better.
4148 Reword to avoid some formatting glitches.
4149 * doc/installt.exi: Reword to avoid some formatting glitches.
4151 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4152 Tru64 ksh pattern matching bug. Reported against Libtool by
4153 Albert Chin <libtool@mlists.thewrittenword.com> and
4154 Nicolas Joly <njoly@pasteur.fr>.
4156 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4158 m4_cdr of one-member list was [[]] (one-member list containing an
4159 empty string) instead of [] (an empty list. Callers were skewed to
4160 match this misbehaviour. As a consequence of this:
4161 - m4_foreach([x], [], [foo]) expanded to `foo', while
4162 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4163 This bug has been fixed:
4165 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4166 expand to an empty string; print error msg if called without
4167 an argument list.
4168 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4169 misbehaviour; handle [] and [[]] correctly.
4171 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4173 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
4174 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
4175 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4177 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4179 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4180 swallow records with more than 99 fields.
4181 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4182 parse the long line.
4184 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4186 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4187 swallow literals longer than 399. Reported by Ralf Wildenhues.
4188 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4189 to workaround this limitation.
4191 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4193 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4194 to gfortran, and make these the first two compiler names
4195 checked (following the general autoconf preference for gcc).
4197 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4199 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4200 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4201 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4203 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4205 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4206 expression of unbounded size when processing the --list
4207 option. This runs afoul of a limit of 399 bytes per regular
4208 expression on AIX. Problem reported by Ralf Wildenhues.
4210 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4212 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4213 * doc/autoconf.texi (Particular Headers): Reword example
4214 for multiline stdbool replacement.
4215 (Setting Output Variables): Reword text a bit. Don't
4216 give all the details about |#_!!_#|.
4217 Reword description of line replacement.
4219 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4221 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4222 now contain newlines, and substituted files must be referenced on
4223 a line alone; the sed scripts to substitute them are now very
4224 different.
4225 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4226 commands can be put in a sed script portably.
4227 * doc/autoconf.texi (Setting Output Variables): Document above
4228 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4229 use of multiline substitution.
4230 * tests/torture.at: No longer expect substitution of newline to fail.

4235 From Ralf Menzel (trivial change).
4237 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
4239 * tests/local.at: Don't attempt to check for negated character
4240 classes in shell scripts. The test was too brittle.
4242 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4244 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4245 * doc/autoconf.texi (Limitations of Builtins): Document this
4246 limitation.
4248 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4250 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4251 common code; used in many places in the tree.
4252 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4253 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4255 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4257 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4258 messages when ac_unique_file is not found.
4259 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4260 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4261 commands, for consistency with AC_MSG_ERROR and such.
4263 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4265 * bin/Makefile.am: Merge the two rules for creating scripts.
4267 2005-05-23 Stepan Kasal <kasal@ucw.cz>
4269 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make

4271 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
4273 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4275 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4276 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4277 (ac_top_builddir): ... this ...
4278 (ac_top_build_prefix): ... to this; the old name is also kept, for
4279 backward compatibility.
4280 (ac_top_builddir_sub): New variable, without the trailing slash,
4281 always nonempty.
4282 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4283 * doc/autoconf.texi (Configuration Actions): Rename
4284 ac_top_builddir to ac_top_build_prefix.
4285 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4286 at_top_builddir to at_top_build_prefix.

4289 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4291 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4292 of confdefs.h .
4294 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4296 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4297 argument to m4_foreach. I guess it was necessary in the past,
4298 but I think it's a no-op now.
4300 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4302 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4303 ``cat <<_ACEOF'' commands to one.
4304 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4305 * lib/autoconf/status.m4: On various places, use expr instead of
4306 ``echo|sed.''
4307 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4308 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4309 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4310 a range.
4311 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4312 the wrong patterns between ``case'' and ``esac.'' The previous
4313 code had false positives.

4317 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4318 as on 2005-05-02.
4319 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4320 Mention LIBOBJDIR.

4382 quoting rules. Problems noted by Stepan Kasal.
4383 Also, throughout this document, be more careful about white space.
4384 "blank", "white space", and "space" all have different meanings
4385 and we should be careful to say what we mean.
4387 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4389 Fix C++ related problems reported by Werner Lemberg.
4390 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

4436 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4437 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4438 comment and reduce m4_default([foo], []) to [foo].
4439 (m4_strip): Update the explanation.
4441 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4443 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4444 Remove core.conftest.* too; it's generated by Tru64 5.1.
4445 Problem reported by Jennis Pruett.
4446 * lib/autoconf/functions.m4
4447 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4448 Don't bother to remove core files; AC_RUN_IFELSE should do that
4449 for you.
4451 2005-04-19 Stepan Kasal <kasal@ucw.cz>

4521 ac_pwd, and quote srcdir.
4522 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4524 * doc/autoconf.texi: Fix some systematic formatting problems.
4525 ".)" needs a following @: if not at the end of a sentence, and
4526 similarly for "!)". "etc." should be preceded by a comma.
4527 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4529 2005-03-22 Bruno Haible <bruno@clisp.org>
4531 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4532 argument is often called 'build-aux'.
4534 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4536 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4537 macro AC_TRY_LINK is obsolete.
4538 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4539 `AC_CONFIG_FILES'.
4541 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4543 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4544 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4545 from a Common Lisp's `cl'.
4546 (AC_PROG_CXX): Behave according to the documentation: don't
4547 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4548 make the variable CCC precious; use `cl.exe', not `cl'.
4550 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4551 Alexandre Duret-Lutz <adl@gnu.org>
4553 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4554 /dev/null, as "configure" shouldn't read stdin, and this insulates
4555 us from problems (e.g., when testing for "cl"). Also, do this
4556 redirection before invoking "hostname" or "uname", and keep the
4557 original input stream available via...
4558 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4559 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4560 bother with "</dev/null" since it's now done at the top of
4561 'configure'.
4562 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4563 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4564 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

4569 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4571 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4572 newline if neither \c nor -n work, as that would output two
4573 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4575 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4577 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4578 This causes that any required macros inside will get before the if.
4579 * doc/autoconf.texi (autom4te.cache): A typo.
4581 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4583 Undo previous change, except keep the change to
4584 lib/autoconf/programs.m4 that replaced grep with shell
4585 pattern-matching. This is because net-snmp configure reads stdin.
4586 Reported by Noah Misch.
4588 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4590 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4591 from /dev/null, as "configure" shouldn't read stdin, and this
4592 insulates us from problems (e.g., when testing for "cl").
4593 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4594 before invoking "hostname" or "uname".
4595 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4596 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4597 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4598 "</dev/null" since it's now done at the top of 'configure'.
4599 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4600 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4601 Also, replace grep with shell pattern-matching, to save a process.
4603 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4605 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4606 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4607 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4608 compiler.
4610 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4612 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4613 grep -q isn't portable. Improve grep -s explanation.
4614 Problem reported by Dan Manthey.
4616 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4618 * doc/autoconf.texi (Special Shell Variables): Clarify
4619 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4621 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4623 * doc/autoconf.texi: Use @acronym for DJGPP.
4624 Fix some @code's that should have been @env's, and vice versa.
4625 Sort environment variable names.
4626 Mention that shells no longer inherit IFS.
4627 Don't recommend PATH_SEPARATOR=';' so strongly.
4628 Mention that $RANDOM might expand to the empty string.
4629 "symlink" and "soft link" -> "symbolic link".
4630 Improve mktemp description (reported by Bruno Haible).
4632 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4634 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4635 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4636 Likewise.
4637 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
4638 Likewise.
4640 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
4642 * NEWS: Mention AT_COPYRIGHT.
4644 * tests/local.at (AT_CMP): Use diff directly on input files rather
4645 than copying them.
4647 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4648 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4650 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4651 and Paul Eggert <eggert@cs.ucla.edu>
4653 * tests/autotest.at (Empty test suite): New test.

4658 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4660 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4661 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4662 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
4663 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
4664 (Standard regular expressions): New test.
4665 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4666 excess test name quoting.
4667 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4668 CPPFLAGS to `configure' instead of setting it in `configure'.
4670 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4671 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4672 on some platforms.
4674 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4675 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
4677 * tests/local.at (AT_CMP): New macro.
4678 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

4682 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
4683 * tests/c.at (Extensions): Do not exit early.

4703 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4705 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4706 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4708 Try not to generated lines of unlimited length, as POSIX places a
4709 2047-byte limit on line length of portable text files.
4710 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4711 Use newline as a separator, not space.
4712 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4713 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4714 space.
4716 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4718 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4719 as_func_*. Add test to check whether positional parameters
4720 are restored after function return.
4722 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4724 * doc/autoconf.texi (Special Shell Variables): Mention _,
4725 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4726 if they contain a lower-case letter. The DUALCASE problem was
4727 reported by Ralf Wildenhues.
4729 * bin/autoconf.as: Don't exit with status 0 after write failure
4730 with --help or --version.
4731 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

4736 * doc/autoconf.texi (Limitations of Usual Tools):
4737 Unicos 9 sed limitations.
4738 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
4739 to get the option-enhanced interface on older Crays. Try ftn for
4740 Fortran 95 (newer Crays).
4742 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4744 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4745 care to echo the commands, so the user knows what's going on.
4746 Modified from a suggestion by Stepan Kasal.
4748 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,
4749 with a cross reference. Derived from a suggestion by Bruce Korb.

4755 * doc/install.texi (Defining Variables): Likewise.
4756 Based on a proposed patch by Ralf Wildenhues.
4758 * man/Makefile.am (.x.1): Make sure the required generated files
4759 are up to date. Problem and original solution proposed by Stepan Kasal.
4760 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
4761 implicit-man-prerequisites): New rules, used by the above.

4767 2005-01-29 Stepan Kasal <kasal@ucw.cz>
4769 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4770 Update the long comment explaining it.
4772 m4_require no longer writes an ``is required by'' line to the
4773 execution stack. It contains only one bit of non-redundant
4774 information: that the macro was required, not called. And even
4775 this bit is useless in most situations: have you ever met a macro
4776 which both calls and requires the same macro?
4778 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4779 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4780 macro.
4781 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4782 (m4_expansion_stack_pop): Remove the misplaced comment.
4783 (m4_require): Don't put the ``is required by'' line to the
4784 execution stack; slightly improve the out-of-a-defun error message.
4785 (_m4_divert_grow): New macro, counter for the temporary diversions.
4786 (_m4_require_call): Use it.
4787 * tests/m4sugar.at (m4_require): Expect output without the
4788 ``is required by'' messages.
4790 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4792 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4793 rather than x for expr.
4795 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4796 this is safe.
4797 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4798 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4807 * doc/make-stds.texi, doc/standards.texi: Update from masters.
4808 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
4809 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4810 from masters, so that FileUtils.pm's update_file provide --force
4811 support.
4812 * bin/autoheader.in: Pass $force to update_file so that
4813 config.h.in is always recreated when --force.
4815 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4817 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4819 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4821 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4822 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4824 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4826 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4827 Warn about newline stripping in `` and $(). Update Solaris
4828 version to 9.
4829 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4830 X insulates us from future changes to Posix.
4831 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4832 stripping.
4834 2005-01-19 Stepan Kasal <kasal@ucw.cz>
4836 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
4837 you cannot use AC_DEFINE to define macros containing `[' or `]'.
4839 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
4841 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

4852 ulongval to be static, to avoid unwanted GCC warning. Problem
4853 reported by Michael Jennings via Daniel Reed; see
4854 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4856 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4858 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
4859 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
4860 datadir, infodir, and mandir. Adjust argument parsing code.
4861 (_AC_INIT_HELP): Update help text.

4863 new variables.
4865 2005-01-04 Noah Misch <noah@cs.caltech.edu>
4867 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
4868 not seem to work, assume it does set $(MAKE).
4869 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
4871 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4873 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

4879 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
4880 (_m4_divert_n_stack): New macro; the expansion is
4881 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4882 otherwise.
4883 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4884 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4885 stored in _m4_divert_diversion or _m4_divert_dump.
4886 (m4_divert_pop): When the parameter is given, compare the symbolic
4887 name with the last diversion pushed on the stack. Previously, the
4888 current diversion was compared with the numeric value of the
4889 diversion given as the parameter.
4890 (m4_require): If the macro hasn't been expanded yet, call ...
4891 (_m4_require_call): this new macro.
4893 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4895 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_ARG_VAR_VALIDATE):

4924 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
4925 signals that the package uses Automake; a `Makefile.am' is typical but
4926 not essential. Reported by Magnus Therning.
4927 * tests/torture.at (autoreconf.): New banner.
4928 (autoreconf and non-AC configure): Rename to `Non-Autoconf
4929 AC_CONFIG_SUBDIRS'.

5198 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

5317 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

5424 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5426 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5428 * lib/autom4te.in (Automake-preselections): Preselect
5429 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5430 trace them.
5432 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5434 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5435 Tru64.
5436 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5437 Document problem with "`""`" in pdksh POSIX mode.
5439 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5441 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5442 with pdksh, too. Problem reported by Patrick Welche via
5443 Gary V. Vaughan.
5444 * doc/autoconf.texi (Shellology): Note that set -o posix is
5445 useful for pkdsh, too.
5447 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5449 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5450 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5451 Don't fail if ENV or BASH_ENV is readonly.
5452 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5453 etc. are read only. Problem reported by Ludovic Courtes.
5455 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5457 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5458 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5459 (trivial change)
5461 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5463 * doc/autoconf.texi (File System Conventions): Warn about
5464 names like "aux". Problem reported by Eric Blake.
5466 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5467 by zero instead of array size, so that we can use any arithmetic
5468 constant expression (instead of requiring an integer constant
5469 expression). This allows us to test expressions like DBL_MAX <
5470 LDBL_MAX, which didn't conform to the C standard using the old
5471 method.
5472 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5473 now that we can do floating-point tests at compile time.
5475 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5477 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5478 and LDBL_EPSILON, as the resulting expression isn't an
5479 integer constant expression and violates the C standard.
5480 Problem reported by Nelson H. F. Beebe. Also, check
5481 for "L" suffix, and check that long double doesn't have
5482 worse range or precision than double, that mixed-mode
5483 arithmetic doesn't generate a diagnostic, that double
5484 constants fit in long double.
5486 2004-06-03 Kevin Ryde <user42@zip.com.au>
5488 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5489 malloc(0) and realloc(NULL,size).
5491 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5492 Bob Proulx.
5494 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5496 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5497 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5498 by Jim Meyering.
5500 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5502 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5503 can be rewritten using if-then-else. Suggested by Bruno Haible.
5505 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5507 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5508 Problem reported by Stepan Kasal.
5510 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5512 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5513 change). Patch reported by Ralf Wildenhues in
5514 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5516 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5517 function F exists if the compiler and linker let you compile an
5518 expression like (F != 0). Recent versions of GCC optimize away
5519 the reference to F in that case, since every function address must
5520 be nonzero, so the link succeeds even if F does not exist.
5521 Problem reported by Manu in
5522 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5524 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5525 "Unix". Many uses changed.
5526 (Limitations of Builtins): Explain better why the ! command isn't
5527 portable.
5529 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5531 * lib/autom4te.in (Automake-preselections): Preselect
5532 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5534 2004-05-19 Kevin Ryde <user42@zip.com.au>
5536 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5537 referencing AC_FUNC_STRERROR_R.
5539 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5540 note pessimistic assumption when cross compiling.
5542 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5544 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5545 (until 2004) invoked subcommands with sh -e, contra POSIX.
5546 Reported by Kevin Ryde.
5548 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5550 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5551 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5552 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5553 `test -f " /usr/bin/grep"', which _always_ failed.
5554 (AC_PROG_SED): Ditto bogus PATH fix.
5555 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5556 requires that grep correctly supports _multiple_ `-e' options, rather
5557 than stating only that grep should accept `-e'.
5559 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5561 Port to C99, which requires that 'exit' be declared.
5563 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5564 to ensure that stdlib.h is included.
5565 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5566 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5567 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5568 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5569 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5570 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5571 when using 'exit' in a test; C99 requires that 'exit' be declared.
5573 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5575 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5576 now prefers 'grep' implementations that accept -e.
5577 (Limitations of Usual Tools): Describe problems of traditional
5578 egrep and fgrep with long input lines, and of traditional grep
5579 with -e.
5580 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5581 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5582 All callers changed. Append /usr/xpg4/bin to the PATH, for
5583 Solaris.
5584 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5585 the user with complaints about multiple -e options.
5586 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5587 Define it with AC_PROG_GREP.
5588 * configure.ac (AC_PROG_GREP): Add.
5589 * lib/freeze.mk (GREP): New macro.
5591 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5593 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5594 a possible candidate only after all others fail, rather than
5595 consulting it first. This improves backward compatibility by
5596 better reflecting the way shell selection occurred in previous
5597 versions of Autoconf, and should help to avoid triggering latent
5598 problems in other packages, such as the one in Automake where zsh
5599 is not handled robustly:
5600 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5601 Although it is not Autoconf's responsibility to work around
5602 problems in Automake, it nevertheless makes sense to avoid
5603 introducing unnecessary incompatibilites.
5605 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5606 Gary V. Vaughan <gary@gnu.org>
5608 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5609 how deeply nested we are when a suitable tool is found, set the
5610 ac_path_TOOL_found flag.
5611 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5612 nested we are in this macro. Break out of all 3 nested loops if
5613 ac_path_TOOL_found is set.
5615 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5617 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5618 of the _AS_PATH_WALK loop too if GNU flavor is found.
5620 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5622 * doc/autoconf.texi (Limitations of Make): Update documentation
5623 for `$<'. New entry `Long lines', based on a report from Simon
5624 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5625 paragraph about DJGPP, based on a mail from Richard Dawe.
5627 2004-04-20 Paul Eggert <eggert@twinsun.com>
5629 * tests/c.at (C keywords): Don't assume that GCC supports
5630 "restrict" and "inline", as sufficiently-old GCC versions do not
5631 (also, GCC configured to be in pedantic C89 mode does not).
5632 Problem reported by Sumit Pandya in:
5633 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5635 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5636 consider -g to work if it generates warnings when plain compiles
5637 don't. Problem reported by Braden McDaniel in:
5638 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5640 * doc/autoconf.texi (Slashes): New section, to document a problem
5641 reported by Jim Meyering in:
5642 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5644 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5645 linker output files before linking, to work around IRIX 6 linker bug.
5646 Problem reported by Rainer Orth in:
5647 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5649 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5651 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5652 best tool so far counter rely on the tool path variable name to
5653 avoid checks for one tool being affected by the results of running
5654 the length check on a previous tool.
5656 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5657 match expression argument, as different greps have different
5658 regular expression flavours.
5659 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5660 literals.
5661 (AC_PROG_EGREP): Pass 'EGREP$'.
5662 (AC_PROG_GREP): Pass 'GREP$'.
5664 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5666 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5667 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5669 2004-03-29 Paul Eggert <eggert@twinsun.com>
5671 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5672 Types, Specific Compiler Characteristics, System Services,
5673 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5674 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5675 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5676 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5677 Likewise.
5678 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5679 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5680 AC_TYPE_OFF_T): Likewise.
5681 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5682 Likewise.
5684 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5685 pacify libtool 1.5.2. Fix quoting problems in sed command.
5687 2004-03-28 Paul Eggert <eggert@twinsun.com>
5689 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5690 now defines HAVE_DECL_TZNAME if it is declared, when
5691 HAVE_STRUCT_TM_TM_ZONE is not defined.
5692 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5693 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5694 for HAVE_TZNAME.
5696 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5698 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5699 superfluous backslashing of quotes (") in sed expressions;
5700 thanks to Paul Eggert.
5702 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5704 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5705 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5706 H. F. Beebe for the bug report.
5708 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5710 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5711 quoted -cmdline argument in Portland Group compiler (bug
5712 reported by Jeffrey J. Barteet).
5714 2004-03-25 Kevin Ryde <user42@zip.com.au>
5716 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5717 (Run Time): ... here, where it's now mentioned.
5719 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5721 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5722 inherits from language Autoconf-without-aclocal-m4.
5723 (Customizing autom4te): Adjust example; the cache must now be
5724 disabled for language Autoconf-without-aclocal-m4.
5726 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5727 Nathanael Nerode <neroden@twcny.rr.com>

5738 AC_CHECK_TOOLS.
5739 (Specifying Names): Document the reason for these future
5740 behavioral changes.
5741 * tests/mktests.sh: Do not generate tests for the
5742 new macros.
5743 * NEWS: Document these changes.
5745 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5746 they make TeX hang up.

5751 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5752 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5753 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5754 vowel.
5755 (AC_CHECK_ALIGNOF): New macro.
5756 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5757 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5758 those for sizeof.
5760 2004-03-03 Paul Eggert <eggert@twinsun.com>
5762 * bin/Makefile.am (edit): Don't use $< in a context where
5763 POSIX doesn't require support for it. Use $@.in instead.
5764 Problem reported by Anthony N. Frasso in
5765 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5766 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5768 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5770 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5771 from the next generation of Libtool.

5794 AC_SUBST provides no portable way to escape literal newlines.
5796 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5797 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5798 Darwin uses -lcrt2.o and there's little point to cataloging all
5799 the system variants. Partial fix reported by Andreas Waechter in:
5800 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5801 for bug reported by Nelson H. F. Beebe in:

5814 refer to the correct file.
5815 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5816 the behavior of the third argument.
5817 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5818 correctly the behavior of the third argument. Document
5819 what the three macros that AU_DEFUN defines do. Fix
5820 warning message when the third argument includes $0
5821 (reported by Alexandre Duret-Lutz).

5824 Eric Sunshine <sunshine@sunshineco.com>
5825 Paul Eggert <eggert@twinsun.com>
5827 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5828 (AS_INIT): Output shell initialization there. Removed optional
5829 parameter. Expand _AS_SHELL_FN_SPY.
5830 (AS_INIT_WITH_SHELL_FN): Removed.
5831 (_AS_SHELL_FN_SPY): New macro.
5832 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5833 macros.

5835 and documentation for the parameter.
5836 (_AS_DETECT_BETTER_SHELL): Move it here.

5838 (_AS_RUN): Move it here, support testing with eval.
5839 (AS_REQUIRE_SHELL_FN): Require shell functions when
5840 it is used.

5844 use AS_INIT_WITH_SHELL_FN.
5845 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5847 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

5875 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

5877 the 2003-05-22 change, which removed the older years from the list.
5878 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5880 2004-01-27 Gary V. Vaughan <gary@gnu.org>
5881 Albert Chin-A-Young <china@thewrittenword.com>

5884 grep or ggrep program in PATH that accepts as long lines as
5885 possible.
5886 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5887 AC_PROG_GREP.
5888 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5889 egrep and fgrep respectively if $GREP -E/-F don't work.
5890 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5891 _AC_PROG_GREP, and AC_PROG_SED.
5892 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5893 longest input length accepted by a command.
5894 (AC_PROG_SED): Use it.
5895 * doc/autoconf.texi (Particular Programs): Document the changes.
5896 * NEWS: Updated.
5898 2004-01-27 Paul Eggert <eggert@twinsun.com>
5900 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
5901 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
5902 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5903 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5905 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5906 bin/autoconf.in, config/Makefile.in, config/config.guess,
5907 config/config.sub, config/install-sh, config/mdate-sh,

5922 2004-01-26 Paul Eggert <eggert@twinsun.com>
5924 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5925 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5926 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5927 not <inttypes.h>. Problem reported by Tim Mooney in
5928 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5929 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5930 Likewise.
5932 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5933 otherwise "make check" fails because it forbids cmp (I guess
5934 because cmp treats files as binary on DOS-like systems).
5936 * tests/mktests.sh: Update copyright date to 2004, since some tests
5937 have changed in 2004.
5939 2004-01-23 Gary V. Vaughan <gary@gnu.org>

5942 non-truncating sed or gsed program in PATH.
5943 * tests/acprograms.at: Add it.

5945 * NEWS: Updated.
5947 2004-01-15 Paul Eggert <eggert@twinsun.com>
5949 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5950 -std1 disables some useful extensions on Tru64. Problem reported
5951 by N. Lichtmaier in
5952 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5954 2004-01-14 Paul Eggert <eggert@twinsun.com>
5956 * doc/autoconf.texi (Programming in M4sh): Document that
5957 AS_MKDIR_P succeeds if the destination is a symbolic link
5958 to an existing directory.
5959 (Limitations of Usual Tools): Note that mkdir -p might not
5960 succeed on symlinks to directories.
5962 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5964 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5965 * bin/autoheader.in: Grammar fix in message.
5966 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5967 Test for dir before calling mkdir -p. (trivial changes)
5969 2004-01-13 Eric Blake <ebb9@byu.net>
5971 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5972 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5974 2004-01-10 Jim Meyering <jim@meyering.net>
5976 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5978 2004-01-09 Paul Eggert <eggert@twinsun.com>
5980 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5981 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5982 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5983 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5984 AC_COMPILE_IFELSE, since we now assume our caller invokes
5985 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5986 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5987 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5988 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5990 2004-01-07 Paul Eggert <eggert@twinsun.com>
5992 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5993 `"'...'"`, as it's confusing (and I suspect it may not work on
5994 some platforms). The code was incorrect anyway, as it assumed
5995 that \$ evaluated to itself in that context. Reported by
5996 Alexandre Duret-Lutz.
5998 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6000 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6001 and _LT_AC_TAGCONFIG.
6003 2004-01-06 Paul Eggert <eggert@twinsun.com>
6005 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6006 example, and add more examples. Reported by Eric Sunshine.
6008 2004-01-05 Paul Eggert <eggert@twinsun.com>
6010 * doc/autoconf.texi (Limitations of Usual Tools):
6011 Remove warning against "rm -fr" introduced yesterday; it
6012 was a false alarm.
6014 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6015 autoscan, autoupdate, ifnames): Don't use chmod -w.
6016 * lib/Makefile.am (autom4te.cfg): Likewise.
6017 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6018 "chmod -w".

6021 Paolo Bonzini <bonzini@gnu.org>
6023 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
6024 by doing lineno substitution only on lines containing "$LINENO".
6026 2004-01-04 Paul Eggert <eggert@twinsun.com>
6028 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6029 Use "rm -f" to remove conftest.sed, not plain "rm".
6030 Bug reported by David Relson in
6031 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6033 * Makefile.am (autom4te-update):
6034 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6035 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6036 * doc/autoconf.texi (Guidelines): Likewise.
6037 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.

6041 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
6042 * tests/Makefile.am (clean-local): Likewise.
6043 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6044 srcdir): Likewise.
6045 * doc/autoconf.texi (Limitations of Usual Tools):
6046 Warn against "rm -fr".
6048 2004-01-03 Paul Eggert <eggert@twinsun.com>
6050 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6051 -c -o might not work. From a suggestion by Kevin Ryde.
6052 (C Compiler, Generating Sources, Limitations
6053 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6054 Don't put '-o' after non-options, as POSIX doesn't allow this.
6055 Mention that cc's name might be gcc or c89 or whatever.
6057 2004-01-04 Kevin Ryde <user42@zip.com.au>
6059 * doc/autoconf.texi: Add various further index entries.
6061 2003-12-29 Paul Eggert <eggert@twinsun.com>
6063 * bin/autoreconf.in (autoreconf_current_directory):
6064 Fix typo: mkdir without umask arg.
6066 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6068 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6069 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6070 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6071 explanation clearer.
6073 2003-12-24 Andreas Schwab <schwab@suse.de>
6075 * doc/autoconf.texi (Default Includes): Fix misspelling of
6076 AC_INCLUDES_DEFAULT.

6080 * configure.ac: Test if sh -n works.
6081 * configure: Regenerate.
6082 * tests/atlocal.in: Store the result here.
6083 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6084 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6085 of explicitly testing.
6086 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6087 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6088 * tests/tools.at (Syntax of the shell scripts): Simplify
6089 using AT_CHECK_SHELL_SYNTAX.

6103 Extracted from AS_SHELL_SANITIZE.
6104 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6105 macros.
6106 (AS_SHELL_SANITIZE): Move reinvocation code from
6107 _AS_LINENO_WORKS, use it to find out if shell
6108 functions work.
6109 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6110 does not work.
6111 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

6130 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6173 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6174 than $target since the latter is not usual, add guidelines on when to
6175 use or not use the system type.

6256 2003-10-28 Akim Demaille <akim@epita.fr>
6258 * Makefile.cfg (local_updates, executable-update): Tweak to be

6332 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
6334 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6335 cross test.
6337 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6339 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6340 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
6342 2003-10-10 Andreas Schwab <schwab@suse.de>
6344 * bin/autoheader.in: Avoid empty first line in --version and
6345 --help output.
6346 * bin/ifnames.in: Likewise.
6348 2003-10-09 Paul Eggert <eggert@twinsun.com>
6350 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
6351 Issue a more-informative diagnostic.
6352 Problems reported by Eric Sunshine.
6354 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6356 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6357 -mGLOB_options_string stuff for Intel ifc, which can cause
6358 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
6359 pattern-matching instead of grep.
6361 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6363 * doc/autoconf.texi: Document new FC Fortran macros.
6365 2003-10-08 Gary V. Vaughan <gary@gnu.org>
6367 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
6368 that future autopoint/aclocal/automake/autoreconf will be able
6369 to trace to find where to install local m4 macros.
6370 * doc/autoconf.texi (Input): Document it.
6371 * NEWS: Updated.
6373 2003-10-06 Gary V. Vaughan <gary@gnu.org>
6375 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
6376 -lcrtbegin.o to list of ignored flags and fix underquoting of
6377 -lcrt[01].o.
6379 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6381 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6382 cache variable instead of $G77 to decide whether to include -O2,
6383 since $G77 is specific to Fortran 77.
6385 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6387 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6388 free" flag. Re-order flags tested into rough order of popularity.
6390 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6392 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6393 arguments so that it can be used with syntax identical to
6394 AC_PROG_F77, and so that we can more easily decide to
6395 remove/deprecate the DIALECT optional argument in the future if it
6396 proves troublesome.
6397 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6398 non-freeform-supporting compilers. Document freeform flags.
6400 2003-10-03 Akim Demaille <akim@epita.fr>
6402 * configure.ac: Look for emacs, not macs.
6403 Reported by Eric Sunshine.
6405 2003-10-03 Akim Demaille <akim@epita.fr>
6407 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
6408 * bin/autoreconf.in (autoreconf_current_directory): Create the
6409 AUX_DIR if needed, for sake of automake --add-missing etc.
6410 Suggested by Alexandre Duret-Lutz.
6412 2003-10-03 Akim Demaille <akim@epita.fr>
6414 * configure.ac: Quotation and formatting changes.
6415 (EMACS): Don't set it if it is not recent enough to support
6416 autoconf-mode.el.
6417 From Eric Sunshine.
6419 2003-10-02 Akim Demaille <akim@epita.fr>
6421 * bin/ifnames.in (&scan_file): Skip C++ comments.

6427 Fix misspelling of HAVE_STRUCT_STAT_ST_BLOCKS.
6429 2003-10-01 Akim Demaille <akim@epita.fr>
6431 Version 2.57f.
6433 2003-09-30 Paul Eggert <eggert@twinsun.com>
6435 * lib/Autom4te/XFile.pm: Use Errno.
6436 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
6437 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
6439 2003-09-30 Akim Demaille <akim@epita.fr>
6441 * config/announce-gen (&print_news_deltas): Extracted from...
6442 (&print_changelog_deltas): here.
6443 (&news_file): Rename as...
6444 (@news_file): this.
6446 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
6448 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
6449 have been created when invoking the compiler.
6450 * tests/fortran.at (GNU Fortran 77): Quote $G77.
6452 2003-09-29 Akim Demaille <akim@epita.fr>
6454 Version 2.57e.
6456 * config/mkinstalldirs: Upgrade.
6458 2003-09-28 Paul Eggert <eggert@twinsun.com>
6460 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
6461 Problem reported by Lars J. Aas in
6462 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6463 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6464 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6465 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6467 2003-09-26 Akim Demaille <akim@epita.fr>
6469 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6470 directory for AC_CONFIG_COMMANDS' first argument exists.
6471 This makes valid the invocation of _AC_SRCPATH that follows.
6472 Reported by Eric Sunshine.
6473 * doc/autoconf.texi (Configuration Commands): Adjust.
6475 2003-09-26 Akim Demaille <akim@epita.fr>
6477 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6478 Reported by Ralf Corsepius.
6480 2003-09-26 Akim Demaille <akim@epita.fr>
6482 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6483 arguments.
6484 Actually, use AU_ALIAS.
6485 From Bruno Haible.
6487 2003-09-26 Paul Eggert <eggert@twinsun.com>
6489 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6490 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6491 Problem reported by Eric Sunshine in:
6492 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
6494 2003-09-26 Akim Demaille <akim@epita.fr>
6496 The test suite are sometimes assigning timings incorrectly.
6497 Reported by Henk Krus.
6498 Diagnosed by Nicolas Joly.
6500 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6501 AT_help_all.
6502 Instead of making AT_help a sequence of assignments to grow
6503 $at_help_all, just make AT_help_all be the growing contents of
6504 $at_help_all, and make a single assignment in...
6505 (AT_INIT): here.
6506 (at_times_skip): Flip the meaning and rename as...
6507 (at_times_p): this.
6508 (AT_INIT): When summarizing the test that ran, remove
6509 $at_times_file after use, and check it is present before trying to
6510 use it.
6512 2003-09-25 Akim Demaille <akim@epita.fr>
6514 Version 2.57d.
6516 * bin/Makefile.am (edit): Handle '@configure_input@'.
6517 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6518 (ifnames): chmod -w.
6519 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6520 executables, not bin/ executables! Otherwise all the magic needed
6521 to find non installed files is turned off. This caused a failure
6522 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6523 as found in its environment (sent by tests/autoreconf): pointing
6524 to bin/autom4te that could not find its files.
6525 * tests/mktests.sh: Force the replacement of generated files, for
6526 the sake of "mv" program that are interactive when overwriting a
6527 -w file.
6528 * config/install-sh: Upgrade from CVS Automake.
6530 2003-09-23 Paul Eggert <eggert@twinsun.com>
6532 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6533 versus test -L issues.
6535 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6536 Paul Eggert <eggert@twinsun.com>
6538 Trivial change to support GCC's configuration procedure.
6539 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6540 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6541 about inconsistency if the preprocessor is set to give errors for
6542 any warning.
6543 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6545 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6547 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6548 and XFile.pm from Automake.
6549 * lib/Autom4te/XFile.pm: Update from Automake.
6551 2003-09-12 Akim Demaille <akim@epita.fr>
6553 Version 2.57c.
6555 2003-09-12 Akim Demaille <akim@epita.fr>
6557 * config/config.guess, config/config.sub, config/missing,
6558 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
6559 from masters.
6561 2003-09-12 Akim Demaille <akim@epita.fr>
6563 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6564 not asm/types.h.
6566 2003-09-11 Akim Demaille <akim@epita.fr>
6568 * doc/autoconf.texi (Header Portability): linux/random.h.
6569 From Peter Hendrickson.
6571 2003-09-10 Akim Demaille <akim@epita.fr>
6573 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6574 willing to edit the output files.
6576 2003-09-10 Akim Demaille <akim@epita.fr>
6578 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6579 and AC_FC_FREEFORM.
6580 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6581 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6583 2003-09-09 Akim Demaille <akim@epita.fr>
6585 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
6586 Reported by Gary Vaughan.
6587 * bin/autom4te.in (handle_m4): Likewise.
6589 2003-09-09 Akim Demaille <akim@epita.fr>
6591 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
6592 trailing files.
6594 2003-09-07 Paul Eggert <eggert@twinsun.com>
6596 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6597 Improve the accuracy of the wording about obsolescence.
6598 From a suggestion by Ian Lance Taylor in
6599 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6601 2003-09-05 Paul Eggert <eggert@twinsun.com>
6603 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6604 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6606 2003-09-04 Akim Demaille <akim@epita.fr>
6608 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6609 AC_FUNC_WAIT3.
6611 2003-09-04 Akim Demaille <akim@epita.fr>
6613 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6614 (freeze): When exiting, use $exit_code.
6615 * lib/autoconf/fortran.m4: Comment changes.
6617 2003-09-04 Akim Demaille <akim@epita.fr>
6619 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6621 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6623 Add support for newer Fortran dialects. The F77 interface is
6624 unchanged, and continues to support Fortran 77. New FC macros
6625 correspond to all the old F77 macros, with output variables FC,
6626 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6627 available dialect, but older dialects can be specified. There are
6628 new macros AC_FC_SRCEXT to set the source extension, and
6629 AC_FC_FREEFORM to accept free-form source files.
6631 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6632 New macros.
6633 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6634 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
6635 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
6636 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),
6637 AC_LANG_PROGRAM(Fortran), AC_LANG_CALL(Fortran),
6638 AC_LANG_PREPROC(Fortran), AC_LANG_COMPILER(Fortran),
6639 _AC_FC_DIALECT_YEAR, _AC_F95_FC, _AC_F90_FC, _AC_F77_FC,

6643 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
6644 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
6645 AC_FC_SRCEXT, AC_FC_FREEFORM):
6646 New macros.
6647 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
6648 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6649 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6650 Rewrite in terms of the above.
6651 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6652 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
6653 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
6654 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
6656 2003-09-02 Paul Eggert <eggert@twinsun.com>
6658 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6659 Document problems with timestamp resolution that 'make', 'cp -p', and
6660 'touch -r' have.
6662 2003-08-27 Akim Demaille <akim@epita.fr>
6664 * tests/m4sugar.at (cross_warning): Make sure to enable the
6665 output, so that we can track spurious m4sugar output.
6666 * tests/local.at: Require 2.57.
6667 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6668 are defaulted by AT_CHECK anyway.
6669 Use AT_CHECK_AUTOM4TE.
6670 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6671 missing dnl.
6673 2003-08-27 Akim Demaille <akim@epita.fr>
6675 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6676 when -Wobsolete is set.
6677 Set it on by default.
6678 Suggested by Klee Dienes.
6680 2003-08-27 Akim Demaille <akim@epita.fr>
6682 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
6683 documentation.
6684 From Guido Draheim.
6686 2003-08-26 Akim Demaille <akim@epita.fr>
6688 * doc/autoconf.texi (Output): Make clear that one can run code
6689 after AC_OUTPUT.
6691 2003-08-25 Akim Demaille <akim@epita.fr>
6693 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
6694 CVS Bison.
6696 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
6698 * bin/autoreconf.in (parse_args): Do not pass --no-force to

6712 Version 2.57b.
6714 * Makefile.cfg (local-checks-to-skip): New.
6715 * Makefile.maint (local-check): Rename as...
6716 (local-checks-available): this.
6717 (local-check): New.
6719 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6720 * configure.ac: Require Automake 1.7.6.
6722 2003-08-22 Akim Demaille <akim@epita.fr>
6724 Output stack traces in warnings.
6726 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6727 Replace the former...
6728 (m4_warn): Pass the call stack to _m4_warn.
6729 * bin/autom4te.in: Adjust to output the call stack.
6730 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6732 2003-08-22 Akim Demaille <akim@epita.fr>
6734 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6735 * bin/autom4te.in: Adjust.
6737 2003-08-21 Akim Demaille <akim@epita.fr>
6739 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6740 (&verbose): Remove.
6741 (&getopt): Adjust the note and verb channels, depending upon
6742 --verbose.
6743 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6744 * bin/autoupdate.in: Adjust.
6745 Use &verb, not &verbose.
6747 2003-08-21 Akim Demaille <akim@epita.fr>
6749 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6750 &parse_WARNINGS.
6751 ($help): Use Autom4te::ChannelDefs::usage.
6752 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6753 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6755 2003-08-21 Akim Demaille <akim@epita.fr>
6757 First stab at preserving warnings between calls to autom4te,
6758 including when the cache is used.
6760 There are still several issues: (i) there are too many runs of m4
6761 (one for include, one for warnings, and some more), (ii) warnings
6762 spreading on several lines are not handled gracefully, (iii) the
6763 code meant to have the call stack display for errors does not work
6764 (its handling should move from m4 to autom4te).
6766 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6767 Use them.
6768 (@preselect): Add m4_warn.
6769 ($exit_status): Remove, use $exit_code.
6770 ($help): Use Autom4te::ChannelDefs::usage.
6771 (&handle_m4): No longer define the m4_warnings.
6772 At each run, extract and report the warnings.
6773 Always cache the result, including if the exit status is on
6774 failure, since if nothing changes, we should result in the same
6775 failure, hence we can use the cache.
6776 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6777 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6778 Remove.
6779 (m4_warn): Redefine as a do-nothing: it is its invocation that
6780 matters, as warnings are now reported via traces.
6781 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6782 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6783 the latter reveals calls to the former.
6785 Adjust the tests.
6787 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6789 2003-08-21 Akim Demaille <akim@epita.fr>
6791 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6792 Use them.
6794 2003-08-21 Akim Demaille <akim@epita.fr>
6796 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6797 forward order.
6798 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6799 (&parse_warnings): Accept a list of warning requests.
6800 (&usage): Return a string, not a side effect.
6801 (cross): New warning category.
6803 2003-08-21 Akim Demaille <akim@epita.fr>
6805 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6806 (&require_configure_ac): Accept an optional directory argument.
6807 ($configure_ac): Remove.

6824 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6825 (&xsystem, &contents): Remove, since they are exported by...
6826 * lib/Autom4te/FileUtils.pm: this.
6827 More perldoc.
6828 * lib/Autom4te/General.pm (&up_to_date_p): Move to...

6890 2003-08-13 Derek Price <derek@ximbiot.com>
6892 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6893 output.
6895 2003-08-12 Derek Price <derek@ximbiot.com>
6897 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
6898 (AT_CHECK_NOESCAPE): Move core functionality to...
6899 (_AT_CHECK): ...this new macro.
6901 2003-08-07 Derek Price <derek@ximbiot.com>
6903 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
6904 (AT_CHECK_NOESCAPE): ...to this new macro.
6906 2003-07-31 Paul Eggert <eggert@twinsun.com>
6908 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6909 in Bash 2.01. Problem reported by Brian Gough in
6910 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6912 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
6914 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
6915 -lcrt1.o, for OS X. (trivial change)
6917 2003-07-07 Paul Eggert <eggert@twinsun.com>
6919 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
6920 inside '#ifndef __cplusplus'. Problem reported by
6921 Bob Friesenhahn.
6923 2003-07-06 Bill Clarke <llib@computer.org>
6925 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6926 'long', not 'int', for benefit of Sun's recent C++ compilers
6927 (trivial change). See:
6928 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6929 (This really should be 'intptr_t', not 'long', but that would
6930 take more work.)
6932 2003-06-25 Akim Demaille <akim@epita.fr>
6934 * lib/Makefile.am (autom4te.cfg): Make it read only.
6935 Depend on Makefile since it contains substitutions.
6936 From Paolo Bonzini.

6941 2003-06-25 Akim Demaille <akim@epita.fr>

6944 From Gareth McCaughan.
6946 2003-06-23 Akim Demaille <akim@epita.fr>
6948 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6949 not all of them. This fixes 1. the fact that when testing
6950 Autoconf there are many many config.log, 2. the incorrect use of
6951 top_srcdir to find config.log.
6952 Don't mix the detailed output of failed test with the summary of
6953 failures. Rather, append detailed log afterwards.
6955 2003-06-23 Akim Demaille <akim@epita.fr>
6957 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6958 always run: output config.log on $at_group_log.
6960 2003-06-23 Akim Demaille <akim@epita.fr>
6962 * tests/torture.at (#define header templates): Don't use quotes in

6967 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6968 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
6969 * tests/atspecific.m4: Rename as...

6972 * tests/local.at: here.
6973 * tests/Makefile.am: Adjust.
6974 * doc/autoconf.texi (testsuite Scripts): Adjust.
6976 2003-06-21 Kevin Ryde <user42@zip.com.au>
6978 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6979 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6980 ensuring we add -std1 for full-ANSI.
6982 * doc/autoconf.texi (hdrindex): New macro.

6985 2003-06-20 Akim Demaille <akim@epita.fr>

6989 2003-06-20 Akim Demaille <akim@epita.fr>
6991 Version 2.57a.
6993 2003-06-20 Akim Demaille <akim@epita.fr>
6995 * bin/autom4te.in: Don't rely on $HOME being defined.
6996 Reported by Marc Espie as PR/233.
6998 2003-06-20 Akim Demaille <akim@epita.fr>
7000 * lib/autotest/general.m4: Use at_times_file only if used.
7001 From Nicolas Joly.

7005 * config/config.guess, config/config.sub, config/elisp-comp,
7006 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7007 Update from masters.
7009 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7011 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7012 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7013 (TEST_SCRIPT): New diversion.
7014 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7015 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7016 (AT_INIT): Support for expected failures.
7018 2003-06-02 Akim Demaille <akim@epita.fr>
7020 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7021 changes.
7022 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7023 Autoconf nor Automake.
7024 (&contents): New, from Automake.
7025 PODify.
7027 2003-05-28 Paul Eggert <eggert@twinsun.com>
7029 * NEWS, doc/autoconf.texi (Particular Functions),
7030 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7031 is the inverse of localtime.
7033 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7035 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7036 (handle_exec_errors): New function. Work around $! being
7037 altered by WEXITSTATUS.
7038 (xqx, xsystem): Use handle_exec_errors.
7040 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7042 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7043 Do not call `_exit()', simply modify `$?'.
7044 (xsystem): Reset $! before running system, and check it afterward.
7045 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7046 63 for version mismatches.
7048 2003-05-23 Akim Demaille <akim@epita.fr>
7050 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7051 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7052 the middle of a line).
7053 * lib/m4sugar/m4sugar.m4: Likewise.
7054 Remove useless spaces in comments.
7056 2003-05-23 Akim Demaille <akim@epita.fr>
7058 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7059 exit 63, so that we (or Automake's "missing") can tell the
7060 difference with a plain failure.
7061 * doc/autoconf.texi (Notices): Adjust.
7063 2003-05-23 Akim Demaille <akim@epita.fr>
7065 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7066 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7067 White spaces cleanup.
7069 2003-05-22 Jim Meyering <jim@meyering.net>
7070 Paul Eggert <eggert@twinsun.com>
7072 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7073 Remove `#include <stdlib.h>' from the list; we should never
7074 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7075 resulting namespace pollution would cause other tests to fail.
7076 Configure scripts run with some older versions of g++ and HP's
7077 aCC would fail due to such an #include. Problems reported by
7078 Matthew Mueller in <http://bugs.debian.org/120704> and by
7079 Keith Bostic in
7080 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7081 In the test, use the test declaration before including <stdlib.h>,
7082 as that's closer to how it'll be used.
7084 2003-05-23 Akim Demaille <akim@epita.fr>
7086 * doc/autoconf.texi (Header Portability): ucred.h.
7087 From Ian Redfern.
7089 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7091 Overhaul Autotest's logging: generate separate log files
7092 in testsuite.dir/NNN/testsuite.log, and append them to
7093 testsuite.log instead of re-running the test verbosely.
7095 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7096 file descriptor, write 0 to at_status_file instead of setting
7097 at_status=0, initialize some new variables (at_status_file,
7098 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7099 to rerun the tests, instead append the at_group_log to the
7100 at_suite_log when a test fails.
7101 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7102 with the AS_MESSAGE_LOG_FD redirected to stdout.
7103 (AT_CLEANUP): save the output status in $at_status_file
7104 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7105 its original place.
7106 (AT_CHECK): since tests are run with a redirected stdout,
7107 and used to be re-run in verbose mode, turn some $at_verbose
7108 into echo, and don't redirect the output of testing stdout
7109 and stderr.
7111 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7112 the name of the debugging directory and information about
7113 its contents.
7115 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7117 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7118 parameter.
7120 2003-05-22 Akim Demaille <akim@epita.fr>
7122 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

7124 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

7141 Suggested by Jim Meyering.
7143 2003-05-22 Akim Demaille <akim@epita.fr>
7145 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
7146 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
7147 Reported by Jim Meyering.
7149 2003-05-22 Akim Demaille <akim@epita.fr>
7151 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

7184 2003-05-17 Akim Demaille <akim@epita.fr>
7186 * lib/autoconf/functions.m4: Use the default includes so that
7187 memcmp be declared before being tested.
7188 Reported by Sander Niemeijer.
7189 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

7191 AC_INCLUDES_DEFAULT.
7193 2003-05-17 Akim Demaille <akim@epita.fr>
7195 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
7196 * doc/autoconf.texi (Obsolete Macros): Adjust.
7197 Reported by Werner LEMBERG and Debian Bug 190886.
7199 2003-05-16 Akim Demaille <akim@epita.fr>
7201 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
7202 user name space clashes.
7203 Reported by Bruno Haible.
7205 2003-05-16 Akim Demaille <akim@epita.fr>
7207 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7208 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
7209 them uniform, and more robust to Perl special characters.
7210 Reported by Martin Mokrejs.
7212 2003-05-14 Akim Demaille <akim@epita.fr>
7214 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
7216 2003-05-14 Akim Demaille <akim@epita.fr>
7218 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

7223 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
7224 message.
7225 From Matthias Andree.
7227 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
7229 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
7230 and truncate.
7232 2003-05-06 Akim Demaille <akim@epita.fr>
7234 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7235 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7236 by aclocal.m4 is changed it might require the importing of another
7237 m4 extension file, i.e., aclocal must be run.
7239 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7240 (&parse_args): Use --force with aclocal if required and supported.
7241 (&autoreconf_current_directory): Use &run_aclocal.
7243 2003-05-06 Akim Demaille <akim@epita.fr>
7245 Lock autom4te's cache.
7247 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7248 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7249 argument instead of a file name, so that the request file remains
7250 open during the whole autom4te run.
7251 ($icache_file): New.
7252 (&freeze): Lock the $icache_file.
7254 2003-04-29 Derek Price <derek@ximbiot.com>
7256 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7257 seperator with m4_append_uniq(). It doesn't work.
7258 (AT_CLEANUP): Add `;' to end of at_help_all.
7259 (AT_INIT): Allow --keywords to be specified more than once. When
7260 grepping $at_help_all for keywords, use the field and keyword
7261 seperators to ensure a complete keyword match. Alter at_prev handling
7262 to support the new --keywords behavior.
7264 2003-04-27 Karl Berry <karl@freefriends.org>
7266 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7267 align better with others. I also made some of the individual
7268 entries on one line, for brevity and to make it easier for me to
7269 sort my dir-example file in the Texinfo distribution :).
7271 2003-04-12 Jim Meyering <jim@meyering.net>
7273 * NEWS: Mention the new macro.
7274 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

7338 2003-03-28 Akim Demaille <akim@epita.fr>
7340 * tests/torture.at (Configuring subdirectories): Require aclocal

7364 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
7365 obsolete AC_HELP_STRING.
7366 (AC_HELP_STRING): AU_DEFUN to...
7367 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
7368 * tests/m4sh.at (AS_HELP_STRING): New test.
7370 * tests/acgeneral.at: Regenerated.
7372 2003-03-26 Derek Price <derek@ximbiot.com>
7374 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
7375 sense. Verbosify the diversion definitions comment.

7415 (Automake): Automake 1.5+ no longer requires special tools to be
7416 present on the developer's host.

7425 * bin/autoreconf.in (BEGIN): Likewise.
7426 * bin/autoscan.in (BEGIN): Likewise.
7427 * bin/autoupdate.in (BEGIN): Likewise.

7432 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7433 to cope with DOS-style absolute paths, when constructing
7434 ${ac_make}.
7436 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7437 When constructing paths with IFS=:, quote the path. If we're
7438 constructing a DOS-style absolute path, we don't want to split it
7439 on the colon.
7441 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7442 in description.
7444 2003-02-25 Pavel Roskin <proski@gnu.org>

7456 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7457 to fix a mismatch between example and discussion.
7459 2003-02-24 Kevin Ryde <user42@zip.com.au>
7461 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7462 format starting with "-".
7464 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7466 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7467 is not portable inside Makefile.
7469 2003-02-20 Akim Demaille <akim@epita.fr>
7471 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7472 compiler says yeah, but preproc says nope, compiler is right.
7473 Conversely, prompt the reader to send a bug report to the
7474 maintainers of the package, not of Autoconf.
7476 2003-02-20 Klee Dienes <kdienes@apple.com>
7478 * bin/autoreconf.in (autoreconf_current_directory): Properly
7479 handle an empty aclocal.m4.

7485 From Larry Jones.
7487 2002-12-23 Paul Eggert <eggert@twinsun.com>
7489 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7490 innocuous variant befor including <limits.h> or <assert.h>. This
7491 works around a bug reported by Albert Chin: HP-UX 11i
7492 (and earlier versions) have a <limits.h> that declares
7493 gettimeofday and many other functions.
7495 2002-12-03 Paul Eggert <eggert@twinsun.com>
7497 Version 2.57.
7499 * NEWS, configure.ac: Update version.
7501 * doc/fdl.texi: Upgrade to FDL version 1.2.
7503 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7504 nontrivially in main's body, so that f's external declaration is
7505 not optimized away in AIX. This should fix the bug reported by
7506 Martin Frydl in
7507 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7509 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7510 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7511 defined, to support freestanding compilers. This should fix the
7512 bug reported by Momchil Velkov in
7513 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7515 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7516 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

7521 * Makefile.maint (www-gnu): New macro.
7522 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7523 the location has moved.
7525 2002-12-02 Martin Frydl <martin@systinet.com>
7527 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7528 \(.*\) match is too long and there is something more to be checked.
7529 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7531 2002-11-15 Akim Demaille <akim@epita.fr>

7537 * config/move-if-change: Indenting changes.
7538 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7539 * configure.ac (AM_INIT_AUTOMAKE): here.
7540 Require 1.7.1.
7542 2002-11-14 Akim Demaille <akim@epita.fr>
7544 Version 2.55.
7546 * config/config.guess, config/config.sub, config/install-sh:
7547 Update from masters.
7549 2002-11-14 Akim Demaille <akim@epita.fr>
7551 * Makefile.maint: Sync with Bison, i.e.:
7552 (po-check): Scan .l and .y files instead of the
7553 .c and the .h files that they generate. This fixes the bug
7554 reported by Tim Van Holder in:
7555 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7556 Look for N_ as well as for _. Try to avoid matching #define for
7557 N_ and _.
7558 From Paul Eggert.
7560 2002-11-14 Akim Demaille <akim@epita.fr>
7562 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7563 From Paul Eggert and Albert Chin-A-Young.
7565 2002-11-14 Akim Demaille <akim@epita.fr>

7568 From Paul Eggert and Albert Chin-A-Young.
7570 2002-11-14 Kevin Ryde <user42@zip.com.au>
7572 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7573 than assigning in main, to avoid HP cc +O3 optimizing it away.
7575 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7577 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7578 option. Process --recheck after parsing all options. Pass -q
7579 option to configure on --recheck.
7580 (AC_OUTPUT): Pass -q from configure to config.status.
7581 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7582 arguments to record.
7583 * doc/autoconf.texi (config.status Invocation): Document
7584 config.status -q option.
7586 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

7589 Makefile.in if Makefile.am exists.

7591 output AC_CONFIG_FILES if no Makefiles were found.
7593 2002-11-07 Akim Demaille <akim@epita.fr>

7600 2002-11-06 Akim Demaille <akim@epita.fr>
7602 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7603 declaration in extern "C" too.

7606 2002-11-06 Akim Demaille <akim@epita.fr>
7608 * tests/torture.at (Configuring subdirectories): Don't use grep
7609 -w.
7610 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7611 Reported by Ezra Peisach.
7613 2002-11-05 Akim Demaille <akim@epita.fr>
7615 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7616 Remove.
7617 We _have_ to stop using the old compatibility scheme that tried to
7618 avoid useless backslashes because Libtool 1.4.3 contains a
7619 AC_DEFINE([error_t], [int],
7620 [Define to a type to use for \`error_t' if it is not
7621 otherwise available.])
7622 We _have_ to quote the single quote and backslashes with \. The
7623 old compatibility scheme saw that ` was backslashed, and therefore
7624 did not quote the single quote. Hence before this patch, Autoconf
7625 was not compatible with Libtool.
7627 2002-11-04 Paul Eggert <eggert@twinsun.com>
7629 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

7634 2002-11-04 Akim Demaille <akim@epita.fr>
7636 Version 2.54c.
7638 * Makefile.maint (update, cvs-update, po-update, do-po-update):
7639 New.
7640 * config/texinfo.tex: Update.
7642 2002-11-03 Akim Demaille <akim@epita.fr>
7644 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7645 from...
7646 (&autoreconf): here.
7647 ($help, $make, &parse_args, &autoreconf_current_directory):
7648 Support -m/--make.
7649 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7651 2002-10-31 Bruno Haible <bruno@clisp.org>
7653 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.

7664 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
7665 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
7667 2002-10-31 Akim Demaille <akim@epita.fr>
7669 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7670 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7671 Make variable, not a shell variable.
7672 Suggested by Bruno Haible.
7674 2002-10-31 Akim Demaille <akim@epita.fr>
7676 * bin/autom4te.in (load_configuration): Reject #args out of any
7677 language.
7679 2002-10-31 Akim Demaille <akim@epita.fr>
7681 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
7682 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
7683 (_AC_RUN_IFELSE): Use it.
7684 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
7685 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
7686 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
7687 inline it.

7693 Suggested by Tim van Holder.
7695 2002-10-29 Paul Eggert <eggert@twinsun.com>
7697 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
7698 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7699 Problem reported by Bruno Haible.
7701 2002-10-29 Akim Demaille <akim@epita.fr>
7703 * doc/autoconf.texi (Header Templates): Put also in words what the
7704 pictures says to assist free style readers.
7705 (Customizing autom4te): s/--cache=/--cache /.
7707 2002-10-29 Akim Demaille <akim@epita.fr>
7709 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
7710 sys/wait.h.
7711 sparc_address_test returns void.
7712 Use it with an argument, as prototyped.
7713 From Bruno Haible.
7715 2002-10-29 Akim Demaille <akim@epita.fr>
7717 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

7723 * tests/torture.at (Deep Package): New test.

7729 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
7730 * doc/autoconf.texi (Invoking autom4te): Rename as...
7731 (autom4te Invocation): this, for consistency with the other nodes.

7746 * configure.ac: Bump to 2.54c.

7957 2002-10-22 Akim Demaille <akim@epita.fr>

7963 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""

8016 Reported by Alexandre Duret-Lutz.
8018 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8019 to frozen files in @ARGV, as @ARGV must remain being a list of

8022 (&freeze): Use &error.
8023 (&up_to_date): If a file that was included according to the cache
8024 is no longer there, then the output is out dated.

8026 --force is given.
8027 * tests/tools.at (autom4te cache): New.

8036 that error messages can be easily located, and use GNU Make
8037 format, so that Emacs' compile mode understands us.
8038 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8039 if some file was changed instead of `print'.
8040 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8074 file name to enable parallel executions.
8075 From Sam Varshavchik.
8077 2002-10-08 Akim Demaille <akim@epita.fr>
8079 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8080 aclocal invocation, as Gettext macros might not be visible to
8081 aclocal.
8082 Instead of blindly running autopoint, scan configure.ac (not the
8083 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8084 Reported by Paul D. Smith.
8086 2002-10-08 Paul Eggert <eggert@twinsun.com>
8088 Work around problems found when POSIXLY_CORRECT=1 is set.
8089 None of this seems to have anything to do with POSIX, really,

8091 * bin/autom4te.in (parse_args): Configure GetOpt with
8092 "permute", too.
8093 * doc/autoconf.texi (Invoking autom4te):

8116 * tests/torture.at (Configuring subdirectories): Be robust to
8117 users who use config.site to require for a cache: in this case,
8118 the two last configure runs, using two different sets of
8119 arguments, trigger a legitimate error.
8121 2002-09-28 Akim Demaille <akim@epita.fr>

8156 tests/autom4te itself.
8157 * lib/autoscan/Makefile.am: Include freeze.mk.
8158 (autoscan.list): New target --this file is no longer a source.

8166 tracking changes in autoscan.list.
8167 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8169 2002-09-28 Akim Demaille <akim@epita.fr>

8185 2002-09-28 Akim Demaille <akim@epita.fr>
8187 From now on, autoscan files must always map a macro name to a

8190 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8191 all.
8192 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8193 explicit.
8195 2002-09-28 Akim Demaille <akim@epita.fr>
8197 * bin/autoscan.in (%c_keywords): Remove.

8285 2002-09-13 Akim Demaille <akim@epita.fr>
8287 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8288 (chdir_init) might hang when stat'ing mounted directories.
8289 Reported by Vance Shipley.
8291 2002-09-12 Akim Demaille <akim@epita.fr>
8293 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8294 the lists.
8296 2002-09-12 Akim Demaille <akim@epita.fr>
8298 * doc/autoconf.texi (Defining Symbols): Present two different
8299 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8300 difference between 1 argument calls, and 2-3 argument calls.
8302 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8304 * doc/autoconf.texi: Review grammar and punctuation.
8306 2002-09-11 Paul Eggert <eggert@twinsun.com>
8308 * doc/autoconf.texi: Fix minor formatting, spelling, and
8309 grammatical typos.
8310 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8311 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8312 is obsolescent.
8314 2002-09-11 Akim Demaille <akim@epita.fr>
8316 * doc/autoconf.texi (Questions): Rename as...
8317 (FAQ): this.
8318 (Defining Directories): New.
8320 2002-09-09 Akim Demaille <akim@epita.fr>
8322 * doc/autoconf.texi (Making testsuite Scripts): Update.
8323 Suggested by Nishio Futoshi.
8325 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8327 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8328 plain `@' is wanted.
8330 2002-09-09 Akim Demaille <akim@epita.fr>
8332 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8333 `duplicates', since the algorithm was too naive and could keep
8334 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8335 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8336 Reported by Ralf Corsepius.
8337 * tests/torture.at (Configuring subdirectories): Exercise these
8338 cases.
8340 2002-09-09 Akim Demaille <akim@epita.fr>
8342 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8343 looking for a replacement file.
8344 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8345 directory is relative.
8346 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8347 directory definition.
8348 Reported by Andreas Schwab and Jim Meyering.
8350 2002-09-06 Akim Demaille <akim@epita.fr>
8352 * doc/autoconf.texi (Setting Output Variables): Clarify what
8353 precious variables are.
8354 Suggested by Pontus Skoeld.
8356 2002-09-05 Akim Demaille <akim@epita.fr>
8358 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8359 (ifnames, autoscan, autom4te): Since we don't only depend on
8360 configure.ac variables (such as VERSION etc.), but also on prefix
8361 and so forth, depend on Makefile, not configure.ac.
8362 Reported by Alexandre Duret-Lutz.
8363 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8365 2002-09-05 Kevin Ryde <user42@zip.com.au>
8367 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8368 doesn't seem to be confined to ia64, just say "some versions".
8370 2002-09-04 Akim Demaille <akim@epita.fr>
8372 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8373 Automake 1.6c.
8374 * Makefile.am (maintainer-clean-local): Remove.
8375 (MAINTAINERCLEANFILES): Remove COPYING.
8377 2002-09-03 Paul Eggert <eggert@twinsun.com>
8379 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8380 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8381 Brinkmann.
8383 2002-09-03 Akim Demaille <akim@epita.fr>
8385 * configure.ac: Bump to 2.53d.
8386 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8387 as of today, on Automake's team suggestion.
8389 2002-09-03 Akim Demaille <akim@epita.fr>
8391 Version 2.53c.
8393 2002-09-02 Akim Demaille <akim@epita.fr>
8395 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8396 SITE_MACRO_DIR.
8397 * configure.ac: Disable SITE_MACRO_DIR.
8399 2002-09-02 Jim Meyering <meyering@lucent.com>
8401 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8402 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8403 Also, tweak grammar: s/make sure to/be sure to/.
8405 2002-09-02 Paul Eggert <eggert@twinsun.com>
8407 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8408 directory names are generally preferable to physical names.
8410 2002-09-02 Akim Demaille <akim@epita.fr>
8412 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8413 Reported by Raja R. Harinath.
8414 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8415 * bin/autoupdate.in: Use error instead of die.
8417 2002-09-01 Paul Eggert <eggert@twinsun.com>
8419 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8420 ordinary shell concatenation rather than echo+tr+sed command that
8421 runs afoul of a long-line-related sed bug in Solaris 8.
8423 * bin/autoheader.in (parse_args): --warning -> --warnings.
8425 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8426 stdout, as traditional "ls" does.
8427 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8428 _AC_COMPILER_EXEEXT_O): Likewise.
8429 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8431 * bin/autoconf.as: Add --prepend-include option. This patch was
8432 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8433 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8435 * bin/autoconf.in, configure: Regenerate.
8437 * doc/autoconf.texi (Special Shell Variables): Mention
8438 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8440 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8441 MAILPATH and set PS1, PS2, PS4 to default values, to work
8442 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8443 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8444 the Autoconf documentation specifies; fall back to "unset" only if
8445 this fails. Use a shell for-loop for this rather than an m4 loop,
8446 to shorten the output script.
8448 2002-08-30 Paul Eggert <eggert@twinsun.com>
8450 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8451 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8452 for the CDPATH problem. Document PWD.
8453 (Limitations of Builtins): Document the problem that "cd $foo" and
8454 "ls $foo" may refer to different directories in shells conforming
8455 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8456 example, since the old example is now out of date.
8458 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8459 FOO" and "ls FOO" talk about different directories; this catches
8460 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8461 spaghetti.
8463 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8464 of rolling our own unset.
8465 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8466 in practice we needn't worry about CDPATH if unset doesn't work.
8468 * Makefile.in, aclocal.m4, bin/Makefile.in,
8469 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8470 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8471 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8472 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8473 tests/Makefile.in: Regenerate with Automake 1.6.3.
8475 * config/config.guess, config/config.sub, config/mkinstalldirs:
8476 Update.
8478 * configure: Regenerate with self.
8480 2002-08-30 Kevin Ryde <user42@zip.com.au>
8482 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8483 default output.
8485 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8487 * bin/autom4te.in (Request::load): Correctly test for "do" read
8488 failure.
8490 2002-08-29 Akim Demaille <akim@epita.fr>
8492 * lib/Autom4te/General.pm (&xqx): New.
8493 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8494 hand, which is not portable.
8495 (&error): New.
8496 * bin/autom4te.in: Use them.
8497 Use &error instead of die.
8498 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8499 Adjust.
8501 2002-08-17 Paul Eggert <eggert@twinsun.com>
8503 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8504 default list of compilers to try, since it was long ago superseded
8505 by the ksh fc builtin. Suggested by Steven G. Johnson.
8507 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8509 * doc/autoconf.texi (Invoking autom4te): End the option table,
8510 fixing a bug introduced by the previous patch.
8511 (Limitations of Make): Add a 'target lookup' subentry in the
8512 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8514 2002-07-29 Mark D. Roth <roth@feep.net>
8516 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8517 options and use $AUTOM4TE_PATH.
8518 * doc/autoconf.texi: Remove documentation of autom4te
8519 --include-envvar and --site-macro-subdir options and document
8520 use of $AUTOM4TE_PATH.
8521 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8522 arguments from each language section.
8524 2002-07-29 Paul Eggert <eggert@twinsun.com>
8526 * doc/install.texi: Include copyright symbol in copyright notice.
8528 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8529 Replace with:
8530 (AM_MAKEINFOFLAGS): New macro.
8531 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8532 * Makefile.am (INSTALL): Use the new macros.
8533 Use -o rather than --output, since "missing" does not grok --output.
8535 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8537 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8538 comments do not always work. Never trust the exit status of
8539 `make -k'.
8541 2002-07-24 Kevin Ryde <user42@zip.com.au>
8543 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8544 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8546 2002-07-23 Paul Eggert <eggert@twinsun.com>
8548 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8549 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8550 apparently treats PATH="nonexistent" as if it contained ".".
8551 Bug reported by Stefan `Sec' Zehl.
8553 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8555 * doc/autoconf.texi (Limitations of Make): Mention the special
8556 handling of the obj/ directory by BSD make.
8558 2002-07-20 Kevin Ryde <user42@zip.com.au>

8561 backslashes.
8563 2002-07-19 Akim Demaille <akim@epita.fr>

8572 2002-07-18 Akim Demaille <akim@epita.fr>
8574 Version 2.53b.
8576 2002-07-18 Akim Demaille <akim@epita.fr>
8578 * config/config.guess, config/config.sub: Update.
8580 2002-07-18 Akim Demaille <akim@epita.fr>
8582 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and

8589 2002-07-18 Akim Demaille <akim@epita.fr>,
8590 Alexandre Duret-Lutz <duret_g@epita.fr>
8592 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8593 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

8598 description of the tarname default.

8602 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8603 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8604 latter was not run.
8606 2002-07-17 Akim Demaille <akim@epita.fr>
8608 * lib/Autom4te/General.pm (find_file): Browse the directories in
8609 the order they are given.

8629 macro directory, remove note that include path directories are
8630 used in reverse order, and document --prepend-include option.
8631 * lib/autom4te.in: Use --prepend-include instead of --include.
8632 * tests/wrapsh.in: Use --prepend-include instead of --include.
8634 2002-07-17 Akim Demaille <akim@epita.fr>

8689 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
8690 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
8691 so that we consistently test the just-built programs.
8692 * tests/wrappl.as: Likewise.
8694 2002-06-12 Paul Eggert <eggert@twinsun.com>
8696 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
8697 name, so that symlinks to 'autoconf' work properly. Bug reported
8698 by Bruno Haible.

8700 * bin/autoreconf.in (autoconf, autoheader): Likewise.
8701 * bin/autoscan.in (autom4te): Likewise.
8702 * bin/autoupdate.in (autom4te): Likewise.
8704 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
8705 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
8706 on Solaris 2.5.1.
8708 2002-06-11 Andreas Schwab <schwab@suse.de>
8710 * doc/autoconf.texi: Add more dir entries.
8712 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8714 * bin/autom4te.in ($cache): Don't define using `$me', the name
8715 of the cache should not depend on the name under which autom4te
8716 was installed.
8718 2002-06-07 Akim Demaille <akim@epita.fr>
8720 * tests/tools.at (autoconf: forbidden tokens, basic)
8721 (autoconf: forbidden tokens, exceptions): Adjust to the change of
8722 words in autom4te.in.
8724 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8726 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8727 _AC_LANG_PROGRAM_C_F77_HOOKS.
8729 2002-06-07 Akim Demaille <akim@epita.fr>

8774 * config/config.guess, config/config.sub, config/texinfo.tex:
8775 Update from masters.
8777 2002-05-29 Paul Eggert <eggert@twinsun.com>
8779 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
8780 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
8781 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
8782 Likewise.
8783 * lib/autoconf/Makefile.am (check-local): Likewise.
8784 * lib/autoconf/status.m4 (AC_CONFIG_HEADER): Likewise.
8785 * lib/autoconf/types.m4 (commentary only): Likewise.

8789 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
8790 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
8792 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
8793 * doc/autoconf.texi (Particular Programs): Document them.
8794 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
8795 * NEWS: Likewise.
8797 2002-05-27 Paul Eggert <eggert@twinsun.com>
8799 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
8800 * NEWS, doc/autoconf.texi (Particular Types): Document it.
8801 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
8802 instead of AC_MBSTATE_T, which never existed.
8804 2002-05-23 Akim Demaille <akim@epita.fr>
8806 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
8807 version of Autoconf that is discussed.
8809 2002-05-22 Paul Eggert <eggert@twinsun.com>
8811 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8812 from the default list of compilers to try. Suggested by
8813 Kate Hedstrom.
8814 * NEWS: Document the above.
8815 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8817 2002-05-17 Paul Eggert <eggert@twinsun.com>
8819 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8820 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8821 This improves on an earlier suggestion by H. Peter Anvin.
8823 2002-05-16 Paul Eggert <eggert@twinsun.com>
8825 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8826 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8827 Both macros now accept an optional source-dir arg.
8828 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8830 * NEWS: Document this.
8831 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8833 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8834 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8835 not for GNU extensions; this undoes part of the 2000-11-03 change,
8836 reverting to 2.13-compatible behavior.
8837 Add new optional argument DIR.
8838 (AC_FUNC_FNMATCH_GNU): New macro.
8840 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8842 2002-05-08 Paul Eggert <eggert@twinsun.com>
8844 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8845 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8846 and it causes a 'test' syntax error if it fails.
8847 Bug reported by Stephen Gildea.
8849 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8850 If prototypes are supported, use them to check this at compile-time,
8851 instead of trying to check it at run-time. If we must do a run-time
8852 check, assume that setvbuf is standard when cross-compiling, as
8853 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8854 Bug reported by Paul D. Smith.
8856 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8857 argument specifying location of getloadavg.c. This removes a
8858 FIXME. This idea was taken from Jim Meyering's implementation in
8859 textutils.
8860 * doc/autoconf.texi (Particular Functions): Document this.
8861 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8862 that's what the code does; this fixes a bug reported by
8863 Paul D. Smith.
8865 2002-05-03 Akim Demaille <akim@epita.fr>
8867 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8868 autopoint instead of gettextize.
8869 ($uses_alocal): Rename as...
8870 ($uses_aclocal): this.
8871 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8872 Suggested by Bruno Haible.
8874 2002-05-03 Akim Demaille <akim@epita.fr>
8876 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8878 2002-04-29 Paul Eggert <eggert@twinsun.com>
8880 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8881 files to be 1 second older; just set them to be the same time.
8882 Also, sleep 1 second after the first aclocal, to work around
8883 problems with sub-second time stamps on the input files.
8885 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8887 * doc/autoconf.texi: Mention "set -e -x" lossage
8888 under node "Limitations of Builtins".
8890 2002-04-29 Akim Demaille <akim@epita.fr>
8892 * doc/install.texi: Better wording for setting variables when
8893 running configure.
8894 From Christian Cornelssen.
8896 2002-04-29 Akim Demaille <akim@epita.fr>
8898 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8899 of lack of $LINENO support, then the test will compare the $LINENO
8900 in testsuite vs. the lineno in the test file. This is wrong, of
8901 course.
8902 Be sure to protect it.
8903 Reported by Patrick Welche.
8905 2002-04-25 Akim Demaille <akim@epita.fr>
8907 * doc/autoconf.texi (Obsolete Macros): Typo.
8908 Reported by Vladimir Volovich.
8910 2002-04-25 Akim Demaille <akim@epita.fr>
8912 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8913 than some of the input files, hence, on the second run of aclocal,
8914 if some of its input are younger, make them older.
8915 Suggested by Paul Eggert.
8917 2002-04-25 Akim Demaille <akim@epita.fr>
8919 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8920 Thanks to Paul Eggert.
8922 2002-04-25 Akim Demaille <akim@epita.fr>
8924 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8925 and ac_subst_vars be sh variables containing the list of
8926 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8927 DEFAULT diversion.
8928 (_AC_INIT_PREPARE): Use them to log them.
8929 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8930 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8931 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8932 _AC_SUBST_FILES and _AC_SUBST_VARS.
8933 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8935 2002-04-24 Akim Demaille <akim@epita.fr>
8937 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8938 autoheader, so that automake does not complain about a missing
8939 config.h.in that was to be created.
8941 2002-04-23 Akim Demaille <akim@epita.fr>
8943 * bin/autoheader.in (parse_args): --warning takes an argument.
8944 Fixes PR/220.
8946 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8948 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
8949 and bb.out when cleaning up.
8951 2002-04-22 Akim Demaille <akim@epita.fr>
8953 Version 2.53a.
8955 2002-04-22 Akim Demaille <akim@epita.fr>
8957 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
8959 2002-04-22 Akim Demaille <akim@epita.fr>
8961 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
8962 comma.
8963 Reported by Gregory Giannoni.
8965 2002-04-22 Akim Demaille <akim@epita.fr>
8967 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
8968 Fixes false failures on Darwin.
8970 2002-04-21 Paul Eggert <eggert@twinsun.com>

8974 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

8993 Minor spelling and grammar fixes.
8995 * doc/autoconf.texi: Follow the outline suggested in the GNU
8996 Sample Texts sections of the Texinfo 4.2 manual. Most
8997 importantly, this makes sure that the copyright notices appear in
8998 all output formats. You probably need Texinfo 4.2 to generate
8999 the manual now.
9001 Fix some bugs when using "$@" when there might be zero positional
9002 arguments in cases where this matters.

9022 * tests/c.at: We can't have zero arguments, so remove workaround
9023 that is not portable to Zsh.
9025 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9027 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9028 from aclocal.m4 too.
9030 2002-04-12 Akim Demaille <akim@epita.fr>
9032 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9034 2002-04-10 Akim Demaille <akim@epita.fr>
9036 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9037 workaround for ${1+"$@"}.
9038 * doc/autoconf.texi (Shell Substitutions): Explain it.
9039 From Oliver Kiddle and Peter Stephenson.
9041 Have M4sh perform minimal shell sanitizing.
9043 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9044 part into...
9045 (_AS_PREPARE): this new macro.
9046 (AS_PREPARE): New.
9047 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9048 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9050 Adjust Autoconf and Autotest.
9052 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9053 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9054 * lib/autotest/general.m4 (AT_INIT): Likewise.
9055 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9056 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9057 AS_SHELL_SANITIZE.
9059 Use this M4sh to generate Autoconf's shell scripts.
9061 * tests/wrapsh.as: New, precursor of wrapsh.in.
9062 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9063 on Autotest and M4sh.
9064 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9065 (wrapsh.in): New target.
9066 * bin/autoconf.as: New, precursor of autoconf.in.
9067 (autoconf.in): New target.

9072 with indented comments in rules.
9074 2002-04-09 Andreas Schwab <schwab@suse.de>
9076 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9077 ac_top_builddir when setting ac_abs_top_builddir.
9079 2002-04-06 Kevin Ryde <user42@zip.com.au>
9081 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9082 (Portable Shell): Cross reference to Systemology.
9084 2002-04-05 Akim Demaille <akim@epita.fr>
9086 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9087 directories when descending in a SUBDIRS.
9088 Reported by Ezra Peisach.
9090 2002-04-04 Andreas Schwab <schwab@suse.de>
9092 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9093 contains no literal separators.
9095 2002-04-03 Akim Demaille <akim@epita.fr>
9097 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9098 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9099 Use dnl, not the KILL diversion.
9100 Extracted from...
9101 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9102 (AC_CONFIG_LINKS): here.
9103 Adjust.
9104 Don't use the KILL diversion, as it kills spurious output, which
9105 results in failures being hidden.
9106 Use m4_defn where appropriate.
9107 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9108 after the second argument.
9109 Use m4_defn.
9110 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9111 syntax, as it is provided by M4sugar.
9112 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9114 2002-04-03 Andreas Schwab <schwab@suse.de>
9116 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9117 expanded if $# <= 2.

9120 aclocal.

9127 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9128 (_AC_COMPILER_OBJEXT): Use them.
9129 Fixes Debian #138666.
9131 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9133 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

9136 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9137 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9138 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9139 (AC_C_CONST): Same.

9151 2002-03-28 Kevin Ryde <user42@zip.com.au>
9153 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9154 to avoid versions of HP C which don't allow that.
9156 2002-03-27 Paul Eggert <eggert@twinsun.com>
9158 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

9170 2002-03-25 Paul Eggert <eggert@twinsun.com>
9172 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9173 as POSIX requires, as it doesn't work with Zsh.
9174 * doc/autoconf.texi (Assignments): Document the problem.
9176 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9178 * doc/autoconf.texi (Limitations of Make): Mention more issue
9179 about VPATH, overriding of macros in sub-makes, and handling of
9180 SHELL.
9182 2002-03-21 Paul Eggert <eggert@twinsun.com>
9184 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9185 problem with here-document buffer boundaries.
9187 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9188 when reinvoking the shell, to work around problems with installers
9189 who put strange things like "cd" commands in their environments.
9191 2002-03-19 Akim Demaille <akim@epita.fr>

9194 From Aaron Ucko.

9205 From Nishio Futoshi.
9207 2002-03-19 Akim Demaille <akim@epita.fr>
9209 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9211 2002-03-18 Paul Eggert <eggert@twinsun.com>
9213 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9214 (Limitations of Usual Tools): Add mkdir section.
9216 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9217 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9218 back on AS_DIRNAME to compute prefixes otherwise; this is
9219 roughly what mkinstalldirs does. That way, we need not have
9220 our own filename disassembler. The old disassembler did not
9221 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9223 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9224 Create at_test_all by a series of assignments,
9225 not by a single assignment of a long string. The latter causes ksh
9226 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9227 presumably because of a buffer overrun.
9229 2002-03-14 Paul Eggert <eggert@twinsun.com>
9231 * lib/autotest/general.m4 (at_times_skip):
9232 Renamed from at_times. Now a boolean.
9233 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9234 says 'times: not found'.
9236 2002-03-14 Akim Demaille <akim@epita.fr>
9238 * bin/autoreconf.in (&study_gettextize): New.
9239 (&autoreconf): Handle newest gettextize.

9252 2002-03-13 Akim Demaille <akim@epita.fr>
9254 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9255 -p'.
9256 From Bob Proulx.

9270 Version 2.53.
9272 2002-03-08 Akim Demaille <akim@epita.fr>

9281 2002-03-08 Akim Demaille <akim@epita.fr>
9283 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9284 aliases the actual variables, and modifications of the former
9285 affect the latter.
9287 2002-03-08 Akim Demaille <akim@epita.fr>
9289 * bin/autom4te.in (&handle_m4): Protect us from corrupted file

9320 parallel builds.
9322 2002-03-04 Akim Demaille <akim@epita.fr>
9324 * doc/autoconf.texi (Transforming Names): Equality between target
9325 and host is irrelevant.
9326 (Specifying Names, Canonicalizing): Remove all references to the
9327 backward compatibility hooks. Rather, collect them all into...
9328 (Hosts and Cross-Compilation): this new section.
9329 * doc/install.texi (System Type): Ditto.
9330 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9331 that `--host' implies cross-compilation.
9333 2002-03-04 Akim Demaille <akim@epita.fr>
9335 * doc/autoconf.texi (Evaluation Macros): New.
9336 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9337 useless.
9338 (_m4_foreach): Define the variant with immediate evaluation so
9339 that it contains exactly the items, not an expression which
9340 evaluation is the current item.
9341 (m4_re_string, m4_re_word): Don't over quote them.
9343 2002-03-04 Akim Demaille <akim@epita.fr>
9345 Instead of having stacking `shift's evaluated at the end, let
9346 `foreach' loops immediately evaluate them.
9348 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9349 $*. This is the n-th time I change my mind, but hopefully this is
9350 the last...
9351 (m4_lquote): New.
9352 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9353 efficient.
9354 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9355 it was only a hack for m4_text_wrap.
9356 (m4_car2): Remove, replaced by...
9357 (m4_cdr): New.
9358 (_m4_foreach): Adjust.
9359 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9360 m4_bpatsubst for clarification.
9362 2002-03-04 Akim Demaille <akim@epita.fr>

9390 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9391 From Akinori Musha.

9433 sure not to introduce newlines in at_groups.

9438 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9439 is not available.

9446 not unsigned long.
9447 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9448 cross-compilers, too. This undoes some of the most recent change
9449 to this file.
9451 2002-02-05 Akim Demaille <akim@epita.fr>
9453 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

9470 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9471 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9473 2002-02-05 Akim Demaille <akim@epita.fr>
9475 * bin/autom4te.in (&parse_args): Implement `frozen files are
9476 optional are the sum of the previous files on the command line'.
9477 Also, pass `--reload-state=' on them, so...
9478 (handle_m4): don't.
9479 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9480 (M4sh): Rely on M4sugar.
9481 (Autotest, M4sh, M4sugar): Use frozen files.
9483 2002-01-31 Akim Demaille <akim@epita.fr>

9490 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9491 alphanumeric to `-' instead of `_'.
9493 2002-01-30 Akim Demaille <akim@epita.fr>
9495 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9496 for plain code, the other for cross-compilation code. The latter
9497 is now run with GCC only.

9509 * tests/torture.at (Configuring subdirectories): Use configure.in,
9510 so that aclocal 1.4 works.
9511 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9513 2002-01-28 Akim Demaille <akim@epita.fr>
9515 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9516 needs an argument.
9518 2002-01-28 Akim Demaille <akim@epita.fr>
9520 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9521 AUTOTEST_PATH *after* it was set.
9522 Don't put `.' in the PATH: the user should be precise and `./' if
9523 needed. In addition, given that the test suite does some `cd', if
9524 `.' is in the path, the `tested programs' sections will report
9525 programs found in the test suite's directory, while during the
9526 tests (performed in their own directory), these programs are no
9527 longer visible. In other words, the results is confusing and
9528 useless.
9529 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9531 2002-01-24 Akim Demaille <akim@epita.fr>

9543 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9544 Bourne. Use /bin/sh.
9545 From Andreas Buening.
9547 2002-01-24 Akim Demaille <akim@epita.fr>
9549 * config/config.guess, config/config.sub, config/texinfo.tex:

9571 2002-01-21 Akim Demaille <akim@epita.fr>
9573 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9574 message on invalid options.
9575 * bin/autom4te.in (parse_args): Don't use
9576 Autoconf::General::getopt with non valid options.
9578 2002-01-17 Jim Meyering <meyering@lucent.com>
9580 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9581 $ac_cv_exeext so we don't use an old, invalid, cached value.
9583 2002-01-11 Akim Demaille <akim@epita.fr>
9585 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9586 Meyering.

9588 limitation.

9595 package.m4, since is really depends upon configure.ac, not
9596 configure.
9597 * doc/autoconf.texi (testsuite Scripts): Adjust.
9598 * tests/Makefile.am (package.m4): New.
9599 EXTRA_DIST it since its a source.
9601 2002-01-06 Akim Demaille <akim@epita.fr>
9603 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9604 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9605 and PACKAGE_BUGREPORT from here...
9606 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9607 arguments.
9608 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9609 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9610 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9611 * tests/tools.at (autoheader): Adjust.
9612 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9614 2002-01-06 Akim Demaille <akim@epita.fr>

9633 2001-12-14 Akim Demaille <akim@epita.fr>
9635 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9636 trailing files, don't apply `-rf' to files which might not be
9637 created by configure (core, core.*, and *.core), but just `rm -f'.
9638 Suggested by Jonathan Kamens.
9640 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9642 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

9646 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9648 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

9676 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9677 Remove $filepath, useless.
9678 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9679 variables, they are really part of the tokens.
9680 Split the input line on spaces and then look for tokens.
9681 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9682 because of `lex$U.$(OBJEXT)'.
9683 (&scan_files): Use "@list" instead of join.
9684 * doc/Makefile.am (CLEANFILES): Add *.fns.
9686 2001-11-26 Akim Demaille <akim@epita.fr>

9751 This patch implements a `long double' suggestion by Oliver Kiddle.
9753 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9754 static, to catch errors if the value isn't known at compile-time
9755 and the compiler supports dynamic arrays. Change its name from
9756 `_array_' to `test_array' to avoid potential name clashes.
9757 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9758 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9759 better than double. Catch a bug in GCC 2.95.2 x86.
9760 * doc/autoconf.texi (C Compiler): Document the above.

9767 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9769 2001-11-13 Akim Demaille <akim@epita.fr>
9771 * lib/autotest/general.m4 (AT_INIT): After having run the test
9772 group, go back to the initial directory, not to at_suite_dir.
9774 2001-11-13 Akim Demaille <akim@epita.fr>
9776 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9777 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9778 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9779 option.
9780 (AT_CHECK_CONFIGURE): Use absolute paths.
9781 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9782 The problem is still the old one: there is no means in M4 (that I
9783 know about) to create a defining macro, because there is no means
9784 to create `$1' etc., therefore, the defining macro ``swallows''
9785 all the arguments meant to the defined macro.
9787 2001-11-13 Akim Demaille <akim@epita.fr>
9789 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9790 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9791 configure.ac.
9792 * tests/aclocal.m4: Remove, as it is no longer used.
9794 2001-11-13 Akim Demaille <akim@epita.fr>
9796 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9797 variable names when referring to a single test group, or to
9798 `suite' when referring to the whole test suite.
9799 `at_last_test' is removed: m4 compute at_format itself.
9800 (at_stdout, at_stder1, at_stderr): New variables.
9801 (AT_CHECK): Use them.
9803 2001-11-13 Akim Demaille <akim@epita.fr>
9805 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9806 in PATH.
9807 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9808 Do it as soon as a test fails, don't wait till the end of the test
9809 suite.
9810 Don't remove $as_me.[0-9]*, since these files no longer exist.
9812 2001-11-13 Akim Demaille <akim@epita.fr>
9814 * tests/tools.at: Use absolute paths, since we are no longer run
9815 in place.
9817 2001-11-13 Akim Demaille <akim@epita.fr>
9819 Now that tests are running in their own private dir, there is no
9820 need to list the files to remove at the end of tests groups.
9822 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9823 (AT_data_files, at_data_files): Remove.
9824 (AT_CLEANUP, AT_DATA): Simplify.
9825 (AT_INIT): Adjust.
9826 Remove the group dir if !debug && !failed.
9827 * tests/atspecific.m4: Adjust.
9829 2001-11-13 Akim Demaille <akim@epita.fr>
9831 Start a new layout for Autotest: `testsuite' creates
9832 `testsuite.dir' in which the at-check-line etc. files are to be
9833 found, and `testsuite.dir/003' where the test group 3 is run.
9835 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9836 at_check_line_file, at_format, at_test_normalized, at_group_dir
9837 are new variables.
9838 Create the directories.
9839 Use absolute paths for at- files.
9840 (AT_CHECK): Adjust.
9842 2001-11-11 Michael Matz <matz@kde.org>
9844 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9845 (m4_car2): New.
9846 (m4_car): Properly quote arguments.
9848 2001-11-13 Akim Demaille <akim@epita.fr>
9850 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9851 with stricter rules on LIBOBJS.
9853 2001-11-12 Paul Eggert <eggert@twinsun.com>
9855 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9856 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9857 __PROTOTYPES too.
9859 2001-11-12 Akim Demaille <akim@epita.fr>
9861 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9863 2001-11-12 Akim Demaille <akim@epita.fr>
9865 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9866 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9867 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9868 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9869 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9870 specify to what the macro should be defined (typically to 1).
9872 2001-11-12 Akim Demaille <akim@epita.fr>
9874 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9875 From Jim Meyering.
9877 2001-11-12 Akim Demaille <akim@epita.fr>
9879 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9880 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9881 definition used by Automake where LEX is +/- "${missing} lex" and
9882 `missing' itself contains variables.
9884 2001-11-12 Akim Demaille <akim@epita.fr>
9886 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9887 Now that M4sh pushes BODY, the comments were output at the end of
9888 the test suites.
9890 2001-11-08 Akim Demaille <akim@epita.fr>
9892 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9893 that we can trace macros from aclocal.m4.
9894 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9895 obsoleted, and redirect to the former anyway.
9896 Reported by Ralf Corsepius.
9898 2001-11-08 Akim Demaille <akim@epita.fr>
9900 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9901 processed only if present.
9902 * tests/torture.at (Configuring subdirectories): Use autoreconf
9903 instead of successive calls to autoconf.
9904 Add a nonexistent subdirectory to exercise the patch above.
9905 Reported by Ralf Corsepius.
9907 2001-11-08 Kevin Ryde <user42@zip.com.au>
9909 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9910 doesn't accept .S files.
9912 2001-11-07 Akim Demaille <akim@epita.fr>
9914 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9915 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9916 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9917 * bin/autom4te.in (warn_forbidden): New.
9918 (handle_output): Use it.
9919 Read m4_pattern_forbid with messages.
9921 2001-11-05 Akim Demaille <akim@epita.fr>
9923 * bin/autom4te.in (--normalize): Remove.
9924 * lib/autom4te.in: Adjust.
9926 2001-11-05 Akim Demaille <akim@epita.fr>
9928 * tests/Makefile.am (testsuite): Rename this target as...
9929 ($(TESTSUITE)): this.
9930 From Nicolas Joly.
9932 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9934 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9935 the --prefix option, also remove it's argument.
9937 2001-11-05 Akim Demaille <akim@epita.fr>
9939 * doc/autoconf.texi (testsuite Invocation): Update.
9940 (Writing testsuite.at): Update.
9942 2001-11-03 Akim Demaille <akim@epita.fr>
9944 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9946 2001-11-03 Akim Demaille <akim@epita.fr>
9948 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9949 (&file_name_is_absolute): New, wrappers around routines from
9950 File::Spec.
9951 Use and export them.
9952 (&find_configure_ac): Optionally take a directory where to look at.
9953 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9954 the arguments.
9955 Default @ARGV to `.', not find_configure_ac.
9956 (&autoreconf): Argument is a directory.
9957 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9958 * doc/autoconf.texi (autoreconf Invocation): Update.
9960 2001-11-03 Akim Demaille <akim@epita.fr>
9962 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9963 (@export_forward_subs): New.
9964 Add basename, dirname, and fileparse.
9965 (@EXPORT): Adjust.
9966 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9967 Don't look for aclocal flags if we already know aclocal is not
9968 used.
9969 Move aclocal.m4t only if it exists.
9970 Reported by Ezra Peisach.
9972 2001-11-03 Akim Demaille <akim@epita.fr>
9974 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9975 passed on command line, defaulting to ./configure.ac if present.
9976 (&maybe_autoreconf, File::Find): Remove, unused.
9977 (&autoreconf): If autoconf is not used, don't try to trace.
9979 2001-11-02 Akim Demaille <akim@epita.fr>
9981 * configure.ac: Bump to 2.52g.
9983 2001-11-02 Akim Demaille <akim@epita.fr>
9985 Version 2.52f.
9987 2001-11-02 Akim Demaille <akim@epita.fr>
9989 * config/config.guess, config/config.sub, doc/standards.texi:
9990 * config/lispdir.m4: Update from masters.
9991 * configure.ac: Bump to 2.52f.
9993 2001-11-02 Akim Demaille <akim@epita.fr>
9995 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9996 Don't run aclocal when aclocal.m4 is not from aclocal.
9997 From Ezra Peisach.
9998 Don't run libtoolize and gettextize if --install is not given.
10000 2001-11-01 Paul Eggert <eggert@twinsun.com>
10002 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10003 be invoked before _AS_LINENO_PREPARE.
10004 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10005 than character ranges.
10007 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10008 invoking AS_BASENAME. Set the locale variables to 'C' if
10009 possible, as POSIX requires this to get the traditional
10010 behavior.
10011 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10013 2001-10-31 Paul Eggert <eggert@twinsun.com>
10015 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10016 with {}, as that triggers a bug in Bash 2.05.
10018 (_AS_LINENO_PREPARE): Use Sed rather than
10019 Awk. Fix the sed prepass to work even if there are multiple
10020 instances of $LINENO on the same line. Do not substitute for
10021 other variables like $LINENOT. Do not check file dates; such a
10022 check is unreliable on sufficiently fast machines, and removing
10023 the check makes the code simpler and more reliable. Check for
10024 output and chmod failures.
10026 * doc/autoconf.texi (Special Shell Variables): Document
10027 the above.
10029 2001-10-31 Akim Demaille <akim@epita.fr>
10031 * tests/Makefile.am (atconfig): Remove this target, Automake
10032 handles it now.
10034 2001-10-31 Akim Demaille <akim@epita.fr>
10036 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10037 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10038 provided, while it is optional.
10039 * configure.ac: Adjust.
10041 2001-10-26 Paul Eggert <eggert@twinsun.com>
10043 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10044 lib/Autom4te/Struct.pm:
10045 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10046 with 5.005_02.
10048 * doc/autoconf.texi (Special Shell Variables): Document some
10049 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10051 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10052 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10053 eval $LINENO is not portable in practice.
10055 2001-10-24 Akim Demaille <akim@epita.fr>
10057 * lib/Autom4te/General.pm (backname): New.
10059 2001-10-24 Akim Demaille <akim@epita.fr>
10061 * m4/: Remove, merged into...
10062 * config/: here.
10064 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10066 * doc/autoconf.texi (Shellology): Mention the problems with bash
10067 2.05's use of ANSI quoting in its `set' builtin.
10069 2001-10-22 Paul Eggert <eggert@twinsun.com>
10071 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10072 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10073 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10074 POSIX decided to standardize on the int flavor of strerror_r.
10075 Always do char* test, as there's no reason not to.
10076 Assign to a char* var, to catch strerror_r that returns int*.
10078 * doc/autoconf.texi (Particular Functions):
10079 Document the above changes. Also, document the fact that
10080 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10082 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10084 2001-10-20 Akim Demaille <akim@epita.fr>
10086 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10087 the executable was missing from the log.

10091 * lib/Autom4te/General.pm (&update_file): If destination is
10092 unchanged, remove the source.
10093 (&up_to_date_p): Don't be verbose, be debug.
10094 * bin/autoreconf.in: No longer support --m4dir.
10095 (&autoreconf): Display the full path of the configure.ac we are
10096 studying.
10097 Trace it only once.
10098 Be sure to honor --force with gettextize.
10099 Always run aclocal.
10100 * doc/autoconf.texi: Adjust.
10102 2001-10-20 Akim Demaille <akim@epita.fr>
10104 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10105 Remove, dead.
10106 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10107 `intl' is already present, as it refuses unless --force.
10108 (&parse_args): Use -I, --include instead of the old Autoconf
10109 options.
10110 ($localdir, $autoconf_dir): Remove.
10111 (@include): New.
10112 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10114 2001-10-19 Jens Petersen <petersen@redhat.com>
10116 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

10121 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
10122 file in @configure_input@.
10123 Don't mention `automatically' in addition to `generated'.
10124 * tests/torture.at (#define header templates): Adjust.
10126 2001-10-19 Akim Demaille <akim@epita.fr>
10128 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10129 comment, explain how to install automatic mode selection.
10130 From Russ Allbery.
10132 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10134 * bin/autoreconf.in (autoreconf): Display the path to the
10135 configure.ac being studied.
10137 2001-10-18 Paul Eggert <eggert@twinsun.com>
10139 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10140 long, to work around a bug in the HP C compiler version HP92453-01
10141 B.11.11.23709.GP.
10143 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10144 (AS_BASENAME_EXPR): New macro.
10145 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10146 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10147 and fall back on 'sed' only if the other two fail. This makes
10148 AS_BASENAME act more like AS_DIRNAME.
10149 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10150 contains white space.
10151 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10152 Use AS_DIRNAME, since I think it's now DOS-friendly.
10153 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10154 Allow "dirname //FOO" to return either / or //, as POSIX allows
10155 either behavior.
10157 2001-10-10 Akim Demaille <akim@epita.fr>
10159 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
10160 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
10161 From Eric Sharkey.
10163 2001-10-10 Akim Demaille <akim@epita.fr>
10165 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10166 m4_define, since...

10186 (&parse_args): Pass verbosity/debugging options to subtools when
10187 --debug, not when --verbose.
10188 * lib/autom4te.in (Autoreconf-preselections): New.
10189 (Autoconf): Use it.

10203 (Syntax of the shell scripts): Don't.
10204 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
10205 bother with $force since...
10206 * lib/Autom4te/General.pm: does.
10208 2001-10-08 Akim Demaille <akim@epita.fr>

10297 ourselves with CONFIG_SHELL.
10299 2001-10-05 Paul Eggert <eggert@twinsun.com>
10301 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
10302 doesn't exist. Remove *.tmp, as a .tmp file is created during the

10344 compatibility with POSIX shells.

10384 and invoke a new argument $4 if either is discovered.
10385 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
10386 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10418 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
10419 (AC_PROG_CPP requires AC_PROG_CC): here and...
10420 * tests/fortran.at (GNU Fortran 77): there.
10421 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10422 AC_TRY_RUN is about compilation, not shell commands.
10423 (Test Programs): AC_TRY_RUN works as used to be advertised.
10425 2001-09-27 Akim Demaille <akim@epita.fr>
10427 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10428 Raja R Harinath:
10429 Be sure to detect when $LINENO always returns the same value.
10430 Look for the original script, basename($0) is certainly not
10431 enough.
10432 Pass the CLI arguments to `$as_me.lineno'.

10453 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
10454 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10455 builddir, buildpath, top_builddir, and top_buildpath.
10456 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10457 the current directory.

10482 * doc/autoconf.texi (Common Shell Constructs): Rename as...

10529 2001-09-22 Akim Demaille <akim@epita.fr>

10534 `$LINENO' support replacement when not supported.
10535 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke

10546 character (u: -> ue) in a code comment.
10547 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know

10575 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10577 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

10580 arguments. Fixed a typo.
10582 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10584 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

10598 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10599 already have $file). Set output files to binary mode (helps avoid
10600 CR issues on DOSish systems).
10602 2001-09-19 Akim Demaille <akim@epita.fr>
10604 * lib/autotest/general.m4: Englishoes.
10605 From Tim Van Holder and Alexey Mahotkin.
10607 2001-09-18 Paul Eggert <eggert@twinsun.com>
10609 * doc/autoconf.texi (Common Shell Constructs): New node,
10610 documenting AS_DIRNAME.
10611 (Limitations of Usual Tools): Refer to it when discussing dirname.
10612 Also, update discussion of POSIX standard to reflect latest draft.
10614 * lib/autoconf/c.m4:
10615 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10617 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10618 Do not pass a first argument with leading '-'
10619 to expr, by parenthesizing initial integers that might be negative.
10621 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10622 now merely checks whether it is an error to pass an argument
10623 to getpgrp.
10625 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10626 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10627 whether it is a (compile-time) error to pass an argument to
10628 getpgrp. This simpler test supports the revised documentation,
10629 and is all that AC_FUNC_GETPGRP's users really need.
10631 2001-09-18 Akim Demaille <akim@epita.fr>

10644 correctly.
10645 Add test for AS_BASENAME.
10646 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10647 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10648 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10649 * tests/base.at: Fixed the expected responses. The old ones were
10650 one line out...
10651 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10652 the documentation claims it should (and how it behaved in 2.13).
10654 2001-09-18 Akim Demaille <akim@epita.fr>
10656 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

10665 Use `m4_PACKAGE_STRING'.
10666 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10667 the only optional argument is the name of the test suite.
10668 Expect `package.m4' to define the package signature.
10669 * lib/autom4te.in (Autotest): Add `package.m4?'.
10670 * tests/Makefile.am (package.m4): New.
10671 * tests/suite.at: ifnames is a victim.
10673 2001-09-18 Akim Demaille <akim@epita.fr>
10675 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10676 AC_LIBSOURCE, AC_CONFIG_FILES.
10677 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10678 program version string doesn't match the package's.
10679 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10680 after `(cached)'.

10684 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10685 Allow expression to return any value that can fit into unsigned long
10686 (not int, as before). Check for output errors.
10688 2001-09-17 Bruno Haible <haible@ilog.fr>
10690 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10691 Always include <stdio.h> and <stdlib.h>. Evaluate
10692 the expression in an extra function before these includes. Call
10693 fprintf "%d" only after ensuring the argument is of type 'int'.
10694 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10696 2001-09-17 Paul Eggert <eggert@twinsun.com>
10698 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10699 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10700 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10701 when they don't exist.
10703 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10704 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10705 need it.
10707 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10708 version with the version used by fileutils 4.1, except use
10709 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10710 we don't need it.
10712 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10714 2001-09-13 Akim Demaille <akim@epita.fr>
10716 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10717 _first_.

10754 * lib/autotest/general.m4 (AT_INIT): Create and remove
10755 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10756 test suites can cohabit.

10828 2001-09-07 Akim Demaille <akim@epita.fr>

10831 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
10832 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
10833 related variables into `at_package_*'.

10843 Move toward possibly stand-alone test suites.
10845 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
10846 in addition, it introduces useless differences in logs.

10848 Adjust PATH computation.
10849 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

10866 2001-09-05 Akim Demaille <akim@epita.fr>
10868 Be ready to handle filenames as stupid as `dnl.at', for if even
10869 the maintainer is dumb enough to do that...
10871 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10872 excellence in M4 quotation: consider `__file__' is active.
10874 And BTW, when invoking m4, pass the --include in the right order:
10875 the wrong one.
10877 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
10878 4m.

10888 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

10902 CVS GNU M4 doesn't like `undefine(undefined)'.
10904 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
10905 New, extracted from main.
10906 Use IO::File wherever possible.
10907 (input.m4): Be constant, use -I instead of hard coding $tmp.
10908 Therefore be a quoted heredoc.
10909 Don't invoke `_au_disable', since ac was not loaded, but just
10910 `unm4.m4'.
10912 2001-08-31 Akim Demaille <akim@epita.fr>
10914 Version 2.52d.

10937 2001-08-31 Akim Demaille <akim@epita.fr>
10939 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10940 (testsuite Scripts): There is no such thing as `atconfig.in'.
10941 And actually one diagram is missing: test suite runtime.
10943 2001-08-31 Akim Demaille <akim@epita.fr>
10945 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10946 inverse order.
10948 2001-08-31 Akim Demaille <akim@epita.fr>
10950 * bin/autoupdate.in (@include): `installcheck' revealed the path
10951 to m4sugar was lacking!
10953 2001-08-31 Akim Demaille <akim@epita.fr>
10955 * man/Makefile.am (.x.1): We really have to pass
10956 autom4te_perllibdir.
10958 2001-08-31 Akim Demaille <akim@epita.fr>
10960 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10961 debug scripts, in particular passing explicitly listed tests to
10962 run is stupid.
10964 2001-08-31 Akim Demaille <akim@epita.fr>
10966 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10967 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10968 Use directly autom4te, not autoconf.

10971 2001-08-31 Akim Demaille <akim@epita.fr>
10973 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

10982 * bin/autom4te.in (&parse_args): Die on unknown languages.
10983 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10984 need for autoconf.
10985 Promote --include over --macrodir and other obsolete options.
10987 2001-08-31 Akim Demaille <akim@epita.fr>
10989 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

10991 * bin/autom4te.in ($autoconf): Pass --force.
10992 `print $out' doesn't print `$_' but `$out'.
10993 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10994 (autoheader): Pass --force since the test suite goes too fast for
10995 the time stamps.
10996 Adjust to the new autoheader messages.
10998 2001-08-31 Akim Demaille <akim@epita.fr>
11000 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11001 Check the completeness of the #template.

11010 Drop AC_MACRODIR dead for real.
11011 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11012 `autoheader: `config.hin' is created'.
11013 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11015 2001-08-31 Akim Demaille <akim@epita.fr>
11017 * bin/autoheader.in: Rewrite in Perl.

11020 2001-08-31 Akim Demaille <akim@epita.fr>
11022 * bin/autoconf.in (--include, -I): New option.
11023 Map --localdir, --autoconf-dir onto it.
11024 Forward autom4te's options instead of interpreting them.
11025 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11026 There is no such envvar since the inception of autom4te.cfg.
11027 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11028 * bin/autoupdate.in: Adjust, and perform more control.
11029 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.

11032 2001-08-31 Akim Demaille <akim@epita.fr>
11034 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11035 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11036 optionally `FILE'.
11037 Use -e, not -f, since /dev/null for instance is OK.
11038 (&parse_args): Adjust.
11039 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11041 2001-08-31 Akim Demaille <akim@epita.fr>
11043 * configure.ac: Also find tested executables in bin.
11044 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11045 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11046 installed peer executables, only PATH is allowed to resolve it.
11047 Pass `autoconf_dir' via options, not via invisible envvars.
11048 * lib/Autom4te/General.pm (&find_peer): Remove.
11049 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11050 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11051 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11052 find the executables for it.
11053 * tests/Makefile.am: Major cleanup. Too lazy to document...
11054 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11055 We only need PERL.
11056 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11057 indeed related to running the test suite, while passing
11058 --autoconf-dir and others is related to running non installed
11059 Autoconf executables. So don't do that, leave it to...
11060 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11061 * tests/autoscan: New.
11062 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11063 refer to library files: rely on --language.
11065 2001-08-29 Akim Demaille <akim@epita.fr>
11067 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11068 s/--set/--language/.
11070 2001-08-29 Akim Demaille <akim@epita.fr>
11072 * doc/autoconf.texi: Strip the @nodes.
11073 Suggested by Paul Eggert.

11076 2001-08-29 Akim Demaille <akim@epita.fr>
11078 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11079 Suggested by Paul Eggert.
11081 2001-08-29 Akim Demaille <akim@epita.fr>
11083 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11084 download in a tmp dir.
11086 2001-08-29 Akim Demaille <akim@epita.fr>
11088 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11089 case insensitive OSes out there :(

11099 (&parse_args): Support --mode, --set, and --melt.
11100 * bin/autoconf.in: Simplify and adjust.
11101 * tests/Makefile.am (AUTOMAKE): Use --set.
11102 * tests/atlocal.in: Adjust.
11103 * BUGS: distcheck and check are weak.
11105 2001-08-29 Akim Demaille <akim@epita.fr>
11107 * lib/autotest/general.m4: Use
11108 foo=`(command) 2>/dev/null`
11109 not
11110 foo=`command` 2>/dev/null
11111 (at-devnull): Rename as...
11112 (AT-devnull): this.
11113 (--clean): Remove AT-* files too.
11114 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11115 Reported by Nicolas Joly.

11125 * doc/autoconf.texi (Function Portability): Mention C right shifts.
11127 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
11129 * lib/autotest/general.m4: Reword some messages.
11130 (AT_INIT): Check for the `times' builtin before using it.
11131 Support test ranges as arguments to the testsuite.
11132 Have -e imply -d as the help text suggested.
11134 2001-08-27 Akim Demaille <akim@epita.fr>
11136 * Makefile.maint: Formatting changes.

11586 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
11587 endianness for comparison instead of relying on AT_CHECK_ENV.
11589 2001-08-11 Paul Eggert <eggert@twinsun.com>
11591 * doc/autoconf.texi, doc/install.texi: Add a copyright notice

11623 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11625 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11627 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11628 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11629 * doc/autoconf.texi (C Compiler Characteristics): Update
11630 documentation for AC_C_BIGENDIAN.
11632 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11634 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11635 magic values from an object file when cross-compiling.
11636 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11638 2001-08-10 Akim Demaille <akim@epita.fr>
11640 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11641 effects.
11642 Suggested by Russ Allbery.
11644 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11646 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11647 current $prefix to the sub-configures.
11649 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11651 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11652 extension (needed on BeOS). Reported by Guido van Rossum.
11654 2001-08-09 Akim Demaille <akim@epita.fr>
11656 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11658 2001-08-07 Akim Demaille <akim@epita.fr>
11660 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11661 removed.
11662 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11663 No need to remove the files before and after the each test, before
11664 each test and at the end of the suite is enough.
11665 Display only the children `times', not the shell's.
11666 If the test failed or was skipped, at-times is not available.
11668 2001-08-07 Akim Demaille <akim@epita.fr>
11670 Always produce testsuite.log, including when there are no
11671 failures. This helps getting information on skipped tests, and
11672 duration of the tests. Err, implement the latter btw.
11674 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11675 Dump information on the first run of each test.
11676 (AT_CLEANUP): Create `at-times' containing the duration of the
11677 test group.
11679 2001-08-07 Akim Demaille <akim@epita.fr>
11681 The use of `dumpstat' revealed that `len' was used although it
11682 should not. m4_text_wrap was using it, but in the Autoconf world
11683 where it is legal. Hence (i) test M4sh in its own world, not
11684 Autoconf's, and (ii), ahem, fix the bug :)
11686 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11687 does not like `' instead of [].
11688 (AT_INIT): Forbid `^_?AT_'.
11689 And don't output such tokens.
11690 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11691 `script.as', and `autom4te.cache'.
11692 Remove `empty' and `macro' which are no longer used.
11693 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11694 * tests/m4sugar.at: Use it.
11695 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11697 2001-08-07 Akim Demaille <akim@epita.fr>
11699 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11701 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11703 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11705 2001-08-04 Akim Demaille <akim@epita.fr>
11707 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11708 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11709 AC_TRY_LINK.
11710 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11711 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11712 (AC_F77_MAIN): Likewise.
11714 2001-08-04 Akim Demaille <akim@epita.fr>
11716 Don't rely on M4sugar outputting the patterns in files, since we
11717 might process the output _without_ running m4, hence without these
11718 files.
11720 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11721 * bin/autom4te.in (@Request::includes): Remove, unused.
11722 (@Request::source): Rename as...
11723 (@Request::input): this.
11724 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11725 (&handle_output): Fetch the patterns from the traces.
11726 `$forbidden' and `$allowed' are constant: use m//o.
11727 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11728 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11730 2001-08-04 Akim Demaille <akim@epita.fr>
11732 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11733 autoconf', i.e., in addition to caching traces, cache the output.
11735 * bin/autom4te.in (Request::cache): Rename as...
11736 (Request::id): this.
11737 ($cache, $icache, $tcache, $ocache): New.
11738 (&handle_m4): Save M4 output in the cache instead of $tmp.
11739 (&handle_output): Adjust.
11740 (&up_to_date_p): Check that the output cache is up to date too.
11741 (top level): Run `&handle_m4' iff force or the cache is invalid.
11742 Run `&handle_output' if the output cache is more recent.
11744 2001-08-04 Akim Demaille <akim@epita.fr>
11746 * bin/autom4te.in ($force): New.
11747 (&parse_args, &print_usage): -f, --force is a new option.
11748 (&handle_output): CPP directives might have spaces after `#'.
11749 (&parse_args): The first file only can be frozen.
11751 2001-08-04 Akim Demaille <akim@epita.fr>
11753 Don't let autom4te compute the `include' traces several times:
11754 first check that the trace cache file is up to date, and then
11755 compare its timestamp with that of the output.
11757 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11758 the preamble. Don't require 5.005 as Autom4te::General does it,
11759 and better yet (use `use', not `require'!).
11760 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11761 Class::Struct as Autom4te::Struct.
11762 * lib/Autom4te/General.pm (File::stat): Use it.
11763 (&mtime): New, export it.
11764 * bin/autom4te.in: Use it.
11765 Declare `$req' is invalid if it is outdated.
11766 Don't declare it valid before saving it if something went wrong.
11768 2001-08-04 Akim Demaille <akim@epita.fr>
11770 Autom4te shall not encode Autoconf data, and preselecting traces
11771 must be proposed to the users.
11773 * bin/autom4te.in (@required_trace): Remove.
11774 (@preselect): New.
11775 (&parse_args, &print_usage): -p, --preselect is a new option.
11776 (&up_to_date_p): Adjust.
11777 * bin/autoconf.in: Preselect some Autoconf macros.
11779 2001-08-04 Akim Demaille <akim@epita.fr>
11781 * tests/tools.at (autoconf --trace: user macros): Check traces on
11782 macros invoked without arguments, and macros invoked with multiple
11783 lines arguments.
11785 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11787 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11788 arguments.
11790 2001-08-03 Akim Demaille <akim@epita.fr>
11792 * bin/autoconf.in ($@): Work around the usual sh bug.
11793 From Nicolas Joly.
11795 2001-08-03 Akim Demaille <akim@epita.fr>
11797 Clean up the handling of the M4 builtins tracing exception.
11799 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11800 trace requests.
11801 (@m4_builtins): Rename as...
11802 (@m4_builtin): this.
11803 (%m4_builtin_alternate_name): New.
11804 (&parse_args): Complete the trace requests with alternate names.
11805 (&handle_traces): Hence no longer do it here.
11806 (&trace_requests): Remove, unused.
11808 2001-08-03 Akim Demaille <akim@epita.fr>
11810 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11811 m4_if, and m4_wrap.
11813 2001-08-03 Akim Demaille <akim@epita.fr>
11815 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11816 (m4_divert_pop): Dump the whole diversion stack when a diversion
11817 mismatch happens.
11818 * bin/autom4te.in (&handle_output): Remember of the first
11819 occurrence of a possibly undefined macro, not the last.
11820 Complain about the possibly undefined macros in the same order as
11821 the appear in the output.
11822 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11823 * tests/tools.at (autoconf: forbidden tokens, basic)
11824 (autoconf: forbidden tokens, exceptions): No longer sort
11825 autoconf's stderr, as it is now deterministic.
11826 Check that `dnl' is caught.
11828 2001-08-01 Akim Demaille <akim@epita.fr>
11830 * configure.ac: Bump to 2.52c.
11832 2001-08-01 Akim Demaille <akim@epita.fr>
11834 Version 2.52b.

11842 2001-08-01 Akim Demaille <akim@epita.fr>
11844 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
11845 `die'.
11846 (&END): New.
11847 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11848 `END', as `Autom4te::General::END' will be triggered.
11849 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11850 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12285 cross-language link tests can be performed successfully.
12286 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12287 after $LIBS, for consistency; this should be the general rule since
