1 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
3 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
4 that traditional Awk lacks 3-arg "split". It has it.
5 Mention that FS must be a single character, and a few other
6 99-byte limits of traditional Awk.
8 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
10 * tests/autotest.at (BSx641-newline in command):
11 (BS-BS-newline in command, BSx640-newline in command):
12 (Newline-CODE-BS-newline in command):
13 (Single-quote-BS-newline in command):
14 (Single-quote-newline-BS-newline in command):
15 Use printf '%s\n' instead of echo, for portability to hosts
16 where echo interprets backslashes. This will break on hosts
17 that lack printf, but for now let's assume all such hosts
18 are dead (if not, we should get reports of test failures).
20 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
22 'echo' has some portability problems, when given a first argument
23 with a leading '-', or when given any argument containing '\'.
24 Avoid using 'echo' in these cases.
25 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
26 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
27 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
28 * lib/autotest/general.m4 (AT_INIT): Likewise.
29 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
30 argument might be unportable.
31 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
32 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
33 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
34 (_AC_FC_LIBRARY_LDFLAGS): Likewise.

45 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):

48 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
49 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
50 * bin/autoconf.as: Redo verbose flag implementation, as the old
51 scheme wouldn't work with AS_ECHO.
52 * lib/autotest/general.m4 (AT_INIT): Likewise.
53 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
54 Don't use ECHO_T, since ECHO_N is now reliable.
55 * lib/autotest/general.m4 (AT_INIT): Likewise.
56 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
57 rather than using a here-document to put the script into a file.
58 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
59 use AS_ECHO.
60 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
61 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
62 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
63 bug, but we might as well stop using ECHO_N and ECHO_C internally.
64 * lib/autotest/general.m4 (AT_SETUP): Likewise.
65 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
66 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
67 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
68 operand, as AS_ECHO requires. Avoid double file name expansion.
69 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
70 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
71 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
72 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
73 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
74 Double-quote strings that would otherwise contain M4 comments.
75 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
77 * configure.ac (AC_INIT): Bump to 2.61a.
78 * NEWS: Likewise.
80 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
82 Version 2.61.
84 * configure.ac (AC_INIT): Bump to 2.61.
85 * NEWS: Likewise.
87 * tests/autotest.at (Macro with backslash in a test title):
88 Comment out for now, as this tests neither fails nor passes
89 reliably. Problem reported by Ralf Wildenhues.
91 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
93 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos

146 as well as pdf images, since they are supported in pdftex with
147 no further ado.
149 2006-11-05 Karl Berry <karl@gnu.org>
151 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

168 benefit of platforms like Solaris+GCC where it is common to have a
169 non-working g++ installation.

172 and Joel E. Denny <jdenny@ces.clemson.edu>
173 and Paul Eggert <eggert@cs.ucla.edu>
175 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
176 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
177 ./micro-suite.
179 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
181 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
182 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
183 Imported from a similar patch to gnulib by Bruno Haible.
185 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
187 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

201 Automake 1.10 nor future Automake 11.1 (sic).
203 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
204 and Stepan Kasal <kasal@ucw.cz>
206 Handle special characters in test case titles correctly.
207 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all

209 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
210 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
211 argument. Extend to check titles printed by ./micro-suite and
212 ./micro-suite -l and the title in micro-suite.log.

214 Single-quote in a test title,
215 Double-quote in a test title): Don't expect failure anymore.
216 (Backslash in a test title): Put a non-whitespace character after the
217 backslash so that Bourne shells might actually see it as an escape
218 sequence.
219 (Brackets in a test title,
220 Pound in a test title,
221 Comma in a test title,
222 Quoted Macro in a test title,
223 Macro in a test title,
224 Macro with single-quote in a test title): New tests.
225 (Macro with backquote in a test title,
226 Macro with double-quote in a test title,
227 Macro with backslash in a test title): New tests expected to fail.
228 * tests/torture.at (#define header templates): M4-quote this title in
229 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
230 The visible effect was a stray [] in the testsuite output.
232 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
234 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
235 `trap ... 0' inside a function, for AIX sh.
237 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
239 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
240 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
241 5363) simply issues a warning when dividing by zero at compile
242 time. Problem reported by Elias Pipping.
244 2006-10-26 Eric Blake <ebb9@byu.net>
246 * THANKS: Update.
247 * doc/autoconf.texi (Evaluation Macros): Improve the example to
248 show effect on macros that expand with commas.
249 Reported by Joel E. Denny.

273 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
275 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
276 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
277 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
278 reported by Nelson H. F. Beebe for Coreutils 6.4.
280 * tests/tools.at (autoconf --trace: user macros): Remove test
281 for tracing multiline macros, since m4 1.4.7a uses a different
282 way to number lines. Problem reported by Ralf Wildenhues.
284 2006-10-24 Stepan Kasal <kasal@ucw.cz>
286 * bin/autom4te.in (handle_m4): Do not redirect stdin to
287 /dev/null since the heuristics for interactive behaviour was
288 fixed in CVS m4.
290 * bin/autom4te.in: With --force, always refresh the output
291 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
293 * bin/autoconf.as: Fix the verbose message at the end.
295 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

309 * doc/autoconf.texi (Caching Results): Likewise.

311 AC_CACHE_CHECK_INT, since it's no longer public.
312 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
313 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
315 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

322 (m4_maketemp): Avoid warnings with M4 1.9a.
323 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
324 m4_mkstemp.
325 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.
326 * NEWS: Likewise.
328 2006-10-16 Eric Blake <ebb9@byu.net>
330 * doc/autoconf.texi (Setting Output Variables): Fix typo.
332 * bin/autoconf.as (version): Reword to match GNU Coding
333 Standards.
334 * bin/autoheader.in (version): Likewise.
335 * bin/autom4te.in (version): Likewise.

341 2006-10-14 Stepan Kasal <kasal@ucw.cz>
343 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
344 looking for special shell characters.
345 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
346 macro defined by AS_VAR_PUSHDEF before passing it as a
347 parameter.
348 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
349 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

358 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
360 (Imported from Automake.)
361 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
362 which incorrectly sets the mode of an existing destination
363 directory. In some cases the unpatched install-sh could do the
364 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
365 system. We hope this is rare in practice, but it's clearly worth
366 fixing. Problem reported by Alex Unleashed in
367 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
368 Also, don't bother to check for -m bugs unless we're using -m;
369 suggested by Stepan Kasal.
371 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>

378 Report from Bruno Haible.
380 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
381 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in

384 Import this change from Config:
386 2006-09-20 Ben Elliston <bje@gnu.org>
387 * build-aux/config.sub (score, score-*): New.
389 Import this change from Gnulib:
391 2006-09-16 Karl Berry <karl@gnu.org>
392 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
393 to avoid sectioning errors.
395 Import these changes from Texinfo:
397 2006-10-04 Karl Berry <karl@gnu.org>
398 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.
399 (\quoteexpand): rename to \rquoteexpand.
400 (\codequoteleft): new def, to look for @set codequotebacktick.
401 (\lquoteexpand, \quoteexpand): new defs.
402 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
403 (\code): must use new \...Char values, since now ` is active.
405 2006-08-26 Karl Berry <karl@gnu.org>
406 * build-aux/texinfo.tex (\textdegree): New command.
408 2006-08-12 Karl Berry <karl@gnu.org>

413 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
415 2006-10-13 Stepan Kasal <kasal@ucw.cz>
417 * doc/autoconf.texi (Autoheader Macros): Warn that the text
418 added to the template can get mangled.
420 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
422 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
423 include the default headers, and redefine obstack_chunk_alloc
424 and obstack_chunk_free. Fixes false failure with glibc.
426 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
428 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
429 for backward compatibility with Libtool 1.5.22. Problem reported
430 by Ralf Wildenhues.
432 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
434 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
435 AC_PROG_CC.
436 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
438 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>

441 the NonStop platform.
442 * doc/autoconf.texi (Posix Variants): Likewise.
443 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
445 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
446 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
447 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
448 Use a better substitute, by inspecting the output of "ls"
449 rather than just using ":".
450 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
451 rather than AS_EXECUTABLE_P, since we needn't worry about
452 non-regular files here.
454 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
455 due to configuration hassles with this. See Tonya Underwood's report
456 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

479 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
480 comment about ac_cpp_err; it was incorrect, and anyway
481 ac_cpp_err is being removed below.
482 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
483 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
484 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
485 nobody uses it.
486 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
487 with werror_flag and conftest.err and so forth. This is more
488 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
489 and anyway the user shouldn't normally want to see this gorp logged.
490 Problem reported by Ralf Wildenhues.
491 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
492 empty, not 'no', since the rest of the code uses 'test -z'.
494 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
496 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
497 Use a single call to AC_DO_TOKENS rather than multiple, for
498 efficiency.
499 (_AC_LINK_IFELSE): Test that resulting file is executable.
500 Problem reported by mwoehlke in
501 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
503 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
504 than creating a file to use with test -x; this is much faster.
506 2006-10-02 Bruno Haible <bruno@clisp.org>
508 * lib/autom4te.in (Automake-preselections): Add
509 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
511 2006-09-27 Stepan Kasal <kasal@ucw.cz>
513 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for

516 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
518 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
519 fseeko testing program twice; just use the earlier result.
520 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
521 Set cache var to 'unknown' (not 'no') if leaving the macro unset
522 still doesn't let the program compile.

524 failed.
526 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.

530 expressions.
531 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.

535 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
536 `error.h', and include it, for a `error_at_line' prototype.
537 Use a nonempty format string in the link test.
538 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
539 for a declaration of wait3.
541 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>

544 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
545 can apply to constants too, and that it checks for macro defns.
546 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
547 and simply cast the identifier to void. This handles structure
548 values. Problem reported by Ralf Wildenhues.

551 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

604 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
605 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
606 --error-output, to avoid warnings with M4 2.0.
608 2006-09-19 Stepan Kasal <kasal@ucw.cz>
610 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

637 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
638 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
639 for the existence of the directory at configure-time. That's
640 too late, anyway. Problem reported by Stefan Seefeld.
642 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
643 7.1.4 /usr/bin/posix/sh described by Tim Rice in
644 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
646 2006-09-11 Stepan Kasal <kasal@ucw.cz>
648 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
649 works with GNU M4 1.4.3 again; make the normalized form
650 match the current m4 message; fix the description.

656 to catch glibc bug 2821
657 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
659 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
660 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
661 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
662 assume C89.
664 2006-09-08 Stepan Kasal <kasal@ucw.cz>
666 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

759 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
760 deal with LEXLIB.
761 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
762 didn't work if some values were cached but not others. Test for
763 broken lex libraries like native ia64-hp-hpux11.22; see
764 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
765 work around the problem by preferring an empty LEXLIB to -lfl or
766 -ll. Let the user set LEXLIB='' to indicate no library needed.
768 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
769 * README: Likewise.

928 * doc/autoconf.texi (config.status Invocation): Adjust according
929 to last change.
931 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
933 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
934 --help' should mention that `--version' outputs configuration
935 settings. Report by Bruno Haible.
937 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
939 Fix test suite failures reported by Pierre in
940 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
941 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
942 the compiler created a file "b.out" when it didn't create anything
943 at all.
944 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
945 Discard stderr too, when invoking the test script.
947 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
949 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
950 in the restoring of the werror flag.
952 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
954 * doc/autoconf.texi (Volatile Objects): Be even a little
955 less skeptical about "volatile", after discussion with
956 Bruno Haible on bug-gnulib.
957 (Limitations of Usual Tools): Warn about sed stripping
958 leading white space from text. From Bruno Haible.
960 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
962 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
963 compiler complains about it, even if things works after the
964 complaint. Problem reported by Peter O'Gorman.
966 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
967 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
968 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
970 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
972 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
973 after -R regardless of host. Patrick Welche reports that this
974 fixes things on NetBSD 3.99.
976 * NEWS: Recommend M4 1.4.5.
977 * README: Likewise.
978 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
979 * tests/tools.at (autom4te cache): Update wording of diagnostic
980 to match M4 1.4.5.
982 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
984 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
985 under AC_C_VOLATILE.
986 (Volatile Objects): Be a little less skeptical about what
987 "volatile" means. Derived from thoughts by Ben Pfaff in
988 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
990 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
992 * doc/autoconf.texi: Fix some typos.
994 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
996 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
997 more globally, since the 2006-06-30 patch didn't suffice. Problem
998 reported by Keith Marshall. Also, don't bother with builddir2,
999 since it shouldn't be needed any more.
1001 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1003 * doc/autoconf.texi (Generic compiler characteristics):
1004 Document AC_COMPUTE_INT. Fix wrong statements on Default
1005 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1007 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1008 (_AC_COMPUTE_INT): Add obsoletion warnings.
1009 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
1010 AC_COMPUTE_INT.
1012 * NEWS: Document change.
1014 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1016 * doc/autoconf.texi (Volatile Objects): New section.
1018 * NEWS: Document previous change.
1020 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1022 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1023 Require that long long int be at least 64 bits wide. C99 requires
1024 this and enough programs depend on it so we should check for it.
1025 Bruno Haible reports in
1026 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1027 that long long int is 32 bits wide with some nonstandard compilers.
1028 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1030 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1032 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1033 to a nonexistent file, so that we don't have to worry about
1034 a local site configuration that doesn't use /usr/local.
1035 Problem reported by Keith Marshall in
1036 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1038 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1040 * doc/autoconf.texi: Be more consistent about using @acronym with
1041 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1042 quite right (it talked about "OSF/Tru64", even though the
1043 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1044 and it even mentioned "OSF 4"!) and at this point there's little
1045 reason to talk about OSF any more, since it died in 1994.
1046 (Specific Compiler Characteristics): Simplify example of
1047 negative-size array.
1048 (File Descriptors): Reorder to make the text flow better.
1049 Remove joke about "appreciate the various levels"; I didn't get it.
1050 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1051 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1052 (File Descriptors, Limitations of Usual Tools):
1053 Tone down the advice against renaming or removing open files.
1054 (Limitations of Usual Tools): Add a new section, on 'rm'.
1056 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1058 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1059 -lXt in LIBS, idea from Karsten Hopp; this was due since
1060 this change:
1062 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1063 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1064 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1065 (which belong to Xt, not X itself). See Debian bug 327655.
1067 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1069 * configure.ac (AC_INIT): Bump to 2.60a.
1070 * NEWS: Update.
1072 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1074 Version 2.60.
1076 * configure.ac, NEWS: Update.
1078 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1080 * config/texinfo.tex: Sync from upstream.
1082 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1083 quadrigraph correctly in traces.
1085 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1086 Fix typos.
1088 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1089 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1090 not defined.
1091 * doc/autoconf.texi (Changed Directory Variables): New node,
1092 to document the whole `datarootdir' business a bit better.
1093 * NEWS: Update.
1094 * tests/torture.at (datarootdir workaround): Extend test.
1095 Prompted by report by Alexandre Julliard.
1097 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1099 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1100 when using default mode of IBM C 6 for AIX. Problem and two-line
1101 fix reported by Larry Jones.
1103 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1105 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1106 about literal '${datarootdir}' if a definition is found in the
1107 output file.
1109 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1111 * NEWS: Use "M4" rather than "m4" when appropriate.
1112 Problem reported by Eric Blake.
1113 * doc/autoconf.texi: Likewise.
1114 Use @acronym around BSD, GCC, and GNU when appropriate.
1115 (Why GNU M4): Renamed from "Why GNU m4".
1116 (Redefined M4 Macros): Mention that Posix
1117 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1118 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1119 to int.
1121 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1123 * bin/autom4te.in (handle_output): Do not forbid the empty
1124 pattern.
1125 * tests/tools.at (autoconf: the empty token): New test.
1127 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1129 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1130 calls, so that we do not care whether they are LIFO or FIFO;
1131 in the m4_wrap, do not check which diversion is the topmost
1132 one, just check that the stack is balanced at the end.
1133 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1134 base diversion forever--pop the previous diversion before
1135 opening the new one; consequently, remove the m4_wrap call.
1136 * lib/autotest/general.m4 (AT_INIT): Likewise.
1137 * tests/m4sugar.at: Do not use
1138 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1140 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1141 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1143 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1144 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1145 Rework example of m4wrap token-pasting trouble so that it doesn't
1146 care whether it's LIFO or FIFO.
1147 Fix some "contrary to"s that are awkward in English.
1149 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1151 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1152 to `yes' instead of `int$1_t' if the type is found, for more
1153 consistent configure output (where $1 is the number of bits).
1154 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1155 Suggested by Bruno Haible.
1157 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1158 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1159 with system headers. Report by Bruno Haible.
1161 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1163 * config/config.guess, config/config.sub: Sync from upstream.
1165 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1166 in order to avoid picking up an older installed frozen m4sh.m4f.
1167 Besides an outdated shell startup, this could have been created
1168 by an earlier M4 version with incompatible frozen file format.
1170 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1172 * README: Recommend m4 1.4.4 instead of 1.4.3..
1173 * doc/autoconf.texi: Likewise.
1174 (Special Chars in Names): Say that $(.FOO) is portable, as
1175 suggested by Stepan Kasal.
1176 (Installation Directory Variables, Build Directories):
1177 (Automatic Remaking, Subdirectories, Fortran Compiler):
1178 (Making testsuite Scripts, Defining Directories):
1179 Quote variable usages better.
1180 (Making testsuite Scripts): Add clean-local rule to makefile
1181 snippet, by Eric Blake.
1182 (Installation Directory Variables): Fix table item font.
1183 Reword slightly to clarify. Generalize advice about
1184 not using special characters to include all file-related
1185 vars, not just VPATH.
1186 (Special Chars in Variables): Warn about special characters in
1187 $(srcdir) too.
1188 (Assignments): Clarify default-value example as suggested by
1189 Ralf Wildenhues in
1190 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1191 (Special Shell Variables): Note leading ./ or ../, as suggested
1192 by Eric Blake.
1193 (Limitations of Builtins): Under cd, warn about CDPATH.
1194 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1195 Ralf Wildenhues.
1197 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1199 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1200 `@var', for texi2html.
1201 (Systemology): Some more word wrapping, for DVI output.
1202 (autom4te Invocation): The short option for `--melt' is `-M',
1203 not `-m'.
1205 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1207 * doc/autoconf.texi: More formatting and English tweaks,
1208 many suggested by Ralf Wildenhues.
1209 Reword to avoid "@code{...}'s" and the like, since it's ugly
1210 with Emacs info mode. discontents -> woes.
1211 Put a few "will"s back. time stamp -> timestamp.
1212 side-effect -> side effect.
1214 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1216 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1217 Warn about $@ not persisting. Problem reported by Julien Danjou in
1218 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1219 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1220 Mention other special chars, too.
1222 2006-06-14 Eric Blake <ebb9@byu.net>
1224 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1226 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1228 * doc/autoconf.texi: Some systematic minor improvements, as
1229 follows. Use "makefile" when talking about makefiles
1230 generally (which might be named "makefile" or "Makefile" or even
1231 "foo.mk"), "Makefile" when talking about a specific makefile
1232 called "Makefile". This unclutters the text from weird quotes
1233 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1234 values" rather than "@var{foo}s" and similar constructs containing
1235 "}s". Use "Make rules" rather than "Makefile rules". Minor
1236 English-language improvements. Change the prefix "sub-" to "sub"
1237 and "re-" to "re".
1238 Put blank lines around examples more consistently.
1239 Avoid "rather" and "very" as intensifiers.
1240 Avoid "will" as an auxiliary.
1241 (Limitations of Make): Split this node into....
1242 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1243 (Leading _ in Macro Names, Backslash-Newline-Newline):
1244 (Backslash-Newline Comments, Long Lines in Makefiles):
1245 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1246 (obj/ and Make, make -k Status, VPATH and Make):
1247 (VPATH and Double-colon, $< in Explicit Rules):
1248 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1249 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1250 New nodes, resulting from splitup of Limitations of Make.
1251 All cross-references changed. Raise the top node from
1252 a section to a chapter, and all subnodes accordingly.
1253 Redo the introductory wording to match the new organization.
1254 (Installation Directory Variables): Use an example that is
1255 closer to what Autoconf actually does. Mention that VPATH's
1256 value should not contain metacharacters or white space.
1257 (Fortran Compiler): Fix a VPATH bug in an example.
1258 (Leading _ in Macro Names): Mention that this problem is no longer
1259 of practical concern.
1260 (VPATH and Make): Reword the advice to make it clearer
1261 that Autoconf and Automake support VPATH in non-GNU make, but
1262 many packages have bugs in this area.
1263 ($< in Explicit Rules): Refer to Build Directories rather
1264 than using a (non-VPATH-safe) example.
1265 (Automatic Rule Rewriting): Mention the sort of disaster that
1266 can ensue with Solaris-style rule rewriting with VPATH.
1268 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1270 * doc/install.texi (Compilers and Options): Weaken the
1271 suggestion to use GNU make for VPATH builds.
1273 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1274 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1276 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1277 in regular expression.
1279 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1281 * doc/autoconf.texi (Installation Directory Variables):
1282 Drop extra @samp from `@table @samp' item.
1283 (Limitations of Usual Tools): Comment fix.
1284 Do not nest @samp just to point to other table items.
1285 (Writing testsuite.at) <AT_CHECK>: The second argument to
1286 `@dvar' is already @samp'ed.
1287 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1288 do not use @var in the second argument.
1290 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1292 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1293 $as_shell.exe too. Problem reported by Andreas Buening in
1294 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1296 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1298 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1299 `unused variable' compiler warning, for `-Wall -Werror'.
1300 Reported by Jaap Haitsma in
1301 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1303 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1305 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1306 case the compiler dumps core. Problem reported for
1307 OpenServer 5.0.7 by Tim Rice in
1308 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1309 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1310 Likewise.
1312 2006-06-06 Tim Rice <tim@multitalents.net>.
1314 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1315 "ERROR" only shows up in "make check" output if there is an
1316 error.
1318 2006-06-06 Eric Blake <ebb9@byu.net>
1320 * tests/tools.at (automatically allowed tokens): Fix typo.
1322 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1324 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1326 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1327 typically overflows on x86 CPUs, even though the C standard
1328 requires otherwise.
1330 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1332 * configure.ac (AC_INIT): Bump to 2.59e.
1333 * NEWS: Update.
1335 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1337 Version 2.59d.
1339 * config/texinfo.tex: Sync from upstream.
1341 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1342 seen, invoke libtoolize with `--ltdl' argument.
1343 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1344 * NEWS: Update.
1345 Suggested by Eric Blake.
1347 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1349 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1350 reported by Ralf Wildenhues.

1367 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1368 to...
1369 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1370 AT_CHECK_M4.
1371 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1372 `expout' as the last parameter.
1373 * tests/tools.at: Adapt to the above change.
1375 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1377 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1378 information about race-free implementations of mkdir.
1380 2006-06-04 Eric Blake <ebb9@byu.net>
1382 * bin/autoreconf.in (help): Document M4 environment variable.
1383 * bin/autoconf.as (Usage): Likewise.
1384 * bin/autom4te.in (help): Likewise.
1385 * doc/autoconf.texi (autom4te Invocation): Likewise.
1387 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1389 * NEWS: GNU make now recommended for VPATH builds.
1390 Mention that some macros are now documented to be obsolescent.
1391 * doc/autoconf.texi:
1392 Prefer "current" to "modern" to describe
1393 currently-used (albeit perhaps old-fashioned) hosts.
1394 Mention which ancient features no longer need to be worried about.
1395 setgid -> set-group-ID
1396 setuid -> set-user-ID (these are the Posix terms)
1397 Fix some misuses of "only".
1398 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1399 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1400 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1401 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1402 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):

1405 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1406 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1407 Mention that these macros are obsolescent.
1408 (Installation Directory Variables): shall -> should
1409 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1410 Mention that it's now safe to use 3 and 4.
1411 (Limitations of Usual Tools): cp -r is now specified by Posix.
1412 Omit longwinded and obsolescent discussion of cp -f.
1413 Modernize discussion of expr, ls.
1414 (Limitations of Make): Modernize discussion of VPATH builds.
1415 Mention $? as a workaround in some cases.
1416 * doc/install.texi (Basic Installation):
1417 Mention "./configure; make; make install" first. Be more
1418 specific about why this file is generic. Remove unnecessary
1419 parens. Remove misleading "only". Remove obsolete advice
1420 about csh. Don't say "configure" takes awhile; say it
1421 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1422 and CC=c99 rather than CC=c89, as these are blessed by current
1423 Posix. Recommend GNU make if doing a VPATH build.
1425 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1427 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1428 examples involving shell prompts.
1430 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1431 and Paul Eggert <eggert@cs.ucla.edu>
1433 * doc/autoconf.texi (Here-Documents): Add details about the
1434 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1435 use "here-documents" instead of "here documents".
1437 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1439 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1441 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1443 * doc/autoconf.texi (File System Conventions): Warn about ":"
1444 anywhere in directory names.
1446 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1448 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1449 about quoting the case statement, just in case.
1450 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1451 was fixed in ksh93g; reported by Ralf Wildenhues.
1453 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1455 * doc/autoconf.texi (System Services): Do not document
1456 overriding EXEEXT via ac_cv_exeext=ext.
1457 (Particular Programs) <AC_PROG_MKDIR_P>:
1458 Document that ${MKDIR_P} understands --.
1459 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1460 comment.
1462 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1464 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1465 argument with leading hyphen. Problem reported by Paul Eggert.
1467 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1469 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1470 about quoting ac_try: quote all of it, if any of it seems suspicious.
1471 This means we don't have to worry about ${ or sed any more.
1472 Also, double-quote the case statement, to work around misuses via
1473 underquoting as reported by Ralf Wildenhues in
1474 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1475 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1476 undocumented and dangerous macro.
1477 Problem reported by Ralf Wildenhues in
1478 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1480 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1482 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1483 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1484 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1486 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1488 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1489 since evidently some packages rely on the old, broken behavior.
1490 Problem reported by Ralf Wildenhues in
1491 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1492 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1493 pre-2006-05-26 definitions, but leave in the comments that
1494 these macros are dangerous and should not be used.
1495 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1496 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1497 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1498 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1499 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1501 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1503 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1504 the use of 'tr', since this is our only use of 'tr'.
1506 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1507 and Paul Eggert <eggert@cs.ucla.edu>
1509 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1510 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1512 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1514 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1515 the output file in the `${datarootdir}' test.
1517 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1518 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1520 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1521 mention of `datarootdir' in the input file(s), but literal
1522 `${datarootdir}' in the output file, and we haven't warned yet,
1523 then warn as well: the user may have (erroneously) used
1524 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1525 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1526 * tests/torture.at (datarootdir workaround): Extend this test.
1527 * NEWS: Update.
1529 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1530 and Paul Eggert <eggert@cs.ucla.edu>
1532 * doc/autoconf.texi (autoheader Invocation): The first argument to
1533 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1534 alternatives and clear up the language a bit.
1536 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1538 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1539 ac_config_guess, ac_config_sub, ac_configure.
1540 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1541 Fix typo that prevented an unnecessary space from being removed.
1542 Problems reported by Ralf Wildenhues in:
1543 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1545 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1547 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1548 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1549 Don't use the term "thread-safe" to talk about mkdir race
1550 conditions, since the problem is more a process than a thread
1551 issue. Problem reported by Stepan Kasal in:
1552 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1553 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1554 the test for 'install' more closely. Look at MKDIR_P first.
1555 Look in the PATH, and at /opt/sfw/bin.
1556 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1557 Don't bother to try mkdir -p, since we already check mkdir --version;
1558 just look at the version number. (There's no easy way to check
1559 for race-free implementations.)
1560 * tests/tools.at (autoconf: subdirectories): Adjust to above
1561 changes, since MKDIR_P now might end in "/mkdir -p".
1563 * doc/autoconf.texi (autoheader Invocation): Mention that the
1564 first arg of AC_DEFINE_UNQUOTED must be a literal.
1565 Problem reported by Ben Pfaff in
1566 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1568 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1569 * doc/autoconf.texi (Special Chars in Variables): New section.
1570 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1571 (Installation Directory Variables): Quote $(datadir) better.
1572 (Limitations of Builtins): Describe some of eval's trickiness.
1574 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1575 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1576 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1577 in front of every arg, not just trailing args. Quote apostrophes.
1578 (_AC_EVAL_ECHO): New macro.
1579 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1580 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1581 removed.
1582 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1583 exposed by quoting of eval argument. Put the command on line line
1584 so it logs better.
1585 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1586 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1587 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1588 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1589 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1590 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1591 Use eval more safely.
1592 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1593 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1594 to be replaced.
1595 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1596 lines, exposed by quoting of eval argument.
1598 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1599 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1601 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1602 initialization of `ac_cv_exeext', do not override it if it was
1603 already set, unless it was set to `no', for compatibility with
1604 Autoconf-2.13, and comment this.
1605 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1606 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1607 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1608 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1609 Document that this test may be overridden by setting
1610 `ac_cv_exeext'.
1612 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1614 Revert these two patches:
1616 2006-04-06 Eric Blake <ebb9@byu.net>
1617 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1618 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1619 2006-04-01.
1621 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1622 Clean up _AC_COMPILER_EXEEXT* macros.
1623 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1624 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1625 ac_file to the name of the default output file and call
1626 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1627 initial `rm' of the candidate files...
1628 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1629 the same list in subsequent `rm' calls, and for the temporary
1630 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1631 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1632 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1633 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1634 no longer needed) by libtool. Make it a cache check.
1635 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1636 copied here by mistake.
1637 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1638 _AC_COMPILER_EXEEXT.
1639 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1640 _AC_COMPILER_OBJEXT directly.
1641 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1643 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1645 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1646 Fix description of how the buggy `sed' works.
1648 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1650 Sync from Automake:
1652 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1653 ENOLCK. Only mention `make -j' when applicable. Only raise
1654 fatal errors when `make -j' is involved. Improve error message.
1656 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1658 * doc/autoconf.texi (Here-Documents): We now know more about
1659 the variable expansion in here documents bug.
1660 Thanks to Tim Rice and Stepan Kasal.
1662 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1663 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1665 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1667 * tests/autotest.at (Multiline command from M4 expansion):
1668 No failure to be expected if the shell quotes newlines in
1669 commands in the `set -x' output. Report by Tim Rice.
1670 * THANKS: Update.
1672 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1674 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1675 expansion in the here-documents used by config.status, as that
1676 runs afoul of the Korn shell version M-12/28/93d bug described in
1677 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1678 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1679 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1681 2006-05-23 Jim Meyering <jim@meyering.net>
1683 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1684 Fix typo introduced with 2006-04-02 change. It reversed the sense
1685 of the test.
1687 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1689 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1690 ac_dB slightly, to save bytes in the script.
1691 Max out at 50 lines, rather than 96; this is more likely
1692 (though not guaranteed) to avoid obscure 'sed' failures.
1694 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1696 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1697 `tr -d -' as bad option argument. Work around this by deleting
1698 an unrelated character.
1699 Report by Tim Rice <tim@multitalents.net>.
1701 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1702 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1703 Stepan Kasal <kasal@ucw.cz>
1705 * doc/autoconf.texi (Particular Programs): Do not promise that
1706 we always prefer the GNU version of the program, and that we
1707 search according to PATH; both rules can have exceptions.
1708 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1709 AC_PROG_SED. Move descriptions of limitations
1710 to the Limitations of Usual Tools section.
1711 (Limitations of Usual Tools) <sed>: Mention script length
1712 limitations with Solaris /usr/ucb/sed.
1713 <grep>: Fix wording for empty alternative. Mention that -c and
1714 -l should not be combined, and that -E and -F should not be
1715 combined.
1717 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1718 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1720 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1721 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1723 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1725 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1726 AC_DEFINE is now passed to m4_pattern_allow.
1727 * NEWS: Mention that; likewise for AC_SUBST.
1728 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1729 the parameter to m4_pattern_allow.
1730 * tests/tools.at: Add a check for that.
1732 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1734 * lib/autoconf/status.m4: Fix typos.
1736 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1738 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1739 only the files that this macro generates.
1741 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1743 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1744 the HP-UX sed limitation of 99 commands, labels do not count.
1745 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1746 in the comment.
1747 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1749 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1751 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1752 Import the following fix from coreutils:
1754 2006-01-13 Jim Meyering <jim@meyering.net>
1756 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1757 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1758 not double-quote uses of that variable, to accommodate the rare
1759 case in which getmntent is available in none of the libraries
1760 checked. This happens at least on FreeBSD 5.0.
1762 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1764 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1765 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1766 some other programs unwisely rely on these undocumented vars.
1767 But put in warning comments about them.
1768 Problem reported by Ralf Wildenhues in
1769 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1770 * NEWS: Document that these variables are intended to go away.
1772 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1774 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1775 and set the language to C++ (analogous to the equivalent Fortran
1776 tests).
1778 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1779 * doc/autoconf.texi (C++ Compiler): Document it.
1780 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1781 * NEWS: Update.
1783 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1785 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1786 that caused config.status to generate 100-command sed scripts; the
1787 portable limit is 99.
1789 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1791 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1792 variable `ac_d' instead of `d' to avoid infringing namespace.
1793 Report by Ralf Menzel.
1795 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1797 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1798 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1799 * tests/tools.at (autoconf: subdirectories): New test, taken from
1800 the corresponding problem report by Ralf Wildenhues in:
1801 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1803 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1804 Quote some uses of shell variables if they might suffer unexpected
1805 globbing. This doesn't fix all instances of quoting problems that
1806 I found, just the easy ones that look safe.
1807 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1808 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1809 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1810 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1811 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1812 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1813 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1814 Likewise.
1815 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1816 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1818 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1820 * bin/autoreconf.in ($help): Reword according to the manual.
1821 Suggested by Olly Betts.
1823 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1824 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1826 * bin/autoreconf.in: Pass the directory argument to
1827 `require_configure_ac'. Fix comment.
1828 * tests/torture.at (Configuring subdirectories): Expose this.
1829 Reported by Olly Betts.
1831 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1833 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1834 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1835 Automake as follows:
1837 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1838 `$configure_in' instead of `configure.in', to preserve
1839 directory component.
1841 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1843 * config/config.guess, config/config.sub, config/texinfo.tex,
1844 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1846 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1848 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1849 test for C99 conformance; (bool) 0.5 is an integer constant
1850 expression, but (bool) -0.5 is not. Problem reported by Fedor
1851 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1853 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1855 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1856 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1857 Warn about obsolete install-sh files. Remove stray sentence
1858 fragment and fix cross reference.
1859 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1860 install -d; this undoes the 2006-05-10 change.
1861 (MKDIR_P): Mark with AN_MAKEVAR.
1862 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1863 that we don't require $INSTALL to be thread-safe. Move comments
1864 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1865 of AC_PROG_INSTALL. Output a message saying that we're checking
1866 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1867 MKDIR_P instead of AC_SUBST.
1868 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1869 Special magic for MKDIR_P, too.
1870 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1871 a dnl.
1872 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1874 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1876 Sync from Automake, as follows:
1878 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1879 * config/install-sh: Initialize IFS, so field splitting isn't
1880 turned off later.
1881 * config/mkinstalldirs: Likewise.
1882 * config/missing: Remove superfluous quotes. Replace all uses of
1883 `[' by `test', for consistency, and for..
1884 * config/missing (sed_minuso, sed_output): New variables.
1885 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1886 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1887 Fixes `missing' to detect `--output' for help2man. Fixes
1888 PR automake/483. Report by Dennis J. Linse.
1889 (autom4te): Document in `missing --help'.
1891 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1893 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1894 * config/install-sh: Don't use 'path' to talk about file names,
1895 as per GNU coding standards. Close a race condition reported by Ralf
1896 Wildenhues and Stepan Kasal. There is still a race condition
1897 on hosts that predate Posix 1003.1-1992, but we can't help this.
1898 Don't mishandle weird characters like space on pre-Posix hosts.
1899 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1900 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1901 AC_PROG_MKDIR_P from AS_MKDIR_P.
1902 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1903 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1904 earlier editions are not (including Automake 1.8.3).
1905 Do not suggest mkinstalldirs for thread-safety.
1906 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1907 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1908 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1909 presence of special characters and race conditions.
1910 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
1911 in Autoconf's name space.
1913 2006-05-10 Bruno Haible <bruno@clisp.org>
1914 and Paul Eggert <eggert@cs.ucla.edu>
1916 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
1917 from Automake with minor changes.
1918 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
1920 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1922 * config/install-sh: Update to Automake CVS version, as follows:
1923 2006-04-25 Stepan Kasal <kasal@ucw.cz>
1924 * lib/install-sh: Simplify the expr implementation of dirname.
1925 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
1926 * lib/install-sh: Handle --, and diagnose unknown options.
1928 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1930 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
1931 `./autom4te' to create `./testsuite', since the `all' target
1932 will ensure its presence, but `installcheck' should not create
1933 the uninstalled wrappers.
1935 * tests/torture.at (Unusual Automake input files): Skip if we
1936 detect automake < 1.8.
1938 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1940 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
1941 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
1942 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
1943 * NEWS: Update.
1945 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1947 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
1948 munge (multiple) white space and other oddities.
1949 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
1950 single quotes in variable assignment.
1951 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
1952 and similar failures by adding multiple spaces, tabs, and other
1953 special characters.
1954 Report and different test suggested by Francesco Romani
1955 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
1957 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
1958 single quotes, we only need to search for single quotes; this
1959 both simplifies the search pattern, and makes us less
1960 susceptible to `echo' variations for arguments not containing
1961 single quotes.
1962 (_AC_ARG_VAR_VALIDATE): Likewise.
1964 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1966 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
1967 `$*' and IFS concatenation issue with traditional shells and
1968 bash-2.04. Report by Seanster@Seanster.com.
1970 2006-05-03 Bruno Haible <bruno@clisp.org>
1972 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
1973 precisely which Mac OS X versions have the od problem.
1975 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1977 * doc/autoconf.texi: Use @option systematically.
1979 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
1980 and Bruno Haible <bruno@clisp.org>
1982 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
1983 about 'od'.
1984 (Integer Overflow): Mention the special case of integer division
1985 overflow.
1987 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1989 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
1990 traditional shells like the Solaris one that do not use the
1991 first IFS character for assembling `$*'.
1992 Prompted by a related report from autoconf_bug@nro.ca.
1994 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
1995 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1997 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
1998 Mention more problems with the -e option.
2000 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2002 * NEWS: Typo.
2003 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2005 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2006 in URLs to improve DVI formatted output (requires texinfo 4.6).
2007 (System Services, Systemology, Shellology): Likewise.
2008 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2009 output.
2011 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2012 continuous text.
2013 (Runtime): Fix macro argument names to match description:
2014 `action-if-found' -> `action-if-true' and similarly.
2015 (Obsolete Macros): Likewise.
2016 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2017 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2018 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2020 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2022 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2024 * ChangeLog: Typo.
2025 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2026 DVI output.
2028 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2031 /bin/sh set unsorted output.
2032 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2033 * tests/local.at: Likewise.
2035 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2037 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2038 (Integer Overflow, Null Pointers, Buffer Overruns):
2039 (Floating Point Portability, Exiting Portably): New sections.
2040 (Writing Test Programs): Fix some langauge. Recommend exiting
2041 with status 1, not merely nonzero. Clarify exit declaration.
2042 (Run Time): Move C exit status stuff to new Exiting Portably section.
2043 (Systemology): Mention Posix and levenez. Update v7 reference.
2044 (Portable Shell): Mention the Posix shell.
2046 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2048 * bin/autoconf.as (me): Replace by as_me.
2050 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2052 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2053 since as_me isn't set yet.
2055 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2057 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2058 a few minor bugs in this area.
2060 * doc/autoconf.texi (Programming in M4sh): Comment out the
2061 documentation of AS_BASENAME, for now.
2062 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2063 (Limitations of Builtins) <basename>: Do not refer to
2064 AS_BASENAME.
2065 * bin/autoconf.as (me): Don't use AS_BASENAME.
2066 (dir): Remove the unused variable.
2067 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2068 AS_DETECT_REQUIRED. All uses changed.
2069 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2070 All uses changed.
2071 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2072 (AS_BASENAME): Use "basename --" to protect against leading "-".
2073 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2074 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2075 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2076 (_AS_DIRNAME_PREPARE): Likewise.
2077 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2078 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2079 (AS_DIRNAME): Use "dirname --".
2081 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2083 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2084 of "run time" and "run-time" changed to "runtime", for consistency.
2085 * lib/autoconf/fortran.m4: Likewise (in comment).
2086 * lib/autoconf/functions.m4: Likewise.
2087 * lib/autoconf/general.m4: Likewise.
2088 * lib/autoconf/headers.m4: Likewise.
2090 * doc/autoconf.texi (Run Time): Document the exit status situation
2091 with more accuracy and detail.
2093 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2095 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2096 Archive is not officially `GNU' any more. Update URL.
2097 (Defining Directories): Likewise
2098 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2100 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2102 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2103 newline from the `trap' code to finish `config.log'; the NetBSD
2104 /bin/sh resets the exit status after an empty command, as
2105 documented in doc/autoconf.texi.
2106 Reported by Dalibor Topic <robilad@kaffe.org>.
2108 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2110 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2111 Suggested by Bruno Haible.
2113 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2115 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2116 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2117 Instead, just list the shells that we know work.
2118 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2119 changed. Be more cautious about the _cv_ variable.
2120 * tests/tools.at (Syntax of the shell scripts): Check the
2121 _cv_ variable once, at first, to avoid an internal autoconf error
2122 when sh -n does not work.
2124 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2126 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2128 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2130 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2131 use ">&-" since we're only 99.999% sure that this is portable,
2132 and since the MinGW bug is fixed in a different way.
2133 * lib/autotest/general.m4 (AT_INIT): Likewise.
2135 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2137 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2138 before opening config.log, to avoid hitting a bug on MinGW.
2140 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2142 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2143 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2144 This works around a MinGW bug reported by Eric Paire.
2145 Make sure that all writes to the log file append to it,
2146 rather than possibly losing data.
2147 * lib/autotest/general.m4 (AT_INIT): Likewise.
2149 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2151 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2152 description.
2154 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2156 * NEWS: Update.
2158 * configure.ac (AC_INIT): Bump to 2.59d.
2160 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2162 Version 2.59c.
2164 * Makefile.maint (news-date-check): Do not require a leading `*'
2165 before the release date in NEWS.
2167 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2168 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2170 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2171 the instantiated file do not contain the string 'datarootdir'
2172 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2173 @mandir@, replace the reference '${datarootdir}' by the value.
2174 * tests/torture.at (datarootdir workaround): New test.
2175 * NEWS: Advertise this temporary fixup.
2176 Based on a patch by Bruno Haible, reported and analyzed by
2177 Paul Eggert and Noah Misch.
2179 2006-04-12 Eric Blake <ebb9@byu.net>
2181 * tests/autotest.at (Debugging a failed test): Fix comment.
2183 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2185 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2186 all the changes since 2006-04-07.
2188 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2190 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2191 succeeded, but `ln -s file dir' failed, take care to remove the
2192 leftover target before the next test, to prevent its spurious
2193 failure; also make sure `ln file dir' works before selecting it.
2194 Thanks to Keith Marshall for pointing this out.
2195 * THANKS: Update.
2197 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2198 assignments in `at_debug_args', so that we put them correctly
2199 in the `run' script.
2200 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2201 Reported by Eric Blake.
2203 2006-04-11 Eric Blake <ebb9@byu.net>
2205 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2206 top-level tests after micro-suite has been run. Used in...
2207 (Debugging a successful test, Debugging script and environment),
2208 (Debugging a failed test): ...these new tests. The first of these
2209 is fixed by...
2210 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2211 macro, split out from...
2212 (AT_INIT): ...here, so that using -d also generates a run script.
2213 Document that -d inhibits top-level logging.
2214 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2215 inhibits top-level logging; debug scripts are created.
2217 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2218 check.
2219 * tests/autotest.at (Empty test, Empty check): New test to check it.
2221 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2222 from gcc.
2224 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2226 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2227 the files if a problem appears. Make the empty *.at files
2228 read-only, too. Proposed by Ralf Wildenhues.
2230 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2232 * config/Makefile.am: Add comment to force updated Makefile.in.
2234 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2235 space only patch to this file, this patch causes the Makefile.in
2236 files that include freeze.mk to be updated, and thus have a
2237 newer time stamp again, which in turn makes a pristine CVS
2238 checkout have correct time stamps.
2240 * Makefile.maint (cvs-sv): New macro, to be used..
2241 (config.guess-url_prefix, config.sub-url_prefix)
2242 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2243 point to CVS text checkout of Gnulib files.
2244 (copyright-check): Bump current year.
2245 (announcement): Do not hard-wire `./announce-gen'.
2246 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2247 correctly.
2248 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2249 `chmod +x'.
2250 (wget_files): Update config.guess, config.sub, texinfo.tex by
2251 `wget-update', now that their URLs work again.
2253 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2255 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2256 Problem noted by Paul D. Smith.
2258 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2260 * doc/autoconf.texi: Remove unused words from word list.
2261 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2262 .x-sc_trailing_space: New files.
2264 * doc/standards.texi: Sync from gnulib.
2266 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2267 `LIBOBJDIR' as experimental.
2269 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2270 with a target directory; it's internally implemented as `cp'
2271 anyway, but since Autoconf advertises the possibility to use
2272 a target directory when LN_S is `ln -s', we need to find out.
2273 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2274 analyzed by Keith Marshall <keith.marshall@total.com>.
2276 * THANKS: Update.
2278 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2280 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2281 confdefs.h as-is. In general, if it has backslash-newline or the
2282 like, then it doesn't work either to sort or to remove empty
2283 lines.

2294 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2296 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2297 apostrophe within a single-quoted string, as this is the usual
2298 tradition and is easier to read than '"'"'. Don't rely on the
2299 shell treating "$/" like '$/'. Use a more-consistent indenting
2300 style for the trap.
2302 2006-04-09 Eric Blake <ebb9@byu.net>
2304 * tests/autotest.at (Backquote command substitution),
2305 (Multiline backquote command substitution): Remove mistaken
2306 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2307 applied...
2308 (Parenthetical command substitution, Multiline parenthetical
2309 command substitution): here.
2311 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

2345 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2346 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2347 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.

2386 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2388 Revert the patch from 2006-04-01 and only improve
2389 _AS_DETECT_BETTER_SHELL:
2391 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2392 skip nonexistent directories.
2393 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2394 only shell candidates which exist.
2395 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2396 * lib/autotest/general.m4 (AT_INIT): No need to give three
2397 parameters to _AS_PATH_WALK.
2399 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2400 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2402 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2403 distinguish m4sugar macros.
2404 * tests/tools.at (autoupdating with aclocal and m4_include):
2405 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2406 test case by Noah Misch <noah@cs.caltech.edu>.
2408 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2410 Revert my change from 2006-03-17, in other words:
2411 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2412 and DUALCASE=1.
2413 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2414 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2415 it is set.
2417 2006-04-07 Eric Blake <ebb9@byu.net>
2419 * doc/autoconf.texi (Programming in M4sh): Document that
2420 AS_MKDIR_P exits the script on failure.
2421 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2423 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2425 * config/elisp-comp, config/install-sh, config/mdate-sh,
2426 config/missing, config/mkinstalldirs: Sync from Automake.

2442 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2444 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2445 whether `set' quotes correctly: redirect stderr of the tested
2446 `set', and use a subshell, for Ultrix; use `sed' instead of
2447 `grep' for zsh `set' which may write binary output; match only
2448 at the beginning of a line, to avoid false positives.
2449 In order to avoid false positives by unrelated variables with
2450 multiline content, put the dump algorithm in a subshell and
2451 unset all variables containing newlines (except some which are
2452 special to the shell). Warn about cache variables that are
2453 unset.
2455 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2457 * config/config.guess, config/config.sub, config/texinfo.tex:

2466 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2467 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2468 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2469 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2471 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2472 shell issue with double-quoted command substitutions of native
2473 commands.
2474 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2475 Marshall.
2477 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

2494 * tests/Makefile.am (maintainer-check-posix):
2495 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2497 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2498 ac_config_<foo>s again, sometimes normalized, sometimes not.
2499 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2500 (AC_CONFIG_COMMANDS): Do not do so here.
2501 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2502 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2503 2005-07-25 rewrite. Noticed by Noah Misch.
2505 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2506 _AC_PRESERVE_HELP_ORDER, ...
2507 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2509 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2510 inside m4_expand_once; it is redundant.
2512 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2513 for --help from Cygnus `configure.'
2515 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

2522 * lib/autoconf/status.m4: Replace <space>''<tab> with
2523 <tab><space> where this makes sense.
2525 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)

2528 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2529 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2530 * doc/autoconf.texi (Help Formatting): New node.
2531 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2533 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2535 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
2536 lib/autoconf/specific.m4, lib/autoconf/status.m4,
2537 lib/autoconf/types.m4, lib/autotest/general.m4,

2539 remove some SPACE before TAB, or add quoting ('' or @&t@).
2541 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
2543 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
2545 2006-04-05 Eric Blake <ebb9@byu.net>
2547 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2548 empty test suite works.
2549 * tests/autotest.at (Empty test suite): Remove xfail.
2551 2006-04-05 Noah Misch <noah@cs.caltech.edu>

2554 TAGS to ac_config_<foo>s.
2555 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2556 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2557 normalizing it, consistent it with previous releases.
2558 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
2560 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2562 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
2563 Use simplified args that Eric Blake originally suggested.
2565 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
2567 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
2568 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2569 Use 'comm' rather than N instances of grep; this also fixes a bug
2570 whereby substrings were incorrectly matched, causing us to not
2571 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2572 (exclude_list): Exclude empty macros.
2573 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

2584 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
2585 a subdirectory subject to Cygnus `configure'.
2586 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
2588 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
2589 report request when we have no AC_PACKAGE_BUGREPORT.
2591 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2593 * THANKS: Update.

2623 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
2624 to log, point to testsuite output tree.
2626 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
2628 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

2654 Clean up _AC_COMPILER_EXEEXT* macros.
2656 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2657 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2658 ac_file to the name of the default output file and call
2659 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2660 initial `rm' of the candidate files...
2661 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2662 the same list in subsequent `rm' calls, and for the temporary
2663 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2664 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2665 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2666 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2667 no longer needed) by libtool. Make it a cache check.
2668 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2669 copied here by mistake.
2670 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2671 _AC_COMPILER_EXEEXT.
2672 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call

3445 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3446 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3447 by the function rather than ignoring it.
3448 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3449 comparing its address. Intel's interprocedural optimization was
3450 outsmarting the old heuristic. Problem reported by

3468 Stepan Kasal <kasal@ucw.cz>
3470 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3471 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3472 make its content writable before removing it. Remove an errorneous
3473 comment from the end, where the logs of the failed tests are copied
3474 to the main log file.
3476 2005-09-27 Stepan Kasal <kasal@ucw.cz>

3483 problems if the testsuite were running too fast.
3485 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3487 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

3499 suggested by Ben Elliston. Handle weird characters correctly.
3501 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3503 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3504 calls, so that the final expansion of this macro is shorter.
3505 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3506 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3507 the cleanup there. Use AS_VAR_* macros, to be more general.
3508 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3510 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3512 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

3527 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):

3530 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3532 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3533 in the example. Reported by Bruno Haible.
3534 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3535 "if $undefined_var;" succeeds with my shell.
3537 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3538 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3539 but change the m4_divert_text to m4_divert_once.

3549 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3550 some evil values and relying on the fact that $* concatenates the
3551 parameters by the first character from IFS.
3553 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3554 Stepan Kasal <kasal@ucw.cz>
3556 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3557 first header appears, define AH_HEADER.
3558 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3559 Update limitations about when to call AC_CONFIG_HEADERS.
3560 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3561 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3562 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3563 ``Configuration Actions''; fix their index entries.
3565 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3566 options correctly. Process N-M as M-N if M is smaller than N.
3567 Process ranges correctly so that N-N will run only N.
3568 Sort and uniquify the tests that will be run. If there is more
3569 than one test, reinsert the banners for the tests.

3575 before passing the macro name to AH_TEMPLATE.
3577 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3578 now opens log after option processing; in particular, --version
3579 and --help do not touch config.log.

3596 Prepend to LIBS, not append, in examples.
3598 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3600 When building in place, set srcdir="."; suggested by Tim Van Holder.
3602 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3603 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3604 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3605 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

3617 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3619 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3620 add "2>&1"; gzip 1.2.4 prints help on stderr.
3622 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3624 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3625 was pushdef'ed twice while popped only once. Push it only once.

3635 * Makefile.maint: Update from Bison.
3637 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3638 "<tab>" in comment, so that the point is understandable.
3640 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3642 Rewrite substantial part of lib/autoconf/status.m4.
3643 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3644 and CONFIG_COMMANDS are not processed in four separate loops.
3645 Instead, there is one main loop. This alows that the common code
3646 is expanded only once, thus config.status (and configure) is smaller.
3648 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3649 the AC_LIST_FILES and cousins macros are no longer used.
3651 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3652 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3653 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3654 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3655 contain the initialization, nor the for loop, nor the associated
3656 commands; all these go to ...
3657 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3658 _AC_OUTPUT_CONFIG_STATUS.
3659 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3660 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3661 (_AC_OUTPUT_FILE): The creation of the sed script ...
3662 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3663 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3664 _AC_OUTPUT_MAIN_LOOP.
3665 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3666 _AC_CONFIG_COMMANDS): Use ...
3667 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3668 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3669 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3670 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3671 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3672 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3673 ... new macros.
3674 (_AC_CONFIG_UNIQUE): Update.
3675 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3676 Replaced by this ...
3677 (_AC_LIST_TAGS): ... new common macro.
3678 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3679 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3680 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3681 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3682 this didn't belong to the `config commands' section.
3683 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3684 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3685 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3686 to the `config commands' section either.
3687 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3688 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3690 ... and many changes to the comments nearby.
3692 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3693 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3694 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3695 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3696 (#define header templates): The comment at the top of the generated
3697 header now includes the name(s) of the source file(s).
3699 Several unrelated small changes:
3701 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3702 parameter to AC_DIAGNOSE.
3703 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3704 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3705 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3706 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3707 with AU::AC_OUTPUT.
3708 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3709 in AC_OUTPUT doesn't double-quote it either.
3710 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3711 parameters.
3713 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3715 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3716 versions of Portland Group compiler produce single- and double-quoted
3717 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3718 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3720 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3722 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3723 This is a corrected version of yesterday's patch.
3725 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3727 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3728 path, too; insert a "===" to emphasize the line.

3731 ac_cv_build_alias to ac_build_alias.
3732 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3734 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3735 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3736 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3737 (AC_ARG_VAR): ... here.
3738 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3739 target_alias.
3741 Keep a list of all precious variables and process them with one simple
3742 for loop, instead of expanding all commands, or, OTOH, complicated
3743 processing of output of "set".
3744 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3745 variable names in new macro...
3746 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3747 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3748 a loop to assign all ac_env_* and ac_cv_env_* variables.
3749 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3750 to INIT_PREPARE.
3751 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3752 its value to shell variable ac_precious_vars and call
3753 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3754 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3755 _AC_ARG_VAR_VALIDATE.
3757 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3758 and the AC_SUBSTs ...
3759 (AC_INIT): ... here.
3761 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3762 the ac_subst_files section in config.log.
3764 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

3773 Fix problems reported by Nicolas Joly.
3774 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3775 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3776 They are generated by the Tru64 v5.1B shell.
3778 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3780 Fix my changes from 2005-07-01; reported by Noah Misch.
3781 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3782 description, the macro now accepts only a single tag.
3783 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3785 Fix cases when the varsions of Autoconf and Autotest don't match.
3786 Reported by Noah Misch.

3788 at_top_builddir, for compatibility with older autotest.
3789 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3790 is not set, use at_top_builddir, for compatibility with older
3791 versions of autoconf.
3793 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3795 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3796 Problem reported by Patrick Welche.
3798 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3800 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3801 sed substitution command, so that we allow | in program prefixes
3802 and program suffixes. (& is a problem anyway; we're not fixing
3803 that here.)
3804 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3805 configure_input, top_builddir, srcdir, etc.
3806 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3807 PATH_SEPARATOR in AUTOTEST_PATH.
3809 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3811 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
3812 for loop over config.site files using `set', to allow
3813 directory names containing IFS characters.

3817 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3818 directories with weird names. Apparently some people like living

3837 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
3839 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3840 document to output the default config_* lists to config.status.
3841 Don't recognize option --file, if the functionality is not there.
3842 Likewise for --header; moreover, recognize --he and --h as shortcuts
3843 for --help in that case.
3845 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3846 matches the order of execution. No code changed.

3867 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3868 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3869 (AC_SUBST): Call it.
3870 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3871 the directory specific variables; but don't call it for configure_input.
3873 2005-06-28 Derek Price <derek@ximbiot.com>
3875 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3876 addition.
3878 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3880 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3881 directory have inherent problems with special characters like spaces,
3882 due to limitations in Make syntax. Problem reported by Alexandre
3883 Duret-Lutz.
3884 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

3897 from Justace Clutter.
3898 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
3899 variable into diagnostic. Make the diagnostic an error, not a warning,
3900 because we really don't support spaces and suchlike in dir names.
3901 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3902 Don't worry about backslashes in srcdir; it can't happen now.
3903 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
3904 Simplify ac_optarg handling.
3905 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

3913 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
3915 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
3916 that '\|' is not allowed in BREs; recommend using newline separated
3917 list of patterns instead of multiple -e options.
3919 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
3921 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.
3923 2005-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3927 2005-06-21 Stepan Kasal <kasal@ucw.cz>
3929 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
3930 b, t, r, w commands require single space, while : cannot have any.
3931 (Special Shell Variables): Fix sed code this in the example.
3932 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
3933 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
3935 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
3936 expand to the empty list. Don't use two pairs of m4_changequote,
3937 it's not necessary.
3939 2005-06-20 Derek Price <derek@ximbiot.com>
3941 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
3943 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
3945 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
3946 * doc/autoconf.texi:
3947 Don't mention Solaris versions so much, if a
3948 problem is common to all extant versions of Solaris. Say "SunOS
3949 4" instead of "SunOS" for SunOS 4.
3950 (awk): Mention more of the limitations of traditional Awk.
3951 (cat): Don't talk about cat -v.
3953 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
3955 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
3956 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

3958 to be compatible with glibc strverscmp.
3959 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
3961 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
3962 on Mac OS X 10.4 reported by Peter O'Gorman in:
3963 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
3964 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
3965 Use shell builtins rather than 'expr', to work around expr bug.
3967 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
3969 * doc/autoconf.texi: "filesystem" -> "file system".
3970 "behaviour" -> "behavior".
3971 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
3972 * lib/autoconf/general.m4: Omit blank after ":" sed command,
3973 as per POSIX.

3983 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
3984 quotes and backslashes. Patch from Derek Price.

3993 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
3994 -u, since it outputs chatter if the input files are the same.
3995 Problem reported by Ralf Menzel.
3997 2005-06-08 Derek Price <derek@ximbiot.com>
3999 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4000 renaming them since they are about to be redefined anyhow.
4002 2005-06-08 Derek Price <derek@ximbiot.com>
4004 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4005 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4006 Move m4_undefine to alphabetical order.
4008 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4010 * README: Recommend GNU M4 1.4.3 or later.
4011 * doc/autoconf.texi (Introduction): Likewise.
4012 Reword to avoid some formatting glitches.
4013 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4014 Clarify explanation of HP compiler bug.
4015 Redo example output tp match current CVS snapshot.
4016 Use @example.org in email addresses when the examples
4017 might get inadvertently cut-and-pasted into user code.
4018 Remove example of autom4te usage that doesn't seem to work now.
4019 Use modern AC_INIT (except when the example is meant to be
4020 shown with Autoconf 2.13).
4021 Update ksh info for Solaris 9 and later.
4022 KB -> kB.
4023 Modernize description of Automake versions a bit.
4024 Don't claim a future version of Autoconf is near.

4030 follows its own advice about quoting better.
4031 Reword to avoid some formatting glitches.
4032 * doc/installt.exi: Reword to avoid some formatting glitches.
4034 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4035 Tru64 ksh pattern matching bug. Reported against Libtool by
4036 Albert Chin <libtool@mlists.thewrittenword.com> and
4037 Nicolas Joly <njoly@pasteur.fr>.
4039 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4041 m4_cdr of one-member list was [[]] (one-member list containing an
4042 empty string) instead of [] (an empty list. Callers were skewed to
4043 match this misbehaviour. As a consequence of this:
4044 - m4_foreach([x], [], [foo]) expanded to `foo', while
4045 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4046 This bug has been fixed:
4048 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4049 expand to an empty string; print error msg if called without
4050 an argument list.
4051 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4052 misbehaviour; handle [] and [[]] correctly.
4054 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4056 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
4057 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
4058 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4060 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4062 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4063 swallow records with more than 99 fields.
4064 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4065 parse the long line.
4067 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4069 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4070 swallow literals longer than 399. Reported by Ralf Wildenhues.
4071 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4072 to workaround this limitation.
4074 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4076 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4077 to gfortran, and make these the first two compiler names
4078 checked (following the general autoconf preference for gcc).
4080 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4082 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4083 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4084 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4086 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4088 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4089 expression of unbounded size when processing the --list
4090 option. This runs afoul of a limit of 399 bytes per regular
4091 expression on AIX. Problem reported by Ralf Wildenhues.
4093 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4095 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4096 * doc/autoconf.texi (Particular Headers): Reword example
4097 for multiline stdbool replacement.
4098 (Setting Output Variables): Reword text a bit. Don't
4099 give all the details about |#_!!_#|.
4100 Reword description of line replacement.
4102 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4104 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4105 now contain newlines, and substituted files must be referenced on
4106 a line alone; the sed scripts to substitute them are now very
4107 different.
4108 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4109 commands can be put in a sed script portably.
4110 * doc/autoconf.texi (Setting Output Variables): Document above
4111 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4112 use of multiline substitution.
4113 * tests/torture.at: No longer expect substitution of newline to fail.
4115 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
4117 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
4118 From Ralf Menzel (trivial change).
4120 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
4122 * tests/local.at: Don't attempt to check for negated character
4123 classes in shell scripts. The test was too brittle.
4125 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4127 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4128 * doc/autoconf.texi (Limitations of Builtins): Document this
4129 limitation.
4131 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4133 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4134 common code; used in many places in the tree.
4135 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4136 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4138 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4140 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4141 messages when ac_unique_file is not found.
4142 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4143 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4144 commands, for consistency with AC_MSG_ERROR and such.
4146 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4148 * bin/Makefile.am: Merge the two rules for creating scripts.
4150 2005-05-23 Stepan Kasal <kasal@ucw.cz>
4152 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
4153 obsolete; it was never documented.
4154 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
4156 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4158 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4159 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4160 (ac_top_builddir): ... this ...
4161 (ac_top_build_prefix): ... to this; the old name is also kept, for
4162 backward compatibility.
4163 (ac_top_builddir_sub): New variable, without the trailing slash,
4164 always nonempty.
4165 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4166 * doc/autoconf.texi (Configuration Actions): Rename
4167 ac_top_builddir to ac_top_build_prefix.
4168 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4169 at_top_builddir to at_top_build_prefix.
4170 * lib/autotest/general.m4 (AT_INIT): Likewise.
4172 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4174 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4175 of confdefs.h .
4177 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4179 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4180 argument to m4_foreach. I guess it was necessary in the past,
4181 but I think it's a no-op now.
4183 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4185 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4186 ``cat <<_ACEOF'' commands to one.
4187 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4188 * lib/autoconf/status.m4: On various places, use expr instead of
4189 ``echo|sed.''
4190 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4191 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4192 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4193 a range.
4194 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4195 the wrong patterns between ``case'' and ``esac.'' The previous
4196 code had false positives.
4198 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4200 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4201 as on 2005-05-02.
4202 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4203 Mention LIBOBJDIR.

4243 2005-05-13 Stepan Kasal <kasal@ucw.cz>
4245 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
4246 check.
4247 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4248 enough arguments, similarly as in m4_bpatsubsts.
4250 2005-05-12 Stepan Kasal <kasal@ucw.cz>
4252 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
4253 of absolute paths.
4255 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4257 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4258 for absolute directory names in one loop.
4259 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4260 abbreviations of --version and --debug.
4262 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4264 * doc/autoconf.texi (Autoconf Language): Be more precise about
4265 quoting rules. Problems noted by Stepan Kasal.
4266 Also, throughout this document, be more careful about white space.
4267 "blank", "white space", and "space" all have different meanings
4268 and we should be careful to say what we mean.
4270 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4272 Fix C++ related problems reported by Werner Lemberg.
4273 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4274 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4275 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4276 avoid problems with C++ and throw.
4277 * tests/compile.at: .cpp, not .cc.
4279 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4281 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4283 * doc/autoconf.texi (Generic Functions): Typos.
4285 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4287 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4288 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4289 set by latest automake.
4291 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4293 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4294 outputs 0 on GNU/Linux these days.
4296 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4298 * doc/autoconf.texi (Autoconf Language): Add more description
4299 about quoting heuristics.
4300 (Limitations of Builtins): Describe "set -" problems.
4302 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4304 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4305 not newline.
4307 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4308 by AC_DEFINE; it was a mistake.
4309 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4311 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4313 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4315 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4317 * doc/autoconf.texi (External Software): Quadrigraphs are not
4318 processed correctly in AS_HELP_STRING; avoid this in the examples.
4319 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4320 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4321 comment and reduce m4_default([foo], []) to [foo].
4322 (m4_strip): Update the explanation.
4324 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4326 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4327 Remove core.conftest.* too; it's generated by Tru64 5.1.
4328 Problem reported by Jennis Pruett.
4329 * lib/autoconf/functions.m4
4330 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4331 Don't bother to remove core files; AC_RUN_IFELSE should do that
4332 for you.
4334 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4336 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
4338 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
4340 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
4341 Report from Horst Wente.
4343 2005-04-15 Stepan Kasal <kasal@ucw.cz>
4345 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
4346 the comment.
4348 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
4350 * doc/autoconf.texi (External Software, Package Options): Add
4351 examples showing how to implement --with-* and --enable-* options.
4353 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4355 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4356 as well as configure.in. Problem reported by Gregorio Guidi.
4358 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4360 * doc/autoconf.texi (Particular Functions): Use gnulib's current
4361 pattern for alloca snippet.
4363 2005-04-04 Stepan Kasal <kasal@ucw.cz>
4365 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.

4371 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4373 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4374 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4376 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4378 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4379 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4380 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4381 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4382 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4384 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4386 * NEWS: The configure command now warns you if you attempt to use
4387 a directory whose name contains a special character like space,
4388 newline, or "\".
4389 * doc/autoconf.texi (Installation Directory Variables): Allow
4390 "," in file names. Do not use \@; it's not a portable regexp.
4391 * bin/Makefile.am (edit): Likewise.
4392 * lib/Makefile.am (edit): Likewise.
4393 * tests/Makefile.am (edit): Likewise.
4394 * tests/semantics.at: Likewise.
4395 * tests/torture.at: Likewise.
4396 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4397 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4398 * doc/autoconf.texi (File System Conventions): Warn about
4399 unportable file names.
4400 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4401 (AC_INIT): Use it.
4402 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4403 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4404 ac_pwd, and quote srcdir.
4405 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4407 * doc/autoconf.texi: Fix some systematic formatting problems.
4408 ".)" needs a following @: if not at the end of a sentence, and
4409 similarly for "!)". "etc." should be preceded by a comma.
4410 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4412 2005-03-22 Bruno Haible <bruno@clisp.org>
4414 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4415 argument is often called 'build-aux'.
4417 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4419 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4420 macro AC_TRY_LINK is obsolete.
4421 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4422 `AC_CONFIG_FILES'.
4424 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4426 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4427 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4428 from a Common Lisp's `cl'.
4429 (AC_PROG_CXX): Behave according to the documentation: don't
4430 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4431 make the variable CCC precious; use `cl.exe', not `cl'.
4433 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4434 Alexandre Duret-Lutz <adl@gnu.org>
4436 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4437 /dev/null, as "configure" shouldn't read stdin, and this insulates
4438 us from problems (e.g., when testing for "cl"). Also, do this
4439 redirection before invoking "hostname" or "uname", and keep the
4440 original input stream available via...
4441 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4442 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4443 bother with "</dev/null" since it's now done at the top of
4444 'configure'.
4445 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4446 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4447 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4448 * doc/autoconf.texi (File Descriptor Macros): New section.
4449 (Printing Messages): Mention it.
4450 * tests/base.at (Input/Output): New test.
4452 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4454 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4455 newline if neither \c nor -n work, as that would output two
4456 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4458 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4460 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4461 This causes that any required macros inside will get before the if.
4462 * doc/autoconf.texi (autom4te.cache): A typo.
4464 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4466 Undo previous change, except keep the change to
4467 lib/autoconf/programs.m4 that replaced grep with shell
4468 pattern-matching. This is because net-snmp configure reads stdin.
4469 Reported by Noah Misch.
4471 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4473 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4474 from /dev/null, as "configure" shouldn't read stdin, and this
4475 insulates us from problems (e.g., when testing for "cl").
4476 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4477 before invoking "hostname" or "uname".
4478 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4479 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4480 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4481 "</dev/null" since it's now done at the top of 'configure'.
4482 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4483 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4484 Also, replace grep with shell pattern-matching, to save a process.
4486 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4488 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4489 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4490 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4491 compiler.
4493 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4495 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4496 grep -q isn't portable. Improve grep -s explanation.
4497 Problem reported by Dan Manthey.
4499 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4501 * doc/autoconf.texi (Special Shell Variables): Clarify
4502 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4504 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4506 * doc/autoconf.texi: Use @acronym for DJGPP.
4507 Fix some @code's that should have been @env's, and vice versa.
4508 Sort environment variable names.
4509 Mention that shells no longer inherit IFS.
4510 Don't recommend PATH_SEPARATOR=';' so strongly.
4511 Mention that $RANDOM might expand to the empty string.
4512 "symlink" and "soft link" -> "symbolic link".
4513 Improve mktemp description (reported by Bruno Haible).
4515 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4517 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.

4589 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4591 Try not to generated lines of unlimited length, as POSIX places a
4592 2047-byte limit on line length of portable text files.

4652 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4653 Update the long comment explaining it.
4655 m4_require no longer writes an ``is required by'' line to the
4656 execution stack. It contains only one bit of non-redundant
4657 information: that the macro was required, not called. And even
4658 this bit is useless in most situations: have you ever met a macro
4659 which both calls and requires the same macro?
4661 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4662 (_m4_defun_pro_outer): ... only via this macro, for the outermost

4669 (_m4_require_call): Use it.
4670 * tests/m4sugar.at (m4_require): Expect output without the
4671 ``is required by'' messages.
4673 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4675 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4676 rather than x for expr.

4679 this is safe.

4707 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4709 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4710 Warn about newline stripping in `` and $(). Update Solaris
4711 version to 9.
4712 (Limitations of Builtins): Use expr "X...", not expr "x...", as

4715 stripping.
4717 2005-01-19 Stepan Kasal <kasal@ucw.cz>

4739 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4741 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

4764 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4765 otherwise.
4766 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4767 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4768 stored in _m4_divert_diversion or _m4_divert_dump.
4769 (m4_divert_pop): When the parameter is given, compare the symbolic
4770 name with the last diversion pushed on the stack. Previously, the
4771 current diversion was compared with the numeric value of the
4772 diversion given as the parameter.
4773 (m4_require): If the macro hasn't been expanded yet, call ...
4774 (_m4_require_call): this new macro.

4807 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

4860 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
4861 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

4988 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
4989 Don't depend on .x file explicitly, since "make" does that for us.
4990 Suggested by Stepan Kasal.
4992 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
4993 Add *.tmp.

5053 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
5055 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
5056 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5057 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5058 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
5060 2004-12-07 Stepan Kasal <kasal@ucw.cz>
5062 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

5077 with exactly one parameter.
5079 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5081 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5082 "char c = '\200';" rather than "char c = 0x80;" as the
5083 latter doesn't conform to the strict C standard due to
5084 overflow on signed char hosts.
5086 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5087 to -qlanglvl=ansi. We don't want to disable extensions.

5145 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5147 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5148 the $1_found variable, don't test whether the file is executable;
5149 Both things are checked ...
5150 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5151 the former ``test -f''.
5152 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
5154 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

5187 Problem reported by Stepan Kasal.
5189 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5191 Fix problems reported by Andreas Buening in:
5192 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html

5194 in test makefile.
5195 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

5198 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5200 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5201 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5202 (trivial change). Problem and patch reported by Andrew Church in:
5203 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5205 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5207 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

5210 Also, fix some minor spacing and punctuation bugs.

5232 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5233 texinfo.tex for now (done by hand now).
5234 * Makefile.maint (wget_files, cvs_files):
5235 Remove ansi2knr.c; nobody uses it.
5236 (ansi2knr.c-url_prefix): Remove.
5237 (cvs-update): Fix test for failure. I don't know why it ever
5238 worked...
5240 * doc/autoconf.texi: Update URLs, some of which went stale.
5241 Use @uref rather than @href.
5243 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5244 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5246 * config/config.guess, config/config.sub, config/elisp-comp,
5247 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5248 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5250 * NEWS, TODO, configure.ac, bin/autoscan.in,
5251 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5252 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5256 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5257 tests/tools.at, tests/torture.at:
5258 Use "file name" rather than "filename" or "path",
5259 to be consistent with the terminology of the GNU coding standards.
5261 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5263 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5264 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5265 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5266 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5268 More fixes to support spaces in the name of the build directory.
5269 This isn't a complete fix but it's an improvement.
5271 * bin/autoconf.as (autom4te_options): New var.
5272 Use it instead of appending to AUTOM4TE, so that we can allow
5273 spaces in the build directory's absolute name.
5274 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5275 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

5280 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>
5282 * lib/autoconf/general.m4 (_AC_INIT_HELP): Quote $ac_popdir uses.
5283 From Ralf Corsepius in:
5284 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
5286 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5288 * doc/autoconf.texi (Function Portability): Document isinf and
5289 and isnan. From a suggestion by Kevin Ryde.
5291 * lib/Autom4te/General.pm (END): Return correct exit status even
5292 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5294 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5296 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5297 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5298 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5300 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5302 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5303 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5304 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5305 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5306 * lib/autom4te.in (Automake-preselections): Preselect
5307 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5309 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5311 * lib/autom4te.in (Automake-preselections): Preselect
5312 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5313 trace them.
5315 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5317 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5318 Tru64.
5319 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5320 Document problem with "`""`" in pdksh POSIX mode.
5322 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5324 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5325 with pdksh, too. Problem reported by Patrick Welche via
5326 Gary V. Vaughan.
5327 * doc/autoconf.texi (Shellology): Note that set -o posix is
5328 useful for pkdsh, too.
5330 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5332 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5333 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5334 Don't fail if ENV or BASH_ENV is readonly.
5335 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5336 etc. are read only. Problem reported by Ludovic Courtes.
5338 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5340 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5341 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5342 (trivial change)
5344 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5346 * doc/autoconf.texi (File System Conventions): Warn about
5347 names like "aux". Problem reported by Eric Blake.
5349 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5350 by zero instead of array size, so that we can use any arithmetic
5351 constant expression (instead of requiring an integer constant
5352 expression). This allows us to test expressions like DBL_MAX <
5353 LDBL_MAX, which didn't conform to the C standard using the old
5354 method.
5355 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5356 now that we can do floating-point tests at compile time.
5358 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5360 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5361 and LDBL_EPSILON, as the resulting expression isn't an
5362 integer constant expression and violates the C standard.
5363 Problem reported by Nelson H. F. Beebe. Also, check
5364 for "L" suffix, and check that long double doesn't have
5365 worse range or precision than double, that mixed-mode
5366 arithmetic doesn't generate a diagnostic, that double
5367 constants fit in long double.
5369 2004-06-03 Kevin Ryde <user42@zip.com.au>
5371 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5372 malloc(0) and realloc(NULL,size).
5374 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5375 Bob Proulx.
5377 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5379 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5380 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5381 by Jim Meyering.
5383 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5385 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5386 can be rewritten using if-then-else. Suggested by Bruno Haible.
5388 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5390 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5391 Problem reported by Stepan Kasal.
5393 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5395 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5396 change). Patch reported by Ralf Wildenhues in
5397 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5399 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5400 function F exists if the compiler and linker let you compile an
5401 expression like (F != 0). Recent versions of GCC optimize away
5402 the reference to F in that case, since every function address must
5403 be nonzero, so the link succeeds even if F does not exist.
5404 Problem reported by Manu in
5405 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5407 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5408 "Unix". Many uses changed.
5409 (Limitations of Builtins): Explain better why the ! command isn't
5410 portable.
5412 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5414 * lib/autom4te.in (Automake-preselections): Preselect
5415 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5417 2004-05-19 Kevin Ryde <user42@zip.com.au>
5419 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5420 referencing AC_FUNC_STRERROR_R.
5422 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5423 note pessimistic assumption when cross compiling.
5425 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5427 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5428 (until 2004) invoked subcommands with sh -e, contra POSIX.
5429 Reported by Kevin Ryde.
5431 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5433 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5434 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5435 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5436 `test -f " /usr/bin/grep"', which _always_ failed.
5437 (AC_PROG_SED): Ditto bogus PATH fix.
5438 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5439 requires that grep correctly supports _multiple_ `-e' options, rather
5440 than stating only that grep should accept `-e'.
5442 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5444 Port to C99, which requires that 'exit' be declared.
5446 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5447 to ensure that stdlib.h is included.
5448 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5449 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5450 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5451 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5452 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5453 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5454 when using 'exit' in a test; C99 requires that 'exit' be declared.
5456 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5458 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5459 now prefers 'grep' implementations that accept -e.
5460 (Limitations of Usual Tools): Describe problems of traditional
5461 egrep and fgrep with long input lines, and of traditional grep
5462 with -e.
5463 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5464 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5465 All callers changed. Append /usr/xpg4/bin to the PATH, for
5466 Solaris.
5467 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5468 the user with complaints about multiple -e options.
5469 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5470 Define it with AC_PROG_GREP.
5471 * configure.ac (AC_PROG_GREP): Add.
5472 * lib/freeze.mk (GREP): New macro.
5474 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5476 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5477 a possible candidate only after all others fail, rather than
5478 consulting it first. This improves backward compatibility by
5479 better reflecting the way shell selection occurred in previous
5480 versions of Autoconf, and should help to avoid triggering latent
5481 problems in other packages, such as the one in Automake where zsh
5482 is not handled robustly:
5483 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5484 Although it is not Autoconf's responsibility to work around
5485 problems in Automake, it nevertheless makes sense to avoid
5486 introducing unnecessary incompatibilites.
5488 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5489 Gary V. Vaughan <gary@gnu.org>
5491 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5492 how deeply nested we are when a suitable tool is found, set the
5493 ac_path_TOOL_found flag.
5494 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5495 nested we are in this macro. Break out of all 3 nested loops if
5496 ac_path_TOOL_found is set.
5498 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5500 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5501 of the _AS_PATH_WALK loop too if GNU flavor is found.
5503 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5505 * doc/autoconf.texi (Limitations of Make): Update documentation
5506 for `$<'. New entry `Long lines', based on a report from Simon
5507 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5508 paragraph about DJGPP, based on a mail from Richard Dawe.
5510 2004-04-20 Paul Eggert <eggert@twinsun.com>
5512 * tests/c.at (C keywords): Don't assume that GCC supports
5513 "restrict" and "inline", as sufficiently-old GCC versions do not
5514 (also, GCC configured to be in pedantic C89 mode does not).
5515 Problem reported by Sumit Pandya in:
5516 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5518 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5519 consider -g to work if it generates warnings when plain compiles
5520 don't. Problem reported by Braden McDaniel in:
5521 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5523 * doc/autoconf.texi (Slashes): New section, to document a problem
5524 reported by Jim Meyering in:
5525 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5527 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5528 linker output files before linking, to work around IRIX 6 linker bug.
5529 Problem reported by Rainer Orth in:
5530 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5532 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5534 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5535 best tool so far counter rely on the tool path variable name to
5536 avoid checks for one tool being affected by the results of running
5537 the length check on a previous tool.
5539 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5540 match expression argument, as different greps have different
5541 regular expression flavours.
5542 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5543 literals.
5544 (AC_PROG_EGREP): Pass 'EGREP$'.
5545 (AC_PROG_GREP): Pass 'GREP$'.
5547 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5549 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5550 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5552 2004-03-29 Paul Eggert <eggert@twinsun.com>
5554 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5555 Types, Specific Compiler Characteristics, System Services,
5556 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5557 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5558 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5559 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5560 Likewise.
5561 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5562 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5563 AC_TYPE_OFF_T): Likewise.
5564 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5565 Likewise.
5567 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5568 pacify libtool 1.5.2. Fix quoting problems in sed command.
5570 2004-03-28 Paul Eggert <eggert@twinsun.com>
5572 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5573 now defines HAVE_DECL_TZNAME if it is declared, when
5574 HAVE_STRUCT_TM_TM_ZONE is not defined.
5575 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5576 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5577 for HAVE_TZNAME.
5579 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5581 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5582 superfluous backslashing of quotes (") in sed expressions;
5583 thanks to Paul Eggert.
5585 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5587 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5588 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5589 H. F. Beebe for the bug report.
5591 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5593 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5594 quoted -cmdline argument in Portland Group compiler (bug
5595 reported by Jeffrey J. Barteet).
5597 2004-03-25 Kevin Ryde <user42@zip.com.au>
5599 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5600 (Run Time): ... here, where it's now mentioned.
5602 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5604 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5605 inherits from language Autoconf-without-aclocal-m4.
5606 (Customizing autom4te): Adjust example; the cache must now be
5607 disabled for language Autoconf-without-aclocal-m4.
5609 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5610 Nathanael Nerode <neroden@twcny.rr.com>

5618 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5619 AC_CHECK_TARGET_TOOLS, and warn for future changes
5620 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5621 AC_CHECK_TOOLS.
5622 (Specifying Names): Document the reason for these future
5623 behavioral changes.
5624 * tests/mktests.sh: Do not generate tests for the
5625 new macros.
5626 * NEWS: Document these changes.
5628 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5629 they make TeX hang up.
5631 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5633 * NEWS: New macro AC_CHECK_ALIGNOF.
5634 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5635 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5636 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5637 vowel.
5638 (AC_CHECK_ALIGNOF): New macro.
5639 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5640 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5641 those for sizeof.
5643 2004-03-03 Paul Eggert <eggert@twinsun.com>
5645 * bin/Makefile.am (edit): Don't use $< in a context where
5646 POSIX doesn't require support for it. Use $@.in instead.
5647 Problem reported by Anthony N. Frasso in
5648 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5649 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5651 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5653 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5654 from the next generation of Libtool.
5655 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5657 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5659 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
5660 is not always thread-safe. Report from Nathanael Nerode.
5662 2004-02-18 Paul Eggert <eggert@twinsun.com>
5664 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5665 problem on QNX reported by Stephen Rasku in
5666 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5668 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5669 $(m4sh_m4f_dependencies); this removes a FIXME.
5670 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5671 (MAINTAINERCLEANFILES): Split into pieces,
5672 one per related section. Add $(srcdir)/wrapper.in.
5674 2004-02-09 Paul Eggert <eggert@twinsun.com>
5676 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5677 AC_SUBST provides no portable way to escape literal newlines.
5679 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5680 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5681 Darwin uses -lcrt2.o and there's little point to cataloging all
5682 the system variants. Partial fix reported by Andreas Waechter in:
5683 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5684 for bug reported by Nelson H. F. Beebe in:

5687 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
5689 * doc/autoconf.texi (AU_DEFUN): Fix English,
5690 suggested by Paul Eggert.
5691 * lib/autoconf/autoupdate.m4: Correct reference to
5692 acobsolete.m4, suggested by Alexandre Duret-Lutz.
5694 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
5696 * bin/autoupdate.in: Define __file__ so that warnings
5697 refer to the correct file.
5698 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5699 the behavior of the third argument.
5700 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5701 correctly the behavior of the third argument. Document
5702 what the three macros that AU_DEFUN defines do. Fix
5703 warning message when the third argument includes $0
5704 (reported by Alexandre Duret-Lutz).
5706 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5707 Eric Sunshine <sunshine@sunshineco.com>
5708 Paul Eggert <eggert@twinsun.com>
5710 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5711 (AS_INIT): Output shell initialization there. Removed optional
5712 parameter. Expand _AS_SHELL_FN_SPY.
5713 (AS_INIT_WITH_SHELL_FN): Removed.
5714 (_AS_SHELL_FN_SPY): New macro.
5715 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5716 macros.
5717 (AS_SHELL_SANITIZE): Remove loop to find better shell
5718 and documentation for the parameter.
5719 (_AS_DETECT_BETTER_SHELL): Move it here.
5720 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
5721 (_AS_RUN): Move it here, support testing with eval.
5722 (AS_REQUIRE_SHELL_FN): Require shell functions when
5723 it is used.
5724 (_AS_LINENO_WORKS): Put around braces, we do not
5725 trigger the bash bug anymore.
5726 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5727 use AS_INIT_WITH_SHELL_FN.
5728 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5730 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5732 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
5733 * doc/autoconf.texi: Don't say that the third parameter
5734 is broken.
5735 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5736 (AU_DEFUN): Honor the third parameter, create autoupdate
5737 macros with AU_DEFINE.
5738 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
5739 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

5747 * lib/autoconf/status.m4: Remove FIXME.
5748 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
5749 that the macro is not present anymore in the updated
5750 configure.ac.
5751 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
5752 of autoupdate.

5757 copyright years.
5758 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5759 2003 (except 1997) to the list of copyright years. This undoes
5760 the 2003-05-22 change, which removed the older years from the list.
5761 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5763 2004-01-27 Gary V. Vaughan <gary@gnu.org>
5764 Albert Chin-A-Young <china@thewrittenword.com>

5767 grep or ggrep program in PATH that accepts as long lines as
5768 possible.
5769 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5770 AC_PROG_GREP.
5771 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5772 egrep and fgrep respectively if $GREP -E/-F don't work.
5773 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5774 _AC_PROG_GREP, and AC_PROG_SED.
5775 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5776 longest input length accepted by a command.
5777 (AC_PROG_SED): Use it.
5778 * doc/autoconf.texi (Particular Programs): Document the changes.
5779 * NEWS: Updated.
5781 2004-01-27 Paul Eggert <eggert@twinsun.com>
5783 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

5785 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5786 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5788 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5789 bin/autoconf.in, config/Makefile.in, config/config.guess,
5790 config/config.sub, config/install-sh, config/mdate-sh,

5803 sources.
5805 2004-01-26 Paul Eggert <eggert@twinsun.com>
5807 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5808 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5809 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5810 not <inttypes.h>. Problem reported by Tim Mooney in
5811 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5812 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5813 Likewise.
5815 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5816 otherwise "make check" fails because it forbids cmp (I guess
5817 because cmp treats files as binary on DOS-like systems).
5819 * tests/mktests.sh: Update copyright date to 2004, since some tests
5820 have changed in 2004.
5822 2004-01-23 Gary V. Vaughan <gary@gnu.org>
5824 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
5825 non-truncating sed or gsed program in PATH.
5826 * tests/acprograms.at: Add it.
5827 * doc/autoconf.texi (Particular Programs): Document it.
5828 * NEWS: Updated.
5830 2004-01-15 Paul Eggert <eggert@twinsun.com>
5832 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5833 -std1 disables some useful extensions on Tru64. Problem reported
5834 by N. Lichtmaier in
5835 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5837 2004-01-14 Paul Eggert <eggert@twinsun.com>
5839 * doc/autoconf.texi (Programming in M4sh): Document that
5840 AS_MKDIR_P succeeds if the destination is a symbolic link
5841 to an existing directory.
5842 (Limitations of Usual Tools): Note that mkdir -p might not
5843 succeed on symlinks to directories.
5845 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5847 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5848 * bin/autoheader.in: Grammar fix in message.
5849 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5850 Test for dir before calling mkdir -p. (trivial changes)
5852 2004-01-13 Eric Blake <ebb9@byu.net>
5854 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5855 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5857 2004-01-10 Jim Meyering <jim@meyering.net>

5861 2004-01-09 Paul Eggert <eggert@twinsun.com>
5863 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5864 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5865 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5866 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5867 AC_COMPILE_IFELSE, since we now assume our caller invokes
5868 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5869 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5870 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5871 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5873 2004-01-07 Paul Eggert <eggert@twinsun.com>
5875 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5876 `"'...'"`, as it's confusing (and I suspect it may not work on
5877 some platforms). The code was incorrect anyway, as it assumed
5878 that \$ evaluated to itself in that context. Reported by
5879 Alexandre Duret-Lutz.
5881 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

5933 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
5934 -c -o might not work. From a suggestion by Kevin Ryde.
5935 (C Compiler, Generating Sources, Limitations
5936 of Usual Tools, Limitations of Make, Making testsuite Scripts):
5937 Don't put '-o' after non-options, as POSIX doesn't allow this.

5991 functions work.
5992 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
5993 does not work.
5994 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

6009 them on the fly.
6011 2003-11-24 Akim Demaille <akim@epita.fr>
6013 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6264 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6265 cache variable instead of $G77 to decide whether to include -O2,

6347 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6348 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6350 2003-09-26 Akim Demaille <akim@epita.fr>
6352 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6353 directory for AC_CONFIG_COMMANDS' first argument exists.
6354 This makes valid the invocation of _AC_SRCPATH that follows.
6355 Reported by Eric Sunshine.
6356 * doc/autoconf.texi (Configuration Commands): Adjust.
6358 2003-09-26 Akim Demaille <akim@epita.fr>
6360 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6361 Reported by Ralf Corsepius.
6363 2003-09-26 Akim Demaille <akim@epita.fr>
6365 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6366 arguments.
6367 Actually, use AU_ALIAS.
6368 From Bruno Haible.
6370 2003-09-26 Paul Eggert <eggert@twinsun.com>
6372 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6373 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6374 Problem reported by Eric Sunshine in:

6379 The test suite are sometimes assigning timings incorrectly.
6380 Reported by Henk Krus.
6381 Diagnosed by Nicolas Joly.
6383 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6384 AT_help_all.
6385 Instead of making AT_help a sequence of assignments to grow
6386 $at_help_all, just make AT_help_all be the growing contents of
6387 $at_help_all, and make a single assignment in...
6388 (AT_INIT): here.
6389 (at_times_skip): Flip the meaning and rename as...
6390 (at_times_p): this.
6391 (AT_INIT): When summarizing the test that ran, remove
6392 $at_times_file after use, and check it is present before trying to
6393 use it.
6395 2003-09-25 Akim Demaille <akim@epita.fr>
6397 Version 2.57d.
6399 * bin/Makefile.am (edit): Handle '@configure_input@'.
6400 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6401 (ifnames): chmod -w.
6402 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6403 executables, not bin/ executables! Otherwise all the magic needed
6404 to find non installed files is turned off. This caused a failure
6405 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6406 as found in its environment (sent by tests/autoreconf): pointing
6407 to bin/autom4te that could not find its files.
6408 * tests/mktests.sh: Force the replacement of generated files, for
6409 the sake of "mv" program that are interactive when overwriting a
6410 -w file.
6411 * config/install-sh: Upgrade from CVS Automake.
6413 2003-09-23 Paul Eggert <eggert@twinsun.com>
6415 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6416 versus test -L issues.
6418 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6419 Paul Eggert <eggert@twinsun.com>
6421 Trivial change to support GCC's configuration procedure.
6422 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6423 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6424 about inconsistency if the preprocessor is set to give errors for
6425 any warning.
6426 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6428 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6430 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6431 and XFile.pm from Automake.
6432 * lib/Autom4te/XFile.pm: Update from Automake.
6434 2003-09-12 Akim Demaille <akim@epita.fr>
6436 Version 2.57c.
6438 2003-09-12 Akim Demaille <akim@epita.fr>

6441 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
6442 from masters.
6444 2003-09-12 Akim Demaille <akim@epita.fr>
6446 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6447 not asm/types.h.
6449 2003-09-11 Akim Demaille <akim@epita.fr>
6451 * doc/autoconf.texi (Header Portability): linux/random.h.
6452 From Peter Hendrickson.
6454 2003-09-10 Akim Demaille <akim@epita.fr>
6456 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6457 willing to edit the output files.
6459 2003-09-10 Akim Demaille <akim@epita.fr>
6461 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6462 and AC_FC_FREEFORM.
6463 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6464 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6466 2003-09-09 Akim Demaille <akim@epita.fr>
6468 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
6469 Reported by Gary Vaughan.
6470 * bin/autom4te.in (handle_m4): Likewise.
6472 2003-09-09 Akim Demaille <akim@epita.fr>
6474 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
6475 trailing files.
6477 2003-09-07 Paul Eggert <eggert@twinsun.com>
6479 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6480 Improve the accuracy of the wording about obsolescence.
6481 From a suggestion by Ian Lance Taylor in
6482 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6484 2003-09-05 Paul Eggert <eggert@twinsun.com>
6486 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6487 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6489 2003-09-04 Akim Demaille <akim@epita.fr>
6491 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6492 AC_FUNC_WAIT3.
6494 2003-09-04 Akim Demaille <akim@epita.fr>
6496 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6497 (freeze): When exiting, use $exit_code.
6498 * lib/autoconf/fortran.m4: Comment changes.
6500 2003-09-04 Akim Demaille <akim@epita.fr>
6502 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6504 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6506 Add support for newer Fortran dialects. The F77 interface is
6507 unchanged, and continues to support Fortran 77. New FC macros
6508 correspond to all the old F77 macros, with output variables FC,
6509 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6510 available dialect, but older dialects can be specified. There are
6511 new macros AC_FC_SRCEXT to set the source extension, and
6512 AC_FC_FREEFORM to accept free-form source files.
6514 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6515 New macros.
6516 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6517 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

6531 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6532 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6533 Rewrite in terms of the above.
6534 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6535 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
6536 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
6537 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
6539 2003-09-02 Paul Eggert <eggert@twinsun.com>
6541 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6542 Document problems with timestamp resolution that 'make', 'cp -p', and
6543 'touch -r' have.
6545 2003-08-27 Akim Demaille <akim@epita.fr>
6547 * tests/m4sugar.at (cross_warning): Make sure to enable the
6548 output, so that we can track spurious m4sugar output.
6549 * tests/local.at: Require 2.57.
6550 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6551 are defaulted by AT_CHECK anyway.
6552 Use AT_CHECK_AUTOM4TE.
6553 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6554 missing dnl.
6556 2003-08-27 Akim Demaille <akim@epita.fr>
6558 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6559 when -Wobsolete is set.
6560 Set it on by default.
6561 Suggested by Klee Dienes.
6563 2003-08-27 Akim Demaille <akim@epita.fr>

6623 (&verbose): Remove.
6624 (&getopt): Adjust the note and verb channels, depending upon
6625 --verbose.

6627 * bin/autoupdate.in: Adjust.
6628 Use &verb, not &verbose.
6630 2003-08-21 Akim Demaille <akim@epita.fr>
6632 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6633 &parse_WARNINGS.

6635 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6636 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6638 2003-08-21 Akim Demaille <akim@epita.fr>
6640 First stab at preserving warnings between calls to autom4te,
6641 including when the cache is used.
6643 There are still several issues: (i) there are too many runs of m4
6644 (one for include, one for warnings, and some more), (ii) warnings
6645 spreading on several lines are not handled gracefully, (iii) the
6646 code meant to have the call stack display for errors does not work
6647 (its handling should move from m4 to autom4te).
6649 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6650 Use them.
6651 (@preselect): Add m4_warn.
6652 ($exit_status): Remove, use $exit_code.
6653 ($help): Use Autom4te::ChannelDefs::usage.
6654 (&handle_m4): No longer define the m4_warnings.
6655 At each run, extract and report the warnings.
6656 Always cache the result, including if the exit status is on
6657 failure, since if nothing changes, we should result in the same
6658 failure, hence we can use the cache.
6659 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6660 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6661 Remove.
6662 (m4_warn): Redefine as a do-nothing: it is its invocation that
6663 matters, as warnings are now reported via traces.
6664 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6665 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6666 the latter reveals calls to the former.
6668 Adjust the tests.
6670 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6672 2003-08-21 Akim Demaille <akim@epita.fr>
6674 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6675 Use them.
6677 2003-08-21 Akim Demaille <akim@epita.fr>
6679 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6680 forward order.
6681 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6682 (&parse_warnings): Accept a list of warning requests.
6683 (&usage): Return a string, not a side effect.
6684 (cross): New warning category.
6686 2003-08-21 Akim Demaille <akim@epita.fr>
6688 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6689 (&require_configure_ac): Accept an optional directory argument.
6690 ($configure_ac): Remove.
6691 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6692 (&catfile): Remove.
6693 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6694 * bin/autoscan.in: Adjust.
6696 2003-08-20 Akim Demaille <akim@epita.fr>
6698 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6699 Reported by Alexandre Duret-Lutz.
6701 2003-08-20 Akim Demaille <akim@epita.fr>
6703 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6704 * bin/autom4te: Adjust.
6705 In particular, be Autoconf tools are really silent when properly
6706 working, bind the verbosity of the 'note' channel to $verbose.
6707 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6708 (&xsystem, &contents): Remove, since they are exported by...
6709 * lib/Autom4te/FileUtils.pm: this.
6710 More perldoc.
6711 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6712 * lib/Autom4te/FileUtils.pm: here.
6714 2003-08-20 Akim Demaille <akim@epita.fr>
6716 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
6717 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

6767 2003-08-14 Derek Price <derek@ximbiot.com>
6769 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
6770 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6771 shorter column three. Add DESCRIPTION to log file content.
6773 2003-08-13 Derek Price <derek@ximbiot.com>
6775 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

6818 Depend on Makefile since it contains substitutions.

6820 * lib/autom4te.in (args): Add local.at? for Autotest args.
6821 This change was made on autom4te.cfg which is generated.
6822 Reported by Raja R. Harinath.
6824 2003-06-25 Akim Demaille <akim@epita.fr>
6826 * doc/autoconf.texi (Header Portability): sys/mount.h.
6827 From Gareth McCaughan.
6829 2003-06-23 Akim Demaille <akim@epita.fr>
6831 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6832 not all of them. This fixes 1. the fact that when testing
6833 Autoconf there are many many config.log, 2. the incorrect use of
6834 top_srcdir to find config.log.
6835 Don't mix the detailed output of failed test with the summary of
6836 failures. Rather, append detailed log afterwards.
6838 2003-06-23 Akim Demaille <akim@epita.fr>
6840 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6841 always run: output config.log on $at_group_log.
6843 2003-06-23 Akim Demaille <akim@epita.fr>
6845 * tests/torture.at (#define header templates): Don't use quotes in
6846 C++ comments as it puzzles Emacs' sh font-lock-mode.
6848 2003-06-23 Akim Demaille <akim@epita.fr>
6850 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6851 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
6852 * tests/atspecific.m4: Rename as...
6853 * tests/local.at: This.
6854 * tests/suite.at: Move the globals into...
6855 * tests/local.at: here.
6856 * tests/Makefile.am: Adjust.
6857 * doc/autoconf.texi (testsuite Scripts): Adjust.
6859 2003-06-21 Kevin Ryde <user42@zip.com.au>
6861 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6862 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6863 ensuring we add -std1 for full-ANSI.
6865 * doc/autoconf.texi (hdrindex): New macro.
6866 Add index entries for portability of various standard header files.
6868 2003-06-20 Akim Demaille <akim@epita.fr>
6870 * configure.ac: Bump to 2.57b.
6872 2003-06-20 Akim Demaille <akim@epita.fr>
6874 Version 2.57a.
6876 2003-06-20 Akim Demaille <akim@epita.fr>
6878 * bin/autom4te.in: Don't rely on $HOME being defined.
6879 Reported by Marc Espie as PR/233.
6881 2003-06-20 Akim Demaille <akim@epita.fr>
6883 * lib/autotest/general.m4: Use at_times_file only if used.
6884 From Nicolas Joly.
6886 2003-06-20 Akim Demaille <akim@epita.fr>
6888 * config/config.guess, config/config.sub, config/elisp-comp,
6889 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6890 Update from masters.
6892 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6894 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6895 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6896 (TEST_SCRIPT): New diversion.
6897 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6898 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6899 (AT_INIT): Support for expected failures.
6901 2003-06-02 Akim Demaille <akim@epita.fr>
6903 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6904 changes.
6905 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6906 Autoconf nor Automake.
6907 (&contents): New, from Automake.
6908 PODify.
6910 2003-05-28 Paul Eggert <eggert@twinsun.com>
6912 * NEWS, doc/autoconf.texi (Particular Functions),
6913 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
6914 is the inverse of localtime.
6916 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
6918 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
6919 (handle_exec_errors): New function. Work around $! being
6920 altered by WEXITSTATUS.
6921 (xqx, xsystem): Use handle_exec_errors.
6923 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
6925 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
6926 Do not call `_exit()', simply modify `$?'.
6927 (xsystem): Reset $! before running system, and check it afterward.
6928 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
6929 63 for version mismatches.
6931 2003-05-23 Akim Demaille <akim@epita.fr>
6933 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
6934 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
6935 the middle of a line).
6936 * lib/m4sugar/m4sugar.m4: Likewise.
6937 Remove useless spaces in comments.
6939 2003-05-23 Akim Demaille <akim@epita.fr>
6941 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
6942 exit 63, so that we (or Automake's "missing") can tell the
6943 difference with a plain failure.
6944 * doc/autoconf.texi (Notices): Adjust.
6946 2003-05-23 Akim Demaille <akim@epita.fr>
6948 * Makefile.am, bin/Makefile.am, config/Makefile.am,
6949 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
6950 White spaces cleanup.
6952 2003-05-22 Jim Meyering <jim@meyering.net>
6953 Paul Eggert <eggert@twinsun.com>
6955 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
6956 Remove `#include <stdlib.h>' from the list; we should never
6957 make confdefs.h include <stdlib.h> or <cstdlib>, because the
6958 resulting namespace pollution would cause other tests to fail.
6959 Configure scripts run with some older versions of g++ and HP's
6960 aCC would fail due to such an #include. Problems reported by
6961 Matthew Mueller in <http://bugs.debian.org/120704> and by
6962 Keith Bostic in
6963 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
6964 In the test, use the test declaration before including <stdlib.h>,
6965 as that's closer to how it'll be used.
6967 2003-05-23 Akim Demaille <akim@epita.fr>
6969 * doc/autoconf.texi (Header Portability): ucred.h.
6970 From Ian Redfern.
6972 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
6974 Overhaul Autotest's logging: generate separate log files
6975 in testsuite.dir/NNN/testsuite.log, and append them to
6976 testsuite.log instead of re-running the test verbosely.
6978 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
6979 file descriptor, write 0 to at_status_file instead of setting
6980 at_status=0, initialize some new variables (at_status_file,
6981 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
6982 to rerun the tests, instead append the at_group_log to the
6983 at_suite_log when a test fails.
6984 (AT_SETUP): pipe the test case's output into at_tee_pipe,
6985 with the AS_MESSAGE_LOG_FD redirected to stdout.
6986 (AT_CLEANUP): save the output status in $at_status_file
6987 and restore it, redirect the AS_MESSAGE_LOG_FD back to
6988 its original place.
6989 (AT_CHECK): since tests are run with a redirected stdout,
6990 and used to be re-run in verbose mode, turn some $at_verbose
6991 into echo, and don't redirect the output of testing stdout
6992 and stderr.
6994 * lib/autotest/autoconf.texi (testsuite Scripts): Update
6995 the name of the debugging directory and information about
6996 its contents.
6998 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7000 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7001 parameter.
7003 2003-05-22 Akim Demaille <akim@epita.fr>
7005 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

7032 2003-05-22 Akim Demaille <akim@epita.fr>
7034 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

7067 2003-05-17 Akim Demaille <akim@epita.fr>
7069 * lib/autoconf/functions.m4: Use the default includes so that
7070 memcmp be declared before being tested.
7071 Reported by Sander Niemeijer.
7072 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7073 * doc/autoconf.texi (Default Includes): Document
7074 AC_INCLUDES_DEFAULT.
7076 2003-05-17 Akim Demaille <akim@epita.fr>
7078 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
7079 * doc/autoconf.texi (Obsolete Macros): Adjust.
7080 Reported by Werner LEMBERG and Debian Bug 190886.

7113 and truncate.
7115 2003-05-06 Akim Demaille <akim@epita.fr>
7117 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7118 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7119 by aclocal.m4 is changed it might require the importing of another
7120 m4 extension file, i.e., aclocal must be run.
7122 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7123 (&parse_args): Use --force with aclocal if required and supported.
7124 (&autoreconf_current_directory): Use &run_aclocal.

7131 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7132 argument instead of a file name, so that the request file remains
7133 open during the whole autom4te run.
7134 ($icache_file): New.
7135 (&freeze): Lock the $icache_file.
7137 2003-04-29 Derek Price <derek@ximbiot.com>
7139 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7140 seperator with m4_append_uniq(). It doesn't work.
7141 (AT_CLEANUP): Add `;' to end of at_help_all.
7142 (AT_INIT): Allow --keywords to be specified more than once. When
7143 grepping $at_help_all for keywords, use the field and keyword
7144 seperators to ensure a complete keyword match. Alter at_prev handling
7145 to support the new --keywords behavior.
7147 2003-04-27 Karl Berry <karl@freefriends.org>
7149 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7150 align better with others. I also made some of the individual
7151 entries on one line, for brevity and to make it easier for me to
7152 sort my dir-example file in the Texinfo distribution :).
7154 2003-04-12 Jim Meyering <jim@meyering.net>
7156 * NEWS: Mention the new macro.
7157 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

7195 (TEXI2DVI): Make it --batch.
7197 2003-03-31 Derek Price <derek@ximbiot.com>
7199 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
7200 which removed the main loop.
7201 Thanks to Akim Demaille.
7203 2003-03-29 Akim Demaille <akim@epita.fr>

7206 that starts a GUI.
7207 From Ilya Zakharevich.
7209 2003-03-29 Akim Demaille <akim@epita.fr>
7211 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
7212 documentation to read is Autoconf's.
7213 Suggested by Paul Eggert.
7215 2003-03-28 Akim Demaille <akim@epita.fr>
7217 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
7218 reading the section "Present But Cannot Be Compiled" when the
7219 header causes problems.
7221 2003-03-28 Akim Demaille <akim@epita.fr>
7223 * tests/torture.at (Configuring subdirectories): Require aclocal
7224 1.4, otherwise the test fails, as it does support configure.ac.
7225 This fixes the "test 40 failed" bug reports.
7227 2003-03-28 Akim Demaille <akim@epita.fr>
7229 * doc/autoconf.texi (C Compiler): `#line' portability.
7230 From Paul Eggert and Nelson H. F. Beebe.
7232 2003-03-27 Derek Price <derek@ximbiot.com>
7234 * lib/autotest/general.m4: Eliminate main loop and reorganize test
7235 layout in order to allow scripting around test groups.
7237 2003-03-27 Derek Price <derek@ximbiot.com>
7239 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
7240 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7241 use new diversions in preparation for accepting new arguments and

7258 sense. Verbosify the diversion definitions comment.
7260 2003-03-26 Derek Price <derek@ximbiot.com>
7262 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
7263 AS_PREPARE.

7284 file name for the m4 program, when it has an "exe" file extension.

7286 remove the error code during normalization.
7288 2003-02-28 Akim Demaille <akim@epita.fr>
7290 * doc/autoconf.texi (Present But Cannot Be Compiled): New.
7292 2003-02-28 Alexandre Duret-Lutz <adl@gnu.org>
7294 * doc/autoconf.texi (Limitations of Make): Remove the section
7295 about `$<' in inference rules, it was a bogus interpretation of
7296 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
7297 Tru64 make in the "target lookup" section.
7298 (Automake): Automake 1.5+ no longer requires special tools to be
7299 present on the developer's host.
7301 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
7303 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

7319 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7320 When constructing paths with IFS=:, quote the path. If we're
7321 constructing a DOS-style absolute path, we don't want to split it
7322 on the colon.

7373 innocuous variant befor including <limits.h> or <assert.h>. This
7374 works around a bug reported by Albert Chin: HP-UX 11i

7376 gettimeofday and many other functions.
7378 2002-12-03 Paul Eggert <eggert@twinsun.com>
7380 Version 2.57.
7382 * NEWS, configure.ac: Update version.
7384 * doc/fdl.texi: Upgrade to FDL version 1.2.
7386 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7387 nontrivially in main's body, so that f's external declaration is
7388 not optimized away in AIX. This should fix the bug reported by
7389 Martin Frydl in
7390 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.

7434 * Makefile.maint: Sync with Bison, i.e.:
7435 (po-check): Scan .l and .y files instead of the
7436 .c and the .h files that they generate. This fixes the bug
7437 reported by Tim Van Holder in:
7438 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7439 Look for N_ as well as for _. Try to avoid matching #define for
7440 N_ and _.

7496 2002-11-05 Akim Demaille <akim@epita.fr>
7498 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7499 Remove.
7500 We _have_ to stop using the old compatibility scheme that tried to
7501 avoid useless backslashes because Libtool 1.4.3 contains a
7502 AC_DEFINE([error_t], [int],
7503 [Define to a type to use for \`error_t' if it is not
7504 otherwise available.])
7505 We _have_ to quote the single quote and backslashes with \. The
7506 old compatibility scheme saw that ` was backslashed, and therefore
7507 did not quote the single quote. Hence before this patch, Autoconf
7508 was not compatible with Libtool.
7510 2002-11-04 Paul Eggert <eggert@twinsun.com>
7512 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

7531 Support -m/--make.
7532 * doc/autoconf.texi (autoreconf Invocation): Adjust.

7552 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7553 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7554 Make variable, not a shell variable.
7555 Suggested by Bruno Haible.
7557 2002-10-31 Akim Demaille <akim@epita.fr>
7559 * bin/autom4te.in (load_configuration): Reject #args out of any
7560 language.

7576 Suggested by Tim van Holder.

7581 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7582 Problem reported by Bruno Haible.
7584 2002-10-29 Akim Demaille <akim@epita.fr>
7586 * doc/autoconf.texi (Header Templates): Put also in words what the
7587 pictures says to assist free style readers.
7588 (Customizing autom4te): s/--cache=/--cache /.
7590 2002-10-29 Akim Demaille <akim@epita.fr>
7592 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and

7837 * doc/autoconf.texi (Limitations of Usual Tools): Remove incorrect
7838 words about HP-UX cmp: it was actually a user-written cmp.
7840 2002-10-22 Akim Demaille <akim@epita.fr>
7842 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
7843 are a few warnings.
7844 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
7845 Quote for Perl '' strings, not "".
7846 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
7847 strings.
7849 2002-10-22 Akim Demaille <akim@epita.fr>
7851 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
7852 characters is a syntax warning now.

7854 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

7859 `@', to tickle Perl's lists.
7860 Reported by Carlos Velasco.
7862 2002-10-18 Akim Demaille <akim@epita.fr>
7864 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

7874 2002-10-17 Akim Demaille <akim@epita.fr>
7876 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.

7897 Because of caching, some files that no longer exist and are no
7898 longer required can still cause errors.
7899 Reported by Alexandre Duret-Lutz.
7901 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
7902 to frozen files in @ARGV, as @ARGV must remain being a list of
7903 files. Rather, at M4 call sites, use this...
7904 (&files_to_options): New function.
7905 (&freeze): Use &error.
7906 (&up_to_date): If a file that was included according to the cache
7907 is no longer there, then the output is out dated.
7908 (&main): Don't even check whether a file is up to date is anyway
7909 --force is given.
7910 * tests/tools.at (autom4te cache): New.
7912 2002-10-16 Akim Demaille <akim@epita.fr>
7914 * bin/autoconf.as: Kill dead options.
7915 * bin/autoupdate.in (&parse_args): Kill old options.
7916 * bin/autoreconf.in (&parse_args): Remove dead options.
7917 Factor some code.
7918 (&autoreconf): Report the directories we enter *and leave*, so
7919 that error messages can be easily located, and use GNU Make
7920 format, so that Emacs' compile mode understands us.
7921 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
7922 if some file was changed instead of `print'.
7923 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
7924 (&parse_args): Remove the dead options.
7925 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new
7926 autoheader's quiet mode.

7931 2002-10-11 Akim Demaille <akim@epita.fr>

7934 check for compilability.
7936 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
7937 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

7939 (AC_CHECK_HEADER): this.
7941 * lib/autotest/general.m4 (AT_INIT): Include the failed test
7942 numbers in the Subject suggestion.

7956 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
7957 file name to enable parallel executions.
7958 From Sam Varshavchik.
7960 2002-10-08 Akim Demaille <akim@epita.fr>
7962 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
7963 aclocal invocation, as Gettext macros might not be visible to
7964 aclocal.
7965 Instead of blindly running autopoint, scan configure.ac (not the
7966 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
7967 Reported by Paul D. Smith.
7969 2002-10-08 Paul Eggert <eggert@twinsun.com>
7971 Work around problems found when POSIXLY_CORRECT=1 is set.
7972 None of this seems to have anything to do with POSIX, really,
7973 but it's how Perl getopt works.
7974 * bin/autom4te.in (parse_args): Configure GetOpt with
7975 "permute", too.
7976 * doc/autoconf.texi (Invoking autom4te):
7977 --warning -> --warnings.
7978 * lib/autom4te.in: --warning -> --warnings.

7997 2002-09-28 Akim Demaille <akim@epita.fr>
7999 * tests/torture.at (Configuring subdirectories): Be robust to
8000 users who use config.site to require for a cache: in this case,
8001 the two last configure runs, using two different sets of
8002 arguments, trigger a legitimate error.
8004 2002-09-28 Akim Demaille <akim@epita.fr>
8006 * tests/m4sh.at (Functions Support, Functions and return Support):
8007 New.

8020 (tm_zone): Move their rules to...
8021 * lib/autoconf/types.m4: here, using AN_ macros.
8022 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8023 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8024 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8025 * lib/autoconf/programs.m4: here.

8037 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8038 (.m4.m4f): Don't pass --prepend-include, since that's done by
8039 tests/autom4te itself.
8040 * lib/autoscan/Makefile.am: Include freeze.mk.
8041 (autoscan.list): New target --this file is no longer a source.
8042 (autoscan.pre): New file.
8044 2002-09-28 Akim Demaille <akim@epita.fr>
8046 * bin/autoscan.in (@kinds): Make them singular.
8047 Adjust all uses.
8048 (&init_tables): When --debug, report the list of rules to ease
8049 tracking changes in autoscan.list.
8050 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8052 2002-09-28 Akim Demaille <akim@epita.fr>

8063 * lib/autoscan/identifiers, lib/autoscan/makevars,
8064 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8065 `functions' line is now prefixed with `function:'.
8066 * bin/autoscan.in (&init_tables): Adjust.
8068 2002-09-28 Akim Demaille <akim@epita.fr>
8070 From now on, autoscan files must always map a macro name to a
8071 word: there is no `default' macro for autoscan.
8073 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8074 all.
8075 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8076 explicit.
8078 2002-09-28 Akim Demaille <akim@epita.fr>
8080 * bin/autoscan.in (%c_keywords): Remove.
8081 (&used): Keep only track of the words we might be interested in.

8112 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8113 Reported by Ralf Corsepius.
8114 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8116 2002-09-26 Akim Demaille <akim@epita.fr>
8118 Single suffix rules and seperated dependencies are not portable.
8120 * doc/autoconf.texi (Installation Directory Variables): Update.
8121 (Limitations of Make): Some about `Single Suffix Rules and

8136 * bin/Makefile.am (SUFFIXES, .in): Remove.
8137 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

8143 Reported by Ralf Corsepius.

8164 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest

8166 Suggested by Guido Draheim.
8168 2002-09-13 Akim Demaille <akim@epita.fr>
8170 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals

8174 2002-09-12 Akim Demaille <akim@epita.fr>
8176 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8177 the lists.
8179 2002-09-12 Akim Demaille <akim@epita.fr>
8181 * doc/autoconf.texi (Defining Symbols): Present two different

8187 * doc/autoconf.texi: Review grammar and punctuation.

8192 grammatical typos.
8193 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8194 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8195 is obsolescent.
8197 2002-09-11 Akim Demaille <akim@epita.fr>
8199 * doc/autoconf.texi (Questions): Rename as...
8200 (FAQ): this.

8215 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8216 `duplicates', since the algorithm was too naive and could keep
8217 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8218 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8219 Reported by Ralf Corsepius.

8221 cases.
8223 2002-09-09 Akim Demaille <akim@epita.fr>

8229 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8230 directory definition.
8231 Reported by Andreas Schwab and Jim Meyering.
8233 2002-09-06 Akim Demaille <akim@epita.fr>

8236 precious variables are.
8237 Suggested by Pontus Skoeld.
8239 2002-09-05 Akim Demaille <akim@epita.fr>
8241 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8242 (ifnames, autoscan, autom4te): Since we don't only depend on
8243 configure.ac variables (such as VERSION etc.), but also on prefix
8244 and so forth, depend on Makefile, not configure.ac.
8245 Reported by Alexandre Duret-Lutz.
8246 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8248 2002-09-05 Kevin Ryde <user42@zip.com.au>
8250 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes

8268 * configure.ac: Bump to 2.53d.

8270 as of today, on Automake's team suggestion.
8272 2002-09-03 Akim Demaille <akim@epita.fr>
8274 Version 2.53c.
8276 2002-09-02 Akim Demaille <akim@epita.fr>

8285 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8286 Also, tweak grammar: s/make sure to/be sure to/.
8288 2002-09-02 Paul Eggert <eggert@twinsun.com>
8290 * doc/autoconf.texi (Limitations of Builtins): Explain why logical

8295 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8296 Reported by Raja R. Harinath.
8297 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8298 * bin/autoupdate.in: Use error instead of die.
8300 2002-09-01 Paul Eggert <eggert@twinsun.com>
8302 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8303 ordinary shell concatenation rather than echo+tr+sed command that
8304 runs afoul of a long-line-related sed bug in Solaris 8.
8306 * bin/autoheader.in (parse_args): --warning -> --warnings.
8308 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8309 stdout, as traditional "ls" does.
8310 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8311 _AC_COMPILER_EXEEXT_O): Likewise.
8312 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8314 * bin/autoconf.as: Add --prepend-include option. This patch was
8315 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8316 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8318 * bin/autoconf.in, configure: Regenerate.
8320 * doc/autoconf.texi (Special Shell Variables): Mention
8321 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8323 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8324 MAILPATH and set PS1, PS2, PS4 to default values, to work
8325 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8326 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8327 the Autoconf documentation specifies; fall back to "unset" only if
8328 this fails. Use a shell for-loop for this rather than an m4 loop,
8329 to shorten the output script.
8331 2002-08-30 Paul Eggert <eggert@twinsun.com>
8333 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8334 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8335 for the CDPATH problem. Document PWD.
8336 (Limitations of Builtins): Document the problem that "cd $foo" and
8337 "ls $foo" may refer to different directories in shells conforming
8338 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8339 example, since the old example is now out of date.
8341 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8342 FOO" and "ls FOO" talk about different directories; this catches
8343 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8344 spaghetti.
8346 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8347 of rolling our own unset.
8348 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8349 in practice we needn't worry about CDPATH if unset doesn't work.
8351 * Makefile.in, aclocal.m4, bin/Makefile.in,
8352 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8353 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8354 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8355 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8356 tests/Makefile.in: Regenerate with Automake 1.6.3.
8358 * config/config.guess, config/config.sub, config/mkinstalldirs:
8359 Update.
8361 * configure: Regenerate with self.
8363 2002-08-30 Kevin Ryde <user42@zip.com.au>
8365 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8366 default output.
8368 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8370 * bin/autom4te.in (Request::load): Correctly test for "do" read
8371 failure.
8373 2002-08-29 Akim Demaille <akim@epita.fr>
8375 * lib/Autom4te/General.pm (&xqx): New.
8376 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8377 hand, which is not portable.
8378 (&error): New.
8379 * bin/autom4te.in: Use them.
8380 Use &error instead of die.
8381 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8382 Adjust.
8384 2002-08-17 Paul Eggert <eggert@twinsun.com>
8386 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8387 default list of compilers to try, since it was long ago superseded
8388 by the ksh fc builtin. Suggested by Steven G. Johnson.
8390 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8392 * doc/autoconf.texi (Invoking autom4te): End the option table,
8393 fixing a bug introduced by the previous patch.
8394 (Limitations of Make): Add a 'target lookup' subentry in the
8395 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8397 2002-07-29 Mark D. Roth <roth@feep.net>
8399 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8400 options and use $AUTOM4TE_PATH.
8401 * doc/autoconf.texi: Remove documentation of autom4te
8402 --include-envvar and --site-macro-subdir options and document
8403 use of $AUTOM4TE_PATH.
8404 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8405 arguments from each language section.
8407 2002-07-29 Paul Eggert <eggert@twinsun.com>
8409 * doc/install.texi: Include copyright symbol in copyright notice.
8411 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8412 Replace with:
8413 (AM_MAKEINFOFLAGS): New macro.
8414 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8415 * Makefile.am (INSTALL): Use the new macros.
8416 Use -o rather than --output, since "missing" does not grok --output.
8418 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8420 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8421 comments do not always work. Never trust the exit status of
8422 `make -k'.
8424 2002-07-24 Kevin Ryde <user42@zip.com.au>
8426 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8427 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8429 2002-07-23 Paul Eggert <eggert@twinsun.com>
8431 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8432 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8433 apparently treats PATH="nonexistent" as if it contained ".".
8434 Bug reported by Stefan `Sec' Zehl.
8436 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8438 * doc/autoconf.texi (Limitations of Make): Mention the special
8439 handling of the obj/ directory by BSD make.
8441 2002-07-20 Kevin Ryde <user42@zip.com.au>
8443 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8444 backslashes.
8446 2002-07-19 Akim Demaille <akim@epita.fr>

8455 2002-07-18 Akim Demaille <akim@epita.fr>
8457 Version 2.53b.
8459 2002-07-18 Akim Demaille <akim@epita.fr>
8461 * config/config.guess, config/config.sub: Update.
8463 2002-07-18 Akim Demaille <akim@epita.fr>
8465 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8466 Automake's parts.
8468 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
8469 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8470 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8472 2002-07-18 Akim Demaille <akim@epita.fr>,
8473 Alexandre Duret-Lutz <duret_g@epita.fr>
8475 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8476 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

8485 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8486 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8487 latter was not run.
8489 2002-07-17 Akim Demaille <akim@epita.fr>
8491 * lib/Autom4te/General.pm (find_file): Browse the directories in
8492 the order they are given.

8512 macro directory, remove note that include path directories are
8513 used in reverse order, and document --prepend-include option.
8514 * lib/autom4te.in: Use --prepend-include instead of --include.
8515 * tests/wrapsh.in: Use --prepend-include instead of --include.

8553 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
8555 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
8556 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
8557 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
8558 so that Emacs setups GNU style for perl-mode and cperl-mode.
8560 2002-06-27 Paul Eggert <eggert@twinsun.com>
8562 * config/install-sh: Quote $src. Prefer || to test's -o option,
8563 as per "Limitations of Builtins".
8564 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
8565 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8567 * tests/mktests.sh: Use grep instead of fgrep, as per
8568 "Limitations of Builtins".
8570 2002-06-15 Paul Eggert <eggert@twinsun.com>
8572 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
8573 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
8574 so that we consistently test the just-built programs.
8575 * tests/wrappl.as: Likewise.
8577 2002-06-12 Paul Eggert <eggert@twinsun.com>
8579 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
8580 name, so that symlinks to 'autoconf' work properly. Bug reported
8581 by Bruno Haible.
8582 * bin/autoheader.in (AUTOM4TE): Likewise.
8583 * bin/autoreconf.in (autoconf, autoheader): Likewise.
8584 * bin/autoscan.in (autom4te): Likewise.
8585 * bin/autoupdate.in (autom4te): Likewise.
8587 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
8588 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
8589 on Solaris 2.5.1.
8591 2002-06-11 Andreas Schwab <schwab@suse.de>
8593 * doc/autoconf.texi: Add more dir entries.
8595 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8597 * bin/autom4te.in ($cache): Don't define using `$me', the name
8598 of the cache should not depend on the name under which autom4te
8599 was installed.
8601 2002-06-07 Akim Demaille <akim@epita.fr>
8603 * tests/tools.at (autoconf: forbidden tokens, basic)
8604 (autoconf: forbidden tokens, exceptions): Adjust to the change of
8605 words in autom4te.in.
8607 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8609 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
8610 _AC_LANG_PROGRAM_C_F77_HOOKS.
8612 2002-06-07 Akim Demaille <akim@epita.fr>
8614 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
8615 rename as...
8616 (AC_REPLACE_FNMATCH): this.
8617 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
8618 AC_FUNC_FNMATCH_GNU.
8620 2002-06-07 Akim Demaille <akim@epita.fr>
8622 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
8623 Rosetta Stone for Unix.
8625 2002-06-07 Akim Demaille <akim@epita.fr>
8627 * bin/autom4te.in (warn_forbidden): When rejecting a token,
8628 suggest m4_pattern_allow.
8629 Suggested by Adam J. Richter.
8631 2002-06-07 Akim Demaille <akim@epita.fr>
8633 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
8634 ac_config_libobj_dir.
8635 (AC_CONFIG_LIBOBJ_DIR): New.
8636 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
8637 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
8638 Use ac_config_libobj_dir to find the replacement files.
8639 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
8640 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
8641 (AC_REPLACE_FNMATCH_GNU): these.
8642 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
8643 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
8644 * tests/mktests.sh (ac_exclude_list): Don't check
8645 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
8647 2002-06-06 Paul Eggert <eggert@twinsun.com>
8649 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8650 if ln doesn't work.
8651 * NEWS: Likewise.
8652 * doc/autoconf.texi (Configuration Links): Likewise.
8653 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
8655 2002-06-05 Paul Eggert <eggert@twinsun.com>
8657 * config/config.guess, config/config.sub, config/texinfo.tex:
8658 Update from masters.
8660 2002-05-29 Paul Eggert <eggert@twinsun.com>
8662 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
8663 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
8664 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

8671 * lib/m4sugar/Makefile.am (check-local): Likewise.
8672 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
8673 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
8675 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
8676 * doc/autoconf.texi (Particular Programs): Document them.
8677 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
8678 * NEWS: Likewise.
8680 2002-05-27 Paul Eggert <eggert@twinsun.com>
8682 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
8683 * NEWS, doc/autoconf.texi (Particular Types): Document it.
8684 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
8685 instead of AC_MBSTATE_T, which never existed.
8687 2002-05-23 Akim Demaille <akim@epita.fr>
8689 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
8690 version of Autoconf that is discussed.
8692 2002-05-22 Paul Eggert <eggert@twinsun.com>
8694 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8695 from the default list of compilers to try. Suggested by
8696 Kate Hedstrom.
8697 * NEWS: Document the above.
8698 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8700 2002-05-17 Paul Eggert <eggert@twinsun.com>
8702 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8703 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8704 This improves on an earlier suggestion by H. Peter Anvin.
8706 2002-05-16 Paul Eggert <eggert@twinsun.com>
8708 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8709 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8710 Both macros now accept an optional source-dir arg.
8711 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8713 * NEWS: Document this.
8714 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8716 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8717 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8718 not for GNU extensions; this undoes part of the 2000-11-03 change,
8719 reverting to 2.13-compatible behavior.
8720 Add new optional argument DIR.
8721 (AC_FUNC_FNMATCH_GNU): New macro.
8723 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8725 2002-05-08 Paul Eggert <eggert@twinsun.com>
8727 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8728 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8729 and it causes a 'test' syntax error if it fails.
8730 Bug reported by Stephen Gildea.
8732 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8733 If prototypes are supported, use them to check this at compile-time,
8734 instead of trying to check it at run-time. If we must do a run-time
8735 check, assume that setvbuf is standard when cross-compiling, as
8736 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8737 Bug reported by Paul D. Smith.
8739 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8740 argument specifying location of getloadavg.c. This removes a
8741 FIXME. This idea was taken from Jim Meyering's implementation in
8742 textutils.
8743 * doc/autoconf.texi (Particular Functions): Document this.
8744 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8745 that's what the code does; this fixes a bug reported by
8746 Paul D. Smith.
8748 2002-05-03 Akim Demaille <akim@epita.fr>
8750 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8751 autopoint instead of gettextize.
8752 ($uses_alocal): Rename as...
8753 ($uses_aclocal): this.
8754 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8755 Suggested by Bruno Haible.
8757 2002-05-03 Akim Demaille <akim@epita.fr>
8759 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8761 2002-04-29 Paul Eggert <eggert@twinsun.com>
8763 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8764 files to be 1 second older; just set them to be the same time.
8765 Also, sleep 1 second after the first aclocal, to work around
8766 problems with sub-second time stamps on the input files.
8768 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8770 * doc/autoconf.texi: Mention "set -e -x" lossage
8771 under node "Limitations of Builtins".
8773 2002-04-29 Akim Demaille <akim@epita.fr>
8775 * doc/install.texi: Better wording for setting variables when
8776 running configure.
8777 From Christian Cornelssen.
8779 2002-04-29 Akim Demaille <akim@epita.fr>
8781 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8782 of lack of $LINENO support, then the test will compare the $LINENO
8783 in testsuite vs. the lineno in the test file. This is wrong, of
8784 course.
8785 Be sure to protect it.
8786 Reported by Patrick Welche.
8788 2002-04-25 Akim Demaille <akim@epita.fr>
8790 * doc/autoconf.texi (Obsolete Macros): Typo.
8791 Reported by Vladimir Volovich.
8793 2002-04-25 Akim Demaille <akim@epita.fr>
8795 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8796 than some of the input files, hence, on the second run of aclocal,
8797 if some of its input are younger, make them older.
8798 Suggested by Paul Eggert.
8800 2002-04-25 Akim Demaille <akim@epita.fr>
8802 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8803 Thanks to Paul Eggert.
8805 2002-04-25 Akim Demaille <akim@epita.fr>
8807 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8808 and ac_subst_vars be sh variables containing the list of
8809 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8810 DEFAULT diversion.
8811 (_AC_INIT_PREPARE): Use them to log them.
8812 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8813 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8814 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8815 _AC_SUBST_FILES and _AC_SUBST_VARS.
8816 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8818 2002-04-24 Akim Demaille <akim@epita.fr>
8820 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8821 autoheader, so that automake does not complain about a missing
8822 config.h.in that was to be created.
8824 2002-04-23 Akim Demaille <akim@epita.fr>
8826 * bin/autoheader.in (parse_args): --warning takes an argument.
8827 Fixes PR/220.
8829 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8831 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
8832 and bb.out when cleaning up.

8840 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
8842 2002-04-22 Akim Demaille <akim@epita.fr>
8844 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
8845 comma.
8846 Reported by Gregory Giannoni.
8848 2002-04-22 Akim Demaille <akim@epita.fr>
8850 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
8851 Fixes false failures on Darwin.

8857 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

8875 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
8876 Minor spelling and grammar fixes.
8878 * doc/autoconf.texi: Follow the outline suggested in the GNU
8879 Sample Texts sections of the Texinfo 4.2 manual. Most
8880 importantly, this makes sure that the copyright notices appear in
8881 all output formats. You probably need Texinfo 4.2 to generate
8882 the manual now.
8884 Fix some bugs when using "$@" when there might be zero positional
8885 arguments in cases where this matters.

8905 * tests/c.at: We can't have zero arguments, so remove workaround
8906 that is not portable to Zsh.
8908 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8910 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
8911 from aclocal.m4 too.
8913 2002-04-12 Akim Demaille <akim@epita.fr>
8915 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
8917 2002-04-10 Akim Demaille <akim@epita.fr>
8919 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
8920 workaround for ${1+"$@"}.
8921 * doc/autoconf.texi (Shell Substitutions): Explain it.
8922 From Oliver Kiddle and Peter Stephenson.
8924 Have M4sh perform minimal shell sanitizing.
8926 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
8927 part into...
8928 (_AS_PREPARE): this new macro.
8929 (AS_PREPARE): New.
8930 (AS_INIT): Invoke AS_SHELL_SANITIZE.
8931 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
8933 Adjust Autoconf and Autotest.
8935 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
8936 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
8937 * lib/autotest/general.m4 (AT_INIT): Likewise.
8938 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
8939 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
8940 AS_SHELL_SANITIZE.
8942 Use this M4sh to generate Autoconf's shell scripts.
8944 * tests/wrapsh.as: New, precursor of wrapsh.in.
8945 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
8946 on Autotest and M4sh.
8947 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
8948 (wrapsh.in): New target.
8949 * bin/autoconf.as: New, precursor of autoconf.in.
8950 (autoconf.in): New target.
8952 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

8955 with indented comments in rules.
8957 2002-04-09 Andreas Schwab <schwab@suse.de>
8959 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
8960 ac_top_builddir when setting ac_abs_top_builddir.
8962 2002-04-06 Kevin Ryde <user42@zip.com.au>
8964 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
8965 (Portable Shell): Cross reference to Systemology.
8967 2002-04-05 Akim Demaille <akim@epita.fr>
8969 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
8970 directories when descending in a SUBDIRS.
8971 Reported by Ezra Peisach.
8973 2002-04-04 Andreas Schwab <schwab@suse.de>
8975 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
8976 contains no literal separators.
8978 2002-04-03 Akim Demaille <akim@epita.fr>
8980 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
8981 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
8982 Use dnl, not the KILL diversion.
8983 Extracted from...
8984 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
8985 (AC_CONFIG_LINKS): here.
8986 Adjust.
8987 Don't use the KILL diversion, as it kills spurious output, which
8988 results in failures being hidden.
8989 Use m4_defn where appropriate.
8990 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
8991 after the second argument.
8992 Use m4_defn.
8993 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
8994 syntax, as it is provided by M4sugar.
8995 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
8997 2002-04-03 Andreas Schwab <schwab@suse.de>
8999 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9000 expanded if $# <= 2.
9002 * bin/autoreconf.in (autoreconf): Run automake after rerunning
9003 aclocal.
9005 2002-04-03 Akim Demaille <akim@epita.fr>
9007 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)

9009 Also recognize *.bb and *.bbg as compilation byproducts.
9010 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9011 (_AC_COMPILER_OBJEXT): Use them.
9012 Fixes Debian #138666.
9014 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9016 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9018 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9019 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9020 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9021 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9022 (AC_C_CONST): Same.

9027 AC_C_CROSS.

9032 _AS_MKDIR_P_PREPARE.
9034 2002-03-28 Kevin Ryde <user42@zip.com.au>
9036 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9037 to avoid versions of HP C which don't allow that.
9039 2002-03-27 Paul Eggert <eggert@twinsun.com>
9041 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9042 (AS_SHELL_SANITIZE): Invoke it.
9043 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

9047 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9049 2002-03-26 Akim Demaille <akim@epita.fr>
9051 * doc/autoconf.texi (Introduction): The GNATS base moved.
9053 2002-03-25 Paul Eggert <eggert@twinsun.com>
9055 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9056 as POSIX requires, as it doesn't work with Zsh.
9057 * doc/autoconf.texi (Assignments): Document the problem.
9059 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9061 * doc/autoconf.texi (Limitations of Make): Mention more issue
9062 about VPATH, overriding of macros in sub-makes, and handling of
9063 SHELL.
9065 2002-03-21 Paul Eggert <eggert@twinsun.com>
9067 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9068 problem with here-document buffer boundaries.
9070 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9071 when reinvoking the shell, to work around problems with installers
9072 who put strange things like "cd" commands in their environments.
9074 2002-03-19 Akim Demaille <akim@epita.fr>
9076 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9077 From Aaron Ucko.
9079 2002-03-19 Akim Demaille <akim@epita.fr>

9087 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9088 From Nishio Futoshi.
9090 2002-03-19 Akim Demaille <akim@epita.fr>
9092 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9094 2002-03-18 Paul Eggert <eggert@twinsun.com>
9096 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9097 (Limitations of Usual Tools): Add mkdir section.
9099 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9100 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9101 back on AS_DIRNAME to compute prefixes otherwise; this is
9102 roughly what mkinstalldirs does. That way, we need not have
9103 our own filename disassembler. The old disassembler did not
9104 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9106 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9107 Create at_test_all by a series of assignments,
9108 not by a single assignment of a long string. The latter causes ksh
9109 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9110 presumably because of a buffer overrun.
9112 2002-03-14 Paul Eggert <eggert@twinsun.com>
9114 * lib/autotest/general.m4 (at_times_skip):
9115 Renamed from at_times. Now a boolean.
9116 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9117 says 'times: not found'.
9119 2002-03-14 Akim Demaille <akim@epita.fr>
9121 * bin/autoreconf.in (&study_gettextize): New.
9122 (&autoreconf): Handle newest gettextize.

9126 2002-03-13 Akim Demaille <akim@epita.fr>

9130 2002-03-13 Akim Demaille <akim@epita.fr>
9132 * doc/autoconf.texi (Header Portability): New.
9133 Add information about stdint.h and inttypes.h from Paul Eggert.
9135 2002-03-13 Akim Demaille <akim@epita.fr>
9137 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9138 -p'.
9139 From Bob Proulx.
9141 2002-03-12 Akim Demaille <akim@epita.fr>
9143 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9144 m4_require.
9146 2002-03-11 Andreas Schwab <schwab@suse.de>
9148 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9149 does not do it if --with-lispdir is given.
9151 2002-03-08 Akim Demaille <akim@epita.fr>
9153 Version 2.53.
9155 2002-03-08 Akim Demaille <akim@epita.fr>
9157 * doc/autoconf.texi (Subdirectories): Clarify that the
9158 subdirectory should exist.
9160 2002-03-08 Akim Demaille <akim@epita.fr>
9162 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9164 2002-03-08 Akim Demaille <akim@epita.fr>
9166 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9167 aliases the actual variables, and modifications of the former
9168 affect the latter.
9170 2002-03-08 Akim Demaille <akim@epita.fr>
9172 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9173 because of C-c: have m4 output in tmp files, then mv them.
9175 2002-03-08 Akim Demaille <akim@epita.fr>
9177 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9178 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9179 * bin/ifnames.in: Copyright update.

9183 * doc/autoconf.texi (Invoking autom4te): New.
9185 2002-03-05 Akim Demaille <akim@epita.fr>
9187 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9188 Kevin Ryde.
9190 2002-03-05 Akim Demaille <akim@epita.fr>
9192 Version 2.52i.
9194 2002-03-04 Akim Demaille <akim@epita.fr>
9196 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9197 * lib/autoconf/general.m4 (AC_INIT): More informative error
9198 message for LIBOBJ.
9200 2002-03-04 Akim Demaille <akim@epita.fr>
9202 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9203 parallel builds.
9205 2002-03-04 Akim Demaille <akim@epita.fr>
9207 * doc/autoconf.texi (Transforming Names): Equality between target
9208 and host is irrelevant.
9209 (Specifying Names, Canonicalizing): Remove all references to the
9210 backward compatibility hooks. Rather, collect them all into...
9211 (Hosts and Cross-Compilation): this new section.
9212 * doc/install.texi (System Type): Ditto.
9213 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9214 that `--host' implies cross-compilation.
9216 2002-03-04 Akim Demaille <akim@epita.fr>
9218 * doc/autoconf.texi (Evaluation Macros): New.
9219 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9220 useless.
9221 (_m4_foreach): Define the variant with immediate evaluation so
9222 that it contains exactly the items, not an expression which
9223 evaluation is the current item.
9224 (m4_re_string, m4_re_word): Don't over quote them.
9226 2002-03-04 Akim Demaille <akim@epita.fr>
9228 Instead of having stacking `shift's evaluated at the end, let
9229 `foreach' loops immediately evaluate them.
9231 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9232 $*. This is the n-th time I change my mind, but hopefully this is
9233 the last...
9234 (m4_lquote): New.
9235 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9236 efficient.
9237 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9238 it was only a hack for m4_text_wrap.
9239 (m4_car2): Remove, replaced by...
9240 (m4_cdr): New.
9241 (_m4_foreach): Adjust.
9242 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9243 m4_bpatsubst for clarification.

9278 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9279 translate \r\n to \n.
9281 2002-02-07 Akim Demaille <akim@epita.fr>
9283 Version 2.52h.
9285 2002-02-07 Akim Demaille <akim@epita.fr>
9287 Fix Autoconf PR/209.
9288 Also reported by Frank Denis.
9290 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9292 2002-02-07 Akim Demaille <akim@epita.fr>
9294 Fix Autoconf PR/207:
9295 AC_PREFIX_PROGRAM fails with dashed program names
9297 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9298 variable when looking for the prefix program.
9299 Now it also works for shell variables.
9301 2002-02-07 Akim Demaille <akim@epita.fr>
9303 * doc/autoconf.texi (Limitations of Builtins): More about
9304 case/esac.
9306 2002-02-06 Akim Demaille <akim@epita.fr>
9308 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9309 case/esac, some shells don't support it.
9310 Reported by Zack Weinberg.
9311 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9313 2002-02-06 Akim Demaille <akim@epita.fr>
9315 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9316 sure not to introduce newlines in at_groups.
9317 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9319 2002-02-06 Akim Demaille <akim@epita.fr>
9321 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9322 is not available.
9324 2002-02-05 Paul Eggert <eggert@twinsun.com>
9326 * doc/autoconf.texi (Specific Compiler Characteristics):
9327 Describe HP-UX cc bug workaround more accurately.
9328 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9329 not unsigned long.
9330 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9331 cross-compilers, too. This undoes some of the most recent change
9332 to this file.
9334 2002-02-05 Akim Demaille <akim@epita.fr>
9336 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9337 to make sure they are up to date when `check' is run.
9339 2002-02-05 Akim Demaille <akim@epita.fr>
9341 * doc/autoconf.texi (Making testsuite Scripts): Document
9342 package.m4.
9344 2002-02-05 Akim Demaille <akim@epita.fr>
9346 * lib/freeze.mk: New.
9348 2002-02-05 Akim Demaille <akim@epita.fr>
9350 Implement `autom4te --freeze'.
9352 * bin/autom4te.in (&freeze): New.
9353 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9354 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9356 2002-02-05 Akim Demaille <akim@epita.fr>
9358 * bin/autom4te.in (&parse_args): Implement `frozen files are
9359 optional are the sum of the previous files on the command line'.
9360 Also, pass `--reload-state=' on them, so...
9361 (handle_m4): don't.
9362 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9363 (M4sh): Rely on M4sugar.
9364 (Autotest, M4sh, M4sugar): Use frozen files.
9366 2002-01-31 Akim Demaille <akim@epita.fr>
9368 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9369 * doc/autoconf.texi (Initializing configure): Adjust.
9371 2002-01-30 Akim Demaille <akim@epita.fr>
9373 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9374 alphanumeric to `-' instead of `_'.
9376 2002-01-30 Akim Demaille <akim@epita.fr>
9378 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9379 for plain code, the other for cross-compilation code. The latter
9380 is now run with GCC only.
9381 * doc/autoconf.texi (Compilers and Preprocessors): New.
9383 2002-01-30 Akim Demaille <akim@epita.fr>
9385 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9386 values.
9387 * doc/autoconf.texi (Initializing configure): Explain how to
9388 change AC_INIT default values.
9390 2002-01-29 Akim Demaille <akim@epita.fr>
9392 * tests/torture.at (Configuring subdirectories): Use configure.in,
9393 so that aclocal 1.4 works.
9394 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9396 2002-01-28 Akim Demaille <akim@epita.fr>
9398 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9399 needs an argument.
9401 2002-01-28 Akim Demaille <akim@epita.fr>
9403 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9404 AUTOTEST_PATH *after* it was set.
9405 Don't put `.' in the PATH: the user should be precise and `./' if
9406 needed. In addition, given that the test suite does some `cd', if
9407 `.' is in the path, the `tested programs' sections will report
9408 programs found in the test suite's directory, while during the
9409 tests (performed in their own directory), these programs are no
9410 longer visible. In other words, the results is confusing and
9411 useless.
9412 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9414 2002-01-24 Akim Demaille <akim@epita.fr>
9416 Version 2.52g.
9418 2002-01-24 Akim Demaille <akim@epita.fr>
9420 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
9421 * doc/autoconf.texi: Finally add Akim as an author.
9423 2002-01-24 Akim Demaille <akim@epita.fr>
9425 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9426 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9427 Bourne. Use /bin/sh.
9428 From Andreas Buening.
9430 2002-01-24 Akim Demaille <akim@epita.fr>
9432 * config/config.guess, config/config.sub, config/texinfo.tex:
9433 Update from masters.
9435 2002-01-24 Akim Demaille <akim@epita.fr>
9437 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
9438 * config/auxdir.m4, config/cond.m4, config/depend.m4,
9439 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
9440 * config/missing.m4, config/sanity.m4, config/select.m4,
9441 * config/strip.m4: Remove, to ease sync'ing with any version of
9442 Automake.
9444 2002-01-24 Akim Demaille <akim@epita.fr>
9446 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9447 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9448 Reported by Geir Ove Myhr.
9450 2002-01-21 Akim Demaille <akim@epita.fr>
9452 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9454 2002-01-21 Akim Demaille <akim@epita.fr>
9456 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9457 message on invalid options.
9458 * bin/autom4te.in (parse_args): Don't use
9459 Autoconf::General::getopt with non valid options.
9461 2002-01-17 Jim Meyering <meyering@lucent.com>
9463 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9464 $ac_cv_exeext so we don't use an old, invalid, cached value.
9466 2002-01-11 Akim Demaille <akim@epita.fr>
9468 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9469 Meyering.
9470 * doc/autoconf.texi (Function Portability): Document the strnlen
9471 limitation.

9473 * lib/autoscan/functions: Adjust.
9475 2002-01-06 Akim Demaille <akim@epita.fr>
9477 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9478 package.m4, since is really depends upon configure.ac, not
9479 configure.
9480 * doc/autoconf.texi (testsuite Scripts): Adjust.
9481 * tests/Makefile.am (package.m4): New.
9482 EXTRA_DIST it since its a source.
9484 2002-01-06 Akim Demaille <akim@epita.fr>
9486 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9487 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9488 and PACKAGE_BUGREPORT from here...
9489 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9490 arguments.
9491 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9492 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9493 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9494 * tests/tools.at (autoheader): Adjust.
9495 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9497 2002-01-06 Akim Demaille <akim@epita.fr>
9499 * bin/autoscan.in (scan_file): Use `&used'.
9501 2002-01-03 Akim Demaille <akim@epita.fr>
9503 * doc/autoconf.texi (Output): Improved wording regarding use of
9504 AC_OUTPUT.
9505 From Olly Betts.
9507 2001-12-18 Kevin Ryde <user42@zip.com.au>
9509 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9510 sometimes needing writable input.
9512 2001-12-17 Jim Meyering <meyering@lucent.com>
9514 * doc/autoconf.texi (New Macros): Tweak wording.
9516 2001-12-14 Akim Demaille <akim@epita.fr>
9518 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9519 trailing files, don't apply `-rf' to files which might not be
9520 created by configure (core, core.*, and *.core), but just `rm -f'.
9521 Suggested by Jonathan Kamens.
9523 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9525 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9527 2001-12-14 Akim Demaille <akim@epita.fr>
9529 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9531 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
9533 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
9534 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9535 abs_srcdir, top_srcpath to abs_top_srcdir.
9536 (_AC_OUTPUT_FILES): Adjust.
9537 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9538 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9539 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9541 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9543 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
9544 C/Fortran linking on HP/UX, by extracting the Fortran library
9545 search path from the LPATH line in the $F77 -v output.
9547 2001-12-12 Kevin Ryde <user42@zip.com.au>
9549 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9550 forbidden file descriptors table.
9552 2001-11-26 Akim Demaille <akim@epita.fr>
9554 * bin/autoscan.in (%c_keywords): Build it at top level.
9555 Map to 1 in order to simplify its uses.
9557 2001-11-26 Akim Demaille <akim@epita.fr>
9559 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9560 Remove $filepath, useless.
9561 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9562 variables, they are really part of the tokens.
9563 Split the input line on spaces and then look for tokens.
9564 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9565 because of `lex$U.$(OBJEXT)'.
9566 (&scan_files): Use "@list" instead of join.
9567 * doc/Makefile.am (CLEANFILES): Add *.fns.
9569 2001-11-26 Akim Demaille <akim@epita.fr>
9571 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9572 Remove, replaced by...
9573 * tests/wrappl.in: Be common for all the Perl executables.
9574 In particular autoscan and autoheader want -I.
9575 * configure.ac: Adjust.
9576 * lib/autoscan/headers: errno.h is portable.
9578 2001-11-26 Akim Demaille <akim@epita.fr>
9580 * bin/autoscan.in (used): New.
9581 Use it.
9583 2001-11-26 Akim Demaille <akim@epita.fr>
9585 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
9586 directives.
9587 (&scan_sh_file): Remove a duplicate pattern.
9588 (&check_configure_ac): Use long options.
9589 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
9591 2001-11-26 Akim Demaille <akim@epita.fr>
9593 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
9594 Before, having a line containing the opening of a multi line
9595 comment made the whole line be ignored.
9597 2001-11-26 Akim Demaille <akim@epita.fr>
9599 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9600 (testsuite Scripts): Be one of its subsection.
9601 (Autotest Logs): New.
9603 2001-11-26 Akim Demaille <akim@epita.fr>
9605 Test groups are now run two directories deeper.
9607 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9608 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9609 at_top_builddir.
9610 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9611 top_srcdir, builddir and top_builddir.
9612 Use `at_*dir' relatively to the directory containing the
9613 suite, use `*dir' when relatively to the current group dir.
9615 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9617 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9618 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9619 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9620 spelling errors.
9622 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9624 * doc/autoconf.texi (Using System Type): Add an example of `case
9625 $host' usage so people quit using `case $target' everywhere.
9627 2001-11-22 Akim Demaille <akim@epita.fr>
9629 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9630 spotted by Jim Meyering.
9632 2001-11-16 Paul Eggert <eggert@twinsun.com>
9634 This patch implements a `long double' suggestion by Oliver Kiddle.
9636 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9637 static, to catch errors if the value isn't known at compile-time
9638 and the compiler supports dynamic arrays. Change its name from
9639 `_array_' to `test_array' to avoid potential name clashes.
9640 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9641 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9642 better than double. Catch a bug in GCC 2.95.2 x86.
9643 * doc/autoconf.texi (C Compiler): Document the above.
9644 * NEWS: Likewise.
9646 2001-11-13 Akim Demaille <akim@epita.fr>
9648 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9649 hand.
9650 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9652 2001-11-13 Akim Demaille <akim@epita.fr>
9654 * lib/autotest/general.m4 (AT_INIT): After having run the test
9655 group, go back to the initial directory, not to at_suite_dir.
9657 2001-11-13 Akim Demaille <akim@epita.fr>
9659 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9660 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9661 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9662 option.
9663 (AT_CHECK_CONFIGURE): Use absolute paths.
9664 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9665 The problem is still the old one: there is no means in M4 (that I
9666 know about) to create a defining macro, because there is no means
9667 to create `$1' etc., therefore, the defining macro ``swallows''
9668 all the arguments meant to the defined macro.
9670 2001-11-13 Akim Demaille <akim@epita.fr>
9672 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9673 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9674 configure.ac.
9675 * tests/aclocal.m4: Remove, as it is no longer used.
9677 2001-11-13 Akim Demaille <akim@epita.fr>
9679 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9680 variable names when referring to a single test group, or to
9681 `suite' when referring to the whole test suite.
9682 `at_last_test' is removed: m4 compute at_format itself.
9683 (at_stdout, at_stder1, at_stderr): New variables.
9684 (AT_CHECK): Use them.
9686 2001-11-13 Akim Demaille <akim@epita.fr>
9688 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9689 in PATH.
9690 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9691 Do it as soon as a test fails, don't wait till the end of the test
9692 suite.
9693 Don't remove $as_me.[0-9]*, since these files no longer exist.
9695 2001-11-13 Akim Demaille <akim@epita.fr>
9697 * tests/tools.at: Use absolute paths, since we are no longer run
9698 in place.
9700 2001-11-13 Akim Demaille <akim@epita.fr>
9702 Now that tests are running in their own private dir, there is no
9703 need to list the files to remove at the end of tests groups.
9705 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9706 (AT_data_files, at_data_files): Remove.
9707 (AT_CLEANUP, AT_DATA): Simplify.
9708 (AT_INIT): Adjust.
9709 Remove the group dir if !debug && !failed.
9710 * tests/atspecific.m4: Adjust.
9712 2001-11-13 Akim Demaille <akim@epita.fr>
9714 Start a new layout for Autotest: `testsuite' creates
9715 `testsuite.dir' in which the at-check-line etc. files are to be
9716 found, and `testsuite.dir/003' where the test group 3 is run.
9718 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9719 at_check_line_file, at_format, at_test_normalized, at_group_dir
9720 are new variables.
9721 Create the directories.
9722 Use absolute paths for at- files.
9723 (AT_CHECK): Adjust.
9725 2001-11-11 Michael Matz <matz@kde.org>
9727 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9728 (m4_car2): New.
9729 (m4_car): Properly quote arguments.
9731 2001-11-13 Akim Demaille <akim@epita.fr>
9733 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9734 with stricter rules on LIBOBJS.
9736 2001-11-12 Paul Eggert <eggert@twinsun.com>
9738 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9739 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9740 __PROTOTYPES too.
9742 2001-11-12 Akim Demaille <akim@epita.fr>
9744 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9746 2001-11-12 Akim Demaille <akim@epita.fr>
9748 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9749 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9750 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9751 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9752 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9753 specify to what the macro should be defined (typically to 1).
9755 2001-11-12 Akim Demaille <akim@epita.fr>
9757 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9758 From Jim Meyering.
9760 2001-11-12 Akim Demaille <akim@epita.fr>
9762 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9763 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9764 definition used by Automake where LEX is +/- "${missing} lex" and
9765 `missing' itself contains variables.
9767 2001-11-12 Akim Demaille <akim@epita.fr>
9769 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9770 Now that M4sh pushes BODY, the comments were output at the end of
9771 the test suites.
9773 2001-11-08 Akim Demaille <akim@epita.fr>
9775 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9776 that we can trace macros from aclocal.m4.
9777 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9778 obsoleted, and redirect to the former anyway.
9779 Reported by Ralf Corsepius.
9781 2001-11-08 Akim Demaille <akim@epita.fr>
9783 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be

9813 From Nicolas Joly.
9815 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9817 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing

9843 2001-11-03 Akim Demaille <akim@epita.fr>
9845 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9846 (@export_forward_subs): New.
9847 Add basename, dirname, and fileparse.
9848 (@EXPORT): Adjust.
9849 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9850 Don't look for aclocal flags if we already know aclocal is not
9851 used.
9852 Move aclocal.m4t only if it exists.
9853 Reported by Ezra Peisach.
9855 2001-11-03 Akim Demaille <akim@epita.fr>
9857 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9858 passed on command line, defaulting to ./configure.ac if present.
9859 (&maybe_autoreconf, File::Find): Remove, unused.
9860 (&autoreconf): If autoconf is not used, don't try to trace.
9862 2001-11-02 Akim Demaille <akim@epita.fr>
9864 * configure.ac: Bump to 2.52g.
9866 2001-11-02 Akim Demaille <akim@epita.fr>
9868 Version 2.52f.
9870 2001-11-02 Akim Demaille <akim@epita.fr>
9872 * config/config.guess, config/config.sub, doc/standards.texi:
9873 * config/lispdir.m4: Update from masters.
9874 * configure.ac: Bump to 2.52f.
9876 2001-11-02 Akim Demaille <akim@epita.fr>
9878 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9879 Don't run aclocal when aclocal.m4 is not from aclocal.
9880 From Ezra Peisach.
9881 Don't run libtoolize and gettextize if --install is not given.
9883 2001-11-01 Paul Eggert <eggert@twinsun.com>
9885 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9886 be invoked before _AS_LINENO_PREPARE.
9887 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9888 than character ranges.
9890 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9891 invoking AS_BASENAME. Set the locale variables to 'C' if
9892 possible, as POSIX requires this to get the traditional
9893 behavior.
9894 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9896 2001-10-31 Paul Eggert <eggert@twinsun.com>
9898 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9899 with {}, as that triggers a bug in Bash 2.05.
9901 (_AS_LINENO_PREPARE): Use Sed rather than
9902 Awk. Fix the sed prepass to work even if there are multiple
9903 instances of $LINENO on the same line. Do not substitute for
9904 other variables like $LINENOT. Do not check file dates; such a
9905 check is unreliable on sufficiently fast machines, and removing
9906 the check makes the code simpler and more reliable. Check for
9907 output and chmod failures.
9909 * doc/autoconf.texi (Special Shell Variables): Document
9910 the above.
9912 2001-10-31 Akim Demaille <akim@epita.fr>
9914 * tests/Makefile.am (atconfig): Remove this target, Automake
9915 handles it now.
9917 2001-10-31 Akim Demaille <akim@epita.fr>
9919 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
9920 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
9921 provided, while it is optional.
9922 * configure.ac: Adjust.
9924 2001-10-26 Paul Eggert <eggert@twinsun.com>
9926 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
9927 lib/Autom4te/Struct.pm:
9928 Require Perl 5.005_03 instead of just 5.005, as some tests fail
9929 with 5.005_02.
9931 * doc/autoconf.texi (Special Shell Variables): Document some
9932 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
9934 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
9935 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
9936 eval $LINENO is not portable in practice.
9938 2001-10-24 Akim Demaille <akim@epita.fr>
9940 * lib/Autom4te/General.pm (backname): New.
9942 2001-10-24 Akim Demaille <akim@epita.fr>

9947 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
9949 * doc/autoconf.texi (Shellology): Mention the problems with bash
9950 2.05's use of ANSI quoting in its `set' builtin.
9952 2001-10-22 Paul Eggert <eggert@twinsun.com>
9954 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
9955 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
9956 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
9957 POSIX decided to standardize on the int flavor of strerror_r.
9958 Always do char* test, as there's no reason not to.
9959 Assign to a char* var, to catch strerror_r that returns int*.
9961 * doc/autoconf.texi (Particular Functions):
9962 Document the above changes. Also, document the fact that
9963 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
9965 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
9967 2001-10-20 Akim Demaille <akim@epita.fr>
9969 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
9970 the executable was missing from the log.

9974 * lib/Autom4te/General.pm (&update_file): If destination is
9975 unchanged, remove the source.
9976 (&up_to_date_p): Don't be verbose, be debug.

9978 (&autoreconf): Display the full path of the configure.ac we are
9979 studying.
9980 Trace it only once.
9981 Be sure to honor --force with gettextize.
9982 Always run aclocal.
9983 * doc/autoconf.texi: Adjust.
9985 2001-10-20 Akim Demaille <akim@epita.fr>
9987 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
9988 Remove, dead.
9989 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
9990 `intl' is already present, as it refuses unless --force.
9991 (&parse_args): Use -I, --include instead of the old Autoconf
9992 options.
9993 ($localdir, $autoconf_dir): Remove.
9994 (@include): New.
9995 (&maybe_autoreconf): New, to preserve $_ for File::Find.
9997 2001-10-19 Jens Petersen <petersen@redhat.com>
9999 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

10007 * tests/torture.at (#define header templates): Adjust.
10009 2001-10-19 Akim Demaille <akim@epita.fr>
10011 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10012 comment, explain how to install automatic mode selection.
10013 From Russ Allbery.
10015 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10017 * bin/autoreconf.in (autoreconf): Display the path to the
10018 configure.ac being studied.
10020 2001-10-18 Paul Eggert <eggert@twinsun.com>
10022 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10023 long, to work around a bug in the HP C compiler version HP92453-01
10024 B.11.11.23709.GP.
10026 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10027 (AS_BASENAME_EXPR): New macro.
10028 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10029 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10030 and fall back on 'sed' only if the other two fail. This makes
10031 AS_BASENAME act more like AS_DIRNAME.
10032 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10033 contains white space.
10034 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10035 Use AS_DIRNAME, since I think it's now DOS-friendly.
10036 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10037 Allow "dirname //FOO" to return either / or //, as POSIX allows
10038 either behavior.
10040 2001-10-10 Akim Demaille <akim@epita.fr>
10042 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
10043 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
10044 From Eric Sharkey.

10048 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10049 m4_define, since...

10167 * tests/tools.at (AT_DATA_FORBIDDEN): New.

10173 * doc/autoconf.texi (config.status Invocation):
10174 CONFIG_SHELL defaults to a shell that supports LINENO if available.
10176 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
10177 shell does not support LINENO, and if CONFIG_SHELL is unset or
10178 empty, and if we can find a shell that does support LINENO,

10180 ourselves with CONFIG_SHELL.
10182 2001-10-05 Paul Eggert <eggert@twinsun.com>
10184 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it

10241 * lib/autotest/general.m4 (AT_INIT) <--help>: Catch up with reality.
10242 No longer output the list of tests.
10243 <--list>: New option.
10244 <--full-help>: Remove.
10245 Complete the short/long options duality.
10246 Various small adjustments.
10248 2001-10-01 Akim Demaille <akim@epita.fr>
10250 * doc/autoconf.texi: Use @kbd for user input.

10255 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
10256 Don't use nested parenthesization. This patch was originally
10257 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
10258 but somehow it didn't get incorporated then.
10259 * doc/autoconf.texi (Limitations of Usual Tools):
10260 Clarify remark about sed and nested parenthesization.
10262 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
10263 Report an error if the size cannot be determined even though
10264 the type exists.
10265 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10266 Check for `expr' arithmetic overflow, and for compilation failure,
10267 and invoke a new argument $4 if either is discovered.
10268 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
10269 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
10271 2001-09-28 Akim Demaille <akim@epita.fr>

10282 Output `AT_tested' only when existing.
10283 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
10285 2001-09-27 Akim Demaille <akim@epita.fr>
10287 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
10288 generates too many bug reports.
10290 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
10291 status when executing the ACTION-IF-FALSE.
10292 * tests/base.at (AC_TRY_*): Rename as...

10300 (Broken/missing compilers, AC_PROG_CPP with warnings)
10301 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
10302 (AC_PROG_CPP requires AC_PROG_CC): here and...
10303 * tests/fortran.at (GNU Fortran 77): there.
10304 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10305 AC_TRY_RUN is about compilation, not shell commands.
10306 (Test Programs): AC_TRY_RUN works as used to be advertised.
10308 2001-09-27 Akim Demaille <akim@epita.fr>
10310 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10311 Raja R Harinath:
10312 Be sure to detect when $LINENO always returns the same value.
10313 Look for the original script, basename($0) is certainly not
10314 enough.
10315 Pass the CLI arguments to `$as_me.lineno'.
10317 2001-09-25 Akim Demaille <akim@epita.fr>
10319 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

10331 * doc/autoconf.texi (Top): Wrap in @ifnottex.
10333 2001-09-23 Akim Demaille <akim@epita.fr>
10335 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
10336 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
10337 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10338 builddir, buildpath, top_builddir, and top_buildpath.
10339 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10340 the current directory.
10341 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
10342 variables *before* changing the current directory.

10345 variables.
10347 * lib/autotest/general.m4: Do not reset AT_victims.
10348 Don't compute at_srcdir nor at_top_srcdir.
10350 * tests/tools.at: Hence use top_srcdir.
10352 * tests/Makefile.am, tests/autoconf, tests/autoheader,
10353 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
10354 Remove.

10357 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
10358 * configure.ac: Build the position independent wrappers.
10360 * man/Makefile.am: Now that test wrappers are position
10361 independent, use them and drop dark envvar magic.
10363 2001-09-23 Akim Demaille <akim@epita.fr>
10365 * doc/autoconf.texi (Common Shell Constructs): Rename as...
10366 (Programming in M4sh): this.

10384 over-escaping.

10396 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>

10410 * tests/Makefile.am (package.m4): Remove.
10412 2001-09-22 Akim Demaille <akim@epita.fr>
10414 Rely on `$LINENO' when possible instead of `__oline__'.
10416 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
10417 `$LINENO' support replacement when not supported.
10418 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10419 them explicitly to be sure they are not output before this section
10420 (via m4_require). Cosmetic only.
10421 * lib/autoconf/c.m4, lib/autoconf/general.m4,
10422 * lib/autoconf/programs.m4: Replace all the occurrences of
10423 `__oline__' with `$LINENO'.

10426 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
10428 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
10429 character (u: -> ue) in a code comment.
10430 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
10431 it works.
10433 2001-09-21 Akim Demaille <akim@epita.fr>
10435 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10436 Suggested by Jim Meyering.
10438 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10440 * lib/autoconf/programs.m4: Use extensions listed in
10441 $ac_executable_extensions when looking for programs.
10443 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10445 * lib/autoconf/general.m4: Fix a small Englisho.
10446 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
10447 setting up ac_dir_suffix and ac_top_builddir.
10448 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10450 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10452 * doc/autoconf.texi (File System Conventions): Clarify the use of
10453 PATH_SEPARATOR.
10454 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
10455 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
10456 be used instead of ':'.
10457 * lib/autotest/general.m4: Replace occurrences of ':' in
10458 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10460 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10462 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10463 arguments. Fixed a typo.
10465 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10467 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10468 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10470 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10472 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10473 * bin/autoupdate.in: Ditto.
10474 * bin/autoheader.in: Reworded a few comments.
10475 * bin/autoconf.in: Reworded help text for a few options.
10476 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10477 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10479 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10481 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10482 already have $file). Set output files to binary mode (helps avoid
10483 CR issues on DOSish systems).
10485 2001-09-19 Akim Demaille <akim@epita.fr>
10487 * lib/autotest/general.m4: Englishoes.
10488 From Tim Van Holder and Alexey Mahotkin.
10490 2001-09-18 Paul Eggert <eggert@twinsun.com>
10492 * doc/autoconf.texi (Common Shell Constructs): New node,
10493 documenting AS_DIRNAME.
10494 (Limitations of Usual Tools): Refer to it when discussing dirname.
10495 Also, update discussion of POSIX standard to reflect latest draft.
10497 * lib/autoconf/c.m4:
10498 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10500 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10501 Do not pass a first argument with leading '-'
10502 to expr, by parenthesizing initial integers that might be negative.
10504 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10505 now merely checks whether it is an error to pass an argument
10506 to getpgrp.
10508 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10509 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10510 whether it is a (compile-time) error to pass an argument to
10511 getpgrp. This simpler test supports the revised documentation,
10512 and is all that AC_FUNC_GETPGRP's users really need.
10514 2001-09-18 Akim Demaille <akim@epita.fr>
10516 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10518 2001-09-18 Akim Demaille <akim@epita.fr>

10524 2001-09-18 Paul Wagland <paul@wagland.net>
10526 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10527 correctly.
10528 Add test for AS_BASENAME.
10529 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10530 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10531 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10532 * tests/base.at: Fixed the expected responses. The old ones were
10533 one line out...
10534 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10535 the documentation claims it should (and how it behaved in 2.13).
10537 2001-09-18 Akim Demaille <akim@epita.fr>
10539 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10540 the AC_CONFIG_COMMANDS invocation.
10541 This also solves the name clash problems.
10542 Don't set the package's ID.
10543 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10544 No longer to be shipped.
10545 (version.in): Remove.
10546 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10547 * lib/autoconf/status.m4: Adjust.
10548 Use `m4_PACKAGE_STRING'.
10549 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10550 the only optional argument is the name of the test suite.
10551 Expect `package.m4' to define the package signature.
10552 * lib/autom4te.in (Autotest): Add `package.m4?'.
10553 * tests/Makefile.am (package.m4): New.
10554 * tests/suite.at: ifnames is a victim.
10556 2001-09-18 Akim Demaille <akim@epita.fr>
10558 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10559 AC_LIBSOURCE, AC_CONFIG_FILES.
10560 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10561 program version string doesn't match the package's.
10562 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10563 after `(cached)'.
10565 2001-09-17 Paul Eggert <eggert@twinsun.com>
10567 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10568 Allow expression to return any value that can fit into unsigned long
10569 (not int, as before). Check for output errors.
10571 2001-09-17 Bruno Haible <haible@ilog.fr>
10573 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10574 Always include <stdio.h> and <stdlib.h>. Evaluate
10575 the expression in an extra function before these includes. Call
10576 fprintf "%d" only after ensuring the argument is of type 'int'.
10577 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10579 2001-09-17 Paul Eggert <eggert@twinsun.com>
10581 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10582 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10583 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10584 when they don't exist.
10586 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10587 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10588 need it.
10590 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10591 version with the version used by fileutils 4.1, except use
10592 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10593 we don't need it.
10595 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10597 2001-09-13 Akim Demaille <akim@epita.fr>
10599 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10600 _first_.
10601 Reported by Gerrit P. Haase.
10603 2001-09-13 Akim Demaille <akim@epita.fr>
10605 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
10606 m4_defn'ing is valid.
10608 2001-09-13 Akim Demaille <akim@epita.fr>
10610 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.

10612 Use it.
10614 2001-09-13 Akim Demaille <akim@epita.fr>

10617 m4_match.
10618 (m4_re_escape): New.
10619 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
10620 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
10621 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
10622 Likewise.
10623 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
10624 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
10625 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
10626 AT_tests_all for consistency.
10627 Set at_victims.
10628 (AT_VICTIMS): Similar to AT_KEYWORDS.
10629 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
10631 2001-09-13 Akim Demaille <akim@epita.fr>
10633 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
10635 2001-09-13 Akim Demaille <akim@epita.fr>
10637 * lib/autotest/general.m4 (AT_INIT): Create and remove
10638 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
10639 test suites can cohabit.
10641 2001-09-13 Akim Demaille <akim@epita.fr>
10643 * tests/mktests.sh: Don't output banners for empty test files.
10645 2001-09-13 Akim Demaille <akim@epita.fr>
10647 Test suites can be run independently of configure.
10649 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
10650 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

10659 * bin/ifnames.in: Rewrite in Perl.
10660 * configure.ac: Don't look for AWK.
10661 * tests/tools.at (AWK portability): Remove.
10662 (Syntax of the shell scripts): Don't check ifnames.
10663 (AT_CHECK_PERL_SYNTAX): New.
10664 (Syntax of the Perl scripts): Check ifnames.
10665 * tests/ifnames: New.

10670 test group titles.
10671 * tests/atspecific.m4 (AT_CHECK_AU_MACRO): AT_KEYWORDS(autoupdate).

10684 (_AT_CLEANUP_FILE_IF): Simplify the regexp.
10685 (AT_SETUP): Reset AT_line, AT_keywords, AT_description.
10686 No longer fill the HELP diversion.

10695 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

10698 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

10707 normalize the path, and to look for victims.
10708 * tests/semantics.at (AC_PATH_PROG & AC_PATH_PROGS)
10709 (AC_CHECK_PROG & AC_CHECK_PROGS): Use PATH_SEPARATOR.
10711 2001-09-07 Akim Demaille <akim@epita.fr>
10713 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
10714 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
10715 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
10716 related variables into `at_package_*'.
10717 * lib/autotest/general.m4 (AT_VICTIMS): New.
10718 (AT_INIT): Adjust for stand-alone/embedded test suites.
10719 (AS_MESSAGE_LOG_FD): Define and use it.

10726 Move toward possibly stand-alone test suites.
10728 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
10729 in addition, it introduces useless differences in logs.
10730 (AT_INIT): Let atconfig and atlocal be both optional.
10731 Adjust PATH computation.
10732 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.
10734 2001-09-07 Akim Demaille <akim@epita.fr>
10736 * lib/autoconf/Makefile.am (autoconf.m4f): Depends upon

10739 2001-09-05 Akim Demaille <akim@epita.fr>
10741 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'

10743 From Uwe Seimet.
10745 2001-09-05 Akim Demaille <akim@epita.fr>
10747 * bin/autom4te.in: --language is -l, not -s.
10749 2001-09-05 Akim Demaille <akim@epita.fr>
10751 Be ready to handle filenames as stupid as `dnl.at', for if even
10752 the maintainer is dumb enough to do that...
10754 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10755 excellence in M4 quotation: consider `__file__' is active.
10757 And BTW, when invoking m4, pass the --include in the right order:
10758 the wrong one.
10760 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
10761 4m.
10763 2001-09-05 Akim Demaille <akim@epita.fr>
10765 * lib/Autom4te/XFile.pm: New lib file.
10766 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
10767 * bin/autoheader.in: Use it.
10769 2001-09-05 Akim Demaille <akim@epita.fr>
10771 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

10781 * doc/autoconf.texi (autoscan Invocation): Adjust.
10783 2001-09-05 Akim Demaille <akim@epita.fr>
10785 CVS GNU M4 doesn't like `undefine(undefined)'.
10787 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
10788 New, extracted from main.
10789 Use IO::File wherever possible.
10790 (input.m4): Be constant, use -I instead of hard coding $tmp.
10791 Therefore be a quoted heredoc.
10792 Don't invoke `_au_disable', since ac was not loaded, but just
10793 `unm4.m4'.
10795 2001-08-31 Akim Demaille <akim@epita.fr>
10797 Version 2.52d.
10799 2001-08-31 Akim Demaille <akim@epita.fr>
10801 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix the
10802 previous patch.
10803 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Can create `config.hin~'.
10805 2001-08-31 Akim Demaille <akim@epita.fr>
10807 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
10808 serious problems handling heredocs in heredocs.
10809 Reported by Nicolas Joly.
10811 2001-08-31 Akim Demaille <akim@epita.fr>
10813 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.

10818 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
10820 2001-08-31 Akim Demaille <akim@epita.fr>
10822 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10823 (testsuite Scripts): There is no such thing as `atconfig.in'.
10824 And actually one diagram is missing: test suite runtime.
10826 2001-08-31 Akim Demaille <akim@epita.fr>
10828 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10829 inverse order.
10831 2001-08-31 Akim Demaille <akim@epita.fr>
10833 * bin/autoupdate.in (@include): `installcheck' revealed the path
10834 to m4sugar was lacking!
10836 2001-08-31 Akim Demaille <akim@epita.fr>
10838 * man/Makefile.am (.x.1): We really have to pass
10839 autom4te_perllibdir.
10841 2001-08-31 Akim Demaille <akim@epita.fr>
10843 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10844 debug scripts, in particular passing explicitly listed tests to
10845 run is stupid.
10847 2001-08-31 Akim Demaille <akim@epita.fr>
10849 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10850 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10851 Use directly autom4te, not autoconf.
10852 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
10854 2001-08-31 Akim Demaille <akim@epita.fr>
10856 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
10857 * bin/autoheader.in (%symbol): Strip arguments of macros.

10863 2001-08-31 Akim Demaille <akim@epita.fr>
10865 * bin/autom4te.in (&parse_args): Die on unknown languages.
10866 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10867 need for autoconf.
10868 Promote --include over --macrodir and other obsolete options.
10870 2001-08-31 Akim Demaille <akim@epita.fr>
10872 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

10874 * bin/autom4te.in ($autoconf): Pass --force.
10875 `print $out' doesn't print `$_' but `$out'.
10876 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10877 (autoheader): Pass --force since the test suite goes too fast for
10878 the time stamps.
10879 Adjust to the new autoheader messages.
10881 2001-08-31 Akim Demaille <akim@epita.fr>
10883 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
10884 Check the completeness of the #template.
10885 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
10886 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
10887 invocation.

10892 * bin/autoupdate.in, bin/autoheader.in: Adjust.
10893 Drop AC_MACRODIR dead for real.
10894 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
10895 `autoheader: `config.hin' is created'.
10896 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10898 2001-08-31 Akim Demaille <akim@epita.fr>
10900 * bin/autoheader.in: Rewrite in Perl.
10901 * tests/autoheader: Adjust.
10903 2001-08-31 Akim Demaille <akim@epita.fr>
10905 * bin/autoconf.in (--include, -I): New option.
10906 Map --localdir, --autoconf-dir onto it.
10907 Forward autom4te's options instead of interpreting them.
10908 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10909 There is no such envvar since the inception of autom4te.cfg.
10910 * bin/autom4te.in (&parse_args): Uniquify `@include'.
10911 * bin/autoupdate.in: Adjust, and perform more control.
10912 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
10913 * tests/autoconf: Dittowise.
10915 2001-08-31 Akim Demaille <akim@epita.fr>
10917 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
10918 * bin/autom4te.in (&find_file): Support `FILE?' standing for
10919 optionally `FILE'.
10920 Use -e, not -f, since /dev/null for instance is OK.
10921 (&parse_args): Adjust.
10922 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
10924 2001-08-31 Akim Demaille <akim@epita.fr>
10926 * configure.ac: Also find tested executables in bin.
10927 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
10928 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
10929 installed peer executables, only PATH is allowed to resolve it.
10930 Pass `autoconf_dir' via options, not via invisible envvars.
10931 * lib/Autom4te/General.pm (&find_peer): Remove.
10932 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
10933 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
10934 * man/Makefile.am: Let help2man rely on PATH instead of trying to
10935 find the executables for it.
10936 * tests/Makefile.am: Major cleanup. Too lazy to document...
10937 * tests/atlocal.in: Remove all the obscure envvar manipulations.
10938 We only need PERL.
10939 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
10940 indeed related to running the test suite, while passing
10941 --autoconf-dir and others is related to running non installed
10942 Autoconf executables. So don't do that, leave it to...
10943 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
10944 * tests/autoscan: New.
10945 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
10946 refer to library files: rely on --language.
10948 2001-08-29 Akim Demaille <akim@epita.fr>
10950 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
10951 s/--set/--language/.
10953 2001-08-29 Akim Demaille <akim@epita.fr>
10955 * doc/autoconf.texi: Strip the @nodes.
10956 Suggested by Paul Eggert.
10957 (Initializing configure): Typo.
10959 2001-08-29 Akim Demaille <akim@epita.fr>
10961 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
10962 Suggested by Paul Eggert.
10964 2001-08-29 Akim Demaille <akim@epita.fr>
10966 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
10967 download in a tmp dir.
10969 2001-08-29 Akim Demaille <akim@epita.fr>
10971 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
10972 case insensitive OSes out there :(

10979 * bin/autom4te.in (BEGIN): Simplify.
10980 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.

10982 (&parse_args): Support --mode, --set, and --melt.
10983 * bin/autoconf.in: Simplify and adjust.
10984 * tests/Makefile.am (AUTOMAKE): Use --set.
10985 * tests/atlocal.in: Adjust.
10986 * BUGS: distcheck and check are weak.
10988 2001-08-29 Akim Demaille <akim@epita.fr>
10990 * lib/autotest/general.m4: Use
10991 foo=`(command) 2>/dev/null`
10992 not
10993 foo=`command` 2>/dev/null
10994 (at-devnull): Rename as...
10995 (AT-devnull): this.
10996 (--clean): Remove AT-* files too.
10997 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
10998 Reported by Nicolas Joly.

11002 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

11014 Support test ranges as arguments to the testsuite.
11015 Have -e imply -d as the help text suggested.
11017 2001-08-27 Akim Demaille <akim@epita.fr>
11019 * Makefile.maint: Formatting changes.
11020 (do-po-update, po-update, cvs-update, update): New targets.

11032 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11033 Support `VAR=VAL' as arguments.
11034 Compute PATH _after_ the options processing, so that AUTOTEST_PATH

11037 2001-08-27 Akim Demaille <akim@epita.fr>
11039 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

11053 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11054 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11055 readable.
11056 Adjust callers.
11057 * doc/autoconf.texi (Configuration Actions): Document the vars
11058 available in commands.
11059 Emphasize the risks of collisions in init-cmds.

11090 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
11091 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
11092 -> ac_dir).
11093 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
11094 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.
11096 2001-08-27 Akim Demaille <akim@epita.fr>

11139 * lib/m4sugar/m4sugar.m4 (m4_acversion, m4_version_prereq): New.

11141 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
11142 the name of the directory they're in, instead of the filename,
11143 since version.m4 is now in m4sugar, but m4_acversion must not be
11144 classified as an Autoconf macro.
11145 ($input_m4): Don't qualify the path to m4sugar.
11146 Rather, pass autoconf_dir to m4.
11147 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

11165 for config.status'.

11231 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
11232 * NEWS, README, README-alpha, TODO, tests/README: This package is
11233 `Autoconf', not `autoconf' (the executable).
11235 2001-08-20 Akim Demaille <akim@epita.fr>
11237 Info readers seem to need `Index' in the index node title :(
11239 * doc/autoconf.texi: Reverse the 2001-08-15 change which
11240 simplified index node names.
11242 2001-08-20 Akim Demaille <akim@epita.fr>

11284 2001-08-20 Akim Demaille <akim@epita.fr>
11286 Huh!?!?! There are still some user EOF tags used, which prevents
11287 their use in AC_CONFIG_COMMANDS for instance...
11289 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11290 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

11353 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
11354 `$0.log' as for projects where testsuite is in src, we'd have

11369 2001-08-17 Akim Demaille <akim@epita.fr>
11371 * doc/autoconf.texi: Work around Texinfo buglets.
11372 (Transformation Rules): One example is enough, users are expected
11373 to have their brains on. And BTW, use DESTDIR.
11374 (dvar): New macro. Use it.
11376 2001-08-17 Akim Demaille <akim@epita.fr>
11378 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

11426 (cvs-dist): depends upon it.
11428 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11430 * tests/Makefile.am: Use a clean-local rule to remove
11431 autom4te.cache (it's a directory, not a file.
11432 * Makefile.am: Ditto (but maintainer-clean-local).
11434 2001-08-15 Akim Demaille <akim@epita.fr>
11436 * bin/autom4te.in (@m4_warning): New.
11437 (&handle_m4): Use it.
11438 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
11439 warnings are issued at each run.
11440 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
11441 is in the src tree.
11443 2001-08-15 Akim Demaille <akim@epita.fr>

11446 don't waste time running `autoupdate --version' works.
11447 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11449 2001-08-13 Akim Demaille <akim@epita.fr>
11451 * doc/autoconf.texi (ma): Rename this index as...

11474 * doc/autoconf.texi, doc/install.texi: Add a copyright notice

11502 * tests/mktests.sh: Update year in copyright notice.
11504 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11506 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11508 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11510 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11511 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11512 * doc/autoconf.texi (C Compiler Characteristics): Update
11513 documentation for AC_C_BIGENDIAN.
11515 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11517 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11518 magic values from an object file when cross-compiling.
11519 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11521 2001-08-10 Akim Demaille <akim@epita.fr>
11523 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11524 effects.
11525 Suggested by Russ Allbery.
11527 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11529 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11530 current $prefix to the sub-configures.
11532 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11534 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11535 extension (needed on BeOS). Reported by Guido van Rossum.
11537 2001-08-09 Akim Demaille <akim@epita.fr>
11539 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11541 2001-08-07 Akim Demaille <akim@epita.fr>
11543 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11544 removed.
11545 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11546 No need to remove the files before and after the each test, before
11547 each test and at the end of the suite is enough.
11548 Display only the children `times', not the shell's.
11549 If the test failed or was skipped, at-times is not available.
11551 2001-08-07 Akim Demaille <akim@epita.fr>
11553 Always produce testsuite.log, including when there are no
11554 failures. This helps getting information on skipped tests, and
11555 duration of the tests. Err, implement the latter btw.
11557 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11558 Dump information on the first run of each test.
11559 (AT_CLEANUP): Create `at-times' containing the duration of the
11560 test group.
11562 2001-08-07 Akim Demaille <akim@epita.fr>
11564 The use of `dumpstat' revealed that `len' was used although it
11565 should not. m4_text_wrap was using it, but in the Autoconf world
11566 where it is legal. Hence (i) test M4sh in its own world, not
11567 Autoconf's, and (ii), ahem, fix the bug :)
11569 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11570 does not like `' instead of [].
11571 (AT_INIT): Forbid `^_?AT_'.
11572 And don't output such tokens.
11573 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11574 `script.as', and `autom4te.cache'.
11575 Remove `empty' and `macro' which are no longer used.
11576 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11577 * tests/m4sugar.at: Use it.
11578 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11580 2001-08-07 Akim Demaille <akim@epita.fr>
11582 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.

11599 Don't rely on M4sugar outputting the patterns in files, since we
11600 might process the output _without_ running m4, hence without these
11601 files.

11604 * bin/autom4te.in (@Request::includes): Remove, unused.

12168 cross-language link tests can be performed successfully.
12169 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12170 after $LIBS, for consistency; this should be the general rule since
