1 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
3 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
4 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
6 2006-12-01 Eric Blake <ebb9@byu.net>
8 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
9 cross-compiling from cygwin to mingw.
10 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
11 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
12 to lib/autoconf/c.m4.
14 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
16 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
17 string for more reliable failure. Wrap the entire test that
18 causes the broken Solaris printf to dump core, in a subshell,
19 so the segmentation fault message is reliably suppressed.
20 Fix shell expansion errors by using /usr/ucb/echo always;
21 avoid an error on systems without it by another subshell.
22 Avoid m4 expansion of `$1'. Set the zeroth argument of the
23 subshell-$as_echo to `as_echo', for better error message.
25 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
27 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
28 `BASH_SOURCE' contain a newline, set them to empty, as they may
29 not be unset.
31 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
33 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
34 years and is too hard to maintain now. The last straw was
35 reported by Jerker Baeck in
36 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
37 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
38 * doc/autoconf.texi (Particular Functions): Move
39 AC_FUNC_SETVBUF_REVERSED from here...
40 (Obsolete Macros): ... to here. Say that it does nothing now.
41 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
42 Turn into (almost) a no-op.
44 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
45 (AC_C_VOLATILE):
46 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
47 These macros are obsolescent and new applications shouldn't need them.
48 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
49 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
50 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
51 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
52 (AC_FUNC_VPRINTF): Likewise.
53 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
54 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
55 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
57 * doc/autoconf.texi (Setting Output Variables): Mention that
58 @VAR1@VAR2 has unspecified behavior. Problem reported by
59 Ralf Wildenhues.
60 * NEWS: Mention this.
62 * Makefile.am: Put only a single '#' into the copyright notice,
63 so that it's also present in the output file. Standardize wording
64 in makefile copyright notices to match GNU coding standards.
65 * bin/Makefile.am: Likewise.
66 * doc/Makefile.am: Likewise.
67 * lib/Makefile.am: Likewise.
68 * lib/freeze.mk: Likewise.
69 * lib/autoconf/Makefile.am: Likewise.
70 * lib/autoscan/Makefile.am: Likewise.
71 * lib/autotest/Makefile.am: Likewise.
72 * lib/m4sugar/Makefile.am: Likewise.
73 * man/Makefile.am: Likewise.
74 * tests/Makefile.am: Likewise.
75 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
76 one-line file.
78 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
80 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
81 in the sed script that mangles the awk script: delete up to the
82 first exclamation mark only.
83 * tests/torture.at (Substitute and define special characters):
84 Test '!' too.
86 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
88 Rewrite config files generation: avoid quadratic growth in
89 the number of substituted variables by using awk instead of sed
90 for the bulk of the substitutions.
91 * NEWS: Mention this.
92 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
93 forbidden in the output (and thus input) file.
94 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
95 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
96 generate just one large awk script for substitutions,
97 eliminating much of the earlier complexity, while adding some
98 new complexity. Only expand the substitution templates at
99 configure time, for smaller configure script size. If
100 _AC_SUBST_FILES are used, test 'awk' for working getline support
101 at config.status time. If absent, interpolate through the
102 shell. The awk script was written with much help
103 from Paolo Bonzini and Paul Eggert.
104 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
105 (_AC_SED_FRAG_NUM): Likewise.
106 (_AC_SUBST_CMDS): Renamed from...
107 (_AC_SED_CMDS): ...this.
108 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
109 * tests/torture.at (Substitute a 2000-byte string): Also
110 substitute a line with 1000 words, and a variable with several
111 long lines.
112 (Substitute and define special characters): Test awk special
113 characters, and put substitution input strings `@foo@' in the
114 output, to test that no recursion happens; test several other
115 combinations from Paolo Bonzini.
117 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
119 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
120 that replaced echo with AS_ECHO where this wasn't necessary.
121 Problem reportd by Ralf Wildenhues.
122 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
123 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
124 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
126 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
128 * lib/freeze.mk (GREP): Removed, no need to initialize this.
130 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
132 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
133 that traditional Awk lacks 3-arg "split". It has it.
134 Mention that FS must be a single character, and a few other
135 99-byte limits of traditional Awk.
136 Mention that if (i in a) doesn't work with traditional Awk.
138 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
140 * tests/autotest.at (BSx641-newline in command):
141 (BS-BS-newline in command, BSx640-newline in command):
142 (Newline-CODE-BS-newline in command):
143 (Single-quote-BS-newline in command):
144 (Single-quote-newline-BS-newline in command):
145 Use printf '%s\n' instead of echo, for portability to hosts
146 where echo interprets backslashes. This will break on hosts
147 that lack printf, but for now let's assume all such hosts
148 are dead (if not, we should get reports of test failures).
150 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
152 'echo' has some portability problems, when given a first argument
153 with a leading '-', or when given any argument containing '\'.
154 Avoid using 'echo' in these cases.
155 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
156 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
157 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
158 * lib/autotest/general.m4 (AT_INIT): Likewise.
159 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
160 argument might be unportable.
161 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
162 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
163 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
164 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
165 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
166 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
167 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
168 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
169 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
170 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
171 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
172 (AC_PROG_MAKE_SET): Likewise.
173 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
174 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
175 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
176 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
177 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
178 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
179 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
180 * bin/autoconf.as: Redo verbose flag implementation, as the old
181 scheme wouldn't work with AS_ECHO.
182 * lib/autotest/general.m4 (AT_INIT): Likewise.
183 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
184 Don't use ECHO_T, since ECHO_N is now reliable.
185 * lib/autotest/general.m4 (AT_INIT): Likewise.
186 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
187 rather than using a here-document to put the script into a file.
188 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
189 use AS_ECHO.
190 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
191 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
192 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
193 bug, but we might as well stop using ECHO_N and ECHO_C internally.
194 * lib/autotest/general.m4 (AT_SETUP): Likewise.
195 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
196 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
197 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
198 operand, as AS_ECHO requires. Avoid double file name expansion.
199 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
200 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
201 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
202 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
203 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
204 Double-quote strings that would otherwise contain M4 comments.
205 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
207 * configure.ac (AC_INIT): Bump to 2.61a.
208 * NEWS: Likewise.
210 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
212 Version 2.61.
214 * configure.ac (AC_INIT): Bump to 2.61.
215 * NEWS: Likewise.
217 * tests/autotest.at (Macro with backslash in a test title):
218 Comment out for now, as this tests neither fails nor passes
219 reliably. Problem reported by Ralf Wildenhues.
221 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
223 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
224 in previous change, which caused test failures.
226 2006-11-16 Stepan Kasal <kasal@ucw.cz>
228 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
229 code for --enable, --disable, --with, and --without to...
230 (_AC_INIT_PARSE_ENABLE): ... a new macro.
231 * doc/autoconf.texi (Package Options):
232 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
234 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

277 no further ado.
279 2006-11-05 Karl Berry <karl@gnu.org>
281 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

293 first argument may also contain dots.
295 2006-11-09 Paul Eggert <eggert@cs.ucla.edu>

298 benefit of platforms like Solaris+GCC where it is common to have a
299 non-working g++ installation.
301 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

313 Imported from a similar patch to gnulib by Bruno Haible.
315 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
317 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

333 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
334 and Stepan Kasal <kasal@ucw.cz>
336 Handle special characters in test case titles correctly.
337 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
338 properly.
339 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
340 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
341 argument. Extend to check titles printed by ./micro-suite and
342 ./micro-suite -l and the title in micro-suite.log.
343 (Backquote in a test title,
344 Single-quote in a test title,
345 Double-quote in a test title): Don't expect failure anymore.
346 (Backslash in a test title): Put a non-whitespace character after the
347 backslash so that Bourne shells might actually see it as an escape
348 sequence.
349 (Brackets in a test title,
350 Pound in a test title,
351 Comma in a test title,
352 Quoted Macro in a test title,
353 Macro in a test title,
354 Macro with single-quote in a test title): New tests.
355 (Macro with backquote in a test title,

357 Macro with backslash in a test title): New tests expected to fail.
358 * tests/torture.at (#define header templates): M4-quote this title in
359 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
360 The visible effect was a stray [] in the testsuite output.
362 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
364 * doc/autoconf.texi (Limitations of Builtins): Do not invoke

367 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
369 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
370 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
371 5363) simply issues a warning when dividing by zero at compile
372 time. Problem reported by Elias Pipping.
374 2006-10-26 Eric Blake <ebb9@byu.net>
376 * THANKS: Update.
377 * doc/autoconf.texi (Evaluation Macros): Improve the example to
378 show effect on macros that expand with commas.
379 Reported by Joel E. Denny.

384 2006-10-25 Paul Eggert <eggert@cs.ucla.edu>
386 * doc/autoconf.texi (Slashes): Document Tru64 4.0 bug reported by
387 Jim Meyering.
389 2006-10-25 Stepan Kasal <kasal@ucw.cz>

392 `--force' always rewrites the output file.
394 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
396 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
397 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
399 2006-10-24 Stepan Kasal <kasal@ucw.cz>
401 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
403 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
405 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
406 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
407 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
408 reported by Nelson H. F. Beebe for Coreutils 6.4.
410 * tests/tools.at (autoconf --trace: user macros): Remove test
411 for tracing multiline macros, since m4 1.4.7a uses a different
412 way to number lines. Problem reported by Ralf Wildenhues.
414 2006-10-24 Stepan Kasal <kasal@ucw.cz>
416 * bin/autom4te.in (handle_m4): Do not redirect stdin to
417 /dev/null since the heuristics for interactive behaviour was
418 fixed in CVS m4.
420 * bin/autom4te.in: With --force, always refresh the output
421 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.

473 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
474 looking for special shell characters.
475 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
476 macro defined by AS_VAR_PUSHDEF before passing it as a
477 parameter.
478 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
479 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):
480 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW, AC_CHECK_MEMBER):
481 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL):

488 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
490 (Imported from Automake.)
491 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
492 which incorrectly sets the mode of an existing destination
493 directory. In some cases the unpatched install-sh could do the
494 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
495 system. We hope this is rare in practice, but it's clearly worth
496 fixing. Problem reported by Alex Unleashed in
497 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
498 Also, don't bother to check for -m bugs unless we're using -m;
499 suggested by Stepan Kasal.
501 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
503 Import this change from Automake:
505 2006-08-23 Alexandre Duret-Lutz <adl@gnu.org>

507 is enabled by default with gnu and gnits strictness.
508 Report from Bruno Haible.
510 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
511 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in
512 gnu and gnits modes.
514 Import this change from Config:
516 2006-09-20 Ben Elliston <bje@gnu.org>
517 * build-aux/config.sub (score, score-*): New.
519 Import this change from Gnulib:
521 2006-09-16 Karl Berry <karl@gnu.org>
522 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
523 to avoid sectioning errors.
525 Import these changes from Texinfo:
527 2006-10-04 Karl Berry <karl@gnu.org>
528 * build-aux/texinfo.tex (\singlequotechar): rename to \codequoteright.

531 (\lquoteexpand, \quoteexpand): new defs.
532 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
533 (\code): must use new \...Char values, since now ` is active.
535 2006-08-26 Karl Berry <karl@gnu.org>
536 * build-aux/texinfo.tex (\textdegree): New command.
538 2006-08-12 Karl Berry <karl@gnu.org>
539 * build-aux/texinfo.tex (error \box0): smaller font.
541 2006-10-14 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
543 * doc/autoconf.texi (Autoheader Macros): Fix syntax error.
545 2006-10-13 Stepan Kasal <kasal@ucw.cz>
547 * doc/autoconf.texi (Autoheader Macros): Warn that the text
548 added to the template can get mangled.
550 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
552 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
553 include the default headers, and redefine obstack_chunk_alloc
554 and obstack_chunk_free. Fixes false failure with glibc.
556 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
558 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,
559 for backward compatibility with Libtool 1.5.22. Problem reported
560 by Ralf Wildenhues.
562 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

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

593 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
595 2006-10-11 Stepan Kasal <kasal@ucw.cz>
597 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
598 initialization which is not inherited through the environment
599 (_AS_BOURNE_COMPATIBLE): ... to this new macro.
600 (_AS_RUN): Call _AS_BOURNE_COMPATIBLE, not AS_BOURNE_COMPATIBLE.
602 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
604 * doc/autoconf.texi (Limitations of Usual Tools): Describe
605 problems with mkdir -p -m.
607 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
609 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
610 comment about ac_cpp_err; it was incorrect, and anyway
611 ac_cpp_err is being removed below.
612 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
613 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
614 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
615 nobody uses it.
616 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
617 with werror_flag and conftest.err and so forth. This is more
618 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
619 and anyway the user shouldn't normally want to see this gorp logged.
620 Problem reported by Ralf Wildenhues.
621 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
622 empty, not 'no', since the rest of the code uses 'test -z'.
624 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
626 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
627 Use a single call to AC_DO_TOKENS rather than multiple, for
628 efficiency.
629 (_AC_LINK_IFELSE): Test that resulting file is executable.
630 Problem reported by mwoehlke in
631 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
633 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
634 than creating a file to use with test -x; this is much faster.
636 2006-10-02 Bruno Haible <bruno@clisp.org>
638 * lib/autom4te.in (Automake-preselections): Add
639 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
641 2006-09-27 Stepan Kasal <kasal@ucw.cz>
643 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
644 standard error, `experr' should be used, not `expout'.
646 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
648 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
649 fseeko testing program twice; just use the earlier result.
650 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
651 Set cache var to 'unknown' (not 'no') if leaving the macro unset
652 still doesn't let the program compile.
653 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
654 failed.
656 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
657 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
658 include it, without including anything else.
659 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
660 expressions.
661 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
663 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
665 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
666 `error.h', and include it, for a `error_at_line' prototype.
667 Use a nonempty format string in the link test.
668 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
669 for a declaration of wait3.
671 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
673 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
674 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
675 can apply to constants too, and that it checks for macro defns.
676 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
677 and simply cast the identifier to void. This handles structure
678 values. Problem reported by Ralf Wildenhues.
679 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
681 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

735 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
736 --error-output, to avoid warnings with M4 2.0.
738 2006-09-19 Stepan Kasal <kasal@ucw.cz>
740 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be

753 the path at runtime.
755 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
757 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

767 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
768 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
769 for the existence of the directory at configure-time. That's
770 too late, anyway. Problem reported by Stefan Seefeld.
772 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
773 7.1.4 /usr/bin/posix/sh described by Tim Rice in
774 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
776 2006-09-11 Stepan Kasal <kasal@ucw.cz>
778 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
779 works with GNU M4 1.4.3 again; make the normalized form
780 match the current m4 message; fix the description.
781 * test/tools.at (autom4te cache): Adapt to the change.

786 to catch glibc bug 2821
787 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
789 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
790 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
791 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
792 assume C89.
794 2006-09-08 Stepan Kasal <kasal@ucw.cz>
796 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the
797 preselections ...

814 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
815 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
816 accept files with extension `.f'. For consistency, also prefer
817 xlf over f77.
818 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
819 from last patch.

840 except the first two arguments are reversed.
841 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
842 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer

844 * lib/autoconf/general.m4 (AC_CACHE_CHECK_INT): New macro,
845 equivalent to the old AC_COMPUTE_INT.
846 (AC_COMPUTE_INT): No longer caches or reports. New signature.

853 * NEWS: AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_FUNC_GETLOADVG,
854 and AC_REPLACE_FNMATCH are now obsolescent in Autoconf. New
855 programs should use their Gnulib counterparts.
856 * doc/autoconf.texi (Particular Functions): Likewise.
857 (Macro Names, testsuite Invocation): Replace uses of these
858 obsolete macros with uses of non-obsolete macros.

882 simplify the code.
884 2006-08-25 Paul Eggert <eggert@cs.ucla.edu>
886 Fix Lex library problem reported to us by Julio Garvia.
887 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
888 for the default, which the user can override.
889 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
890 deal with LEXLIB.
891 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
892 didn't work if some values were cached but not others. Test for
893 broken lex libraries like native ia64-hp-hpux11.22; see
894 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
895 work around the problem by preferring an empty LEXLIB to -lfl or
896 -ll. Let the user set LEXLIB='' to indicate no library needed.
898 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
899 * README: Likewise.
900 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

995 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
996 64-bit preprocessor ints. Check for static initialization of
997 long long. Remove unnecessary casts.
999 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1001 * doc/autoconf.texi (Particular Programs): Mention that
1002 @INSTALL@ and @MKDIR_P@ may vary for different output files.
1003 Reported by Alexandre Duret-Lutz.
1005 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
1007 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
1008 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
1009 Bill Northcott in
1010 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
1012 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
1014 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
1015 pacify insanely picky compilers. Problem reported by Eric Blake.
1017 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
1018 longer supported by Sun.
1020 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
1022 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
1023 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
1024 -Wundef -Werror". Problem reported by David Fang in
1025 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
1026 * doc/autoconf.texi (Header Templates, Default Includes):

1028 (Particular Headers, Generic Headers, Generic Declarations, Guidelines):
1029 (Obsolete Macros, AC_FOO_IFELSE vs AC_TRY_FOO):

1041 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1042 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1043 this.
1045 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1047 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1048 problems with arg script text that doesn't end in newline, and
1049 with '-e a...'. Problems reported by Ralf Wildenhues.
1051 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1053 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1054 check for libXt by a check for libX11.
1056 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1058 * doc/autoconf.texi (config.status Invocation): Adjust according
1059 to last change.
1061 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1063 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1064 --help' should mention that `--version' outputs configuration
1065 settings. Report by Bruno Haible.
1067 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1069 Fix test suite failures reported by Pierre in
1070 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1071 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1072 the compiler created a file "b.out" when it didn't create anything
1073 at all.

1075 Discard stderr too, when invoking the test script.
1077 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
1079 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
1080 in the restoring of the werror flag.
1082 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>

1085 less skeptical about "volatile", after discussion with
1086 Bruno Haible on bug-gnulib.
1087 (Limitations of Usual Tools): Warn about sed stripping
1088 leading white space from text. From Bruno Haible.
1090 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1092 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1093 compiler complains about it, even if things works after the
1094 complaint. Problem reported by Peter O'Gorman.
1096 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1097 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1098 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1100 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1102 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1103 after -R regardless of host. Patrick Welche reports that this
1104 fixes things on NetBSD 3.99.

1110 to match M4 1.4.5.
1112 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1114 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1115 under AC_C_VOLATILE.
1116 (Volatile Objects): Be a little less skeptical about what
1117 "volatile" means. Derived from thoughts by Ben Pfaff in
1118 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1120 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1122 * doc/autoconf.texi: Fix some typos.
1124 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1126 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1127 more globally, since the 2006-06-30 patch didn't suffice. Problem
1128 reported by Keith Marshall. Also, don't bother with builddir2,
1129 since it shouldn't be needed any more.
1131 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1133 * doc/autoconf.texi (Generic compiler characteristics):
1134 Document AC_COMPUTE_INT. Fix wrong statements on Default
1135 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.

1140 AC_COMPUTE_INT.
1142 * NEWS: Document change.
1144 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1146 * doc/autoconf.texi (Volatile Objects): New section.
1148 * NEWS: Document previous change.
1150 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1152 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1153 Require that long long int be at least 64 bits wide. C99 requires
1154 this and enough programs depend on it so we should check for it.
1155 Bruno Haible reports in
1156 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1157 that long long int is 32 bits wide with some nonstandard compilers.
1158 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1160 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1162 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1163 to a nonexistent file, so that we don't have to worry about
1164 a local site configuration that doesn't use /usr/local.
1165 Problem reported by Keith Marshall in
1166 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1168 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1170 * doc/autoconf.texi: Be more consistent about using @acronym with
1171 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1172 quite right (it talked about "OSF/Tru64", even though the
1173 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1174 and it even mentioned "OSF 4"!) and at this point there's little
1175 reason to talk about OSF any more, since it died in 1994.
1176 (Specific Compiler Characteristics): Simplify example of
1177 negative-size array.
1178 (File Descriptors): Reorder to make the text flow better.
1179 Remove joke about "appreciate the various levels"; I didn't get it.
1180 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1181 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1182 (File Descriptors, Limitations of Usual Tools):
1183 Tone down the advice against renaming or removing open files.
1184 (Limitations of Usual Tools): Add a new section, on 'rm'.
1186 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1188 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1189 -lXt in LIBS, idea from Karsten Hopp; this was due since
1190 this change:
1192 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1193 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1194 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1195 (which belong to Xt, not X itself). See Debian bug 327655.
1197 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1199 * configure.ac (AC_INIT): Bump to 2.60a.
1200 * NEWS: Update.
1202 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1204 Version 2.60.
1206 * configure.ac, NEWS: Update.
1208 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1210 * config/texinfo.tex: Sync from upstream.
1212 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1213 quadrigraph correctly in traces.
1215 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1216 Fix typos.
1218 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1219 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1220 not defined.
1221 * doc/autoconf.texi (Changed Directory Variables): New node,
1222 to document the whole `datarootdir' business a bit better.
1223 * NEWS: Update.
1224 * tests/torture.at (datarootdir workaround): Extend test.
1225 Prompted by report by Alexandre Julliard.
1227 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1229 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1230 when using default mode of IBM C 6 for AIX. Problem and two-line
1231 fix reported by Larry Jones.
1233 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1235 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1236 about literal '${datarootdir}' if a definition is found in the
1237 output file.
1239 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1241 * NEWS: Use "M4" rather than "m4" when appropriate.
1242 Problem reported by Eric Blake.
1243 * doc/autoconf.texi: Likewise.
1244 Use @acronym around BSD, GCC, and GNU when appropriate.
1245 (Why GNU M4): Renamed from "Why GNU m4".
1246 (Redefined M4 Macros): Mention that Posix
1247 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1248 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1249 to int.
1251 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1253 * bin/autom4te.in (handle_output): Do not forbid the empty
1254 pattern.
1255 * tests/tools.at (autoconf: the empty token): New test.
1257 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1259 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1260 calls, so that we do not care whether they are LIFO or FIFO;
1261 in the m4_wrap, do not check which diversion is the topmost
1262 one, just check that the stack is balanced at the end.
1263 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1264 base diversion forever--pop the previous diversion before
1265 opening the new one; consequently, remove the m4_wrap call.
1266 * lib/autotest/general.m4 (AT_INIT): Likewise.
1267 * tests/m4sugar.at: Do not use
1268 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1270 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1271 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1273 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1274 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1275 Rework example of m4wrap token-pasting trouble so that it doesn't
1276 care whether it's LIFO or FIFO.
1277 Fix some "contrary to"s that are awkward in English.
1279 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1281 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1282 to `yes' instead of `int$1_t' if the type is found, for more
1283 consistent configure output (where $1 is the number of bits).
1284 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1285 Suggested by Bruno Haible.
1287 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1288 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1289 with system headers. Report by Bruno Haible.
1291 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1293 * config/config.guess, config/config.sub: Sync from upstream.
1295 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1296 in order to avoid picking up an older installed frozen m4sh.m4f.
1297 Besides an outdated shell startup, this could have been created
1298 by an earlier M4 version with incompatible frozen file format.
1300 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1302 * README: Recommend m4 1.4.4 instead of 1.4.3..
1303 * doc/autoconf.texi: Likewise.
1304 (Special Chars in Names): Say that $(.FOO) is portable, as
1305 suggested by Stepan Kasal.
1306 (Installation Directory Variables, Build Directories):
1307 (Automatic Remaking, Subdirectories, Fortran Compiler):
1308 (Making testsuite Scripts, Defining Directories):
1309 Quote variable usages better.
1310 (Making testsuite Scripts): Add clean-local rule to makefile
1311 snippet, by Eric Blake.
1312 (Installation Directory Variables): Fix table item font.
1313 Reword slightly to clarify. Generalize advice about
1314 not using special characters to include all file-related
1315 vars, not just VPATH.
1316 (Special Chars in Variables): Warn about special characters in
1317 $(srcdir) too.
1318 (Assignments): Clarify default-value example as suggested by
1319 Ralf Wildenhues in
1320 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1321 (Special Shell Variables): Note leading ./ or ../, as suggested
1322 by Eric Blake.
1323 (Limitations of Builtins): Under cd, warn about CDPATH.
1324 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1325 Ralf Wildenhues.
1327 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1329 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1330 `@var', for texi2html.
1331 (Systemology): Some more word wrapping, for DVI output.
1332 (autom4te Invocation): The short option for `--melt' is `-M',
1333 not `-m'.
1335 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1337 * doc/autoconf.texi: More formatting and English tweaks,
1338 many suggested by Ralf Wildenhues.
1339 Reword to avoid "@code{...}'s" and the like, since it's ugly
1340 with Emacs info mode. discontents -> woes.
1341 Put a few "will"s back. time stamp -> timestamp.
1342 side-effect -> side effect.
1344 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1346 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1347 Warn about $@ not persisting. Problem reported by Julien Danjou in
1348 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1349 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1350 Mention other special chars, too.
1352 2006-06-14 Eric Blake <ebb9@byu.net>
1354 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1356 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1358 * doc/autoconf.texi: Some systematic minor improvements, as
1359 follows. Use "makefile" when talking about makefiles
1360 generally (which might be named "makefile" or "Makefile" or even
1361 "foo.mk"), "Makefile" when talking about a specific makefile
1362 called "Makefile". This unclutters the text from weird quotes
1363 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1364 values" rather than "@var{foo}s" and similar constructs containing
1365 "}s". Use "Make rules" rather than "Makefile rules". Minor
1366 English-language improvements. Change the prefix "sub-" to "sub"
1367 and "re-" to "re".
1368 Put blank lines around examples more consistently.
1369 Avoid "rather" and "very" as intensifiers.
1370 Avoid "will" as an auxiliary.
1371 (Limitations of Make): Split this node into....
1372 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1373 (Leading _ in Macro Names, Backslash-Newline-Newline):
1374 (Backslash-Newline Comments, Long Lines in Makefiles):
1375 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1376 (obj/ and Make, make -k Status, VPATH and Make):
1377 (VPATH and Double-colon, $< in Explicit Rules):
1378 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1379 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1380 New nodes, resulting from splitup of Limitations of Make.
1381 All cross-references changed. Raise the top node from
1382 a section to a chapter, and all subnodes accordingly.
1383 Redo the introductory wording to match the new organization.
1384 (Installation Directory Variables): Use an example that is
1385 closer to what Autoconf actually does. Mention that VPATH's
1386 value should not contain metacharacters or white space.
1387 (Fortran Compiler): Fix a VPATH bug in an example.
1388 (Leading _ in Macro Names): Mention that this problem is no longer
1389 of practical concern.
1390 (VPATH and Make): Reword the advice to make it clearer
1391 that Autoconf and Automake support VPATH in non-GNU make, but
1392 many packages have bugs in this area.
1393 ($< in Explicit Rules): Refer to Build Directories rather
1394 than using a (non-VPATH-safe) example.
1395 (Automatic Rule Rewriting): Mention the sort of disaster that
1396 can ensue with Solaris-style rule rewriting with VPATH.
1398 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1400 * doc/install.texi (Compilers and Options): Weaken the
1401 suggestion to use GNU make for VPATH builds.
1403 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1404 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1406 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1407 in regular expression.
1409 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1411 * doc/autoconf.texi (Installation Directory Variables):
1412 Drop extra @samp from `@table @samp' item.
1413 (Limitations of Usual Tools): Comment fix.
1414 Do not nest @samp just to point to other table items.
1415 (Writing testsuite.at) <AT_CHECK>: The second argument to
1416 `@dvar' is already @samp'ed.
1417 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1418 do not use @var in the second argument.
1420 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1422 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1423 $as_shell.exe too. Problem reported by Andreas Buening in
1424 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1426 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1428 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1429 `unused variable' compiler warning, for `-Wall -Werror'.
1430 Reported by Jaap Haitsma in
1431 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1433 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1435 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1436 case the compiler dumps core. Problem reported for
1437 OpenServer 5.0.7 by Tim Rice in
1438 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1439 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1440 Likewise.
1442 2006-06-06 Tim Rice <tim@multitalents.net>.
1444 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1445 "ERROR" only shows up in "make check" output if there is an
1446 error.
1448 2006-06-06 Eric Blake <ebb9@byu.net>
1450 * tests/tools.at (automatically allowed tokens): Fix typo.
1452 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1454 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1456 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1457 typically overflows on x86 CPUs, even though the C standard
1458 requires otherwise.
1460 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1462 * configure.ac (AC_INIT): Bump to 2.59e.
1463 * NEWS: Update.
1465 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1467 Version 2.59d.
1469 * config/texinfo.tex: Sync from upstream.
1471 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1472 seen, invoke libtoolize with `--ltdl' argument.
1473 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1474 * NEWS: Update.
1475 Suggested by Eric Blake.
1477 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1479 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1480 reported by Ralf Wildenhues.
1481 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1483 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1485 * THANKS: Update.
1487 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1489 * doc/autoconf.texi: Modernize some of the references to Solaris.
1491 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1493 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1494 message issued by AC_REQUIRE.
1495 * tests/m4sugar.at: Check m4_require's error message.
1496 * tests/base.at: Check AC_REQUIRE's error message.
1497 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1498 to...
1499 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1500 AT_CHECK_M4.
1501 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1502 `expout' as the last parameter.
1503 * tests/tools.at: Adapt to the above change.
1505 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1507 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1508 information about race-free implementations of mkdir.

1513 * bin/autoconf.as (Usage): Likewise.
1514 * bin/autom4te.in (help): Likewise.
1515 * doc/autoconf.texi (autom4te Invocation): Likewise.
1517 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1519 * NEWS: GNU make now recommended for VPATH builds.
1520 Mention that some macros are now documented to be obsolescent.
1521 * doc/autoconf.texi:
1522 Prefer "current" to "modern" to describe
1523 currently-used (albeit perhaps old-fashioned) hosts.
1524 Mention which ancient features no longer need to be worried about.
1525 setgid -> set-group-ID
1526 setuid -> set-user-ID (these are the Posix terms)
1527 Fix some misuses of "only".
1528 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1529 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1530 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1531 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1532 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1533 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1534 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1535 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1536 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1537 Mention that these macros are obsolescent.
1538 (Installation Directory Variables): shall -> should
1539 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1540 Mention that it's now safe to use 3 and 4.
1541 (Limitations of Usual Tools): cp -r is now specified by Posix.
1542 Omit longwinded and obsolescent discussion of cp -f.
1543 Modernize discussion of expr, ls.
1544 (Limitations of Make): Modernize discussion of VPATH builds.
1545 Mention $? as a workaround in some cases.
1546 * doc/install.texi (Basic Installation):
1547 Mention "./configure; make; make install" first. Be more
1548 specific about why this file is generic. Remove unnecessary
1549 parens. Remove misleading "only". Remove obsolete advice
1550 about csh. Don't say "configure" takes awhile; say it
1551 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1552 and CC=c99 rather than CC=c89, as these are blessed by current
1553 Posix. Recommend GNU make if doing a VPATH build.
1555 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1557 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1558 examples involving shell prompts.
1560 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1561 and Paul Eggert <eggert@cs.ucla.edu>
1563 * doc/autoconf.texi (Here-Documents): Add details about the
1564 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1565 use "here-documents" instead of "here documents".
1567 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1569 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1571 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1573 * doc/autoconf.texi (File System Conventions): Warn about ":"
1574 anywhere in directory names.
1576 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1578 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1579 about quoting the case statement, just in case.
1580 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1581 was fixed in ksh93g; reported by Ralf Wildenhues.
1583 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1585 * doc/autoconf.texi (System Services): Do not document
1586 overriding EXEEXT via ac_cv_exeext=ext.
1587 (Particular Programs) <AC_PROG_MKDIR_P>:
1588 Document that ${MKDIR_P} understands --.
1589 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1590 comment.
1592 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1594 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1595 argument with leading hyphen. Problem reported by Paul Eggert.
1597 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1599 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1600 about quoting ac_try: quote all of it, if any of it seems suspicious.
1601 This means we don't have to worry about ${ or sed any more.
1602 Also, double-quote the case statement, to work around misuses via
1603 underquoting as reported by Ralf Wildenhues in
1604 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1605 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1606 undocumented and dangerous macro.
1607 Problem reported by Ralf Wildenhues in
1608 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1610 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1612 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1613 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1614 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1616 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1618 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1619 since evidently some packages rely on the old, broken behavior.
1620 Problem reported by Ralf Wildenhues in
1621 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1622 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1623 pre-2006-05-26 definitions, but leave in the comments that
1624 these macros are dangerous and should not be used.
1625 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1626 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1627 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1628 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1629 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1631 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1633 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1634 the use of 'tr', since this is our only use of 'tr'.
1636 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1637 and Paul Eggert <eggert@cs.ucla.edu>
1639 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1640 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1642 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1644 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1645 the output file in the `${datarootdir}' test.
1647 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1648 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1650 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1651 mention of `datarootdir' in the input file(s), but literal
1652 `${datarootdir}' in the output file, and we haven't warned yet,
1653 then warn as well: the user may have (erroneously) used
1654 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1655 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1656 * tests/torture.at (datarootdir workaround): Extend this test.
1657 * NEWS: Update.
1659 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1660 and Paul Eggert <eggert@cs.ucla.edu>
1662 * doc/autoconf.texi (autoheader Invocation): The first argument to
1663 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1664 alternatives and clear up the language a bit.
1666 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1668 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1669 ac_config_guess, ac_config_sub, ac_configure.
1670 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1671 Fix typo that prevented an unnecessary space from being removed.
1672 Problems reported by Ralf Wildenhues in:
1673 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1675 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1677 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1678 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1679 Don't use the term "thread-safe" to talk about mkdir race
1680 conditions, since the problem is more a process than a thread
1681 issue. Problem reported by Stepan Kasal in:
1682 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1683 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1684 the test for 'install' more closely. Look at MKDIR_P first.
1685 Look in the PATH, and at /opt/sfw/bin.
1686 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1687 Don't bother to try mkdir -p, since we already check mkdir --version;
1688 just look at the version number. (There's no easy way to check
1689 for race-free implementations.)
1690 * tests/tools.at (autoconf: subdirectories): Adjust to above
1691 changes, since MKDIR_P now might end in "/mkdir -p".
1693 * doc/autoconf.texi (autoheader Invocation): Mention that the
1694 first arg of AC_DEFINE_UNQUOTED must be a literal.
1695 Problem reported by Ben Pfaff in
1696 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1698 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1699 * doc/autoconf.texi (Special Chars in Variables): New section.
1700 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1701 (Installation Directory Variables): Quote $(datadir) better.
1702 (Limitations of Builtins): Describe some of eval's trickiness.
1704 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1705 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1706 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1707 in front of every arg, not just trailing args. Quote apostrophes.
1708 (_AC_EVAL_ECHO): New macro.
1709 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1710 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1711 removed.
1712 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1713 exposed by quoting of eval argument. Put the command on line line
1714 so it logs better.
1715 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1716 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1717 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1718 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1719 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1720 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1721 Use eval more safely.
1722 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1723 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1724 to be replaced.
1725 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1726 lines, exposed by quoting of eval argument.
1728 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1729 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1731 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1732 initialization of `ac_cv_exeext', do not override it if it was
1733 already set, unless it was set to `no', for compatibility with
1734 Autoconf-2.13, and comment this.
1735 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1736 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1737 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1738 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1739 Document that this test may be overridden by setting
1740 `ac_cv_exeext'.
1742 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1744 Revert these two patches:
1746 2006-04-06 Eric Blake <ebb9@byu.net>
1747 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1748 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1749 2006-04-01.
1751 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1752 Clean up _AC_COMPILER_EXEEXT* macros.
1753 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1754 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1755 ac_file to the name of the default output file and call
1756 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1757 initial `rm' of the candidate files...
1758 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1759 the same list in subsequent `rm' calls, and for the temporary
1760 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1761 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1762 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1763 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1764 no longer needed) by libtool. Make it a cache check.
1765 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1766 copied here by mistake.
1767 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1768 _AC_COMPILER_EXEEXT.
1769 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1770 _AC_COMPILER_OBJEXT directly.
1771 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1773 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1775 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1776 Fix description of how the buggy `sed' works.
1778 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1780 Sync from Automake:
1782 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1783 ENOLCK. Only mention `make -j' when applicable. Only raise
1784 fatal errors when `make -j' is involved. Improve error message.
1786 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1788 * doc/autoconf.texi (Here-Documents): We now know more about
1789 the variable expansion in here documents bug.
1790 Thanks to Tim Rice and Stepan Kasal.
1792 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1793 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1795 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1797 * tests/autotest.at (Multiline command from M4 expansion):
1798 No failure to be expected if the shell quotes newlines in
1799 commands in the `set -x' output. Report by Tim Rice.
1800 * THANKS: Update.
1802 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1804 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1805 expansion in the here-documents used by config.status, as that
1806 runs afoul of the Korn shell version M-12/28/93d bug described in
1807 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1808 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1809 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1811 2006-05-23 Jim Meyering <jim@meyering.net>
1813 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1814 Fix typo introduced with 2006-04-02 change. It reversed the sense
1815 of the test.
1817 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1819 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1820 ac_dB slightly, to save bytes in the script.
1821 Max out at 50 lines, rather than 96; this is more likely
1822 (though not guaranteed) to avoid obscure 'sed' failures.
1824 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1826 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1827 `tr -d -' as bad option argument. Work around this by deleting
1828 an unrelated character.
1829 Report by Tim Rice <tim@multitalents.net>.
1831 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1832 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1833 Stepan Kasal <kasal@ucw.cz>
1835 * doc/autoconf.texi (Particular Programs): Do not promise that
1836 we always prefer the GNU version of the program, and that we
1837 search according to PATH; both rules can have exceptions.
1838 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1839 AC_PROG_SED. Move descriptions of limitations
1840 to the Limitations of Usual Tools section.
1841 (Limitations of Usual Tools) <sed>: Mention script length
1842 limitations with Solaris /usr/ucb/sed.
1843 <grep>: Fix wording for empty alternative. Mention that -c and
1844 -l should not be combined, and that -E and -F should not be
1845 combined.
1847 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1848 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1850 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1851 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1853 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1855 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1856 AC_DEFINE is now passed to m4_pattern_allow.
1857 * NEWS: Mention that; likewise for AC_SUBST.
1858 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1859 the parameter to m4_pattern_allow.
1860 * tests/tools.at: Add a check for that.
1862 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1864 * lib/autoconf/status.m4: Fix typos.
1866 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1868 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1869 only the files that this macro generates.
1871 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1873 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1874 the HP-UX sed limitation of 99 commands, labels do not count.
1875 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1876 in the comment.
1877 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1879 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1881 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1882 Import the following fix from coreutils:
1884 2006-01-13 Jim Meyering <jim@meyering.net>
1886 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1887 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1888 not double-quote uses of that variable, to accommodate the rare
1889 case in which getmntent is available in none of the libraries
1890 checked. This happens at least on FreeBSD 5.0.
1892 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1894 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1895 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1896 some other programs unwisely rely on these undocumented vars.
1897 But put in warning comments about them.
1898 Problem reported by Ralf Wildenhues in
1899 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1900 * NEWS: Document that these variables are intended to go away.
1902 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1904 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1905 and set the language to C++ (analogous to the equivalent Fortran
1906 tests).
1908 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1909 * doc/autoconf.texi (C++ Compiler): Document it.
1910 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1911 * NEWS: Update.
1913 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1915 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1916 that caused config.status to generate 100-command sed scripts; the
1917 portable limit is 99.
1919 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1921 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1922 variable `ac_d' instead of `d' to avoid infringing namespace.
1923 Report by Ralf Menzel.
1925 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1927 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1928 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1929 * tests/tools.at (autoconf: subdirectories): New test, taken from
1930 the corresponding problem report by Ralf Wildenhues in:
1931 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1933 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1934 Quote some uses of shell variables if they might suffer unexpected
1935 globbing. This doesn't fix all instances of quoting problems that
1936 I found, just the easy ones that look safe.
1937 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1938 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1939 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1940 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1941 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1942 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
1943 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
1944 Likewise.
1945 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
1946 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1948 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1950 * bin/autoreconf.in ($help): Reword according to the manual.
1951 Suggested by Olly Betts.
1953 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1954 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1956 * bin/autoreconf.in: Pass the directory argument to
1957 `require_configure_ac'. Fix comment.
1958 * tests/torture.at (Configuring subdirectories): Expose this.
1959 Reported by Olly Betts.
1961 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1963 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1964 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1965 Automake as follows:
1967 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1968 `$configure_in' instead of `configure.in', to preserve
1969 directory component.
1971 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1973 * config/config.guess, config/config.sub, config/texinfo.tex,
1974 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1976 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1978 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1979 test for C99 conformance; (bool) 0.5 is an integer constant
1980 expression, but (bool) -0.5 is not. Problem reported by Fedor
1981 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1983 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1985 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1986 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1987 Warn about obsolete install-sh files. Remove stray sentence
1988 fragment and fix cross reference.
1989 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1990 install -d; this undoes the 2006-05-10 change.
1991 (MKDIR_P): Mark with AN_MAKEVAR.
1992 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1993 that we don't require $INSTALL to be thread-safe. Move comments
1994 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1995 of AC_PROG_INSTALL. Output a message saying that we're checking
1996 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1997 MKDIR_P instead of AC_SUBST.
1998 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1999 Special magic for MKDIR_P, too.
2000 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2001 a dnl.
2002 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2004 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2006 Sync from Automake, as follows:
2008 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2009 * config/install-sh: Initialize IFS, so field splitting isn't
2010 turned off later.
2011 * config/mkinstalldirs: Likewise.
2012 * config/missing: Remove superfluous quotes. Replace all uses of
2013 `[' by `test', for consistency, and for..
2014 * config/missing (sed_minuso, sed_output): New variables.
2015 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2016 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2017 Fixes `missing' to detect `--output' for help2man. Fixes
2018 PR automake/483. Report by Dennis J. Linse.
2019 (autom4te): Document in `missing --help'.
2021 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2023 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2024 * config/install-sh: Don't use 'path' to talk about file names,
2025 as per GNU coding standards. Close a race condition reported by Ralf
2026 Wildenhues and Stepan Kasal. There is still a race condition
2027 on hosts that predate Posix 1003.1-1992, but we can't help this.
2028 Don't mishandle weird characters like space on pre-Posix hosts.
2029 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2030 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2031 AC_PROG_MKDIR_P from AS_MKDIR_P.
2032 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2033 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2034 earlier editions are not (including Automake 1.8.3).
2035 Do not suggest mkinstalldirs for thread-safety.
2036 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2037 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2038 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2039 presence of special characters and race conditions.
2040 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2041 in Autoconf's name space.
2043 2006-05-10 Bruno Haible <bruno@clisp.org>
2044 and Paul Eggert <eggert@cs.ucla.edu>
2046 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2047 from Automake with minor changes.
2048 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2050 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2052 * config/install-sh: Update to Automake CVS version, as follows:
2053 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2054 * lib/install-sh: Simplify the expr implementation of dirname.
2055 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2056 * lib/install-sh: Handle --, and diagnose unknown options.
2058 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2060 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2061 `./autom4te' to create `./testsuite', since the `all' target
2062 will ensure its presence, but `installcheck' should not create
2063 the uninstalled wrappers.
2065 * tests/torture.at (Unusual Automake input files): Skip if we
2066 detect automake < 1.8.
2068 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2070 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2071 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2072 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2073 * NEWS: Update.
2075 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2077 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2078 munge (multiple) white space and other oddities.
2079 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2080 single quotes in variable assignment.
2081 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2082 and similar failures by adding multiple spaces, tabs, and other
2083 special characters.
2084 Report and different test suggested by Francesco Romani
2085 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2087 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2088 single quotes, we only need to search for single quotes; this
2089 both simplifies the search pattern, and makes us less
2090 susceptible to `echo' variations for arguments not containing
2091 single quotes.
2092 (_AC_ARG_VAR_VALIDATE): Likewise.
2094 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2096 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2097 `$*' and IFS concatenation issue with traditional shells and
2098 bash-2.04. Report by Seanster@Seanster.com.
2100 2006-05-03 Bruno Haible <bruno@clisp.org>
2102 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2103 precisely which Mac OS X versions have the od problem.
2105 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2107 * doc/autoconf.texi: Use @option systematically.
2109 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2110 and Bruno Haible <bruno@clisp.org>
2112 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2113 about 'od'.
2114 (Integer Overflow): Mention the special case of integer division
2115 overflow.
2117 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2119 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2120 traditional shells like the Solaris one that do not use the
2121 first IFS character for assembling `$*'.
2122 Prompted by a related report from autoconf_bug@nro.ca.
2124 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2125 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2127 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2128 Mention more problems with the -e option.
2130 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2132 * NEWS: Typo.
2133 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2135 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2136 in URLs to improve DVI formatted output (requires texinfo 4.6).
2137 (System Services, Systemology, Shellology): Likewise.
2138 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2139 output.
2141 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2142 continuous text.
2143 (Runtime): Fix macro argument names to match description:
2144 `action-if-found' -> `action-if-true' and similarly.
2145 (Obsolete Macros): Likewise.
2146 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2147 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2148 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2150 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2152 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2154 * ChangeLog: Typo.
2155 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2156 DVI output.

2167 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2168 (Integer Overflow, Null Pointers, Buffer Overruns):
2169 (Floating Point Portability, Exiting Portably): New sections.
2170 (Writing Test Programs): Fix some langauge. Recommend exiting
2171 with status 1, not merely nonzero. Clarify exit declaration.
2172 (Run Time): Move C exit status stuff to new Exiting Portably section.
2173 (Systemology): Mention Posix and levenez. Update v7 reference.
2174 (Portable Shell): Mention the Posix shell.
2176 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2178 * bin/autoconf.as (me): Replace by as_me.
2180 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2182 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2183 since as_me isn't set yet.
2185 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2187 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2188 a few minor bugs in this area.
2190 * doc/autoconf.texi (Programming in M4sh): Comment out the
2191 documentation of AS_BASENAME, for now.
2192 (Shell Substitutions): Do not use AS_DIRNAME in an example.

2194 AS_BASENAME.
2195 * bin/autoconf.as (me): Don't use AS_BASENAME.
2196 (dir): Remove the unused variable.
2197 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2198 AS_DETECT_REQUIRED. All uses changed.

2200 All uses changed.
2201 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

2203 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2204 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2205 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2206 (_AS_DIRNAME_PREPARE): Likewise.
2207 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2208 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2209 (AS_DIRNAME): Use "dirname --".
2211 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2213 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2214 of "run time" and "run-time" changed to "runtime", for consistency.

2221 with more accuracy and detail.
2223 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2225 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2226 Archive is not officially `GNU' any more. Update URL.
2227 (Defining Directories): Likewise
2228 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2230 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2232 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2233 newline from the `trap' code to finish `config.log'; the NetBSD
2234 /bin/sh resets the exit status after an empty command, as
2235 documented in doc/autoconf.texi.
2236 Reported by Dalibor Topic <robilad@kaffe.org>.
2238 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2240 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2241 Suggested by Bruno Haible.
2243 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2245 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2246 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2247 Instead, just list the shells that we know work.
2248 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2249 changed. Be more cautious about the _cv_ variable.
2250 * tests/tools.at (Syntax of the shell scripts): Check the
2251 _cv_ variable once, at first, to avoid an internal autoconf error
2252 when sh -n does not work.
2254 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2256 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2258 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2260 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2261 use ">&-" since we're only 99.999% sure that this is portable,
2262 and since the MinGW bug is fixed in a different way.
2263 * lib/autotest/general.m4 (AT_INIT): Likewise.
2265 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2267 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2268 before opening config.log, to avoid hitting a bug on MinGW.
2270 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2272 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2273 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2274 This works around a MinGW bug reported by Eric Paire.
2275 Make sure that all writes to the log file append to it,
2276 rather than possibly losing data.
2277 * lib/autotest/general.m4 (AT_INIT): Likewise.
2279 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2281 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2282 description.
2284 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2286 * NEWS: Update.
2288 * configure.ac (AC_INIT): Bump to 2.59d.
2290 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2292 Version 2.59c.
2294 * Makefile.maint (news-date-check): Do not require a leading `*'
2295 before the release date in NEWS.
2297 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2298 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2300 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2301 the instantiated file do not contain the string 'datarootdir'
2302 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2303 @mandir@, replace the reference '${datarootdir}' by the value.
2304 * tests/torture.at (datarootdir workaround): New test.
2305 * NEWS: Advertise this temporary fixup.
2306 Based on a patch by Bruno Haible, reported and analyzed by
2307 Paul Eggert and Noah Misch.
2309 2006-04-12 Eric Blake <ebb9@byu.net>
2311 * tests/autotest.at (Debugging a failed test): Fix comment.
2313 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2315 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2316 all the changes since 2006-04-07.
2318 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2320 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2321 succeeded, but `ln -s file dir' failed, take care to remove the
2322 leftover target before the next test, to prevent its spurious
2323 failure; also make sure `ln file dir' works before selecting it.
2324 Thanks to Keith Marshall for pointing this out.
2325 * THANKS: Update.
2327 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2328 assignments in `at_debug_args', so that we put them correctly
2329 in the `run' script.
2330 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2331 Reported by Eric Blake.
2333 2006-04-11 Eric Blake <ebb9@byu.net>
2335 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2336 top-level tests after micro-suite has been run. Used in...
2337 (Debugging a successful test, Debugging script and environment),
2338 (Debugging a failed test): ...these new tests. The first of these
2339 is fixed by...
2340 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2341 macro, split out from...
2342 (AT_INIT): ...here, so that using -d also generates a run script.
2343 Document that -d inhibits top-level logging.
2344 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2345 inhibits top-level logging; debug scripts are created.
2347 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2348 check.
2349 * tests/autotest.at (Empty test, Empty check): New test to check it.
2351 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2352 from gcc.
2354 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2356 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2357 the files if a problem appears. Make the empty *.at files
2358 read-only, too. Proposed by Ralf Wildenhues.
2360 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2362 * config/Makefile.am: Add comment to force updated Makefile.in.
2364 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2365 space only patch to this file, this patch causes the Makefile.in
2366 files that include freeze.mk to be updated, and thus have a
2367 newer time stamp again, which in turn makes a pristine CVS
2368 checkout have correct time stamps.
2370 * Makefile.maint (cvs-sv): New macro, to be used..
2371 (config.guess-url_prefix, config.sub-url_prefix)
2372 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2373 point to CVS text checkout of Gnulib files.
2374 (copyright-check): Bump current year.
2375 (announcement): Do not hard-wire `./announce-gen'.
2376 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2377 correctly.
2378 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2379 `chmod +x'.
2380 (wget_files): Update config.guess, config.sub, texinfo.tex by
2381 `wget-update', now that their URLs work again.
2383 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2385 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2386 Problem noted by Paul D. Smith.
2388 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2390 * doc/autoconf.texi: Remove unused words from word list.
2391 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2392 .x-sc_trailing_space: New files.
2394 * doc/standards.texi: Sync from gnulib.
2396 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2397 `LIBOBJDIR' as experimental.
2399 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2400 with a target directory; it's internally implemented as `cp'
2401 anyway, but since Autoconf advertises the possibility to use
2402 a target directory when LN_S is `ln -s', we need to find out.
2403 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2404 analyzed by Keith Marshall <keith.marshall@total.com>.
2406 * THANKS: Update.
2408 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2410 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2411 confdefs.h as-is. In general, if it has backslash-newline or the
2412 like, then it doesn't work either to sort or to remove empty
2413 lines.
2415 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2417 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2419 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2421 * lib/autom4te.in (Automake-preselections): Preselect
2422 _AM_SUBST_NOTMAKE.
2424 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2426 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2427 apostrophe within a single-quoted string, as this is the usual
2428 tradition and is easier to read than '"'"'. Don't rely on the
2429 shell treating "$/" like '$/'. Use a more-consistent indenting
2430 style for the trap.
2432 2006-04-09 Eric Blake <ebb9@byu.net>
2434 * tests/autotest.at (Backquote command substitution),
2435 (Multiline backquote command substitution): Remove mistaken
2436 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2437 applied...
2438 (Parenthetical command substitution, Multiline parenthetical
2439 command substitution): here.
2441 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2443 Import macros from gnulib (often changing their name).

2457 (Pointers): Add Gnulib URL.
2458 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2459 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2460 Gnulib section.
2461 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2462 suggest a #define rather than a typedef for _Bool, and mention
2463 Gnulib rather than trying to substitute stdbool code.

2465 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2466 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

2469 headers too.
2470 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
2471 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2472 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2473 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2474 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2475 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2476 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2477 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2478 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2479 (Coding Style). Don't mention m4_expand_once.
2480 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2481 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2482 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
2483 (AC_CHECK_FUNCS): Use it.

2488 (AC_HEADER_ASSERT): New macro.
2489 (AC_HEADER_STDBOOL): Don't assume "#error" works.
2490 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2491 Catch a bug in an HP-UX C compiler.
2492 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2493 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
2494 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
2495 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):

2497 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2498 New macros.
2500 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2501 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2503 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2505 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2506 of the warning introduced by the 2001-08-28 change.
2508 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
2509 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2511 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
2512 variables shall be overriden by the cache.
2513 * tests/torture.at (AC_ARG_VAR): Test also with a first value
2514 that contains braces.
2516 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2518 Revert the patch from 2006-04-01 and only improve
2519 _AS_DETECT_BETTER_SHELL:
2521 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2522 skip nonexistent directories.
2523 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2524 only shell candidates which exist.
2525 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2526 * lib/autotest/general.m4 (AT_INIT): No need to give three
2527 parameters to _AS_PATH_WALK.
2529 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2530 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2532 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2533 distinguish m4sugar macros.
2534 * tests/tools.at (autoupdating with aclocal and m4_include):
2535 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2536 test case by Noah Misch <noah@cs.caltech.edu>.
2538 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2540 Revert my change from 2006-03-17, in other words:
2541 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2542 and DUALCASE=1.
2543 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2544 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2545 it is set.
2547 2006-04-07 Eric Blake <ebb9@byu.net>
2549 * doc/autoconf.texi (Programming in M4sh): Document that
2550 AS_MKDIR_P exits the script on failure.
2551 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2553 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2555 * config/elisp-comp, config/install-sh, config/mdate-sh,
2556 config/missing, config/mkinstalldirs: Sync from Automake.
2558 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2559 from Automake.
2561 * doc/make-stds.texi: Sync from gnulib.
2563 2006-04-06 Eric Blake <ebb9@byu.net>
2565 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2566 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2567 2006-04-01.
2569 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2570 Eric Blake <ebb9@byu.net>,
2571 Paul Eggert <eggert@cs.ucla.edu>,
2572 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2574 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2575 whether `set' quotes correctly: redirect stderr of the tested
2576 `set', and use a subshell, for Ultrix; use `sed' instead of
2577 `grep' for zsh `set' which may write binary output; match only
2578 at the beginning of a line, to avoid false positives.
2579 In order to avoid false positives by unrelated variables with
2580 multiline content, put the dump algorithm in a subshell and
2581 unset all variables containing newlines (except some which are
2582 special to the shell). Warn about cache variables that are
2583 unset.
2585 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2587 * config/config.guess, config/config.sub, config/texinfo.tex:
2588 Sync from upstream.
2590 * tests/mktests.sh: Reword comments.
2592 * tests/mktests.sh: Only skip internal macros starting with
2593 `_AC_' or `__AC_'. Noted by Stepan Kasal.
2594 Update exclusion lists for the test suite to this end:
2595 (AC_ARG_VAR): Do test this now.
2596 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2597 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2598 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2599 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2601 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2602 shell issue with double-quoted command substitutions of native
2603 commands.
2604 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2605 Marshall.
2607 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
2608 no file matches the glob, discard the warning, set `nullglob'.
2609 (syntax-check): Likewise.
2610 (sc_cast_of_x_alloc_return_value): Likewise.
2611 (sc_cast_of_alloca_return_value, sc_error_exit_success)
2612 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
2613 (m4-check): Likewise.
2614 (sc_system_h_headers): Do not print rule on execution.
2615 (sc_tight_scope): Do not fail for non-existing `src' directory.
2616 (sc_changelog): Skip the Copyright footer.
2617 * lib/autoconf/lang.m4: Remove trailing space.
2619 * lib/autoconf/status.m4: More replacements to
2620 <tab><space> where this makes sense.
2622 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2624 * tests/Makefile.am (maintainer-check-posix):
2625 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2627 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2628 ac_config_<foo>s again, sometimes normalized, sometimes not.
2629 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2630 (AC_CONFIG_COMMANDS): Do not do so here.
2631 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2632 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2633 2005-07-25 rewrite. Noticed by Noah Misch.
2635 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2636 _AC_PRESERVE_HELP_ORDER, ...
2637 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2639 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2640 inside m4_expand_once; it is redundant.
2642 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2643 for --help from Cygnus `configure.'
2645 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
2647 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
2648 on a patch proposed by Ralf Wildenhues.
2650 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2652 * lib/autoconf/status.m4: Replace <space>''<tab> with
2653 <tab><space> where this makes sense.
2655 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
2656 Noah Misch <noah@cs.caltech.edu>
2658 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2659 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2660 * doc/autoconf.texi (Help Formatting): New node.
2661 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2663 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2665 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
2666 lib/autoconf/specific.m4, lib/autoconf/status.m4,
2667 lib/autoconf/types.m4, lib/autotest/general.m4,
2668 tests/mktests.sh, tests/torture.at: White space cleanup:
2669 remove some SPACE before TAB, or add quoting ('' or @&t@).
2671 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
2673 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
2675 2006-04-05 Eric Blake <ebb9@byu.net>
2677 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2678 empty test suite works.
2679 * tests/autotest.at (Empty test suite): Remove xfail.
2681 2006-04-05 Noah Misch <noah@cs.caltech.edu>
2683 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
2684 TAGS to ac_config_<foo>s.
2685 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2686 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2687 normalizing it, consistent it with previous releases.
2688 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
2690 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2692 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
2693 Use simplified args that Eric Blake originally suggested.
2695 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
2697 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
2698 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2699 Use 'comm' rather than N instances of grep; this also fixes a bug
2700 whereby substrings were incorrectly matched, causing us to not
2701 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2702 (exclude_list): Exclude empty macros.
2703 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

2708 Switch from grep to awk syntax.
2709 (ac_exclude_script): Renamed from ac_exclude_egrep.
2710 (au_exclude_script): Renamed from au_exclude_egrep.

2788 ac_file to the name of the default output file and call
2789 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2790 initial `rm' of the candidate files...
2791 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2792 the same list in subsequent `rm' calls, and for the temporary
2793 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2794 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2795 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2796 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or

2838 subordinate tools.
2839 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
2840 * doc/autoconf.texi (autoreconf Invocation): Document it.

2876 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
2877 switch all of them on and of when necessary. Fixes the bug when
2878 m4sugar macros (e.g., m4_define) were expanded after the first
2879 automatic update (e.g., after AC_PREREQ or AC_INIT).
2881 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

3053 Update and fix the documentation accordingly.
3054 * tests/autotest.at (Keywords): Renamed to..
3055 (Keywords and ranges): .. this. Extended to make sure negated
3056 keywords, keywords taken from AT_SETUP arguments, and numeric
3057 test ranges work, and that matching is case-insensitive.

3076 trying to execute the command `no'.
3078 * lib/autoconf/lang.m4 (AC_LANG_CONFTEST): AC_DEFUN this, not
3079 m4_define, so that the requirements of `AC_INCLUDES_DEFAULT' are
3080 expanded outside.

3083 example. Do not emphasize `$%', it is hardly new and special.
3084 Reported by Edouard Bechetoille <ebecheto@ens-lyon.fr>.
3086 * doc/autoconf.texi (Limitations of Usual Tools): Document
3087 OpenBSD and traditional `grep' failure to handle multiple

3114 the obsolescent AC_HEADER_STDC.
3115 (AC_FOO_IFELSE vs AC_TRY_FOO): Don't use #error; test programs
3116 can't rely on it.
3118 2006-03-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3120 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):

3125 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
3126 Require that /lib/cpp include stdio.h correctly. Solaris 10's
3127 doesn't. Problem reported by D'Arcy A MacIsaac and diagnosed by
3128 Ralf Wildenhues.
3130 2006-03-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3133 HP-UX sed is 99 commands, not 100.
3134 (_AC_OUTPUT_FILES_PREPARE): Do not count the `}' of an
3135 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
3136 newline for portability.
3137 * tests/torture.at (Torturing config.status): Also test 100
3138 AC_SUBST_FILE invocations. Fix test to actually verify the

3619 (which belong to Xt, not X itself). See Debian bug 327655.
3620 * NEWS: Mention this.
3622 2005-09-07 Stepan Kasal <kasal@ucw.cz>
3624 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
3626 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
3628 * config/move-if-change: Don't output "$2 is unchanged";
3629 suggested by Ben Elliston. Handle weird characters correctly.
3631 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3633 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3634 calls, so that the final expansion of this macro is shorter.
3635 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3636 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3637 the cleanup there. Use AS_VAR_* macros, to be more general.
3638 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3640 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3642 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
3644 2005-09-01 Stepan Kasal <kasal@ucw.cz>
3646 * doc/autoconf.texi (Configuration Headers): Add an index entry
3647 for AH_HEADER.
3649 2005-08-26 Pavel Roskin <proski@gnu.org>
3651 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
3652 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
3653 running xmkmf.
3655 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
3657 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3658 The previous patch didn't work, so try a better one.
3660 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3662 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3663 in the example. Reported by Bruno Haible.
3664 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3665 "if $undefined_var;" succeeds with my shell.
3667 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3668 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3669 but change the m4_divert_text to m4_divert_once.
3671 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3673 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3674 Work around bug in Solaris /usr/xpg4/bin/awk.
3675 The bug is present in at least Solaris 8 through 10.
3677 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3679 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3680 some evil values and relying on the fact that $* concatenates the
3681 parameters by the first character from IFS.
3683 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3684 Stepan Kasal <kasal@ucw.cz>
3686 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
3687 first header appears, define AH_HEADER.
3688 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
3689 Update limitations about when to call AC_CONFIG_HEADERS.
3690 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3691 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3692 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3693 ``Configuration Actions''; fix their index entries.
3695 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3696 options correctly. Process N-M as M-N if M is smaller than N.
3697 Process ranges correctly so that N-N will run only N.
3698 Sort and uniquify the tests that will be run. If there is more
3699 than one test, reinsert the banners for the tests.
3700 * tests/autotest.at (Keywords): Unmark XFAIL.
3702 2005-08-23 Stepan Kasal <kasal@ucw.cz>
3704 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
3705 before passing the macro name to AH_TEMPLATE.
3707 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3708 now opens log after option processing; in particular, --version
3709 and --help do not touch config.log.
3711 * Makefile.maint: Revert the change from 2005-08-12.
3713 2005-08-22 Stepan Kasal <kasal@ucw.cz>
3715 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
3716 common code to...
3717 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.

3721 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
3722 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
3723 Language cleanup.
3725 * doc/autoconf.texi (Defining Symbols, Changed Results):
3726 Prepend to LIBS, not append, in examples.
3728 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3730 When building in place, set srcdir="."; suggested by Tim Van Holder.
3732 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3733 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3734 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3735 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3736 does not mean "no --srcdir option".
3738 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3740 * tests/autoscan.at (autoscan): New file.
3741 * tests/suite.at: Use it.
3742 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
3743 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
3745 * tests/autotest.at (Keywords): Test keywords combinations.
3747 2005-08-12 Stepan Kasal <kasal@ucw.cz>
3749 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
3750 add "2>&1"; gzip 1.2.4 prints help on stderr.
3752 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3754 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
3755 was pushdef'ed twice while popped only once. Push it only once.
3756 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
3758 2005-07-26 Stepan Kasal <kasal@ucw.cz>
3760 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

3765 * Makefile.maint: Update from Bison.
3767 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3768 "<tab>" in comment, so that the point is understandable.
3770 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3772 Rewrite substantial part of lib/autoconf/status.m4.
3773 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3774 and CONFIG_COMMANDS are not processed in four separate loops.
3775 Instead, there is one main loop. This alows that the common code
3776 is expanded only once, thus config.status (and configure) is smaller.
3778 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3779 the AC_LIST_FILES and cousins macros are no longer used.
3781 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3782 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3783 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3784 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3785 contain the initialization, nor the for loop, nor the associated
3786 commands; all these go to ...
3787 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3788 _AC_OUTPUT_CONFIG_STATUS.
3789 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3790 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3791 (_AC_OUTPUT_FILE): The creation of the sed script ...
3792 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3793 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3794 _AC_OUTPUT_MAIN_LOOP.
3795 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3796 _AC_CONFIG_COMMANDS): Use ...
3797 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3798 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3799 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3800 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3801 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3802 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3803 ... new macros.
3804 (_AC_CONFIG_UNIQUE): Update.
3805 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3806 Replaced by this ...
3807 (_AC_LIST_TAGS): ... new common macro.
3808 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3809 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3810 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3811 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3812 this didn't belong to the `config commands' section.
3813 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3814 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3815 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3816 to the `config commands' section either.
3817 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3818 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3820 ... and many changes to the comments nearby.
3822 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3823 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3824 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3825 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3826 (#define header templates): The comment at the top of the generated
3827 header now includes the name(s) of the source file(s).
3829 Several unrelated small changes:
3831 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3832 parameter to AC_DIAGNOSE.
3833 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3834 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3835 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3836 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3837 with AU::AC_OUTPUT.
3838 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3839 in AC_OUTPUT doesn't double-quote it either.
3840 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3841 parameters.
3843 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3845 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3846 versions of Portland Group compiler produce single- and double-quoted
3847 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3848 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3850 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3852 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3853 This is a corrected version of yesterday's patch.
3855 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3857 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3858 path, too; insert a "===" to emphasize the line.
3860 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3861 ac_cv_build_alias to ac_build_alias.
3862 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3864 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3865 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3866 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3867 (AC_ARG_VAR): ... here.
3868 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3869 target_alias.
3871 Keep a list of all precious variables and process them with one simple
3872 for loop, instead of expanding all commands, or, OTOH, complicated
3873 processing of output of "set".
3874 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3875 variable names in new macro...
3876 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3877 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3878 a loop to assign all ac_env_* and ac_cv_env_* variables.
3879 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3880 to INIT_PREPARE.
3881 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3882 its value to shell variable ac_precious_vars and call
3883 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3884 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3885 _AC_ARG_VAR_VALIDATE.
3887 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3888 and the AC_SUBSTs ...
3889 (AC_INIT): ... here.
3891 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3892 the ac_subst_files section in config.log.
3894 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
3896 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
3898 * NEWS: New macro AC_C_TYPEOF.

3901 * tests/c.at (C keywords): Test AC_C_TYPEOF.
3903 Fix problems reported by Nicolas Joly.
3904 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3905 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3906 They are generated by the Tru64 v5.1B shell.
3908 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3910 Fix my changes from 2005-07-01; reported by Noah Misch.
3911 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3912 description, the macro now accepts only a single tag.
3913 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3915 Fix cases when the varsions of Autoconf and Autotest don't match.
3916 Reported by Noah Misch.
3917 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
3918 at_top_builddir, for compatibility with older autotest.
3919 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3920 is not set, use at_top_builddir, for compatibility with older
3921 versions of autoconf.
3923 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3925 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3926 Problem reported by Patrick Welche.
3928 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3930 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3931 sed substitution command, so that we allow | in program prefixes
3932 and program suffixes. (& is a problem anyway; we're not fixing
3933 that here.)
3934 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3935 configure_input, top_builddir, srcdir, etc.
3936 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3937 PATH_SEPARATOR in AUTOTEST_PATH.
3939 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3941 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
3942 for loop over config.site files using `set', to allow
3943 directory names containing IFS characters.
3945 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
3947 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3948 directories with weird names. Apparently some people like living
3949 on the edge. However, improve the test that "pwd" actually does
3950 report a name for the working directory.
3951 * NEWS: Remove the claim that we test for funny chars in dir names.
3953 2005-07-01 Stepan Kasal <kasal@ucw.cz>
3955 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's

3965 about #include <config.h>.
3966 (Generic Functions): Mention the Gnulib project.
3967 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
3969 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3970 document to output the default config_* lists to config.status.
3971 Don't recognize option --file, if the functionality is not there.
3972 Likewise for --header; moreover, recognize --he and --h as shortcuts
3973 for --help in that case.
3975 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3976 matches the order of execution. No code changed.
3978 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3980 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for

3997 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
3998 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3999 (AC_SUBST): Call it.
4000 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4001 the directory specific variables; but don't call it for configure_input.
4003 2005-06-28 Derek Price <derek@ximbiot.com>
4005 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4006 addition.
4008 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4010 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4011 directory have inherent problems with special characters like spaces,
4012 due to limitations in Make syntax. Problem reported by Alexandre
4013 Duret-Lutz.
4014 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
4015 Also, fix Tru64 porting problem with shell patterns,

4026 Fix some more shell quoting problems. Prompted by a bug report
4027 from Justace Clutter.
4028 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4029 variable into diagnostic. Make the diagnostic an error, not a warning,
4030 because we really don't support spaces and suchlike in dir names.
4031 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4032 Don't worry about backslashes in srcdir; it can't happen now.
4033 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4034 Simplify ac_optarg handling.
4035 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4043 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4045 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4046 that '\|' is not allowed in BREs; recommend using newline separated
4047 list of patterns instead of multiple -e options.
4049 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4051 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.
4053 2005-06-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4055 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Fix typo.
4057 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4059 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4060 b, t, r, w commands require single space, while : cannot have any.
4061 (Special Shell Variables): Fix sed code this in the example.
4062 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4063 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4065 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4066 expand to the empty list. Don't use two pairs of m4_changequote,
4067 it's not necessary.

4073 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4075 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4076 * doc/autoconf.texi:
4077 Don't mention Solaris versions so much, if a
4078 problem is common to all extant versions of Solaris. Say "SunOS
4079 4" instead of "SunOS" for SunOS 4.
4080 (awk): Mention more of the limitations of traditional Awk.
4081 (cat): Don't talk about cat -v.

4086 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
4087 but the implementation is entirely different and is designed
4088 to be compatible with glibc strverscmp.
4089 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4091 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4092 on Mac OS X 10.4 reported by Peter O'Gorman in:
4093 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4094 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):

4106 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4108 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4109 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4110 to update the man page. That way, we don't have to check in new
4111 man pages every month.
4113 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4114 quotes and backslashes. Patch from Derek Price.

4123 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4124 -u, since it outputs chatter if the input files are the same.
4125 Problem reported by Ralf Menzel.
4127 2005-06-08 Derek Price <derek@ximbiot.com>
4129 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4130 renaming them since they are about to be redefined anyhow.
4132 2005-06-08 Derek Price <derek@ximbiot.com>
4134 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4135 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4136 Move m4_undefine to alphabetical order.
4138 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4140 * README: Recommend GNU M4 1.4.3 or later.
4141 * doc/autoconf.texi (Introduction): Likewise.
4142 Reword to avoid some formatting glitches.
4143 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4144 Clarify explanation of HP compiler bug.
4145 Redo example output tp match current CVS snapshot.
4146 Use @example.org in email addresses when the examples
4147 might get inadvertently cut-and-pasted into user code.
4148 Remove example of autom4te usage that doesn't seem to work now.
4149 Use modern AC_INIT (except when the example is meant to be
4150 shown with Autoconf 2.13).
4151 Update ksh info for Solaris 9 and later.
4152 KB -> kB.
4153 Modernize description of Automake versions a bit.
4154 Don't claim a future version of Autoconf is near.

4160 follows its own advice about quoting better.
4161 Reword to avoid some formatting glitches.
4162 * doc/installt.exi: Reword to avoid some formatting glitches.
4164 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4165 Tru64 ksh pattern matching bug. Reported against Libtool by
4166 Albert Chin <libtool@mlists.thewrittenword.com> and
4167 Nicolas Joly <njoly@pasteur.fr>.
4169 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4171 m4_cdr of one-member list was [[]] (one-member list containing an
4172 empty string) instead of [] (an empty list. Callers were skewed to
4173 match this misbehaviour. As a consequence of this:
4174 - m4_foreach([x], [], [foo]) expanded to `foo', while
4175 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4176 This bug has been fixed:
4178 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4179 expand to an empty string; print error msg if called without
4180 an argument list.
4181 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4182 misbehaviour; handle [] and [[]] correctly.
4184 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4186 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

4188 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4190 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4192 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4193 swallow records with more than 99 fields.
4194 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4195 parse the long line.
4197 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4199 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4200 swallow literals longer than 399. Reported by Ralf Wildenhues.
4201 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4202 to workaround this limitation.
4204 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4206 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4207 to gfortran, and make these the first two compiler names
4208 checked (following the general autoconf preference for gcc).
4210 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4212 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4213 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4214 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4216 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4218 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4219 expression of unbounded size when processing the --list
4220 option. This runs afoul of a limit of 399 bytes per regular
4221 expression on AIX. Problem reported by Ralf Wildenhues.
4223 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4225 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4226 * doc/autoconf.texi (Particular Headers): Reword example
4227 for multiline stdbool replacement.
4228 (Setting Output Variables): Reword text a bit. Don't
4229 give all the details about |#_!!_#|.
4230 Reword description of line replacement.
4232 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4234 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4235 now contain newlines, and substituted files must be referenced on
4236 a line alone; the sed scripts to substitute them are now very
4237 different.
4238 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4239 commands can be put in a sed script portably.
4240 * doc/autoconf.texi (Setting Output Variables): Document above
4241 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4242 use of multiline substitution.

4252 * tests/local.at: Don't attempt to check for negated character
4253 classes in shell scripts. The test was too brittle.
4255 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4257 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4258 * doc/autoconf.texi (Limitations of Builtins): Document this
4259 limitation.
4261 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4263 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4264 common code; used in many places in the tree.

4271 messages when ac_unique_file is not found.
4272 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4273 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4274 commands, for consistency with AC_MSG_ERROR and such.
4276 * bin/autoconf.as: Make more use of "shift 2" in option processing.

4286 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4288 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4289 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4290 (ac_top_builddir): ... this ...
4291 (ac_top_build_prefix): ... to this; the old name is also kept, for
4292 backward compatibility.
4293 (ac_top_builddir_sub): New variable, without the trailing slash,
4294 always nonempty.
4295 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4296 * doc/autoconf.texi (Configuration Actions): Rename
4297 ac_top_builddir to ac_top_build_prefix.
4298 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4299 at_top_builddir to at_top_build_prefix.

4305 of confdefs.h .
4307 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4309 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4310 argument to m4_foreach. I guess it was necessary in the past,
4311 but I think it's a no-op now.
4313 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4315 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4316 ``cat <<_ACEOF'' commands to one.
4317 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4318 * lib/autoconf/status.m4: On various places, use expr instead of
4319 ``echo|sed.''
4320 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4321 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4322 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4323 a range.
4324 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for

4330 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4331 as on 2005-05-02.
4332 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4333 Mention LIBOBJDIR.

4396 Also, throughout this document, be more careful about white space.
4397 "blank", "white space", and "space" all have different meanings
4398 and we should be careful to say what we mean.

4519 * doc/autoconf.texi (Installation Directory Variables): Allow
4520 "," in file names. Do not use \@; it's not a portable regexp.
4521 * bin/Makefile.am (edit): Likewise.
4522 * lib/Makefile.am (edit): Likewise.
4523 * tests/Makefile.am (edit): Likewise.

4528 * doc/autoconf.texi (File System Conventions): Warn about
4529 unportable file names.
4530 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4531 (AC_INIT): Use it.
4532 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4533 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4534 ac_pwd, and quote srcdir.
4535 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4537 * doc/autoconf.texi: Fix some systematic formatting problems.
4538 ".)" needs a following @: if not at the end of a sentence, and
4539 similarly for "!)". "etc." should be preceded by a comma.
4540 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4542 2005-03-22 Bruno Haible <bruno@clisp.org>
4544 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4545 argument is often called 'build-aux'.
4547 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4549 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4550 macro AC_TRY_LINK is obsolete.
4551 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4552 `AC_CONFIG_FILES'.
4554 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4556 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4557 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4558 from a Common Lisp's `cl'.
4559 (AC_PROG_CXX): Behave according to the documentation: don't
4560 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4561 make the variable CCC precious; use `cl.exe', not `cl'.
4563 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4564 Alexandre Duret-Lutz <adl@gnu.org>
4566 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4567 /dev/null, as "configure" shouldn't read stdin, and this insulates
4568 us from problems (e.g., when testing for "cl"). Also, do this
4569 redirection before invoking "hostname" or "uname", and keep the
4570 original input stream available via...
4571 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4572 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4573 bother with "</dev/null" since it's now done at the top of
4574 'configure'.
4575 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4576 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

4582 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4584 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4585 newline if neither \c nor -n work, as that would output two
4586 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4588 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4590 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4591 This causes that any required macros inside will get before the if.
4592 * doc/autoconf.texi (autom4te.cache): A typo.
4594 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4596 Undo previous change, except keep the change to
4597 lib/autoconf/programs.m4 that replaced grep with shell
4598 pattern-matching. This is because net-snmp configure reads stdin.
4599 Reported by Noah Misch.
4601 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4603 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4604 from /dev/null, as "configure" shouldn't read stdin, and this
4605 insulates us from problems (e.g., when testing for "cl").
4606 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4607 before invoking "hostname" or "uname".
4608 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4609 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4610 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4611 "</dev/null" since it's now done at the top of 'configure'.
4612 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4613 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4614 Also, replace grep with shell pattern-matching, to save a process.
4616 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4618 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4619 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4620 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4621 compiler.
4623 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4625 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4626 grep -q isn't portable. Improve grep -s explanation.
4627 Problem reported by Dan Manthey.
4629 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4631 * doc/autoconf.texi (Special Shell Variables): Clarify
4632 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4634 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4636 * doc/autoconf.texi: Use @acronym for DJGPP.
4637 Fix some @code's that should have been @env's, and vice versa.
4638 Sort environment variable names.
4639 Mention that shells no longer inherit IFS.
4640 Don't recommend PATH_SEPARATOR=';' so strongly.
4641 Mention that $RANDOM might expand to the empty string.
4642 "symlink" and "soft link" -> "symbolic link".
4643 Improve mktemp description (reported by Bruno Haible).
4645 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4647 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4648 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4649 Likewise.

4655 * NEWS: Mention AT_COPYRIGHT.
4657 * tests/local.at (AT_CMP): Use diff directly on input files rather
4658 than copying them.
4660 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4661 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
4663 2005-02-04 Noah Misch <noah@cs.caltech.edu>
4664 and Paul Eggert <eggert@cs.ucla.edu>

4673 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
4674 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
4675 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.

4677 (Standard regular expressions): New test.
4678 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4679 excess test name quoting.
4680 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4681 CPPFLAGS to `configure' instead of setting it in `configure'.
4683 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4684 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4685 on some platforms.
4687 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4688 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

4691 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.

4696 * tests/c.at (Extensions): Do not exit early.

4716 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4718 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4719 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4721 Try not to generated lines of unlimited length, as POSIX places a
4722 2047-byte limit on line length of portable text files.
4723 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4724 Use newline as a separator, not space.
4725 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4726 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4727 space.
4729 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4731 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4732 as_func_*. Add test to check whether positional parameters
4733 are restored after function return.
4735 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4737 * doc/autoconf.texi (Special Shell Variables): Mention _,
4738 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4739 if they contain a lower-case letter. The DUALCASE problem was
4740 reported by Ralf Wildenhues.
4742 * bin/autoconf.as: Don't exit with status 0 after write failure
4743 with --help or --version.

4755 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4757 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4758 care to echo the commands, so the user knows what's going on.
4759 Modified from a suggestion by Stepan Kasal.
4761 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

4769 Based on a proposed patch by Ralf Wildenhues.
4771 * man/Makefile.am (.x.1): Make sure the required generated files
4772 are up to date. Problem and original solution proposed by Stepan Kasal.

4780 2005-01-29 Stepan Kasal <kasal@ucw.cz>
4782 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4783 Update the long comment explaining it.
4785 m4_require no longer writes an ``is required by'' line to the
4786 execution stack. It contains only one bit of non-redundant
4787 information: that the macro was required, not called. And even
4788 this bit is useless in most situations: have you ever met a macro
4789 which both calls and requires the same macro?
4791 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4792 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4793 macro.
4794 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4795 (m4_expansion_stack_pop): Remove the misplaced comment.
4796 (m4_require): Don't put the ``is required by'' line to the
4797 execution stack; slightly improve the out-of-a-defun error message.
4798 (_m4_divert_grow): New macro, counter for the temporary diversions.
4799 (_m4_require_call): Use it.
4800 * tests/m4sugar.at (m4_require): Expect output without the
4801 ``is required by'' messages.
4803 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4805 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4806 rather than x for expr.
4808 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4809 this is safe.
4810 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4811 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4821 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
4822 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4823 from masters, so that FileUtils.pm's update_file provide --force
4824 support.
4825 * bin/autoheader.in: Pass $force to update_file so that
4826 config.h.in is always recreated when --force.
4828 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4830 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4832 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4834 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4835 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4837 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4839 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4840 Warn about newline stripping in `` and $(). Update Solaris
4841 version to 9.
4842 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4843 X insulates us from future changes to Posix.
4844 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4845 stripping.
4847 2005-01-19 Stepan Kasal <kasal@ucw.cz>
4849 * doc/autoconf.texi (Defining Symbols): Delete the false comment that

4865 ulongval to be static, to avoid unwanted GCC warning. Problem
4866 reported by Michael Jennings via Daniel Reed; see
4867 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4869 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4871 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

4873 datadir, infodir, and mandir. Adjust argument parsing code.
4874 (_AC_INIT_HELP): Update help text.

4876 new variables.
4878 2005-01-04 Noah Misch <noah@cs.caltech.edu>
4880 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
4881 not seem to work, assume it does set $(MAKE).

4884 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4886 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

4892 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
4893 (_m4_divert_n_stack): New macro; the expansion is
4894 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4895 otherwise.
4896 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4897 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4898 stored in _m4_divert_diversion or _m4_divert_dump.
4899 (m4_divert_pop): When the parameter is given, compare the symbolic
4900 name with the last diversion pushed on the stack. Previously, the
4901 current diversion was compared with the numeric value of the
4902 diversion given as the parameter.
4903 (m4_require): If the macro hasn't been expanded yet, call ...
4904 (_m4_require_call): this new macro.
4906 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

4937 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
4938 signals that the package uses Automake; a `Makefile.am' is typical but
4939 not essential. Reported by Magnus Therning.
4940 * tests/torture.at (autoreconf.): New banner.
4941 (autoreconf and non-AC configure): Rename to `Non-Autoconf
4942 AC_CONFIG_SUBDIRS'.

5211 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5212 "char c = '\200';" rather than "char c = 0x80;" as the

5330 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns

5422 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5424 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5426 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5427 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5428 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5430 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5432 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5433 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5434 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5435 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5436 * lib/autom4te.in (Automake-preselections): Preselect
5437 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5439 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5441 * lib/autom4te.in (Automake-preselections): Preselect
5442 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5443 trace them.
5445 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5447 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5448 Tru64.
5449 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5450 Document problem with "`""`" in pdksh POSIX mode.
5452 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5454 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5455 with pdksh, too. Problem reported by Patrick Welche via
5456 Gary V. Vaughan.
5457 * doc/autoconf.texi (Shellology): Note that set -o posix is
5458 useful for pkdsh, too.
5460 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5462 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5463 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5464 Don't fail if ENV or BASH_ENV is readonly.
5465 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5466 etc. are read only. Problem reported by Ludovic Courtes.
5468 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5470 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5471 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5472 (trivial change)
5474 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5476 * doc/autoconf.texi (File System Conventions): Warn about
5477 names like "aux". Problem reported by Eric Blake.
5479 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5480 by zero instead of array size, so that we can use any arithmetic
5481 constant expression (instead of requiring an integer constant
5482 expression). This allows us to test expressions like DBL_MAX <
5483 LDBL_MAX, which didn't conform to the C standard using the old
5484 method.
5485 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5486 now that we can do floating-point tests at compile time.
5488 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5490 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5491 and LDBL_EPSILON, as the resulting expression isn't an
5492 integer constant expression and violates the C standard.
5493 Problem reported by Nelson H. F. Beebe. Also, check
5494 for "L" suffix, and check that long double doesn't have
5495 worse range or precision than double, that mixed-mode
5496 arithmetic doesn't generate a diagnostic, that double
5497 constants fit in long double.
5499 2004-06-03 Kevin Ryde <user42@zip.com.au>
5501 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5502 malloc(0) and realloc(NULL,size).
5504 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5505 Bob Proulx.
5507 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5509 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5510 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5511 by Jim Meyering.
5513 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5515 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5516 can be rewritten using if-then-else. Suggested by Bruno Haible.
5518 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5520 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5521 Problem reported by Stepan Kasal.
5523 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5525 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5526 change). Patch reported by Ralf Wildenhues in
5527 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5529 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5530 function F exists if the compiler and linker let you compile an
5531 expression like (F != 0). Recent versions of GCC optimize away
5532 the reference to F in that case, since every function address must
5533 be nonzero, so the link succeeds even if F does not exist.
5534 Problem reported by Manu in
5535 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5537 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5538 "Unix". Many uses changed.
5539 (Limitations of Builtins): Explain better why the ! command isn't
5540 portable.
5542 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5544 * lib/autom4te.in (Automake-preselections): Preselect
5545 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5547 2004-05-19 Kevin Ryde <user42@zip.com.au>
5549 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5550 referencing AC_FUNC_STRERROR_R.
5552 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5553 note pessimistic assumption when cross compiling.
5555 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5557 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5558 (until 2004) invoked subcommands with sh -e, contra POSIX.
5559 Reported by Kevin Ryde.
5561 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5563 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5564 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5565 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5566 `test -f " /usr/bin/grep"', which _always_ failed.
5567 (AC_PROG_SED): Ditto bogus PATH fix.
5568 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5569 requires that grep correctly supports _multiple_ `-e' options, rather
5570 than stating only that grep should accept `-e'.
5572 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5574 Port to C99, which requires that 'exit' be declared.
5576 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5577 to ensure that stdlib.h is included.
5578 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5579 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5580 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5581 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5582 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5583 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5584 when using 'exit' in a test; C99 requires that 'exit' be declared.
5586 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5588 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5589 now prefers 'grep' implementations that accept -e.
5590 (Limitations of Usual Tools): Describe problems of traditional
5591 egrep and fgrep with long input lines, and of traditional grep
5592 with -e.
5593 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5594 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5595 All callers changed. Append /usr/xpg4/bin to the PATH, for
5596 Solaris.
5597 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5598 the user with complaints about multiple -e options.
5599 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5600 Define it with AC_PROG_GREP.
5601 * configure.ac (AC_PROG_GREP): Add.
5602 * lib/freeze.mk (GREP): New macro.
5604 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5606 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5607 a possible candidate only after all others fail, rather than
5608 consulting it first. This improves backward compatibility by
5609 better reflecting the way shell selection occurred in previous
5610 versions of Autoconf, and should help to avoid triggering latent
5611 problems in other packages, such as the one in Automake where zsh
5612 is not handled robustly:
5613 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5614 Although it is not Autoconf's responsibility to work around
5615 problems in Automake, it nevertheless makes sense to avoid
5616 introducing unnecessary incompatibilites.
5618 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5619 Gary V. Vaughan <gary@gnu.org>
5621 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5622 how deeply nested we are when a suitable tool is found, set the
5623 ac_path_TOOL_found flag.
5624 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5625 nested we are in this macro. Break out of all 3 nested loops if
5626 ac_path_TOOL_found is set.
5628 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5630 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5631 of the _AS_PATH_WALK loop too if GNU flavor is found.
5633 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5635 * doc/autoconf.texi (Limitations of Make): Update documentation
5636 for `$<'. New entry `Long lines', based on a report from Simon
5637 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5638 paragraph about DJGPP, based on a mail from Richard Dawe.
5640 2004-04-20 Paul Eggert <eggert@twinsun.com>
5642 * tests/c.at (C keywords): Don't assume that GCC supports
5643 "restrict" and "inline", as sufficiently-old GCC versions do not
5644 (also, GCC configured to be in pedantic C89 mode does not).
5645 Problem reported by Sumit Pandya in:
5646 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5648 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5649 consider -g to work if it generates warnings when plain compiles
5650 don't. Problem reported by Braden McDaniel in:
5651 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5653 * doc/autoconf.texi (Slashes): New section, to document a problem
5654 reported by Jim Meyering in:
5655 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5657 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5658 linker output files before linking, to work around IRIX 6 linker bug.
5659 Problem reported by Rainer Orth in:
5660 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5662 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5664 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5665 best tool so far counter rely on the tool path variable name to
5666 avoid checks for one tool being affected by the results of running
5667 the length check on a previous tool.
5669 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5670 match expression argument, as different greps have different
5671 regular expression flavours.
5672 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5673 literals.
5674 (AC_PROG_EGREP): Pass 'EGREP$'.
5675 (AC_PROG_GREP): Pass 'GREP$'.
5677 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5679 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5680 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5682 2004-03-29 Paul Eggert <eggert@twinsun.com>
5684 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5685 Types, Specific Compiler Characteristics, System Services,
5686 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5687 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5688 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5689 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5690 Likewise.
5691 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5692 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5693 AC_TYPE_OFF_T): Likewise.
5694 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5695 Likewise.
5697 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5698 pacify libtool 1.5.2. Fix quoting problems in sed command.
5700 2004-03-28 Paul Eggert <eggert@twinsun.com>
5702 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5703 now defines HAVE_DECL_TZNAME if it is declared, when
5704 HAVE_STRUCT_TM_TM_ZONE is not defined.
5705 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5706 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5707 for HAVE_TZNAME.
5709 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5711 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5712 superfluous backslashing of quotes (") in sed expressions;
5713 thanks to Paul Eggert.
5715 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5717 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5718 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5719 H. F. Beebe for the bug report.
5721 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5723 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5724 quoted -cmdline argument in Portland Group compiler (bug
5725 reported by Jeffrey J. Barteet).
5727 2004-03-25 Kevin Ryde <user42@zip.com.au>
5729 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5730 (Run Time): ... here, where it's now mentioned.
5732 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
5734 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
5735 inherits from language Autoconf-without-aclocal-m4.
5736 (Customizing autom4te): Adjust example; the cache must now be
5737 disabled for language Autoconf-without-aclocal-m4.
5739 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
5740 Nathanael Nerode <neroden@twcny.rr.com>

5747 * doc/autoconf.texi (Generic Programs): Document
5748 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
5749 AC_CHECK_TARGET_TOOLS, and warn for future changes
5750 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
5751 AC_CHECK_TOOLS.
5752 (Specifying Names): Document the reason for these future
5753 behavioral changes.
5754 * tests/mktests.sh: Do not generate tests for the
5755 new macros.
5756 * NEWS: Document these changes.
5758 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5759 they make TeX hang up.
5761 2004-03-15 Paul Eggert <eggert@bogus.example.com>
5763 * NEWS: New macro AC_CHECK_ALIGNOF.
5764 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5765 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5766 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5767 vowel.
5768 (AC_CHECK_ALIGNOF): New macro.
5769 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5770 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5771 those for sizeof.
5773 2004-03-03 Paul Eggert <eggert@twinsun.com>
5775 * bin/Makefile.am (edit): Don't use $< in a context where
5776 POSIX doesn't require support for it. Use $@.in instead.
5777 Problem reported by Anthony N. Frasso in
5778 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5779 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5781 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5783 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5784 from the next generation of Libtool.
5785 * lib/autom4te.in (Autoreconf-preselections): Ditto.
5787 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5789 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'

5792 2004-02-18 Paul Eggert <eggert@twinsun.com>
5794 Fix a dependencies problem, stemming from a Autoconf 2.59 build
5795 problem on QNX reported by Stephen Rasku in
5796 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
5798 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
5799 $(m4sh_m4f_dependencies); this removes a FIXME.
5800 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
5801 (MAINTAINERCLEANFILES): Split into pieces,
5802 one per related section. Add $(srcdir)/wrapper.in.
5804 2004-02-09 Paul Eggert <eggert@twinsun.com>
5806 * doc/autoconf.texi (Setting Output Variables): Emphasize that
5807 AC_SUBST provides no portable way to escape literal newlines.
5809 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5810 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5811 Darwin uses -lcrt2.o and there's little point to cataloging all
5812 the system variants. Partial fix reported by Andreas Waechter in:
5813 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5814 for bug reported by Nelson H. F. Beebe in:

5822 acobsolete.m4, suggested by Alexandre Duret-Lutz.
5824 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
5826 * bin/autoupdate.in: Define __file__ so that warnings
5827 refer to the correct file.
5828 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5829 the behavior of the third argument.
5830 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5831 correctly the behavior of the third argument. Document
5832 what the three macros that AU_DEFUN defines do. Fix
5833 warning message when the third argument includes $0
5834 (reported by Alexandre Duret-Lutz).
5836 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5837 Eric Sunshine <sunshine@sunshineco.com>
5838 Paul Eggert <eggert@twinsun.com>
5840 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5841 (AS_INIT): Output shell initialization there. Removed optional
5842 parameter. Expand _AS_SHELL_FN_SPY.
5843 (AS_INIT_WITH_SHELL_FN): Removed.
5844 (_AS_SHELL_FN_SPY): New macro.
5845 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5846 macros.
5847 (AS_SHELL_SANITIZE): Remove loop to find better shell
5848 and documentation for the parameter.
5849 (_AS_DETECT_BETTER_SHELL): Move it here.
5850 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
5851 (_AS_RUN): Move it here, support testing with eval.
5852 (AS_REQUIRE_SHELL_FN): Require shell functions when
5853 it is used.
5854 (_AS_LINENO_WORKS): Put around braces, we do not
5855 trigger the bash bug anymore.
5856 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
5857 use AS_INIT_WITH_SHELL_FN.
5858 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5860 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
5862 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
5863 * doc/autoconf.texi: Don't say that the third parameter
5864 is broken.
5865 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5866 (AU_DEFUN): Honor the third parameter, create autoupdate
5867 macros with AU_DEFINE.
5868 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,

5877 * lib/autoconf/status.m4: Remove FIXME.

5882 of autoupdate.

5888 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh

5890 the 2003-05-22 change, which removed the older years from the list.
5891 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5893 2004-01-27 Gary V. Vaughan <gary@gnu.org>

5898 possible.
5899 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5900 AC_PROG_GREP.
5901 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5902 egrep and fgrep respectively if $GREP -E/-F don't work.
5903 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5904 _AC_PROG_GREP, and AC_PROG_SED.
5905 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5906 longest input length accepted by a command.
5907 (AC_PROG_SED): Use it.
5908 * doc/autoconf.texi (Particular Programs): Document the changes.
5909 * NEWS: Updated.
5911 2004-01-27 Paul Eggert <eggert@twinsun.com>
5913 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

5915 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5916 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5918 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5919 bin/autoconf.in, config/Makefile.in, config/config.guess,
5920 config/config.sub, config/install-sh, config/mdate-sh,

5935 2004-01-26 Paul Eggert <eggert@twinsun.com>
5937 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5938 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5939 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5940 not <inttypes.h>. Problem reported by Tim Mooney in
5941 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5942 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5943 Likewise.
5945 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5946 otherwise "make check" fails because it forbids cmp (I guess
5947 because cmp treats files as binary on DOS-like systems).
5949 * tests/mktests.sh: Update copyright date to 2004, since some tests
5950 have changed in 2004.
5952 2004-01-23 Gary V. Vaughan <gary@gnu.org>

5955 non-truncating sed or gsed program in PATH.

5958 * NEWS: Updated.
5960 2004-01-15 Paul Eggert <eggert@twinsun.com>
5962 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5963 -std1 disables some useful extensions on Tru64. Problem reported
5964 by N. Lichtmaier in
5965 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5967 2004-01-14 Paul Eggert <eggert@twinsun.com>
5969 * doc/autoconf.texi (Programming in M4sh): Document that
5970 AS_MKDIR_P succeeds if the destination is a symbolic link
5971 to an existing directory.
5972 (Limitations of Usual Tools): Note that mkdir -p might not
5973 succeed on symlinks to directories.
5975 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5977 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5978 * bin/autoheader.in: Grammar fix in message.
5979 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5980 Test for dir before calling mkdir -p. (trivial changes)
5982 2004-01-13 Eric Blake <ebb9@byu.net>
5984 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5985 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5987 2004-01-10 Jim Meyering <jim@meyering.net>
5989 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5991 2004-01-09 Paul Eggert <eggert@twinsun.com>
5993 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5994 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5995 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5996 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5997 AC_COMPILE_IFELSE, since we now assume our caller invokes
5998 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5999 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6000 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6001 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6003 2004-01-07 Paul Eggert <eggert@twinsun.com>
6005 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6006 `"'...'"`, as it's confusing (and I suspect it may not work on
6007 some platforms). The code was incorrect anyway, as it assumed
6008 that \$ evaluated to itself in that context. Reported by
6009 Alexandre Duret-Lutz.
6011 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6013 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
6014 and _LT_AC_TAGCONFIG.

6018 * doc/autoconf.texi (One Macro Call): Fix an incorrect
6019 example, and add more examples. Reported by Eric Sunshine.
6021 2004-01-05 Paul Eggert <eggert@twinsun.com>
6023 * doc/autoconf.texi (Limitations of Usual Tools):
6024 Remove warning against "rm -fr" introduced yesterday; it
6025 was a false alarm.
6027 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
6028 autoscan, autoupdate, ifnames): Don't use chmod -w.
6029 * lib/Makefile.am (autom4te.cfg): Likewise.
6030 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
6031 "chmod -w".

6036 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts

6039 2004-01-04 Paul Eggert <eggert@twinsun.com>
6041 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6042 Use "rm -f" to remove conftest.sed, not plain "rm".
6043 Bug reported by David Relson in
6044 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6046 * Makefile.am (autom4te-update):
6047 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6048 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6049 * doc/autoconf.texi (Guidelines): Likewise.

6055 * tests/Makefile.am (clean-local): Likewise.
6056 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6057 srcdir): Likewise.
6058 * doc/autoconf.texi (Limitations of Usual Tools):
6059 Warn against "rm -fr".
6061 2004-01-03 Paul Eggert <eggert@twinsun.com>
6063 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6064 -c -o might not work. From a suggestion by Kevin Ryde.
6065 (C Compiler, Generating Sources, Limitations
6066 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6067 Don't put '-o' after non-options, as POSIX doesn't allow this.
6068 Mention that cc's name might be gcc or c89 or whatever.
6070 2004-01-04 Kevin Ryde <user42@zip.com.au>
6072 * doc/autoconf.texi: Add various further index entries.
6074 2003-12-29 Paul Eggert <eggert@twinsun.com>
6076 * bin/autoreconf.in (autoreconf_current_directory):
6077 Fix typo: mkdir without umask arg.
6079 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6081 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6082 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6083 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6084 explanation clearer.
6086 2003-12-24 Andreas Schwab <schwab@suse.de>
6088 * doc/autoconf.texi (Default Includes): Fix misspelling of

6093 * configure.ac: Test if sh -n works.
6094 * configure: Regenerate.
6095 * tests/atlocal.in: Store the result here.
6096 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6097 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6098 of explicitly testing.
6099 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6100 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6101 * tests/tools.at (Syntax of the shell scripts): Simplify
6102 using AT_CHECK_SHELL_SYNTAX.

6116 Extracted from AS_SHELL_SANITIZE.
6117 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6118 macros.
6119 (AS_SHELL_SANITIZE): Move reinvocation code from
6120 _AS_LINENO_WORKS, use it to find out if shell
6121 functions work.
6122 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6123 does not work.
6124 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6125 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

6143 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6171 parameter of AU_DEFUN.

6186 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6187 than $target since the latter is not usual, add guidelines on when to

6269 2003-10-28 Akim Demaille <akim@epita.fr>
6271 * Makefile.cfg (local_updates, executable-update): Tweak to be

6333 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug in
6334 pdksh 5.2.14. Bug reported by Ralf Corsepius.
6335 * doc/autoconf.texi (Shellology): Mention the Korn shell and pdksh.
6336 Mention /usr/dt/bin/dtksh on Solaris.
6337 (Shell Substitutions): Warn about $((...)).
6338 (Parentheses): New section.
6340 2003-10-15 Kevin Ryde <user42@zip.com.au>
6342 * doc/autoconf.texi (Function Portability): Add @prindex for exit.
6343 Add putenv and unsetenv. Add sysconf _SC_PAGE_SIZE.
6345 2003-10-13 Nathanael Nerode <neroden@gcc.gnu.org>
6347 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Trivial fix for vfork
6348 cross test.
6350 2003-10-11 Steven G. Johnson <stevenj@alum.mit.edu>
6352 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Use the new official
6353 name for the GNU Fortran 95+ compiler, 'gfortran', not 'g95'.
6355 2003-10-10 Andreas Schwab <schwab@suse.de>
6357 * bin/autoheader.in: Avoid empty first line in --version and
6358 --help output.
6359 * bin/ifnames.in: Likewise.
6361 2003-10-09 Paul Eggert <eggert@twinsun.com>
6363 * lib/Autom4te/XFile.pm: Don't assume -j is solo.
6364 Issue a more-informative diagnostic.
6365 Problems reported by Eric Sunshine.
6367 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6369 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6370 -mGLOB_options_string stuff for Intel ifc, which can cause
6371 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
6372 pattern-matching instead of grep.
6374 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6376 * doc/autoconf.texi: Document new FC Fortran macros.
6378 2003-10-08 Gary V. Vaughan <gary@gnu.org>
6380 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
6381 that future autopoint/aclocal/automake/autoreconf will be able
6382 to trace to find where to install local m4 macros.
6383 * doc/autoconf.texi (Input): Document it.
6384 * NEWS: Updated.
6386 2003-10-06 Gary V. Vaughan <gary@gnu.org>
6388 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
6389 -lcrtbegin.o to list of ignored flags and fix underquoting of
6390 -lcrt[01].o.
6392 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6394 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6395 cache variable instead of $G77 to decide whether to include -O2,
6396 since $G77 is specific to Fortran 77.
6398 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6400 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6401 free" flag. Re-order flags tested into rough order of popularity.
6403 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6405 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6406 arguments so that it can be used with syntax identical to
6407 AC_PROG_F77, and so that we can more easily decide to
6408 remove/deprecate the DIALECT optional argument in the future if it
6409 proves troublesome.
6410 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6411 non-freeform-supporting compilers. Document freeform flags.
6413 2003-10-03 Akim Demaille <akim@epita.fr>
6415 * configure.ac: Look for emacs, not macs.
6416 Reported by Eric Sunshine.
6418 2003-10-03 Akim Demaille <akim@epita.fr>
6420 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
6421 * bin/autoreconf.in (autoreconf_current_directory): Create the
6422 AUX_DIR if needed, for sake of automake --add-missing etc.
6423 Suggested by Alexandre Duret-Lutz.
6425 2003-10-03 Akim Demaille <akim@epita.fr>
6427 * configure.ac: Quotation and formatting changes.
6428 (EMACS): Don't set it if it is not recent enough to support
6429 autoconf-mode.el.
6430 From Eric Sunshine.
6432 2003-10-02 Akim Demaille <akim@epita.fr>
6434 * bin/ifnames.in (&scan_file): Skip C++ comments.

6446 2003-09-30 Paul Eggert <eggert@twinsun.com>
6448 * lib/Autom4te/XFile.pm: Use Errno.
6449 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
6450 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
6452 2003-09-30 Akim Demaille <akim@epita.fr>
6454 * config/announce-gen (&print_news_deltas): Extracted from...
6455 (&print_changelog_deltas): here.
6456 (&news_file): Rename as...
6457 (@news_file): this.
6459 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
6461 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
6462 have been created when invoking the compiler.
6463 * tests/fortran.at (GNU Fortran 77): Quote $G77.

6471 2003-09-28 Paul Eggert <eggert@twinsun.com>
6473 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
6474 Problem reported by Lars J. Aas in
6475 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6476 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6477 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6478 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6480 2003-09-26 Akim Demaille <akim@epita.fr>
6482 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6483 directory for AC_CONFIG_COMMANDS' first argument exists.
6484 This makes valid the invocation of _AC_SRCPATH that follows.
6485 Reported by Eric Sunshine.
6486 * doc/autoconf.texi (Configuration Commands): Adjust.
6488 2003-09-26 Akim Demaille <akim@epita.fr>
6490 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6491 Reported by Ralf Corsepius.
6493 2003-09-26 Akim Demaille <akim@epita.fr>
6495 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6496 arguments.
6497 Actually, use AU_ALIAS.
6498 From Bruno Haible.
6500 2003-09-26 Paul Eggert <eggert@twinsun.com>
6502 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6503 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6504 Problem reported by Eric Sunshine in:
6505 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
6507 2003-09-26 Akim Demaille <akim@epita.fr>
6509 The test suite are sometimes assigning timings incorrectly.
6510 Reported by Henk Krus.
6511 Diagnosed by Nicolas Joly.
6513 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6514 AT_help_all.
6515 Instead of making AT_help a sequence of assignments to grow
6516 $at_help_all, just make AT_help_all be the growing contents of
6517 $at_help_all, and make a single assignment in...
6518 (AT_INIT): here.
6519 (at_times_skip): Flip the meaning and rename as...
6520 (at_times_p): this.
6521 (AT_INIT): When summarizing the test that ran, remove
6522 $at_times_file after use, and check it is present before trying to
6523 use it.
6525 2003-09-25 Akim Demaille <akim@epita.fr>
6527 Version 2.57d.
6529 * bin/Makefile.am (edit): Handle '@configure_input@'.
6530 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6531 (ifnames): chmod -w.
6532 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6533 executables, not bin/ executables! Otherwise all the magic needed
6534 to find non installed files is turned off. This caused a failure
6535 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6536 as found in its environment (sent by tests/autoreconf): pointing
6537 to bin/autom4te that could not find its files.
6538 * tests/mktests.sh: Force the replacement of generated files, for
6539 the sake of "mv" program that are interactive when overwriting a
6540 -w file.
6541 * config/install-sh: Upgrade from CVS Automake.
6543 2003-09-23 Paul Eggert <eggert@twinsun.com>
6545 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6546 versus test -L issues.
6548 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6549 Paul Eggert <eggert@twinsun.com>
6551 Trivial change to support GCC's configuration procedure.
6552 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6553 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6554 about inconsistency if the preprocessor is set to give errors for
6555 any warning.
6556 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6558 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6560 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6561 and XFile.pm from Automake.

6571 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
6572 from masters.
6574 2003-09-12 Akim Demaille <akim@epita.fr>
6576 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6577 not asm/types.h.
6579 2003-09-11 Akim Demaille <akim@epita.fr>
6581 * doc/autoconf.texi (Header Portability): linux/random.h.
6582 From Peter Hendrickson.
6584 2003-09-10 Akim Demaille <akim@epita.fr>
6586 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6587 willing to edit the output files.
6589 2003-09-10 Akim Demaille <akim@epita.fr>
6591 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6592 and AC_FC_FREEFORM.
6593 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6594 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6596 2003-09-09 Akim Demaille <akim@epita.fr>
6598 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
6599 Reported by Gary Vaughan.
6600 * bin/autom4te.in (handle_m4): Likewise.
6602 2003-09-09 Akim Demaille <akim@epita.fr>
6604 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
6605 trailing files.
6607 2003-09-07 Paul Eggert <eggert@twinsun.com>
6609 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6610 Improve the accuracy of the wording about obsolescence.
6611 From a suggestion by Ian Lance Taylor in
6612 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6614 2003-09-05 Paul Eggert <eggert@twinsun.com>
6616 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6617 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6619 2003-09-04 Akim Demaille <akim@epita.fr>
6621 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6622 AC_FUNC_WAIT3.
6624 2003-09-04 Akim Demaille <akim@epita.fr>
6626 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6627 (freeze): When exiting, use $exit_code.
6628 * lib/autoconf/fortran.m4: Comment changes.
6630 2003-09-04 Akim Demaille <akim@epita.fr>
6632 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6634 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6636 Add support for newer Fortran dialects. The F77 interface is
6637 unchanged, and continues to support Fortran 77. New FC macros
6638 correspond to all the old F77 macros, with output variables FC,
6639 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6640 available dialect, but older dialects can be specified. There are
6641 new macros AC_FC_SRCEXT to set the source extension, and
6642 AC_FC_FREEFORM to accept free-form source files.
6644 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6645 New macros.
6646 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6647 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
6648 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
6649 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

6656 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
6657 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
6658 AC_FC_SRCEXT, AC_FC_FREEFORM):
6659 New macros.
6660 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
6661 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6662 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6663 Rewrite in terms of the above.
6664 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6665 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
6666 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
6667 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
6669 2003-09-02 Paul Eggert <eggert@twinsun.com>
6671 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6672 Document problems with timestamp resolution that 'make', 'cp -p', and
6673 'touch -r' have.
6675 2003-08-27 Akim Demaille <akim@epita.fr>
6677 * tests/m4sugar.at (cross_warning): Make sure to enable the
6678 output, so that we can track spurious m4sugar output.
6679 * tests/local.at: Require 2.57.
6680 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6681 are defaulted by AT_CHECK anyway.
6682 Use AT_CHECK_AUTOM4TE.
6683 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6684 missing dnl.
6686 2003-08-27 Akim Demaille <akim@epita.fr>
6688 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6689 when -Wobsolete is set.
6690 Set it on by default.
6691 Suggested by Klee Dienes.
6693 2003-08-27 Akim Demaille <akim@epita.fr>
6695 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
6696 documentation.
6697 From Guido Draheim.
6699 2003-08-26 Akim Demaille <akim@epita.fr>
6701 * doc/autoconf.texi (Output): Make clear that one can run code
6702 after AC_OUTPUT.
6704 2003-08-25 Akim Demaille <akim@epita.fr>
6706 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
6707 CVS Bison.
6709 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
6711 * bin/autoreconf.in (parse_args): Do not pass --no-force to

6717 From Ville Karaila.
6719 2003-08-24 Akim Demaille <akim@epita.fr>
6721 * configure.ac: Bump to 2.57c.
6723 2003-08-22 Akim Demaille <akim@epita.fr>
6725 Version 2.57b.
6727 * Makefile.cfg (local-checks-to-skip): New.
6728 * Makefile.maint (local-check): Rename as...
6729 (local-checks-available): this.
6730 (local-check): New.
6732 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6733 * configure.ac: Require Automake 1.7.6.
6735 2003-08-22 Akim Demaille <akim@epita.fr>
6737 Output stack traces in warnings.
6739 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6740 Replace the former...
6741 (m4_warn): Pass the call stack to _m4_warn.
6742 * bin/autom4te.in: Adjust to output the call stack.
6743 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6745 2003-08-22 Akim Demaille <akim@epita.fr>
6747 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6748 * bin/autom4te.in: Adjust.
6750 2003-08-21 Akim Demaille <akim@epita.fr>
6752 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6753 (&verbose): Remove.
6754 (&getopt): Adjust the note and verb channels, depending upon
6755 --verbose.
6756 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6757 * bin/autoupdate.in: Adjust.
6758 Use &verb, not &verbose.
6760 2003-08-21 Akim Demaille <akim@epita.fr>
6762 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6763 &parse_WARNINGS.
6764 ($help): Use Autom4te::ChannelDefs::usage.
6765 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6766 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6768 2003-08-21 Akim Demaille <akim@epita.fr>
6770 First stab at preserving warnings between calls to autom4te,
6771 including when the cache is used.
6773 There are still several issues: (i) there are too many runs of m4
6774 (one for include, one for warnings, and some more), (ii) warnings
6775 spreading on several lines are not handled gracefully, (iii) the
6776 code meant to have the call stack display for errors does not work
6777 (its handling should move from m4 to autom4te).
6779 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6780 Use them.
6781 (@preselect): Add m4_warn.
6782 ($exit_status): Remove, use $exit_code.
6783 ($help): Use Autom4te::ChannelDefs::usage.
6784 (&handle_m4): No longer define the m4_warnings.
6785 At each run, extract and report the warnings.
6786 Always cache the result, including if the exit status is on
6787 failure, since if nothing changes, we should result in the same
6788 failure, hence we can use the cache.
6789 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6790 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6791 Remove.
6792 (m4_warn): Redefine as a do-nothing: it is its invocation that
6793 matters, as warnings are now reported via traces.
6794 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6795 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6796 the latter reveals calls to the former.
6798 Adjust the tests.

6837 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6838 (&xsystem, &contents): Remove, since they are exported by...
6839 * lib/Autom4te/FileUtils.pm: this.
6840 More perldoc.
6841 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6842 * lib/Autom4te/FileUtils.pm: here.
6844 2003-08-20 Akim Demaille <akim@epita.fr>

6903 2003-08-13 Derek Price <derek@ximbiot.com>
6905 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6906 output.
6908 2003-08-12 Derek Price <derek@ximbiot.com>
6910 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
6911 (AT_CHECK_NOESCAPE): Move core functionality to...
6912 (_AT_CHECK): ...this new macro.
6914 2003-08-07 Derek Price <derek@ximbiot.com>
6916 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
6917 (AT_CHECK_NOESCAPE): ...to this new macro.
6919 2003-07-31 Paul Eggert <eggert@twinsun.com>
6921 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6922 in Bash 2.01. Problem reported by Brian Gough in
6923 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6925 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
6927 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
6928 -lcrt1.o, for OS X. (trivial change)
6930 2003-07-07 Paul Eggert <eggert@twinsun.com>
6932 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
6933 inside '#ifndef __cplusplus'. Problem reported by
6934 Bob Friesenhahn.
6936 2003-07-06 Bill Clarke <llib@computer.org>
6938 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6939 'long', not 'int', for benefit of Sun's recent C++ compilers
6940 (trivial change). See:
6941 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6942 (This really should be 'intptr_t', not 'long', but that would
6943 take more work.)
6945 2003-06-25 Akim Demaille <akim@epita.fr>
6947 * lib/Makefile.am (autom4te.cfg): Make it read only.
6948 Depend on Makefile since it contains substitutions.
6949 From Paolo Bonzini.

6954 2003-06-25 Akim Demaille <akim@epita.fr>

6957 From Gareth McCaughan.
6959 2003-06-23 Akim Demaille <akim@epita.fr>
6961 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6962 not all of them. This fixes 1. the fact that when testing
6963 Autoconf there are many many config.log, 2. the incorrect use of
6964 top_srcdir to find config.log.
6965 Don't mix the detailed output of failed test with the summary of
6966 failures. Rather, append detailed log afterwards.
6968 2003-06-23 Akim Demaille <akim@epita.fr>
6970 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6971 always run: output config.log on $at_group_log.
6973 2003-06-23 Akim Demaille <akim@epita.fr>
6975 * tests/torture.at (#define header templates): Don't use quotes in

6980 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6981 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
6982 * tests/atspecific.m4: Rename as...

6989 2003-06-21 Kevin Ryde <user42@zip.com.au>
6991 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6992 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6993 ensuring we add -std1 for full-ANSI.
6995 * doc/autoconf.texi (hdrindex): New macro.

6998 2003-06-20 Akim Demaille <akim@epita.fr>

7002 2003-06-20 Akim Demaille <akim@epita.fr>
7004 Version 2.57a.
7006 2003-06-20 Akim Demaille <akim@epita.fr>
7008 * bin/autom4te.in: Don't rely on $HOME being defined.
7009 Reported by Marc Espie as PR/233.
7011 2003-06-20 Akim Demaille <akim@epita.fr>
7013 * lib/autotest/general.m4: Use at_times_file only if used.
7014 From Nicolas Joly.

7018 * config/config.guess, config/config.sub, config/elisp-comp,
7019 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7020 Update from masters.
7022 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7024 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7025 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7026 (TEST_SCRIPT): New diversion.
7027 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7028 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7029 (AT_INIT): Support for expected failures.
7031 2003-06-02 Akim Demaille <akim@epita.fr>
7033 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7034 changes.
7035 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7036 Autoconf nor Automake.
7037 (&contents): New, from Automake.
7038 PODify.
7040 2003-05-28 Paul Eggert <eggert@twinsun.com>
7042 * NEWS, doc/autoconf.texi (Particular Functions),
7043 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7044 is the inverse of localtime.
7046 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7048 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7049 (handle_exec_errors): New function. Work around $! being
7050 altered by WEXITSTATUS.
7051 (xqx, xsystem): Use handle_exec_errors.
7053 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7055 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7056 Do not call `_exit()', simply modify `$?'.
7057 (xsystem): Reset $! before running system, and check it afterward.
7058 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7059 63 for version mismatches.
7061 2003-05-23 Akim Demaille <akim@epita.fr>
7063 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7064 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7065 the middle of a line).
7066 * lib/m4sugar/m4sugar.m4: Likewise.
7067 Remove useless spaces in comments.
7069 2003-05-23 Akim Demaille <akim@epita.fr>
7071 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7072 exit 63, so that we (or Automake's "missing") can tell the
7073 difference with a plain failure.
7074 * doc/autoconf.texi (Notices): Adjust.
7076 2003-05-23 Akim Demaille <akim@epita.fr>
7078 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7079 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7080 White spaces cleanup.
7082 2003-05-22 Jim Meyering <jim@meyering.net>
7083 Paul Eggert <eggert@twinsun.com>
7085 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7086 Remove `#include <stdlib.h>' from the list; we should never
7087 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7088 resulting namespace pollution would cause other tests to fail.
7089 Configure scripts run with some older versions of g++ and HP's
7090 aCC would fail due to such an #include. Problems reported by
7091 Matthew Mueller in <http://bugs.debian.org/120704> and by
7092 Keith Bostic in
7093 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7094 In the test, use the test declaration before including <stdlib.h>,
7095 as that's closer to how it'll be used.
7097 2003-05-23 Akim Demaille <akim@epita.fr>
7099 * doc/autoconf.texi (Header Portability): ucred.h.
7100 From Ian Redfern.
7102 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7104 Overhaul Autotest's logging: generate separate log files
7105 in testsuite.dir/NNN/testsuite.log, and append them to
7106 testsuite.log instead of re-running the test verbosely.
7108 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7109 file descriptor, write 0 to at_status_file instead of setting
7110 at_status=0, initialize some new variables (at_status_file,
7111 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7112 to rerun the tests, instead append the at_group_log to the
7113 at_suite_log when a test fails.
7114 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7115 with the AS_MESSAGE_LOG_FD redirected to stdout.
7116 (AT_CLEANUP): save the output status in $at_status_file
7117 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7118 its original place.
7119 (AT_CHECK): since tests are run with a redirected stdout,
7120 and used to be re-run in verbose mode, turn some $at_verbose
7121 into echo, and don't redirect the output of testing stdout
7122 and stderr.
7124 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7125 the name of the debugging directory and information about
7126 its contents.
7128 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7130 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7131 parameter.
7133 2003-05-22 Akim Demaille <akim@epita.fr>
7135 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
7136 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
7137 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

7154 Suggested by Jim Meyering.
7156 2003-05-22 Akim Demaille <akim@epita.fr>
7158 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
7159 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
7160 Reported by Jim Meyering.
7162 2003-05-22 Akim Demaille <akim@epita.fr>
7164 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

7197 2003-05-17 Akim Demaille <akim@epita.fr>
7199 * lib/autoconf/functions.m4: Use the default includes so that
7200 memcmp be declared before being tested.
7201 Reported by Sander Niemeijer.
7202 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7203 * doc/autoconf.texi (Default Includes): Document
7204 AC_INCLUDES_DEFAULT.
7206 2003-05-17 Akim Demaille <akim@epita.fr>
7208 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
7209 * doc/autoconf.texi (Obsolete Macros): Adjust.
7210 Reported by Werner LEMBERG and Debian Bug 190886.
7212 2003-05-16 Akim Demaille <akim@epita.fr>
7214 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
7215 user name space clashes.
7216 Reported by Bruno Haible.
7218 2003-05-16 Akim Demaille <akim@epita.fr>
7220 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7221 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
7222 them uniform, and more robust to Perl special characters.
7223 Reported by Martin Mokrejs.
7225 2003-05-14 Akim Demaille <akim@epita.fr>
7227 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
7229 2003-05-14 Akim Demaille <akim@epita.fr>
7231 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

7236 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
7237 message.
7238 From Matthias Andree.
7240 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
7242 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
7243 and truncate.
7245 2003-05-06 Akim Demaille <akim@epita.fr>
7247 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7248 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7249 by aclocal.m4 is changed it might require the importing of another
7250 m4 extension file, i.e., aclocal must be run.
7252 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7253 (&parse_args): Use --force with aclocal if required and supported.
7254 (&autoreconf_current_directory): Use &run_aclocal.
7256 2003-05-06 Akim Demaille <akim@epita.fr>
7258 Lock autom4te's cache.
7260 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7261 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7262 argument instead of a file name, so that the request file remains
7263 open during the whole autom4te run.
7264 ($icache_file): New.
7265 (&freeze): Lock the $icache_file.
7267 2003-04-29 Derek Price <derek@ximbiot.com>
7269 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7270 seperator with m4_append_uniq(). It doesn't work.
7271 (AT_CLEANUP): Add `;' to end of at_help_all.
7272 (AT_INIT): Allow --keywords to be specified more than once. When
7273 grepping $at_help_all for keywords, use the field and keyword
7274 seperators to ensure a complete keyword match. Alter at_prev handling
7275 to support the new --keywords behavior.
7277 2003-04-27 Karl Berry <karl@freefriends.org>
7279 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7280 align better with others. I also made some of the individual
7281 entries on one line, for brevity and to make it easier for me to
7282 sort my dir-example file in the Texinfo distribution :).
7284 2003-04-12 Jim Meyering <jim@meyering.net>

7446 to cope with DOS-style absolute paths, when constructing
7447 ${ac_make}.
7449 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7450 When constructing paths with IFS=:, quote the path. If we're
7451 constructing a DOS-style absolute path, we don't want to split it
7452 on the colon.
7454 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7455 in description.
7457 2003-02-25 Pavel Roskin <proski@gnu.org>

7469 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7470 to fix a mismatch between example and discussion.

7474 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7475 format starting with "-".
7477 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7479 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7480 is not portable inside Makefile.
7482 2003-02-20 Akim Demaille <akim@epita.fr>
7484 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7485 compiler says yeah, but preproc says nope, compiler is right.
7486 Conversely, prompt the reader to send a bug report to the
7487 maintainers of the package, not of Autoconf.
7489 2003-02-20 Klee Dienes <kdienes@apple.com>

7498 From Larry Jones.
7500 2002-12-23 Paul Eggert <eggert@twinsun.com>
7502 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7503 innocuous variant befor including <limits.h> or <assert.h>. This
7504 works around a bug reported by Albert Chin: HP-UX 11i
7505 (and earlier versions) have a <limits.h> that declares
7506 gettimeofday and many other functions.
7508 2002-12-03 Paul Eggert <eggert@twinsun.com>
7510 Version 2.57.
7512 * NEWS, configure.ac: Update version.
7514 * doc/fdl.texi: Upgrade to FDL version 1.2.
7516 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7517 nontrivially in main's body, so that f's external declaration is
7518 not optimized away in AIX. This should fix the bug reported by
7519 Martin Frydl in
7520 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7522 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7523 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7524 defined, to support freestanding compilers. This should fix the
7525 bug reported by Momchil Velkov in
7526 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7528 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7529 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

7542 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7544 2002-11-15 Akim Demaille <akim@epita.fr>

7553 Require 1.7.1.
7555 2002-11-14 Akim Demaille <akim@epita.fr>
7557 Version 2.55.
7559 * config/config.guess, config/config.sub, config/install-sh:
7560 Update from masters.
7562 2002-11-14 Akim Demaille <akim@epita.fr>
7564 * Makefile.maint: Sync with Bison, i.e.:
7565 (po-check): Scan .l and .y files instead of the
7566 .c and the .h files that they generate. This fixes the bug
7567 reported by Tim Van Holder in:
7568 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7569 Look for N_ as well as for _. Try to avoid matching #define for
7570 N_ and _.
7571 From Paul Eggert.
7573 2002-11-14 Akim Demaille <akim@epita.fr>
7575 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7576 From Paul Eggert and Albert Chin-A-Young.
7578 2002-11-14 Akim Demaille <akim@epita.fr>

7581 From Paul Eggert and Albert Chin-A-Young.
7583 2002-11-14 Kevin Ryde <user42@zip.com.au>
7585 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7586 than assigning in main, to avoid HP cc +O3 optimizing it away.
7588 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7590 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7591 option. Process --recheck after parsing all options. Pass -q
7592 option to configure on --recheck.
7593 (AC_OUTPUT): Pass -q from configure to config.status.
7594 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7595 arguments to record.
7596 * doc/autoconf.texi (config.status Invocation): Document
7597 config.status -q option.
7599 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

7602 Makefile.in if Makefile.am exists.

7604 output AC_CONFIG_FILES if no Makefiles were found.
7606 2002-11-07 Akim Demaille <akim@epita.fr>

7613 2002-11-06 Akim Demaille <akim@epita.fr>
7615 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7616 declaration in extern "C" too.

7621 * tests/torture.at (Configuring subdirectories): Don't use grep
7622 -w.
7623 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7624 Reported by Ezra Peisach.
7626 2002-11-05 Akim Demaille <akim@epita.fr>
7628 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7629 Remove.
7630 We _have_ to stop using the old compatibility scheme that tried to
7631 avoid useless backslashes because Libtool 1.4.3 contains a
7632 AC_DEFINE([error_t], [int],
7633 [Define to a type to use for \`error_t' if it is not
7634 otherwise available.])
7635 We _have_ to quote the single quote and backslashes with \. The
7636 old compatibility scheme saw that ` was backslashed, and therefore
7637 did not quote the single quote. Hence before this patch, Autoconf
7638 was not compatible with Libtool.
7640 2002-11-04 Paul Eggert <eggert@twinsun.com>
7642 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

7647 2002-11-04 Akim Demaille <akim@epita.fr>
7649 Version 2.54c.

7652 New.
7653 * config/texinfo.tex: Update.
7655 2002-11-03 Akim Demaille <akim@epita.fr>
7657 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7658 from...
7659 (&autoreconf): here.
7660 ($help, $make, &parse_args, &autoreconf_current_directory):
7661 Support -m/--make.
7662 * doc/autoconf.texi (autoreconf Invocation): Adjust.

7677 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
7678 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
7680 2002-10-31 Akim Demaille <akim@epita.fr>
7682 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7683 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7684 Make variable, not a shell variable.
7685 Suggested by Bruno Haible.
7687 2002-10-31 Akim Demaille <akim@epita.fr>
7689 * bin/autom4te.in (load_configuration): Reject #args out of any
7690 language.
7692 2002-10-31 Akim Demaille <akim@epita.fr>
7694 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
7695 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
7696 (_AC_RUN_IFELSE): Use it.
7697 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
7698 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
7699 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
7700 inline it.

7706 Suggested by Tim van Holder.
7708 2002-10-29 Paul Eggert <eggert@twinsun.com>
7710 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
7711 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7712 Problem reported by Bruno Haible.
7714 2002-10-29 Akim Demaille <akim@epita.fr>
7716 * doc/autoconf.texi (Header Templates): Put also in words what the
7717 pictures says to assist free style readers.
7718 (Customizing autom4te): s/--cache=/--cache /.
7720 2002-10-29 Akim Demaille <akim@epita.fr>
7722 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
7723 sys/wait.h.
7724 sparc_address_test returns void.
7725 Use it with an argument, as prototyped.
7726 From Bruno Haible.
7728 2002-10-29 Akim Demaille <akim@epita.fr>
7730 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

7736 * tests/torture.at (Deep Package): New test.

7742 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
7743 * doc/autoconf.texi (Invoking autom4te): Rename as...
7744 (autom4te Invocation): this, for consistency with the other nodes.
7746 2002-10-29 Akim Demaille <akim@epita.fr>
7748 * lib/autom4te.in (Autoconf): s/automate/autom4te/.
7749 Reported by Ralf Corsepius.

7759 * configure.ac: Bump to 2.54c.

7970 2002-10-22 Akim Demaille <akim@epita.fr>

8028 longer required can still cause errors.
8029 Reported by Alexandre Duret-Lutz.
8031 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8032 to frozen files in @ARGV, as @ARGV must remain being a list of

8034 (&files_to_options): New function.
8035 (&freeze): Use &error.
8036 (&up_to_date): If a file that was included according to the cache
8037 is no longer there, then the output is out dated.

8039 --force is given.
8040 * tests/tools.at (autom4te cache): New.

8049 that error messages can be easily located, and use GNU Make
8050 format, so that Emacs' compile mode understands us.
8051 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8052 if some file was changed instead of `print'.
8053 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8087 file name to enable parallel executions.
8088 From Sam Varshavchik.
8090 2002-10-08 Akim Demaille <akim@epita.fr>
8092 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8093 aclocal invocation, as Gettext macros might not be visible to
8094 aclocal.
8095 Instead of blindly running autopoint, scan configure.ac (not the
8096 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8097 Reported by Paul D. Smith.
8099 2002-10-08 Paul Eggert <eggert@twinsun.com>
8101 Work around problems found when POSIXLY_CORRECT=1 is set.
8102 None of this seems to have anything to do with POSIX, really,

8104 * bin/autom4te.in (parse_args): Configure GetOpt with
8105 "permute", too.
8106 * doc/autoconf.texi (Invoking autom4te):

8129 * tests/torture.at (Configuring subdirectories): Be robust to
8130 users who use config.site to require for a cache: in this case,
8131 the two last configure runs, using two different sets of
8132 arguments, trigger a legitimate error.
8134 2002-09-28 Akim Demaille <akim@epita.fr>

8169 tests/autom4te itself.
8170 * lib/autoscan/Makefile.am: Include freeze.mk.
8171 (autoscan.list): New target --this file is no longer a source.

8198 2002-09-28 Akim Demaille <akim@epita.fr>
8200 From now on, autoscan files must always map a macro name to a
8201 word: there is no `default' macro for autoscan.
8203 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8204 all.
8205 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8206 explicit.
8208 2002-09-28 Akim Demaille <akim@epita.fr>

8244 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8246 2002-09-26 Akim Demaille <akim@epita.fr>
8248 Single suffix rules and seperated dependencies are not portable.

8276 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8278 2002-09-13 Paul Eggert <eggert@twinsun.com>
8280 * doc/autoconf.texi (Particular Headers): Remove obsolete
8281 reference to `struct timezone' in the description of
8282 AC_HEADER_TIME.
8284 2002-09-13 Akim Demaille <akim@epita.fr>
8286 Version 2.54.
8288 * config/config.sub, config/config.guess: Update.
8289 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8290 * Makefile.am: Adjust.
8292 2002-09-13 Akim Demaille <akim@epita.fr>
8294 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8295 reading config.log when the compiler is rejected.
8296 Suggested by Guido Draheim.
8298 2002-09-13 Akim Demaille <akim@epita.fr>
8300 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8301 (chdir_init) might hang when stat'ing mounted directories.
8302 Reported by Vance Shipley.
8304 2002-09-12 Akim Demaille <akim@epita.fr>
8306 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8307 the lists.
8309 2002-09-12 Akim Demaille <akim@epita.fr>
8311 * doc/autoconf.texi (Defining Symbols): Present two different
8312 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8313 difference between 1 argument calls, and 2-3 argument calls.
8315 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8317 * doc/autoconf.texi: Review grammar and punctuation.
8319 2002-09-11 Paul Eggert <eggert@twinsun.com>
8321 * doc/autoconf.texi: Fix minor formatting, spelling, and
8322 grammatical typos.
8323 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8324 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8325 is obsolescent.
8327 2002-09-11 Akim Demaille <akim@epita.fr>
8329 * doc/autoconf.texi (Questions): Rename as...
8330 (FAQ): this.
8331 (Defining Directories): New.
8333 2002-09-09 Akim Demaille <akim@epita.fr>
8335 * doc/autoconf.texi (Making testsuite Scripts): Update.
8336 Suggested by Nishio Futoshi.
8338 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8340 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8341 plain `@' is wanted.
8343 2002-09-09 Akim Demaille <akim@epita.fr>
8345 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8346 `duplicates', since the algorithm was too naive and could keep
8347 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8348 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8349 Reported by Ralf Corsepius.
8350 * tests/torture.at (Configuring subdirectories): Exercise these
8351 cases.
8353 2002-09-09 Akim Demaille <akim@epita.fr>
8355 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8356 looking for a replacement file.
8357 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8358 directory is relative.
8359 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8360 directory definition.
8361 Reported by Andreas Schwab and Jim Meyering.
8363 2002-09-06 Akim Demaille <akim@epita.fr>
8365 * doc/autoconf.texi (Setting Output Variables): Clarify what
8366 precious variables are.
8367 Suggested by Pontus Skoeld.
8369 2002-09-05 Akim Demaille <akim@epita.fr>
8371 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8372 (ifnames, autoscan, autom4te): Since we don't only depend on
8373 configure.ac variables (such as VERSION etc.), but also on prefix
8374 and so forth, depend on Makefile, not configure.ac.
8375 Reported by Alexandre Duret-Lutz.
8376 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8378 2002-09-05 Kevin Ryde <user42@zip.com.au>
8380 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8381 doesn't seem to be confined to ia64, just say "some versions".
8383 2002-09-04 Akim Demaille <akim@epita.fr>
8385 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8386 Automake 1.6c.
8387 * Makefile.am (maintainer-clean-local): Remove.
8388 (MAINTAINERCLEANFILES): Remove COPYING.
8390 2002-09-03 Paul Eggert <eggert@twinsun.com>
8392 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8393 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8394 Brinkmann.
8396 2002-09-03 Akim Demaille <akim@epita.fr>
8398 * configure.ac: Bump to 2.53d.
8399 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8400 as of today, on Automake's team suggestion.
8402 2002-09-03 Akim Demaille <akim@epita.fr>
8404 Version 2.53c.
8406 2002-09-02 Akim Demaille <akim@epita.fr>
8408 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8409 SITE_MACRO_DIR.
8410 * configure.ac: Disable SITE_MACRO_DIR.
8412 2002-09-02 Jim Meyering <meyering@lucent.com>
8414 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8415 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8416 Also, tweak grammar: s/make sure to/be sure to/.
8418 2002-09-02 Paul Eggert <eggert@twinsun.com>
8420 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8421 directory names are generally preferable to physical names.
8423 2002-09-02 Akim Demaille <akim@epita.fr>
8425 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8426 Reported by Raja R. Harinath.
8427 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8428 * bin/autoupdate.in: Use error instead of die.
8430 2002-09-01 Paul Eggert <eggert@twinsun.com>
8432 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8433 ordinary shell concatenation rather than echo+tr+sed command that
8434 runs afoul of a long-line-related sed bug in Solaris 8.
8436 * bin/autoheader.in (parse_args): --warning -> --warnings.
8438 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8439 stdout, as traditional "ls" does.
8440 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8441 _AC_COMPILER_EXEEXT_O): Likewise.
8442 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8444 * bin/autoconf.as: Add --prepend-include option. This patch was
8445 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8446 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8448 * bin/autoconf.in, configure: Regenerate.
8450 * doc/autoconf.texi (Special Shell Variables): Mention
8451 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8453 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8454 MAILPATH and set PS1, PS2, PS4 to default values, to work
8455 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8456 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8457 the Autoconf documentation specifies; fall back to "unset" only if
8458 this fails. Use a shell for-loop for this rather than an m4 loop,
8459 to shorten the output script.
8461 2002-08-30 Paul Eggert <eggert@twinsun.com>
8463 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8464 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8465 for the CDPATH problem. Document PWD.
8466 (Limitations of Builtins): Document the problem that "cd $foo" and
8467 "ls $foo" may refer to different directories in shells conforming
8468 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8469 example, since the old example is now out of date.
8471 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8472 FOO" and "ls FOO" talk about different directories; this catches
8473 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8474 spaghetti.
8476 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8477 of rolling our own unset.
8478 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8479 in practice we needn't worry about CDPATH if unset doesn't work.
8481 * Makefile.in, aclocal.m4, bin/Makefile.in,
8482 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8483 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8484 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8485 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8486 tests/Makefile.in: Regenerate with Automake 1.6.3.
8488 * config/config.guess, config/config.sub, config/mkinstalldirs:
8489 Update.
8491 * configure: Regenerate with self.
8493 2002-08-30 Kevin Ryde <user42@zip.com.au>
8495 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8496 default output.
8498 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8500 * bin/autom4te.in (Request::load): Correctly test for "do" read
8501 failure.
8503 2002-08-29 Akim Demaille <akim@epita.fr>
8505 * lib/Autom4te/General.pm (&xqx): New.
8506 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8507 hand, which is not portable.
8508 (&error): New.
8509 * bin/autom4te.in: Use them.
8510 Use &error instead of die.
8511 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8512 Adjust.
8514 2002-08-17 Paul Eggert <eggert@twinsun.com>
8516 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8517 default list of compilers to try, since it was long ago superseded
8518 by the ksh fc builtin. Suggested by Steven G. Johnson.
8520 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8522 * doc/autoconf.texi (Invoking autom4te): End the option table,
8523 fixing a bug introduced by the previous patch.
8524 (Limitations of Make): Add a 'target lookup' subentry in the
8525 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8527 2002-07-29 Mark D. Roth <roth@feep.net>
8529 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8530 options and use $AUTOM4TE_PATH.
8531 * doc/autoconf.texi: Remove documentation of autom4te
8532 --include-envvar and --site-macro-subdir options and document
8533 use of $AUTOM4TE_PATH.
8534 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8535 arguments from each language section.
8537 2002-07-29 Paul Eggert <eggert@twinsun.com>
8539 * doc/install.texi: Include copyright symbol in copyright notice.
8541 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8542 Replace with:
8543 (AM_MAKEINFOFLAGS): New macro.
8544 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8545 * Makefile.am (INSTALL): Use the new macros.
8546 Use -o rather than --output, since "missing" does not grok --output.
8548 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8550 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8551 comments do not always work. Never trust the exit status of
8552 `make -k'.
8554 2002-07-24 Kevin Ryde <user42@zip.com.au>
8556 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8557 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8559 2002-07-23 Paul Eggert <eggert@twinsun.com>
8561 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8562 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8563 apparently treats PATH="nonexistent" as if it contained ".".
8564 Bug reported by Stefan `Sec' Zehl.
8566 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8568 * doc/autoconf.texi (Limitations of Make): Mention the special
8569 handling of the obj/ directory by BSD make.

8585 2002-07-18 Akim Demaille <akim@epita.fr>
8587 Version 2.53b.
8589 2002-07-18 Akim Demaille <akim@epita.fr>
8591 * config/config.guess, config/config.sub: Update.
8593 2002-07-18 Akim Demaille <akim@epita.fr>
8595 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8596 Automake's parts.

8599 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
8600 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
8602 2002-07-18 Akim Demaille <akim@epita.fr>,
8603 Alexandre Duret-Lutz <duret_g@epita.fr>
8605 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

8611 description of the tarname default.

8615 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
8616 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
8617 latter was not run.
8619 2002-07-17 Akim Demaille <akim@epita.fr>
8621 * lib/Autom4te/General.pm (find_file): Browse the directories in
8622 the order they are given.

8642 macro directory, remove note that include path directories are
8643 used in reverse order, and document --prepend-include option.
8644 * lib/autom4te.in: Use --prepend-include instead of --include.
8645 * tests/wrapsh.in: Use --prepend-include instead of --include.
8647 2002-07-17 Akim Demaille <akim@epita.fr>

8695 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
8697 * tests/mktests.sh: Use grep instead of fgrep, as per
8698 "Limitations of Builtins".
8700 2002-06-15 Paul Eggert <eggert@twinsun.com>
8702 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
8703 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
8704 so that we consistently test the just-built programs.
8705 * tests/wrappl.as: Likewise.
8707 2002-06-12 Paul Eggert <eggert@twinsun.com>
8709 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
8710 name, so that symlinks to 'autoconf' work properly. Bug reported
8711 by Bruno Haible.
8712 * bin/autoheader.in (AUTOM4TE): Likewise.
8713 * bin/autoreconf.in (autoconf, autoheader): Likewise.
8714 * bin/autoscan.in (autom4te): Likewise.
8715 * bin/autoupdate.in (autom4te): Likewise.
8717 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
8718 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
8719 on Solaris 2.5.1.
8721 2002-06-11 Andreas Schwab <schwab@suse.de>
8723 * doc/autoconf.texi: Add more dir entries.
8725 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8727 * bin/autom4te.in ($cache): Don't define using `$me', the name
8728 of the cache should not depend on the name under which autom4te
8729 was installed.
8731 2002-06-07 Akim Demaille <akim@epita.fr>
8733 * tests/tools.at (autoconf: forbidden tokens, basic)
8734 (autoconf: forbidden tokens, exceptions): Adjust to the change of
8735 words in autom4te.in.
8737 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
8739 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use

8770 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
8771 (AC_REPLACE_FNMATCH_GNU): these.
8772 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
8773 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
8774 * tests/mktests.sh (ac_exclude_list): Don't check
8775 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
8777 2002-06-06 Paul Eggert <eggert@twinsun.com>
8779 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
8780 if ln doesn't work.
8781 * NEWS: Likewise.
8782 * doc/autoconf.texi (Configuration Links): Likewise.
8783 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
8785 2002-06-05 Paul Eggert <eggert@twinsun.com>
8787 * config/config.guess, config/config.sub, config/texinfo.tex:
8788 Update from masters.
8790 2002-05-29 Paul Eggert <eggert@twinsun.com>
8792 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
8793 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
8794 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):
8795 Likewise.
8796 * lib/autoconf/Makefile.am (check-local): Likewise.
8797 * lib/autoconf/status.m4 (AC_CONFIG_HEADER): Likewise.
8798 * lib/autoconf/types.m4 (commentary only): Likewise.

8805 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
8806 * doc/autoconf.texi (Particular Programs): Document them.
8807 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
8808 * NEWS: Likewise.
8810 2002-05-27 Paul Eggert <eggert@twinsun.com>
8812 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
8813 * NEWS, doc/autoconf.texi (Particular Types): Document it.
8814 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
8815 instead of AC_MBSTATE_T, which never existed.
8817 2002-05-23 Akim Demaille <akim@epita.fr>
8819 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
8820 version of Autoconf that is discussed.
8822 2002-05-22 Paul Eggert <eggert@twinsun.com>
8824 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8825 from the default list of compilers to try. Suggested by
8826 Kate Hedstrom.
8827 * NEWS: Document the above.
8828 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8830 2002-05-17 Paul Eggert <eggert@twinsun.com>
8832 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8833 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8834 This improves on an earlier suggestion by H. Peter Anvin.
8836 2002-05-16 Paul Eggert <eggert@twinsun.com>
8838 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8839 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8840 Both macros now accept an optional source-dir arg.
8841 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8843 * NEWS: Document this.
8844 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8846 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8847 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8848 not for GNU extensions; this undoes part of the 2000-11-03 change,
8849 reverting to 2.13-compatible behavior.
8850 Add new optional argument DIR.
8851 (AC_FUNC_FNMATCH_GNU): New macro.
8853 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8855 2002-05-08 Paul Eggert <eggert@twinsun.com>
8857 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8858 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8859 and it causes a 'test' syntax error if it fails.
8860 Bug reported by Stephen Gildea.
8862 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8863 If prototypes are supported, use them to check this at compile-time,
8864 instead of trying to check it at run-time. If we must do a run-time
8865 check, assume that setvbuf is standard when cross-compiling, as
8866 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8867 Bug reported by Paul D. Smith.
8869 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8870 argument specifying location of getloadavg.c. This removes a
8871 FIXME. This idea was taken from Jim Meyering's implementation in
8872 textutils.
8873 * doc/autoconf.texi (Particular Functions): Document this.
8874 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8875 that's what the code does; this fixes a bug reported by
8876 Paul D. Smith.
8878 2002-05-03 Akim Demaille <akim@epita.fr>
8880 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8881 autopoint instead of gettextize.
8882 ($uses_alocal): Rename as...
8883 ($uses_aclocal): this.
8884 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8885 Suggested by Bruno Haible.
8887 2002-05-03 Akim Demaille <akim@epita.fr>
8889 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8891 2002-04-29 Paul Eggert <eggert@twinsun.com>
8893 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8894 files to be 1 second older; just set them to be the same time.
8895 Also, sleep 1 second after the first aclocal, to work around
8896 problems with sub-second time stamps on the input files.
8898 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8900 * doc/autoconf.texi: Mention "set -e -x" lossage
8901 under node "Limitations of Builtins".
8903 2002-04-29 Akim Demaille <akim@epita.fr>
8905 * doc/install.texi: Better wording for setting variables when
8906 running configure.
8907 From Christian Cornelssen.
8909 2002-04-29 Akim Demaille <akim@epita.fr>
8911 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8912 of lack of $LINENO support, then the test will compare the $LINENO
8913 in testsuite vs. the lineno in the test file. This is wrong, of
8914 course.
8915 Be sure to protect it.
8916 Reported by Patrick Welche.
8918 2002-04-25 Akim Demaille <akim@epita.fr>
8920 * doc/autoconf.texi (Obsolete Macros): Typo.
8921 Reported by Vladimir Volovich.
8923 2002-04-25 Akim Demaille <akim@epita.fr>
8925 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8926 than some of the input files, hence, on the second run of aclocal,
8927 if some of its input are younger, make them older.
8928 Suggested by Paul Eggert.
8930 2002-04-25 Akim Demaille <akim@epita.fr>
8932 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8933 Thanks to Paul Eggert.
8935 2002-04-25 Akim Demaille <akim@epita.fr>
8937 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8938 and ac_subst_vars be sh variables containing the list of
8939 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8940 DEFAULT diversion.
8941 (_AC_INIT_PREPARE): Use them to log them.
8942 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8943 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8944 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8945 _AC_SUBST_FILES and _AC_SUBST_VARS.
8946 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8948 2002-04-24 Akim Demaille <akim@epita.fr>
8950 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8951 autoheader, so that automake does not complain about a missing
8952 config.h.in that was to be created.
8954 2002-04-23 Akim Demaille <akim@epita.fr>
8956 * bin/autoheader.in (parse_args): --warning takes an argument.
8957 Fixes PR/220.
8959 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8961 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
8962 and bb.out when cleaning up.
8964 2002-04-22 Akim Demaille <akim@epita.fr>
8966 Version 2.53a.
8968 2002-04-22 Akim Demaille <akim@epita.fr>
8970 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
8972 2002-04-22 Akim Demaille <akim@epita.fr>
8974 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
8975 comma.
8976 Reported by Gregory Giannoni.
8978 2002-04-22 Akim Demaille <akim@epita.fr>
8980 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
8981 Fixes false failures on Darwin.
8983 2002-04-21 Paul Eggert <eggert@twinsun.com>

8987 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

9006 Minor spelling and grammar fixes.
9008 * doc/autoconf.texi: Follow the outline suggested in the GNU
9009 Sample Texts sections of the Texinfo 4.2 manual. Most
9010 importantly, this makes sure that the copyright notices appear in
9011 all output formats. You probably need Texinfo 4.2 to generate
9012 the manual now.
9014 Fix some bugs when using "$@" when there might be zero positional
9015 arguments in cases where this matters.

9036 that is not portable to Zsh.
9038 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9040 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9041 from aclocal.m4 too.
9043 2002-04-12 Akim Demaille <akim@epita.fr>
9045 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9047 2002-04-10 Akim Demaille <akim@epita.fr>
9049 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9050 workaround for ${1+"$@"}.
9051 * doc/autoconf.texi (Shell Substitutions): Explain it.
9052 From Oliver Kiddle and Peter Stephenson.
9054 Have M4sh perform minimal shell sanitizing.
9056 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9057 part into...
9058 (_AS_PREPARE): this new macro.
9059 (AS_PREPARE): New.
9060 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9061 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9063 Adjust Autoconf and Autotest.
9065 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9066 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9067 * lib/autotest/general.m4 (AT_INIT): Likewise.
9068 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9069 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9070 AS_SHELL_SANITIZE.
9072 Use this M4sh to generate Autoconf's shell scripts.
9074 * tests/wrapsh.as: New, precursor of wrapsh.in.
9075 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9076 on Autotest and M4sh.
9077 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9078 (wrapsh.in): New target.

9087 2002-04-09 Andreas Schwab <schwab@suse.de>
9089 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9090 ac_top_builddir when setting ac_abs_top_builddir.
9092 2002-04-06 Kevin Ryde <user42@zip.com.au>
9094 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9095 (Portable Shell): Cross reference to Systemology.
9097 2002-04-05 Akim Demaille <akim@epita.fr>
9099 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9100 directories when descending in a SUBDIRS.
9101 Reported by Ezra Peisach.
9103 2002-04-04 Andreas Schwab <schwab@suse.de>
9105 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9106 contains no literal separators.
9108 2002-04-03 Akim Demaille <akim@epita.fr>
9110 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9111 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9112 Use dnl, not the KILL diversion.
9113 Extracted from...
9114 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9115 (AC_CONFIG_LINKS): here.
9116 Adjust.
9117 Don't use the KILL diversion, as it kills spurious output, which
9118 results in failures being hidden.
9119 Use m4_defn where appropriate.
9120 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9121 after the second argument.
9122 Use m4_defn.
9123 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9124 syntax, as it is provided by M4sugar.
9125 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9127 2002-04-03 Andreas Schwab <schwab@suse.de>

9133 aclocal.

9140 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9141 (_AC_COMPILER_OBJEXT): Use them.
9142 Fixes Debian #138666.
9144 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9146 Integrate AC_PROG_CC_STDC into AC_PROG_CC.

9149 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9150 (AC_PROG_CC): Call _AC_PROG_CC_STDC.

9164 2002-03-28 Kevin Ryde <user42@zip.com.au>
9166 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9167 to avoid versions of HP C which don't allow that.
9169 2002-03-27 Paul Eggert <eggert@twinsun.com>
9171 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.

9183 2002-03-25 Paul Eggert <eggert@twinsun.com>
9185 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9186 as POSIX requires, as it doesn't work with Zsh.
9187 * doc/autoconf.texi (Assignments): Document the problem.
9189 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9191 * doc/autoconf.texi (Limitations of Make): Mention more issue
9192 about VPATH, overriding of macros in sub-makes, and handling of
9193 SHELL.
9195 2002-03-21 Paul Eggert <eggert@twinsun.com>
9197 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9198 problem with here-document buffer boundaries.
9200 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9201 when reinvoking the shell, to work around problems with installers
9202 who put strange things like "cd" commands in their environments.
9204 2002-03-19 Akim Demaille <akim@epita.fr>

9220 2002-03-19 Akim Demaille <akim@epita.fr>
9222 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9224 2002-03-18 Paul Eggert <eggert@twinsun.com>
9226 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9227 (Limitations of Usual Tools): Add mkdir section.
9229 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9230 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9231 back on AS_DIRNAME to compute prefixes otherwise; this is
9232 roughly what mkinstalldirs does. That way, we need not have
9233 our own filename disassembler. The old disassembler did not
9234 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9236 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9237 Create at_test_all by a series of assignments,
9238 not by a single assignment of a long string. The latter causes ksh
9239 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9240 presumably because of a buffer overrun.
9242 2002-03-14 Paul Eggert <eggert@twinsun.com>
9244 * lib/autotest/general.m4 (at_times_skip):
9245 Renamed from at_times. Now a boolean.
9246 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9247 says 'times: not found'.

9297 aliases the actual variables, and modifications of the former
9298 affect the latter.

9302 * bin/autom4te.in (&handle_m4): Protect us from corrupted file

9333 parallel builds.
9335 2002-03-04 Akim Demaille <akim@epita.fr>
9337 * doc/autoconf.texi (Transforming Names): Equality between target
9338 and host is irrelevant.
9339 (Specifying Names, Canonicalizing): Remove all references to the
9340 backward compatibility hooks. Rather, collect them all into...
9341 (Hosts and Cross-Compilation): this new section.
9342 * doc/install.texi (System Type): Ditto.
9343 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9344 that `--host' implies cross-compilation.
9346 2002-03-04 Akim Demaille <akim@epita.fr>
9348 * doc/autoconf.texi (Evaluation Macros): New.
9349 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9350 useless.
9351 (_m4_foreach): Define the variant with immediate evaluation so
9352 that it contains exactly the items, not an expression which
9353 evaluation is the current item.
9354 (m4_re_string, m4_re_word): Don't over quote them.
9356 2002-03-04 Akim Demaille <akim@epita.fr>
9358 Instead of having stacking `shift's evaluated at the end, let
9359 `foreach' loops immediately evaluate them.
9361 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9362 $*. This is the n-th time I change my mind, but hopefully this is
9363 the last...
9364 (m4_lquote): New.
9365 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9366 efficient.
9367 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9368 it was only a hack for m4_text_wrap.
9369 (m4_car2): Remove, replaced by...
9370 (m4_cdr): New.
9371 (_m4_foreach): Adjust.
9372 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9373 m4_bpatsubst for clarification.
9375 2002-03-04 Akim Demaille <akim@epita.fr>

9462 to this file.
9464 2002-02-05 Akim Demaille <akim@epita.fr>
9466 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

9483 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9484 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9486 2002-02-05 Akim Demaille <akim@epita.fr>
9488 * bin/autom4te.in (&parse_args): Implement `frozen files are
9489 optional are the sum of the previous files on the command line'.
9490 Also, pass `--reload-state=' on them, so...
9491 (handle_m4): don't.
9492 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9493 (M4sh): Rely on M4sugar.

9503 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9504 alphanumeric to `-' instead of `_'.
9506 2002-01-30 Akim Demaille <akim@epita.fr>
9508 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9509 for plain code, the other for cross-compilation code. The latter
9510 is now run with GCC only.

9523 so that aclocal 1.4 works.
9524 Reported by Alexandre Duret-Lutz and Larry Schmitt.

9528 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9529 needs an argument.
9531 2002-01-28 Akim Demaille <akim@epita.fr>
9533 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9534 AUTOTEST_PATH *after* it was set.
9535 Don't put `.' in the PATH: the user should be precise and `./' if
9536 needed. In addition, given that the test suite does some `cd', if
9537 `.' is in the path, the `tested programs' sections will report
9538 programs found in the test suite's directory, while during the
9539 tests (performed in their own directory), these programs are no
9540 longer visible. In other words, the results is confusing and
9541 useless.
9542 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9544 2002-01-24 Akim Demaille <akim@epita.fr>

9584 2002-01-21 Akim Demaille <akim@epita.fr>
9586 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9587 message on invalid options.
9588 * bin/autom4te.in (parse_args): Don't use
9589 Autoconf::General::getopt with non valid options.
9591 2002-01-17 Jim Meyering <meyering@lucent.com>
9593 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9594 $ac_cv_exeext so we don't use an old, invalid, cached value.
9596 2002-01-11 Akim Demaille <akim@epita.fr>

9608 package.m4, since is really depends upon configure.ac, not
9609 configure.
9610 * doc/autoconf.texi (testsuite Scripts): Adjust.
9611 * tests/Makefile.am (package.m4): New.
9612 EXTRA_DIST it since its a source.
9614 2002-01-06 Akim Demaille <akim@epita.fr>
9616 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9617 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9618 and PACKAGE_BUGREPORT from here...
9619 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9620 arguments.
9621 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9622 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9623 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9624 * tests/tools.at (autoheader): Adjust.
9625 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9627 2002-01-06 Akim Demaille <akim@epita.fr>

9646 2001-12-14 Akim Demaille <akim@epita.fr>
9648 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9649 trailing files, don't apply `-rf' to files which might not be
9650 created by configure (core, core.*, and *.core), but just `rm -f'.
9651 Suggested by Jonathan Kamens.
9653 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9655 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.

9690 Remove $filepath, useless.
9691 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@

9693 Split the input line on spaces and then look for tokens.
9694 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9695 because of `lex$U.$(OBJEXT)'.
9696 (&scan_files): Use "@list" instead of join.
9697 * doc/Makefile.am (CLEANFILES): Add *.fns.

9764 This patch implements a `long double' suggestion by Oliver Kiddle.
9766 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9767 static, to catch errors if the value isn't known at compile-time
9768 and the compiler supports dynamic arrays. Change its name from
9769 `_array_' to `test_array' to avoid potential name clashes.
9770 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9771 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9772 better than double. Catch a bug in GCC 2.95.2 x86.
9773 * doc/autoconf.texi (C Compiler): Document the above.
9774 * NEWS: Likewise.
9776 2001-11-13 Akim Demaille <akim@epita.fr>
9778 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9779 hand.
9780 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9782 2001-11-13 Akim Demaille <akim@epita.fr>
9784 * lib/autotest/general.m4 (AT_INIT): After having run the test
9785 group, go back to the initial directory, not to at_suite_dir.
9787 2001-11-13 Akim Demaille <akim@epita.fr>
9789 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9790 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9791 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9792 option.
9793 (AT_CHECK_CONFIGURE): Use absolute paths.
9794 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9795 The problem is still the old one: there is no means in M4 (that I
9796 know about) to create a defining macro, because there is no means
9797 to create `$1' etc., therefore, the defining macro ``swallows''
9798 all the arguments meant to the defined macro.
9800 2001-11-13 Akim Demaille <akim@epita.fr>
9802 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9803 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9804 configure.ac.
9805 * tests/aclocal.m4: Remove, as it is no longer used.
9807 2001-11-13 Akim Demaille <akim@epita.fr>
9809 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9810 variable names when referring to a single test group, or to
9811 `suite' when referring to the whole test suite.
9812 `at_last_test' is removed: m4 compute at_format itself.
9813 (at_stdout, at_stder1, at_stderr): New variables.
9814 (AT_CHECK): Use them.
9816 2001-11-13 Akim Demaille <akim@epita.fr>
9818 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9819 in PATH.
9820 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9821 Do it as soon as a test fails, don't wait till the end of the test
9822 suite.
9823 Don't remove $as_me.[0-9]*, since these files no longer exist.
9825 2001-11-13 Akim Demaille <akim@epita.fr>
9827 * tests/tools.at: Use absolute paths, since we are no longer run
9828 in place.
9830 2001-11-13 Akim Demaille <akim@epita.fr>
9832 Now that tests are running in their own private dir, there is no
9833 need to list the files to remove at the end of tests groups.
9835 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9836 (AT_data_files, at_data_files): Remove.
9837 (AT_CLEANUP, AT_DATA): Simplify.
9838 (AT_INIT): Adjust.
9839 Remove the group dir if !debug && !failed.
9840 * tests/atspecific.m4: Adjust.
9842 2001-11-13 Akim Demaille <akim@epita.fr>
9844 Start a new layout for Autotest: `testsuite' creates
9845 `testsuite.dir' in which the at-check-line etc. files are to be
9846 found, and `testsuite.dir/003' where the test group 3 is run.
9848 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9849 at_check_line_file, at_format, at_test_normalized, at_group_dir
9850 are new variables.
9851 Create the directories.
9852 Use absolute paths for at- files.
9853 (AT_CHECK): Adjust.
9855 2001-11-11 Michael Matz <matz@kde.org>
9857 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9858 (m4_car2): New.
9859 (m4_car): Properly quote arguments.
9861 2001-11-13 Akim Demaille <akim@epita.fr>
9863 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9864 with stricter rules on LIBOBJS.
9866 2001-11-12 Paul Eggert <eggert@twinsun.com>
9868 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9869 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9870 __PROTOTYPES too.
9872 2001-11-12 Akim Demaille <akim@epita.fr>
9874 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9876 2001-11-12 Akim Demaille <akim@epita.fr>
9878 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9879 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9880 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9881 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9882 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9883 specify to what the macro should be defined (typically to 1).
9885 2001-11-12 Akim Demaille <akim@epita.fr>
9887 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9888 From Jim Meyering.
9890 2001-11-12 Akim Demaille <akim@epita.fr>
9892 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9893 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9894 definition used by Automake where LEX is +/- "${missing} lex" and
9895 `missing' itself contains variables.
9897 2001-11-12 Akim Demaille <akim@epita.fr>
9899 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9900 Now that M4sh pushes BODY, the comments were output at the end of
9901 the test suites.
9903 2001-11-08 Akim Demaille <akim@epita.fr>
9905 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9906 that we can trace macros from aclocal.m4.
9907 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9908 obsoleted, and redirect to the former anyway.
9909 Reported by Ralf Corsepius.
9911 2001-11-08 Akim Demaille <akim@epita.fr>
9913 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9914 processed only if present.
9915 * tests/torture.at (Configuring subdirectories): Use autoreconf
9916 instead of successive calls to autoconf.
9917 Add a nonexistent subdirectory to exercise the patch above.
9918 Reported by Ralf Corsepius.
9920 2001-11-08 Kevin Ryde <user42@zip.com.au>
9922 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9923 doesn't accept .S files.
9925 2001-11-07 Akim Demaille <akim@epita.fr>
9927 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9928 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9929 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9930 * bin/autom4te.in (warn_forbidden): New.
9931 (handle_output): Use it.
9932 Read m4_pattern_forbid with messages.
9934 2001-11-05 Akim Demaille <akim@epita.fr>
9936 * bin/autom4te.in (--normalize): Remove.
9937 * lib/autom4te.in: Adjust.
9939 2001-11-05 Akim Demaille <akim@epita.fr>
9941 * tests/Makefile.am (testsuite): Rename this target as...
9942 ($(TESTSUITE)): this.
9943 From Nicolas Joly.
9945 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9947 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9948 the --prefix option, also remove it's argument.
9950 2001-11-05 Akim Demaille <akim@epita.fr>
9952 * doc/autoconf.texi (testsuite Invocation): Update.
9953 (Writing testsuite.at): Update.
9955 2001-11-03 Akim Demaille <akim@epita.fr>
9957 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9959 2001-11-03 Akim Demaille <akim@epita.fr>
9961 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9962 (&file_name_is_absolute): New, wrappers around routines from
9963 File::Spec.
9964 Use and export them.
9965 (&find_configure_ac): Optionally take a directory where to look at.
9966 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9967 the arguments.
9968 Default @ARGV to `.', not find_configure_ac.
9969 (&autoreconf): Argument is a directory.
9970 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9971 * doc/autoconf.texi (autoreconf Invocation): Update.
9973 2001-11-03 Akim Demaille <akim@epita.fr>
9975 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9976 (@export_forward_subs): New.
9977 Add basename, dirname, and fileparse.
9978 (@EXPORT): Adjust.
9979 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9980 Don't look for aclocal flags if we already know aclocal is not
9981 used.
9982 Move aclocal.m4t only if it exists.
9983 Reported by Ezra Peisach.
9985 2001-11-03 Akim Demaille <akim@epita.fr>
9987 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9988 passed on command line, defaulting to ./configure.ac if present.
9989 (&maybe_autoreconf, File::Find): Remove, unused.
9990 (&autoreconf): If autoconf is not used, don't try to trace.
9992 2001-11-02 Akim Demaille <akim@epita.fr>
9994 * configure.ac: Bump to 2.52g.
9996 2001-11-02 Akim Demaille <akim@epita.fr>
9998 Version 2.52f.
10000 2001-11-02 Akim Demaille <akim@epita.fr>
10002 * config/config.guess, config/config.sub, doc/standards.texi:
10003 * config/lispdir.m4: Update from masters.
10004 * configure.ac: Bump to 2.52f.
10006 2001-11-02 Akim Demaille <akim@epita.fr>
10008 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10009 Don't run aclocal when aclocal.m4 is not from aclocal.
10010 From Ezra Peisach.
10011 Don't run libtoolize and gettextize if --install is not given.
10013 2001-11-01 Paul Eggert <eggert@twinsun.com>
10015 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10016 be invoked before _AS_LINENO_PREPARE.
10017 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10018 than character ranges.
10020 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10021 invoking AS_BASENAME. Set the locale variables to 'C' if
10022 possible, as POSIX requires this to get the traditional
10023 behavior.
10024 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10026 2001-10-31 Paul Eggert <eggert@twinsun.com>
10028 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10029 with {}, as that triggers a bug in Bash 2.05.
10031 (_AS_LINENO_PREPARE): Use Sed rather than
10032 Awk. Fix the sed prepass to work even if there are multiple
10033 instances of $LINENO on the same line. Do not substitute for
10034 other variables like $LINENOT. Do not check file dates; such a
10035 check is unreliable on sufficiently fast machines, and removing
10036 the check makes the code simpler and more reliable. Check for
10037 output and chmod failures.
10039 * doc/autoconf.texi (Special Shell Variables): Document
10040 the above.
10042 2001-10-31 Akim Demaille <akim@epita.fr>
10044 * tests/Makefile.am (atconfig): Remove this target, Automake
10045 handles it now.
10047 2001-10-31 Akim Demaille <akim@epita.fr>
10049 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10050 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10051 provided, while it is optional.
10052 * configure.ac: Adjust.
10054 2001-10-26 Paul Eggert <eggert@twinsun.com>
10056 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10057 lib/Autom4te/Struct.pm:
10058 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10059 with 5.005_02.
10061 * doc/autoconf.texi (Special Shell Variables): Document some
10062 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10064 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10065 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10066 eval $LINENO is not portable in practice.
10068 2001-10-24 Akim Demaille <akim@epita.fr>
10070 * lib/Autom4te/General.pm (backname): New.
10072 2001-10-24 Akim Demaille <akim@epita.fr>
10074 * m4/: Remove, merged into...
10075 * config/: here.
10077 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10079 * doc/autoconf.texi (Shellology): Mention the problems with bash
10080 2.05's use of ANSI quoting in its `set' builtin.
10082 2001-10-22 Paul Eggert <eggert@twinsun.com>
10084 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10085 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10086 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10087 POSIX decided to standardize on the int flavor of strerror_r.
10088 Always do char* test, as there's no reason not to.
10089 Assign to a char* var, to catch strerror_r that returns int*.
10091 * doc/autoconf.texi (Particular Functions):
10092 Document the above changes. Also, document the fact that
10093 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10095 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10097 2001-10-20 Akim Demaille <akim@epita.fr>
10099 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10100 the executable was missing from the log.
10102 2001-10-20 Akim Demaille <akim@epita.fr>
10104 * lib/Autom4te/General.pm (&update_file): If destination is
10105 unchanged, remove the source.
10106 (&up_to_date_p): Don't be verbose, be debug.
10107 * bin/autoreconf.in: No longer support --m4dir.
10108 (&autoreconf): Display the full path of the configure.ac we are
10109 studying.
10110 Trace it only once.
10111 Be sure to honor --force with gettextize.
10112 Always run aclocal.
10113 * doc/autoconf.texi: Adjust.
10115 2001-10-20 Akim Demaille <akim@epita.fr>
10117 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10118 Remove, dead.
10119 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10120 `intl' is already present, as it refuses unless --force.
10121 (&parse_args): Use -I, --include instead of the old Autoconf
10122 options.
10123 ($localdir, $autoconf_dir): Remove.
10124 (@include): New.
10125 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10127 2001-10-19 Jens Petersen <petersen@redhat.com>
10129 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
10130 * doc/autoconf.texi (Particular Programs): Likewise.
10132 2001-10-19 Akim Demaille <akim@epita.fr>
10134 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
10135 file in @configure_input@.
10136 Don't mention `automatically' in addition to `generated'.
10137 * tests/torture.at (#define header templates): Adjust.
10139 2001-10-19 Akim Demaille <akim@epita.fr>
10141 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10142 comment, explain how to install automatic mode selection.
10143 From Russ Allbery.
10145 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10147 * bin/autoreconf.in (autoreconf): Display the path to the
10148 configure.ac being studied.
10150 2001-10-18 Paul Eggert <eggert@twinsun.com>
10152 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10153 long, to work around a bug in the HP C compiler version HP92453-01
10154 B.11.11.23709.GP.
10156 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10157 (AS_BASENAME_EXPR): New macro.
10158 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10159 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10160 and fall back on 'sed' only if the other two fail. This makes
10161 AS_BASENAME act more like AS_DIRNAME.
10162 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10163 contains white space.
10164 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10165 Use AS_DIRNAME, since I think it's now DOS-friendly.
10166 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10167 Allow "dirname //FOO" to return either / or //, as POSIX allows
10168 either behavior.
10170 2001-10-10 Akim Demaille <akim@epita.fr>
10172 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
10173 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
10174 From Eric Sharkey.
10176 2001-10-10 Akim Demaille <akim@epita.fr>
10178 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10179 m4_define, since...
10180 (_AS_ECHO_N): AS_REQUIREs it.
10182 2001-10-10 Akim Demaille <akim@epita.fr>
10184 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
10185 (AC_INCLUDES_DEFAULT): Move to...
10186 * lib/autoconf/headers.m4: here.
10187 * lib/autoconf/types.m4: Comment changes.
10188 * doc/autoconf.texi: Specify where the default includes are used

10193 * lib/autoconf/autoconf.m4 (m4_patsubst, m4_regexp): New
10194 transition code.
10196 2001-10-08 Akim Demaille <akim@epita.fr>
10198 * bin/autoreconf.in (&autoreconf): Remove debugging code.
10199 (&parse_args): Pass verbosity/debugging options to subtools when
10200 --debug, not when --verbose.
10201 * lib/autom4te.in (Autoreconf-preselections): New.
10202 (Autoconf): Use it.
10204 2001-10-08 Akim Demaille <akim@epita.fr>
10206 * bin/autoreconf.in (autoreconf): Run libtoolize when appropriate.
10208 2001-10-08 Akim Demaille <akim@epita.fr>

10213 2001-10-08 Akim Demaille <akim@epita.fr>
10215 * tests/tools.at (AT_CHECK_PERL_SYNTAX): Check autoreconf.
10216 (Syntax of the shell scripts): Don't.
10217 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't
10218 bother with $force since...
10219 * lib/Autom4te/General.pm: does.
10221 2001-10-08 Akim Demaille <akim@epita.fr>
10223 * bin/autoreconf.in: Rewrite in Perl.
10224 * configure.ac: Adjust.

10314 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
10315 doesn't exist. Remove *.tmp, as a .tmp file is created during the

10399 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.

10431 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
10432 (AC_PROG_CPP requires AC_PROG_CC): here and...
10433 * tests/fortran.at (GNU Fortran 77): there.
10434 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10435 AC_TRY_RUN is about compilation, not shell commands.
10436 (Test Programs): AC_TRY_RUN works as used to be advertised.
10438 2001-09-27 Akim Demaille <akim@epita.fr>
10440 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10441 Raja R Harinath:
10442 Be sure to detect when $LINENO always returns the same value.
10443 Look for the original script, basename($0) is certainly not
10444 enough.
10445 Pass the CLI arguments to `$as_me.lineno'.

10466 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
10467 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10468 builddir, buildpath, top_builddir, and top_buildpath.
10469 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10470 the current directory.

10487 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
10488 * configure.ac: Build the position independent wrappers.
10490 * man/Makefile.am: Now that test wrappers are position
10491 independent, use them and drop dark envvar magic.

10495 * doc/autoconf.texi (Common Shell Constructs): Rename as...
10496 (Programming in M4sh): this.

10542 2001-09-22 Akim Demaille <akim@epita.fr>

10547 `$LINENO' support replacement when not supported.
10548 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10549 them explicitly to be sure they are not output before this section

10559 character (u: -> ue) in a code comment.
10560 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know

10580 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

10587 * lib/autotest/general.m4: Replace occurrences of ':' in
10588 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10590 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10592 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10593 arguments. Fixed a typo.
10595 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10597 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up

10609 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10611 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10612 already have $file). Set output files to binary mode (helps avoid
10613 CR issues on DOSish systems).
10615 2001-09-19 Akim Demaille <akim@epita.fr>
10617 * lib/autotest/general.m4: Englishoes.
10618 From Tim Van Holder and Alexey Mahotkin.
10620 2001-09-18 Paul Eggert <eggert@twinsun.com>
10622 * doc/autoconf.texi (Common Shell Constructs): New node,
10623 documenting AS_DIRNAME.
10624 (Limitations of Usual Tools): Refer to it when discussing dirname.
10625 Also, update discussion of POSIX standard to reflect latest draft.
10627 * lib/autoconf/c.m4:
10628 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10630 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10631 Do not pass a first argument with leading '-'
10632 to expr, by parenthesizing initial integers that might be negative.
10634 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10635 now merely checks whether it is an error to pass an argument
10636 to getpgrp.
10638 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10639 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10640 whether it is a (compile-time) error to pass an argument to
10641 getpgrp. This simpler test supports the revised documentation,
10642 and is all that AC_FUNC_GETPGRP's users really need.
10644 2001-09-18 Akim Demaille <akim@epita.fr>

10656 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10657 correctly.
10658 Add test for AS_BASENAME.
10659 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10660 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10661 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10662 * tests/base.at: Fixed the expected responses. The old ones were
10663 one line out...
10664 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10665 the documentation claims it should (and how it behaved in 2.13).
10667 2001-09-18 Akim Demaille <akim@epita.fr>
10669 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

10674 No longer to be shipped.

10678 Use `m4_PACKAGE_STRING'.
10679 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10680 the only optional argument is the name of the test suite.
10681 Expect `package.m4' to define the package signature.
10682 * lib/autom4te.in (Autotest): Add `package.m4?'.
10683 * tests/Makefile.am (package.m4): New.
10684 * tests/suite.at: ifnames is a victim.

10691 program version string doesn't match the package's.
10692 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space

10703 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10704 Always include <stdio.h> and <stdlib.h>. Evaluate
10705 the expression in an extra function before these includes. Call
10706 fprintf "%d" only after ensuring the argument is of type 'int'.
10707 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10709 2001-09-17 Paul Eggert <eggert@twinsun.com>
10711 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10712 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10713 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10714 when they don't exist.
10716 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
10717 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
10718 need it.
10720 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10721 version with the version used by fileutils 4.1, except use
10722 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
10723 we don't need it.
10725 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
10727 2001-09-13 Akim Demaille <akim@epita.fr>
10729 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
10730 _first_.

10767 * lib/autotest/general.m4 (AT_INIT): Create and remove
10768 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

10773 * tests/mktests.sh: Don't output banners for empty test files.

10825 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

10841 2001-09-07 Akim Demaille <akim@epita.fr>
10843 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
10844 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
10845 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
10846 related variables into `at_package_*'.

10858 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,

10861 Adjust PATH computation.
10862 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

10879 2001-09-05 Akim Demaille <akim@epita.fr>
10881 Be ready to handle filenames as stupid as `dnl.at', for if even
10882 the maintainer is dumb enough to do that...
10884 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10885 excellence in M4 quotation: consider `__file__' is active.
10887 And BTW, when invoking m4, pass the --include in the right order:
10888 the wrong one.
10890 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
10891 4m.

10915 CVS GNU M4 doesn't like `undefine(undefined)'.
10917 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
10918 New, extracted from main.
10919 Use IO::File wherever possible.
10920 (input.m4): Be constant, use -I instead of hard coding $tmp.
10921 Therefore be a quoted heredoc.
10922 Don't invoke `_au_disable', since ac was not loaded, but just
10923 `unm4.m4'.
10925 2001-08-31 Akim Demaille <akim@epita.fr>
10927 Version 2.52d.

10950 2001-08-31 Akim Demaille <akim@epita.fr>
10952 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10953 (testsuite Scripts): There is no such thing as `atconfig.in'.
10954 And actually one diagram is missing: test suite runtime.
10956 2001-08-31 Akim Demaille <akim@epita.fr>
10958 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10959 inverse order.
10961 2001-08-31 Akim Demaille <akim@epita.fr>
10963 * bin/autoupdate.in (@include): `installcheck' revealed the path
10964 to m4sugar was lacking!
10966 2001-08-31 Akim Demaille <akim@epita.fr>
10968 * man/Makefile.am (.x.1): We really have to pass
10969 autom4te_perllibdir.
10971 2001-08-31 Akim Demaille <akim@epita.fr>
10973 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
10974 debug scripts, in particular passing explicitly listed tests to
10975 run is stupid.
10977 2001-08-31 Akim Demaille <akim@epita.fr>
10979 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10980 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10981 Use directly autom4te, not autoconf.

10984 2001-08-31 Akim Demaille <akim@epita.fr>
10986 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.

10995 * bin/autom4te.in (&parse_args): Die on unknown languages.
10996 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
10997 need for autoconf.
10998 Promote --include over --macrodir and other obsolete options.
11000 2001-08-31 Akim Demaille <akim@epita.fr>
11002 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

11005 `print $out' doesn't print `$_' but `$out'.
11006 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11007 (autoheader): Pass --force since the test suite goes too fast for
11008 the time stamps.
11009 Adjust to the new autoheader messages.
11011 2001-08-31 Akim Demaille <akim@epita.fr>
11013 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11014 Check the completeness of the #template.

11023 Drop AC_MACRODIR dead for real.
11024 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11025 `autoheader: `config.hin' is created'.
11026 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11028 2001-08-31 Akim Demaille <akim@epita.fr>
11030 * bin/autoheader.in: Rewrite in Perl.

11033 2001-08-31 Akim Demaille <akim@epita.fr>
11035 * bin/autoconf.in (--include, -I): New option.
11036 Map --localdir, --autoconf-dir onto it.
11037 Forward autom4te's options instead of interpreting them.
11038 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11039 There is no such envvar since the inception of autom4te.cfg.
11040 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11041 * bin/autoupdate.in: Adjust, and perform more control.
11042 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.

11045 2001-08-31 Akim Demaille <akim@epita.fr>
11047 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11048 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11049 optionally `FILE'.
11050 Use -e, not -f, since /dev/null for instance is OK.
11051 (&parse_args): Adjust.
11052 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11054 2001-08-31 Akim Demaille <akim@epita.fr>
11056 * configure.ac: Also find tested executables in bin.
11057 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11058 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11059 installed peer executables, only PATH is allowed to resolve it.
11060 Pass `autoconf_dir' via options, not via invisible envvars.
11061 * lib/Autom4te/General.pm (&find_peer): Remove.
11062 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11063 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11064 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11065 find the executables for it.
11066 * tests/Makefile.am: Major cleanup. Too lazy to document...
11067 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11068 We only need PERL.
11069 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11070 indeed related to running the test suite, while passing
11071 --autoconf-dir and others is related to running non installed
11072 Autoconf executables. So don't do that, leave it to...
11073 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11074 * tests/autoscan: New.
11075 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11076 refer to library files: rely on --language.
11078 2001-08-29 Akim Demaille <akim@epita.fr>
11080 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

11083 2001-08-29 Akim Demaille <akim@epita.fr>
11085 * doc/autoconf.texi: Strip the @nodes.
11086 Suggested by Paul Eggert.

11089 2001-08-29 Akim Demaille <akim@epita.fr>
11091 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11092 Suggested by Paul Eggert.
11094 2001-08-29 Akim Demaille <akim@epita.fr>
11096 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11097 download in a tmp dir.
11099 2001-08-29 Akim Demaille <akim@epita.fr>
11101 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
11102 case insensitive OSes out there :(

11112 (&parse_args): Support --mode, --set, and --melt.
11113 * bin/autoconf.in: Simplify and adjust.
11114 * tests/Makefile.am (AUTOMAKE): Use --set.
11115 * tests/atlocal.in: Adjust.
11116 * BUGS: distcheck and check are weak.
11118 2001-08-29 Akim Demaille <akim@epita.fr>
11120 * lib/autotest/general.m4: Use
11121 foo=`(command) 2>/dev/null`
11122 not
11123 foo=`command` 2>/dev/null
11124 (at-devnull): Rename as...
11125 (AT-devnull): this.
11126 (--clean): Remove AT-* files too.
11127 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11128 Reported by Nicolas Joly.
11130 2001-08-28 Akim Demaille <akim@epita.fr>

11571 is in the src tree.
11573 2001-08-15 Akim Demaille <akim@epita.fr>
11575 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
11576 don't waste time running `autoupdate --version' works.
11577 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
11579 2001-08-13 Akim Demaille <akim@epita.fr>

11599 * tests/semantics.at (AC_C_BIGENDIAN): Explicitelly save and load
11600 endianness for comparison instead of relying on AT_CHECK_ENV.
11602 2001-08-11 Paul Eggert <eggert@twinsun.com>
11604 * doc/autoconf.texi, doc/install.texi: Add a copyright notice
11605 to the INSTALL file.
11607 2001-08-11 Paul Eggert <eggert@twinsun.com>

11634 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11636 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11638 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11640 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11641 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11642 * doc/autoconf.texi (C Compiler Characteristics): Update
11643 documentation for AC_C_BIGENDIAN.
11645 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11647 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11648 magic values from an object file when cross-compiling.
11649 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11651 2001-08-10 Akim Demaille <akim@epita.fr>
11653 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11654 effects.
11655 Suggested by Russ Allbery.
11657 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11659 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11660 current $prefix to the sub-configures.
11662 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11664 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11665 extension (needed on BeOS). Reported by Guido van Rossum.
11667 2001-08-09 Akim Demaille <akim@epita.fr>
11669 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11671 2001-08-07 Akim Demaille <akim@epita.fr>
11673 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11674 removed.
11675 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11676 No need to remove the files before and after the each test, before
11677 each test and at the end of the suite is enough.
11678 Display only the children `times', not the shell's.
11679 If the test failed or was skipped, at-times is not available.
11681 2001-08-07 Akim Demaille <akim@epita.fr>
11683 Always produce testsuite.log, including when there are no
11684 failures. This helps getting information on skipped tests, and
11685 duration of the tests. Err, implement the latter btw.
11687 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11688 Dump information on the first run of each test.
11689 (AT_CLEANUP): Create `at-times' containing the duration of the
11690 test group.
11692 2001-08-07 Akim Demaille <akim@epita.fr>
11694 The use of `dumpstat' revealed that `len' was used although it
11695 should not. m4_text_wrap was using it, but in the Autoconf world
11696 where it is legal. Hence (i) test M4sh in its own world, not
11697 Autoconf's, and (ii), ahem, fix the bug :)
11699 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11700 does not like `' instead of [].
11701 (AT_INIT): Forbid `^_?AT_'.
11702 And don't output such tokens.
11703 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11704 `script.as', and `autom4te.cache'.
11705 Remove `empty' and `macro' which are no longer used.
11706 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11707 * tests/m4sugar.at: Use it.
11708 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11710 2001-08-07 Akim Demaille <akim@epita.fr>
11712 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11714 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11716 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11718 2001-08-04 Akim Demaille <akim@epita.fr>
11720 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11721 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11722 AC_TRY_LINK.
11723 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11724 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11725 (AC_F77_MAIN): Likewise.
11727 2001-08-04 Akim Demaille <akim@epita.fr>
11729 Don't rely on M4sugar outputting the patterns in files, since we
11730 might process the output _without_ running m4, hence without these
11731 files.
11733 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11734 * bin/autom4te.in (@Request::includes): Remove, unused.
11735 (@Request::source): Rename as...
11736 (@Request::input): this.
11737 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11738 (&handle_output): Fetch the patterns from the traces.
11739 `$forbidden' and `$allowed' are constant: use m//o.
11740 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11741 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11743 2001-08-04 Akim Demaille <akim@epita.fr>
11745 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11746 autoconf', i.e., in addition to caching traces, cache the output.
11748 * bin/autom4te.in (Request::cache): Rename as...
11749 (Request::id): this.
11750 ($cache, $icache, $tcache, $ocache): New.
11751 (&handle_m4): Save M4 output in the cache instead of $tmp.
11752 (&handle_output): Adjust.
11753 (&up_to_date_p): Check that the output cache is up to date too.
11754 (top level): Run `&handle_m4' iff force or the cache is invalid.
11755 Run `&handle_output' if the output cache is more recent.
11757 2001-08-04 Akim Demaille <akim@epita.fr>
11759 * bin/autom4te.in ($force): New.
11760 (&parse_args, &print_usage): -f, --force is a new option.
11761 (&handle_output): CPP directives might have spaces after `#'.
11762 (&parse_args): The first file only can be frozen.
11764 2001-08-04 Akim Demaille <akim@epita.fr>
11766 Don't let autom4te compute the `include' traces several times:
11767 first check that the trace cache file is up to date, and then
11768 compare its timestamp with that of the output.
11770 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11771 the preamble. Don't require 5.005 as Autom4te::General does it,
11772 and better yet (use `use', not `require'!).
11773 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11774 Class::Struct as Autom4te::Struct.
11775 * lib/Autom4te/General.pm (File::stat): Use it.
11776 (&mtime): New, export it.
11777 * bin/autom4te.in: Use it.
11778 Declare `$req' is invalid if it is outdated.
11779 Don't declare it valid before saving it if something went wrong.
11781 2001-08-04 Akim Demaille <akim@epita.fr>
11783 Autom4te shall not encode Autoconf data, and preselecting traces
11784 must be proposed to the users.
11786 * bin/autom4te.in (@required_trace): Remove.
11787 (@preselect): New.
11788 (&parse_args, &print_usage): -p, --preselect is a new option.
11789 (&up_to_date_p): Adjust.
11790 * bin/autoconf.in: Preselect some Autoconf macros.
11792 2001-08-04 Akim Demaille <akim@epita.fr>
11794 * tests/tools.at (autoconf --trace: user macros): Check traces on
11795 macros invoked without arguments, and macros invoked with multiple
11796 lines arguments.
11798 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11800 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11801 arguments.
11803 2001-08-03 Akim Demaille <akim@epita.fr>
11805 * bin/autoconf.in ($@): Work around the usual sh bug.
11806 From Nicolas Joly.
11808 2001-08-03 Akim Demaille <akim@epita.fr>
11810 Clean up the handling of the M4 builtins tracing exception.
11812 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11813 trace requests.
11814 (@m4_builtins): Rename as...
11815 (@m4_builtin): this.
11816 (%m4_builtin_alternate_name): New.
11817 (&parse_args): Complete the trace requests with alternate names.
11818 (&handle_traces): Hence no longer do it here.
11819 (&trace_requests): Remove, unused.
11821 2001-08-03 Akim Demaille <akim@epita.fr>
11823 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11824 m4_if, and m4_wrap.
11826 2001-08-03 Akim Demaille <akim@epita.fr>
11828 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11829 (m4_divert_pop): Dump the whole diversion stack when a diversion
11830 mismatch happens.
11831 * bin/autom4te.in (&handle_output): Remember of the first
11832 occurrence of a possibly undefined macro, not the last.
11833 Complain about the possibly undefined macros in the same order as
11834 the appear in the output.
11835 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11836 * tests/tools.at (autoconf: forbidden tokens, basic)
11837 (autoconf: forbidden tokens, exceptions): No longer sort
11838 autoconf's stderr, as it is now deterministic.
11839 Check that `dnl' is caught.
11841 2001-08-01 Akim Demaille <akim@epita.fr>
11843 * configure.ac: Bump to 2.52c.
11845 2001-08-01 Akim Demaille <akim@epita.fr>

11855 2001-08-01 Akim Demaille <akim@epita.fr>
11857 * lib/Autom4te/General.pm: Use `carp' and `croak', not `warn' and
11858 `die'.
11859 (&END): New.
11860 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11861 `END', as `Autom4te::General::END' will be triggered.
11862 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11863 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12298 cross-language link tests can be performed successfully.
12299 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12300 after $LIBS, for consistency; this should be the general rule since
