3 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
4 (AC_C_VOLATILE):
5 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
6 These macros are obsolescent and new applications shouldn't need them.
7 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
8 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
9 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
10 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
11 (AC_FUNC_VPRINTF): Likewise.
12 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
13 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
14 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
16 * doc/autoconf.texi (Setting Output Variables): Mention that
17 @VAR1@VAR2 has unspecified behavior. Problem reported by
18 Ralf Wildenhues.
19 * NEWS: Mention this.
21 * Makefile.am: Put only a single '#' into the copyright notice,
22 so that it's also present in the output file. Standardize wording
23 in makefile copyright notices to match GNU coding standards.
24 * bin/Makefile.am: Likewise.
25 * doc/Makefile.am: Likewise.
26 * lib/Makefile.am: Likewise.
27 * lib/freeze.mk: Likewise.
28 * lib/autoconf/Makefile.am: Likewise.
29 * lib/autoscan/Makefile.am: Likewise.
30 * lib/autotest/Makefile.am: Likewise.
31 * lib/m4sugar/Makefile.am: Likewise.
32 * man/Makefile.am: Likewise.
33 * tests/Makefile.am: Likewise.
34 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
35 one-line file.
37 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
39 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
40 in the sed script that mangles the awk script: delete up to the
41 first exclamation mark only.
42 * tests/torture.at (Substitute and define special characters):
43 Test '!' too.
45 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
47 Rewrite config files generation: avoid quadratic growth in
48 the number of substituted variables by using awk instead of sed
49 for the bulk of the substitutions.
50 * NEWS: Mention this.
51 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
52 forbidden in the output (and thus input) file.
53 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
54 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
55 generate just one large awk script for substitutions,
56 eliminating much of the earlier complexity, while adding some
57 new complexity. Only expand the substitution templates at
58 configure time, for smaller configure script size. If
59 _AC_SUBST_FILES are used, test 'awk' for working getline support
60 at config.status time. If absent, interpolate through the
61 shell. The awk script was written with much help
62 from Paolo Bonzini and Paul Eggert.
63 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
64 (_AC_SED_FRAG_NUM): Likewise.
65 (_AC_SUBST_CMDS): Renamed from...
66 (_AC_SED_CMDS): ...this.
67 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
68 * tests/torture.at (Substitute a 2000-byte string): Also
69 substitute a line with 1000 words, and a variable with several
70 long lines.
71 (Substitute and define special characters): Test awk special
72 characters, and put substitution input strings `@foo@' in the
73 output, to test that no recursion happens; test several other
74 combinations from Paolo Bonzini.
76 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
78 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
79 that replaced echo with AS_ECHO where this wasn't necessary.
80 Problem reportd by Ralf Wildenhues.
81 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
82 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
83 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
85 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
87 * lib/freeze.mk (GREP): Removed, no need to initialize this.
89 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
91 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
92 that traditional Awk lacks 3-arg "split". It has it.
93 Mention that FS must be a single character, and a few other
94 99-byte limits of traditional Awk.
95 Mention that if (i in a) doesn't work with traditional Awk.
97 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
99 * tests/autotest.at (BSx641-newline in command):
100 (BS-BS-newline in command, BSx640-newline in command):
101 (Newline-CODE-BS-newline in command):
102 (Single-quote-BS-newline in command):
103 (Single-quote-newline-BS-newline in command):
104 Use printf '%s\n' instead of echo, for portability to hosts
105 where echo interprets backslashes. This will break on hosts
106 that lack printf, but for now let's assume all such hosts
107 are dead (if not, we should get reports of test failures).
109 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
111 'echo' has some portability problems, when given a first argument
112 with a leading '-', or when given any argument containing '\'.
113 Avoid using 'echo' in these cases.
114 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
115 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
116 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
117 * lib/autotest/general.m4 (AT_INIT): Likewise.
118 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
119 argument might be unportable.
120 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
121 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
122 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
123 (_AC_FC_LIBRARY_LDFLAGS): Likewise.
124 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Likewise.
125 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE, _AC_INIT_PREPARE):
126 (_AC_ARG_VAR_VALIDATE, AC_ARG_PROGRAM, _AC_MSG_LOG_CONFTEST):
127 (AC_RUN_LOG, _AC_RUN_IFELSE, _AC_LIBOBJS_NORMALIZE): Likewise.
128 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
129 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Likewise.
130 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH):
131 (AC_PROG_MAKE_SET): Likewise.
132 * lib/autoconf/status.m4 (_AC_SRCDIRS, _AC_OUTPUT_HEADER):
133 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
134 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
135 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
136 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):
137 (_AS_BASENAME_SED, _AS_DIRNAME_SED, AS_MKDIR_P, AS_TMPDIR, AS_UNAME):
138 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
139 * bin/autoconf.as: Redo verbose flag implementation, as the old
140 scheme wouldn't work with AS_ECHO.
141 * lib/autotest/general.m4 (AT_INIT): Likewise.
142 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
143 Don't use ECHO_T, since ECHO_N is now reliable.
144 * lib/autotest/general.m4 (AT_INIT): Likewise.
145 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
146 rather than using a here-document to put the script into a file.
147 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
148 use AS_ECHO.
149 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
150 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
151 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
152 bug, but we might as well stop using ECHO_N and ECHO_C internally.
153 * lib/autotest/general.m4 (AT_SETUP): Likewise.
154 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
155 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
156 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
157 operand, as AS_ECHO requires. Avoid double file name expansion.
158 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
159 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
160 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
161 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
162 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
163 Double-quote strings that would otherwise contain M4 comments.
164 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
166 * configure.ac (AC_INIT): Bump to 2.61a.
167 * NEWS: Likewise.
169 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
171 Version 2.61.
173 * configure.ac (AC_INIT): Bump to 2.61.
174 * NEWS: Likewise.
176 * tests/autotest.at (Macro with backslash in a test title):
177 Comment out for now, as this tests neither fails nor passes
178 reliably. Problem reported by Ralf Wildenhues.
180 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
182 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
183 in previous change, which caused test failures.
185 2006-11-16 Stepan Kasal <kasal@ucw.cz>
187 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
188 code for --enable, --disable, --with, and --without to...
189 (_AC_INIT_PARSE_ENABLE): ... a new macro.
190 * doc/autoconf.texi (Package Options):
191 * NEWS: Document that AC_ARG_ENABLE allows dots, too.
193 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>

234 * build-aux/texinfo.tex (\dopdfimage): look for png, jpg/jpeg/JPG, and
235 as well as pdf images, since they are supported in pdftex with
236 no further ado.
238 2006-11-05 Karl Berry <karl@gnu.org>
240 * doc/texinfo.tex (Image Syntax): don't mention GIF any more.

262 and Paul Eggert <eggert@cs.ucla.edu>
264 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
265 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
266 ./micro-suite.
268 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
270 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
271 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
272 Imported from a similar patch to gnulib by Bruno Haible.
274 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
276 * NEWS: New macros AC_C_FLEXIBLE_ARRAY_MEMBER, AC_C_VARARRAYS.

289 * tests/torture.at (Configuring subdirectories): Do not skip
290 Automake 1.10 nor future Automake 11.1 (sic).
292 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
293 and Stepan Kasal <kasal@ucw.cz>
295 Handle special characters in test case titles correctly.
296 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
297 properly.
298 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
299 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
300 argument. Extend to check titles printed by ./micro-suite and
301 ./micro-suite -l and the title in micro-suite.log.
302 (Backquote in a test title,
303 Single-quote in a test title,
304 Double-quote in a test title): Don't expect failure anymore.
305 (Backslash in a test title): Put a non-whitespace character after the
306 backslash so that Bourne shells might actually see it as an escape
307 sequence.
308 (Brackets in a test title,
309 Pound in a test title,
310 Comma in a test title,
311 Quoted Macro in a test title,
312 Macro in a test title,
313 Macro with single-quote in a test title): New tests.
314 (Macro with backquote in a test title,
315 Macro with double-quote in a test title,
316 Macro with backslash in a test title): New tests expected to fail.
317 * tests/torture.at (#define header templates): M4-quote this title in
318 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
319 The visible effect was a stray [] in the testsuite output.
321 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
323 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
324 `trap ... 0' inside a function, for AIX sh.
326 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
328 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
329 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
330 5363) simply issues a warning when dividing by zero at compile
331 time. Problem reported by Elias Pipping.
333 2006-10-26 Eric Blake <ebb9@byu.net>
335 * THANKS: Update.
336 * doc/autoconf.texi (Evaluation Macros): Improve the example to
337 show effect on macros that expand with commas.
338 Reported by Joel E. Denny.
340 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
341 Also work with M4 1.4.8.

346 Jim Meyering.
348 2006-10-25 Stepan Kasal <kasal@ucw.cz>

351 `--force' always rewrites the output file.
353 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
355 * doc/autoconf.texi (Limitations of Usual Tools): Document that rm
356 needs operands on NetBSD 2.0.2. Problem reported by Bruno Haible.
358 2006-10-24 Stepan Kasal <kasal@ucw.cz>
360 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
362 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
364 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
365 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
366 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
367 reported by Nelson H. F. Beebe for Coreutils 6.4.
369 * tests/tools.at (autoconf --trace: user macros): Remove test
370 for tracing multiline macros, since m4 1.4.7a uses a different
371 way to number lines. Problem reported by Ralf Wildenhues.
373 2006-10-24 Stepan Kasal <kasal@ucw.cz>
375 * bin/autom4te.in (handle_m4): Do not redirect stdin to
376 /dev/null since the heuristics for interactive behaviour was
377 fixed in CVS m4.
379 * bin/autom4te.in: With --force, always refresh the output
380 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
382 * bin/autoconf.as: Fix the verbose message at the end.
384 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

397 * NEWS: Remove AC_CACHE_CHECK_INT.
398 * doc/autoconf.texi (Caching Results): Likewise.
399 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
400 AC_CACHE_CHECK_INT, since it's no longer public.
401 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
402 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
404 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
406 * doc/autoconf.texi (Limitations of Usual Tools): Fix two typos.
408 2006-10-19 Eric Blake <ebb9@byu.net>
410 * lib/m4sugar/m4sugar.m4 (m4_mkstemp): New macro.
411 (m4_maketemp): Avoid warnings with M4 1.9a.
412 * lib/emacs/autoconf-mode.el (autoconf-font-lock-keywords): Color
413 m4_mkstemp.
414 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.
415 * NEWS: Likewise.
417 2006-10-16 Eric Blake <ebb9@byu.net>
419 * doc/autoconf.texi (Setting Output Variables): Fix typo.
421 * bin/autoconf.as (version): Reword to match GNU Coding
422 Standards.
423 * bin/autoheader.in (version): Likewise.
424 * bin/autom4te.in (version): Likewise.
425 * bin/autoreconf.in (version): Likewise.
426 * bin/autoscan.in (version): Likewise.
427 * bin/autoupdate.in (version): Likewise.
428 * bin/ifnames.in (version): Likewise.
430 2006-10-14 Stepan Kasal <kasal@ucw.cz>
432 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
433 looking for special shell characters.
434 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
435 macro defined by AS_VAR_PUSHDEF before passing it as a
436 parameter.
437 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
438 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):
439 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_NEW, AC_CHECK_MEMBER):
440 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL):
441 (_AC_CHECK_HEADER_NEW, _AC_CHECK_HEADER_OLD, _AC_CHECK_HEADER_DIRENT):
442 Likewise.
443 * lib/autotest/general.m4 (AT_INIT): Quote parameters of
444 AS_VAR_* properly.
445 * tests/m4sh.at (AS_LITERAL_IF): New test.
447 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
449 (Imported from Automake.)
450 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
451 which incorrectly sets the mode of an existing destination
452 directory. In some cases the unpatched install-sh could do the
453 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
454 system. We hope this is rare in practice, but it's clearly worth
455 fixing. Problem reported by Alex Unleashed in
456 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
457 Also, don't bother to check for -m bugs unless we're using -m;
458 suggested by Stepan Kasal.
460 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
462 Import this change from Automake:

466 is enabled by default with gnu and gnits strictness.
467 Report from Bruno Haible.
469 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>
470 * lib/Autom4te/ChannelDefs.pm: Make -Wportability the default in

517 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

525 Report by IOhannes m zmoelnig <zmoelnig@iem.at>.
527 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
529 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
530 the NonStop platform.
531 * doc/autoconf.texi (Posix Variants): Likewise.
532 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
534 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
535 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
536 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
537 Use a better substitute, by inspecting the output of "ls"
538 rather than just using ":".
539 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
540 rather than AS_EXECUTABLE_P, since we needn't worry about
541 non-regular files here.
543 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
544 due to configuration hassles with this. See Tonya Underwood's report
545 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.
546 * doc/autoconf.texi (Special Shell Variables): Likewise.
548 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>

552 (_AS_DETECT_BETTER_SHELL): Don't look in /usr/bin/posix.
554 2006-10-11 Stepan Kasal <kasal@ucw.cz>
556 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the
557 initialization which is not inherited through the environment
558 (_AS_BOURNE_COMPATIBLE): ... to this new macro.

561 2006-10-09 Paul Eggert <eggert@cs.ucla.edu>
563 * doc/autoconf.texi (Limitations of Usual Tools): Describe
564 problems with mkdir -p -m.

568 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
569 comment about ac_cpp_err; it was incorrect, and anyway
570 ac_cpp_err is being removed below.
571 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
572 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
573 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
574 nobody uses it.
575 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
576 with werror_flag and conftest.err and so forth. This is more
577 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
578 and anyway the user shouldn't normally want to see this gorp logged.
579 Problem reported by Ralf Wildenhues.
580 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
581 empty, not 'no', since the rest of the code uses 'test -z'.
583 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
585 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
586 Use a single call to AC_DO_TOKENS rather than multiple, for
587 efficiency.
588 (_AC_LINK_IFELSE): Test that resulting file is executable.
589 Problem reported by mwoehlke in
590 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
592 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
593 than creating a file to use with test -x; this is much faster.
595 2006-10-02 Bruno Haible <bruno@clisp.org>
597 * lib/autom4te.in (Automake-preselections): Add
598 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
600 2006-09-27 Stepan Kasal <kasal@ucw.cz>
602 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
603 standard error, `experr' should be used, not `expout'.
605 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
607 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
608 fseeko testing program twice; just use the earlier result.
609 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
610 Set cache var to 'unknown' (not 'no') if leaving the macro unset
611 still doesn't let the program compile.
612 (AC_SYS_LARGEFILE): Test for _LARGE_FILES only if earlier tests
613 failed.
615 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
616 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
617 include it, without including anything else.
618 (AC_FUNC_FSEEKO): Avoid gcc -Wall warnings about constant
619 expressions.
620 (AC_FUNC_STRNLEN): Require AC_USE_SYSTEM_EXTENSIONS.
622 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
624 * lib/autoconf/functions.m4 (AC_FUNC_ERROR_AT_LINE): Check for
625 `error.h', and include it, for a `error_at_line' prototype.
626 Use a nonempty format string in the link test.
627 * lib/autoconf/functions.m4 (AC_FUNC_WAIT3): Include <sys/wait.h>,
628 for a declaration of wait3.
630 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
632 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
633 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
634 can apply to constants too, and that it checks for macro defns.
635 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,
636 and simply cast the identifier to void. This handles structure
637 values. Problem reported by Ralf Wildenhues.
638 * tests/semantics.at (AC_CHECK_DECLS): Also check enums.
640 2006-09-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

693 * bin/Makefile.am (edit): Substitute M4_DEBUGFILE.
694 * bin/autom4te.in (handle_m4): Favor --debugfile over misnamed
695 --error-output, to avoid warnings with M4 2.0.
697 2006-09-19 Stepan Kasal <kasal@ucw.cz>
699 * lib/autoconf/libs.m4 (AH_CHECK_LIB): Fix quoting, to be
700 consistent with _AH_CHECK_FUNCS and _AH_CHECK_HEADERS.
701 * lib/autoconf/headers.m4 (AH_CHECK_HEADERS_DIRENT): Likewise.
703 2006-09-15 Stepan Kasal <kasal@ucw.cz>

712 the path at runtime.
714 2006-09-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
716 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Quote the

721 * doc/autoconf.texi (Setting Output Variables): Fix example to
722 not show `--silent' being passed to a `configure' re-run.
724 2006-09-12 Paul Eggert <eggert@cs.ucla.edu>
726 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
727 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check
728 for the existence of the directory at configure-time. That's
729 too late, anyway. Problem reported by Stefan Seefeld.
731 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
732 7.1.4 /usr/bin/posix/sh described by Tim Rice in
733 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
735 2006-09-11 Stepan Kasal <kasal@ucw.cz>
737 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
738 works with GNU M4 1.4.3 again; make the normalized form
739 match the current m4 message; fix the description.
740 * test/tools.at (autom4te cache): Adapt to the change.

745 to catch glibc bug 2821

748 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
749 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
750 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
751 assume C89.
753 2006-09-08 Stepan Kasal <kasal@ucw.cz>
755 * lib/autom4te.in (Autoconf-without-aclocal-m4): Move the

773 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over

777 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug
778 from last patch.

846 * doc/autoconf.texi (Particular Programs): YYTEXT_POINTER is
847 for the default, which the user can override.
848 * lib/autoconf/programs.m4 (AC_PROG_LEX): Let _AC_PROG_LEX_YYTEXT_DECL
849 deal with LEXLIB.
850 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
851 didn't work if some values were cached but not others. Test for
852 broken lex libraries like native ia64-hp-hpux11.22; see
853 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
854 work around the problem by preferring an empty LEXLIB to -lfl or
855 -ll. Let the user set LEXLIB='' to indicate no library needed.
857 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
858 * README: Likewise.
859 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

954 * lib/autoconf/c.m4 (_AC_PROG_CC_C99): Test varargs macros and
955 64-bit preprocessor ints. Check for static initialization of
956 long long. Remove unnecessary casts.
958 2006-08-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
960 * doc/autoconf.texi (Particular Programs): Mention that
961 @INSTALL@ and @MKDIR_P@ may vary for different output files.
962 Reported by Alexandre Duret-Lutz.
964 2006-08-24 Paul Eggert <eggert@cs.ucla.edu>
966 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Also ignore
967 -lgcc?* and -lSystem, for Darwin/MacOS X. Problem reported by
968 Bill Northcott in
969 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00083.html>.
971 2006-08-22 Paul Eggert <eggert@cs.ucla.edu>
973 * lib/autoconf/c.m4 (AC_C_CONST): Don't used shadowed vars, to
974 pacify insanely picky compilers. Problem reported by Eric Blake.
976 * doc/autoconf.texi (Posix Variants): INTERACTIVE Unix is no
977 longer supported by Sun.
979 2006-08-15 Paul Eggert <eggert@cs.ucla.edu>
981 * NEWS: Autoconf now uses constructs like "#ifdef HAVE_STDLIB_H"
982 rather than "#if HAVE_STDLIB_H", so that it now works with "gcc
983 -Wundef -Werror". Problem reported by David Fang in
984 <http://lists.gnu.org/archive/html/autoconf/2006-08/msg00045.html>.
985 * doc/autoconf.texi (Header Templates, Default Includes):

1000 * lib/autoconf/headers.m4 (AC_HEADER_STAT): Don't assume that
1001 S_ISDIR etc. are valid for use in #if; POSIX doesn't guarantee
1002 this.
1004 2006-08-14 Paul Eggert <eggert@cs.ucla.edu>
1006 * doc/autoconf.texi (Limitations of Usual Tools): Document sed
1007 problems with arg script text that doesn't end in newline, and
1008 with '-e a...'. Problems reported by Ralf Wildenhues.
1010 2006-08-12 Alexandre Julliard <julliard@winehq.org> (tiny change)
1012 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1013 check for libXt by a check for libX11.
1015 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1017 * doc/autoconf.texi (config.status Invocation): Adjust according
1018 to last change.
1020 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1022 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1023 --help' should mention that `--version' outputs configuration
1024 settings. Report by Bruno Haible.
1026 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1028 Fix test suite failures reported by Pierre in
1029 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1030 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1031 the compiler created a file "b.out" when it didn't create anything
1032 at all.
1033 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1034 Discard stderr too, when invoking the test script.
1036 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
1038 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
1039 in the restoring of the werror flag.
1041 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1043 * doc/autoconf.texi (Volatile Objects): Be even a little
1044 less skeptical about "volatile", after discussion with
1045 Bruno Haible on bug-gnulib.
1046 (Limitations of Usual Tools): Warn about sed stripping
1047 leading white space from text. From Bruno Haible.
1049 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1051 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1052 compiler complains about it, even if things works after the
1053 complaint. Problem reported by Peter O'Gorman.
1055 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1056 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1057 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1059 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1061 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1062 after -R regardless of host. Patrick Welche reports that this
1063 fixes things on NetBSD 3.99.

1071 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1073 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1074 under AC_C_VOLATILE.
1075 (Volatile Objects): Be a little less skeptical about what
1076 "volatile" means. Derived from thoughts by Ben Pfaff in
1077 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1079 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1081 * doc/autoconf.texi: Fix some typos.
1083 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1085 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1086 more globally, since the 2006-06-30 patch didn't suffice. Problem
1087 reported by Keith Marshall. Also, don't bother with builddir2,
1088 since it shouldn't be needed any more.
1090 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1092 * doc/autoconf.texi (Generic compiler characteristics):
1093 Document AC_COMPUTE_INT. Fix wrong statements on Default
1094 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1096 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1097 (_AC_COMPUTE_INT): Add obsoletion warnings.
1098 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
1099 AC_COMPUTE_INT.
1101 * NEWS: Document change.
1103 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1105 * doc/autoconf.texi (Volatile Objects): New section.
1107 * NEWS: Document previous change.
1109 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1111 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1112 Require that long long int be at least 64 bits wide. C99 requires
1113 this and enough programs depend on it so we should check for it.
1114 Bruno Haible reports in
1115 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1116 that long long int is 32 bits wide with some nonstandard compilers.
1117 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1119 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1121 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1122 to a nonexistent file, so that we don't have to worry about
1123 a local site configuration that doesn't use /usr/local.
1124 Problem reported by Keith Marshall in
1125 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1127 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1129 * doc/autoconf.texi: Be more consistent about using @acronym with
1130 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1131 quite right (it talked about "OSF/Tru64", even though the
1132 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1133 and it even mentioned "OSF 4"!) and at this point there's little
1134 reason to talk about OSF any more, since it died in 1994.
1135 (Specific Compiler Characteristics): Simplify example of
1136 negative-size array.
1137 (File Descriptors): Reorder to make the text flow better.
1138 Remove joke about "appreciate the various levels"; I didn't get it.
1139 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1140 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1141 (File Descriptors, Limitations of Usual Tools):
1142 Tone down the advice against renaming or removing open files.
1143 (Limitations of Usual Tools): Add a new section, on 'rm'.
1145 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1147 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1148 -lXt in LIBS, idea from Karsten Hopp; this was due since
1149 this change:
1151 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1152 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1153 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1154 (which belong to Xt, not X itself). See Debian bug 327655.
1156 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1158 * configure.ac (AC_INIT): Bump to 2.60a.
1159 * NEWS: Update.
1161 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1163 Version 2.60.
1165 * configure.ac, NEWS: Update.
1167 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1169 * config/texinfo.tex: Sync from upstream.
1171 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1172 quadrigraph correctly in traces.
1174 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1175 Fix typos.
1177 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1178 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1179 not defined.
1180 * doc/autoconf.texi (Changed Directory Variables): New node,
1181 to document the whole `datarootdir' business a bit better.
1182 * NEWS: Update.
1183 * tests/torture.at (datarootdir workaround): Extend test.
1184 Prompted by report by Alexandre Julliard.
1186 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1188 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1189 when using default mode of IBM C 6 for AIX. Problem and two-line
1190 fix reported by Larry Jones.
1192 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1194 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1195 about literal '${datarootdir}' if a definition is found in the
1196 output file.
1198 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1200 * NEWS: Use "M4" rather than "m4" when appropriate.
1201 Problem reported by Eric Blake.
1202 * doc/autoconf.texi: Likewise.
1203 Use @acronym around BSD, GCC, and GNU when appropriate.
1204 (Why GNU M4): Renamed from "Why GNU m4".
1205 (Redefined M4 Macros): Mention that Posix
1206 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1207 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1208 to int.
1210 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1212 * bin/autom4te.in (handle_output): Do not forbid the empty
1213 pattern.
1214 * tests/tools.at (autoconf: the empty token): New test.
1216 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1218 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1219 calls, so that we do not care whether they are LIFO or FIFO;
1220 in the m4_wrap, do not check which diversion is the topmost
1221 one, just check that the stack is balanced at the end.
1222 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1223 base diversion forever--pop the previous diversion before
1224 opening the new one; consequently, remove the m4_wrap call.
1225 * lib/autotest/general.m4 (AT_INIT): Likewise.
1226 * tests/m4sugar.at: Do not use
1227 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1229 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1230 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1232 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1233 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1234 Rework example of m4wrap token-pasting trouble so that it doesn't
1235 care whether it's LIFO or FIFO.
1236 Fix some "contrary to"s that are awkward in English.
1238 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1240 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1241 to `yes' instead of `int$1_t' if the type is found, for more
1242 consistent configure output (where $1 is the number of bits).
1243 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1244 Suggested by Bruno Haible.
1246 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1247 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1248 with system headers. Report by Bruno Haible.
1250 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1252 * config/config.guess, config/config.sub: Sync from upstream.
1254 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1255 in order to avoid picking up an older installed frozen m4sh.m4f.
1256 Besides an outdated shell startup, this could have been created
1257 by an earlier M4 version with incompatible frozen file format.
1259 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1261 * README: Recommend m4 1.4.4 instead of 1.4.3..
1262 * doc/autoconf.texi: Likewise.
1263 (Special Chars in Names): Say that $(.FOO) is portable, as
1264 suggested by Stepan Kasal.
1265 (Installation Directory Variables, Build Directories):
1266 (Automatic Remaking, Subdirectories, Fortran Compiler):
1267 (Making testsuite Scripts, Defining Directories):
1268 Quote variable usages better.
1269 (Making testsuite Scripts): Add clean-local rule to makefile
1270 snippet, by Eric Blake.
1271 (Installation Directory Variables): Fix table item font.
1272 Reword slightly to clarify. Generalize advice about
1273 not using special characters to include all file-related
1274 vars, not just VPATH.
1275 (Special Chars in Variables): Warn about special characters in
1276 $(srcdir) too.
1277 (Assignments): Clarify default-value example as suggested by
1278 Ralf Wildenhues in
1279 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1280 (Special Shell Variables): Note leading ./ or ../, as suggested
1281 by Eric Blake.
1282 (Limitations of Builtins): Under cd, warn about CDPATH.
1283 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1284 Ralf Wildenhues.
1286 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1288 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1289 `@var', for texi2html.
1290 (Systemology): Some more word wrapping, for DVI output.
1291 (autom4te Invocation): The short option for `--melt' is `-M',
1292 not `-m'.
1294 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1296 * doc/autoconf.texi: More formatting and English tweaks,
1297 many suggested by Ralf Wildenhues.
1298 Reword to avoid "@code{...}'s" and the like, since it's ugly
1299 with Emacs info mode. discontents -> woes.
1300 Put a few "will"s back. time stamp -> timestamp.
1301 side-effect -> side effect.
1303 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1305 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1306 Warn about $@ not persisting. Problem reported by Julien Danjou in
1307 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1308 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1309 Mention other special chars, too.
1311 2006-06-14 Eric Blake <ebb9@byu.net>
1313 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1315 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1317 * doc/autoconf.texi: Some systematic minor improvements, as
1318 follows. Use "makefile" when talking about makefiles
1319 generally (which might be named "makefile" or "Makefile" or even
1320 "foo.mk"), "Makefile" when talking about a specific makefile
1321 called "Makefile". This unclutters the text from weird quotes
1322 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1323 values" rather than "@var{foo}s" and similar constructs containing
1324 "}s". Use "Make rules" rather than "Makefile rules". Minor
1325 English-language improvements. Change the prefix "sub-" to "sub"
1326 and "re-" to "re".
1327 Put blank lines around examples more consistently.
1328 Avoid "rather" and "very" as intensifiers.
1329 Avoid "will" as an auxiliary.
1330 (Limitations of Make): Split this node into....
1331 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1332 (Leading _ in Macro Names, Backslash-Newline-Newline):
1333 (Backslash-Newline Comments, Long Lines in Makefiles):
1334 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1335 (obj/ and Make, make -k Status, VPATH and Make):
1336 (VPATH and Double-colon, $< in Explicit Rules):
1337 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1338 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1339 New nodes, resulting from splitup of Limitations of Make.
1340 All cross-references changed. Raise the top node from
1341 a section to a chapter, and all subnodes accordingly.
1342 Redo the introductory wording to match the new organization.
1343 (Installation Directory Variables): Use an example that is
1344 closer to what Autoconf actually does. Mention that VPATH's
1345 value should not contain metacharacters or white space.
1346 (Fortran Compiler): Fix a VPATH bug in an example.
1347 (Leading _ in Macro Names): Mention that this problem is no longer
1348 of practical concern.
1349 (VPATH and Make): Reword the advice to make it clearer
1350 that Autoconf and Automake support VPATH in non-GNU make, but
1351 many packages have bugs in this area.
1352 ($< in Explicit Rules): Refer to Build Directories rather
1353 than using a (non-VPATH-safe) example.
1354 (Automatic Rule Rewriting): Mention the sort of disaster that
1355 can ensue with Solaris-style rule rewriting with VPATH.
1357 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1359 * doc/install.texi (Compilers and Options): Weaken the
1360 suggestion to use GNU make for VPATH builds.
1362 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1363 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1365 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1366 in regular expression.
1368 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1370 * doc/autoconf.texi (Installation Directory Variables):
1371 Drop extra @samp from `@table @samp' item.
1372 (Limitations of Usual Tools): Comment fix.
1373 Do not nest @samp just to point to other table items.
1374 (Writing testsuite.at) <AT_CHECK>: The second argument to
1375 `@dvar' is already @samp'ed.
1376 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1377 do not use @var in the second argument.
1379 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1381 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1382 $as_shell.exe too. Problem reported by Andreas Buening in
1383 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1385 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1387 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1388 `unused variable' compiler warning, for `-Wall -Werror'.
1389 Reported by Jaap Haitsma in
1390 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1392 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1394 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1395 case the compiler dumps core. Problem reported for
1396 OpenServer 5.0.7 by Tim Rice in
1397 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1398 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1399 Likewise.
1401 2006-06-06 Tim Rice <tim@multitalents.net>.
1403 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1404 "ERROR" only shows up in "make check" output if there is an
1405 error.
1407 2006-06-06 Eric Blake <ebb9@byu.net>
1409 * tests/tools.at (automatically allowed tokens): Fix typo.
1411 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1413 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1415 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1416 typically overflows on x86 CPUs, even though the C standard
1417 requires otherwise.
1419 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1421 * configure.ac (AC_INIT): Bump to 2.59e.
1422 * NEWS: Update.
1424 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1426 Version 2.59d.
1428 * config/texinfo.tex: Sync from upstream.
1430 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1431 seen, invoke libtoolize with `--ltdl' argument.
1432 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1433 * NEWS: Update.
1434 Suggested by Eric Blake.
1436 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1438 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1439 reported by Ralf Wildenhues.
1440 * doc/autoconf.texi (AC_FUNC_STRNLEN): Likewise.
1442 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1444 * THANKS: Update.
1446 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1448 * doc/autoconf.texi: Modernize some of the references to Solaris.
1450 2006-06-05 Stepan Kasal <kasal@ucw.cz>
1452 * lib/m4sugar/m4sugar.m4 (m4_require): Modify the error
1453 message issued by AC_REQUIRE.
1454 * tests/m4sugar.at: Check m4_require's error message.
1455 * tests/base.at: Check AC_REQUIRE's error message.
1456 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1457 to...
1458 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1459 AT_CHECK_M4.
1460 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1461 `expout' as the last parameter.
1462 * tests/tools.at: Adapt to the above change.
1464 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1466 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1467 information about race-free implementations of mkdir.

1471 * bin/autoreconf.in (help): Document M4 environment variable.
1472 * bin/autoconf.as (Usage): Likewise.
1473 * bin/autom4te.in (help): Likewise.
1474 * doc/autoconf.texi (autom4te Invocation): Likewise.
1476 2006-06-04 Paul Eggert <eggert@cs.ucla.edu>
1478 * NEWS: GNU make now recommended for VPATH builds.
1479 Mention that some macros are now documented to be obsolescent.
1480 * doc/autoconf.texi:
1481 Prefer "current" to "modern" to describe
1482 currently-used (albeit perhaps old-fashioned) hosts.
1483 Mention which ancient features no longer need to be worried about.
1484 setgid -> set-group-ID
1485 setuid -> set-user-ID (these are the Posix terms)
1486 Fix some misuses of "only".
1487 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1488 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1489 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1490 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1491 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1492 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1493 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1494 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1495 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1496 Mention that these macros are obsolescent.
1497 (Installation Directory Variables): shall -> should
1498 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1499 Mention that it's now safe to use 3 and 4.
1500 (Limitations of Usual Tools): cp -r is now specified by Posix.
1501 Omit longwinded and obsolescent discussion of cp -f.
1502 Modernize discussion of expr, ls.
1503 (Limitations of Make): Modernize discussion of VPATH builds.
1504 Mention $? as a workaround in some cases.
1505 * doc/install.texi (Basic Installation):
1506 Mention "./configure; make; make install" first. Be more
1507 specific about why this file is generic. Remove unnecessary
1508 parens. Remove misleading "only". Remove obsolete advice
1509 about csh. Don't say "configure" takes awhile; say it
1510 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1511 and CC=c99 rather than CC=c89, as these are blessed by current
1512 Posix. Recommend GNU make if doing a VPATH build.
1514 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1516 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1517 examples involving shell prompts.
1519 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1520 and Paul Eggert <eggert@cs.ucla.edu>
1522 * doc/autoconf.texi (Here-Documents): Add details about the
1523 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1524 use "here-documents" instead of "here documents".
1526 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1528 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1530 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1532 * doc/autoconf.texi (File System Conventions): Warn about ":"
1533 anywhere in directory names.
1535 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1537 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1538 about quoting the case statement, just in case.
1539 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1540 was fixed in ksh93g; reported by Ralf Wildenhues.
1542 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1544 * doc/autoconf.texi (System Services): Do not document
1545 overriding EXEEXT via ac_cv_exeext=ext.
1546 (Particular Programs) <AC_PROG_MKDIR_P>:
1547 Document that ${MKDIR_P} understands --.
1548 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1549 comment.
1551 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1553 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1554 argument with leading hyphen. Problem reported by Paul Eggert.
1556 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1558 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1559 about quoting ac_try: quote all of it, if any of it seems suspicious.
1560 This means we don't have to worry about ${ or sed any more.
1561 Also, double-quote the case statement, to work around misuses via
1562 underquoting as reported by Ralf Wildenhues in
1563 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1564 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1565 undocumented and dangerous macro.
1566 Problem reported by Ralf Wildenhues in
1567 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1569 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1571 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1572 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1573 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1575 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1577 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1578 since evidently some packages rely on the old, broken behavior.
1579 Problem reported by Ralf Wildenhues in
1580 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1581 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1582 pre-2006-05-26 definitions, but leave in the comments that
1583 these macros are dangerous and should not be used.
1584 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1585 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1586 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1587 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1588 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1590 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1592 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1593 the use of 'tr', since this is our only use of 'tr'.
1595 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1596 and Paul Eggert <eggert@cs.ucla.edu>
1598 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1599 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1601 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1603 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1604 the output file in the `${datarootdir}' test.
1606 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1607 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1609 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1610 mention of `datarootdir' in the input file(s), but literal
1611 `${datarootdir}' in the output file, and we haven't warned yet,
1612 then warn as well: the user may have (erroneously) used
1613 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1614 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1615 * tests/torture.at (datarootdir workaround): Extend this test.
1616 * NEWS: Update.
1618 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1619 and Paul Eggert <eggert@cs.ucla.edu>
1621 * doc/autoconf.texi (autoheader Invocation): The first argument to
1622 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1623 alternatives and clear up the language a bit.
1625 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1627 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1628 ac_config_guess, ac_config_sub, ac_configure.
1629 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1630 Fix typo that prevented an unnecessary space from being removed.
1631 Problems reported by Ralf Wildenhues in:
1632 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1634 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1636 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1637 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
1638 Don't use the term "thread-safe" to talk about mkdir race
1639 conditions, since the problem is more a process than a thread
1640 issue. Problem reported by Stepan Kasal in:
1641 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
1642 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
1643 the test for 'install' more closely. Look at MKDIR_P first.
1644 Look in the PATH, and at /opt/sfw/bin.
1645 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
1646 Don't bother to try mkdir -p, since we already check mkdir --version;
1647 just look at the version number. (There's no easy way to check
1648 for race-free implementations.)
1649 * tests/tools.at (autoconf: subdirectories): Adjust to above
1650 changes, since MKDIR_P now might end in "/mkdir -p".
1652 * doc/autoconf.texi (autoheader Invocation): Mention that the
1653 first arg of AC_DEFINE_UNQUOTED must be a literal.
1654 Problem reported by Ben Pfaff in
1655 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
1657 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
1658 * doc/autoconf.texi (Special Chars in Variables): New section.
1659 (Preset Output Variables): Warn about special chars in CPPFLAGS.
1660 (Installation Directory Variables): Quote $(datadir) better.
1661 (Limitations of Builtins): Describe some of eval's trickiness.
1663 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
1664 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
1665 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
1666 in front of every arg, not just trailing args. Quote apostrophes.
1667 (_AC_EVAL_ECHO): New macro.
1668 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
1669 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
1670 removed.
1671 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
1672 exposed by quoting of eval argument. Put the command on line line
1673 so it logs better.
1674 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
1675 (_AC_PATH_X, AC_PATH_X): Quote more safely.
1676 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
1677 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
1678 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
1679 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
1680 Use eval more safely.
1681 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
1682 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
1683 to be replaced.
1684 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
1685 lines, exposed by quoting of eval argument.
1687 2006-05-26 Stepan Kasal <kasal@ucw.cz>
1688 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1690 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
1691 initialization of `ac_cv_exeext', do not override it if it was
1692 already set, unless it was set to `no', for compatibility with
1693 Autoconf-2.13, and comment this.
1694 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
1695 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
1696 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
1697 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
1698 Document that this test may be overridden by setting
1699 `ac_cv_exeext'.
1701 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1703 Revert these two patches:
1705 2006-04-06 Eric Blake <ebb9@byu.net>
1706 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
1707 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
1708 2006-04-01.
1710 2006-04-01 Stepan Kasal <kasal@ucw.cz>
1711 Clean up _AC_COMPILER_EXEEXT* macros.
1712 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
1713 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
1714 ac_file to the name of the default output file and call
1715 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
1716 initial `rm' of the candidate files...
1717 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
1718 the same list in subsequent `rm' calls, and for the temporary
1719 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
1720 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
1721 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
1722 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
1723 no longer needed) by libtool. Make it a cache check.
1724 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
1725 copied here by mistake.
1726 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
1727 _AC_COMPILER_EXEEXT.
1728 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
1729 _AC_COMPILER_OBJEXT directly.
1730 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
1732 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1734 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
1735 Fix description of how the buggy `sed' works.
1737 2006-05-25 Noah Misch <noah@cs.caltech.edu>
1739 Sync from Automake:
1741 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
1742 ENOLCK. Only mention `make -j' when applicable. Only raise
1743 fatal errors when `make -j' is involved. Improve error message.
1745 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1747 * doc/autoconf.texi (Here-Documents): We now know more about
1748 the variable expansion in here documents bug.
1749 Thanks to Tim Rice and Stepan Kasal.
1751 * doc/autoconf.texi (Making testsuite Scripts): Add an example
1752 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
1754 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1756 * tests/autotest.at (Multiline command from M4 expansion):
1757 No failure to be expected if the shell quotes newlines in
1758 commands in the `set -x' output. Report by Tim Rice.
1759 * THANKS: Update.
1761 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1763 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
1764 expansion in the here-documents used by config.status, as that
1765 runs afoul of the Korn shell version M-12/28/93d bug described in
1766 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
1767 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
1768 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
1770 2006-05-23 Jim Meyering <jim@meyering.net>
1772 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
1773 Fix typo introduced with 2006-04-02 change. It reversed the sense
1774 of the test.
1776 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
1778 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
1779 ac_dB slightly, to save bytes in the script.
1780 Max out at 50 lines, rather than 96; this is more likely
1781 (though not guaranteed) to avoid obscure 'sed' failures.
1783 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1785 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
1786 `tr -d -' as bad option argument. Work around this by deleting
1787 an unrelated character.
1788 Report by Tim Rice <tim@multitalents.net>.
1790 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
1791 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1792 Stepan Kasal <kasal@ucw.cz>
1794 * doc/autoconf.texi (Particular Programs): Do not promise that
1795 we always prefer the GNU version of the program, and that we
1796 search according to PATH; both rules can have exceptions.
1797 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
1798 AC_PROG_SED. Move descriptions of limitations
1799 to the Limitations of Usual Tools section.
1800 (Limitations of Usual Tools) <sed>: Mention script length
1801 limitations with Solaris /usr/ucb/sed.
1802 <grep>: Fix wording for empty alternative. Mention that -c and
1803 -l should not be combined, and that -E and -F should not be
1804 combined.
1806 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1807 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1809 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
1810 limits in Solaris 8 /usr/ucb/sed by testing a long script.
1812 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1814 * doc/autoconf.texi (Defining Symbols): Literal parameter of
1815 AC_DEFINE is now passed to m4_pattern_allow.
1816 * NEWS: Mention that; likewise for AC_SUBST.
1817 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
1818 the parameter to m4_pattern_allow.
1819 * tests/tools.at: Add a check for that.
1821 2006-05-22 Stepan Kasal <kasal@ucw.cz>
1823 * lib/autoconf/status.m4: Fix typos.
1825 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1827 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
1828 only the files that this macro generates.
1830 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1832 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
1833 the HP-UX sed limitation of 99 commands, labels do not count.
1834 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
1835 in the comment.
1836 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
1838 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
1840 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
1841 Import the following fix from coreutils:
1843 2006-01-13 Jim Meyering <jim@meyering.net>
1845 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
1846 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
1847 not double-quote uses of that variable, to accommodate the rare
1848 case in which getmntent is available in none of the libraries
1849 checked. This happens at least on FreeBSD 5.0.
1851 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
1853 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
1854 ac_config_guess, ac_config_sub, and ac_configure, since evidently
1855 some other programs unwisely rely on these undocumented vars.
1856 But put in warning comments about them.
1857 Problem reported by Ralf Wildenhues in
1858 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
1859 * NEWS: Document that these variables are intended to go away.
1861 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1863 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
1864 and set the language to C++ (analogous to the equivalent Fortran
1865 tests).
1867 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
1868 * doc/autoconf.texi (C++ Compiler): Document it.
1869 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
1870 * NEWS: Update.
1872 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
1874 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
1875 that caused config.status to generate 100-command sed scripts; the
1876 portable limit is 99.
1878 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1880 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
1881 variable `ac_d' instead of `d' to avoid infringing namespace.
1882 Report by Ralf Menzel.
1884 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
1886 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
1887 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
1888 * tests/tools.at (autoconf: subdirectories): New test, taken from
1889 the corresponding problem report by Ralf Wildenhues in:
1890 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
1892 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
1893 Quote some uses of shell variables if they might suffer unexpected
1894 globbing. This doesn't fix all instances of quoting problems that
1895 I found, just the easy ones that look safe.
1896 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
1897 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
1898 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
1899 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
1900 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
1901 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

1905 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
1907 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1909 * bin/autoreconf.in ($help): Reword according to the manual.
1910 Suggested by Olly Betts.
1912 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
1913 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1915 * bin/autoreconf.in: Pass the directory argument to
1916 `require_configure_ac'. Fix comment.
1917 * tests/torture.at (Configuring subdirectories): Expose this.
1918 Reported by Olly Betts.
1920 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1922 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
1923 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
1924 Automake as follows:
1926 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
1927 `$configure_in' instead of `configure.in', to preserve
1928 directory component.
1930 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1932 * config/config.guess, config/config.sub, config/texinfo.tex,
1933 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
1935 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
1937 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
1938 test for C99 conformance; (bool) 0.5 is an integer constant
1939 expression, but (bool) -0.5 is not. Problem reported by Fedor
1940 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
1942 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
1944 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
1945 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
1946 Warn about obsolete install-sh files. Remove stray sentence
1947 fragment and fix cross reference.
1948 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
1949 install -d; this undoes the 2006-05-10 change.
1950 (MKDIR_P): Mark with AN_MAKEVAR.
1951 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
1952 that we don't require $INSTALL to be thread-safe. Move comments
1953 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
1954 of AC_PROG_INSTALL. Output a message saying that we're checking
1955 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
1956 MKDIR_P instead of AC_SUBST.
1957 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
1958 Special magic for MKDIR_P, too.
1959 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
1960 a dnl.
1961 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
1963 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
1965 Sync from Automake, as follows:
1967 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1968 * config/install-sh: Initialize IFS, so field splitting isn't
1969 turned off later.
1970 * config/mkinstalldirs: Likewise.
1971 * config/missing: Remove superfluous quotes. Replace all uses of
1972 `[' by `test', for consistency, and for..
1973 * config/missing (sed_minuso, sed_output): New variables.
1974 (autom4te, help2man, makeinfo): Use them. Unifies detection of
1975 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
1976 Fixes `missing' to detect `--output' for help2man. Fixes
1977 PR automake/483. Report by Dennis J. Linse.
1978 (autom4te): Document in `missing --help'.
1980 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
1982 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
1983 * config/install-sh: Don't use 'path' to talk about file names,
1984 as per GNU coding standards. Close a race condition reported by Ralf
1985 Wildenhues and Stepan Kasal. There is still a race condition
1986 on hosts that predate Posix 1003.1-1992, but we can't help this.
1987 Don't mishandle weird characters like space on pre-Posix hosts.
1988 Invoke mkdir at most once per dir arg on pre-Posix hosts.
1989 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
1990 AC_PROG_MKDIR_P from AS_MKDIR_P.
1991 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
1992 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
1993 earlier editions are not (including Automake 1.8.3).
1994 Do not suggest mkinstalldirs for thread-safety.
1995 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
1996 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
1997 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
1998 presence of special characters and race conditions.
1999 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2000 in Autoconf's name space.
2002 2006-05-10 Bruno Haible <bruno@clisp.org>
2003 and Paul Eggert <eggert@cs.ucla.edu>
2005 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2006 from Automake with minor changes.
2007 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2009 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2011 * config/install-sh: Update to Automake CVS version, as follows:
2012 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2013 * lib/install-sh: Simplify the expr implementation of dirname.
2014 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2015 * lib/install-sh: Handle --, and diagnose unknown options.
2017 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2019 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2020 `./autom4te' to create `./testsuite', since the `all' target
2021 will ensure its presence, but `installcheck' should not create
2022 the uninstalled wrappers.
2024 * tests/torture.at (Unusual Automake input files): Skip if we
2025 detect automake < 1.8.
2027 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2029 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2030 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2031 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2032 * NEWS: Update.
2034 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2036 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2037 munge (multiple) white space and other oddities.
2038 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2039 single quotes in variable assignment.
2040 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2041 and similar failures by adding multiple spaces, tabs, and other
2042 special characters.
2043 Report and different test suggested by Francesco Romani
2044 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2046 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2047 single quotes, we only need to search for single quotes; this
2048 both simplifies the search pattern, and makes us less
2049 susceptible to `echo' variations for arguments not containing
2050 single quotes.
2051 (_AC_ARG_VAR_VALIDATE): Likewise.
2053 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2055 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2056 `$*' and IFS concatenation issue with traditional shells and
2057 bash-2.04. Report by Seanster@Seanster.com.
2059 2006-05-03 Bruno Haible <bruno@clisp.org>
2061 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2062 precisely which Mac OS X versions have the od problem.
2064 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2066 * doc/autoconf.texi: Use @option systematically.
2068 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2069 and Bruno Haible <bruno@clisp.org>
2071 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2072 about 'od'.
2073 (Integer Overflow): Mention the special case of integer division
2074 overflow.
2076 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2078 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2079 traditional shells like the Solaris one that do not use the
2080 first IFS character for assembling `$*'.
2081 Prompted by a related report from autoconf_bug@nro.ca.
2083 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2084 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2086 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2087 Mention more problems with the -e option.
2089 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2091 * NEWS: Typo.
2092 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2094 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2095 in URLs to improve DVI formatted output (requires texinfo 4.6).
2096 (System Services, Systemology, Shellology): Likewise.
2097 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2098 output.
2100 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2101 continuous text.
2102 (Runtime): Fix macro argument names to match description:
2103 `action-if-found' -> `action-if-true' and similarly.
2104 (Obsolete Macros): Likewise.
2105 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2106 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2107 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2109 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2111 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2113 * ChangeLog: Typo.
2114 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2115 DVI output.

2122 * tests/local.at: Likewise.
2124 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2126 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2127 (Integer Overflow, Null Pointers, Buffer Overruns):
2128 (Floating Point Portability, Exiting Portably): New sections.
2129 (Writing Test Programs): Fix some langauge. Recommend exiting
2130 with status 1, not merely nonzero. Clarify exit declaration.
2131 (Run Time): Move C exit status stuff to new Exiting Portably section.
2132 (Systemology): Mention Posix and levenez. Update v7 reference.
2133 (Portable Shell): Mention the Posix shell.
2135 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2137 * bin/autoconf.as (me): Replace by as_me.
2139 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2141 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2142 since as_me isn't set yet.
2144 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2146 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2147 a few minor bugs in this area.
2149 * doc/autoconf.texi (Programming in M4sh): Comment out the
2150 documentation of AS_BASENAME, for now.
2151 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2152 (Limitations of Builtins) <basename>: Do not refer to
2153 AS_BASENAME.
2154 * bin/autoconf.as (me): Don't use AS_BASENAME.
2155 (dir): Remove the unused variable.
2156 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2157 AS_DETECT_REQUIRED. All uses changed.

2159 All uses changed.
2160 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.

2163 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2164 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2165 (_AS_DIRNAME_PREPARE): Likewise.
2166 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2167 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.

2180 with more accuracy and detail.
2182 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2184 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2185 Archive is not officially `GNU' any more. Update URL.
2186 (Defining Directories): Likewise
2187 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2189 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2191 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2192 newline from the `trap' code to finish `config.log'; the NetBSD
2193 /bin/sh resets the exit status after an empty command, as
2194 documented in doc/autoconf.texi.
2195 Reported by Dalibor Topic <robilad@kaffe.org>.
2197 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2199 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2200 Suggested by Bruno Haible.
2202 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2204 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2205 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2206 Instead, just list the shells that we know work.
2207 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2208 changed. Be more cautious about the _cv_ variable.
2209 * tests/tools.at (Syntax of the shell scripts): Check the
2210 _cv_ variable once, at first, to avoid an internal autoconf error
2211 when sh -n does not work.
2213 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2215 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2217 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2219 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2220 use ">&-" since we're only 99.999% sure that this is portable,
2221 and since the MinGW bug is fixed in a different way.
2222 * lib/autotest/general.m4 (AT_INIT): Likewise.
2224 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2226 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2227 before opening config.log, to avoid hitting a bug on MinGW.
2229 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2231 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2232 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2233 This works around a MinGW bug reported by Eric Paire.
2234 Make sure that all writes to the log file append to it,
2235 rather than possibly losing data.
2236 * lib/autotest/general.m4 (AT_INIT): Likewise.
2238 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2240 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2241 description.
2243 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2245 * NEWS: Update.
2247 * configure.ac (AC_INIT): Bump to 2.59d.
2249 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2251 Version 2.59c.
2253 * Makefile.maint (news-date-check): Do not require a leading `*'
2254 before the release date in NEWS.
2256 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2257 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2259 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2260 the instantiated file do not contain the string 'datarootdir'
2261 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2262 @mandir@, replace the reference '${datarootdir}' by the value.
2263 * tests/torture.at (datarootdir workaround): New test.
2264 * NEWS: Advertise this temporary fixup.
2265 Based on a patch by Bruno Haible, reported and analyzed by
2266 Paul Eggert and Noah Misch.
2268 2006-04-12 Eric Blake <ebb9@byu.net>
2270 * tests/autotest.at (Debugging a failed test): Fix comment.
2272 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2274 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2275 all the changes since 2006-04-07.
2277 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2279 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2280 succeeded, but `ln -s file dir' failed, take care to remove the
2281 leftover target before the next test, to prevent its spurious
2282 failure; also make sure `ln file dir' works before selecting it.
2283 Thanks to Keith Marshall for pointing this out.
2284 * THANKS: Update.
2286 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2287 assignments in `at_debug_args', so that we put them correctly
2288 in the `run' script.
2289 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2290 Reported by Eric Blake.
2292 2006-04-11 Eric Blake <ebb9@byu.net>
2294 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2295 top-level tests after micro-suite has been run. Used in...
2296 (Debugging a successful test, Debugging script and environment),
2297 (Debugging a failed test): ...these new tests. The first of these
2298 is fixed by...
2299 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2300 macro, split out from...
2301 (AT_INIT): ...here, so that using -d also generates a run script.
2302 Document that -d inhibits top-level logging.
2303 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2304 inhibits top-level logging; debug scripts are created.
2306 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2307 check.
2308 * tests/autotest.at (Empty test, Empty check): New test to check it.
2310 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2311 from gcc.
2313 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2315 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2316 the files if a problem appears. Make the empty *.at files
2317 read-only, too. Proposed by Ralf Wildenhues.
2319 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2321 * config/Makefile.am: Add comment to force updated Makefile.in.
2323 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2324 space only patch to this file, this patch causes the Makefile.in
2325 files that include freeze.mk to be updated, and thus have a
2326 newer time stamp again, which in turn makes a pristine CVS
2327 checkout have correct time stamps.
2329 * Makefile.maint (cvs-sv): New macro, to be used..
2330 (config.guess-url_prefix, config.sub-url_prefix)
2331 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2332 point to CVS text checkout of Gnulib files.
2333 (copyright-check): Bump current year.
2334 (announcement): Do not hard-wire `./announce-gen'.
2335 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2336 correctly.
2337 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2338 `chmod +x'.
2339 (wget_files): Update config.guess, config.sub, texinfo.tex by
2340 `wget-update', now that their URLs work again.
2342 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2344 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2345 Problem noted by Paul D. Smith.
2347 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2349 * doc/autoconf.texi: Remove unused words from word list.
2350 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2351 .x-sc_trailing_space: New files.
2353 * doc/standards.texi: Sync from gnulib.
2355 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2356 `LIBOBJDIR' as experimental.
2358 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2359 with a target directory; it's internally implemented as `cp'
2360 anyway, but since Autoconf advertises the possibility to use
2361 a target directory when LN_S is `ln -s', we need to find out.
2362 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2363 analyzed by Keith Marshall <keith.marshall@total.com>.
2365 * THANKS: Update.
2367 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2369 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2370 confdefs.h as-is. In general, if it has backslash-newline or the
2371 like, then it doesn't work either to sort or to remove empty
2372 lines.
2374 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2376 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2378 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2380 * lib/autom4te.in (Automake-preselections): Preselect
2381 _AM_SUBST_NOTMAKE.
2383 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2385 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2386 apostrophe within a single-quoted string, as this is the usual
2387 tradition and is easier to read than '"'"'. Don't rely on the
2388 shell treating "$/" like '$/'. Use a more-consistent indenting
2389 style for the trap.
2391 2006-04-09 Eric Blake <ebb9@byu.net>
2393 * tests/autotest.at (Backquote command substitution),
2394 (Multiline backquote command substitution): Remove mistaken
2395 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2396 applied...
2397 (Parenthetical command substitution, Multiline parenthetical
2398 command substitution): here.
2400 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

2417 (Particular Functions): Alphabetize. Add AC_FUNC_STRTOLD.
2418 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
2419 Gnulib section.
2420 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
2421 suggest a #define rather than a typedef for _Bool, and mention
2422 Gnulib rather than trying to substitute stdbool code.

2424 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
2425 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

2430 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
2431 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
2432 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
2433 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2434 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2435 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2436 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
2437 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
2438 (Coding Style). Don't mention m4_expand_once.
2439 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
2440 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
2441 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.

2449 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
2450 Catch a bug in an HP-UX C compiler.
2451 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
2452 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):

2456 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
2457 New macros.
2459 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
2460 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
2462 2006-04-08 Stepan Kasal <kasal@ucw.cz>
2464 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
2465 of the warning introduced by the 2001-08-28 change.
2467 2006-04-08 Stepan Kasal <kasal@ucw.cz>,

2473 that contains braces.
2475 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2477 Revert the patch from 2006-04-01 and only improve
2478 _AS_DETECT_BETTER_SHELL:
2480 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2481 skip nonexistent directories.
2482 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2483 only shell candidates which exist.
2484 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2485 * lib/autotest/general.m4 (AT_INIT): No need to give three
2486 parameters to _AS_PATH_WALK.
2488 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2489 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2491 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2492 distinguish m4sugar macros.
2493 * tests/tools.at (autoupdating with aclocal and m4_include):
2494 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2495 test case by Noah Misch <noah@cs.caltech.edu>.
2497 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2499 Revert my change from 2006-03-17, in other words:
2500 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2501 and DUALCASE=1.
2502 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2503 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2504 it is set.
2506 2006-04-07 Eric Blake <ebb9@byu.net>
2508 * doc/autoconf.texi (Programming in M4sh): Document that
2509 AS_MKDIR_P exits the script on failure.
2510 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2512 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2514 * config/elisp-comp, config/install-sh, config/mdate-sh,
2515 config/missing, config/mkinstalldirs: Sync from Automake.
2517 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
2518 from Automake.
2520 * doc/make-stds.texi: Sync from gnulib.

2524 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2525 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

2528 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
2529 Eric Blake <ebb9@byu.net>,
2530 Paul Eggert <eggert@cs.ucla.edu>,
2531 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2533 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2534 whether `set' quotes correctly: redirect stderr of the tested
2535 `set', and use a subshell, for Ultrix; use `sed' instead of
2536 `grep' for zsh `set' which may write binary output; match only
2537 at the beginning of a line, to avoid false positives.
2538 In order to avoid false positives by unrelated variables with
2539 multiline content, put the dump algorithm in a subshell and
2540 unset all variables containing newlines (except some which are
2541 special to the shell). Warn about cache variables that are
2542 unset.
2544 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2546 * config/config.guess, config/config.sub, config/texinfo.tex:
2547 Sync from upstream.
2549 * tests/mktests.sh: Reword comments.
2551 * tests/mktests.sh: Only skip internal macros starting with
2552 `_AC_' or `__AC_'. Noted by Stepan Kasal.

2555 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2556 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2557 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2558 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2560 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2561 shell issue with double-quoted command substitutions of native
2562 commands.
2563 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2564 Marshall.
2566 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

2572 (m4-check): Likewise.
2573 (sc_system_h_headers): Do not print rule on execution.
2574 (sc_tight_scope): Do not fail for non-existing `src' directory.
2575 (sc_changelog): Skip the Copyright footer.
2576 * lib/autoconf/lang.m4: Remove trailing space.
2578 * lib/autoconf/status.m4: More replacements to
2579 <tab><space> where this makes sense.
2581 2006-04-06 Stepan Kasal <kasal@ucw.cz>
2583 * tests/Makefile.am (maintainer-check-posix):
2584 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2586 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2587 ac_config_<foo>s again, sometimes normalized, sometimes not.
2588 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2589 (AC_CONFIG_COMMANDS): Do not do so here.
2590 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2591 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2592 2005-07-25 rewrite. Noticed by Noah Misch.
2594 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2595 _AC_PRESERVE_HELP_ORDER, ...
2596 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2598 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2599 inside m4_expand_once; it is redundant.
2601 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2602 for --help from Cygnus `configure.'
2604 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
2606 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
2607 on a patch proposed by Ralf Wildenhues.
2609 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2611 * lib/autoconf/status.m4: Replace <space>''<tab> with
2612 <tab><space> where this makes sense.
2614 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
2615 Noah Misch <noah@cs.caltech.edu>
2617 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2618 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2619 * doc/autoconf.texi (Help Formatting): New node.
2620 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2622 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2624 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
2625 lib/autoconf/specific.m4, lib/autoconf/status.m4,
2626 lib/autoconf/types.m4, lib/autotest/general.m4,
2627 tests/mktests.sh, tests/torture.at: White space cleanup:
2628 remove some SPACE before TAB, or add quoting ('' or @&t@).
2630 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
2632 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
2634 2006-04-05 Eric Blake <ebb9@byu.net>
2636 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2637 empty test suite works.
2638 * tests/autotest.at (Empty test suite): Remove xfail.
2640 2006-04-05 Noah Misch <noah@cs.caltech.edu>
2642 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Do not append normalized
2643 TAGS to ac_config_<foo>s.
2644 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
2645 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
2646 normalizing it, consistent it with previous releases.
2647 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
2649 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
2651 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
2652 Use simplified args that Eric Blake originally suggested.
2654 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
2656 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
2657 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
2658 Use 'comm' rather than N instances of grep; this also fixes a bug
2659 whereby substrings were incorrectly matched, causing us to not
2660 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
2661 (exclude_list): Exclude empty macros.
2662 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
2664 Use awk rather than grep -E or egrep, to avoid
2665 portability problems with regular expressions containing newlines.
2666 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
2667 Switch from grep to awk syntax.
2668 (ac_exclude_script): Renamed from ac_exclude_egrep.
2669 (au_exclude_script): Renamed from au_exclude_egrep.
2671 2006-04-04 Noah Misch <noah@cs.caltech.edu>
2673 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
2674 a subdirectory subject to Cygnus `configure'.
2675 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
2677 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
2678 report request when we have no AC_PACKAGE_BUGREPORT.
2680 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2682 * THANKS: Update.
2684 * tests/mktests.sh: Update copyright year in the header of the
2685 generated files.
2687 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
2688 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
2689 typedef'ed restricted pointer, to catch a compiler bug on
2690 HP-UX 11.x, and fix warnings so it passes with -Werror.
2691 (_AC_PROG_CC_C99): Likewise.
2692 Reported by Albert Chin <china@thewrittenword.com>.
2693 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.
2695 2006-04-03 Noah Misch <noah@cs.caltech.edu>
2697 * bin/autoscan.in (subdirs): New global.
2698 (scan_file): Prune directories with configure{,.{ac,in,gnu}}.
2699 (output): Emit AC_CONFIG_SUBDIRS as needed.
2700 * tests/autoscan.at (autoscan): Remove XFAIL.
2702 2006-04-03 Noah Misch <noah@cs.caltech.edu>
2704 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.

2722 Remove; all uses removed.
2723 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

2745 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2746 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2747 ac_file to the name of the default output file and call
2748 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2749 initial `rm' of the candidate files...
2750 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2751 the same list in subsequent `rm' calls, and for the temporary
2752 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2753 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2754 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2755 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2756 no longer needed) by libtool. Make it a cache check.

2833 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2835 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
2836 switch all of them on and of when necessary. Fixes the bug when
2837 m4sugar macros (e.g., m4_define) were expanded after the first
2838 automatic update (e.g., after AC_PREREQ or AC_INIT).
2840 2006-03-31 Paul Eggert <eggert@cs.ucla.edu>

3094 _AC_SUBST_FILES fragment. Separate `{' and `r' commands by
3095 newline for portability.
3096 * tests/torture.at (Torturing config.status): Also test 100

3537 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3538 comparing its address. Intel's interprocedural optimization was

3556 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3557 Stepan Kasal <kasal@ucw.cz>
3559 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3560 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3561 make its content writable before removing it. Remove an errorneous
3562 comment from the end, where the logs of the failed tests are copied
3563 to the main log file.
3565 2005-09-27 Stepan Kasal <kasal@ucw.cz>

3572 problems if the testsuite were running too fast.
3574 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>

3588 suggested by Ben Elliston. Handle weird characters correctly.
3590 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3592 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3593 calls, so that the final expansion of this macro is shorter.
3594 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3595 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3596 the cleanup there. Use AS_VAR_* macros, to be more general.
3597 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3599 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3601 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

3621 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3622 in the example. Reported by Bruno Haible.
3623 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3624 "if $undefined_var;" succeeds with my shell.

3627 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3628 but change the m4_divert_text to m4_divert_once.
3630 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
3632 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
3633 Work around bug in Solaris /usr/xpg4/bin/awk.
3634 The bug is present in at least Solaris 8 through 10.
3636 2005-08-24 Stepan Kasal <kasal@ucw.cz>
3638 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
3639 some evil values and relying on the fact that $* concatenates the
3640 parameters by the first character from IFS.
3642 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
3643 Stepan Kasal <kasal@ucw.cz>

3648 Update limitations about when to call AC_CONFIG_HEADERS.
3649 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
3650 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
3651 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
3652 ``Configuration Actions''; fix their index entries.
3654 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
3655 options correctly. Process N-M as M-N if M is smaller than N.
3656 Process ranges correctly so that N-N will run only N.
3657 Sort and uniquify the tests that will be run. If there is more
3658 than one test, reinsert the banners for the tests.
3659 * tests/autotest.at (Keywords): Unmark XFAIL.
3661 2005-08-23 Stepan Kasal <kasal@ucw.cz>

3664 before passing the macro name to AH_TEMPLATE.
3666 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
3667 now opens log after option processing; in particular, --version
3668 and --help do not touch config.log.
3670 * Makefile.maint: Revert the change from 2005-08-12.
3672 2005-08-22 Stepan Kasal <kasal@ucw.cz>

3685 Prepend to LIBS, not append, in examples.
3687 2005-08-16 Stepan Kasal <kasal@ucw.cz>
3689 When building in place, set srcdir="."; suggested by Tim Van Holder.
3691 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
3692 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
3693 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
3694 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
3695 does not mean "no --srcdir option".
3697 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3699 * tests/autoscan.at (autoscan): New file.

3711 2005-07-27 Stepan Kasal <kasal@ucw.cz>
3713 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason

3726 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
3727 "<tab>" in comment, so that the point is understandable.
3729 2005-07-25 Stepan Kasal <kasal@ucw.cz>
3731 Rewrite substantial part of lib/autoconf/status.m4.
3732 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
3733 and CONFIG_COMMANDS are not processed in four separate loops.
3734 Instead, there is one main loop. This alows that the common code
3735 is expanded only once, thus config.status (and configure) is smaller.
3737 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
3738 the AC_LIST_FILES and cousins macros are no longer used.
3740 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
3741 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
3742 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
3743 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
3744 contain the initialization, nor the for loop, nor the associated
3745 commands; all these go to ...
3746 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
3747 _AC_OUTPUT_CONFIG_STATUS.
3748 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
3749 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
3750 (_AC_OUTPUT_FILE): The creation of the sed script ...
3751 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
3752 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
3753 _AC_OUTPUT_MAIN_LOOP.
3754 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
3755 _AC_CONFIG_COMMANDS): Use ...
3756 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
3757 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
3758 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
3759 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
3760 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
3761 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
3762 ... new macros.
3763 (_AC_CONFIG_UNIQUE): Update.
3764 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
3765 Replaced by this ...
3766 (_AC_LIST_TAGS): ... new common macro.
3767 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
3768 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
3769 (_AC_LIST_TAG_COMMANDS): ... new common macro.
3770 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
3771 this didn't belong to the `config commands' section.
3772 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
3773 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
3774 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
3775 to the `config commands' section either.
3776 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
3777 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
3779 ... and many changes to the comments nearby.
3781 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
3782 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
3783 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
3784 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
3785 (#define header templates): The comment at the top of the generated
3786 header now includes the name(s) of the source file(s).
3788 Several unrelated small changes:
3790 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
3791 parameter to AC_DIAGNOSE.
3792 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
3793 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
3794 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
3795 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
3796 with AU::AC_OUTPUT.
3797 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
3798 in AC_OUTPUT doesn't double-quote it either.
3799 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
3800 parameters.
3802 2005-07-10 Stepan Kasal <kasal@ucw.cz>
3804 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
3805 versions of Portland Group compiler produce single- and double-quoted
3806 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
3807 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
3809 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
3811 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3812 This is a corrected version of yesterday's patch.
3814 2005-07-07 Stepan Kasal <kasal@ucw.cz>
3816 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
3817 path, too; insert a "===" to emphasize the line.
3819 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
3820 ac_cv_build_alias to ac_build_alias.
3821 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
3823 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
3824 change eliminates it. Problem reported by Alexandre Duret-Lutz.
3825 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
3826 (AC_ARG_VAR): ... here.
3827 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
3828 target_alias.
3830 Keep a list of all precious variables and process them with one simple
3831 for loop, instead of expanding all commands, or, OTOH, complicated
3832 processing of output of "set".
3833 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
3834 variable names in new macro...
3835 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
3836 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
3837 a loop to assign all ac_env_* and ac_cv_env_* variables.
3838 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
3839 to INIT_PREPARE.
3840 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
3841 its value to shell variable ac_precious_vars and call
3842 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
3843 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
3844 _AC_ARG_VAR_VALIDATE.
3846 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
3847 and the AC_SUBSTs ...
3848 (AC_INIT): ... here.
3850 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
3851 the ac_subst_files section in config.log.
3853 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
3855 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>

3862 Fix problems reported by Nicolas Joly.
3863 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
3864 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
3865 They are generated by the Tru64 v5.1B shell.
3867 2005-07-05 Stepan Kasal <kasal@ucw.cz>
3869 Fix my changes from 2005-07-01; reported by Noah Misch.
3870 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
3871 description, the macro now accepts only a single tag.
3872 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
3874 Fix cases when the varsions of Autoconf and Autotest don't match.
3875 Reported by Noah Misch.
3876 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
3877 at_top_builddir, for compatibility with older autotest.
3878 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
3879 is not set, use at_top_builddir, for compatibility with older
3880 versions of autoconf.
3882 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
3884 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
3885 Problem reported by Patrick Welche.
3887 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
3889 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
3890 sed substitution command, so that we allow | in program prefixes
3891 and program suffixes. (& is a problem anyway; we're not fixing
3892 that here.)
3893 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
3894 configure_input, top_builddir, srcdir, etc.
3895 * lib/autotest/general.m4 (AT_INIT): Likewise, for
3896 PATH_SEPARATOR in AUTOTEST_PATH.
3898 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
3900 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
3901 for loop over config.site files using `set', to allow
3902 directory names containing IFS characters.
3904 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
3906 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
3907 directories with weird names. Apparently some people like living
3908 on the edge. However, improve the test that "pwd" actually does
3909 report a name for the working directory.
3910 * NEWS: Remove the claim that we test for funny chars in dir names.
3912 2005-07-01 Stepan Kasal <kasal@ucw.cz>

3925 (Generic Functions): Mention the Gnulib project.
3926 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
3928 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
3929 document to output the default config_* lists to config.status.
3930 Don't recognize option --file, if the functionality is not there.
3931 Likewise for --header; moreover, recognize --he and --h as shortcuts
3932 for --help in that case.
3934 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
3935 matches the order of execution. No code changed.

3957 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
3958 (AC_SUBST): Call it.
3959 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
3960 the directory specific variables; but don't call it for configure_input.
3962 2005-06-28 Derek Price <derek@ximbiot.com>
3964 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
3965 addition.
3967 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
3969 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
3970 directory have inherent problems with special characters like spaces,
3971 due to limitations in Make syntax. Problem reported by Alexandre
3972 Duret-Lutz.
3973 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
3974 Also, fix Tru64 porting problem with shell patterns,

3988 variable into diagnostic. Make the diagnostic an error, not a warning,
3989 because we really don't support spaces and suchlike in dir names.
3990 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
3991 Don't worry about backslashes in srcdir; it can't happen now.

3993 Simplify ac_optarg handling.
3994 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4002 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4004 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4005 that '\|' is not allowed in BREs; recommend using newline separated
4006 list of patterns instead of multiple -e options.
4008 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4010 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4016 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4018 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4019 b, t, r, w commands require single space, while : cannot have any.
4020 (Special Shell Variables): Fix sed code this in the example.
4021 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4022 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4024 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4025 expand to the empty list. Don't use two pairs of m4_changequote,
4026 it's not necessary.
4028 2005-06-20 Derek Price <derek@ximbiot.com>
4030 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4032 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4034 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4035 * doc/autoconf.texi:
4036 Don't mention Solaris versions so much, if a
4037 problem is common to all extant versions of Solaris. Say "SunOS
4038 4" instead of "SunOS" for SunOS 4.
4039 (awk): Mention more of the limitations of traditional Awk.
4040 (cat): Don't talk about cat -v.
4042 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
4044 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
4045 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

4047 to be compatible with glibc strverscmp.
4048 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4050 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4051 on Mac OS X 10.4 reported by Peter O'Gorman in:
4052 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
4053 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4054 Use shell builtins rather than 'expr', to work around expr bug.
4056 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4058 * doc/autoconf.texi: "filesystem" -> "file system".
4059 "behaviour" -> "behavior".
4060 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
4061 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4062 as per POSIX.
4063 * lib/m4sugar/m4sh.m4: Likewise.

4065 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
4067 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
4068 (.x.1): Ignore the time stamp in the .TH line when deciding whether
4069 to update the man page. That way, we don't have to check in new
4070 man pages every month.
4072 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4073 quotes and backslashes. Patch from Derek Price.

4078 AS_TR_SH.
4080 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4082 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4083 -u, since it outputs chatter if the input files are the same.
4084 Problem reported by Ralf Menzel.
4086 2005-06-08 Derek Price <derek@ximbiot.com>
4088 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4089 renaming them since they are about to be redefined anyhow.
4091 2005-06-08 Derek Price <derek@ximbiot.com>
4093 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4094 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4095 Move m4_undefine to alphabetical order.
4097 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4099 * README: Recommend GNU M4 1.4.3 or later.
4100 * doc/autoconf.texi (Introduction): Likewise.
4101 Reword to avoid some formatting glitches.
4102 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4103 Clarify explanation of HP compiler bug.
4104 Redo example output tp match current CVS snapshot.
4105 Use @example.org in email addresses when the examples
4106 might get inadvertently cut-and-pasted into user code.
4107 Remove example of autom4te usage that doesn't seem to work now.
4108 Use modern AC_INIT (except when the example is meant to be
4109 shown with Autoconf 2.13).
4110 Update ksh info for Solaris 9 and later.
4111 KB -> kB.
4112 Modernize description of Automake versions a bit.
4113 Don't claim a future version of Autoconf is near.
4114 * doc/install.texi: Reword to avoid some formatting glitches.
4116 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4118 * doc/autoconf.texi: Add [] to examples, so that the manual
4119 follows its own advice about quoting better.
4120 Reword to avoid some formatting glitches.
4121 * doc/installt.exi: Reword to avoid some formatting glitches.
4123 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4124 Tru64 ksh pattern matching bug. Reported against Libtool by
4125 Albert Chin <libtool@mlists.thewrittenword.com> and
4126 Nicolas Joly <njoly@pasteur.fr>.
4128 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4130 m4_cdr of one-member list was [[]] (one-member list containing an
4131 empty string) instead of [] (an empty list. Callers were skewed to
4132 match this misbehaviour. As a consequence of this:
4133 - m4_foreach([x], [], [foo]) expanded to `foo', while
4134 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4135 This bug has been fixed:
4137 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4138 expand to an empty string; print error msg if called without
4139 an argument list.
4140 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4141 misbehaviour; handle [] and [[]] correctly.
4143 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4145 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
4146 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
4147 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4149 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4151 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4152 swallow records with more than 99 fields.
4153 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4154 parse the long line.
4156 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4158 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4159 swallow literals longer than 399. Reported by Ralf Wildenhues.
4160 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4161 to workaround this limitation.
4163 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4165 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4166 to gfortran, and make these the first two compiler names
4167 checked (following the general autoconf preference for gcc).
4169 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4171 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4172 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4173 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4175 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4177 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4178 expression of unbounded size when processing the --list
4179 option. This runs afoul of a limit of 399 bytes per regular
4180 expression on AIX. Problem reported by Ralf Wildenhues.
4182 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4184 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4185 * doc/autoconf.texi (Particular Headers): Reword example
4186 for multiline stdbool replacement.
4187 (Setting Output Variables): Reword text a bit. Don't
4188 give all the details about |#_!!_#|.
4189 Reword description of line replacement.
4191 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4193 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4194 now contain newlines, and substituted files must be referenced on
4195 a line alone; the sed scripts to substitute them are now very
4196 different.
4197 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4198 commands can be put in a sed script portably.
4199 * doc/autoconf.texi (Setting Output Variables): Document above
4200 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4201 use of multiline substitution.
4202 * tests/torture.at: No longer expect substitution of newline to fail.
4204 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
4206 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
4207 From Ralf Menzel (trivial change).
4209 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
4211 * tests/local.at: Don't attempt to check for negated character
4212 classes in shell scripts. The test was too brittle.
4214 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4216 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4217 * doc/autoconf.texi (Limitations of Builtins): Document this
4218 limitation.
4220 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4222 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4223 common code; used in many places in the tree.
4224 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4225 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4227 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4229 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4230 messages when ac_unique_file is not found.
4231 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4232 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4233 commands, for consistency with AC_MSG_ERROR and such.
4235 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4237 * bin/Makefile.am: Merge the two rules for creating scripts.
4239 2005-05-23 Stepan Kasal <kasal@ucw.cz>
4241 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
4242 obsolete; it was never documented.
4243 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
4245 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4247 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4248 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4249 (ac_top_builddir): ... this ...
4250 (ac_top_build_prefix): ... to this; the old name is also kept, for
4251 backward compatibility.
4252 (ac_top_builddir_sub): New variable, without the trailing slash,
4253 always nonempty.
4254 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4255 * doc/autoconf.texi (Configuration Actions): Rename
4256 ac_top_builddir to ac_top_build_prefix.
4257 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4258 at_top_builddir to at_top_build_prefix.

4261 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4263 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4264 of confdefs.h .
4266 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4268 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4269 argument to m4_foreach. I guess it was necessary in the past,
4270 but I think it's a no-op now.
4272 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4274 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4275 ``cat <<_ACEOF'' commands to one.
4276 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4277 * lib/autoconf/status.m4: On various places, use expr instead of
4278 ``echo|sed.''
4279 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4280 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4281 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4282 a range.
4283 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4284 the wrong patterns between ``case'' and ``esac.'' The previous
4285 code had false positives.
4287 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4289 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4290 as on 2005-05-02.
4291 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4292 Mention LIBOBJDIR.

4334 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
4335 check.
4336 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4337 enough arguments, similarly as in m4_bpatsubsts.

4346 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4347 for absolute directory names in one loop.
4348 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4349 abbreviations of --version and --debug.
4351 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4353 * doc/autoconf.texi (Autoconf Language): Be more precise about
4354 quoting rules. Problems noted by Stepan Kasal.
4355 Also, throughout this document, be more careful about white space.
4356 "blank", "white space", and "space" all have different meanings
4357 and we should be careful to say what we mean.
4359 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4361 Fix C++ related problems reported by Werner Lemberg.
4362 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4363 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4364 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4365 avoid problems with C++ and throw.

4378 set by latest automake.
4380 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4382 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4383 outputs 0 on GNU/Linux these days.
4385 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4387 * doc/autoconf.texi (Autoconf Language): Add more description
4388 about quoting heuristics.

4391 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4393 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4394 not newline.
4396 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4397 by AC_DEFINE; it was a mistake.
4398 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4400 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4402 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4404 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4406 * doc/autoconf.texi (External Software): Quadrigraphs are not
4407 processed correctly in AS_HELP_STRING; avoid this in the examples.
4408 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4409 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4410 comment and reduce m4_default([foo], []) to [foo].
4411 (m4_strip): Update the explanation.
4413 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4415 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4416 Remove core.conftest.* too; it's generated by Tru64 5.1.
4417 Problem reported by Jennis Pruett.
4418 * lib/autoconf/functions.m4
4419 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4420 Don't bother to remove core files; AC_RUN_IFELSE should do that
4421 for you.
4423 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4425 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.

4465 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4467 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4468 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4469 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4470 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4471 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4473 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4475 * NEWS: The configure command now warns you if you attempt to use
4476 a directory whose name contains a special character like space,
4477 newline, or "\".
4478 * doc/autoconf.texi (Installation Directory Variables): Allow
4479 "," in file names. Do not use \@; it's not a portable regexp.
4480 * bin/Makefile.am (edit): Likewise.
4481 * lib/Makefile.am (edit): Likewise.
4482 * tests/Makefile.am (edit): Likewise.
4483 * tests/semantics.at: Likewise.
4484 * tests/torture.at: Likewise.
4485 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.

4488 unportable file names.
4489 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4490 (AC_INIT): Use it.
4491 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4492 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4493 ac_pwd, and quote srcdir.
4494 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4496 * doc/autoconf.texi: Fix some systematic formatting problems.
4497 ".)" needs a following @: if not at the end of a sentence, and
4498 similarly for "!)". "etc." should be preceded by a comma.
4499 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4501 2005-03-22 Bruno Haible <bruno@clisp.org>
4503 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4504 argument is often called 'build-aux'.
4506 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4508 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4509 macro AC_TRY_LINK is obsolete.
4510 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4511 `AC_CONFIG_FILES'.
4513 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4515 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4516 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4517 from a Common Lisp's `cl'.
4518 (AC_PROG_CXX): Behave according to the documentation: don't
4519 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4520 make the variable CCC precious; use `cl.exe', not `cl'.

4523 Alexandre Duret-Lutz <adl@gnu.org>
4525 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4526 /dev/null, as "configure" shouldn't read stdin, and this insulates
4527 us from problems (e.g., when testing for "cl"). Also, do this
4528 redirection before invoking "hostname" or "uname", and keep the
4529 original input stream available via...
4530 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4531 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4532 bother with "</dev/null" since it's now done at the top of
4533 'configure'.
4534 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4535 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4536 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.

4541 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4543 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4544 newline if neither \c nor -n work, as that would output two
4545 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4547 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4549 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4550 This causes that any required macros inside will get before the if.
4551 * doc/autoconf.texi (autom4te.cache): A typo.
4553 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4555 Undo previous change, except keep the change to
4556 lib/autoconf/programs.m4 that replaced grep with shell
4557 pattern-matching. This is because net-snmp configure reads stdin.
4558 Reported by Noah Misch.
4560 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4562 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4563 from /dev/null, as "configure" shouldn't read stdin, and this
4564 insulates us from problems (e.g., when testing for "cl").
4565 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4566 before invoking "hostname" or "uname".
4567 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4568 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4569 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4570 "</dev/null" since it's now done at the top of 'configure'.
4571 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4572 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4573 Also, replace grep with shell pattern-matching, to save a process.
4575 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4577 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4578 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4579 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4580 compiler.
4582 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4584 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4585 grep -q isn't portable. Improve grep -s explanation.
4586 Problem reported by Dan Manthey.
4588 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4590 * doc/autoconf.texi (Special Shell Variables): Clarify
4591 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4593 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4595 * doc/autoconf.texi: Use @acronym for DJGPP.
4596 Fix some @code's that should have been @env's, and vice versa.
4597 Sort environment variable names.
4598 Mention that shells no longer inherit IFS.
4599 Don't recommend PATH_SEPARATOR=';' so strongly.
4600 Mention that $RANDOM might expand to the empty string.
4601 "symlink" and "soft link" -> "symbolic link".
4602 Improve mktemp description (reported by Bruno Haible).
4604 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
4606 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
4607 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
4608 Likewise.

4614 * NEWS: Mention AT_COPYRIGHT.
4616 * tests/local.at (AT_CMP): Use diff directly on input files rather
4617 than copying them.
4619 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
4620 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).

4623 and Paul Eggert <eggert@cs.ucla.edu>

4636 (Standard regular expressions): New test.
4637 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
4638 excess test name quoting.
4639 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
4640 CPPFLAGS to `configure' instead of setting it in `configure'.
4642 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
4643 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
4644 on some platforms.
4646 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
4647 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

4675 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
4677 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
4678 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
4680 Try not to generated lines of unlimited length, as POSIX places a
4681 2047-byte limit on line length of portable text files.
4682 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
4683 Use newline as a separator, not space.
4684 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
4685 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
4686 space.
4688 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4690 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
4691 as_func_*. Add test to check whether positional parameters
4692 are restored after function return.
4694 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
4696 * doc/autoconf.texi (Special Shell Variables): Mention _,
4697 BIN_SH, DUALCASE. Say that variables other than "status" are safe
4698 if they contain a lower-case letter. The DUALCASE problem was
4699 reported by Ralf Wildenhues.
4701 * bin/autoconf.as: Don't exit with status 0 after write failure
4702 with --help or --version.
4703 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

4714 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
4716 * man/Makefile.am (.x.1): Go back to the simple solution, but take
4717 care to echo the commands, so the user knows what's going on.
4718 Modified from a suggestion by Stepan Kasal.
4720 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

4741 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
4742 Update the long comment explaining it.
4744 m4_require no longer writes an ``is required by'' line to the
4745 execution stack. It contains only one bit of non-redundant
4746 information: that the macro was required, not called. And even
4747 this bit is useless in most situations: have you ever met a macro
4748 which both calls and requires the same macro?
4750 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
4751 (_m4_defun_pro_outer): ... only via this macro, for the outermost
4752 macro.
4753 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
4754 (m4_expansion_stack_pop): Remove the misplaced comment.
4755 (m4_require): Don't put the ``is required by'' line to the
4756 execution stack; slightly improve the out-of-a-defun error message.
4757 (_m4_divert_grow): New macro, counter for the temporary diversions.
4758 (_m4_require_call): Use it.
4759 * tests/m4sugar.at (m4_require): Expect output without the
4760 ``is required by'' messages.
4762 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
4764 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
4765 rather than x for expr.
4767 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
4768 this is safe.
4769 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
4770 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

4780 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm
4781 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
4782 from masters, so that FileUtils.pm's update_file provide --force
4783 support.
4784 * bin/autoheader.in: Pass $force to update_file so that
4785 config.h.in is always recreated when --force.
4787 2005-01-24 Stepan Kasal <kasal@ucw.cz>
4789 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
4791 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
4793 * doc/autoconf.texi (Limitations of Builtins): Clarify that
4794 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
4796 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
4798 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
4799 Warn about newline stripping in `` and $(). Update Solaris
4800 version to 9.
4801 (Limitations of Builtins): Use expr "X...", not expr "x...", as
4802 X insulates us from future changes to Posix.
4803 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
4804 stripping.
4806 2005-01-19 Stepan Kasal <kasal@ucw.cz>
4808 * doc/autoconf.texi (Defining Symbols): Delete the false comment that
4809 you cannot use AC_DEFINE to define macros containing `[' or `]'.
4811 2005-01-13 Paul Eggert <eggert@cs.ucla.edu>
4813 * doc/autoconf.texi (Limitations of Usual Tools): Document bug

4824 ulongval to be static, to avoid unwanted GCC warning. Problem
4825 reported by Michael Jennings via Daniel Reed; see
4826 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
4828 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
4830 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

4832 datadir, infodir, and mandir. Adjust argument parsing code.
4833 (_AC_INIT_HELP): Update help text.

4835 new variables.
4837 2005-01-04 Noah Misch <noah@cs.caltech.edu>
4839 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
4840 not seem to work, assume it does set $(MAKE).
4841 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
4843 2005-01-03 Stepan Kasal <kasal@ucw.cz>
4845 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

4851 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
4852 (_m4_divert_n_stack): New macro; the expansion is
4853 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
4854 otherwise.
4855 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
4856 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
4857 stored in _m4_divert_diversion or _m4_divert_dump.
4858 (m4_divert_pop): When the parameter is given, compare the symbolic
4859 name with the last diversion pushed on the stack. Previously, the
4860 current diversion was compared with the numeric value of the
4861 diversion given as the parameter.
4862 (m4_require): If the macro hasn't been expanded yet, call ...
4863 (_m4_require_call): this new macro.

4896 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE
4897 signals that the package uses Automake; a `Makefile.am' is typical but
4898 not essential. Reported by Magnus Therning.
4899 * tests/torture.at (autoreconf.): New banner.
4900 (autoreconf and non-AC configure): Rename to `Non-Autoconf
4901 AC_CONFIG_SUBDIRS'.

4945 AT_LINE is used for log files.
4947 2004-12-21 Stepan Kasal <kasal@ucw.cz>
4949 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
4950 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are
4951 no longer part of the macro, quote the occurrence of ``$tmp''.
4952 * doc/autoconf.texi (Forbidden Patterns): Typo.

5170 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

5173 overflow on signed char hosts.

5289 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5290 "/usr/include", clear ac_x_includes instead of leaving it as "no"

5422 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5423 Don't fail if ENV or BASH_ENV is readonly.
5424 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5425 etc. are read only. Problem reported by Ludovic Courtes.
5427 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5429 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5430 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5431 (trivial change)
5433 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5435 * doc/autoconf.texi (File System Conventions): Warn about
5436 names like "aux". Problem reported by Eric Blake.
5438 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5439 by zero instead of array size, so that we can use any arithmetic
5440 constant expression (instead of requiring an integer constant
5441 expression). This allows us to test expressions like DBL_MAX <
5442 LDBL_MAX, which didn't conform to the C standard using the old
5443 method.
5444 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5445 now that we can do floating-point tests at compile time.
5447 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5449 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5450 and LDBL_EPSILON, as the resulting expression isn't an
5451 integer constant expression and violates the C standard.
5452 Problem reported by Nelson H. F. Beebe. Also, check
5453 for "L" suffix, and check that long double doesn't have
5454 worse range or precision than double, that mixed-mode
5455 arithmetic doesn't generate a diagnostic, that double
5456 constants fit in long double.
5458 2004-06-03 Kevin Ryde <user42@zip.com.au>
5460 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5461 malloc(0) and realloc(NULL,size).
5463 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5464 Bob Proulx.
5466 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5468 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5469 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5470 by Jim Meyering.
5472 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5474 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5475 can be rewritten using if-then-else. Suggested by Bruno Haible.
5477 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5479 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5480 Problem reported by Stepan Kasal.
5482 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5484 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5485 change). Patch reported by Ralf Wildenhues in
5486 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5488 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5489 function F exists if the compiler and linker let you compile an
5490 expression like (F != 0). Recent versions of GCC optimize away
5491 the reference to F in that case, since every function address must
5492 be nonzero, so the link succeeds even if F does not exist.
5493 Problem reported by Manu in
5494 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5496 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5497 "Unix". Many uses changed.
5498 (Limitations of Builtins): Explain better why the ! command isn't
5499 portable.
5501 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5503 * lib/autom4te.in (Automake-preselections): Preselect
5504 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5506 2004-05-19 Kevin Ryde <user42@zip.com.au>
5508 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5509 referencing AC_FUNC_STRERROR_R.
5511 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5512 note pessimistic assumption when cross compiling.
5514 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5516 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5517 (until 2004) invoked subcommands with sh -e, contra POSIX.
5518 Reported by Kevin Ryde.
5520 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5522 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5523 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5524 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5525 `test -f " /usr/bin/grep"', which _always_ failed.
5526 (AC_PROG_SED): Ditto bogus PATH fix.
5527 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5528 requires that grep correctly supports _multiple_ `-e' options, rather
5529 than stating only that grep should accept `-e'.
5531 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5533 Port to C99, which requires that 'exit' be declared.
5535 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5536 to ensure that stdlib.h is included.
5537 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5538 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5539 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5540 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5541 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5542 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5543 when using 'exit' in a test; C99 requires that 'exit' be declared.
5545 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5547 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5548 now prefers 'grep' implementations that accept -e.
5549 (Limitations of Usual Tools): Describe problems of traditional
5550 egrep and fgrep with long input lines, and of traditional grep
5551 with -e.
5552 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5553 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5554 All callers changed. Append /usr/xpg4/bin to the PATH, for
5555 Solaris.
5556 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5557 the user with complaints about multiple -e options.
5558 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5559 Define it with AC_PROG_GREP.
5560 * configure.ac (AC_PROG_GREP): Add.
5561 * lib/freeze.mk (GREP): New macro.
5563 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5565 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5566 a possible candidate only after all others fail, rather than
5567 consulting it first. This improves backward compatibility by
5568 better reflecting the way shell selection occurred in previous
5569 versions of Autoconf, and should help to avoid triggering latent
5570 problems in other packages, such as the one in Automake where zsh
5571 is not handled robustly:
5572 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5573 Although it is not Autoconf's responsibility to work around
5574 problems in Automake, it nevertheless makes sense to avoid
5575 introducing unnecessary incompatibilites.
5577 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5578 Gary V. Vaughan <gary@gnu.org>
5580 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5581 how deeply nested we are when a suitable tool is found, set the
5582 ac_path_TOOL_found flag.
5583 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5584 nested we are in this macro. Break out of all 3 nested loops if
5585 ac_path_TOOL_found is set.
5587 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5589 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5590 of the _AS_PATH_WALK loop too if GNU flavor is found.
5592 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5594 * doc/autoconf.texi (Limitations of Make): Update documentation
5595 for `$<'. New entry `Long lines', based on a report from Simon
5596 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5597 paragraph about DJGPP, based on a mail from Richard Dawe.
5599 2004-04-20 Paul Eggert <eggert@twinsun.com>
5601 * tests/c.at (C keywords): Don't assume that GCC supports
5602 "restrict" and "inline", as sufficiently-old GCC versions do not
5603 (also, GCC configured to be in pedantic C89 mode does not).
5604 Problem reported by Sumit Pandya in:
5605 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5607 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5608 consider -g to work if it generates warnings when plain compiles
5609 don't. Problem reported by Braden McDaniel in:
5610 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5612 * doc/autoconf.texi (Slashes): New section, to document a problem
5613 reported by Jim Meyering in:
5614 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5616 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5617 linker output files before linking, to work around IRIX 6 linker bug.
5618 Problem reported by Rainer Orth in:
5619 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5621 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5623 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5624 best tool so far counter rely on the tool path variable name to
5625 avoid checks for one tool being affected by the results of running
5626 the length check on a previous tool.
5628 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5629 match expression argument, as different greps have different
5630 regular expression flavours.
5631 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5632 literals.
5633 (AC_PROG_EGREP): Pass 'EGREP$'.
5634 (AC_PROG_GREP): Pass 'GREP$'.
5636 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
5638 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
5639 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
5641 2004-03-29 Paul Eggert <eggert@twinsun.com>
5643 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
5644 Types, Specific Compiler Characteristics, System Services,
5645 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
5646 etc. consistently instead of 'long', 'short', 'unsigned' etc.
5647 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
5648 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
5649 Likewise.
5650 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
5651 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
5652 AC_TYPE_OFF_T): Likewise.
5653 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
5654 Likewise.
5656 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
5657 pacify libtool 1.5.2. Fix quoting problems in sed command.
5659 2004-03-28 Paul Eggert <eggert@twinsun.com>
5661 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
5662 now defines HAVE_DECL_TZNAME if it is declared, when
5663 HAVE_STRUCT_TM_TM_ZONE is not defined.
5664 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
5665 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
5666 for HAVE_TZNAME.
5668 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
5670 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
5671 superfluous backslashing of quotes (") in sed expressions;
5672 thanks to Paul Eggert.
5674 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
5676 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
5677 Fortran compiler is ifort, also added pghpf; thanks to Nelson
5678 H. F. Beebe for the bug report.
5680 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
5682 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
5683 quoted -cmdline argument in Portland Group compiler (bug
5684 reported by Jeffrey J. Barteet).
5686 2004-03-25 Kevin Ryde <user42@zip.com.au>
5688 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
5689 (Run Time): ... here, where it's now mentioned.

5710 AC_CHECK_TOOLS.
5711 (Specifying Names): Document the reason for these future
5712 behavioral changes.
5713 * tests/mktests.sh: Do not generate tests for the
5714 new macros.
5715 * NEWS: Document these changes.
5717 * doc/autoconf.texi: Avoid macros with unbraced arguments,
5718 they make TeX hang up.

5722 * NEWS: New macro AC_CHECK_ALIGNOF.
5723 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
5724 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
5725 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
5726 vowel.
5727 (AC_CHECK_ALIGNOF): New macro.
5728 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
5729 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
5730 those for sizeof.
5732 2004-03-03 Paul Eggert <eggert@twinsun.com>
5734 * bin/Makefile.am (edit): Don't use $< in a context where
5735 POSIX doesn't require support for it. Use $@.in instead.
5736 Problem reported by Anthony N. Frasso in
5737 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
5738 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
5740 2004-02-23 Gary V. Vaughan <gary@gnu.org>
5742 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
5743 from the next generation of Libtool.

5766 AC_SUBST provides no portable way to escape literal newlines.
5768 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
5769 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
5770 Darwin uses -lcrt2.o and there's little point to cataloging all
5771 the system variants. Partial fix reported by Andreas Waechter in:
5772 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
5773 for bug reported by Nelson H. F. Beebe in:

5786 refer to the correct file.
5787 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
5788 the behavior of the third argument.
5789 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
5790 correctly the behavior of the third argument. Document
5791 what the three macros that AU_DEFUN defines do. Fix
5792 warning message when the third argument includes $0
5793 (reported by Alexandre Duret-Lutz).

5796 Eric Sunshine <sunshine@sunshineco.com>
5797 Paul Eggert <eggert@twinsun.com>
5799 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
5800 (AS_INIT): Output shell initialization there. Removed optional
5801 parameter. Expand _AS_SHELL_FN_SPY.
5802 (AS_INIT_WITH_SHELL_FN): Removed.
5803 (_AS_SHELL_FN_SPY): New macro.
5804 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
5805 macros.

5807 and documentation for the parameter.
5808 (_AS_DETECT_BETTER_SHELL): Move it here.

5810 (_AS_RUN): Move it here, support testing with eval.
5811 (AS_REQUIRE_SHELL_FN): Require shell functions when
5812 it is used.

5816 use AS_INIT_WITH_SHELL_FN.
5817 * bin/autoconf.in, tests/wrapper.in: Regenerated.
5819 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

5823 is broken.
5824 * lib/autoconf/autoupdate.m4 (AU_DEFINE): New dummy macro.
5825 (AU_DEFUN): Honor the third parameter, create autoupdate
5826 macros with AU_DEFINE.

5846 copyright years.
5847 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
5848 2003 (except 1997) to the list of copyright years. This undoes
5849 the 2003-05-22 change, which removed the older years from the list.
5850 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
5852 2004-01-27 Gary V. Vaughan <gary@gnu.org>

5858 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
5859 AC_PROG_GREP.
5860 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
5861 egrep and fgrep respectively if $GREP -E/-F don't work.
5862 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
5863 _AC_PROG_GREP, and AC_PROG_SED.
5864 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
5865 longest input length accepted by a command.
5866 (AC_PROG_SED): Use it.
5867 * doc/autoconf.texi (Particular Programs): Document the changes.
5868 * NEWS: Updated.
5870 2004-01-27 Paul Eggert <eggert@twinsun.com>
5872 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
5873 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
5874 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
5875 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
5877 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
5878 bin/autoconf.in, config/Makefile.in, config/config.guess,
5879 config/config.sub, config/install-sh, config/mdate-sh,

5894 2004-01-26 Paul Eggert <eggert@twinsun.com>
5896 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
5897 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
5898 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
5899 not <inttypes.h>. Problem reported by Tim Mooney in
5900 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
5901 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
5902 Likewise.
5904 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
5905 otherwise "make check" fails because it forbids cmp (I guess
5906 because cmp treats files as binary on DOS-like systems).
5908 * tests/mktests.sh: Update copyright date to 2004, since some tests
5909 have changed in 2004.
5911 2004-01-23 Gary V. Vaughan <gary@gnu.org>
5913 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
5914 non-truncating sed or gsed program in PATH.
5915 * tests/acprograms.at: Add it.
5916 * doc/autoconf.texi (Particular Programs): Document it.
5917 * NEWS: Updated.
5919 2004-01-15 Paul Eggert <eggert@twinsun.com>
5921 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
5922 -std1 disables some useful extensions on Tru64. Problem reported
5923 by N. Lichtmaier in
5924 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
5926 2004-01-14 Paul Eggert <eggert@twinsun.com>
5928 * doc/autoconf.texi (Programming in M4sh): Document that
5929 AS_MKDIR_P succeeds if the destination is a symbolic link
5930 to an existing directory.
5931 (Limitations of Usual Tools): Note that mkdir -p might not
5932 succeed on symlinks to directories.
5934 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
5936 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
5937 * bin/autoheader.in: Grammar fix in message.
5938 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
5939 Test for dir before calling mkdir -p. (trivial changes)
5941 2004-01-13 Eric Blake <ebb9@byu.net>
5943 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
5944 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
5946 2004-01-10 Jim Meyering <jim@meyering.net>
5948 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
5950 2004-01-09 Paul Eggert <eggert@twinsun.com>
5952 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
5953 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
5954 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
5955 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
5956 AC_COMPILE_IFELSE, since we now assume our caller invokes
5957 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
5958 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
5959 of AC_RUN_IFELSE; this avoids the warning mentioned above.
5960 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
5962 2004-01-07 Paul Eggert <eggert@twinsun.com>
5964 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
5965 `"'...'"`, as it's confusing (and I suspect it may not work on
5966 some platforms). The code was incorrect anyway, as it assumed
5967 that \$ evaluated to itself in that context. Reported by
5968 Alexandre Duret-Lutz.
5970 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
5972 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
5973 and _LT_AC_TAGCONFIG.
5975 2004-01-06 Paul Eggert <eggert@twinsun.com>
5977 * doc/autoconf.texi (One Macro Call): Fix an incorrect
5978 example, and add more examples. Reported by Eric Sunshine.
5980 2004-01-05 Paul Eggert <eggert@twinsun.com>
5982 * doc/autoconf.texi (Limitations of Usual Tools):
5983 Remove warning against "rm -fr" introduced yesterday; it
5984 was a false alarm.
5986 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
5987 autoscan, autoupdate, ifnames): Don't use chmod -w.
5988 * lib/Makefile.am (autom4te.cfg): Likewise.
5989 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
5990 "chmod -w".
5992 2004-01-04 Paul Eggert <eggert@twinsun.com>
5993 Paolo Bonzini <bonzini@gnu.org>
5995 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
5996 by doing lineno substitution only on lines containing "$LINENO".
5998 2004-01-04 Paul Eggert <eggert@twinsun.com>
6000 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
6001 Use "rm -f" to remove conftest.sed, not plain "rm".
6002 Bug reported by David Relson in
6003 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6005 * Makefile.am (autom4te-update):
6006 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
6007 * Makefile.maint (my-distcheck, do-po-update): Likewise.
6008 * doc/autoconf.texi (Guidelines): Likewise.
6009 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
6010 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.

6013 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
6014 * tests/Makefile.am (clean-local): Likewise.
6015 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
6016 srcdir): Likewise.
6017 * doc/autoconf.texi (Limitations of Usual Tools):
6018 Warn against "rm -fr".
6020 2004-01-03 Paul Eggert <eggert@twinsun.com>
6022 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6023 -c -o might not work. From a suggestion by Kevin Ryde.
6024 (C Compiler, Generating Sources, Limitations
6025 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6026 Don't put '-o' after non-options, as POSIX doesn't allow this.
6027 Mention that cc's name might be gcc or c89 or whatever.
6029 2004-01-04 Kevin Ryde <user42@zip.com.au>
6031 * doc/autoconf.texi: Add various further index entries.
6033 2003-12-29 Paul Eggert <eggert@twinsun.com>
6035 * bin/autoreconf.in (autoreconf_current_directory):
6036 Fix typo: mkdir without umask arg.
6038 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6040 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6041 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6042 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6043 explanation clearer.
6045 2003-12-24 Andreas Schwab <schwab@suse.de>
6047 * doc/autoconf.texi (Default Includes): Fix misspelling of

6052 * configure.ac: Test if sh -n works.
6053 * configure: Regenerate.
6054 * tests/atlocal.in: Store the result here.
6055 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
6056 tools.at, looking in atlocal's ac_cv_sh_n_works instead
6057 of explicitly testing.
6058 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
6059 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
6060 * tests/tools.at (Syntax of the shell scripts): Simplify
6061 using AT_CHECK_SHELL_SYNTAX.

6075 Extracted from AS_SHELL_SANITIZE.
6076 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
6077 macros.
6078 (AS_SHELL_SANITIZE): Move reinvocation code from
6079 _AS_LINENO_WORKS, use it to find out if shell
6080 functions work.
6081 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6082 does not work.
6083 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
6084 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

6102 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6145 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
6146 than $target since the latter is not usual, add guidelines on when to

6330 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
6331 pattern-matching instead of grep.
6333 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6335 * doc/autoconf.texi: Document new FC Fortran macros.
6337 2003-10-08 Gary V. Vaughan <gary@gnu.org>
6339 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Stub out a macro
6340 that future autopoint/aclocal/automake/autoreconf will be able
6341 to trace to find where to install local m4 macros.
6342 * doc/autoconf.texi (Input): Document it.
6343 * NEWS: Updated.
6345 2003-10-06 Gary V. Vaughan <gary@gnu.org>
6347 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Add
6348 -lcrtbegin.o to list of ignored flags and fix underquoting of
6349 -lcrt[01].o.
6351 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6353 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6354 cache variable instead of $G77 to decide whether to include -O2,
6355 since $G77 is specific to Fortran 77.
6357 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6359 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6360 free" flag. Re-order flags tested into rough order of popularity.
6362 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6364 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6365 arguments so that it can be used with syntax identical to
6366 AC_PROG_F77, and so that we can more easily decide to
6367 remove/deprecate the DIALECT optional argument in the future if it
6368 proves troublesome.
6369 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
6370 non-freeform-supporting compilers. Document freeform flags.
6372 2003-10-03 Akim Demaille <akim@epita.fr>
6374 * configure.ac: Look for emacs, not macs.
6375 Reported by Eric Sunshine.
6377 2003-10-03 Akim Demaille <akim@epita.fr>
6379 * lib/autom4te.in (Autoreconf-preselections): Trace AC_CONFIG_AUX_DIR.
6380 * bin/autoreconf.in (autoreconf_current_directory): Create the
6381 AUX_DIR if needed, for sake of automake --add-missing etc.
6382 Suggested by Alexandre Duret-Lutz.
6384 2003-10-03 Akim Demaille <akim@epita.fr>
6386 * configure.ac: Quotation and formatting changes.
6387 (EMACS): Don't set it if it is not recent enough to support
6388 autoconf-mode.el.
6389 From Eric Sunshine.
6391 2003-10-02 Akim Demaille <akim@epita.fr>
6393 * bin/ifnames.in (&scan_file): Skip C++ comments.

6403 Version 2.57f.
6405 2003-09-30 Paul Eggert <eggert@twinsun.com>
6407 * lib/Autom4te/XFile.pm: Use Errno.
6408 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
6409 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
6411 2003-09-30 Akim Demaille <akim@epita.fr>
6413 * config/announce-gen (&print_news_deltas): Extracted from...
6414 (&print_changelog_deltas): here.
6415 (&news_file): Rename as...
6416 (@news_file): this.
6418 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
6420 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
6421 have been created when invoking the compiler.
6422 * tests/fortran.at (GNU Fortran 77): Quote $G77.

6426 Version 2.57e.
6428 * config/mkinstalldirs: Upgrade.
6430 2003-09-28 Paul Eggert <eggert@twinsun.com>
6432 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
6433 Problem reported by Lars J. Aas in
6434 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6435 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6436 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6437 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6439 2003-09-26 Akim Demaille <akim@epita.fr>
6441 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6442 directory for AC_CONFIG_COMMANDS' first argument exists.
6443 This makes valid the invocation of _AC_SRCPATH that follows.
6444 Reported by Eric Sunshine.
6445 * doc/autoconf.texi (Configuration Commands): Adjust.
6447 2003-09-26 Akim Demaille <akim@epita.fr>
6449 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6450 Reported by Ralf Corsepius.
6452 2003-09-26 Akim Demaille <akim@epita.fr>
6454 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6455 arguments.
6456 Actually, use AU_ALIAS.
6457 From Bruno Haible.
6459 2003-09-26 Paul Eggert <eggert@twinsun.com>
6461 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6462 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6463 Problem reported by Eric Sunshine in:
6464 http://mail.gnu.org/archive/html/autoconf-patches/2002-12/msg00014.html
6466 2003-09-26 Akim Demaille <akim@epita.fr>
6468 The test suite are sometimes assigning timings incorrectly.
6469 Reported by Henk Krus.
6470 Diagnosed by Nicolas Joly.
6472 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6473 AT_help_all.
6474 Instead of making AT_help a sequence of assignments to grow
6475 $at_help_all, just make AT_help_all be the growing contents of
6476 $at_help_all, and make a single assignment in...
6477 (AT_INIT): here.
6478 (at_times_skip): Flip the meaning and rename as...
6479 (at_times_p): this.
6480 (AT_INIT): When summarizing the test that ran, remove
6481 $at_times_file after use, and check it is present before trying to
6482 use it.
6484 2003-09-25 Akim Demaille <akim@epita.fr>
6486 Version 2.57d.
6488 * bin/Makefile.am (edit): Handle '@configure_input@'.
6489 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6490 (ifnames): chmod -w.
6491 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6492 executables, not bin/ executables! Otherwise all the magic needed
6493 to find non installed files is turned off. This caused a failure
6494 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6495 as found in its environment (sent by tests/autoreconf): pointing
6496 to bin/autom4te that could not find its files.
6497 * tests/mktests.sh: Force the replacement of generated files, for
6498 the sake of "mv" program that are interactive when overwriting a
6499 -w file.
6500 * config/install-sh: Upgrade from CVS Automake.
6502 2003-09-23 Paul Eggert <eggert@twinsun.com>
6504 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6505 versus test -L issues.
6507 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6508 Paul Eggert <eggert@twinsun.com>
6510 Trivial change to support GCC's configuration procedure.
6511 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6512 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6513 about inconsistency if the preprocessor is set to give errors for
6514 any warning.
6515 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6517 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6519 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6520 and XFile.pm from Automake.
6521 * lib/Autom4te/XFile.pm: Update from Automake.
6523 2003-09-12 Akim Demaille <akim@epita.fr>
6525 Version 2.57c.
6527 2003-09-12 Akim Demaille <akim@epita.fr>
6529 * config/config.guess, config/config.sub, config/missing,
6530 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
6531 from masters.
6533 2003-09-12 Akim Demaille <akim@epita.fr>
6535 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6536 not asm/types.h.
6538 2003-09-11 Akim Demaille <akim@epita.fr>
6540 * doc/autoconf.texi (Header Portability): linux/random.h.
6541 From Peter Hendrickson.
6543 2003-09-10 Akim Demaille <akim@epita.fr>
6545 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6546 willing to edit the output files.
6548 2003-09-10 Akim Demaille <akim@epita.fr>
6550 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6551 and AC_FC_FREEFORM.
6552 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6553 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6555 2003-09-09 Akim Demaille <akim@epita.fr>
6557 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
6558 Reported by Gary Vaughan.
6559 * bin/autom4te.in (handle_m4): Likewise.
6561 2003-09-09 Akim Demaille <akim@epita.fr>
6563 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
6564 trailing files.
6566 2003-09-07 Paul Eggert <eggert@twinsun.com>
6568 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6569 Improve the accuracy of the wording about obsolescence.
6570 From a suggestion by Ian Lance Taylor in
6571 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6573 2003-09-05 Paul Eggert <eggert@twinsun.com>
6575 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6576 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6578 2003-09-04 Akim Demaille <akim@epita.fr>
6580 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6581 AC_FUNC_WAIT3.
6583 2003-09-04 Akim Demaille <akim@epita.fr>
6585 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6586 (freeze): When exiting, use $exit_code.
6587 * lib/autoconf/fortran.m4: Comment changes.
6589 2003-09-04 Akim Demaille <akim@epita.fr>
6591 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6593 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6595 Add support for newer Fortran dialects. The F77 interface is
6596 unchanged, and continues to support Fortran 77. New FC macros
6597 correspond to all the old F77 macros, with output variables FC,
6598 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6599 available dialect, but older dialects can be specified. There are
6600 new macros AC_FC_SRCEXT to set the source extension, and
6601 AC_FC_FREEFORM to accept free-form source files.
6603 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6604 New macros.
6605 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
6606 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,
6607 _AC_LANG_ABBREV(Fortran), _AC_LANG_PREFIX(Fortran 77),
6608 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

6610 AC_LANG_PREPROC(Fortran), AC_LANG_COMPILER(Fortran),
6611 _AC_FC_DIALECT_YEAR, _AC_F95_FC, _AC_F90_FC, _AC_F77_FC,

6615 AC_FC_DUMMY_MAIN, _AC_FC_MAIN, AC_FC_MAIN, __AC_FC_NAME_MANGLING,
6616 _AC_FC_WRAPPERS, AC_FC_WRAPPERS, _AC_FC_FUNC, AC_FC_FUNC,
6617 AC_FC_SRCEXT, AC_FC_FREEFORM):
6618 New macros.
6619 (AC_PROG_F77, AC_PROG_F77_C_O, AC_F77_LIBRARY_LDFLAGS,
6620 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6621 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6622 Rewrite in terms of the above.
6623 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6624 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
6625 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
6626 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
6628 2003-09-02 Paul Eggert <eggert@twinsun.com>
6630 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6631 Document problems with timestamp resolution that 'make', 'cp -p', and
6632 'touch -r' have.
6634 2003-08-27 Akim Demaille <akim@epita.fr>
6636 * tests/m4sugar.at (cross_warning): Make sure to enable the
6637 output, so that we can track spurious m4sugar output.
6638 * tests/local.at: Require 2.57.
6639 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
6640 are defaulted by AT_CHECK anyway.
6641 Use AT_CHECK_AUTOM4TE.
6642 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
6643 missing dnl.
6645 2003-08-27 Akim Demaille <akim@epita.fr>
6647 * bin/autoheader.in: Issue the "Using auxiliary..." message only
6648 when -Wobsolete is set.
6649 Set it on by default.
6650 Suggested by Klee Dienes.
6652 2003-08-27 Akim Demaille <akim@epita.fr>
6654 * doc/autoconf.texi (AC_FUNC_FSEEKO, AC_SYS_LARGEFILE): More
6655 documentation.
6656 From Guido Draheim.
6658 2003-08-26 Akim Demaille <akim@epita.fr>
6660 * doc/autoconf.texi (Output): Make clear that one can run code
6661 after AC_OUTPUT.
6663 2003-08-25 Akim Demaille <akim@epita.fr>
6665 * config/announce-gen, GNUmakefile, Makefile.maint: Update from
6666 CVS Bison.
6668 2003-08-25 Alexandre Duret-Lutz <adl@gnu.org>
6670 * bin/autoreconf.in (parse_args): Do not pass --no-force to

6684 Version 2.57b.
6686 * Makefile.cfg (local-checks-to-skip): New.
6687 * Makefile.maint (local-check): Rename as...
6688 (local-checks-available): this.
6689 (local-check): New.
6691 * Makefile.am (EXTRA_DIST): Add Makefile.cfg.
6692 * configure.ac: Require Automake 1.7.6.
6694 2003-08-22 Akim Demaille <akim@epita.fr>
6696 Output stack traces in warnings.
6698 * lib/m4sugar/m4sugar.m4 (_m4_warn): New.
6699 Replace the former...
6700 (m4_warn): Pass the call stack to _m4_warn.
6701 * bin/autom4te.in: Adjust to output the call stack.
6702 * tests/m4sugar.at (m4@&t@_warn): Adjust.
6704 2003-08-22 Akim Demaille <akim@epita.fr>
6706 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
6707 * bin/autom4te.in: Adjust.
6709 2003-08-21 Akim Demaille <akim@epita.fr>
6711 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
6712 (&verbose): Remove.
6713 (&getopt): Adjust the note and verb channels, depending upon
6714 --verbose.
6715 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
6716 * bin/autoupdate.in: Adjust.
6717 Use &verb, not &verbose.
6719 2003-08-21 Akim Demaille <akim@epita.fr>
6721 * bin/autoheader.in (&parse_args): Use &parse_warnings and
6722 &parse_WARNINGS.
6723 ($help): Use Autom4te::ChannelDefs::usage.
6724 * bin/autoscan.in: Use Autom4te::ChannelDefs.
6725 * lib/Autom4te/General.pm: Don't export error: you don't own it.
6727 2003-08-21 Akim Demaille <akim@epita.fr>
6729 First stab at preserving warnings between calls to autom4te,
6730 including when the cache is used.
6732 There are still several issues: (i) there are too many runs of m4
6733 (one for include, one for warnings, and some more), (ii) warnings
6734 spreading on several lines are not handled gracefully, (iii) the
6735 code meant to have the call stack display for errors does not work
6736 (its handling should move from m4 to autom4te).
6738 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
6739 Use them.
6740 (@preselect): Add m4_warn.
6741 ($exit_status): Remove, use $exit_code.
6742 ($help): Use Autom4te::ChannelDefs::usage.
6743 (&handle_m4): No longer define the m4_warnings.
6744 At each run, extract and report the warnings.
6745 Always cache the result, including if the exit status is on
6746 failure, since if nothing changes, we should result in the same
6747 failure, hence we can use the cache.
6748 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
6749 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
6750 Remove.
6751 (m4_warn): Redefine as a do-nothing: it is its invocation that
6752 matters, as warnings are now reported via traces.
6753 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
6754 the contents of m4_warn: make it _call_ m4_warn, so that tracing
6755 the latter reveals calls to the former.
6757 Adjust the tests.
6759 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
6761 2003-08-21 Akim Demaille <akim@epita.fr>
6763 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
6764 Use them.
6766 2003-08-21 Akim Demaille <akim@epita.fr>
6768 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
6769 forward order.
6770 * lib/Autom4te/ChannelDefs.pm: Doc typos.
6771 (&parse_warnings): Accept a list of warning requests.
6772 (&usage): Return a string, not a side effect.
6773 (cross): New warning category.
6775 2003-08-21 Akim Demaille <akim@epita.fr>
6777 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
6778 (&require_configure_ac): Accept an optional directory argument.
6779 ($configure_ac): Remove.
6780 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
6781 (&catfile): Remove.
6782 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
6783 * bin/autoscan.in: Adjust.
6785 2003-08-20 Akim Demaille <akim@epita.fr>
6787 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
6788 Reported by Alexandre Duret-Lutz.
6790 2003-08-20 Akim Demaille <akim@epita.fr>
6792 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
6793 * bin/autom4te: Adjust.
6794 In particular, be Autoconf tools are really silent when properly
6795 working, bind the verbosity of the 'note' channel to $verbose.
6796 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
6797 (&xsystem, &contents): Remove, since they are exported by...
6798 * lib/Autom4te/FileUtils.pm: this.
6799 More perldoc.
6800 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
6801 * lib/Autom4te/FileUtils.pm: here.

6839 * doc/autoconf.texi (autom4te Invocation): Mention

6845 RUN-IF-PASS optional arguments.

6859 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
6860 shorter column three. Add DESCRIPTION to log file content.
6862 2003-08-13 Derek Price <derek@ximbiot.com>
6864 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
6865 output.
6867 2003-08-12 Derek Price <derek@ximbiot.com>
6869 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
6870 (AT_CHECK_NOESCAPE): Move core functionality to...
6871 (_AT_CHECK): ...this new macro.
6873 2003-08-07 Derek Price <derek@ximbiot.com>
6875 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
6876 (AT_CHECK_NOESCAPE): ...to this new macro.
6878 2003-07-31 Paul Eggert <eggert@twinsun.com>
6880 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
6881 in Bash 2.01. Problem reported by Brian Gough in
6882 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
6884 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
6886 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
6887 -lcrt1.o, for OS X. (trivial change)
6889 2003-07-07 Paul Eggert <eggert@twinsun.com>
6891 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
6892 inside '#ifndef __cplusplus'. Problem reported by
6893 Bob Friesenhahn.
6895 2003-07-06 Bill Clarke <llib@computer.org>
6897 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
6898 'long', not 'int', for benefit of Sun's recent C++ compilers
6899 (trivial change). See:
6900 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
6901 (This really should be 'intptr_t', not 'long', but that would
6902 take more work.)
6904 2003-06-25 Akim Demaille <akim@epita.fr>
6906 * lib/Makefile.am (autom4te.cfg): Make it read only.
6907 Depend on Makefile since it contains substitutions.
6908 From Paolo Bonzini.
6909 * lib/autom4te.in (args): Add local.at? for Autotest args.
6910 This change was made on autom4te.cfg which is generated.
6911 Reported by Raja R. Harinath.
6913 2003-06-25 Akim Demaille <akim@epita.fr>
6915 * doc/autoconf.texi (Header Portability): sys/mount.h.
6916 From Gareth McCaughan.
6918 2003-06-23 Akim Demaille <akim@epita.fr>
6920 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
6921 not all of them. This fixes 1. the fact that when testing
6922 Autoconf there are many many config.log, 2. the incorrect use of
6923 top_srcdir to find config.log.
6924 Don't mix the detailed output of failed test with the summary of
6925 failures. Rather, append detailed log afterwards.
6927 2003-06-23 Akim Demaille <akim@epita.fr>
6929 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
6930 always run: output config.log on $at_group_log.
6932 2003-06-23 Akim Demaille <akim@epita.fr>
6934 * tests/torture.at (#define header templates): Don't use quotes in
6935 C++ comments as it puzzles Emacs' sh font-lock-mode.
6937 2003-06-23 Akim Demaille <akim@epita.fr>
6939 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
6940 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
6941 * tests/atspecific.m4: Rename as...
6942 * tests/local.at: This.
6943 * tests/suite.at: Move the globals into...
6944 * tests/local.at: here.
6945 * tests/Makefile.am: Adjust.
6946 * doc/autoconf.texi (testsuite Scripts): Adjust.
6948 2003-06-21 Kevin Ryde <user42@zip.com.au>
6950 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
6951 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
6952 ensuring we add -std1 for full-ANSI.
6954 * doc/autoconf.texi (hdrindex): New macro.
6955 Add index entries for portability of various standard header files.
6957 2003-06-20 Akim Demaille <akim@epita.fr>
6959 * configure.ac: Bump to 2.57b.
6961 2003-06-20 Akim Demaille <akim@epita.fr>
6963 Version 2.57a.
6965 2003-06-20 Akim Demaille <akim@epita.fr>
6967 * bin/autom4te.in: Don't rely on $HOME being defined.
6968 Reported by Marc Espie as PR/233.
6970 2003-06-20 Akim Demaille <akim@epita.fr>
6972 * lib/autotest/general.m4: Use at_times_file only if used.
6973 From Nicolas Joly.
6975 2003-06-20 Akim Demaille <akim@epita.fr>
6977 * config/config.guess, config/config.sub, config/elisp-comp,
6978 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
6979 Update from masters.
6981 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
6983 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
6984 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
6985 (TEST_SCRIPT): New diversion.
6986 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
6987 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
6988 (AT_INIT): Support for expected failures.
6990 2003-06-02 Akim Demaille <akim@epita.fr>
6992 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
6993 changes.
6994 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
6995 Autoconf nor Automake.
6996 (&contents): New, from Automake.
6997 PODify.
6999 2003-05-28 Paul Eggert <eggert@twinsun.com>
7001 * NEWS, doc/autoconf.texi (Particular Functions),
7002 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7003 is the inverse of localtime.
7005 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7007 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7008 (handle_exec_errors): New function. Work around $! being
7009 altered by WEXITSTATUS.
7010 (xqx, xsystem): Use handle_exec_errors.
7012 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7014 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7015 Do not call `_exit()', simply modify `$?'.
7016 (xsystem): Reset $! before running system, and check it afterward.
7017 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7018 63 for version mismatches.
7020 2003-05-23 Akim Demaille <akim@epita.fr>
7022 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7023 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7024 the middle of a line).
7025 * lib/m4sugar/m4sugar.m4: Likewise.
7026 Remove useless spaces in comments.
7028 2003-05-23 Akim Demaille <akim@epita.fr>
7030 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7031 exit 63, so that we (or Automake's "missing") can tell the
7032 difference with a plain failure.
7033 * doc/autoconf.texi (Notices): Adjust.
7035 2003-05-23 Akim Demaille <akim@epita.fr>
7037 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7038 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7039 White spaces cleanup.
7041 2003-05-22 Jim Meyering <jim@meyering.net>
7042 Paul Eggert <eggert@twinsun.com>
7044 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7045 Remove `#include <stdlib.h>' from the list; we should never
7046 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7047 resulting namespace pollution would cause other tests to fail.
7048 Configure scripts run with some older versions of g++ and HP's
7049 aCC would fail due to such an #include. Problems reported by
7050 Matthew Mueller in <http://bugs.debian.org/120704> and by
7051 Keith Bostic in
7052 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7053 In the test, use the test declaration before including <stdlib.h>,
7054 as that's closer to how it'll be used.
7056 2003-05-23 Akim Demaille <akim@epita.fr>
7058 * doc/autoconf.texi (Header Portability): ucred.h.
7059 From Ian Redfern.
7061 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7063 Overhaul Autotest's logging: generate separate log files
7064 in testsuite.dir/NNN/testsuite.log, and append them to
7065 testsuite.log instead of re-running the test verbosely.
7067 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7068 file descriptor, write 0 to at_status_file instead of setting
7069 at_status=0, initialize some new variables (at_status_file,
7070 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7071 to rerun the tests, instead append the at_group_log to the
7072 at_suite_log when a test fails.
7073 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7074 with the AS_MESSAGE_LOG_FD redirected to stdout.
7075 (AT_CLEANUP): save the output status in $at_status_file
7076 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7077 its original place.
7078 (AT_CHECK): since tests are run with a redirected stdout,
7079 and used to be re-run in verbose mode, turn some $at_verbose
7080 into echo, and don't redirect the output of testing stdout
7081 and stderr.
7083 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7084 the name of the debugging directory and information about
7085 its contents.
7087 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7089 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7090 parameter.
7092 2003-05-22 Akim Demaille <akim@epita.fr>
7094 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
7095 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
7096 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4
7097 * lib/autoconf/status.m4: Fix and adjust copyright notices.
7099 2003-05-22 Akim Demaille <akim@epita.fr>

7112 Whitespace clean up.
7113 Suggested by Jim Meyering.
7115 2003-05-22 Akim Demaille <akim@epita.fr>
7117 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
7118 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
7119 Reported by Jim Meyering.
7121 2003-05-22 Akim Demaille <akim@epita.fr>
7123 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.
7124 Add AC_HELP_STRING to the obsolete macros section.
7125 Typos.
7126 Use '@.' for sentences that ended in a capital letter.
7127 From Art Haas.

7138 it to eval.
7140 2003-05-21 Akim Demaille <akim@epita.fr>
7142 * bin/autoupdate.in ($m4): Fix quotation.
7143 Reported by Martin Mokrejs.
7145 2003-05-19 Paul Eggert <eggert@twinsun.com>
7147 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:

7154 AC_CHECK_HEADERS_NEW): New tests.
7156 2003-05-17 Akim Demaille <akim@epita.fr>
7158 * lib/autoconf/functions.m4: Use the default includes so that
7159 memcmp be declared before being tested.
7160 Reported by Sander Niemeijer.
7161 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7162 * doc/autoconf.texi (Default Includes): Document
7163 AC_INCLUDES_DEFAULT.
7165 2003-05-17 Akim Demaille <akim@epita.fr>
7167 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
7168 * doc/autoconf.texi (Obsolete Macros): Adjust.
7169 Reported by Werner LEMBERG and Debian Bug 190886.
7171 2003-05-16 Akim Demaille <akim@epita.fr>
7173 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
7174 user name space clashes.
7175 Reported by Bruno Haible.
7177 2003-05-16 Akim Demaille <akim@epita.fr>
7179 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
7180 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
7181 them uniform, and more robust to Perl special characters.
7182 Reported by Martin Mokrejs.
7184 2003-05-14 Akim Demaille <akim@epita.fr>
7186 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
7188 2003-05-14 Akim Demaille <akim@epita.fr>
7190 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

7195 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
7196 message.
7197 From Matthias Andree.
7199 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
7201 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
7202 and truncate.
7204 2003-05-06 Akim Demaille <akim@epita.fr>
7206 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7207 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7208 by aclocal.m4 is changed it might require the importing of another
7209 m4 extension file, i.e., aclocal must be run.
7211 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7212 (&parse_args): Use --force with aclocal if required and supported.
7213 (&autoreconf_current_directory): Use &run_aclocal.
7215 2003-05-06 Akim Demaille <akim@epita.fr>
7217 Lock autom4te's cache.
7219 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7220 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7221 argument instead of a file name, so that the request file remains
7222 open during the whole autom4te run.
7223 ($icache_file): New.
7224 (&freeze): Lock the $icache_file.
7226 2003-04-29 Derek Price <derek@ximbiot.com>
7228 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7229 seperator with m4_append_uniq(). It doesn't work.
7230 (AT_CLEANUP): Add `;' to end of at_help_all.
7231 (AT_INIT): Allow --keywords to be specified more than once. When
7232 grepping $at_help_all for keywords, use the field and keyword
7233 seperators to ensure a complete keyword match. Alter at_prev handling
7234 to support the new --keywords behavior.
7236 2003-04-27 Karl Berry <karl@freefriends.org>
7238 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7239 align better with others. I also made some of the individual
7240 entries on one line, for brevity and to make it easier for me to
7241 sort my dir-example file in the Texinfo distribution :).
7243 2003-04-12 Jim Meyering <jim@meyering.net>
7245 * NEWS: Mention the new macro.
7246 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

7263 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,
7264 net/if.h, stdlib.h.

7278 * doc/autoconf.texi (ac, at, ms): Rename these indexes as...
7279 (AC, AT, MS): these.
7280 (shortindexflag, @acindex, @ahindex, @asindex, @atindex, @msindex):
7281 New.
7282 Use them.
7283 * doc/Makefile.am (CLEANFILES): Adjust.
7284 (TEXI2DVI): Make it --batch.
7286 2003-03-31 Derek Price <derek@ximbiot.com>
7288 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
7289 which removed the main loop.

7304 2003-03-28 Akim Demaille <akim@epita.fr>
7306 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
7307 reading the section "Present But Cannot Be Compiled" when the
7308 header causes problems.
7310 2003-03-28 Akim Demaille <akim@epita.fr>
7312 * tests/torture.at (Configuring subdirectories): Require aclocal
7313 1.4, otherwise the test fails, as it does support configure.ac.

7336 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
7337 obsolete AC_HELP_STRING.
7338 (AC_HELP_STRING): AU_DEFUN to...
7339 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
7340 * tests/m4sh.at (AS_HELP_STRING): New test.
7342 * tests/acgeneral.at: Regenerated.
7344 2003-03-26 Derek Price <derek@ximbiot.com>
7346 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
7347 sense. Verbosify the diversion definitions comment.

7366 #line directives.
7367 * lib/autoconf/lang.m4 (AC_LANG_SOURCE): Fix comment to match this.

7370 2003-03-01 Richard Dawe <rich@phekda.freeserve.co.uk>
7372 * tests/atspecific.m4 (AT_CHECK_AUTOM4TE): Normalize
7373 file name for the m4 program, when it has an "exe" file extension.

7384 about `$<' in inference rules, it was a bogus interpretation of
7385 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
7386 Tru64 make in the "target lookup" section.
7387 (Automake): Automake 1.5+ no longer requires special tools to be
7388 present on the developer's host.
7390 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
7392 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
7393 to a shell that can handle redirection or quoting correctly.
7394 Override SHELL with the shell detected by configure.
7395 Use of $^O suggested by Tim van Holder.
7396 * bin/autom4te.in (BEGIN): Likewise.
7397 * bin/autoreconf.in (BEGIN): Likewise.
7398 * bin/autoscan.in (BEGIN): Likewise.
7399 * bin/autoupdate.in (BEGIN): Likewise.
7400 * bin/ifnames.in (BEGIN): Likewise.
7402 * bin/ifnames.in: Add final newline to help and version messages.
7404 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7405 to cope with DOS-style absolute paths, when constructing
7406 ${ac_make}.
7408 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7409 When constructing paths with IFS=:, quote the path. If we're
7410 constructing a DOS-style absolute path, we don't want to split it
7411 on the colon.
7413 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7414 in description.
7416 2003-02-25 Pavel Roskin <proski@gnu.org>

7424 2002-09-01 patch by replacing "test -n" with "test -z".
7425 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
7426 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
7428 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7429 to fix a mismatch between example and discussion.
7431 2003-02-24 Kevin Ryde <user42@zip.com.au>
7433 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7434 format starting with "-".
7436 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7438 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7439 is not portable inside Makefile.
7441 2003-02-20 Akim Demaille <akim@epita.fr>
7443 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7444 compiler says yeah, but preproc says nope, compiler is right.
7445 Conversely, prompt the reader to send a bug report to the
7446 maintainers of the package, not of Autoconf.
7448 2003-02-20 Klee Dienes <kdienes@apple.com>
7450 * bin/autoreconf.in (autoreconf_current_directory): Properly
7451 handle an empty aclocal.m4.

7456 $ac_prefix_program.
7457 From Larry Jones.
7459 2002-12-23 Paul Eggert <eggert@twinsun.com>
7461 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7462 innocuous variant befor including <limits.h> or <assert.h>. This
7463 works around a bug reported by Albert Chin: HP-UX 11i
7464 (and earlier versions) have a <limits.h> that declares
7465 gettimeofday and many other functions.
7467 2002-12-03 Paul Eggert <eggert@twinsun.com>
7469 Version 2.57.
7471 * NEWS, configure.ac: Update version.
7473 * doc/fdl.texi: Upgrade to FDL version 1.2.
7475 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7476 nontrivially in main's body, so that f's external declaration is
7477 not optimized away in AIX. This should fix the bug reported by
7478 Martin Frydl in
7479 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7481 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7482 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7483 defined, to support freestanding compilers. This should fix the
7484 bug reported by Momchil Velkov in
7485 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7487 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7488 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

7493 * Makefile.maint (www-gnu): New macro.
7494 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7495 the location has moved.
7497 2002-12-02 Martin Frydl <martin@systinet.com>
7499 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7500 \(.*\) match is too long and there is something more to be checked.
7501 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7503 2002-11-15 Akim Demaille <akim@epita.fr>

7508 From Paul Eggert.
7509 * config/move-if-change: Indenting changes.
7510 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7511 * configure.ac (AM_INIT_AUTOMAKE): here.
7512 Require 1.7.1.
7514 2002-11-14 Akim Demaille <akim@epita.fr>
7516 Version 2.55.
7518 * config/config.guess, config/config.sub, config/install-sh:
7519 Update from masters.
7521 2002-11-14 Akim Demaille <akim@epita.fr>
7523 * Makefile.maint: Sync with Bison, i.e.:
7524 (po-check): Scan .l and .y files instead of the
7525 .c and the .h files that they generate. This fixes the bug
7526 reported by Tim Van Holder in:
7527 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7528 Look for N_ as well as for _. Try to avoid matching #define for
7529 N_ and _.
7530 From Paul Eggert.
7532 2002-11-14 Akim Demaille <akim@epita.fr>
7534 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7535 From Paul Eggert and Albert Chin-A-Young.
7537 2002-11-14 Akim Demaille <akim@epita.fr>
7539 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7540 From Paul Eggert and Albert Chin-A-Young.
7542 2002-11-14 Kevin Ryde <user42@zip.com.au>
7544 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7545 than assigning in main, to avoid HP cc +O3 optimizing it away.
7547 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7549 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7550 option. Process --recheck after parsing all options. Pass -q
7551 option to configure on --recheck.
7552 (AC_OUTPUT): Pass -q from configure to config.status.
7553 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7554 arguments to record.
7555 * doc/autoconf.texi (config.status Invocation): Document
7556 config.status -q option.
7558 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7560 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7561 Makefile.in if Makefile.am exists.
7562 (output): Strip `.am' from Makefiles. Don't
7563 output AC_CONFIG_FILES if no Makefiles were found.
7565 2002-11-07 Akim Demaille <akim@epita.fr>
7567 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

7572 2002-11-06 Akim Demaille <akim@epita.fr>
7574 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7575 declaration in extern "C" too.

7578 2002-11-06 Akim Demaille <akim@epita.fr>
7580 * tests/torture.at (Configuring subdirectories): Don't use grep
7581 -w.
7582 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7583 Reported by Ezra Peisach.
7585 2002-11-05 Akim Demaille <akim@epita.fr>
7587 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7588 Remove.
7589 We _have_ to stop using the old compatibility scheme that tried to
7590 avoid useless backslashes because Libtool 1.4.3 contains a
7591 AC_DEFINE([error_t], [int],
7592 [Define to a type to use for \`error_t' if it is not
7593 otherwise available.])
7594 We _have_ to quote the single quote and backslashes with \. The
7595 old compatibility scheme saw that ` was backslashed, and therefore
7596 did not quote the single quote. Hence before this patch, Autoconf
7597 was not compatible with Libtool.
7599 2002-11-04 Paul Eggert <eggert@twinsun.com>
7601 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

7612 * config/texinfo.tex: Update.
7614 2002-11-03 Akim Demaille <akim@epita.fr>
7616 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7617 from...
7618 (&autoreconf): here.
7619 ($help, $make, &parse_args, &autoreconf_current_directory):
7620 Support -m/--make.
7621 * doc/autoconf.texi (autoreconf Invocation): Adjust.
7623 2002-10-31 Bruno Haible <bruno@clisp.org>

7637 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
7639 2002-10-31 Akim Demaille <akim@epita.fr>
7641 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
7642 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
7643 Make variable, not a shell variable.
7644 Suggested by Bruno Haible.
7646 2002-10-31 Akim Demaille <akim@epita.fr>
7648 * bin/autom4te.in (load_configuration): Reject #args out of any
7649 language.
7651 2002-10-31 Akim Demaille <akim@epita.fr>
7653 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
7654 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)

7665 Suggested by Tim van Holder.
7667 2002-10-29 Paul Eggert <eggert@twinsun.com>
7669 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
7670 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
7671 Problem reported by Bruno Haible.
7673 2002-10-29 Akim Demaille <akim@epita.fr>
7675 * doc/autoconf.texi (Header Templates): Put also in words what the
7676 pictures says to assist free style readers.
7677 (Customizing autom4te): s/--cache=/--cache /.
7679 2002-10-29 Akim Demaille <akim@epita.fr>
7681 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
7682 sys/wait.h.
7683 sparc_address_test returns void.
7684 Use it with an argument, as prototyped.
7685 From Bruno Haible.
7687 2002-10-29 Akim Demaille <akim@epita.fr>

7702 * doc/autoconf.texi (Invoking autom4te): Rename as...
7703 (autom4te Invocation): this, for consistency with the other nodes.

7988 Reported by Alexandre Duret-Lutz.
7990 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'

7994 (&freeze): Use &error.
7995 (&up_to_date): If a file that was included according to the cache
7996 is no longer there, then the output is out dated.

7998 --force is given.

8009 format, so that Emacs' compile mode understands us.
8010 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8011 if some file was changed instead of `print'.
8012 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.

8046 file name to enable parallel executions.
8047 From Sam Varshavchik.
8049 2002-10-08 Akim Demaille <akim@epita.fr>
8051 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8052 aclocal invocation, as Gettext macros might not be visible to
8053 aclocal.
8054 Instead of blindly running autopoint, scan configure.ac (not the
8055 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8056 Reported by Paul D. Smith.
8058 2002-10-08 Paul Eggert <eggert@twinsun.com>
8060 Work around problems found when POSIXLY_CORRECT=1 is set.
8061 None of this seems to have anything to do with POSIX, really,

8063 * bin/autom4te.in (parse_args): Configure GetOpt with
8064 "permute", too.
8065 * doc/autoconf.texi (Invoking autom4te):

8088 * tests/torture.at (Configuring subdirectories): Be robust to
8089 users who use config.site to require for a cache: in this case,
8090 the two last configure runs, using two different sets of
8091 arguments, trigger a legitimate error.
8093 2002-09-28 Akim Demaille <akim@epita.fr>

8112 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8113 (make, mawk, nawk, ranlib, yacc): Similarly, move to...

8130 (autoscan.list): New target --this file is no longer a source.

8162 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8163 all.
8164 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8165 explicit.
8167 2002-09-28 Akim Demaille <akim@epita.fr>

8283 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8284 is obsolescent.
8286 2002-09-11 Akim Demaille <akim@epita.fr>
8288 * doc/autoconf.texi (Questions): Rename as...
8289 (FAQ): this.

8292 2002-09-09 Akim Demaille <akim@epita.fr>
8294 * doc/autoconf.texi (Making testsuite Scripts): Update.
8295 Suggested by Nishio Futoshi.
8297 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8299 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8300 plain `@' is wanted.
8302 2002-09-09 Akim Demaille <akim@epita.fr>
8304 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8305 `duplicates', since the algorithm was too naive and could keep
8306 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8307 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8308 Reported by Ralf Corsepius.
8309 * tests/torture.at (Configuring subdirectories): Exercise these
8310 cases.
8312 2002-09-09 Akim Demaille <akim@epita.fr>
8314 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8315 looking for a replacement file.
8316 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8317 directory is relative.
8318 * doc/autoconf.texi (Generic Functions): Clarify the replacement

8322 2002-09-06 Akim Demaille <akim@epita.fr>
8324 * doc/autoconf.texi (Setting Output Variables): Clarify what
8325 precious variables are.
8326 Suggested by Pontus Skoeld.
8328 2002-09-05 Akim Demaille <akim@epita.fr>
8330 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8331 (ifnames, autoscan, autom4te): Since we don't only depend on
8332 configure.ac variables (such as VERSION etc.), but also on prefix
8333 and so forth, depend on Makefile, not configure.ac.
8334 Reported by Alexandre Duret-Lutz.
8335 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8337 2002-09-05 Kevin Ryde <user42@zip.com.au>
8339 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8340 doesn't seem to be confined to ia64, just say "some versions".
8342 2002-09-04 Akim Demaille <akim@epita.fr>
8344 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8345 Automake 1.6c.
8346 * Makefile.am (maintainer-clean-local): Remove.
8347 (MAINTAINERCLEANFILES): Remove COPYING.
8349 2002-09-03 Paul Eggert <eggert@twinsun.com>
8351 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8352 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8353 Brinkmann.
8355 2002-09-03 Akim Demaille <akim@epita.fr>
8357 * configure.ac: Bump to 2.53d.
8358 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8359 as of today, on Automake's team suggestion.
8361 2002-09-03 Akim Demaille <akim@epita.fr>
8363 Version 2.53c.
8365 2002-09-02 Akim Demaille <akim@epita.fr>
8367 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8368 SITE_MACRO_DIR.
8369 * configure.ac: Disable SITE_MACRO_DIR.
8371 2002-09-02 Jim Meyering <meyering@lucent.com>
8373 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8374 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8375 Also, tweak grammar: s/make sure to/be sure to/.
8377 2002-09-02 Paul Eggert <eggert@twinsun.com>
8379 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8380 directory names are generally preferable to physical names.
8382 2002-09-02 Akim Demaille <akim@epita.fr>
8384 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8385 Reported by Raja R. Harinath.
8386 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8387 * bin/autoupdate.in: Use error instead of die.
8389 2002-09-01 Paul Eggert <eggert@twinsun.com>
8391 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8392 ordinary shell concatenation rather than echo+tr+sed command that
8393 runs afoul of a long-line-related sed bug in Solaris 8.
8395 * bin/autoheader.in (parse_args): --warning -> --warnings.
8397 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8398 stdout, as traditional "ls" does.
8399 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8400 _AC_COMPILER_EXEEXT_O): Likewise.
8401 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8403 * bin/autoconf.as: Add --prepend-include option. This patch was
8404 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8405 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8407 * bin/autoconf.in, configure: Regenerate.
8409 * doc/autoconf.texi (Special Shell Variables): Mention
8410 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8412 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8413 MAILPATH and set PS1, PS2, PS4 to default values, to work
8414 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8415 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8416 the Autoconf documentation specifies; fall back to "unset" only if
8417 this fails. Use a shell for-loop for this rather than an m4 loop,
8418 to shorten the output script.
8420 2002-08-30 Paul Eggert <eggert@twinsun.com>
8422 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8423 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8424 for the CDPATH problem. Document PWD.
8425 (Limitations of Builtins): Document the problem that "cd $foo" and
8426 "ls $foo" may refer to different directories in shells conforming
8427 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8428 example, since the old example is now out of date.
8430 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8431 FOO" and "ls FOO" talk about different directories; this catches
8432 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8433 spaghetti.
8435 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8436 of rolling our own unset.
8437 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8438 in practice we needn't worry about CDPATH if unset doesn't work.
8440 * Makefile.in, aclocal.m4, bin/Makefile.in,
8441 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8442 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8443 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8444 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8445 tests/Makefile.in: Regenerate with Automake 1.6.3.
8447 * config/config.guess, config/config.sub, config/mkinstalldirs:
8448 Update.
8450 * configure: Regenerate with self.
8452 2002-08-30 Kevin Ryde <user42@zip.com.au>
8454 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8455 default output.

8459 * bin/autom4te.in (Request::load): Correctly test for "do" read
8460 failure.
8462 2002-08-29 Akim Demaille <akim@epita.fr>
8464 * lib/Autom4te/General.pm (&xqx): New.
8465 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8466 hand, which is not portable.
8467 (&error): New.
8468 * bin/autom4te.in: Use them.
8469 Use &error instead of die.
8470 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8471 Adjust.
8473 2002-08-17 Paul Eggert <eggert@twinsun.com>
8475 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8476 default list of compilers to try, since it was long ago superseded
8477 by the ksh fc builtin. Suggested by Steven G. Johnson.
8479 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8481 * doc/autoconf.texi (Invoking autom4te): End the option table,
8482 fixing a bug introduced by the previous patch.
8483 (Limitations of Make): Add a 'target lookup' subentry in the
8484 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8486 2002-07-29 Mark D. Roth <roth@feep.net>
8488 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8489 options and use $AUTOM4TE_PATH.
8490 * doc/autoconf.texi: Remove documentation of autom4te
8491 --include-envvar and --site-macro-subdir options and document
8492 use of $AUTOM4TE_PATH.
8493 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8494 arguments from each language section.
8496 2002-07-29 Paul Eggert <eggert@twinsun.com>
8498 * doc/install.texi: Include copyright symbol in copyright notice.
8500 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8501 Replace with:
8502 (AM_MAKEINFOFLAGS): New macro.
8503 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8504 * Makefile.am (INSTALL): Use the new macros.
8505 Use -o rather than --output, since "missing" does not grok --output.
8507 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8509 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8510 comments do not always work. Never trust the exit status of
8511 `make -k'.
8513 2002-07-24 Kevin Ryde <user42@zip.com.au>
8515 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8516 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8518 2002-07-23 Paul Eggert <eggert@twinsun.com>
8520 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8521 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8522 apparently treats PATH="nonexistent" as if it contained ".".
8523 Bug reported by Stefan `Sec' Zehl.
8525 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8527 * doc/autoconf.texi (Limitations of Make): Mention the special

8550 * config/config.guess, config/config.sub: Update.

8684 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
8686 * bin/autom4te.in ($cache): Don't define using `$me', the name
8687 of the cache should not depend on the name under which autom4te
8688 was installed.
8690 2002-06-07 Akim Demaille <akim@epita.fr>
8692 * tests/tools.at (autoconf: forbidden tokens, basic)

8764 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
8765 * doc/autoconf.texi (Particular Programs): Document them.
8766 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
8767 * NEWS: Likewise.
8769 2002-05-27 Paul Eggert <eggert@twinsun.com>
8771 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
8772 * NEWS, doc/autoconf.texi (Particular Types): Document it.
8773 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
8774 instead of AC_MBSTATE_T, which never existed.
8776 2002-05-23 Akim Demaille <akim@epita.fr>
8778 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
8779 version of Autoconf that is discussed.
8781 2002-05-22 Paul Eggert <eggert@twinsun.com>
8783 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
8784 from the default list of compilers to try. Suggested by
8785 Kate Hedstrom.
8786 * NEWS: Document the above.
8787 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
8789 2002-05-17 Paul Eggert <eggert@twinsun.com>
8791 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
8792 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
8793 This improves on an earlier suggestion by H. Peter Anvin.
8795 2002-05-16 Paul Eggert <eggert@twinsun.com>
8797 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
8798 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
8799 Both macros now accept an optional source-dir arg.
8800 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
8802 * NEWS: Document this.
8803 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
8805 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
8806 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
8807 not for GNU extensions; this undoes part of the 2000-11-03 change,
8808 reverting to 2.13-compatible behavior.
8809 Add new optional argument DIR.
8810 (AC_FUNC_FNMATCH_GNU): New macro.
8812 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
8814 2002-05-08 Paul Eggert <eggert@twinsun.com>
8816 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
8817 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
8818 and it causes a 'test' syntax error if it fails.
8819 Bug reported by Stephen Gildea.
8821 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
8822 If prototypes are supported, use them to check this at compile-time,
8823 instead of trying to check it at run-time. If we must do a run-time
8824 check, assume that setvbuf is standard when cross-compiling, as
8825 nonstandard setvbuf occurs only on ancient and unlikely hosts.
8826 Bug reported by Paul D. Smith.
8828 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
8829 argument specifying location of getloadavg.c. This removes a
8830 FIXME. This idea was taken from Jim Meyering's implementation in
8831 textutils.
8832 * doc/autoconf.texi (Particular Functions): Document this.
8833 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
8834 that's what the code does; this fixes a bug reported by
8835 Paul D. Smith.
8837 2002-05-03 Akim Demaille <akim@epita.fr>
8839 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
8840 autopoint instead of gettextize.
8841 ($uses_alocal): Rename as...
8842 ($uses_aclocal): this.
8843 * doc/autoconf.texi (autoreconf Invocation): Adjust.
8844 Suggested by Bruno Haible.
8846 2002-05-03 Akim Demaille <akim@epita.fr>
8848 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
8850 2002-04-29 Paul Eggert <eggert@twinsun.com>
8852 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
8853 files to be 1 second older; just set them to be the same time.
8854 Also, sleep 1 second after the first aclocal, to work around
8855 problems with sub-second time stamps on the input files.
8857 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
8859 * doc/autoconf.texi: Mention "set -e -x" lossage
8860 under node "Limitations of Builtins".
8862 2002-04-29 Akim Demaille <akim@epita.fr>
8864 * doc/install.texi: Better wording for setting variables when
8865 running configure.
8866 From Christian Cornelssen.
8868 2002-04-29 Akim Demaille <akim@epita.fr>
8870 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
8871 of lack of $LINENO support, then the test will compare the $LINENO
8872 in testsuite vs. the lineno in the test file. This is wrong, of
8873 course.
8874 Be sure to protect it.
8875 Reported by Patrick Welche.
8877 2002-04-25 Akim Demaille <akim@epita.fr>
8879 * doc/autoconf.texi (Obsolete Macros): Typo.
8880 Reported by Vladimir Volovich.
8882 2002-04-25 Akim Demaille <akim@epita.fr>
8884 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
8885 than some of the input files, hence, on the second run of aclocal,
8886 if some of its input are younger, make them older.
8887 Suggested by Paul Eggert.
8889 2002-04-25 Akim Demaille <akim@epita.fr>
8891 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
8892 Thanks to Paul Eggert.
8894 2002-04-25 Akim Demaille <akim@epita.fr>
8896 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
8897 and ac_subst_vars be sh variables containing the list of
8898 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
8899 DEFAULT diversion.
8900 (_AC_INIT_PREPARE): Use them to log them.
8901 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
8902 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
8903 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
8904 _AC_SUBST_FILES and _AC_SUBST_VARS.
8905 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
8907 2002-04-24 Akim Demaille <akim@epita.fr>
8909 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
8910 autoheader, so that automake does not complain about a missing
8911 config.h.in that was to be created.
8913 2002-04-23 Akim Demaille <akim@epita.fr>
8915 * bin/autoheader.in (parse_args): --warning takes an argument.
8916 Fixes PR/220.
8918 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
8920 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
8921 and bb.out when cleaning up.
8923 2002-04-22 Akim Demaille <akim@epita.fr>
8925 Version 2.53a.
8927 2002-04-22 Akim Demaille <akim@epita.fr>
8929 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
8931 2002-04-22 Akim Demaille <akim@epita.fr>
8933 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
8934 comma.
8935 Reported by Gregory Giannoni.
8937 2002-04-22 Akim Demaille <akim@epita.fr>
8939 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
8940 Fixes false failures on Darwin.
8942 2002-04-21 Paul Eggert <eggert@twinsun.com>

8946 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

8965 Minor spelling and grammar fixes.
8967 * doc/autoconf.texi: Follow the outline suggested in the GNU
8968 Sample Texts sections of the Texinfo 4.2 manual. Most
8969 importantly, this makes sure that the copyright notices appear in
8970 all output formats. You probably need Texinfo 4.2 to generate
8971 the manual now.
8973 Fix some bugs when using "$@" when there might be zero positional
8974 arguments in cases where this matters.

8995 that is not portable to Zsh.
8997 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
8999 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9000 from aclocal.m4 too.
9002 2002-04-12 Akim Demaille <akim@epita.fr>
9004 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9006 2002-04-10 Akim Demaille <akim@epita.fr>
9008 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9009 workaround for ${1+"$@"}.
9010 * doc/autoconf.texi (Shell Substitutions): Explain it.
9011 From Oliver Kiddle and Peter Stephenson.
9013 Have M4sh perform minimal shell sanitizing.
9015 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9016 part into...
9017 (_AS_PREPARE): this new macro.
9018 (AS_PREPARE): New.
9019 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9020 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9022 Adjust Autoconf and Autotest.
9024 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9025 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9026 * lib/autotest/general.m4 (AT_INIT): Likewise.
9027 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9028 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9029 AS_SHELL_SANITIZE.
9031 Use this M4sh to generate Autoconf's shell scripts.
9033 * tests/wrapsh.as: New, precursor of wrapsh.in.
9034 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9035 on Autotest and M4sh.
9036 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9037 (wrapsh.in): New target.
9038 * bin/autoconf.as: New, precursor of autoconf.in.
9039 (autoconf.in): New target.

9044 with indented comments in rules.
9046 2002-04-09 Andreas Schwab <schwab@suse.de>
9048 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9049 ac_top_builddir when setting ac_abs_top_builddir.
9051 2002-04-06 Kevin Ryde <user42@zip.com.au>
9053 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9054 (Portable Shell): Cross reference to Systemology.
9056 2002-04-05 Akim Demaille <akim@epita.fr>
9058 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9059 directories when descending in a SUBDIRS.
9060 Reported by Ezra Peisach.
9062 2002-04-04 Andreas Schwab <schwab@suse.de>
9064 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9065 contains no literal separators.
9067 2002-04-03 Akim Demaille <akim@epita.fr>
9069 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9070 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9071 Use dnl, not the KILL diversion.
9072 Extracted from...
9073 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9074 (AC_CONFIG_LINKS): here.
9075 Adjust.
9076 Don't use the KILL diversion, as it kills spurious output, which
9077 results in failures being hidden.
9078 Use m4_defn where appropriate.
9079 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9080 after the second argument.
9081 Use m4_defn.
9082 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9083 syntax, as it is provided by M4sugar.
9084 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9086 2002-04-03 Andreas Schwab <schwab@suse.de>
9088 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9089 expanded if $# <= 2.

9092 aclocal.
9094 2002-04-03 Akim Demaille <akim@epita.fr>

9098 Also recognize *.bb and *.bbg as compilation byproducts.
9099 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9100 (_AC_COMPILER_OBJEXT): Use them.
9101 Fixes Debian #138666.
9103 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9105 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9107 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9108 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9109 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9110 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9111 (AC_C_CONST): Same.
9112 (AC_C_INLINE): Same.
9113 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
9114 * doc/autoconf.texi, NEWS: Document.
9115 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9116 AC_C_CROSS.

9120 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
9121 _AS_MKDIR_P_PREPARE.
9123 2002-03-28 Kevin Ryde <user42@zip.com.au>
9125 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9126 to avoid versions of HP C which don't allow that.
9128 2002-03-27 Paul Eggert <eggert@twinsun.com>
9130 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9131 (AS_SHELL_SANITIZE): Invoke it.
9132 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.

9142 2002-03-25 Paul Eggert <eggert@twinsun.com>
9144 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9145 as POSIX requires, as it doesn't work with Zsh.
9146 * doc/autoconf.texi (Assignments): Document the problem.
9148 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9150 * doc/autoconf.texi (Limitations of Make): Mention more issue
9151 about VPATH, overriding of macros in sub-makes, and handling of
9152 SHELL.
9154 2002-03-21 Paul Eggert <eggert@twinsun.com>
9156 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9157 problem with here-document buffer boundaries.
9159 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9160 when reinvoking the shell, to work around problems with installers
9161 who put strange things like "cd" commands in their environments.
9163 2002-03-19 Akim Demaille <akim@epita.fr>
9165 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9166 From Aaron Ucko.
9168 2002-03-19 Akim Demaille <akim@epita.fr>
9170 * bin/autoscan.in (scan_file): Specify the location in `&used'
9171 invocations.
9172 From Nicolas Joly.
9174 2002-03-19 Akim Demaille <akim@epita.fr>
9176 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9177 From Nishio Futoshi.
9179 2002-03-19 Akim Demaille <akim@epita.fr>
9181 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9183 2002-03-18 Paul Eggert <eggert@twinsun.com>
9185 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9186 (Limitations of Usual Tools): Add mkdir section.
9188 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9189 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9190 back on AS_DIRNAME to compute prefixes otherwise; this is
9191 roughly what mkinstalldirs does. That way, we need not have
9192 our own filename disassembler. The old disassembler did not
9193 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9195 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9196 Create at_test_all by a series of assignments,
9197 not by a single assignment of a long string. The latter causes ksh
9198 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9199 presumably because of a buffer overrun.
9201 2002-03-14 Paul Eggert <eggert@twinsun.com>
9203 * lib/autotest/general.m4 (at_times_skip):
9204 Renamed from at_times. Now a boolean.
9205 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9206 says 'times: not found'.
9208 2002-03-14 Akim Demaille <akim@epita.fr>
9210 * bin/autoreconf.in (&study_gettextize): New.
9211 (&autoreconf): Handle newest gettextize.
9212 Rerun aclocal if needed.
9213 Suggested by Andreas Schwab.
9215 2002-03-13 Akim Demaille <akim@epita.fr>
9217 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9219 2002-03-13 Akim Demaille <akim@epita.fr>
9221 * doc/autoconf.texi (Header Portability): New.
9222 Add information about stdint.h and inttypes.h from Paul Eggert.
9224 2002-03-13 Akim Demaille <akim@epita.fr>
9226 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9227 -p'.
9228 From Bob Proulx.
9230 2002-03-12 Akim Demaille <akim@epita.fr>
9232 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9233 m4_require.
9235 2002-03-11 Andreas Schwab <schwab@suse.de>
9237 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9238 does not do it if --with-lispdir is given.
9240 2002-03-08 Akim Demaille <akim@epita.fr>
9242 Version 2.53.
9244 2002-03-08 Akim Demaille <akim@epita.fr>
9246 * doc/autoconf.texi (Subdirectories): Clarify that the
9247 subdirectory should exist.
9249 2002-03-08 Akim Demaille <akim@epita.fr>
9251 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9253 2002-03-08 Akim Demaille <akim@epita.fr>
9255 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9256 aliases the actual variables, and modifications of the former
9257 affect the latter.
9259 2002-03-08 Akim Demaille <akim@epita.fr>
9261 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9262 because of C-c: have m4 output in tmp files, then mv them.
9264 2002-03-08 Akim Demaille <akim@epita.fr>
9266 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,

9274 2002-03-05 Akim Demaille <akim@epita.fr>
9276 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9277 Kevin Ryde.

9289 2002-03-04 Akim Demaille <akim@epita.fr>
9291 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9292 parallel builds.
9294 2002-03-04 Akim Demaille <akim@epita.fr>
9296 * doc/autoconf.texi (Transforming Names): Equality between target
9297 and host is irrelevant.
9298 (Specifying Names, Canonicalizing): Remove all references to the
9299 backward compatibility hooks. Rather, collect them all into...
9300 (Hosts and Cross-Compilation): this new section.
9301 * doc/install.texi (System Type): Ditto.
9302 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9303 that `--host' implies cross-compilation.
9305 2002-03-04 Akim Demaille <akim@epita.fr>
9307 * doc/autoconf.texi (Evaluation Macros): New.
9308 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9309 useless.
9310 (_m4_foreach): Define the variant with immediate evaluation so
9311 that it contains exactly the items, not an expression which
9312 evaluation is the current item.
9313 (m4_re_string, m4_re_word): Don't over quote them.
9315 2002-03-04 Akim Demaille <akim@epita.fr>
9317 Instead of having stacking `shift's evaluated at the end, let
9318 `foreach' loops immediately evaluate them.
9320 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9321 $*. This is the n-th time I change my mind, but hopefully this is
9322 the last...
9323 (m4_lquote): New.
9324 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9325 efficient.
9326 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9327 it was only a hack for m4_text_wrap.
9328 (m4_car2): Remove, replaced by...
9329 (m4_cdr): New.
9330 (_m4_foreach): Adjust.
9331 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9332 m4_bpatsubst for clarification.
9334 2002-03-04 Akim Demaille <akim@epita.fr>
9336 * doc/autoconf.texi (Changequote is Evil): New.
9338 2002-03-03 Kevin Ryde <user42@zip.com.au>

9360 2002-02-25 Akim Demaille <akim@epita.fr>
9362 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9363 From Akinori Musha.
9365 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9367 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9368 translate \r\n to \n.
9370 2002-02-07 Akim Demaille <akim@epita.fr>
9372 Version 2.52h.

9381 2002-02-07 Akim Demaille <akim@epita.fr>
9383 Fix Autoconf PR/207:
9384 AC_PREFIX_PROGRAM fails with dashed program names
9386 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9387 variable when looking for the prefix program.
9388 Now it also works for shell variables.
9390 2002-02-07 Akim Demaille <akim@epita.fr>
9392 * doc/autoconf.texi (Limitations of Builtins): More about
9393 case/esac.
9395 2002-02-06 Akim Demaille <akim@epita.fr>
9397 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9398 case/esac, some shells don't support it.
9399 Reported by Zack Weinberg.
9400 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9402 2002-02-06 Akim Demaille <akim@epita.fr>
9404 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9405 sure not to introduce newlines in at_groups.
9406 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9408 2002-02-06 Akim Demaille <akim@epita.fr>
9410 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9411 is not available.
9413 2002-02-05 Paul Eggert <eggert@twinsun.com>
9415 * doc/autoconf.texi (Specific Compiler Characteristics):
9416 Describe HP-UX cc bug workaround more accurately.
9417 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9418 not unsigned long.
9419 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9420 cross-compilers, too. This undoes some of the most recent change
9421 to this file.
9423 2002-02-05 Akim Demaille <akim@epita.fr>
9425 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9426 to make sure they are up to date when `check' is run.
9428 2002-02-05 Akim Demaille <akim@epita.fr>
9430 * doc/autoconf.texi (Making testsuite Scripts): Document
9431 package.m4.
9433 2002-02-05 Akim Demaille <akim@epita.fr>
9435 * lib/freeze.mk: New.
9437 2002-02-05 Akim Demaille <akim@epita.fr>
9439 Implement `autom4te --freeze'.
9441 * bin/autom4te.in (&freeze): New.
9442 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9443 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9445 2002-02-05 Akim Demaille <akim@epita.fr>
9447 * bin/autom4te.in (&parse_args): Implement `frozen files are
9448 optional are the sum of the previous files on the command line'.
9449 Also, pass `--reload-state=' on them, so...
9450 (handle_m4): don't.
9451 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9452 (M4sh): Rely on M4sugar.
9453 (Autotest, M4sh, M4sugar): Use frozen files.
9455 2002-01-31 Akim Demaille <akim@epita.fr>
9457 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9458 * doc/autoconf.texi (Initializing configure): Adjust.
9460 2002-01-30 Akim Demaille <akim@epita.fr>
9462 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9463 alphanumeric to `-' instead of `_'.
9465 2002-01-30 Akim Demaille <akim@epita.fr>
9467 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9468 for plain code, the other for cross-compilation code. The latter
9469 is now run with GCC only.
9470 * doc/autoconf.texi (Compilers and Preprocessors): New.
9472 2002-01-30 Akim Demaille <akim@epita.fr>
9474 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9475 values.
9476 * doc/autoconf.texi (Initializing configure): Explain how to
9477 change AC_INIT default values.
9479 2002-01-29 Akim Demaille <akim@epita.fr>
9481 * tests/torture.at (Configuring subdirectories): Use configure.in,
9482 so that aclocal 1.4 works.
9483 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9485 2002-01-28 Akim Demaille <akim@epita.fr>
9487 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9488 needs an argument.
9490 2002-01-28 Akim Demaille <akim@epita.fr>
9492 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9493 AUTOTEST_PATH *after* it was set.
9494 Don't put `.' in the PATH: the user should be precise and `./' if
9495 needed. In addition, given that the test suite does some `cd', if
9496 `.' is in the path, the `tested programs' sections will report
9497 programs found in the test suite's directory, while during the
9498 tests (performed in their own directory), these programs are no
9499 longer visible. In other words, the results is confusing and
9500 useless.
9501 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9503 2002-01-24 Akim Demaille <akim@epita.fr>
9505 Version 2.52g.
9507 2002-01-24 Akim Demaille <akim@epita.fr>
9509 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
9510 * doc/autoconf.texi: Finally add Akim as an author.
9512 2002-01-24 Akim Demaille <akim@epita.fr>
9514 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9515 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9516 Bourne. Use /bin/sh.
9517 From Andreas Buening.
9519 2002-01-24 Akim Demaille <akim@epita.fr>
9521 * config/config.guess, config/config.sub, config/texinfo.tex:
9522 Update from masters.
9524 2002-01-24 Akim Demaille <akim@epita.fr>
9526 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.

9530 * config/strip.m4: Remove, to ease sync'ing with any version of
9531 Automake.

9535 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9536 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9537 Reported by Geir Ove Myhr.
9539 2002-01-21 Akim Demaille <akim@epita.fr>
9541 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9543 2002-01-21 Akim Demaille <akim@epita.fr>
9545 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9546 message on invalid options.
9547 * bin/autom4te.in (parse_args): Don't use
9548 Autoconf::General::getopt with non valid options.
9550 2002-01-17 Jim Meyering <meyering@lucent.com>
9552 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9553 $ac_cv_exeext so we don't use an old, invalid, cached value.
9555 2002-01-11 Akim Demaille <akim@epita.fr>
9557 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9558 Meyering.

9564 2002-01-06 Akim Demaille <akim@epita.fr>
9566 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9567 package.m4, since is really depends upon configure.ac, not
9568 configure.
9569 * doc/autoconf.texi (testsuite Scripts): Adjust.
9570 * tests/Makefile.am (package.m4): New.
9571 EXTRA_DIST it since its a source.
9573 2002-01-06 Akim Demaille <akim@epita.fr>
9575 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9576 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9577 and PACKAGE_BUGREPORT from here...
9578 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9579 arguments.
9580 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9581 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9582 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9583 * tests/tools.at (autoheader): Adjust.
9584 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9586 2002-01-06 Akim Demaille <akim@epita.fr>
9588 * bin/autoscan.in (scan_file): Use `&used'.
9590 2002-01-03 Akim Demaille <akim@epita.fr>
9592 * doc/autoconf.texi (Output): Improved wording regarding use of
9593 AC_OUTPUT.

9598 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9599 sometimes needing writable input.
9601 2001-12-17 Jim Meyering <meyering@lucent.com>
9603 * doc/autoconf.texi (New Macros): Tweak wording.
9605 2001-12-14 Akim Demaille <akim@epita.fr>
9607 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9608 trailing files, don't apply `-rf' to files which might not be
9609 created by configure (core, core.*, and *.core), but just `rm -f'.
9610 Suggested by Jonathan Kamens.
9612 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9614 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9616 2001-12-14 Akim Demaille <akim@epita.fr>
9618 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9620 2001-12-13 Peter Eisentraut <peter_e@gmx.net>

9623 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9624 abs_srcdir, top_srcpath to abs_top_srcdir.

9630 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

9633 C/Fortran linking on HP/UX, by extracting the Fortran library
9634 search path from the LPATH line in the $F77 -v output.
9636 2001-12-12 Kevin Ryde <user42@zip.com.au>
9638 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
9639 forbidden file descriptors table.
9641 2001-11-26 Akim Demaille <akim@epita.fr>
9643 * bin/autoscan.in (%c_keywords): Build it at top level.
9644 Map to 1 in order to simplify its uses.
9646 2001-11-26 Akim Demaille <akim@epita.fr>
9648 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
9649 Remove $filepath, useless.
9650 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
9651 variables, they are really part of the tokens.
9652 Split the input line on spaces and then look for tokens.
9653 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
9654 because of `lex$U.$(OBJEXT)'.
9655 (&scan_files): Use "@list" instead of join.
9656 * doc/Makefile.am (CLEANFILES): Add *.fns.
9658 2001-11-26 Akim Demaille <akim@epita.fr>
9660 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
9661 Remove, replaced by...
9662 * tests/wrappl.in: Be common for all the Perl executables.
9663 In particular autoscan and autoheader want -I.
9664 * configure.ac: Adjust.
9665 * lib/autoscan/headers: errno.h is portable.
9667 2001-11-26 Akim Demaille <akim@epita.fr>
9669 * bin/autoscan.in (used): New.
9670 Use it.
9672 2001-11-26 Akim Demaille <akim@epita.fr>
9674 * bin/autoscan.in (&scan_c_file): Better parsing of CPP

9683 Before, having a line containing the opening of a multi line
9684 comment made the whole line be ignored.
9686 2001-11-26 Akim Demaille <akim@epita.fr>
9688 * doc/autoconf.texi (Using an Autotest Test Suite): New.
9689 (testsuite Scripts): Be one of its subsection.
9690 (Autotest Logs): New.
9692 2001-11-26 Akim Demaille <akim@epita.fr>
9694 Test groups are now run two directories deeper.
9696 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
9697 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
9698 at_top_builddir.
9699 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
9700 top_srcdir, builddir and top_builddir.
9701 Use `at_*dir' relatively to the directory containing the
9702 suite, use `*dir' when relatively to the current group dir.
9704 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
9706 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
9707 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
9708 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
9709 spelling errors.
9711 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
9713 * doc/autoconf.texi (Using System Type): Add an example of `case
9714 $host' usage so people quit using `case $target' everywhere.
9716 2001-11-22 Akim Demaille <akim@epita.fr>
9718 * doc/autoconf.texi (Installation Directory Variables): Englishoes
9719 spotted by Jim Meyering.
9721 2001-11-16 Paul Eggert <eggert@twinsun.com>
9723 This patch implements a `long double' suggestion by Oliver Kiddle.
9725 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
9726 static, to catch errors if the value isn't known at compile-time
9727 and the compiler supports dynamic arrays. Change its name from
9728 `_array_' to `test_array' to avoid potential name clashes.
9729 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
9730 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
9731 better than double. Catch a bug in GCC 2.95.2 x86.
9732 * doc/autoconf.texi (C Compiler): Document the above.
9733 * NEWS: Likewise.
9735 2001-11-13 Akim Demaille <akim@epita.fr>
9737 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
9738 hand.
9739 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
9741 2001-11-13 Akim Demaille <akim@epita.fr>
9743 * lib/autotest/general.m4 (AT_INIT): After having run the test
9744 group, go back to the initial directory, not to at_suite_dir.
9746 2001-11-13 Akim Demaille <akim@epita.fr>
9748 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
9749 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
9750 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
9751 option.
9752 (AT_CHECK_CONFIGURE): Use absolute paths.
9753 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
9754 The problem is still the old one: there is no means in M4 (that I
9755 know about) to create a defining macro, because there is no means
9756 to create `$1' etc., therefore, the defining macro ``swallows''
9757 all the arguments meant to the defined macro.
9759 2001-11-13 Akim Demaille <akim@epita.fr>
9761 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
9762 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
9763 configure.ac.
9764 * tests/aclocal.m4: Remove, as it is no longer used.
9766 2001-11-13 Akim Demaille <akim@epita.fr>
9768 * lib/autotest/general.m4: Change `tests?' into `groups?' in
9769 variable names when referring to a single test group, or to
9770 `suite' when referring to the whole test suite.
9771 `at_last_test' is removed: m4 compute at_format itself.
9772 (at_stdout, at_stder1, at_stderr): New variables.
9773 (AT_CHECK): Use them.
9775 2001-11-13 Akim Demaille <akim@epita.fr>
9777 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
9778 in PATH.
9779 Create `testsuite.dir/003/run' instead of `testsuite.003'.
9780 Do it as soon as a test fails, don't wait till the end of the test
9781 suite.
9782 Don't remove $as_me.[0-9]*, since these files no longer exist.
9784 2001-11-13 Akim Demaille <akim@epita.fr>
9786 * tests/tools.at: Use absolute paths, since we are no longer run
9787 in place.
9789 2001-11-13 Akim Demaille <akim@epita.fr>
9791 Now that tests are running in their own private dir, there is no
9792 need to list the files to remove at the end of tests groups.
9794 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
9795 (AT_data_files, at_data_files): Remove.
9796 (AT_CLEANUP, AT_DATA): Simplify.
9797 (AT_INIT): Adjust.
9798 Remove the group dir if !debug && !failed.
9799 * tests/atspecific.m4: Adjust.
9801 2001-11-13 Akim Demaille <akim@epita.fr>
9803 Start a new layout for Autotest: `testsuite' creates
9804 `testsuite.dir' in which the at-check-line etc. files are to be
9805 found, and `testsuite.dir/003' where the test group 3 is run.
9807 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
9808 at_check_line_file, at_format, at_test_normalized, at_group_dir
9809 are new variables.
9810 Create the directories.
9811 Use absolute paths for at- files.
9812 (AT_CHECK): Adjust.
9814 2001-11-11 Michael Matz <matz@kde.org>
9816 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
9817 (m4_car2): New.
9818 (m4_car): Properly quote arguments.
9820 2001-11-13 Akim Demaille <akim@epita.fr>
9822 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
9823 with stricter rules on LIBOBJS.
9825 2001-11-12 Paul Eggert <eggert@twinsun.com>
9827 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
9828 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
9829 __PROTOTYPES too.
9831 2001-11-12 Akim Demaille <akim@epita.fr>
9833 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
9835 2001-11-12 Akim Demaille <akim@epita.fr>
9837 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
9838 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
9839 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
9840 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
9841 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
9842 specify to what the macro should be defined (typically to 1).
9844 2001-11-12 Akim Demaille <akim@epita.fr>
9846 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
9847 From Jim Meyering.
9849 2001-11-12 Akim Demaille <akim@epita.fr>
9851 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
9852 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
9853 definition used by Automake where LEX is +/- "${missing} lex" and
9854 `missing' itself contains variables.
9856 2001-11-12 Akim Demaille <akim@epita.fr>
9858 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
9859 Now that M4sh pushes BODY, the comments were output at the end of
9860 the test suites.
9862 2001-11-08 Akim Demaille <akim@epita.fr>
9864 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
9865 that we can trace macros from aclocal.m4.
9866 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
9867 obsoleted, and redirect to the former anyway.
9868 Reported by Ralf Corsepius.
9870 2001-11-08 Akim Demaille <akim@epita.fr>
9872 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
9873 processed only if present.
9874 * tests/torture.at (Configuring subdirectories): Use autoreconf
9875 instead of successive calls to autoconf.
9876 Add a nonexistent subdirectory to exercise the patch above.
9877 Reported by Ralf Corsepius.
9879 2001-11-08 Kevin Ryde <user42@zip.com.au>
9881 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
9882 doesn't accept .S files.
9884 2001-11-07 Akim Demaille <akim@epita.fr>
9886 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
9887 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
9888 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
9889 * bin/autom4te.in (warn_forbidden): New.
9890 (handle_output): Use it.
9891 Read m4_pattern_forbid with messages.
9893 2001-11-05 Akim Demaille <akim@epita.fr>
9895 * bin/autom4te.in (--normalize): Remove.
9896 * lib/autom4te.in: Adjust.
9898 2001-11-05 Akim Demaille <akim@epita.fr>
9900 * tests/Makefile.am (testsuite): Rename this target as...
9901 ($(TESTSUITE)): this.
9902 From Nicolas Joly.
9904 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
9906 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
9907 the --prefix option, also remove it's argument.
9909 2001-11-05 Akim Demaille <akim@epita.fr>
9911 * doc/autoconf.texi (testsuite Invocation): Update.
9912 (Writing testsuite.at): Update.
9914 2001-11-03 Akim Demaille <akim@epita.fr>
9916 * doc/autoconf.texi: s/@code/@command/ where appropriate.
9918 2001-11-03 Akim Demaille <akim@epita.fr>
9920 * lib/Autom4te/General.pm: (&catfile, &canonfile)
9921 (&file_name_is_absolute): New, wrappers around routines from
9922 File::Spec.
9923 Use and export them.
9924 (&find_configure_ac): Optionally take a directory where to look at.
9925 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
9926 the arguments.
9927 Default @ARGV to `.', not find_configure_ac.
9928 (&autoreconf): Argument is a directory.
9929 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
9930 * doc/autoconf.texi (autoreconf Invocation): Update.
9932 2001-11-03 Akim Demaille <akim@epita.fr>
9934 * lib/Autom4te/General.pm (@export_vars, @export_subs)
9935 (@export_forward_subs): New.
9936 Add basename, dirname, and fileparse.
9937 (@EXPORT): Adjust.
9938 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
9939 Don't look for aclocal flags if we already know aclocal is not
9940 used.
9941 Move aclocal.m4t only if it exists.
9942 Reported by Ezra Peisach.
9944 2001-11-03 Akim Demaille <akim@epita.fr>
9946 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
9947 passed on command line, defaulting to ./configure.ac if present.
9948 (&maybe_autoreconf, File::Find): Remove, unused.
9949 (&autoreconf): If autoconf is not used, don't try to trace.
9951 2001-11-02 Akim Demaille <akim@epita.fr>
9953 * configure.ac: Bump to 2.52g.
9955 2001-11-02 Akim Demaille <akim@epita.fr>
9957 Version 2.52f.
9959 2001-11-02 Akim Demaille <akim@epita.fr>
9961 * config/config.guess, config/config.sub, doc/standards.texi:
9962 * config/lispdir.m4: Update from masters.
9963 * configure.ac: Bump to 2.52f.
9965 2001-11-02 Akim Demaille <akim@epita.fr>
9967 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
9968 Don't run aclocal when aclocal.m4 is not from aclocal.
9969 From Ezra Peisach.
9970 Don't run libtoolize and gettextize if --install is not given.
9972 2001-11-01 Paul Eggert <eggert@twinsun.com>
9974 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
9975 be invoked before _AS_LINENO_PREPARE.
9976 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
9977 than character ranges.
9979 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
9980 invoking AS_BASENAME. Set the locale variables to 'C' if
9981 possible, as POSIX requires this to get the traditional
9982 behavior.
9983 * doc/autoconf.texi (Special Shell Variables): Describe the above.
9985 2001-10-31 Paul Eggert <eggert@twinsun.com>
9987 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
9988 with {}, as that triggers a bug in Bash 2.05.
9990 (_AS_LINENO_PREPARE): Use Sed rather than
9991 Awk. Fix the sed prepass to work even if there are multiple
9992 instances of $LINENO on the same line. Do not substitute for
9993 other variables like $LINENOT. Do not check file dates; such a
9994 check is unreliable on sufficiently fast machines, and removing
9995 the check makes the code simpler and more reliable. Check for
9996 output and chmod failures.
9998 * doc/autoconf.texi (Special Shell Variables): Document
9999 the above.
10001 2001-10-31 Akim Demaille <akim@epita.fr>
10003 * tests/Makefile.am (atconfig): Remove this target, Automake
10004 handles it now.
10006 2001-10-31 Akim Demaille <akim@epita.fr>
10008 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10009 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10010 provided, while it is optional.
10011 * configure.ac: Adjust.
10013 2001-10-26 Paul Eggert <eggert@twinsun.com>
10015 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10016 lib/Autom4te/Struct.pm:
10017 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10018 with 5.005_02.
10020 * doc/autoconf.texi (Special Shell Variables): Document some
10021 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10023 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10024 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10025 eval $LINENO is not portable in practice.
10027 2001-10-24 Akim Demaille <akim@epita.fr>
10029 * lib/Autom4te/General.pm (backname): New.
10031 2001-10-24 Akim Demaille <akim@epita.fr>
10033 * m4/: Remove, merged into...
10034 * config/: here.
10036 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10038 * doc/autoconf.texi (Shellology): Mention the problems with bash
10039 2.05's use of ANSI quoting in its `set' builtin.
10041 2001-10-22 Paul Eggert <eggert@twinsun.com>
10043 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10044 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10045 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10046 POSIX decided to standardize on the int flavor of strerror_r.
10047 Always do char* test, as there's no reason not to.
10048 Assign to a char* var, to catch strerror_r that returns int*.
10050 * doc/autoconf.texi (Particular Functions):
10051 Document the above changes. Also, document the fact that
10052 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10054 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10056 2001-10-20 Akim Demaille <akim@epita.fr>
10058 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10059 the executable was missing from the log.
10061 2001-10-20 Akim Demaille <akim@epita.fr>
10063 * lib/Autom4te/General.pm (&update_file): If destination is
10064 unchanged, remove the source.
10065 (&up_to_date_p): Don't be verbose, be debug.
10066 * bin/autoreconf.in: No longer support --m4dir.
10067 (&autoreconf): Display the full path of the configure.ac we are
10068 studying.
10069 Trace it only once.
10070 Be sure to honor --force with gettextize.
10071 Always run aclocal.
10072 * doc/autoconf.texi: Adjust.
10074 2001-10-20 Akim Demaille <akim@epita.fr>
10076 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10077 Remove, dead.
10078 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10079 `intl' is already present, as it refuses unless --force.
10080 (&parse_args): Use -I, --include instead of the old Autoconf
10081 options.
10082 ($localdir, $autoconf_dir): Remove.
10083 (@include): New.
10084 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10086 2001-10-19 Jens Petersen <petersen@redhat.com>

10094 file in @configure_input@.
10095 Don't mention `automatically' in addition to `generated'.
10096 * tests/torture.at (#define header templates): Adjust.
10098 2001-10-19 Akim Demaille <akim@epita.fr>
10100 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10101 comment, explain how to install automatic mode selection.
10102 From Russ Allbery.
10104 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10106 * bin/autoreconf.in (autoreconf): Display the path to the
10107 configure.ac being studied.
10109 2001-10-18 Paul Eggert <eggert@twinsun.com>
10111 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10112 long, to work around a bug in the HP C compiler version HP92453-01
10113 B.11.11.23709.GP.
10115 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10116 (AS_BASENAME_EXPR): New macro.
10117 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10118 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10119 and fall back on 'sed' only if the other two fail. This makes
10120 AS_BASENAME act more like AS_DIRNAME.
10121 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10122 contains white space.
10123 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10124 Use AS_DIRNAME, since I think it's now DOS-friendly.
10125 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10126 Allow "dirname //FOO" to return either / or //, as POSIX allows
10127 either behavior.
10129 2001-10-10 Akim Demaille <akim@epita.fr>
10131 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
10132 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
10133 From Eric Sharkey.

10137 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10138 m4_define, since...

10158 (&parse_args): Pass verbosity/debugging options to subtools when
10159 --debug, not when --verbose.
10160 * lib/autom4te.in (Autoreconf-preselections): New.
10161 (Autoconf): Use it.

10175 (Syntax of the shell scripts): Don't.

10177 bother with $force since...
10178 * lib/Autom4te/General.pm: does.
10180 2001-10-08 Akim Demaille <akim@epita.fr>

10229 (AC_REQUIRE, AC_PROVIDE, AC_PROVIDE_IFELSE): Be exact copy of the
10230 M4sugar peer, i.e., drop the `AC_PROVIDE_$1' broken marker.
10232 2001-10-08 Akim Demaille <akim@epita.fr>
10234 Use `add-log-current-defun-function' for ChangeLog creation.
10235 Suggested by Tom Tromey.
10237 * lib/emacs/autotest-mode.el (autotest-mode-map): New.
10238 (autotest-mode): Adjust.
10239 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

10241 Comments are `#', not `dnl'.
10242 (autoconf-current-defun): New.
10243 (autoconf-font-lock-keywords): Recognize `m4_defun'.
10245 2001-10-08 Akim Demaille <akim@epita.fr>
10247 * lib/autoconf/general.m4 (_m4_divert(BODY)): Move to...
10248 * lib/m4sugar/m4sh.m4: here.
10249 (AS_INIT): Push the BODY diversion, set the #! /bin/sh line.
10250 * lib/autoconf/general.m4 (AC_PLAIN_SCRIPT) : Remove.
10251 (AT_INIT): Replace AC_PLAIN_SCRIPT with AS_INIT invocation,
10252 include handle the m4_pattern_*, no longer push the
10253 BODY diversion nor set the /bin/sh line, AS_INIT does it.
10254 * lib/autotest/general.m4 (AT_INIT): Likewise.
10255 * tests/base.at: Adjust the tests to use AS_INIT.
10256 * tests/tools.at (AT_DATA_FORBIDDEN): New.

10262 * doc/autoconf.texi (config.status Invocation):
10263 CONFIG_SHELL defaults to a shell that supports LINENO if available.

10266 shell does not support LINENO, and if CONFIG_SHELL is unset or
10267 empty, and if we can find a shell that does support LINENO,
10268 then set CONFIG_SHELL to that shell and then re-execute
10269 ourselves with CONFIG_SHELL.
10271 2001-10-05 Paul Eggert <eggert@twinsun.com>
10273 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
10274 doesn't exist. Remove *.tmp, as a .tmp file is created during the
10275 build of $(TESTSUITE).
10277 2001-10-05 Akim Demaille <akim@epita.fr>
10279 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

10288 Fix the absolute path case/esac pattern.
10289 Provide $0 as fallback for as_myself.

10297 2001-10-05 Akim Demaille <akim@epita.fr>
10299 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): New, extracted from...
10300 (AS_SHELL_SANITIZE): here. Use it.
10301 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
10302 From Paul Eggert.
10304 2001-10-04 Akim Demaille <akim@epita.fr>
10306 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
10307 combination of Awk and sed to replace $LINENO.
10309 2001-10-02 Paul Eggert <eggert@twinsun.com>
10311 * doc/autoconf.texi (Limitations of Builtins): You can't use
10312 "source"; it's not portable. Remove confusing and
10313 somewhat-incorrect example involving "." and "/".
10315 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
10316 compatibility with POSIX shells.
10318 2001-10-02 Akim Demaille <akim@epita.fr>
10320 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
10321 instead of exec'ing to preserve $0 and $@.
10323 2001-10-01 Akim Demaille <akim@epita.fr>
10325 * tests/testsuite (AT_INIT) <at_pass_list>: New.
10326 Don't run twice the same test.
10328 2001-10-01 Akim Demaille <akim@epita.fr>
10330 * lib/autotest/general.m4 (AT_INIT) <--help>: Catch up with reality.
10331 No longer output the list of tests.
10332 <--list>: New option.

10335 Various small adjustments.
10337 2001-10-01 Akim Demaille <akim@epita.fr>
10339 * doc/autoconf.texi: Use @kbd for user input.

10344 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
10345 Don't use nested parenthesization. This patch was originally
10346 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
10347 but somehow it didn't get incorporated then.
10348 * doc/autoconf.texi (Limitations of Usual Tools):
10349 Clarify remark about sed and nested parenthesization.
10351 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
10352 Report an error if the size cannot be determined even though
10353 the type exists.
10354 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10355 Check for `expr' arithmetic overflow, and for compilation failure,
10356 and invoke a new argument $4 if either is discovered.
10357 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
10358 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
10360 2001-09-28 Akim Demaille <akim@epita.fr>
10362 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: New.

10372 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
10374 2001-09-27 Akim Demaille <akim@epita.fr>
10376 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
10377 generates too many bug reports.
10379 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
10380 status when executing the ACTION-IF-FALSE.
10381 * tests/base.at (AC_TRY_*): Rename as...

10386 (Broken/missing compilers, AC_PROG_CPP with warnings)
10387 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
10388 * tests/c.at (Extensions, C keywords)
10389 (Broken/missing compilers, AC_PROG_CPP with warnings)
10390 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
10391 (AC_PROG_CPP requires AC_PROG_CC): here and...
10392 * tests/fortran.at (GNU Fortran 77): there.
10393 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10394 AC_TRY_RUN is about compilation, not shell commands.
10395 (Test Programs): AC_TRY_RUN works as used to be advertised.
10397 2001-09-27 Akim Demaille <akim@epita.fr>
10399 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10400 Raja R Harinath:
10401 Be sure to detect when $LINENO always returns the same value.
10402 Look for the original script, basename($0) is certainly not
10403 enough.
10404 Pass the CLI arguments to `$as_me.lineno'.
10406 2001-09-25 Akim Demaille <akim@epita.fr>
10408 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

10416 of --language now.
10418 2001-09-23 Akim Demaille <akim@epita.fr>
10420 * doc/autoconf.texi (Top): Wrap in @ifnottex.
10422 2001-09-23 Akim Demaille <akim@epita.fr>
10424 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
10425 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
10426 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10427 builddir, buildpath, top_builddir, and top_buildpath.
10428 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10429 the current directory.
10430 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
10431 variables *before* changing the current directory.

10434 variables.
10436 * lib/autotest/general.m4: Do not reset AT_victims.
10437 Don't compute at_srcdir nor at_top_srcdir.
10439 * tests/tools.at: Hence use top_srcdir.
10441 * tests/Makefile.am, tests/autoconf, tests/autoheader,
10442 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
10443 Remove.
10444 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
10445 * tests/wrapsh.in, tests/autoupdate.in: New.
10446 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
10447 * configure.ac: Build the position independent wrappers.
10449 * man/Makefile.am: Now that test wrappers are position
10450 independent, use them and drop dark envvar magic.
10452 2001-09-23 Akim Demaille <akim@epita.fr>
10454 * doc/autoconf.texi (Common Shell Constructs): Rename as...
10455 (Programming in M4sh): this.
10456 Promote to @section.
10458 2001-09-23 Akim Demaille <akim@epita.fr>
10460 * lib/autotest/general.m4 (AT_INIT): Dump config.log last.

10472 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Fix shell
10473 over-escaping.

10483 (Autoconf): Adjust.
10485 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
10487 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

10494 for $LINENO.
10496 2001-09-22 Akim Demaille <akim@epita.fr>
10498 * lib/autoconf/autotest.m4: Create `package.m4'.
10499 * tests/Makefile.am (package.m4): Remove.
10501 2001-09-22 Akim Demaille <akim@epita.fr>
10503 Rely on `$LINENO' when possible instead of `__oline__'.
10505 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
10506 `$LINENO' support replacement when not supported.
10507 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10508 them explicitly to be sure they are not output before this section
10509 (via m4_require). Cosmetic only.
10510 * lib/autoconf/c.m4, lib/autoconf/general.m4,
10511 * lib/autoconf/programs.m4: Replace all the occurrences of
10512 `__oline__' with `$LINENO'.
10513 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
10515 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
10517 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
10518 character (u: -> ue) in a code comment.
10519 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
10520 it works.
10522 2001-09-21 Akim Demaille <akim@epita.fr>
10524 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10525 Suggested by Jim Meyering.
10527 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10529 * lib/autoconf/programs.m4: Use extensions listed in
10530 $ac_executable_extensions when looking for programs.
10532 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10534 * lib/autoconf/general.m4: Fix a small Englisho.
10535 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
10536 setting up ac_dir_suffix and ac_top_builddir.
10537 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10539 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10541 * doc/autoconf.texi (File System Conventions): Clarify the use of
10542 PATH_SEPARATOR.
10543 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
10544 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
10545 be used instead of ':'.
10546 * lib/autotest/general.m4: Replace occurrences of ':' in
10547 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10549 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10551 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10552 arguments. Fixed a typo.
10554 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10556 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10557 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10559 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10561 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10562 * bin/autoupdate.in: Ditto.
10563 * bin/autoheader.in: Reworded a few comments.
10564 * bin/autoconf.in: Reworded help text for a few options.
10565 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10566 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10568 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10570 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10571 already have $file). Set output files to binary mode (helps avoid
10572 CR issues on DOSish systems).
10574 2001-09-19 Akim Demaille <akim@epita.fr>
10576 * lib/autotest/general.m4: Englishoes.
10577 From Tim Van Holder and Alexey Mahotkin.
10579 2001-09-18 Paul Eggert <eggert@twinsun.com>
10581 * doc/autoconf.texi (Common Shell Constructs): New node,
10582 documenting AS_DIRNAME.
10583 (Limitations of Usual Tools): Refer to it when discussing dirname.
10584 Also, update discussion of POSIX standard to reflect latest draft.
10586 * lib/autoconf/c.m4:
10587 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10589 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10590 Do not pass a first argument with leading '-'
10591 to expr, by parenthesizing initial integers that might be negative.
10593 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10594 now merely checks whether it is an error to pass an argument
10595 to getpgrp.
10597 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10598 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10599 whether it is a (compile-time) error to pass an argument to
10600 getpgrp. This simpler test supports the revised documentation,
10601 and is all that AC_FUNC_GETPGRP's users really need.
10603 2001-09-18 Akim Demaille <akim@epita.fr>
10605 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10607 2001-09-18 Akim Demaille <akim@epita.fr>
10609 * doc/autoconf.texi (Limitations of Usual Tools) <find>: More about
10610 `{}'.
10611 * lib/autotest/general.m4 (AT_INIT): Adjust.
10613 2001-09-18 Paul Wagland <paul@wagland.net>
10615 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10616 correctly.
10617 Add test for AS_BASENAME.
10618 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10619 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10620 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10621 * tests/base.at: Fixed the expected responses. The old ones were
10622 one line out...
10623 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10624 the documentation claims it should (and how it behaved in 2.13).
10626 2001-09-18 Akim Demaille <akim@epita.fr>
10628 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10629 the AC_CONFIG_COMMANDS invocation.
10630 This also solves the name clash problems.
10631 Don't set the package's ID.
10632 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10633 No longer to be shipped.
10634 (version.in): Remove.
10635 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10636 * lib/autoconf/status.m4: Adjust.
10637 Use `m4_PACKAGE_STRING'.
10638 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
10639 the only optional argument is the name of the test suite.
10640 Expect `package.m4' to define the package signature.
10641 * lib/autom4te.in (Autotest): Add `package.m4?'.
10642 * tests/Makefile.am (package.m4): New.
10643 * tests/suite.at: ifnames is a victim.
10645 2001-09-18 Akim Demaille <akim@epita.fr>
10647 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
10648 AC_LIBSOURCE, AC_CONFIG_FILES.
10649 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
10650 program version string doesn't match the package's.
10651 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
10652 after `(cached)'.
10654 2001-09-17 Paul Eggert <eggert@twinsun.com>
10656 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10657 Allow expression to return any value that can fit into unsigned long
10658 (not int, as before). Check for output errors.
10660 2001-09-17 Bruno Haible <haible@ilog.fr>
10662 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
10663 Always include <stdio.h> and <stdlib.h>. Evaluate
10664 the expression in an extra function before these includes. Call
10665 fprintf "%d" only after ensuring the argument is of type 'int'.
10666 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
10668 2001-09-17 Paul Eggert <eggert@twinsun.com>
10670 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
10671 or CFLAGS=-O5. In that case, the linker has a relaxed view of
10672 fatal errors, and AC_CHECK_LIB causes it to include libraries even
10673 when they don't exist.
10675 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,

10677 need it.
10679 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
10680 version with the version used by fileutils 4.1, except use

10726 * lib/autotest/general.m4 (AT_INIT): Create and remove
10727 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple

10838 2001-09-05 Akim Demaille <akim@epita.fr>

10841 the maintainer is dumb enough to do that...
10843 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
10844 excellence in M4 quotation: consider `__file__' is active.
10846 And BTW, when invoking m4, pass the --include in the right order:
10847 the wrong one.
10849 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
10850 4m.

10877 New, extracted from main.
10878 Use IO::File wherever possible.
10879 (input.m4): Be constant, use -I instead of hard coding $tmp.

10881 Don't invoke `_au_disable', since ac was not loaded, but just
10882 `unm4.m4'.
10884 2001-08-31 Akim Demaille <akim@epita.fr>
10886 Version 2.52d.

10911 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
10912 (testsuite Scripts): There is no such thing as `atconfig.in'.
10913 And actually one diagram is missing: test suite runtime.
10915 2001-08-31 Akim Demaille <akim@epita.fr>
10917 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
10918 inverse order.
10920 2001-08-31 Akim Demaille <akim@epita.fr>
10922 * bin/autoupdate.in (@include): `installcheck' revealed the path
10923 to m4sugar was lacking!
10925 2001-08-31 Akim Demaille <akim@epita.fr>
10927 * man/Makefile.am (.x.1): We really have to pass
10928 autom4te_perllibdir.
10930 2001-08-31 Akim Demaille <akim@epita.fr>
10932 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to

10938 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
10939 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
10940 Use directly autom4te, not autoconf.

10965 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
10966 (autoheader): Pass --force since the test suite goes too fast for
10967 the time stamps.
10968 Adjust to the new autoheader messages.
10970 2001-08-31 Akim Demaille <akim@epita.fr>
10972 * bin/autoheader.in: Handle the acconfig.h etc. junk files.

10984 `autoheader: `config.hin' is created'.
10985 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
10987 2001-08-31 Akim Demaille <akim@epita.fr>
10989 * bin/autoheader.in: Rewrite in Perl.

10995 Map --localdir, --autoconf-dir onto it.
10996 Forward autom4te's options instead of interpreting them.
10997 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
10998 There is no such envvar since the inception of autom4te.cfg.
10999 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11000 * bin/autoupdate.in: Adjust, and perform more control.

11007 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11008 optionally `FILE'.

11011 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11013 2001-08-31 Akim Demaille <akim@epita.fr>
11015 * configure.ac: Also find tested executables in bin.
11016 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11017 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11018 installed peer executables, only PATH is allowed to resolve it.
11019 Pass `autoconf_dir' via options, not via invisible envvars.
11020 * lib/Autom4te/General.pm (&find_peer): Remove.
11021 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11022 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11023 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11024 find the executables for it.
11025 * tests/Makefile.am: Major cleanup. Too lazy to document...
11026 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11027 We only need PERL.
11028 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11029 indeed related to running the test suite, while passing
11030 --autoconf-dir and others is related to running non installed
11031 Autoconf executables. So don't do that, leave it to...
11032 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11033 * tests/autoscan: New.
11034 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11035 refer to library files: rely on --language.

11039 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:

11048 2001-08-29 Akim Demaille <akim@epita.fr>
11050 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11051 Suggested by Paul Eggert.
11053 2001-08-29 Akim Demaille <akim@epita.fr>
11055 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11056 download in a tmp dir.
11058 2001-08-29 Akim Demaille <akim@epita.fr>
11060 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

11079 * lib/autotest/general.m4: Use
11080 foo=`(command) 2>/dev/null`

11083 (at-devnull): Rename as...
11084 (AT-devnull): this.
11085 (--clean): Remove AT-* files too.
11086 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.

11121 * lib/autotest/general.m4 (AT_INIT): Log the command line.

11593 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11595 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11597 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11599 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11600 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11601 * doc/autoconf.texi (C Compiler Characteristics): Update
11602 documentation for AC_C_BIGENDIAN.
11604 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11606 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11607 magic values from an object file when cross-compiling.
11608 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11610 2001-08-10 Akim Demaille <akim@epita.fr>
11612 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11613 effects.
11614 Suggested by Russ Allbery.
11616 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11618 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11619 current $prefix to the sub-configures.
11621 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11623 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
11624 extension (needed on BeOS). Reported by Guido van Rossum.
11626 2001-08-09 Akim Demaille <akim@epita.fr>
11628 * bin/autom4te.in ($icache): Load it only if older than autom4te.
11630 2001-08-07 Akim Demaille <akim@epita.fr>
11632 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11633 removed.
11634 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11635 No need to remove the files before and after the each test, before
11636 each test and at the end of the suite is enough.
11637 Display only the children `times', not the shell's.
11638 If the test failed or was skipped, at-times is not available.
11640 2001-08-07 Akim Demaille <akim@epita.fr>
11642 Always produce testsuite.log, including when there are no
11643 failures. This helps getting information on skipped tests, and
11644 duration of the tests. Err, implement the latter btw.
11646 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
11647 Dump information on the first run of each test.
11648 (AT_CLEANUP): Create `at-times' containing the duration of the
11649 test group.
11651 2001-08-07 Akim Demaille <akim@epita.fr>
11653 The use of `dumpstat' revealed that `len' was used although it
11654 should not. m4_text_wrap was using it, but in the Autoconf world
11655 where it is legal. Hence (i) test M4sh in its own world, not
11656 Autoconf's, and (ii), ahem, fix the bug :)
11658 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
11659 does not like `' instead of [].
11660 (AT_INIT): Forbid `^_?AT_'.
11661 And don't output such tokens.
11662 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
11663 `script.as', and `autom4te.cache'.
11664 Remove `empty' and `macro' which are no longer used.
11665 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
11666 * tests/m4sugar.at: Use it.
11667 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
11669 2001-08-07 Akim Demaille <akim@epita.fr>
11671 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
11673 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
11675 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
11677 2001-08-04 Akim Demaille <akim@epita.fr>
11679 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
11680 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
11681 AC_TRY_LINK.
11682 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
11683 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
11684 (AC_F77_MAIN): Likewise.
11686 2001-08-04 Akim Demaille <akim@epita.fr>
11688 Don't rely on M4sugar outputting the patterns in files, since we
11689 might process the output _without_ running m4, hence without these
11690 files.
11692 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
11693 * bin/autom4te.in (@Request::includes): Remove, unused.
11694 (@Request::source): Rename as...
11695 (@Request::input): this.
11696 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
11697 (&handle_output): Fetch the patterns from the traces.
11698 `$forbidden' and `$allowed' are constant: use m//o.
11699 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
11700 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
11702 2001-08-04 Akim Demaille <akim@epita.fr>
11704 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
11705 autoconf', i.e., in addition to caching traces, cache the output.
11707 * bin/autom4te.in (Request::cache): Rename as...
11708 (Request::id): this.
11709 ($cache, $icache, $tcache, $ocache): New.
11710 (&handle_m4): Save M4 output in the cache instead of $tmp.
11711 (&handle_output): Adjust.
11712 (&up_to_date_p): Check that the output cache is up to date too.
11713 (top level): Run `&handle_m4' iff force or the cache is invalid.
11714 Run `&handle_output' if the output cache is more recent.
11716 2001-08-04 Akim Demaille <akim@epita.fr>
11718 * bin/autom4te.in ($force): New.
11719 (&parse_args, &print_usage): -f, --force is a new option.
11720 (&handle_output): CPP directives might have spaces after `#'.
11721 (&parse_args): The first file only can be frozen.
11723 2001-08-04 Akim Demaille <akim@epita.fr>
11725 Don't let autom4te compute the `include' traces several times:
11726 first check that the trace cache file is up to date, and then
11727 compare its timestamp with that of the output.
11729 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
11730 the preamble. Don't require 5.005 as Autom4te::General does it,
11731 and better yet (use `use', not `require'!).
11732 * lib/Autom4te/Struct.pm: Rename the last occurrences of
11733 Class::Struct as Autom4te::Struct.
11734 * lib/Autom4te/General.pm (File::stat): Use it.
11735 (&mtime): New, export it.
11736 * bin/autom4te.in: Use it.
11737 Declare `$req' is invalid if it is outdated.
11738 Don't declare it valid before saving it if something went wrong.
11740 2001-08-04 Akim Demaille <akim@epita.fr>
11742 Autom4te shall not encode Autoconf data, and preselecting traces
11743 must be proposed to the users.
11745 * bin/autom4te.in (@required_trace): Remove.
11746 (@preselect): New.
11747 (&parse_args, &print_usage): -p, --preselect is a new option.
11748 (&up_to_date_p): Adjust.
11749 * bin/autoconf.in: Preselect some Autoconf macros.
11751 2001-08-04 Akim Demaille <akim@epita.fr>
11753 * tests/tools.at (autoconf --trace: user macros): Check traces on
11754 macros invoked without arguments, and macros invoked with multiple
11755 lines arguments.
11757 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
11759 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
11760 arguments.
11762 2001-08-03 Akim Demaille <akim@epita.fr>
11764 * bin/autoconf.in ($@): Work around the usual sh bug.
11765 From Nicolas Joly.
11767 2001-08-03 Akim Demaille <akim@epita.fr>
11769 Clean up the handling of the M4 builtins tracing exception.
11771 * bin/autom4te.in (Request::request): Don't complete M4 builtins
11772 trace requests.
11773 (@m4_builtins): Rename as...
11774 (@m4_builtin): this.
11775 (%m4_builtin_alternate_name): New.
11776 (&parse_args): Complete the trace requests with alternate names.
11777 (&handle_traces): Hence no longer do it here.
11778 (&trace_requests): Remove, unused.
11780 2001-08-03 Akim Demaille <akim@epita.fr>
11782 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
11783 m4_if, and m4_wrap.
11785 2001-08-03 Akim Demaille <akim@epita.fr>
11787 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
11788 (m4_divert_pop): Dump the whole diversion stack when a diversion
11789 mismatch happens.
11790 * bin/autom4te.in (&handle_output): Remember of the first
11791 occurrence of a possibly undefined macro, not the last.
11792 Complain about the possibly undefined macros in the same order as
11793 the appear in the output.
11794 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
11795 * tests/tools.at (autoconf: forbidden tokens, basic)
11796 (autoconf: forbidden tokens, exceptions): No longer sort
11797 autoconf's stderr, as it is now deterministic.
11798 Check that `dnl' is caught.
11800 2001-08-01 Akim Demaille <akim@epita.fr>
11802 * configure.ac: Bump to 2.52c.

11814 2001-08-01 Akim Demaille <akim@epita.fr>

11817 `die'.
11818 (&END): New.
11819 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
11820 `END', as `Autom4te::General::END' will be triggered.
11821 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
11822 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

12012 2001-07-18 Akim Demaille <akim@epita.fr>
12014 The C-Fortran 77 hooks are available only once AC_F77_DUMMY_MAIN

12037 The runtime test for AC_FUNC_GETPGRP fails when prototypes are
12038 used. Well, then use the prototypes when you can, and runtime as
12039 a last resort.

12134 For some AWK, such as on HPUX 11, `xfoo' does not match `foo|^bar'.
12135 Reported by Michael Elizabeth Chastain.
12137 * autoconf.in: Refuse such AWK.
12138 * configure.in: Likewise.
12139 * Makefile.am (acversion.m4): Do not use move-if-change this file

12219 earlier if there are.
12221 2001-07-03 Akim Demaille <akim@epita.fr>

12251 dummy alternate main is required even if the user provides her own
12252 'main'.
12253 (AC_F77_MAIN): New macro to detect whether it is possible to
12254 provide an alternate 'main' function name, using the 'main' from
12255 the Fortran libraries.
12256 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
12257 cross-language link tests can be performed successfully.
12258 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12259 after $LIBS, for consistency; this should be the general rule since

12263 2001-06-29 Pavel Roskin <proski@gnu.org>
12265 * atgeneral.m4 (AT_CHECK): Add a newline to the end of
12266 at-stdout and at-stderr instead of removing the newline
12267 from the echo output, which is not guaranteed to work.

12337 2001-06-23 Akim Demaille <akim@epita.fr>
12339 * acgeneral.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS): Consider

12380 Automake), include the separator themselves.
12382 * acgeneral.m4 (AC_ARG_VAR): Be sure not to leave extra `;'.
12384 2001-06-19 Tim Van Holder <tim.van.holder@pandora.be>
