1 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
4 assignments in `at_debug_args', so that we put them correctly
5 in the `run' script.
6 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
7 Reported by Eric Blake.
9 2006-04-11 Eric Blake <ebb9@byu.net>
11 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
12 top-level tests after micro-suite has been run. Used in...
13 (Debugging a successful test, Debugging script and environment),
14 (Debugging a failed test): ...these new tests. The first of these
15 is fixed by...
16 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
17 macro, split out from...
18 (AT_INIT): ...here, so that using -d also generates a run script.
19 Document that -d inhibits top-level logging.
20 * doc/autoconf.texi (testsuite Invocation): Document that -d only
21 inhibits top-level logging; debug scripts are created.
23 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
24 check.
25 * tests/autotest.at (Empty test, Empty check): New test to check it.
27 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
28 from gcc.
30 2006-04-10 Stepan Kasal <kasal@ucw.cz>
32 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
33 the files if a problem appears. Make the empty *.at files
34 read-only, too. Proposed by Ralf Wildenhues.
36 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
38 * config/Makefile.am: Add comment to force updated Makefile.in.
40 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
41 space only patch to this file, this patch causes the Makefile.in
42 files that include freeze.mk to be updated, and thus have a
43 newer time stamp again, which in turn makes a pristine CVS
44 checkout have correct time stamps.
46 * Makefile.maint (cvs-sv): New macro, to be used..
47 (config.guess-url_prefix, config.sub-url_prefix)
48 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
49 point to CVS text checkout of Gnulib files.
50 (copyright-check): Bump current year.
51 (announcement): Do not hard-wire `./announce-gen'.
52 (cvs-update): Propagate failures of `cvs' and `move-if-change'
53 correctly.
54 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
55 `chmod +x'.
56 (wget_files): Update config.guess, config.sub, texinfo.tex by
57 `wget-update', now that their URLs work again.
59 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
61 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
62 Problem noted by Paul D. Smith.
64 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
66 * doc/autoconf.texi: Remove unused words from word list.
67 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
68 .x-sc_trailing_space: New files.
70 * doc/standards.texi: Sync from gnulib.
72 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
73 `LIBOBJDIR' as experimental.
75 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
76 with a target directory; it's internally implemented as `cp'
77 anyway, but since Autoconf advertises the possibility to use
78 a target directory when LN_S is `ln -s', we need to find out.
79 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
80 analyzed by Keith Marshall <keith.marshall@total.com>.
82 * THANKS: Update.
84 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
86 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
87 confdefs.h as-is. In general, if it has backslash-newline or the
88 like, then it doesn't work either to sort or to remove empty
89 lines.
91 2006-04-09 Stepan Kasal <kasal@ucw.cz>
93 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
95 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
97 * lib/autom4te.in (Automake-preselections): Preselect
98 _AM_SUBST_NOTMAKE.
100 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
102 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
103 apostrophe within a single-quoted string, as this is the usual
104 tradition and is easier to read than '"'"'. Don't rely on the
105 shell treating "$/" like '$/'. Use a more-consistent indenting
106 style for the trap.
108 2006-04-09 Eric Blake <ebb9@byu.net>
110 * tests/autotest.at (Backquote command substitution),
111 (Multiline backquote command substitution): Remove mistaken
112 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
113 applied...
114 (Parenthetical command substitution, Multiline parenthetical
115 command substitution): here.
117 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

147 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
148 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
149 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
150 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
151 (C Compiler): Move AC_C_LONG_DOUBLE to ...
152 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
153 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.

174 New macros.
176 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
177 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
179 2006-04-08 Stepan Kasal <kasal@ucw.cz>
181 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
182 of the warning introduced by the 2001-08-28 change.
184 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
185 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
187 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
188 variables shall be overriden by the cache.

190 that contains braces.
192 2006-04-07 Stepan Kasal <kasal@ucw.cz>
194 Revert the patch from 2006-04-01 and only improve
195 _AS_DETECT_BETTER_SHELL:
197 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
198 skip nonexistent directories.
199 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
200 only shell candidates which exist.
201 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
202 * lib/autotest/general.m4 (AT_INIT): No need to give three
203 parameters to _AS_PATH_WALK.
205 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
206 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
208 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
209 distinguish m4sugar macros.
210 * tests/tools.at (autoupdating with aclocal and m4_include):
211 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
212 test case by Noah Misch <noah@cs.caltech.edu>.
214 2006-04-07 Stepan Kasal <kasal@ucw.cz>
216 Revert my change from 2006-03-17, in other words:
217 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
218 and DUALCASE=1.
219 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
220 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
221 it is set.
223 2006-04-07 Eric Blake <ebb9@byu.net>
225 * doc/autoconf.texi (Programming in M4sh): Document that
226 AS_MKDIR_P exits the script on failure.
227 * lib/autotest/general.m4: Remove redundant AS_ERROR.
229 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
231 * config/elisp-comp, config/install-sh, config/mdate-sh,
232 config/missing, config/mkinstalldirs: Sync from Automake.
234 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
235 from Automake.
237 * doc/make-stds.texi: Sync from gnulib.
239 2006-04-06 Eric Blake <ebb9@byu.net>
241 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
242 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

246 Eric Blake <ebb9@byu.net>,
247 Paul Eggert <eggert@cs.ucla.edu>,
248 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
250 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
251 whether `set' quotes correctly: redirect stderr of the tested
252 `set', and use a subshell, for Ultrix; use `sed' instead of
253 `grep' for zsh `set' which may write binary output; match only
254 at the beginning of a line, to avoid false positives.
255 In order to avoid false positives by unrelated variables with
256 multiline content, put the dump algorithm in a subshell and
257 unset all variables containing newlines (except some which are
258 special to the shell). Warn about cache variables that are
259 unset.
261 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
263 * config/config.guess, config/config.sub, config/texinfo.tex:

271 (AC_ARG_VAR): Do test this now.
272 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
273 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
274 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
275 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
277 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
278 shell issue with double-quoted command substitutions of native
279 commands.
280 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
281 Marshall.
283 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
284 no file matches the glob, discard the warning, set `nullglob'.
285 (syntax-check): Likewise.
286 (sc_cast_of_x_alloc_return_value): Likewise.
287 (sc_cast_of_alloca_return_value, sc_error_exit_success)
288 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)

303 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
304 ac_config_<foo>s again, sometimes normalized, sometimes not.
305 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
306 (AC_CONFIG_COMMANDS): Do not do so here.
307 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
308 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
309 2005-07-25 rewrite. Noticed by Noah Misch.
311 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
312 _AC_PRESERVE_HELP_ORDER, ...
313 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
315 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
316 inside m4_expand_once; it is redundant.
318 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
319 for --help from Cygnus `configure.'
321 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
323 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
324 on a patch proposed by Ralf Wildenhues.
326 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
328 * lib/autoconf/status.m4: Replace <space>''<tab> with
329 <tab><space> where this makes sense.
331 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
332 Noah Misch <noah@cs.caltech.edu>
334 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
335 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
336 * doc/autoconf.texi (Help Formatting): New node.
337 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
339 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
341 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
342 lib/autoconf/specific.m4, lib/autoconf/status.m4,
343 lib/autoconf/types.m4, lib/autotest/general.m4,
344 tests/mktests.sh, tests/torture.at: White space cleanup:
345 remove some SPACE before TAB, or add quoting ('' or @&t@).
347 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
349 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
351 2006-04-05 Eric Blake <ebb9@byu.net>
353 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
354 empty test suite works.
355 * tests/autotest.at (Empty test suite): Remove xfail.
357 2006-04-05 Noah Misch <noah@cs.caltech.edu>

363 normalizing it, consistent it with previous releases.
364 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
366 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
368 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
369 Use simplified args that Eric Blake originally suggested.
371 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
373 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
374 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
375 Use 'comm' rather than N instances of grep; this also fixes a bug
376 whereby substrings were incorrectly matched, causing us to not
377 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
378 (exclude_list): Exclude empty macros.
379 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
381 Use awk rather than grep -E or egrep, to avoid
382 portability problems with regular expressions containing newlines.
383 (exclude_list, ac_exclude_list, au_exclude_list, ac_exclude_script):
384 Switch from grep to awk syntax.
385 (ac_exclude_script): Renamed from ac_exclude_egrep.
386 (au_exclude_script): Renamed from au_exclude_egrep.
388 2006-04-04 Noah Misch <noah@cs.caltech.edu>

391 a subdirectory subject to Cygnus `configure'.
392 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
394 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
395 report request when we have no AC_PACKAGE_BUGREPORT.
397 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
399 * THANKS: Update.
401 * tests/mktests.sh: Update copyright year in the header of the
402 generated files.
404 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
405 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
406 typedef'ed restricted pointer, to catch a compiler bug on
407 HP-UX 11.x, and fix warnings so it passes with -Werror.
408 (_AC_PROG_CC_C99): Likewise.
409 Reported by Albert Chin <china@thewrittenword.com>.
410 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

419 2006-04-03 Noah Misch <noah@cs.caltech.edu>
421 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
423 2006-04-03 Eric Blake <ebb9@byu.net>
425 * THANKS: Add myself.
427 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
429 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
430 to log, point to testsuite output tree.
432 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
434 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
435 * doc/autoconf.texi (Function Portability): Mention that C++
436 has trouble with 'exit'.
437 (Guidelines): Test programs shouldn't use 'exit'.
438 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
439 Remove; all uses removed.
440 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):
441 Return from 'main' instead of calling 'exit'.

462 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
463 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
464 ac_file to the name of the default output filei and call
465 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
466 initial `rm' of the candidate files...
467 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
468 the same list in subsequent `rm' calls, and for the temporary
469 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
470 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
471 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
472 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
473 no longer needed) by libtool. Make it a cache check.

475 copied here by mistake.
476 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
477 _AC_COMPILER_EXEEXT.

514 subordinate tools.
515 * lib/Autom4te/General.pm (getopt): Make -v and -d incremental.
516 * doc/autoconf.texi (autoreconf Invocation): Document it.
518 * doc/autoconf.texi: Use `Cygwin', `MinGW', and `license' consistently.

547 Dalibor Topic <robilad@kaffe.org>, and against Autoconf 2.57 by
548 Kristian Kvilekval <kris@cs.ucsb.edu>.
550 2006-04-01 Stepan Kasal <kasal@ucw.cz>
552 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
553 switch all of them on and of when necessary. Fixes the bug when
554 m4sugar macros (e.g., m4_define) were expanded after the first

1252 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
1253 by the function rather than ignoring it.
1254 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
1255 comparing its address. Intel's interprocedural optimization was
1256 outsmarting the old heuristic. Problem reported by

1274 Stepan Kasal <kasal@ucw.cz>
1276 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
1277 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
1278 make its content writable before removing it. Remove an errorneous
1279 comment from the end, where the logs of the failed tests are copied
1280 to the main log file.
1282 2005-09-27 Stepan Kasal <kasal@ucw.cz>

1289 problems if the testsuite were running too fast.
1291 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1293 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

1305 suggested by Ben Elliston. Handle weird characters correctly.
1307 2005-09-06 Stepan Kasal <kasal@ucw.cz>
1309 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
1310 calls, so that the final expansion of this macro is shorter.
1311 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
1312 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
1313 the cleanup there. Use AS_VAR_* macros, to be more general.
1314 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
1316 * lib/autoconf/general.m4: Use AS_IF where appropriate.
1318 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

1336 2005-08-26 Stepan Kasal <kasal@ucw.cz>
1338 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
1339 in the example. Reported by Bruno Haible.
1340 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
1341 "if $undefined_var;" succeeds with my shell.
1343 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
1344 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
1345 but change the m4_divert_text to m4_divert_once.

1360 Stepan Kasal <kasal@ucw.cz>
1362 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
1363 first header appears, define AH_HEADER.
1364 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
1365 Update limitations about when to call AC_CONFIG_HEADERS.
1366 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
1367 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
1368 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
1369 ``Configuration Actions''; fix their index entries.
1371 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
1372 options correctly. Process N-M as M-N if M is smaller than N.
1373 Process ranges correctly so that N-N will run only N.
1374 Sort and uniquify the tests that will be run. If there is more
1375 than one test, reinsert the banners for the tests.

1381 before passing the macro name to AH_TEMPLATE.
1383 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status

1404 2005-08-16 Stepan Kasal <kasal@ucw.cz>
1406 When building in place, set srcdir="."; suggested by Tim Van Holder.
1408 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
1409 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
1410 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
1411 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
1412 does not mean "no --srcdir option".
1414 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1416 * tests/autoscan.at (autoscan): New file.
1417 * tests/suite.at: Use it.
1418 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
1419 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
1421 * tests/autotest.at (Keywords): Test keywords combinations.
1423 2005-08-12 Stepan Kasal <kasal@ucw.cz>
1425 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
1426 add "2>&1"; gzip 1.2.4 prints help on stderr.
1428 2005-07-27 Stepan Kasal <kasal@ucw.cz>
1430 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
1431 was pushdef'ed twice while popped only once. Push it only once.
1432 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
1434 2005-07-26 Stepan Kasal <kasal@ucw.cz>
1436 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
1437 prefixed by mere "===", not "configure: === ".
1439 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
1441 * Makefile.maint: Update from Bison.
1443 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
1444 "<tab>" in comment, so that the point is understandable.
1446 2005-07-25 Stepan Kasal <kasal@ucw.cz>
1448 Rewrite substantial part of lib/autoconf/status.m4.
1449 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
1450 and CONFIG_COMMANDS are not processed in four separate loops.
1451 Instead, there is one main loop. This alows that the common code
1452 is expanded only once, thus config.status (and configure) is smaller.
1454 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
1455 the AC_LIST_FILES and cousins macros are no longer used.
1457 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
1458 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
1459 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
1460 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
1461 contain the initialization, nor the for loop, nor the associated
1462 commands; all these go to ...
1463 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
1464 _AC_OUTPUT_CONFIG_STATUS.
1465 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
1466 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
1467 (_AC_OUTPUT_FILE): The creation of the sed script ...
1468 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
1469 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
1470 _AC_OUTPUT_MAIN_LOOP.
1471 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
1472 _AC_CONFIG_COMMANDS): Use ...
1473 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
1474 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
1475 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
1476 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
1477 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
1478 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
1479 ... new macros.
1480 (_AC_CONFIG_UNIQUE): Update.
1481 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
1482 Replaced by this ...
1483 (_AC_LIST_TAGS): ... new common macro.
1484 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
1485 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
1486 (_AC_LIST_TAG_COMMANDS): ... new common macro.
1487 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
1488 this didn't belong to the `config commands' section.
1489 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
1490 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
1491 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
1492 to the `config commands' section either.
1493 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
1494 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
1496 ... and many changes to the comments nearby.
1498 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
1499 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
1500 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1501 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
1502 (#define header templates): The comment at the top of the generated
1503 header now includes the name(s) of the source file(s).
1505 Several unrelated small changes:
1507 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
1508 parameter to AC_DIAGNOSE.
1509 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
1510 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
1511 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
1512 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
1513 with AU::AC_OUTPUT.
1514 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
1515 in AC_OUTPUT doesn't double-quote it either.
1516 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
1517 parameters.
1519 2005-07-10 Stepan Kasal <kasal@ucw.cz>
1521 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
1522 versions of Portland Group compiler produce single- and double-quoted
1523 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
1524 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
1526 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
1528 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
1529 This is a corrected version of yesterday's patch.
1531 2005-07-07 Stepan Kasal <kasal@ucw.cz>
1533 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
1534 path, too; insert a "===" to emphasize the line.
1536 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
1537 ac_cv_build_alias to ac_build_alias.
1538 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
1540 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
1541 change eliminates it. Problem reported by Alexandre Duret-Lutz.
1542 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
1543 (AC_ARG_VAR): ... here.
1544 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
1545 target_alias.
1547 Keep a list of all precious variables and process them with one simple
1548 for loop, instead of expanding all commands, or, OTOH, complicated
1549 processing of output of "set".
1550 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
1551 variable names in new macro...
1552 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
1553 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
1554 a loop to assign all ac_env_* and ac_cv_env_* variables.
1555 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
1556 to INIT_PREPARE.
1557 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
1558 its value to shell variable ac_precious_vars and call
1559 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
1560 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
1561 _AC_ARG_VAR_VALIDATE.
1563 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
1564 and the AC_SUBSTs ...
1565 (AC_INIT): ... here.
1567 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
1568 the ac_subst_files section in config.log.
1570 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

1579 Fix problems reported by Nicolas Joly.
1580 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
1581 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
1582 They are generated by the Tru64 v5.1B shell.
1584 2005-07-05 Stepan Kasal <kasal@ucw.cz>
1586 Fix my changes from 2005-07-01; reported by Noah Misch.
1587 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
1588 description, the macro now accepts only a single tag.
1589 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
1591 Fix cases when the varsions of Autoconf and Autotest don't match.
1592 Reported by Noah Misch.
1593 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
1594 at_top_builddir, for compatibility with older autotest.
1595 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
1596 is not set, use at_top_builddir, for compatibility with older
1597 versions of autoconf.
1599 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
1601 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
1602 Problem reported by Patrick Welche.
1604 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
1606 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
1607 sed substitution command, so that we allow | in program prefixes
1608 and program suffixes. (& is a problem anyway; we're not fixing
1609 that here.)
1610 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
1611 configure_input, top_builddir, srcdir, etc.
1612 * lib/autotest/general.m4 (AT_INIT): Likewise, for
1613 PATH_SEPARATOR in AUTOTEST_PATH.
1615 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
1617 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
1618 for loop over config.site files using `set', to allow
1619 directory names containing IFS characters.
1621 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
1623 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
1624 directories with weird names. Apparently some people like living
1625 on the edge. However, improve the test that "pwd" actually does
1626 report a name for the working directory.

1629 2005-07-01 Stepan Kasal <kasal@ucw.cz>

1643 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
1645 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
1646 document to output the default config_* lists to config.status.
1647 Don't recognize option --file, if the functionality is not there.
1648 Likewise for --header; moreover, recognize --he and --h as shortcuts
1649 for --help in that case.
1651 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
1652 matches the order of execution. No code changed.

1673 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
1674 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
1675 (AC_SUBST): Call it.
1676 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
1677 the directory specific variables; but don't call it for configure_input.
1679 2005-06-28 Derek Price <derek@ximbiot.com>
1681 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
1682 addition.
1684 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
1686 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
1687 directory have inherent problems with special characters like spaces,
1688 due to limitations in Make syntax. Problem reported by Alexandre
1689 Duret-Lutz.
1690 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
1691 Also, fix Tru64 porting problem with shell patterns,

1703 from Justace Clutter.
1704 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
1705 variable into diagnostic. Make the diagnostic an error, not a warning,
1706 because we really don't support spaces and suchlike in dir names.
1707 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
1708 Don't worry about backslashes in srcdir; it can't happen now.
1709 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
1710 Simplify ac_optarg handling.
1711 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

1719 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
1721 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
1722 that '\|' is not allowed in BREs; recommend using newline separated
1723 list of patterns instead of multiple -e options.
1725 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
1727 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

1733 2005-06-21 Stepan Kasal <kasal@ucw.cz>
1735 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
1736 b, t, r, w commands require single space, while : cannot have any.
1737 (Special Shell Variables): Fix sed code this in the example.
1738 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
1739 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
1741 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
1742 expand to the empty list. Don't use two pairs of m4_changequote,
1743 it's not necessary.
1745 2005-06-20 Derek Price <derek@ximbiot.com>
1747 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
1749 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
1751 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
1752 * doc/autoconf.texi:
1753 Don't mention Solaris versions so much, if a
1754 problem is common to all extant versions of Solaris. Say "SunOS
1755 4" instead of "SunOS" for SunOS 4.
1756 (awk): Mention more of the limitations of traditional Awk.
1757 (cat): Don't talk about cat -v.
1759 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
1761 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
1762 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,
1763 but the implementation is entirely different and is designed
1764 to be compatible with glibc strverscmp.
1765 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
1767 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
1768 on Mac OS X 10.4 reported by Peter O'Gorman in:
1769 http://lists.gnu.org/archive/html/autoconf-patches/2005-06/msg00041.html
1770 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
1771 Use shell builtins rather than 'expr', to work around expr bug.
1773 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
1775 * doc/autoconf.texi: "filesystem" -> "file system".
1776 "behaviour" -> "behavior".
1777 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
1778 * lib/autoconf/general.m4: Omit blank after ":" sed command,
1779 as per POSIX.
1780 * lib/m4sugar/m4sh.m4: Likewise.

1782 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
1784 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
1785 (.x.1): Ignore the time stamp in the .TH line when deciding whether
1786 to update the man page. That way, we don't have to check in new
1787 man pages every month.
1789 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
1790 quotes and backslashes. Patch from Derek Price.
1792 2005-06-10 Derek Price <derek@ximbiot.com>
1794 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
1795 AS_TR_SH.
1797 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
1799 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
1800 -u, since it outputs chatter if the input files are the same.
1801 Problem reported by Ralf Menzel.
1803 2005-06-08 Derek Price <derek@ximbiot.com>
1805 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
1806 renaming them since they are about to be redefined anyhow.
1808 2005-06-08 Derek Price <derek@ximbiot.com>
1810 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
1811 redefined M4 macros to this node. Document m4_include & m4_sinclude.
1812 Move m4_undefine to alphabetical order.
1814 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
1816 * README: Recommend GNU M4 1.4.3 or later.
1817 * doc/autoconf.texi (Introduction): Likewise.
1818 Reword to avoid some formatting glitches.
1819 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
1820 Clarify explanation of HP compiler bug.
1821 Redo example output tp match current CVS snapshot.
1822 Use @example.org in email addresses when the examples
1823 might get inadvertently cut-and-pasted into user code.
1824 Remove example of autom4te usage that doesn't seem to work now.
1825 Use modern AC_INIT (except when the example is meant to be
1826 shown with Autoconf 2.13).
1827 Update ksh info for Solaris 9 and later.
1828 KB -> kB.
1829 Modernize description of Automake versions a bit.
1830 Don't claim a future version of Autoconf is near.
1831 * doc/install.texi: Reword to avoid some formatting glitches.
1833 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1835 * doc/autoconf.texi: Add [] to examples, so that the manual
1836 follows its own advice about quoting better.
1837 Reword to avoid some formatting glitches.
1838 * doc/installt.exi: Reword to avoid some formatting glitches.
1840 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
1841 Tru64 ksh pattern matching bug. Reported against Libtool by
1842 Albert Chin <libtool@mlists.thewrittenword.com> and
1843 Nicolas Joly <njoly@pasteur.fr>.
1845 2005-06-06 Stepan Kasal <kasal@ucw.cz>
1847 m4_cdr of one-member list was [[]] (one-member list containing an
1848 empty string) instead of [] (an empty list. Callers were skewed to
1849 match this misbehaviour. As a consequence of this:
1850 - m4_foreach([x], [], [foo]) expanded to `foo', while
1851 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
1852 This bug has been fixed:
1854 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
1855 expand to an empty string; print error msg if called without
1856 an argument list.
1857 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
1858 misbehaviour; handle [] and [[]] correctly.
1860 2005-06-06 Stepan Kasal <kasal@ucw.cz>
1862 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
1863 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
1864 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
1866 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
1868 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
1869 swallow records with more than 99 fields.
1870 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
1871 parse the long line.
1873 2005-06-04 Stepan Kasal <kasal@ucw.cz>
1875 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
1876 swallow literals longer than 399. Reported by Ralf Wildenhues.
1877 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
1878 to workaround this limitation.
1880 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
1882 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
1883 to gfortran, and make these the first two compiler names
1884 checked (following the general autoconf preference for gcc).
1886 2005-06-03 Stepan Kasal <kasal@ucw.cz>
1888 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
1889 (DISTCLEANFILES): Remove $(check_SCRIPTS).
1890 (testsuite): Make sure autotest.m4f is up-to-date before using it.
1892 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
1894 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
1895 expression of unbounded size when processing the --list
1896 option. This runs afoul of a limit of 399 bytes per regular
1897 expression on AIX. Problem reported by Ralf Wildenhues.
1899 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
1901 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
1902 * doc/autoconf.texi (Particular Headers): Reword example
1903 for multiline stdbool replacement.
1904 (Setting Output Variables): Reword text a bit. Don't
1905 give all the details about |#_!!_#|.
1906 Reword description of line replacement.
1908 2005-05-31 Dan Manthey <dan_manthey@partech.com>
1910 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
1911 now contain newlines, and substituted files must be referenced on
1912 a line alone; the sed scripts to substitute them are now very
1913 different.
1914 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
1915 commands can be put in a sed script portably.
1916 * doc/autoconf.texi (Setting Output Variables): Document above
1917 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
1918 use of multiline substitution.
1919 * tests/torture.at: No longer expect substitution of newline to fail.
1921 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
1923 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
1924 From Ralf Menzel (trivial change).
1926 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
1928 * tests/local.at: Don't attempt to check for negated character
1929 classes in shell scripts. The test was too brittle.
1931 2005-05-25 Stepan Kasal <kasal@ucw.cz>
1933 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
1934 * doc/autoconf.texi (Limitations of Builtins): Document this
1935 limitation.
1937 2005-05-24 Stepan Kasal <kasal@ucw.cz>
1939 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
1940 common code; used in many places in the tree.
1941 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
1942 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
1944 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
1946 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
1947 messages when ac_unique_file is not found.
1948 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
1949 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
1950 commands, for consistency with AC_MSG_ERROR and such.
1952 * bin/autoconf.as: Make more use of "shift 2" in option processing.
1954 * bin/Makefile.am: Merge the two rules for creating scripts.
1956 2005-05-23 Stepan Kasal <kasal@ucw.cz>
1958 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
1959 obsolete; it was never documented.
1960 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
1962 2005-05-20 Stepan Kasal <kasal@ucw.cz>
1964 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
1965 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
1966 (ac_top_builddir): ... this ...
1967 (ac_top_build_prefix): ... to this; the old name is also kept, for
1968 backward compatibility.
1969 (ac_top_builddir_sub): New variable, without the trailing slash,
1970 always nonempty.
1971 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
1972 * doc/autoconf.texi (Configuration Actions): Rename
1973 ac_top_builddir to ac_top_build_prefix.
1974 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
1975 at_top_builddir to at_top_build_prefix.
1976 * lib/autotest/general.m4 (AT_INIT): Likewise.
1978 2005-05-20 Stepan Kasal <kasal@ucw.cz>
1980 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
1981 of confdefs.h .
1983 2005-05-17 Stepan Kasal <kasal@ucw.cz>
1985 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
1986 argument to m4_foreach. I guess it was necessary in the past,
1987 but I think it's a no-op now.
1989 2005-05-17 Stepan Kasal <kasal@ucw.cz>
1991 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
1992 ``cat <<_ACEOF'' commands to one.
1993 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
1994 * lib/autoconf/status.m4: On various places, use expr instead of
1995 ``echo|sed.''
1996 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
1997 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
1998 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
1999 a range.
2000 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2001 the wrong patterns between ``case'' and ``esac.'' The previous
2002 code had false positives.
2004 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
2006 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
2007 as on 2005-05-02.
2008 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
2009 Mention LIBOBJDIR.

2049 2005-05-13 Stepan Kasal <kasal@ucw.cz>
2051 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
2052 check.
2053 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
2054 enough arguments, similarly as in m4_bpatsubsts.
2056 2005-05-12 Stepan Kasal <kasal@ucw.cz>
2058 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
2059 of absolute paths.
2061 2005-05-11 Stepan Kasal <kasal@ucw.cz>
2063 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
2064 for absolute directory names in one loop.
2065 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
2066 abbreviations of --version and --debug.
2068 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
2070 * doc/autoconf.texi (Autoconf Language): Be more precise about
2071 quoting rules. Problems noted by Stepan Kasal.
2072 Also, throughout this document, be more careful about white space.
2073 "blank", "white space", and "space" all have different meanings
2074 and we should be careful to say what we mean.
2076 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
2078 Fix C++ related problems reported by Werner Lemberg.
2079 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
2080 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
2081 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
2082 avoid problems with C++ and throw.
2083 * tests/compile.at: .cpp, not .cc.
2085 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
2087 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2089 * doc/autoconf.texi (Generic Functions): Typos.
2091 2005-05-02 Gary V. Vaughan <gary@gnu.org>
2093 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
2094 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
2095 set by latest automake.
2097 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2099 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
2100 outputs 0 on GNU/Linux these days.
2102 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
2104 * doc/autoconf.texi (Autoconf Language): Add more description
2105 about quoting heuristics.
2106 (Limitations of Builtins): Describe "set -" problems.
2108 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2110 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
2111 not newline.
2113 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
2114 by AC_DEFINE; it was a mistake.
2115 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2117 2005-04-25 Stepan Kasal <kasal@ucw.cz>
2119 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2121 2005-04-22 Stepan Kasal <kasal@ucw.cz>
2123 * doc/autoconf.texi (External Software): Quadrigraphs are not
2124 processed correctly in AS_HELP_STRING; avoid this in the examples.
2125 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2126 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2127 comment and reduce m4_default([foo], []) to [foo].
2128 (m4_strip): Update the explanation.
2130 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2132 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2133 Remove core.conftest.* too; it's generated by Tru64 5.1.
2134 Problem reported by Jennis Pruett.
2135 * lib/autoconf/functions.m4
2136 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2137 Don't bother to remove core files; AC_RUN_IFELSE should do that
2138 for you.
2140 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2142 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
2144 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
2146 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
2147 Report from Horst Wente.
2149 2005-04-15 Stepan Kasal <kasal@ucw.cz>
2151 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
2152 the comment.
2154 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
2156 * doc/autoconf.texi (External Software, Package Options): Add
2157 examples showing how to implement --with-* and --enable-* options.
2159 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2161 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
2162 as well as configure.in. Problem reported by Gregorio Guidi.
2164 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
2166 * doc/autoconf.texi (Particular Functions): Use gnulib's current
2167 pattern for alloca snippet.
2169 2005-04-04 Stepan Kasal <kasal@ucw.cz>
2171 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
2173 2005-04-01 Stepan Kasal <kasal@ucw.cz>

2177 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
2179 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
2180 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
2182 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2184 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
2185 Merge `-z option' as well for the benefit of Solaris link flags. Pass
2186 whole-archive (-zallextract, -zdefaultextract) options in the hope of
2187 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
2188 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
2190 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
2192 * NEWS: The configure command now warns you if you attempt to use
2193 a directory whose name contains a special character like space,
2194 newline, or "\".
2195 * doc/autoconf.texi (Installation Directory Variables): Allow
2196 "," in file names. Do not use \@; it's not a portable regexp.
2197 * bin/Makefile.am (edit): Likewise.
2198 * lib/Makefile.am (edit): Likewise.
2199 * tests/Makefile.am (edit): Likewise.
2200 * tests/semantics.at: Likewise.
2201 * tests/torture.at: Likewise.
2202 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
2203 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
2204 * doc/autoconf.texi (File System Conventions): Warn about
2205 unportable file names.
2206 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
2207 (AC_INIT): Use it.
2208 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
2209 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
2210 ac_pwd, and quote srcdir.
2211 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
2213 * doc/autoconf.texi: Fix some systematic formatting problems.
2214 ".)" needs a following @: if not at the end of a sentence, and
2215 similarly for "!)". "etc." should be preceded by a comma.
2216 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2218 2005-03-22 Bruno Haible <bruno@clisp.org>
2220 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
2221 argument is often called 'build-aux'.
2223 2005-03-07 Stepan Kasal <kasal@ucw.cz>
2225 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
2226 macro AC_TRY_LINK is obsolete.
2227 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
2228 `AC_CONFIG_FILES'.
2230 2005-02-24 Stepan Kasal <kasal@ucw.cz>
2232 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
2233 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
2234 from a Common Lisp's `cl'.
2235 (AC_PROG_CXX): Behave according to the documentation: don't
2236 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
2237 make the variable CCC precious; use `cl.exe', not `cl'.
2239 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2240 Alexandre Duret-Lutz <adl@gnu.org>
2242 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
2243 /dev/null, as "configure" shouldn't read stdin, and this insulates
2244 us from problems (e.g., when testing for "cl"). Also, do this
2245 redirection before invoking "hostname" or "uname", and keep the
2246 original input stream available via...
2247 (AS_ORIGINAL_STDIN_FD): ... this new macro.
2248 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
2249 bother with "</dev/null" since it's now done at the top of
2250 'configure'.
2251 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
2252 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2253 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2254 * doc/autoconf.texi (File Descriptor Macros): New section.
2255 (Printing Messages): Mention it.
2256 * tests/base.at (Input/Output): New test.
2258 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2260 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
2261 newline if neither \c nor -n work, as that would output two
2262 newlines. Prefer -n to \c. Reported by Stepan Kasal.
2264 2005-02-12 Stepan Kasal <kasal@ucw.cz>
2266 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
2267 This causes that any required macros inside will get before the if.
2268 * doc/autoconf.texi (autom4te.cache): A typo.
2270 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
2272 Undo previous change, except keep the change to
2273 lib/autoconf/programs.m4 that replaced grep with shell
2274 pattern-matching. This is because net-snmp configure reads stdin.
2275 Reported by Noah Misch.
2277 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
2279 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
2280 from /dev/null, as "configure" shouldn't read stdin, and this
2281 insulates us from problems (e.g., when testing for "cl").
2282 Suggested by Alexandre Duret-Lutz. Also, do this redirection
2283 before invoking "hostname" or "uname".
2284 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2285 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
2286 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
2287 "</dev/null" since it's now done at the top of 'configure'.
2288 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2289 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2290 Also, replace grep with shell pattern-matching, to save a process.
2292 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
2294 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2295 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
2296 avoid thinking that Allegro Common Lisp's "cl" command is a C++
2297 compiler.

2395 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
2397 Try not to generated lines of unlimited length, as POSIX places a
2398 2047-byte limit on line length of portable text files.
2399 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
2400 Use newline as a separator, not space.

2458 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
2459 Update the long comment explaining it.
2461 m4_require no longer writes an ``is required by'' line to the
2462 execution stack. It contains only one bit of non-redundant
2463 information: that the macro was required, not called. And even
2464 this bit is useless in most situations: have you ever met a macro
2465 which both calls and requires the same macro?
2467 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
2468 (_m4_defun_pro_outer): ... only via this macro, for the outermost

2475 (_m4_require_call): Use it.
2476 * tests/m4sugar.at (m4_require): Expect output without the
2477 ``is required by'' messages.
2479 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2481 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
2482 rather than x for expr.
2484 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
2485 this is safe.
2486 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
2487 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

2508 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2510 * doc/autoconf.texi (Limitations of Builtins): Clarify that

2513 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
2515 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
2516 Warn about newline stripping in `` and $(). Update Solaris
2517 version to 9.
2518 (Limitations of Builtins): Use expr "X...", not expr "x...", as
2519 X insulates us from future changes to Posix.
2520 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
2521 stripping.
2523 2005-01-19 Stepan Kasal <kasal@ucw.cz>

2542 reported by Michael Jennings via Daniel Reed; see
2543 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
2545 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
2547 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

2569 (_m4_divert_n_stack): New macro; the expansion is
2570 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
2571 otherwise.
2572 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
2573 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
2574 stored in _m4_divert_diversion or _m4_divert_dump.
2575 (m4_divert_pop): When the parameter is given, compare the symbolic
2576 name with the last diversion pushed on the stack. Previously, the
2577 current diversion was compared with the numeric value of the
2578 diversion given as the parameter.
2579 (m4_require): If the macro hasn't been expanded yet, call ...
2580 (_m4_require_call): this new macro.

2613 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

2666 * lib/autoconf/status.m4: Quote ``$tmp'' in many places.
2667 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Fix the comment, as traps are

2794 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):

2859 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>

2862 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
2863 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.

2887 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
2888 "char c = '\200';" rather than "char c = 0x80;" as the

2890 overflow on signed char hosts.
2892 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
2893 to -qlanglvl=ansi. We don't want to disable extensions.

3005 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3007 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3008 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3009 (trivial change). Problem and patch reported by Andrew Church in:
3010 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
3012 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

3044 (cvs-update): Fix test for failure. I don't know why it ever
3045 worked...
3047 * doc/autoconf.texi: Update URLs, some of which went stale.

3055 doc/fdl.texi, doc/standards.texi: Sync with master copy.
3057 * NEWS, TODO, configure.ac, bin/autoscan.in,
3058 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
3059 doc/install.texi, lib/Autom4te/Configure_ac.pm,

3065 Use "file name" rather than "filename" or "path",
3066 to be consistent with the terminology of the GNU coding standards.
3068 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3070 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),

3076 This isn't a complete fix but it's an improvement.
3078 * bin/autoconf.as (autom4te_options): New var.
3079 Use it instead of appending to AUTOM4TE, so that we can allow
3080 spaces in the build directory's absolute name.
3081 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3082 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

3110 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3111 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3112 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3113 * lib/autom4te.in (Automake-preselections): Preselect
3114 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3116 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3118 * lib/autom4te.in (Automake-preselections): Preselect
3119 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3120 trace them.

3132 with pdksh, too. Problem reported by Patrick Welche via
3133 Gary V. Vaughan.
3134 * doc/autoconf.texi (Shellology): Note that set -o posix is
3135 useful for pkdsh, too.
3137 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3139 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3140 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3141 Don't fail if ENV or BASH_ENV is readonly.
3142 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,

3153 * doc/autoconf.texi (File System Conventions): Warn about
3154 names like "aux". Problem reported by Eric Blake.
3156 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3157 by zero instead of array size, so that we can use any arithmetic
3158 constant expression (instead of requiring an integer constant
3159 expression). This allows us to test expressions like DBL_MAX <
3160 LDBL_MAX, which didn't conform to the C standard using the old
3161 method.
3162 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3163 now that we can do floating-point tests at compile time.
3165 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
3167 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
3168 and LDBL_EPSILON, as the resulting expression isn't an
3169 integer constant expression and violates the C standard.
3170 Problem reported by Nelson H. F. Beebe. Also, check
3171 for "L" suffix, and check that long double doesn't have
3172 worse range or precision than double, that mixed-mode
3173 arithmetic doesn't generate a diagnostic, that double
3174 constants fit in long double.
3176 2004-06-03 Kevin Ryde <user42@zip.com.au>
3178 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
3179 malloc(0) and realloc(NULL,size).
3181 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
3182 Bob Proulx.

3203 change). Patch reported by Ralf Wildenhues in
3204 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
3206 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
3207 function F exists if the compiler and linker let you compile an
3208 expression like (F != 0). Recent versions of GCC optimize away
3209 the reference to F in that case, since every function address must
3210 be nonzero, so the link succeeds even if F does not exist.
3211 Problem reported by Manu in
3212 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
3214 * doc/autoconf.texi (Systemology): Standardize on the spelling of
3215 "Unix". Many uses changed.
3216 (Limitations of Builtins): Explain better why the ! command isn't
3217 portable.
3219 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
3221 * lib/autom4te.in (Automake-preselections): Preselect
3222 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
3224 2004-05-19 Kevin Ryde <user42@zip.com.au>
3226 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
3227 referencing AC_FUNC_STRERROR_R.
3229 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
3230 note pessimistic assumption when cross compiling.
3232 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
3234 * doc/autoconf.texi (Limitations of Make): Note that BSD make
3235 (until 2004) invoked subcommands with sh -e, contra POSIX.
3236 Reported by Kevin Ryde.
3238 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
3240 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
3241 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
3242 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
3243 `test -f " /usr/bin/grep"', which _always_ failed.
3244 (AC_PROG_SED): Ditto bogus PATH fix.
3245 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
3246 requires that grep correctly supports _multiple_ `-e' options, rather
3247 than stating only that grep should accept `-e'.
3249 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3251 Port to C99, which requires that 'exit' be declared.
3253 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
3254 to ensure that stdlib.h is included.
3255 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
3256 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
3257 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
3258 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
3259 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
3260 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
3261 when using 'exit' in a test; C99 requires that 'exit' be declared.
3263 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
3265 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
3266 now prefers 'grep' implementations that accept -e.
3267 (Limitations of Usual Tools): Describe problems of traditional
3268 egrep and fgrep with long input lines, and of traditional grep
3269 with -e.
3270 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
3271 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
3272 All callers changed. Append /usr/xpg4/bin to the PATH, for
3273 Solaris.
3274 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
3275 the user with complaints about multiple -e options.
3276 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
3277 Define it with AC_PROG_GREP.
3278 * configure.ac (AC_PROG_GREP): Add.
3279 * lib/freeze.mk (GREP): New macro.
3281 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
3283 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
3284 a possible candidate only after all others fail, rather than
3285 consulting it first. This improves backward compatibility by
3286 better reflecting the way shell selection occurred in previous
3287 versions of Autoconf, and should help to avoid triggering latent
3288 problems in other packages, such as the one in Automake where zsh
3289 is not handled robustly:
3290 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
3291 Although it is not Autoconf's responsibility to work around
3292 problems in Automake, it nevertheless makes sense to avoid
3293 introducing unnecessary incompatibilites.
3295 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
3296 Gary V. Vaughan <gary@gnu.org>
3298 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
3299 how deeply nested we are when a suitable tool is found, set the
3300 ac_path_TOOL_found flag.
3301 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
3302 nested we are in this macro. Break out of all 3 nested loops if
3303 ac_path_TOOL_found is set.
3305 2004-04-21 Gary V. Vaughan <gary@gnu.org>
3307 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
3308 of the _AS_PATH_WALK loop too if GNU flavor is found.
3310 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
3312 * doc/autoconf.texi (Limitations of Make): Update documentation
3313 for `$<'. New entry `Long lines', based on a report from Simon
3314 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
3315 paragraph about DJGPP, based on a mail from Richard Dawe.
3317 2004-04-20 Paul Eggert <eggert@twinsun.com>
3319 * tests/c.at (C keywords): Don't assume that GCC supports
3320 "restrict" and "inline", as sufficiently-old GCC versions do not
3321 (also, GCC configured to be in pedantic C89 mode does not).
3322 Problem reported by Sumit Pandya in:
3323 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
3325 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
3326 consider -g to work if it generates warnings when plain compiles
3327 don't. Problem reported by Braden McDaniel in:
3328 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
3330 * doc/autoconf.texi (Slashes): New section, to document a problem
3331 reported by Jim Meyering in:
3332 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
3334 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
3335 linker output files before linking, to work around IRIX 6 linker bug.
3336 Problem reported by Rainer Orth in:
3337 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
3339 2004-04-20 Gary V. Vaughan <gary@gnu.org>
3341 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
3342 best tool so far counter rely on the tool path variable name to
3343 avoid checks for one tool being affected by the results of running
3344 the length check on a previous tool.
3346 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
3347 match expression argument, as different greps have different
3348 regular expression flavours.
3349 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
3350 literals.
3351 (AC_PROG_EGREP): Pass 'EGREP$'.
3352 (AC_PROG_GREP): Pass 'GREP$'.
3354 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
3356 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
3357 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
3359 2004-03-29 Paul Eggert <eggert@twinsun.com>
3361 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
3362 Types, Specific Compiler Characteristics, System Services,
3363 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
3364 etc. consistently instead of 'long', 'short', 'unsigned' etc.
3365 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
3366 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
3367 Likewise.
3368 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
3369 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
3370 AC_TYPE_OFF_T): Likewise.
3371 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
3372 Likewise.
3374 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
3375 pacify libtool 1.5.2. Fix quoting problems in sed command.
3377 2004-03-28 Paul Eggert <eggert@twinsun.com>
3379 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
3380 now defines HAVE_DECL_TZNAME if it is declared, when
3381 HAVE_STRUCT_TM_TM_ZONE is not defined.
3382 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
3383 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
3384 for HAVE_TZNAME.
3386 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
3388 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
3389 superfluous backslashing of quotes (") in sed expressions;
3390 thanks to Paul Eggert.
3392 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
3394 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
3395 Fortran compiler is ifort, also added pghpf; thanks to Nelson
3396 H. F. Beebe for the bug report.
3398 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
3400 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
3401 quoted -cmdline argument in Portland Group compiler (bug
3402 reported by Jeffrey J. Barteet).
3404 2004-03-25 Kevin Ryde <user42@zip.com.au>
3406 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
3407 (Run Time): ... here, where it's now mentioned.
3409 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
3411 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
3412 inherits from language Autoconf-without-aclocal-m4.
3413 (Customizing autom4te): Adjust example; the cache must now be
3414 disabled for language Autoconf-without-aclocal-m4.
3416 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
3417 Nathanael Nerode <neroden@twcny.rr.com>

3425 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
3426 AC_CHECK_TARGET_TOOLS, and warn for future changes
3427 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
3428 AC_CHECK_TOOLS.
3429 (Specifying Names): Document the reason for these future
3430 behavioral changes.
3431 * tests/mktests.sh: Do not generate tests for the
3432 new macros.
3433 * NEWS: Document these changes.
3435 * doc/autoconf.texi: Avoid macros with unbraced arguments,
3436 they make TeX hang up.
3438 2004-03-15 Paul Eggert <eggert@bogus.example.com>
3440 * NEWS: New macro AC_CHECK_ALIGNOF.
3441 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
3442 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
3443 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
3444 vowel.
3445 (AC_CHECK_ALIGNOF): New macro.
3446 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
3447 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
3448 those for sizeof.
3450 2004-03-03 Paul Eggert <eggert@twinsun.com>
3452 * bin/Makefile.am (edit): Don't use $< in a context where
3453 POSIX doesn't require support for it. Use $@.in instead.
3454 Problem reported by Anthony N. Frasso in
3455 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
3456 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
3458 2004-02-23 Gary V. Vaughan <gary@gnu.org>
3460 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
3461 from the next generation of Libtool.
3462 * lib/autom4te.in (Autoreconf-preselections): Ditto.
3464 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
3466 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
3467 is not always thread-safe. Report from Nathanael Nerode.
3469 2004-02-18 Paul Eggert <eggert@twinsun.com>
3471 Fix a dependencies problem, stemming from a Autoconf 2.59 build
3472 problem on QNX reported by Stephen Rasku in
3473 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
3475 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
3476 $(m4sh_m4f_dependencies); this removes a FIXME.
3477 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
3478 (MAINTAINERCLEANFILES): Split into pieces,
3479 one per related section. Add $(srcdir)/wrapper.in.
3481 2004-02-09 Paul Eggert <eggert@twinsun.com>
3483 * doc/autoconf.texi (Setting Output Variables): Emphasize that
3484 AC_SUBST provides no portable way to escape literal newlines.
3486 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
3487 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
3488 Darwin uses -lcrt2.o and there's little point to cataloging all
3489 the system variants. Partial fix reported by Andreas Waechter in:
3490 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
3491 for bug reported by Nelson H. F. Beebe in:

3494 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
3496 * doc/autoconf.texi (AU_DEFUN): Fix English,
3497 suggested by Paul Eggert.
3498 * lib/autoconf/autoupdate.m4: Correct reference to
3499 acobsolete.m4, suggested by Alexandre Duret-Lutz.
3501 2004-02-02 Paolo Bonzini <bonzini@gnu.org>
3503 * bin/autoupdate.in: Define __file__ so that warnings
3504 refer to the correct file.
3505 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
3506 the behavior of the third argument.
3507 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
3508 correctly the behavior of the third argument. Document
3509 what the three macros that AU_DEFUN defines do. Fix
3510 warning message when the third argument includes $0
3511 (reported by Alexandre Duret-Lutz).
3513 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
3514 Eric Sunshine <sunshine@sunshineco.com>
3515 Paul Eggert <eggert@twinsun.com>
3517 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
3518 (AS_INIT): Output shell initialization there. Removed optional
3519 parameter. Expand _AS_SHELL_FN_SPY.
3520 (AS_INIT_WITH_SHELL_FN): Removed.
3521 (_AS_SHELL_FN_SPY): New macro.
3522 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
3523 macros.
3524 (AS_SHELL_SANITIZE): Remove loop to find better shell
3525 and documentation for the parameter.
3526 (_AS_DETECT_BETTER_SHELL): Move it here.
3527 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
3528 (_AS_RUN): Move it here, support testing with eval.
3529 (AS_REQUIRE_SHELL_FN): Require shell functions when
3530 it is used.
3531 (_AS_LINENO_WORKS): Put around braces, we do not
3532 trigger the bash bug anymore.
3533 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
3534 use AS_INIT_WITH_SHELL_FN.
3535 * bin/autoconf.in, tests/wrapper.in: Regenerated.
3537 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
3539 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.
3540 * doc/autoconf.texi: Don't say that the third parameter
3541 is broken.

3543 (AU_DEFUN): Honor the third parameter, create autoupdate
3544 macros with AU_DEFINE.
3545 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
3546 AC_DIR_HEADER): Use AU_DEFUN's third parameter.

3554 * lib/autoconf/status.m4: Remove FIXME.
3555 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
3556 that the macro is not present anymore in the updated
3557 configure.ac.
3558 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
3559 of autoupdate.
3561 2004-01-28 Paul Eggert <eggert@twinsun.com>

3564 copyright years.
3565 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
3566 2003 (except 1997) to the list of copyright years. This undoes
3567 the 2003-05-22 change, which removed the older years from the list.
3568 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
3570 2004-01-27 Gary V. Vaughan <gary@gnu.org>

3574 grep or ggrep program in PATH that accepts as long lines as
3575 possible.
3576 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
3577 AC_PROG_GREP.
3578 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
3579 egrep and fgrep respectively if $GREP -E/-F don't work.
3580 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
3581 _AC_PROG_GREP, and AC_PROG_SED.
3582 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
3583 longest input length accepted by a command.
3584 (AC_PROG_SED): Use it.
3585 * doc/autoconf.texi (Particular Programs): Document the changes.
3586 * NEWS: Updated.
3588 2004-01-27 Paul Eggert <eggert@twinsun.com>
3590 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

3595 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
3596 bin/autoconf.in, config/Makefile.in, config/config.guess,
3597 config/config.sub, config/install-sh, config/mdate-sh,

3610 sources.
3612 2004-01-26 Paul Eggert <eggert@twinsun.com>
3614 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
3615 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
3616 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
3617 not <inttypes.h>. Problem reported by Tim Mooney in
3618 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
3619 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
3620 Likewise.
3622 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
3623 otherwise "make check" fails because it forbids cmp (I guess
3624 because cmp treats files as binary on DOS-like systems).
3626 * tests/mktests.sh: Update copyright date to 2004, since some tests
3627 have changed in 2004.
3629 2004-01-23 Gary V. Vaughan <gary@gnu.org>
3631 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
3632 non-truncating sed or gsed program in PATH.
3633 * tests/acprograms.at: Add it.
3634 * doc/autoconf.texi (Particular Programs): Document it.

3639 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
3640 -std1 disables some useful extensions on Tru64. Problem reported
3641 by N. Lichtmaier in
3642 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
3644 2004-01-14 Paul Eggert <eggert@twinsun.com>
3646 * doc/autoconf.texi (Programming in M4sh): Document that
3647 AS_MKDIR_P succeeds if the destination is a symbolic link
3648 to an existing directory.
3649 (Limitations of Usual Tools): Note that mkdir -p might not
3650 succeed on symlinks to directories.
3652 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
3654 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
3655 * bin/autoheader.in: Grammar fix in message.

3666 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
3668 2004-01-09 Paul Eggert <eggert@twinsun.com>
3670 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
3671 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
3672 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
3673 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
3674 AC_COMPILE_IFELSE, since we now assume our caller invokes
3675 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
3676 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
3677 of AC_RUN_IFELSE; this avoids the warning mentioned above.
3678 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
3680 2004-01-07 Paul Eggert <eggert@twinsun.com>
3682 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
3683 `"'...'"`, as it's confusing (and I suspect it may not work on
3684 some platforms). The code was incorrect anyway, as it assumed
3685 that \$ evaluated to itself in that context. Reported by
3686 Alexandre Duret-Lutz.
3688 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
3690 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

3704 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
3705 autoscan, autoupdate, ifnames): Don't use chmod -w.
3706 * lib/Makefile.am (autom4te.cfg): Likewise.
3707 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
3708 "chmod -w".

3721 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
3723 * Makefile.am (autom4te-update):

3734 srcdir): Likewise.
3735 * doc/autoconf.texi (Limitations of Usual Tools):
3736 Warn against "rm -fr".
3738 2004-01-03 Paul Eggert <eggert@twinsun.com>
3740 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
3741 -c -o might not work. From a suggestion by Kevin Ryde.
3742 (C Compiler, Generating Sources, Limitations
3743 of Usual Tools, Limitations of Make, Making testsuite Scripts):
3744 Don't put '-o' after non-options, as POSIX doesn't allow this.
3745 Mention that cc's name might be gcc or c89 or whatever.
3747 2004-01-04 Kevin Ryde <user42@zip.com.au>
3749 * doc/autoconf.texi: Add various further index entries.
3751 2003-12-29 Paul Eggert <eggert@twinsun.com>
3753 * bin/autoreconf.in (autoreconf_current_directory):
3754 Fix typo: mkdir without umask arg.
3756 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
3758 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
3759 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

3772 * tests/atlocal.in: Store the result here.
3773 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from

3798 functions work.
3799 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
3800 does not work.
3801 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

3820 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

4071 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4072 cache variable instead of $G77 to decide whether to include -O2,

4125 * lib/Autom4te/XFile.pm: Use Errno.
4126 (lock): Ignore ENOLCK errors. Problem reported Andreas Schwab in
4127 <http://mail.gnu.org/archive/html/bug-autoconf/2003-09/msg00141.html>.
4129 2003-09-30 Akim Demaille <akim@epita.fr>
4131 * config/announce-gen (&print_news_deltas): Extracted from...
4132 (&print_changelog_deltas): here.
4133 (&news_file): Rename as...
4134 (@news_file): this.
4136 2003-09-30 Nicolas Joly <njoly@pasteur.fr>
4138 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
4139 have been created when invoking the compiler.

4150 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
4151 Problem reported by Lars J. Aas in
4152 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
4153 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
4154 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
4155 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
4157 2003-09-26 Akim Demaille <akim@epita.fr>
4159 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4160 directory for AC_CONFIG_COMMANDS' first argument exists.
4161 This makes valid the invocation of _AC_SRCPATH that follows.
4162 Reported by Eric Sunshine.
4163 * doc/autoconf.texi (Configuration Commands): Adjust.
4165 2003-09-26 Akim Demaille <akim@epita.fr>
4167 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
4168 Reported by Ralf Corsepius.
4170 2003-09-26 Akim Demaille <akim@epita.fr>
4172 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
4173 arguments.
4174 Actually, use AU_ALIAS.
4175 From Bruno Haible.
4177 2003-09-26 Paul Eggert <eggert@twinsun.com>
4179 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
4180 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
4181 Problem reported by Eric Sunshine in:

4184 2003-09-26 Akim Demaille <akim@epita.fr>
4186 The test suite are sometimes assigning timings incorrectly.
4187 Reported by Henk Krus.
4188 Diagnosed by Nicolas Joly.
4190 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
4191 AT_help_all.
4192 Instead of making AT_help a sequence of assignments to grow
4193 $at_help_all, just make AT_help_all be the growing contents of
4194 $at_help_all, and make a single assignment in...
4195 (AT_INIT): here.
4196 (at_times_skip): Flip the meaning and rename as...
4197 (at_times_p): this.
4198 (AT_INIT): When summarizing the test that ran, remove
4199 $at_times_file after use, and check it is present before trying to
4200 use it.
4202 2003-09-25 Akim Demaille <akim@epita.fr>
4204 Version 2.57d.
4206 * bin/Makefile.am (edit): Handle '@configure_input@'.
4207 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
4208 (ifnames): chmod -w.
4209 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
4210 executables, not bin/ executables! Otherwise all the magic needed
4211 to find non installed files is turned off. This caused a failure
4212 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
4213 as found in its environment (sent by tests/autoreconf): pointing
4214 to bin/autom4te that could not find its files.
4215 * tests/mktests.sh: Force the replacement of generated files, for
4216 the sake of "mv" program that are interactive when overwriting a
4217 -w file.
4218 * config/install-sh: Upgrade from CVS Automake.
4220 2003-09-23 Paul Eggert <eggert@twinsun.com>
4222 * doc/autoconf.texi (Limitations of Builtins): Document test -h
4223 versus test -L issues.
4225 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
4226 Paul Eggert <eggert@twinsun.com>
4228 Trivial change to support GCC's configuration procedure.
4229 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
4230 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
4231 about inconsistency if the preprocessor is set to give errors for
4232 any warning.
4233 * doc/autoconf.texi (C Compiler Characteristics): Document this.
4235 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
4237 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
4238 and XFile.pm from Automake.

4241 2003-09-12 Akim Demaille <akim@epita.fr>
4243 Version 2.57c.
4245 2003-09-12 Akim Demaille <akim@epita.fr>
4247 * config/config.guess, config/config.sub, config/missing,
4248 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
4249 from masters.
4251 2003-09-12 Akim Demaille <akim@epita.fr>
4253 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
4254 not asm/types.h.
4256 2003-09-11 Akim Demaille <akim@epita.fr>
4258 * doc/autoconf.texi (Header Portability): linux/random.h.
4259 From Peter Hendrickson.
4261 2003-09-10 Akim Demaille <akim@epita.fr>
4263 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
4264 willing to edit the output files.
4266 2003-09-10 Akim Demaille <akim@epita.fr>
4268 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
4269 and AC_FC_FREEFORM.
4270 * tests/mktests.sh: Skip AC_FC_SRCEXT.
4271 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
4273 2003-09-09 Akim Demaille <akim@epita.fr>
4275 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
4276 Reported by Gary Vaughan.
4277 * bin/autom4te.in (handle_m4): Likewise.
4279 2003-09-09 Akim Demaille <akim@epita.fr>
4281 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
4282 trailing files.
4284 2003-09-07 Paul Eggert <eggert@twinsun.com>
4286 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
4287 Improve the accuracy of the wording about obsolescence.
4288 From a suggestion by Ian Lance Taylor in
4289 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
4291 2003-09-05 Paul Eggert <eggert@twinsun.com>
4293 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
4294 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
4296 2003-09-04 Akim Demaille <akim@epita.fr>
4298 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
4299 AC_FUNC_WAIT3.
4301 2003-09-04 Akim Demaille <akim@epita.fr>
4303 * bin/autom4te.in: Use &fatal where more appropriate than &error.
4304 (freeze): When exiting, use $exit_code.
4305 * lib/autoconf/fortran.m4: Comment changes.
4307 2003-09-04 Akim Demaille <akim@epita.fr>
4309 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
4311 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
4313 Add support for newer Fortran dialects. The F77 interface is
4314 unchanged, and continues to support Fortran 77. New FC macros
4315 correspond to all the old F77 macros, with output variables FC,
4316 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
4317 available dialect, but older dialects can be specified. There are
4318 new macros AC_FC_SRCEXT to set the source extension, and
4319 AC_FC_FREEFORM to accept free-form source files.
4321 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
4322 New macros.
4323 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.
4324 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), _AC_FORTRAN_ASSERT,

4326 _AC_LANG_PREFIX(Fortran), _AC_FC, AC_LANG_SOURCE(Fortran),

4338 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
4339 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
4340 Rewrite in terms of the above.
4341 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
4342 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
4343 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
4344 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
4346 2003-09-02 Paul Eggert <eggert@twinsun.com>
4348 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
4349 Document problems with timestamp resolution that 'make', 'cp -p', and
4350 'touch -r' have.
4352 2003-08-27 Akim Demaille <akim@epita.fr>
4354 * tests/m4sugar.at (cross_warning): Make sure to enable the
4355 output, so that we can track spurious m4sugar output.
4356 * tests/local.at: Require 2.57.
4357 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
4358 are defaulted by AT_CHECK anyway.
4359 Use AT_CHECK_AUTOM4TE.
4360 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
4361 missing dnl.
4363 2003-08-27 Akim Demaille <akim@epita.fr>
4365 * bin/autoheader.in: Issue the "Using auxiliary..." message only
4366 when -Wobsolete is set.
4367 Set it on by default.
4368 Suggested by Klee Dienes.
4370 2003-08-27 Akim Demaille <akim@epita.fr>

4417 Replace the former...
4418 (m4_warn): Pass the call stack to _m4_warn.
4419 * bin/autom4te.in: Adjust to output the call stack.
4420 * tests/m4sugar.at (m4@&t@_warn): Adjust.
4422 2003-08-22 Akim Demaille <akim@epita.fr>
4424 * lib/Autom4te/Request.pm, lib/Autom4te/C4che.pm: New.
4425 * bin/autom4te.in: Adjust.

4429 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
4430 (&verbose): Remove.

4443 * lib/Autom4te/General.pm: Don't export error: you don't own it.
4445 2003-08-21 Akim Demaille <akim@epita.fr>
4447 First stab at preserving warnings between calls to autom4te,
4448 including when the cache is used.
4450 There are still several issues: (i) there are too many runs of m4
4451 (one for include, one for warnings, and some more), (ii) warnings
4452 spreading on several lines are not handled gracefully, (iii) the
4453 code meant to have the call stack display for errors does not work
4454 (its handling should move from m4 to autom4te).
4456 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
4457 Use them.
4458 (@preselect): Add m4_warn.
4459 ($exit_status): Remove, use $exit_code.
4460 ($help): Use Autom4te::ChannelDefs::usage.
4461 (&handle_m4): No longer define the m4_warnings.
4462 At each run, extract and report the warnings.
4463 Always cache the result, including if the exit status is on
4464 failure, since if nothing changes, we should result in the same
4465 failure, hence we can use the cache.
4466 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
4467 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
4468 Remove.
4469 (m4_warn): Redefine as a do-nothing: it is its invocation that
4470 matters, as warnings are now reported via traces.
4471 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
4472 the contents of m4_warn: make it _call_ m4_warn, so that tracing
4473 the latter reveals calls to the former.
4475 Adjust the tests.
4477 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
4479 2003-08-21 Akim Demaille <akim@epita.fr>
4481 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
4482 Use them.
4484 2003-08-21 Akim Demaille <akim@epita.fr>
4486 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
4487 forward order.
4488 * lib/Autom4te/ChannelDefs.pm: Doc typos.
4489 (&parse_warnings): Accept a list of warning requests.
4490 (&usage): Return a string, not a side effect.
4491 (cross): New warning category.
4493 2003-08-21 Akim Demaille <akim@epita.fr>
4495 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
4496 (&require_configure_ac): Accept an optional directory argument.
4497 ($configure_ac): Remove.
4498 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
4499 (&catfile): Remove.
4500 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
4501 * bin/autoscan.in: Adjust.
4503 2003-08-20 Akim Demaille <akim@epita.fr>
4505 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
4506 Reported by Alexandre Duret-Lutz.
4508 2003-08-20 Akim Demaille <akim@epita.fr>
4510 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
4511 * bin/autom4te: Adjust.
4512 In particular, be Autoconf tools are really silent when properly
4513 working, bind the verbosity of the 'note' channel to $verbose.
4514 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
4515 (&xsystem, &contents): Remove, since they are exported by...
4516 * lib/Autom4te/FileUtils.pm: this.
4517 More perldoc.
4518 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
4519 * lib/Autom4te/FileUtils.pm: here.
4521 2003-08-20 Akim Demaille <akim@epita.fr>
4523 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
4524 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

4553 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
4555 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

4574 2003-08-14 Derek Price <derek@ximbiot.com>
4576 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
4577 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
4578 shorter column three. Add DESCRIPTION to log file content.
4580 2003-08-13 Derek Price <derek@ximbiot.com>
4582 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
4583 output.
4585 2003-08-12 Derek Price <derek@ximbiot.com>
4587 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
4588 (AT_CHECK_NOESCAPE): Move core functionality to...
4589 (_AT_CHECK): ...this new macro.
4591 2003-08-07 Derek Price <derek@ximbiot.com>

4596 2003-07-31 Paul Eggert <eggert@twinsun.com>
4598 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
4599 in Bash 2.01. Problem reported by Brian Gough in
4600 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
4602 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
4604 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
4605 -lcrt1.o, for OS X. (trivial change)
4607 2003-07-07 Paul Eggert <eggert@twinsun.com>
4609 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
4610 inside '#ifndef __cplusplus'. Problem reported by
4611 Bob Friesenhahn.
4613 2003-07-06 Bill Clarke <llib@computer.org>
4615 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
4616 'long', not 'int', for benefit of Sun's recent C++ compilers
4617 (trivial change). See:
4618 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
4619 (This really should be 'intptr_t', not 'long', but that would
4620 take more work.)
4622 2003-06-25 Akim Demaille <akim@epita.fr>
4624 * lib/Makefile.am (autom4te.cfg): Make it read only.
4625 Depend on Makefile since it contains substitutions.
4626 From Paolo Bonzini.
4627 * lib/autom4te.in (args): Add local.at? for Autotest args.
4628 This change was made on autom4te.cfg which is generated.
4629 Reported by Raja R. Harinath.
4631 2003-06-25 Akim Demaille <akim@epita.fr>
4633 * doc/autoconf.texi (Header Portability): sys/mount.h.
4634 From Gareth McCaughan.
4636 2003-06-23 Akim Demaille <akim@epita.fr>
4638 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
4639 not all of them. This fixes 1. the fact that when testing
4640 Autoconf there are many many config.log, 2. the incorrect use of
4641 top_srcdir to find config.log.
4642 Don't mix the detailed output of failed test with the summary of
4643 failures. Rather, append detailed log afterwards.
4645 2003-06-23 Akim Demaille <akim@epita.fr>
4647 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
4648 always run: output config.log on $at_group_log.
4650 2003-06-23 Akim Demaille <akim@epita.fr>
4652 * tests/torture.at (#define header templates): Don't use quotes in
4653 C++ comments as it puzzles Emacs' sh font-lock-mode.
4655 2003-06-23 Akim Demaille <akim@epita.fr>
4657 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
4658 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
4659 * tests/atspecific.m4: Rename as...
4660 * tests/local.at: This.
4661 * tests/suite.at: Move the globals into...
4662 * tests/local.at: here.
4663 * tests/Makefile.am: Adjust.
4664 * doc/autoconf.texi (testsuite Scripts): Adjust.
4666 2003-06-21 Kevin Ryde <user42@zip.com.au>
4668 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
4669 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
4670 ensuring we add -std1 for full-ANSI.
4672 * doc/autoconf.texi (hdrindex): New macro.
4673 Add index entries for portability of various standard header files.
4675 2003-06-20 Akim Demaille <akim@epita.fr>
4677 * configure.ac: Bump to 2.57b.
4679 2003-06-20 Akim Demaille <akim@epita.fr>
4681 Version 2.57a.
4683 2003-06-20 Akim Demaille <akim@epita.fr>
4685 * bin/autom4te.in: Don't rely on $HOME being defined.
4686 Reported by Marc Espie as PR/233.
4688 2003-06-20 Akim Demaille <akim@epita.fr>
4690 * lib/autotest/general.m4: Use at_times_file only if used.
4691 From Nicolas Joly.
4693 2003-06-20 Akim Demaille <akim@epita.fr>
4695 * config/config.guess, config/config.sub, config/elisp-comp,
4696 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
4697 Update from masters.
4699 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
4701 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
4702 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
4703 (TEST_SCRIPT): New diversion.
4704 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
4705 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
4706 (AT_INIT): Support for expected failures.
4708 2003-06-02 Akim Demaille <akim@epita.fr>
4710 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
4711 changes.
4712 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
4713 Autoconf nor Automake.
4714 (&contents): New, from Automake.
4715 PODify.
4717 2003-05-28 Paul Eggert <eggert@twinsun.com>
4719 * NEWS, doc/autoconf.texi (Particular Functions),
4720 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
4721 is the inverse of localtime.
4723 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
4725 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
4726 (handle_exec_errors): New function. Work around $! being
4727 altered by WEXITSTATUS.
4728 (xqx, xsystem): Use handle_exec_errors.
4730 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
4732 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
4733 Do not call `_exit()', simply modify `$?'.
4734 (xsystem): Reset $! before running system, and check it afterward.
4735 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
4736 63 for version mismatches.
4738 2003-05-23 Akim Demaille <akim@epita.fr>
4740 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
4741 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
4742 the middle of a line).
4743 * lib/m4sugar/m4sugar.m4: Likewise.
4744 Remove useless spaces in comments.
4746 2003-05-23 Akim Demaille <akim@epita.fr>
4748 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
4749 exit 63, so that we (or Automake's "missing") can tell the
4750 difference with a plain failure.
4751 * doc/autoconf.texi (Notices): Adjust.
4753 2003-05-23 Akim Demaille <akim@epita.fr>
4755 * Makefile.am, bin/Makefile.am, config/Makefile.am,
4756 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
4757 White spaces cleanup.
4759 2003-05-22 Jim Meyering <jim@meyering.net>
4760 Paul Eggert <eggert@twinsun.com>
4762 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
4763 Remove `#include <stdlib.h>' from the list; we should never
4764 make confdefs.h include <stdlib.h> or <cstdlib>, because the
4765 resulting namespace pollution would cause other tests to fail.
4766 Configure scripts run with some older versions of g++ and HP's
4767 aCC would fail due to such an #include. Problems reported by
4768 Matthew Mueller in <http://bugs.debian.org/120704> and by
4769 Keith Bostic in
4770 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
4771 In the test, use the test declaration before including <stdlib.h>,
4772 as that's closer to how it'll be used.
4774 2003-05-23 Akim Demaille <akim@epita.fr>
4776 * doc/autoconf.texi (Header Portability): ucred.h.
4777 From Ian Redfern.
4779 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
4781 Overhaul Autotest's logging: generate separate log files
4782 in testsuite.dir/NNN/testsuite.log, and append them to
4783 testsuite.log instead of re-running the test verbosely.
4785 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
4786 file descriptor, write 0 to at_status_file instead of setting
4787 at_status=0, initialize some new variables (at_status_file,
4788 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
4789 to rerun the tests, instead append the at_group_log to the
4790 at_suite_log when a test fails.
4791 (AT_SETUP): pipe the test case's output into at_tee_pipe,
4792 with the AS_MESSAGE_LOG_FD redirected to stdout.
4793 (AT_CLEANUP): save the output status in $at_status_file
4794 and restore it, redirect the AS_MESSAGE_LOG_FD back to
4795 its original place.
4796 (AT_CHECK): since tests are run with a redirected stdout,
4797 and used to be re-run in verbose mode, turn some $at_verbose
4798 into echo, and don't redirect the output of testing stdout
4799 and stderr.
4801 * lib/autotest/autoconf.texi (testsuite Scripts): Update
4802 the name of the debugging directory and information about
4803 its contents.
4805 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
4807 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
4808 parameter.
4810 2003-05-22 Akim Demaille <akim@epita.fr>
4812 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4
4813 * lib/autoconf/fortran.m4 lib/autoconf/general.m4
4814 * lib/autoconf/headers.m4 lib/autoconf/oldnames.m4

4830 Whitespace clean up.
4831 Suggested by Jim Meyering.
4833 2003-05-22 Akim Demaille <akim@epita.fr>
4835 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Restore smashed
4836 ' \t' as '\t ' so that Emacs' whitespace.el keep it.
4837 Reported by Jim Meyering.
4839 2003-05-22 Akim Demaille <akim@epita.fr>
4841 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

4843 Typos.
4844 Use '@.' for sentences that ended in a capital letter.
4845 From Art Haas.

4856 it to eval.
4858 2003-05-21 Akim Demaille <akim@epita.fr>
4860 * bin/autoupdate.in ($m4): Fix quotation.

4863 2003-05-19 Paul Eggert <eggert@twinsun.com>
4865 * ChangeLog, ChangeLog.2, THANKS, lib/m4sugar/m4sugar.m4:

4871 * tests/semantics.at (AC_CHECK_HEADERS_OLD,
4872 AC_CHECK_HEADERS_NEW): New tests.
4874 2003-05-17 Akim Demaille <akim@epita.fr>
4876 * lib/autoconf/functions.m4: Use the default includes so that
4877 memcmp be declared before being tested.
4878 Reported by Sander Niemeijer.
4879 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
4880 * doc/autoconf.texi (Default Includes): Document
4881 AC_INCLUDES_DEFAULT.
4883 2003-05-17 Akim Demaille <akim@epita.fr>
4885 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
4886 * doc/autoconf.texi (Obsolete Macros): Adjust.
4887 Reported by Werner LEMBERG and Debian Bug 190886.
4889 2003-05-16 Akim Demaille <akim@epita.fr>
4891 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
4892 user name space clashes.
4893 Reported by Bruno Haible.
4895 2003-05-16 Akim Demaille <akim@epita.fr>
4897 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
4898 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make
4899 them uniform, and more robust to Perl special characters.
4900 Reported by Martin Mokrejs.
4902 2003-05-14 Akim Demaille <akim@epita.fr>
4904 * tests/foreign.at (Libtool): Skip all Libtools pre 1.4.
4906 2003-05-14 Akim Demaille <akim@epita.fr>
4908 * doc/autoconf.texi (Header Portability): X11/extensions/scrnsaver.h,

4913 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Improve the
4914 message.
4915 From Matthias Andree.
4917 2003-05-07 Alexandre Duret-Lutz <adl@gnu.org>
4919 * lib/Autom4te/XFile.pm (lock, truncate): Do not pass @_ to flock
4920 and truncate.
4922 2003-05-06 Akim Demaille <akim@epita.fr>
4924 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
4925 longer updates aclocal.m4 if useless, (ii) if a file m4_included
4926 by aclocal.m4 is changed it might require the importing of another
4927 m4 extension file, i.e., aclocal must be run.
4929 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
4930 (&parse_args): Use --force with aclocal if required and supported.
4931 (&autoreconf_current_directory): Use &run_aclocal.

4935 Lock autom4te's cache.
4937 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
4938 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
4939 argument instead of a file name, so that the request file remains
4940 open during the whole autom4te run.
4941 ($icache_file): New.
4942 (&freeze): Lock the $icache_file.
4944 2003-04-29 Derek Price <derek@ximbiot.com>
4946 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
4947 seperator with m4_append_uniq(). It doesn't work.
4948 (AT_CLEANUP): Add `;' to end of at_help_all.
4949 (AT_INIT): Allow --keywords to be specified more than once. When
4950 grepping $at_help_all for keywords, use the field and keyword
4951 seperators to ensure a complete keyword match. Alter at_prev handling
4952 to support the new --keywords behavior.
4954 2003-04-27 Karl Berry <karl@freefriends.org>
4956 * doc/autoconf.texi: Make the dir entries in the autoconf manual
4957 align better with others. I also made some of the individual
4958 entries on one line, for brevity and to make it easier for me to
4959 sort my dir-example file in the Texinfo distribution :).
4961 2003-04-12 Jim Meyering <jim@meyering.net>
4963 * NEWS: Mention the new macro.
4964 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.
4965 * doc/autoconf.texi (C Compiler): Describe AC_C_RESTRICT.
4966 * tests/c.at: Test AC_C_RESTRICT.

4976 * GNUmakefile (SHELL): Don't assume sh is in /bin/.
4977 From Ilya Zakharevich.
4979 2003-04-08 Akim Demaille <akim@epita.fr>
4981 * doc/autoconf.texi (Particular Headers): Some about sys/socket.h,
4982 net/if.h, stdlib.h.
4984 2003-04-01 Derek Price <derek@ximbiot.com>

4994 2003-04-01 Akim Demaille <akim@epita.fr>
4996 * doc/autoconf.texi (ac, at, ms): Rename these indexes as...
4997 (AC, AT, MS): these.
4998 (shortindexflag, @acindex, @ahindex, @asindex, @atindex, @msindex):
4999 New.
5000 Use them.
5001 * doc/Makefile.am (CLEANFILES): Adjust.
5002 (TEXI2DVI): Make it --batch.
5004 2003-03-31 Derek Price <derek@ximbiot.com>
5006 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
5007 which removed the main loop.
5008 Thanks to Akim Demaille.
5010 2003-03-29 Akim Demaille <akim@epita.fr>
5012 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
5013 that starts a GUI.
5014 From Ilya Zakharevich.
5016 2003-03-29 Akim Demaille <akim@epita.fr>
5018 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
5019 documentation to read is Autoconf's.
5020 Suggested by Paul Eggert.
5022 2003-03-28 Akim Demaille <akim@epita.fr>
5024 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
5025 reading the section "Present But Cannot Be Compiled" when the
5026 header causes problems.
5028 2003-03-28 Akim Demaille <akim@epita.fr>
5030 * tests/torture.at (Configuring subdirectories): Require aclocal
5031 1.4, otherwise the test fails, as it does support configure.ac.
5032 This fixes the "test 40 failed" bug reports.
5034 2003-03-28 Akim Demaille <akim@epita.fr>
5036 * doc/autoconf.texi (C Compiler): `#line' portability.
5037 From Paul Eggert and Nelson H. F. Beebe.
5039 2003-03-27 Derek Price <derek@ximbiot.com>
5041 * lib/autotest/general.m4: Eliminate main loop and reorganize test
5042 layout in order to allow scripting around test groups.
5044 2003-03-27 Derek Price <derek@ximbiot.com>
5046 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
5047 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
5048 use new diversions in preparation for accepting new arguments and
5049 allowing scripting around tests.
5050 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
5052 2003-03-26 Derek Price <derek@ximbiot.com>

5062 2003-03-26 Derek Price <derek@ximbiot.com>
5064 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
5065 sense. Verbosify the diversion definitions comment.
5067 2003-03-26 Derek Price <derek@ximbiot.com>
5069 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
5070 AS_PREPARE.
5072 2003-03-21 Eric Siegerman <eric_97@pobox.com>
5074 * doc/autoconf.texi (Present But Cannot Be Compiled):
5075 Grammar fixes and minor rewording. (trivial change)
5077 2003-03-06 Paul Eggert <eggert@twinsun.com>
5079 Work around a problem noted by Nelson H. F. Beebe with coreutils

5105 (Automake): Automake 1.5+ no longer requires special tools to be
5106 present on the developer's host.
5108 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
5110 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set

5123 to cope with DOS-style absolute paths, when constructing
5124 ${ac_make}.
5126 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
5127 When constructing paths with IFS=:, quote the path. If we're
5128 constructing a DOS-style absolute path, we don't want to split it
5129 on the colon.
5131 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
5132 in description.
5134 2003-02-25 Pavel Roskin <proski@gnu.org>

5151 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
5152 format starting with "-".
5154 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5156 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
5157 is not portable inside Makefile.
5159 2003-02-20 Akim Demaille <akim@epita.fr>
5161 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
5162 compiler says yeah, but preproc says nope, compiler is right.
5163 Conversely, prompt the reader to send a bug report to the
5164 maintainers of the package, not of Autoconf.
5166 2003-02-20 Klee Dienes <kdienes@apple.com>
5168 * bin/autoreconf.in (autoreconf_current_directory): Properly

5174 $ac_prefix_program.
5175 From Larry Jones.
5177 2002-12-23 Paul Eggert <eggert@twinsun.com>
5179 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
5180 innocuous variant befor including <limits.h> or <assert.h>. This
5181 works around a bug reported by Albert Chin: HP-UX 11i
5182 (and earlier versions) have a <limits.h> that declares
5183 gettimeofday and many other functions.
5185 2002-12-03 Paul Eggert <eggert@twinsun.com>
5187 Version 2.57.
5189 * NEWS, configure.ac: Update version.
5191 * doc/fdl.texi: Upgrade to FDL version 1.2.
5193 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
5194 nontrivially in main's body, so that f's external declaration is
5195 not optimized away in AIX. This should fix the bug reported by
5196 Martin Frydl in
5197 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
5199 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
5200 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
5201 defined, to support freestanding compilers. This should fix the
5202 bug reported by Momchil Velkov in
5203 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
5205 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
5206 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

5217 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
5218 \(.*\) match is too long and there is something more to be checked.
5219 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
5221 2002-11-15 Akim Demaille <akim@epita.fr>

5227 * config/move-if-change: Indenting changes.
5228 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
5229 * configure.ac (AM_INIT_AUTOMAKE): here.
5230 Require 1.7.1.
5232 2002-11-14 Akim Demaille <akim@epita.fr>
5234 Version 2.55.
5236 * config/config.guess, config/config.sub, config/install-sh:
5237 Update from masters.
5239 2002-11-14 Akim Demaille <akim@epita.fr>
5241 * Makefile.maint: Sync with Bison, i.e.:
5242 (po-check): Scan .l and .y files instead of the
5243 .c and the .h files that they generate. This fixes the bug
5244 reported by Tim Van Holder in:
5245 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
5246 Look for N_ as well as for _. Try to avoid matching #define for
5247 N_ and _.
5248 From Paul Eggert.
5250 2002-11-14 Akim Demaille <akim@epita.fr>
5252 * doc/autoconf.texi (C Compiler): Compiling several files at once.
5253 From Paul Eggert and Albert Chin-A-Young.
5255 2002-11-14 Akim Demaille <akim@epita.fr>
5257 * doc/autoconf.texi (C Compiler): Solitary backslashes.
5258 From Paul Eggert and Albert Chin-A-Young.
5260 2002-11-14 Kevin Ryde <user42@zip.com.au>
5262 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
5263 than assigning in main, to avoid HP cc +O3 optimizing it away.
5265 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
5267 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
5268 option. Process --recheck after parsing all options. Pass -q
5269 option to configure on --recheck.
5270 (AC_OUTPUT): Pass -q from configure to config.status.
5271 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
5272 arguments to record.
5273 * doc/autoconf.texi (config.status Invocation): Document
5274 config.status -q option.
5276 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
5278 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
5279 Makefile.in if Makefile.am exists.
5280 (output): Strip `.am' from Makefiles. Don't
5281 output AC_CONFIG_FILES if no Makefiles were found.
5283 2002-11-07 Akim Demaille <akim@epita.fr>

5290 2002-11-06 Akim Demaille <akim@epita.fr>
5292 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
5293 declaration in extern "C" too.

5298 * tests/torture.at (Configuring subdirectories): Don't use grep
5299 -w.
5300 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
5301 Reported by Ezra Peisach.
5303 2002-11-05 Akim Demaille <akim@epita.fr>
5305 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
5306 Remove.
5307 We _have_ to stop using the old compatibility scheme that tried to
5308 avoid useless backslashes because Libtool 1.4.3 contains a
5309 AC_DEFINE([error_t], [int],
5310 [Define to a type to use for \`error_t' if it is not
5311 otherwise available.])
5312 We _have_ to quote the single quote and backslashes with \. The
5313 old compatibility scheme saw that ` was backslashed, and therefore
5314 did not quote the single quote. Hence before this patch, Autoconf
5315 was not compatible with Libtool.
5317 2002-11-04 Paul Eggert <eggert@twinsun.com>
5319 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
5320 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
5321 LC_NAME, LC_PAPER, LC_TELEPHONE.

5324 2002-11-04 Akim Demaille <akim@epita.fr>
5326 Version 2.54c.
5328 * Makefile.maint (update, cvs-update, po-update, do-po-update):

5330 * config/texinfo.tex: Update.
5332 2002-11-03 Akim Demaille <akim@epita.fr>
5334 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
5335 from...
5336 (&autoreconf): here.
5337 ($help, $make, &parse_args, &autoreconf_current_directory):
5338 Support -m/--make.
5339 * doc/autoconf.texi (autoreconf Invocation): Adjust.

5355 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
5357 2002-10-31 Akim Demaille <akim@epita.fr>
5359 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
5360 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
5361 Make variable, not a shell variable.
5362 Suggested by Bruno Haible.
5364 2002-10-31 Akim Demaille <akim@epita.fr>
5366 * bin/autom4te.in (load_configuration): Reject #args out of any
5367 language.
5369 2002-10-31 Akim Demaille <akim@epita.fr>
5371 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

5383 Suggested by Tim van Holder.
5385 2002-10-29 Paul Eggert <eggert@twinsun.com>
5387 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
5388 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
5389 Problem reported by Bruno Haible.
5391 2002-10-29 Akim Demaille <akim@epita.fr>
5393 * doc/autoconf.texi (Header Templates): Put also in words what the
5394 pictures says to assist free style readers.
5395 (Customizing autom4te): s/--cache=/--cache /.
5397 2002-10-29 Akim Demaille <akim@epita.fr>
5399 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
5400 sys/wait.h.
5401 sparc_address_test returns void.
5402 Use it with an argument, as prototyped.
5403 From Bruno Haible.
5405 2002-10-29 Akim Demaille <akim@epita.fr>
5407 * doc/autoconf.texi (Subdirectories): Cygnus dirs have

5413 * tests/torture.at (Deep Package): New test.

5419 * bin/autoreconf.in (&parse_args, $help): Support --warnings.
5420 * doc/autoconf.texi (Invoking autom4te): Rename as...

5625 `$ac_configure_args'.

5647 2002-10-22 Akim Demaille <akim@epita.fr>
5649 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
5650 are a few warnings.
5651 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
5652 Quote for Perl '' strings, not "".
5653 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
5654 strings.
5656 2002-10-22 Akim Demaille <akim@epita.fr>
5658 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
5659 characters is a syntax warning now.

5667 Reported by Carlos Velasco.
5669 2002-10-18 Akim Demaille <akim@epita.fr>

5681 2002-10-17 Akim Demaille <akim@epita.fr>
5683 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.

5704 Because of caching, some files that no longer exist and are no
5705 longer required can still cause errors.
5706 Reported by Alexandre Duret-Lutz.
5708 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
5709 to frozen files in @ARGV, as @ARGV must remain being a list of
5710 files. Rather, at M4 call sites, use this...
5711 (&files_to_options): New function.
5712 (&freeze): Use &error.
5713 (&up_to_date): If a file that was included according to the cache
5714 is no longer there, then the output is out dated.
5715 (&main): Don't even check whether a file is up to date is anyway
5716 --force is given.
5717 * tests/tools.at (autom4te cache): New.
5719 2002-10-16 Akim Demaille <akim@epita.fr>
5721 * bin/autoconf.as: Kill dead options.
5722 * bin/autoupdate.in (&parse_args): Kill old options.
5723 * bin/autoreconf.in (&parse_args): Remove dead options.
5724 Factor some code.
5725 (&autoreconf): Report the directories we enter *and leave*, so
5726 that error messages can be easily located, and use GNU Make
5727 format, so that Emacs' compile mode understands us.
5728 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
5729 if some file was changed instead of `print'.
5730 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
5731 (&parse_args): Remove the dead options.
5732 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

5761 2002-10-11 Akim Demaille <akim@epita.fr>
5763 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
5764 file name to enable parallel executions.
5765 From Sam Varshavchik.
5767 2002-10-08 Akim Demaille <akim@epita.fr>
5769 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
5770 aclocal invocation, as Gettext macros might not be visible to
5771 aclocal.
5772 Instead of blindly running autopoint, scan configure.ac (not the
5773 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
5774 Reported by Paul D. Smith.
5776 2002-10-08 Paul Eggert <eggert@twinsun.com>
5778 Work around problems found when POSIXLY_CORRECT=1 is set.
5779 None of this seems to have anything to do with POSIX, really,
5780 but it's how Perl getopt works.
5781 * bin/autom4te.in (parse_args): Configure GetOpt with
5782 "permute", too.
5783 * doc/autoconf.texi (Invoking autom4te):
5784 --warning -> --warnings.
5785 * lib/autom4te.in: --warning -> --warnings.

5804 2002-09-28 Akim Demaille <akim@epita.fr>
5806 * tests/torture.at (Configuring subdirectories): Be robust to
5807 users who use config.site to require for a cache: in this case,
5808 the two last configure runs, using two different sets of
5809 arguments, trigger a legitimate error.
5811 2002-09-28 Akim Demaille <akim@epita.fr>
5813 * tests/m4sh.at (Functions Support, Functions and return Support):
5814 New.

5827 (tm_zone): Move their rules to...
5828 * lib/autoconf/types.m4: here, using AN_ macros.
5829 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
5830 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
5831 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
5832 * lib/autoconf/programs.m4: here.
5833 * lib/freeze.mk (ETAGS_FOR_M4, ETAGS_FOR_M4SUGAR)

5844 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
5845 (.m4.m4f): Don't pass --prepend-include, since that's done by
5846 tests/autom4te itself.
5847 * lib/autoscan/Makefile.am: Include freeze.mk.
5848 (autoscan.list): New target --this file is no longer a source.
5849 (autoscan.pre): New file.
5851 2002-09-28 Akim Demaille <akim@epita.fr>
5853 * bin/autoscan.in (@kinds): Make them singular.
5854 Adjust all uses.
5855 (&init_tables): When --debug, report the list of rules to ease
5856 tracking changes in autoscan.list.
5857 * lib/autoscan/autoscan.list (function): Strip comments, sort.
5859 2002-09-28 Akim Demaille <akim@epita.fr>

5870 * lib/autoscan/identifiers, lib/autoscan/makevars,
5871 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
5872 `functions' line is now prefixed with `function:'.
5873 * bin/autoscan.in (&init_tables): Adjust.
5875 2002-09-28 Akim Demaille <akim@epita.fr>
5877 From now on, autoscan files must always map a macro name to a
5878 word: there is no `default' macro for autoscan.
5880 * bin/autoscan.in (&init_tables): Reject entries with no macro at
5881 all.
5882 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
5883 explicit.
5885 2002-09-28 Akim Demaille <akim@epita.fr>
5887 * bin/autoscan.in (%c_keywords): Remove.
5888 (&used): Keep only track of the words we might be interested in.

5919 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
5920 Reported by Ralf Corsepius.
5921 * doc/autoconf.texi (autoreconf Invocation): Likewise.
5923 2002-09-26 Akim Demaille <akim@epita.fr>
5925 Single suffix rules and seperated dependencies are not portable.
5927 * doc/autoconf.texi (Installation Directory Variables): Update.
5928 (Limitations of Make): Some about `Single Suffix Rules and

5947 2002-09-16 Akim Demaille <akim@epita.fr>
5949 i960 compilers create `b.out' files by default.
5950 Reported by Ralf Corsepius.
5952 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.

5971 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest

5973 Suggested by Guido Draheim.
5975 2002-09-13 Akim Demaille <akim@epita.fr>
5977 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
5978 (chdir_init) might hang when stat'ing mounted directories.
5979 Reported by Vance Shipley.
5981 2002-09-12 Akim Demaille <akim@epita.fr>
5983 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
5984 the lists.
5986 2002-09-12 Akim Demaille <akim@epita.fr>
5988 * doc/autoconf.texi (Defining Symbols): Present two different
5989 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

5994 * doc/autoconf.texi: Review grammar and punctuation.

5999 grammatical typos.
6000 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6001 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6002 is obsolescent.
6004 2002-09-11 Akim Demaille <akim@epita.fr>
6006 * doc/autoconf.texi (Questions): Rename as...
6007 (FAQ): this.

6022 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6023 `duplicates', since the algorithm was too naive and could keep
6024 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6025 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6026 Reported by Ralf Corsepius.
6027 * tests/torture.at (Configuring subdirectories): Exercise these
6028 cases.
6030 2002-09-09 Akim Demaille <akim@epita.fr>

6033 looking for a replacement file.
6034 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6035 directory is relative.
6036 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6037 directory definition.
6038 Reported by Andreas Schwab and Jim Meyering.
6040 2002-09-06 Akim Demaille <akim@epita.fr>

6043 precious variables are.
6044 Suggested by Pontus Skoeld.
6046 2002-09-05 Akim Demaille <akim@epita.fr>
6048 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6049 (ifnames, autoscan, autom4te): Since we don't only depend on
6050 configure.ac variables (such as VERSION etc.), but also on prefix
6051 and so forth, depend on Makefile, not configure.ac.
6052 Reported by Alexandre Duret-Lutz.
6053 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6055 2002-09-05 Kevin Ryde <user42@zip.com.au>
6057 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6058 doesn't seem to be confined to ia64, just say "some versions".
6060 2002-09-04 Akim Demaille <akim@epita.fr>
6062 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by

6075 * configure.ac: Bump to 2.53d.
6076 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6077 as of today, on Automake's team suggestion.
6079 2002-09-03 Akim Demaille <akim@epita.fr>
6081 Version 2.53c.
6083 2002-09-02 Akim Demaille <akim@epita.fr>
6085 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6086 SITE_MACRO_DIR.
6087 * configure.ac: Disable SITE_MACRO_DIR.
6089 2002-09-02 Jim Meyering <meyering@lucent.com>
6091 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6092 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6093 Also, tweak grammar: s/make sure to/be sure to/.
6095 2002-09-02 Paul Eggert <eggert@twinsun.com>
6097 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6098 directory names are generally preferable to physical names.
6100 2002-09-02 Akim Demaille <akim@epita.fr>
6102 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6103 Reported by Raja R. Harinath.
6104 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6105 * bin/autoupdate.in: Use error instead of die.
6107 2002-09-01 Paul Eggert <eggert@twinsun.com>
6109 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6110 ordinary shell concatenation rather than echo+tr+sed command that
6111 runs afoul of a long-line-related sed bug in Solaris 8.
6113 * bin/autoheader.in (parse_args): --warning -> --warnings.
6115 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6116 stdout, as traditional "ls" does.
6117 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6118 _AC_COMPILER_EXEEXT_O): Likewise.
6119 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6121 * bin/autoconf.as: Add --prepend-include option. This patch was
6122 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6123 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6125 * bin/autoconf.in, configure: Regenerate.
6127 * doc/autoconf.texi (Special Shell Variables): Mention
6128 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6130 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6131 MAILPATH and set PS1, PS2, PS4 to default values, to work
6132 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6133 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6134 the Autoconf documentation specifies; fall back to "unset" only if
6135 this fails. Use a shell for-loop for this rather than an m4 loop,
6136 to shorten the output script.
6138 2002-08-30 Paul Eggert <eggert@twinsun.com>
6140 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6141 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6142 for the CDPATH problem. Document PWD.
6143 (Limitations of Builtins): Document the problem that "cd $foo" and
6144 "ls $foo" may refer to different directories in shells conforming
6145 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6146 example, since the old example is now out of date.
6148 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6149 FOO" and "ls FOO" talk about different directories; this catches
6150 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6151 spaghetti.
6153 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6154 of rolling our own unset.
6155 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6156 in practice we needn't worry about CDPATH if unset doesn't work.
6158 * Makefile.in, aclocal.m4, bin/Makefile.in,
6159 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6160 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6161 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6162 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6163 tests/Makefile.in: Regenerate with Automake 1.6.3.
6165 * config/config.guess, config/config.sub, config/mkinstalldirs:
6166 Update.
6168 * configure: Regenerate with self.
6170 2002-08-30 Kevin Ryde <user42@zip.com.au>
6172 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
6173 default output.
6175 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
6177 * bin/autom4te.in (Request::load): Correctly test for "do" read
6178 failure.
6180 2002-08-29 Akim Demaille <akim@epita.fr>
6182 * lib/Autom4te/General.pm (&xqx): New.
6183 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
6184 hand, which is not portable.
6185 (&error): New.
6186 * bin/autom4te.in: Use them.
6187 Use &error instead of die.
6188 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
6189 Adjust.
6191 2002-08-17 Paul Eggert <eggert@twinsun.com>
6193 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
6194 default list of compilers to try, since it was long ago superseded
6195 by the ksh fc builtin. Suggested by Steven G. Johnson.
6197 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
6199 * doc/autoconf.texi (Invoking autom4te): End the option table,
6200 fixing a bug introduced by the previous patch.
6201 (Limitations of Make): Add a 'target lookup' subentry in the
6202 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
6204 2002-07-29 Mark D. Roth <roth@feep.net>
6206 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
6207 options and use $AUTOM4TE_PATH.
6208 * doc/autoconf.texi: Remove documentation of autom4te
6209 --include-envvar and --site-macro-subdir options and document
6210 use of $AUTOM4TE_PATH.
6211 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
6212 arguments from each language section.
6214 2002-07-29 Paul Eggert <eggert@twinsun.com>
6216 * doc/install.texi: Include copyright symbol in copyright notice.
6218 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
6219 Replace with:
6220 (AM_MAKEINFOFLAGS): New macro.
6221 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
6222 * Makefile.am (INSTALL): Use the new macros.
6223 Use -o rather than --output, since "missing" does not grok --output.
6225 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6227 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
6228 comments do not always work. Never trust the exit status of
6229 `make -k'.
6231 2002-07-24 Kevin Ryde <user42@zip.com.au>
6233 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
6234 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
6236 2002-07-23 Paul Eggert <eggert@twinsun.com>
6238 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
6239 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
6240 apparently treats PATH="nonexistent" as if it contained ".".
6241 Bug reported by Stefan `Sec' Zehl.
6243 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
6245 * doc/autoconf.texi (Limitations of Make): Mention the special
6246 handling of the obj/ directory by BSD make.

6266 2002-07-18 Akim Demaille <akim@epita.fr>
6268 * config/config.guess, config/config.sub: Update.
6270 2002-07-18 Akim Demaille <akim@epita.fr>

6363 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
6364 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
6365 so that Emacs setups GNU style for perl-mode and cperl-mode.
6367 2002-06-27 Paul Eggert <eggert@twinsun.com>
6369 * config/install-sh: Quote $src. Prefer || to test's -o option,
6370 as per "Limitations of Builtins".
6371 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
6372 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6374 * tests/mktests.sh: Use grep instead of fgrep, as per
6375 "Limitations of Builtins".
6377 2002-06-15 Paul Eggert <eggert@twinsun.com>
6379 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
6380 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
6381 so that we consistently test the just-built programs.
6382 * tests/wrappl.as: Likewise.
6384 2002-06-12 Paul Eggert <eggert@twinsun.com>
6386 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
6387 name, so that symlinks to 'autoconf' work properly. Bug reported
6388 by Bruno Haible.
6389 * bin/autoheader.in (AUTOM4TE): Likewise.
6390 * bin/autoreconf.in (autoconf, autoheader): Likewise.
6391 * bin/autoscan.in (autom4te): Likewise.
6392 * bin/autoupdate.in (autom4te): Likewise.
6394 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
6395 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
6396 on Solaris 2.5.1.
6398 2002-06-11 Andreas Schwab <schwab@suse.de>
6400 * doc/autoconf.texi: Add more dir entries.
6402 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
6404 * bin/autom4te.in ($cache): Don't define using `$me', the name
6405 of the cache should not depend on the name under which autom4te
6406 was installed.
6408 2002-06-07 Akim Demaille <akim@epita.fr>
6410 * tests/tools.at (autoconf: forbidden tokens, basic)
6411 (autoconf: forbidden tokens, exceptions): Adjust to the change of
6412 words in autom4te.in.
6414 2002-06-07 Peter Eisentraut <peter_e@gmx.net>

6417 _AC_LANG_PROGRAM_C_F77_HOOKS.
6419 2002-06-07 Akim Demaille <akim@epita.fr>
6421 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
6422 rename as...
6423 (AC_REPLACE_FNMATCH): this.
6424 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
6425 AC_FUNC_FNMATCH_GNU.
6427 2002-06-07 Akim Demaille <akim@epita.fr>
6429 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the

6432 2002-06-07 Akim Demaille <akim@epita.fr>
6434 * bin/autom4te.in (warn_forbidden): When rejecting a token,
6435 suggest m4_pattern_allow.
6436 Suggested by Adam J. Richter.
6438 2002-06-07 Akim Demaille <akim@epita.fr>
6440 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
6441 ac_config_libobj_dir.
6442 (AC_CONFIG_LIBOBJ_DIR): New.
6443 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

6454 2002-06-06 Paul Eggert <eggert@twinsun.com>
6456 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
6457 if ln doesn't work.
6458 * NEWS: Likewise.
6459 * doc/autoconf.texi (Configuration Links): Likewise.
6460 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
6462 2002-06-05 Paul Eggert <eggert@twinsun.com>
6464 * config/config.guess, config/config.sub, config/texinfo.tex:
6465 Update from masters.
6467 2002-05-29 Paul Eggert <eggert@twinsun.com>

6480 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
6482 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
6483 * doc/autoconf.texi (Particular Programs): Document them.

6490 * NEWS, doc/autoconf.texi (Particular Types): Document it.
6491 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
6492 instead of AC_MBSTATE_T, which never existed.
6494 2002-05-23 Akim Demaille <akim@epita.fr>
6496 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
6497 version of Autoconf that is discussed.
6499 2002-05-22 Paul Eggert <eggert@twinsun.com>
6501 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
6502 from the default list of compilers to try. Suggested by
6503 Kate Hedstrom.
6504 * NEWS: Document the above.
6505 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
6507 2002-05-17 Paul Eggert <eggert@twinsun.com>
6509 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
6510 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
6511 This improves on an earlier suggestion by H. Peter Anvin.
6513 2002-05-16 Paul Eggert <eggert@twinsun.com>
6515 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
6516 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
6517 Both macros now accept an optional source-dir arg.
6518 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
6520 * NEWS: Document this.
6521 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
6523 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
6524 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
6525 not for GNU extensions; this undoes part of the 2000-11-03 change,
6526 reverting to 2.13-compatible behavior.
6527 Add new optional argument DIR.
6528 (AC_FUNC_FNMATCH_GNU): New macro.
6530 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
6532 2002-05-08 Paul Eggert <eggert@twinsun.com>
6534 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
6535 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
6536 and it causes a 'test' syntax error if it fails.
6537 Bug reported by Stephen Gildea.
6539 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6540 If prototypes are supported, use them to check this at compile-time,
6541 instead of trying to check it at run-time. If we must do a run-time
6542 check, assume that setvbuf is standard when cross-compiling, as
6543 nonstandard setvbuf occurs only on ancient and unlikely hosts.
6544 Bug reported by Paul D. Smith.
6546 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
6547 argument specifying location of getloadavg.c. This removes a
6548 FIXME. This idea was taken from Jim Meyering's implementation in
6549 textutils.
6550 * doc/autoconf.texi (Particular Functions): Document this.
6551 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
6552 that's what the code does; this fixes a bug reported by
6553 Paul D. Smith.
6555 2002-05-03 Akim Demaille <akim@epita.fr>
6557 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
6558 autopoint instead of gettextize.
6559 ($uses_alocal): Rename as...
6560 ($uses_aclocal): this.
6561 * doc/autoconf.texi (autoreconf Invocation): Adjust.
6562 Suggested by Bruno Haible.
6564 2002-05-03 Akim Demaille <akim@epita.fr>
6566 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
6568 2002-04-29 Paul Eggert <eggert@twinsun.com>
6570 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
6571 files to be 1 second older; just set them to be the same time.
6572 Also, sleep 1 second after the first aclocal, to work around
6573 problems with sub-second time stamps on the input files.
6575 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
6577 * doc/autoconf.texi: Mention "set -e -x" lossage
6578 under node "Limitations of Builtins".
6580 2002-04-29 Akim Demaille <akim@epita.fr>
6582 * doc/install.texi: Better wording for setting variables when
6583 running configure.
6584 From Christian Cornelssen.
6586 2002-04-29 Akim Demaille <akim@epita.fr>
6588 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
6589 of lack of $LINENO support, then the test will compare the $LINENO
6590 in testsuite vs. the lineno in the test file. This is wrong, of
6591 course.
6592 Be sure to protect it.
6593 Reported by Patrick Welche.
6595 2002-04-25 Akim Demaille <akim@epita.fr>
6597 * doc/autoconf.texi (Obsolete Macros): Typo.
6598 Reported by Vladimir Volovich.
6600 2002-04-25 Akim Demaille <akim@epita.fr>
6602 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
6603 than some of the input files, hence, on the second run of aclocal,
6604 if some of its input are younger, make them older.
6605 Suggested by Paul Eggert.
6607 2002-04-25 Akim Demaille <akim@epita.fr>
6609 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
6610 Thanks to Paul Eggert.
6612 2002-04-25 Akim Demaille <akim@epita.fr>
6614 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
6615 and ac_subst_vars be sh variables containing the list of
6616 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
6617 DEFAULT diversion.
6618 (_AC_INIT_PREPARE): Use them to log them.
6619 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
6620 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
6621 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
6622 _AC_SUBST_FILES and _AC_SUBST_VARS.
6623 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
6625 2002-04-24 Akim Demaille <akim@epita.fr>
6627 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
6628 autoheader, so that automake does not complain about a missing
6629 config.h.in that was to be created.
6631 2002-04-23 Akim Demaille <akim@epita.fr>
6633 * bin/autoheader.in (parse_args): --warning takes an argument.
6634 Fixes PR/220.
6636 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
6638 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
6639 and bb.out when cleaning up.
6641 2002-04-22 Akim Demaille <akim@epita.fr>
6643 Version 2.53a.
6645 2002-04-22 Akim Demaille <akim@epita.fr>
6647 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
6649 2002-04-22 Akim Demaille <akim@epita.fr>
6651 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
6652 comma.
6653 Reported by Gregory Giannoni.
6655 2002-04-22 Akim Demaille <akim@epita.fr>
6657 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
6658 Fixes false failures on Darwin.
6660 2002-04-21 Paul Eggert <eggert@twinsun.com>
6662 * TODO, bin/autoupdate.in, doc/autoconf.texi,

6664 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,
6665 tests/tools.at: Minor spelling and grammar fixes.
6667 2002-04-20 Paul Eggert <eggert@twinsun.com>
6669 * doc/autoconf.texi (Shell Substitutions): Fix typos in yesterday's
6670 ZSH_VERSION fixes. Bug reported by Raja R Harinath.

6682 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
6683 Minor spelling and grammar fixes.
6685 * doc/autoconf.texi: Follow the outline suggested in the GNU
6686 Sample Texts sections of the Texinfo 4.2 manual. Most
6687 importantly, this makes sure that the copyright notices appear in
6688 all output formats. You probably need Texinfo 4.2 to generate
6689 the manual now.
6691 Fix some bugs when using "$@" when there might be zero positional
6692 arguments in cases where this matters.
6694 * bin/autoconf.as: Rewrite so that the problem does not come up.

6709 Use Zsh alias to work around problem.
6710 * tests/atgeneral.m4 (AT_INIT): Likewise.
6712 * tests/c.at: We can't have zero arguments, so remove workaround
6713 that is not portable to Zsh.
6715 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
6717 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
6718 from aclocal.m4 too.
6720 2002-04-12 Akim Demaille <akim@epita.fr>
6722 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
6724 2002-04-10 Akim Demaille <akim@epita.fr>
6726 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
6727 workaround for ${1+"$@"}.
6728 * doc/autoconf.texi (Shell Substitutions): Explain it.
6729 From Oliver Kiddle and Peter Stephenson.
6731 Have M4sh perform minimal shell sanitizing.
6733 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
6734 part into...
6735 (_AS_PREPARE): this new macro.
6736 (AS_PREPARE): New.
6737 (AS_INIT): Invoke AS_SHELL_SANITIZE.
6738 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
6740 Adjust Autoconf and Autotest.
6742 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
6743 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
6744 * lib/autotest/general.m4 (AT_INIT): Likewise.
6745 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
6746 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
6747 AS_SHELL_SANITIZE.
6749 Use this M4sh to generate Autoconf's shell scripts.
6751 * tests/wrapsh.as: New, precursor of wrapsh.in.
6752 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
6753 on Autotest and M4sh.
6754 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
6755 (wrapsh.in): New target.
6756 * bin/autoconf.as: New, precursor of autoconf.in.
6757 (autoconf.in): New target.
6759 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>
6761 * doc/autoconf.texi (Limitations of Make): Mention the issue
6762 with indented comments in rules.
6764 2002-04-09 Andreas Schwab <schwab@suse.de>
6766 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
6767 ac_top_builddir when setting ac_abs_top_builddir.
6769 2002-04-06 Kevin Ryde <user42@zip.com.au>
6771 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
6772 (Portable Shell): Cross reference to Systemology.
6774 2002-04-05 Akim Demaille <akim@epita.fr>
6776 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
6777 directories when descending in a SUBDIRS.
6778 Reported by Ezra Peisach.
6780 2002-04-04 Andreas Schwab <schwab@suse.de>
6782 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
6783 contains no literal separators.
6785 2002-04-03 Akim Demaille <akim@epita.fr>
6787 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
6788 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
6789 Use dnl, not the KILL diversion.
6790 Extracted from...
6791 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
6792 (AC_CONFIG_LINKS): here.
6793 Adjust.
6794 Don't use the KILL diversion, as it kills spurious output, which
6795 results in failures being hidden.
6796 Use m4_defn where appropriate.
6797 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
6798 after the second argument.
6799 Use m4_defn.
6800 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
6801 syntax, as it is provided by M4sugar.
6802 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
6804 2002-04-03 Andreas Schwab <schwab@suse.de>
6806 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
6807 expanded if $# <= 2.
6809 * bin/autoreconf.in (autoreconf): Run automake after rerunning
6810 aclocal.
6812 2002-04-03 Akim Demaille <akim@epita.fr>
6814 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
6815 (_AC_COMPILER_EXEEXT_REJECT): New.
6816 Also recognize *.bb and *.bbg as compilation byproducts.
6817 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
6818 (_AC_COMPILER_OBJEXT): Use them.
6819 Fixes Debian #138666.
6821 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
6823 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
6825 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
6826 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
6827 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
6828 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
6829 (AC_C_CONST): Same.
6830 (AC_C_INLINE): Same.
6831 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
6832 * doc/autoconf.texi, NEWS: Document.
6833 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
6834 AC_C_CROSS.
6836 2002-04-02 Akim Demaille <akim@epita.fr>
6838 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke
6839 _AS_MKDIR_P_PREPARE.
6841 2002-03-28 Kevin Ryde <user42@zip.com.au>
6843 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
6844 to avoid versions of HP C which don't allow that.
6846 2002-03-27 Paul Eggert <eggert@twinsun.com>
6848 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
6849 (AS_SHELL_SANITIZE): Invoke it.
6850 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
6852 2002-03-26 Akim Demaille <akim@epita.fr>
6854 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
6856 2002-03-26 Akim Demaille <akim@epita.fr>
6858 * doc/autoconf.texi (Introduction): The GNATS base moved.
6860 2002-03-25 Paul Eggert <eggert@twinsun.com>
6862 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
6863 as POSIX requires, as it doesn't work with Zsh.
6864 * doc/autoconf.texi (Assignments): Document the problem.
6866 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6868 * doc/autoconf.texi (Limitations of Make): Mention more issue
6869 about VPATH, overriding of macros in sub-makes, and handling of
6870 SHELL.
6872 2002-03-21 Paul Eggert <eggert@twinsun.com>
6874 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
6875 problem with here-document buffer boundaries.
6877 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
6878 when reinvoking the shell, to work around problems with installers
6879 who put strange things like "cd" commands in their environments.
6881 2002-03-19 Akim Demaille <akim@epita.fr>
6883 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
6884 From Aaron Ucko.
6886 2002-03-19 Akim Demaille <akim@epita.fr>
6888 * bin/autoscan.in (scan_file): Specify the location in `&used'
6889 invocations.
6890 From Nicolas Joly.
6892 2002-03-19 Akim Demaille <akim@epita.fr>
6894 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
6895 From Nishio Futoshi.
6897 2002-03-19 Akim Demaille <akim@epita.fr>
6899 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
6901 2002-03-18 Paul Eggert <eggert@twinsun.com>
6903 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
6904 (Limitations of Usual Tools): Add mkdir section.
6906 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
6907 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
6908 back on AS_DIRNAME to compute prefixes otherwise; this is
6909 roughly what mkinstalldirs does. That way, we need not have
6910 our own filename disassembler. The old disassembler did not
6911 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
6913 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
6914 Create at_test_all by a series of assignments,
6915 not by a single assignment of a long string. The latter causes ksh
6916 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
6917 presumably because of a buffer overrun.
6919 2002-03-14 Paul Eggert <eggert@twinsun.com>
6921 * lib/autotest/general.m4 (at_times_skip):
6922 Renamed from at_times. Now a boolean.
6923 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
6924 says 'times: not found'.
6926 2002-03-14 Akim Demaille <akim@epita.fr>
6928 * bin/autoreconf.in (&study_gettextize): New.
6929 (&autoreconf): Handle newest gettextize.
6930 Rerun aclocal if needed.
6931 Suggested by Andreas Schwab.
6933 2002-03-13 Akim Demaille <akim@epita.fr>
6935 * doc/autoconf.texi (Special Shell Variables): More about IFS.
6937 2002-03-13 Akim Demaille <akim@epita.fr>
6939 * doc/autoconf.texi (Header Portability): New.
6940 Add information about stdint.h and inttypes.h from Paul Eggert.
6942 2002-03-13 Akim Demaille <akim@epita.fr>
6944 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
6945 -p'.
6946 From Bob Proulx.
6948 2002-03-12 Akim Demaille <akim@epita.fr>
6950 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
6951 m4_require.
6953 2002-03-11 Andreas Schwab <schwab@suse.de>
6955 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
6956 does not do it if --with-lispdir is given.
6958 2002-03-08 Akim Demaille <akim@epita.fr>
6960 Version 2.53.
6962 2002-03-08 Akim Demaille <akim@epita.fr>
6964 * doc/autoconf.texi (Subdirectories): Clarify that the
6965 subdirectory should exist.
6967 2002-03-08 Akim Demaille <akim@epita.fr>
6969 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
6971 2002-03-08 Akim Demaille <akim@epita.fr>
6973 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
6974 aliases the actual variables, and modifications of the former
6975 affect the latter.
6977 2002-03-08 Akim Demaille <akim@epita.fr>
6979 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
6980 because of C-c: have m4 output in tmp files, then mv them.
6982 2002-03-08 Akim Demaille <akim@epita.fr>
6984 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
6985 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
6986 * bin/ifnames.in: Copyright update.
6988 2002-03-08 Akim Demaille <akim@epita.fr>
6990 * doc/autoconf.texi (Invoking autom4te): New.
6992 2002-03-05 Akim Demaille <akim@epita.fr>
6994 * doc/autoconf.texi (Specifying Names): Clarification suggested by
6995 Kevin Ryde.
6997 2002-03-05 Akim Demaille <akim@epita.fr>
6999 Version 2.52i.
7001 2002-03-04 Akim Demaille <akim@epita.fr>
7003 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
7004 * lib/autoconf/general.m4 (AC_INIT): More informative error
7005 message for LIBOBJ.
7007 2002-03-04 Akim Demaille <akim@epita.fr>
7009 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
7010 parallel builds.
7012 2002-03-04 Akim Demaille <akim@epita.fr>
7014 * doc/autoconf.texi (Transforming Names): Equality between target
7015 and host is irrelevant.
7016 (Specifying Names, Canonicalizing): Remove all references to the
7017 backward compatibility hooks. Rather, collect them all into...
7018 (Hosts and Cross-Compilation): this new section.
7019 * doc/install.texi (System Type): Ditto.
7020 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7021 that `--host' implies cross-compilation.
7023 2002-03-04 Akim Demaille <akim@epita.fr>
7025 * doc/autoconf.texi (Evaluation Macros): New.
7026 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7027 useless.
7028 (_m4_foreach): Define the variant with immediate evaluation so
7029 that it contains exactly the items, not an expression which
7030 evaluation is the current item.
7031 (m4_re_string, m4_re_word): Don't over quote them.
7033 2002-03-04 Akim Demaille <akim@epita.fr>
7035 Instead of having stacking `shift's evaluated at the end, let
7036 `foreach' loops immediately evaluate them.
7038 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7039 $*. This is the n-th time I change my mind, but hopefully this is
7040 the last...
7041 (m4_lquote): New.
7042 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7043 efficient.
7044 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7045 it was only a hack for m4_text_wrap.
7046 (m4_car2): Remove, replaced by...
7047 (m4_cdr): New.
7048 (_m4_foreach): Adjust.
7049 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use

7072 message to be sent.
7074 2002-02-28 Kevin Ryde <user42@zip.com.au>

7078 2002-02-25 Akim Demaille <akim@epita.fr>
7080 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
7081 From Akinori Musha.
7083 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
7085 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
7086 translate \r\n to \n.

7101 Fix Autoconf PR/207:
7102 AC_PREFIX_PROGRAM fails with dashed program names
7104 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7105 variable when looking for the prefix program.
7106 Now it also works for shell variables.
7108 2002-02-07 Akim Demaille <akim@epita.fr>
7110 * doc/autoconf.texi (Limitations of Builtins): More about
7111 case/esac.
7113 2002-02-06 Akim Demaille <akim@epita.fr>
7115 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
7116 case/esac, some shells don't support it.
7117 Reported by Zack Weinberg.

7120 2002-02-06 Akim Demaille <akim@epita.fr>
7122 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
7123 sure not to introduce newlines in at_groups.
7124 * lib/autotest/Makefile.am (autotest.m4f): Typo.
7126 2002-02-06 Akim Demaille <akim@epita.fr>
7128 * tests/torture.at (Configuring subdirectories): Skip if aclocal
7129 is not available.
7131 2002-02-05 Paul Eggert <eggert@twinsun.com>
7133 * doc/autoconf.texi (Specific Compiler Characteristics):
7134 Describe HP-UX cc bug workaround more accurately.
7135 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
7136 not unsigned long.
7137 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
7138 cross-compilers, too. This undoes some of the most recent change
7139 to this file.
7141 2002-02-05 Akim Demaille <akim@epita.fr>
7143 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
7144 to make sure they are up to date when `check' is run.
7146 2002-02-05 Akim Demaille <akim@epita.fr>
7148 * doc/autoconf.texi (Making testsuite Scripts): Document
7149 package.m4.
7151 2002-02-05 Akim Demaille <akim@epita.fr>
7153 * lib/freeze.mk: New.
7155 2002-02-05 Akim Demaille <akim@epita.fr>
7157 Implement `autom4te --freeze'.
7159 * bin/autom4te.in (&freeze): New.
7160 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
7161 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
7163 2002-02-05 Akim Demaille <akim@epita.fr>
7165 * bin/autom4te.in (&parse_args): Implement `frozen files are
7166 optional are the sum of the previous files on the command line'.
7167 Also, pass `--reload-state=' on them, so...
7168 (handle_m4): don't.
7169 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
7170 (M4sh): Rely on M4sugar.
7171 (Autotest, M4sh, M4sugar): Use frozen files.
7173 2002-01-31 Akim Demaille <akim@epita.fr>
7175 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
7176 * doc/autoconf.texi (Initializing configure): Adjust.
7178 2002-01-30 Akim Demaille <akim@epita.fr>
7180 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
7181 alphanumeric to `-' instead of `_'.
7183 2002-01-30 Akim Demaille <akim@epita.fr>
7185 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
7186 for plain code, the other for cross-compilation code. The latter
7187 is now run with GCC only.
7188 * doc/autoconf.texi (Compilers and Preprocessors): New.
7190 2002-01-30 Akim Demaille <akim@epita.fr>

7193 values.

7195 change AC_INIT default values.
7197 2002-01-29 Akim Demaille <akim@epita.fr>
7199 * tests/torture.at (Configuring subdirectories): Use configure.in,
7200 so that aclocal 1.4 works.
7201 Reported by Alexandre Duret-Lutz and Larry Schmitt.
7203 2002-01-28 Akim Demaille <akim@epita.fr>
7205 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
7206 needs an argument.
7208 2002-01-28 Akim Demaille <akim@epita.fr>
7210 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
7211 AUTOTEST_PATH *after* it was set.
7212 Don't put `.' in the PATH: the user should be precise and `./' if
7213 needed. In addition, given that the test suite does some `cd', if
7214 `.' is in the path, the `tested programs' sections will report
7215 programs found in the test suite's directory, while during the
7216 tests (performed in their own directory), these programs are no
7217 longer visible. In other words, the results is confusing and
7218 useless.
7219 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
7221 2002-01-24 Akim Demaille <akim@epita.fr>
7223 Version 2.52g.
7225 2002-01-24 Akim Demaille <akim@epita.fr>

7228 * doc/autoconf.texi: Finally add Akim as an author.
7230 2002-01-24 Akim Demaille <akim@epita.fr>
7232 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
7233 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
7234 Bourne. Use /bin/sh.
7235 From Andreas Buening.
7237 2002-01-24 Akim Demaille <akim@epita.fr>
7239 * config/config.guess, config/config.sub, config/texinfo.tex:

7248 * config/strip.m4: Remove, to ease sync'ing with any version of
7249 Automake.

7253 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
7254 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
7255 Reported by Geir Ove Myhr.
7257 2002-01-21 Akim Demaille <akim@epita.fr>
7259 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
7261 2002-01-21 Akim Demaille <akim@epita.fr>
7263 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
7264 message on invalid options.
7265 * bin/autom4te.in (parse_args): Don't use
7266 Autoconf::General::getopt with non valid options.
7268 2002-01-17 Jim Meyering <meyering@lucent.com>
7270 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
7271 $ac_cv_exeext so we don't use an old, invalid, cached value.
7273 2002-01-11 Akim Demaille <akim@epita.fr>
7275 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
7276 Meyering.

7278 limitation.

7282 2002-01-06 Akim Demaille <akim@epita.fr>
7284 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
7285 package.m4, since is really depends upon configure.ac, not
7286 configure.
7287 * doc/autoconf.texi (testsuite Scripts): Adjust.
7288 * tests/Makefile.am (package.m4): New.
7289 EXTRA_DIST it since its a source.
7291 2002-01-06 Akim Demaille <akim@epita.fr>
7293 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
7294 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
7295 and PACKAGE_BUGREPORT from here...
7296 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
7297 arguments.
7298 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
7299 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
7300 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
7301 * tests/tools.at (autoheader): Adjust.
7302 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
7304 2002-01-06 Akim Demaille <akim@epita.fr>

7308 2002-01-03 Akim Demaille <akim@epita.fr>
7310 * doc/autoconf.texi (Output): Improved wording regarding use of
7311 AC_OUTPUT.
7312 From Olly Betts.
7314 2001-12-18 Kevin Ryde <user42@zip.com.au>
7316 * doc/autoconf.texi (Function Portability): Add notes on sscanf
7317 sometimes needing writable input.
7319 2001-12-17 Jim Meyering <meyering@lucent.com>
7321 * doc/autoconf.texi (New Macros): Tweak wording.
7323 2001-12-14 Akim Demaille <akim@epita.fr>
7325 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
7326 trailing files, don't apply `-rf' to files which might not be
7327 created by configure (core, core.*, and *.core), but just `rm -f'.
7328 Suggested by Jonathan Kamens.
7330 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
7332 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
7334 2001-12-14 Akim Demaille <akim@epita.fr>
7336 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
7338 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
7340 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
7341 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
7342 abs_srcdir, top_srcpath to abs_top_srcdir.
7343 (_AC_OUTPUT_FILES): Adjust.
7344 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
7345 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
7346 * tests/wrappl.in, tests/wrapsh.in: Adjust.
7348 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>

7351 C/Fortran linking on HP/UX, by extracting the Fortran library
7352 search path from the LPATH line in the $F77 -v output.
7354 2001-12-12 Kevin Ryde <user42@zip.com.au>
7356 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
7357 forbidden file descriptors table.
7359 2001-11-26 Akim Demaille <akim@epita.fr>
7361 * bin/autoscan.in (%c_keywords): Build it at top level.
7362 Map to 1 in order to simplify its uses.
7364 2001-11-26 Akim Demaille <akim@epita.fr>
7366 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
7367 Remove $filepath, useless.
7368 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
7369 variables, they are really part of the tokens.
7370 Split the input line on spaces and then look for tokens.
7371 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
7372 because of `lex$U.$(OBJEXT)'.
7373 (&scan_files): Use "@list" instead of join.
7374 * doc/Makefile.am (CLEANFILES): Add *.fns.
7376 2001-11-26 Akim Demaille <akim@epita.fr>
7378 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
7379 Remove, replaced by...
7380 * tests/wrappl.in: Be common for all the Perl executables.
7381 In particular autoscan and autoheader want -I.
7382 * configure.ac: Adjust.
7383 * lib/autoscan/headers: errno.h is portable.
7385 2001-11-26 Akim Demaille <akim@epita.fr>
7387 * bin/autoscan.in (used): New.
7388 Use it.
7390 2001-11-26 Akim Demaille <akim@epita.fr>
7392 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
7393 directives.

7401 Before, having a line containing the opening of a multi line
7402 comment made the whole line be ignored.
7404 2001-11-26 Akim Demaille <akim@epita.fr>
7406 * doc/autoconf.texi (Using an Autotest Test Suite): New.
7407 (testsuite Scripts): Be one of its subsection.
7408 (Autotest Logs): New.
7410 2001-11-26 Akim Demaille <akim@epita.fr>
7412 Test groups are now run two directories deeper.
7414 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
7415 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
7416 at_top_builddir.
7417 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
7418 top_srcdir, builddir and top_builddir.
7419 Use `at_*dir' relatively to the directory containing the
7420 suite, use `*dir' when relatively to the current group dir.
7422 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
7424 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
7425 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
7426 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
7427 spelling errors.
7429 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7431 * doc/autoconf.texi (Using System Type): Add an example of `case
7432 $host' usage so people quit using `case $target' everywhere.
7434 2001-11-22 Akim Demaille <akim@epita.fr>
7436 * doc/autoconf.texi (Installation Directory Variables): Englishoes
7437 spotted by Jim Meyering.
7439 2001-11-16 Paul Eggert <eggert@twinsun.com>
7441 This patch implements a `long double' suggestion by Oliver Kiddle.
7443 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
7444 static, to catch errors if the value isn't known at compile-time
7445 and the compiler supports dynamic arrays. Change its name from
7446 `_array_' to `test_array' to avoid potential name clashes.
7447 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
7448 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
7449 better than double. Catch a bug in GCC 2.95.2 x86.
7450 * doc/autoconf.texi (C Compiler): Document the above.
7451 * NEWS: Likewise.
7453 2001-11-13 Akim Demaille <akim@epita.fr>
7455 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
7456 hand.
7457 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
7459 2001-11-13 Akim Demaille <akim@epita.fr>
7461 * lib/autotest/general.m4 (AT_INIT): After having run the test
7462 group, go back to the initial directory, not to at_suite_dir.
7464 2001-11-13 Akim Demaille <akim@epita.fr>
7466 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
7467 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
7468 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
7469 option.
7470 (AT_CHECK_CONFIGURE): Use absolute paths.
7471 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
7472 The problem is still the old one: there is no means in M4 (that I
7473 know about) to create a defining macro, because there is no means
7474 to create `$1' etc., therefore, the defining macro ``swallows''
7475 all the arguments meant to the defined macro.
7477 2001-11-13 Akim Demaille <akim@epita.fr>
7479 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
7480 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
7481 configure.ac.
7482 * tests/aclocal.m4: Remove, as it is no longer used.
7484 2001-11-13 Akim Demaille <akim@epita.fr>
7486 * lib/autotest/general.m4: Change `tests?' into `groups?' in
7487 variable names when referring to a single test group, or to
7488 `suite' when referring to the whole test suite.
7489 `at_last_test' is removed: m4 compute at_format itself.
7490 (at_stdout, at_stder1, at_stderr): New variables.
7491 (AT_CHECK): Use them.
7493 2001-11-13 Akim Demaille <akim@epita.fr>
7495 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
7496 in PATH.
7497 Create `testsuite.dir/003/run' instead of `testsuite.003'.
7498 Do it as soon as a test fails, don't wait till the end of the test
7499 suite.
7500 Don't remove $as_me.[0-9]*, since these files no longer exist.
7502 2001-11-13 Akim Demaille <akim@epita.fr>
7504 * tests/tools.at: Use absolute paths, since we are no longer run
7505 in place.
7507 2001-11-13 Akim Demaille <akim@epita.fr>
7509 Now that tests are running in their own private dir, there is no
7510 need to list the files to remove at the end of tests groups.
7512 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
7513 (AT_data_files, at_data_files): Remove.
7514 (AT_CLEANUP, AT_DATA): Simplify.
7515 (AT_INIT): Adjust.
7516 Remove the group dir if !debug && !failed.
7517 * tests/atspecific.m4: Adjust.
7519 2001-11-13 Akim Demaille <akim@epita.fr>
7521 Start a new layout for Autotest: `testsuite' creates
7522 `testsuite.dir' in which the at-check-line etc. files are to be
7523 found, and `testsuite.dir/003' where the test group 3 is run.
7525 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
7526 at_check_line_file, at_format, at_test_normalized, at_group_dir
7527 are new variables.
7528 Create the directories.
7529 Use absolute paths for at- files.
7530 (AT_CHECK): Adjust.
7532 2001-11-11 Michael Matz <matz@kde.org>
7534 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
7535 (m4_car2): New.
7536 (m4_car): Properly quote arguments.
7538 2001-11-13 Akim Demaille <akim@epita.fr>
7540 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
7541 with stricter rules on LIBOBJS.
7543 2001-11-12 Paul Eggert <eggert@twinsun.com>
7545 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
7546 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
7547 __PROTOTYPES too.
7549 2001-11-12 Akim Demaille <akim@epita.fr>
7551 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
7553 2001-11-12 Akim Demaille <akim@epita.fr>
7555 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
7556 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
7557 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7558 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
7559 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
7560 specify to what the macro should be defined (typically to 1).
7562 2001-11-12 Akim Demaille <akim@epita.fr>
7564 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
7565 From Jim Meyering.
7567 2001-11-12 Akim Demaille <akim@epita.fr>
7569 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
7570 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
7571 definition used by Automake where LEX is +/- "${missing} lex" and
7572 `missing' itself contains variables.
7574 2001-11-12 Akim Demaille <akim@epita.fr>
7576 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
7577 Now that M4sh pushes BODY, the comments were output at the end of
7578 the test suites.
7580 2001-11-08 Akim Demaille <akim@epita.fr>
7582 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
7583 that we can trace macros from aclocal.m4.
7584 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
7585 obsoleted, and redirect to the former anyway.
7586 Reported by Ralf Corsepius.
7588 2001-11-08 Akim Demaille <akim@epita.fr>
7590 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
7591 processed only if present.
7592 * tests/torture.at (Configuring subdirectories): Use autoreconf
7593 instead of successive calls to autoconf.
7594 Add a nonexistent subdirectory to exercise the patch above.
7595 Reported by Ralf Corsepius.
7597 2001-11-08 Kevin Ryde <user42@zip.com.au>
7599 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
7600 doesn't accept .S files.

7604 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
7605 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
7606 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
7607 * bin/autom4te.in (warn_forbidden): New.
7608 (handle_output): Use it.
7609 Read m4_pattern_forbid with messages.
7611 2001-11-05 Akim Demaille <akim@epita.fr>
7613 * bin/autom4te.in (--normalize): Remove.
7614 * lib/autom4te.in: Adjust.
7616 2001-11-05 Akim Demaille <akim@epita.fr>
7618 * tests/Makefile.am (testsuite): Rename this target as...
7619 ($(TESTSUITE)): this.
7620 From Nicolas Joly.
7622 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
7624 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
7625 the --prefix option, also remove it's argument.
7627 2001-11-05 Akim Demaille <akim@epita.fr>
7629 * doc/autoconf.texi (testsuite Invocation): Update.
7630 (Writing testsuite.at): Update.
7632 2001-11-03 Akim Demaille <akim@epita.fr>
7634 * doc/autoconf.texi: s/@code/@command/ where appropriate.
7636 2001-11-03 Akim Demaille <akim@epita.fr>
7638 * lib/Autom4te/General.pm: (&catfile, &canonfile)
7639 (&file_name_is_absolute): New, wrappers around routines from
7640 File::Spec.
7641 Use and export them.
7642 (&find_configure_ac): Optionally take a directory where to look at.
7643 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
7644 the arguments.
7645 Default @ARGV to `.', not find_configure_ac.
7646 (&autoreconf): Argument is a directory.
7647 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
7648 * doc/autoconf.texi (autoreconf Invocation): Update.
7650 2001-11-03 Akim Demaille <akim@epita.fr>
7652 * lib/Autom4te/General.pm (@export_vars, @export_subs)
7653 (@export_forward_subs): New.
7654 Add basename, dirname, and fileparse.
7655 (@EXPORT): Adjust.
7656 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
7657 Don't look for aclocal flags if we already know aclocal is not
7658 used.
7659 Move aclocal.m4t only if it exists.
7660 Reported by Ezra Peisach.
7662 2001-11-03 Akim Demaille <akim@epita.fr>
7664 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
7665 passed on command line, defaulting to ./configure.ac if present.
7666 (&maybe_autoreconf, File::Find): Remove, unused.
7667 (&autoreconf): If autoconf is not used, don't try to trace.
7669 2001-11-02 Akim Demaille <akim@epita.fr>
7671 * configure.ac: Bump to 2.52g.
7673 2001-11-02 Akim Demaille <akim@epita.fr>
7675 Version 2.52f.
7677 2001-11-02 Akim Demaille <akim@epita.fr>
7679 * config/config.guess, config/config.sub, doc/standards.texi:
7680 * config/lispdir.m4: Update from masters.
7681 * configure.ac: Bump to 2.52f.
7683 2001-11-02 Akim Demaille <akim@epita.fr>
7685 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
7686 Don't run aclocal when aclocal.m4 is not from aclocal.
7687 From Ezra Peisach.
7688 Don't run libtoolize and gettextize if --install is not given.
7690 2001-11-01 Paul Eggert <eggert@twinsun.com>
7692 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
7693 be invoked before _AS_LINENO_PREPARE.
7694 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
7695 than character ranges.
7697 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
7698 invoking AS_BASENAME. Set the locale variables to 'C' if
7699 possible, as POSIX requires this to get the traditional
7700 behavior.
7701 * doc/autoconf.texi (Special Shell Variables): Describe the above.
7703 2001-10-31 Paul Eggert <eggert@twinsun.com>
7705 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
7706 with {}, as that triggers a bug in Bash 2.05.
7708 (_AS_LINENO_PREPARE): Use Sed rather than
7709 Awk. Fix the sed prepass to work even if there are multiple
7710 instances of $LINENO on the same line. Do not substitute for
7711 other variables like $LINENOT. Do not check file dates; such a
7712 check is unreliable on sufficiently fast machines, and removing
7713 the check makes the code simpler and more reliable. Check for
7714 output and chmod failures.
7716 * doc/autoconf.texi (Special Shell Variables): Document
7717 the above.
7719 2001-10-31 Akim Demaille <akim@epita.fr>
7721 * tests/Makefile.am (atconfig): Remove this target, Automake
7722 handles it now.
7724 2001-10-31 Akim Demaille <akim@epita.fr>
7726 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
7727 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
7728 provided, while it is optional.
7729 * configure.ac: Adjust.
7731 2001-10-26 Paul Eggert <eggert@twinsun.com>
7733 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
7734 lib/Autom4te/Struct.pm:
7735 Require Perl 5.005_03 instead of just 5.005, as some tests fail
7736 with 5.005_02.
7738 * doc/autoconf.texi (Special Shell Variables): Document some
7739 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
7741 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
7742 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
7743 eval $LINENO is not portable in practice.
7745 2001-10-24 Akim Demaille <akim@epita.fr>
7747 * lib/Autom4te/General.pm (backname): New.
7749 2001-10-24 Akim Demaille <akim@epita.fr>
7751 * m4/: Remove, merged into...
7752 * config/: here.
7754 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
7756 * doc/autoconf.texi (Shellology): Mention the problems with bash
7757 2.05's use of ANSI quoting in its `set' builtin.
7759 2001-10-22 Paul Eggert <eggert@twinsun.com>
7761 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
7762 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
7763 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
7764 POSIX decided to standardize on the int flavor of strerror_r.
7765 Always do char* test, as there's no reason not to.
7766 Assign to a char* var, to catch strerror_r that returns int*.
7768 * doc/autoconf.texi (Particular Functions):
7769 Document the above changes. Also, document the fact that
7770 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
7772 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
7774 2001-10-20 Akim Demaille <akim@epita.fr>
7776 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
7777 the executable was missing from the log.
7779 2001-10-20 Akim Demaille <akim@epita.fr>
7781 * lib/Autom4te/General.pm (&update_file): If destination is
7782 unchanged, remove the source.
7783 (&up_to_date_p): Don't be verbose, be debug.
7784 * bin/autoreconf.in: No longer support --m4dir.
7785 (&autoreconf): Display the full path of the configure.ac we are
7786 studying.
7787 Trace it only once.
7788 Be sure to honor --force with gettextize.
7789 Always run aclocal.
7790 * doc/autoconf.texi: Adjust.
7792 2001-10-20 Akim Demaille <akim@epita.fr>
7794 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
7795 Remove, dead.
7796 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
7797 `intl' is already present, as it refuses unless --force.
7798 (&parse_args): Use -I, --include instead of the old Autoconf
7799 options.
7800 ($localdir, $autoconf_dir): Remove.
7801 (@include): New.
7802 (&maybe_autoreconf): New, to preserve $_ for File::Find.
7804 2001-10-19 Jens Petersen <petersen@redhat.com>
7806 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

7818 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
7819 comment, explain how to install automatic mode selection.
7820 From Russ Allbery.
7822 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
7824 * bin/autoreconf.in (autoreconf): Display the path to the
7825 configure.ac being studied.
7827 2001-10-18 Paul Eggert <eggert@twinsun.com>
7829 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
7830 long, to work around a bug in the HP C compiler version HP92453-01
7831 B.11.11.23709.GP.
7833 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
7834 (AS_BASENAME_EXPR): New macro.
7835 (AS_BASENAME_SED): Do not assume GNU sed semantics.
7836 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
7837 and fall back on 'sed' only if the other two fail. This makes
7838 AS_BASENAME act more like AS_DIRNAME.
7839 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
7840 contains white space.
7841 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
7842 Use AS_DIRNAME, since I think it's now DOS-friendly.
7843 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
7844 Allow "dirname //FOO" to return either / or //, as POSIX allows
7845 either behavior.
7847 2001-10-10 Akim Demaille <akim@epita.fr>
7849 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
7850 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
7851 From Eric Sharkey.

7855 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

7956 (autotest-mode): Adjust.
7957 * lib/emacs/autoconf-mode.el (autoconf-mode-map): Modernize, map

7985 empty, and if we can find a shell that does support LINENO,
7986 then set CONFIG_SHELL to that shell and then re-execute
7987 ourselves with CONFIG_SHELL.
7989 2001-10-05 Paul Eggert <eggert@twinsun.com>
7991 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
7992 doesn't exist. Remove *.tmp, as a .tmp file is created during the
7993 build of $(TESTSUITE).
7995 2001-10-05 Akim Demaille <akim@epita.fr>
7997 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

8025 combination of Awk and sed to replace $LINENO.
8027 2001-10-02 Paul Eggert <eggert@twinsun.com>
8029 * doc/autoconf.texi (Limitations of Builtins): You can't use
8030 "source"; it's not portable. Remove confusing and
8031 somewhat-incorrect example involving "." and "/".
8033 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
8034 compatibility with POSIX shells.
8036 2001-10-02 Akim Demaille <akim@epita.fr>
8038 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
8039 instead of exec'ing to preserve $0 and $@.
8041 2001-10-01 Akim Demaille <akim@epita.fr>
8043 * tests/testsuite (AT_INIT) <at_pass_list>: New.

8062 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
8063 Don't use nested parenthesization. This patch was originally
8064 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
8065 but somehow it didn't get incorporated then.
8066 * doc/autoconf.texi (Limitations of Usual Tools):
8067 Clarify remark about sed and nested parenthesization.
8069 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
8070 Report an error if the size cannot be determined even though
8071 the type exists.
8072 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8073 Check for `expr' arithmetic overflow, and for compilation failure,
8074 and invoke a new argument $4 if either is discovered.
8075 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
8076 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
8078 2001-09-28 Akim Demaille <akim@epita.fr>

8092 2001-09-27 Akim Demaille <akim@epita.fr>
8094 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that

8098 status when executing the ACTION-IF-FALSE.
8099 * tests/base.at (AC_TRY_*): Rename as...

8105 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC): Move to...
8106 * tests/c.at (Extensions, C keywords)
8107 (Broken/missing compilers, AC_PROG_CPP with warnings)
8108 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
8109 (AC_PROG_CPP requires AC_PROG_CC): here and...
8110 * tests/fortran.at (GNU Fortran 77): there.
8111 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8112 AC_TRY_RUN is about compilation, not shell commands.
8113 (Test Programs): AC_TRY_RUN works as used to be advertised.
8115 2001-09-27 Akim Demaille <akim@epita.fr>
8117 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
8118 Raja R Harinath:
8119 Be sure to detect when $LINENO always returns the same value.
8120 Look for the original script, basename($0) is certainly not
8121 enough.
8122 Pass the CLI arguments to `$as_me.lineno'.
8124 2001-09-25 Akim Demaille <akim@epita.fr>
8126 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
8127 Be sure the close and reopen the LOG fd before and after using tee

8131 2001-09-23 Akim Demaille <akim@epita.fr>
8133 * bin/autom4te.in (parse_args): There can be several invocations
8134 of --language now.
8136 2001-09-23 Akim Demaille <akim@epita.fr>
8138 * doc/autoconf.texi (Top): Wrap in @ifnottex.
8140 2001-09-23 Akim Demaille <akim@epita.fr>
8142 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
8143 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
8144 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
8145 builddir, buildpath, top_builddir, and top_buildpath.
8146 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
8147 the current directory.
8148 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir

8150 Skip nonexistent dirs.
8151 * doc/autoconf.texi (Preset Output Variables): Document these
8152 variables.
8154 * lib/autotest/general.m4: Do not reset AT_victims.
8155 Don't compute at_srcdir nor at_top_srcdir.
8157 * tests/tools.at: Hence use top_srcdir.
8159 * tests/Makefile.am, tests/autoconf, tests/autoheader,
8160 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
8161 Remove.

8172 * doc/autoconf.texi (Common Shell Constructs): Rename as...
8173 (Programming in M4sh): this.

8205 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,
8206 * m4/install-sh.m4, m4/missing.m4, m4/sanity.m4, m4/strip.m4: Updated
8207 to match current versions from CVS Automake.
8209 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>

8214 2001-09-22 Akim Demaille <akim@epita.fr>
8216 * lib/autoconf/autotest.m4: Create `package.m4'.
8217 * tests/Makefile.am (package.m4): Remove.
8219 2001-09-22 Akim Demaille <akim@epita.fr>
8221 Rely on `$LINENO' when possible instead of `__oline__'.
8223 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
8224 `$LINENO' support replacement when not supported.
8225 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
8226 them explicitly to be sure they are not output before this section
8227 (via m4_require). Cosmetic only.
8228 * lib/autoconf/c.m4, lib/autoconf/general.m4,
8229 * lib/autoconf/programs.m4: Replace all the occurrences of
8230 `__oline__' with `$LINENO'.
8231 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
8233 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>

8236 character (u: -> ue) in a code comment.
8237 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
8238 it works.
8240 2001-09-21 Akim Demaille <akim@epita.fr>
8242 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
8243 Suggested by Jim Meyering.
8245 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8247 * lib/autoconf/programs.m4: Use extensions listed in

8260 PATH_SEPARATOR.
8261 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
8262 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
8263 be used instead of ':'.
8264 * lib/autotest/general.m4: Replace occurrences of ':' in
8265 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
8267 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

8270 arguments. Fixed a typo.
8272 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8274 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
8275 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
8277 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8279 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

8286 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8288 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
8289 already have $file). Set output files to binary mode (helps avoid
8290 CR issues on DOSish systems).
8292 2001-09-19 Akim Demaille <akim@epita.fr>
8294 * lib/autotest/general.m4: Englishoes.
8295 From Tim Van Holder and Alexey Mahotkin.
8297 2001-09-18 Paul Eggert <eggert@twinsun.com>
8299 * doc/autoconf.texi (Common Shell Constructs): New node,
8300 documenting AS_DIRNAME.
8301 (Limitations of Usual Tools): Refer to it when discussing dirname.
8302 Also, update discussion of POSIX standard to reflect latest draft.
8304 * lib/autoconf/c.m4:
8305 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
8307 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8308 Do not pass a first argument with leading '-'
8309 to expr, by parenthesizing initial integers that might be negative.
8311 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
8312 now merely checks whether it is an error to pass an argument
8313 to getpgrp.
8315 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
8316 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
8317 whether it is a (compile-time) error to pass an argument to
8318 getpgrp. This simpler test supports the revised documentation,
8319 and is all that AC_FUNC_GETPGRP's users really need.
8321 2001-09-18 Akim Demaille <akim@epita.fr>
8323 * doc/autoconf.texi (Limitations of Make) <$<>: New.
8325 2001-09-18 Akim Demaille <akim@epita.fr>

8331 2001-09-18 Paul Wagland <paul@wagland.net>
8333 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
8334 correctly.
8335 Add test for AS_BASENAME.
8336 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
8337 added test. It now correctly handles /1/2/3/, returning '3' not ''.
8338 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
8339 * tests/base.at: Fixed the expected responses. The old ones were
8340 one line out...
8341 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
8342 the documentation claims it should (and how it behaved in 2.13).
8344 2001-09-18 Akim Demaille <akim@epita.fr>
8346 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
8347 the AC_CONFIG_COMMANDS invocation.
8348 This also solves the name clash problems.
8349 Don't set the package's ID.
8350 * lib/m4sugar/Makefile.am (version.m4): Revamp.
8351 No longer to be shipped.
8352 (version.in): Remove.
8353 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
8354 * lib/autoconf/status.m4: Adjust.
8355 Use `m4_PACKAGE_STRING'.
8356 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
8357 the only optional argument is the name of the test suite.
8358 Expect `package.m4' to define the package signature.
8359 * lib/autom4te.in (Autotest): Add `package.m4?'.
8360 * tests/Makefile.am (package.m4): New.
8361 * tests/suite.at: ifnames is a victim.
8363 2001-09-18 Akim Demaille <akim@epita.fr>
8365 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
8366 AC_LIBSOURCE, AC_CONFIG_FILES.
8367 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
8368 program version string doesn't match the package's.
8369 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
8370 after `(cached)'.
8372 2001-09-17 Paul Eggert <eggert@twinsun.com>
8374 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8375 Allow expression to return any value that can fit into unsigned long
8376 (not int, as before). Check for output errors.
8378 2001-09-17 Bruno Haible <haible@ilog.fr>
8380 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8381 Always include <stdio.h> and <stdlib.h>. Evaluate
8382 the expression in an extra function before these includes. Call
8383 fprintf "%d" only after ensuring the argument is of type 'int'.
8384 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
8386 2001-09-17 Paul Eggert <eggert@twinsun.com>
8388 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
8389 or CFLAGS=-O5. In that case, the linker has a relaxed view of
8390 fatal errors, and AC_CHECK_LIB causes it to include libraries even
8391 when they don't exist.
8393 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
8394 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
8395 need it.
8397 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
8398 version with the version used by fileutils 4.1, except use
8399 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
8400 we don't need it.
8402 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
8404 2001-09-13 Akim Demaille <akim@epita.fr>
8406 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
8407 _first_.
8408 Reported by Gerrit P. Haase.
8410 2001-09-13 Akim Demaille <akim@epita.fr>
8412 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

8427 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
8428 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
8429 Likewise.
8430 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
8431 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
8432 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
8433 AT_tests_all for consistency.
8434 Set at_victims.
8435 (AT_VICTIMS): Similar to AT_KEYWORDS.
8436 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
8438 2001-09-13 Akim Demaille <akim@epita.fr>
8440 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
8442 2001-09-13 Akim Demaille <akim@epita.fr>
8444 * lib/autotest/general.m4 (AT_INIT): Create and remove
8445 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
8446 test suites can cohabit.
8448 2001-09-13 Akim Demaille <akim@epita.fr>
8450 * tests/mktests.sh: Don't output banners for empty test files.
8452 2001-09-13 Akim Demaille <akim@epita.fr>
8454 Test suites can be run independently of configure.
8456 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
8457 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

8470 (AT_CHECK_PERL_SYNTAX): New.
8471 (Syntax of the Perl scripts): Check ifnames.
8472 * tests/ifnames: New.
8474 2001-09-13 Akim Demaille <akim@epita.fr>
8476 * lib/autotest/general.m4 (AT_INIT): Let --keywords also match
8477 test group titles.
8478 * tests/atspecific.m4 (AT_CHECK_AU_MACRO): AT_KEYWORDS(autoupdate).

8498 Spread a few keywords in the Autoconf test suite.
8500 2001-09-10 Akim Demaille <akim@epita.fr>
8502 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass

8516 (AC_CHECK_PROG & AC_CHECK_PROGS): Use PATH_SEPARATOR.
8518 2001-09-07 Akim Demaille <akim@epita.fr>
8520 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
8521 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
8522 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
8523 related variables into `at_package_*'.
8524 * lib/autotest/general.m4 (AT_VICTIMS): New.

8531 2001-09-07 Akim Demaille <akim@epita.fr>
8533 Move toward possibly stand-alone test suites.
8535 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
8536 in addition, it introduces useless differences in logs.
8537 (AT_INIT): Let atconfig and atlocal be both optional.
8538 Adjust PATH computation.
8539 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

8549 to avoid GCC warnings.
8550 From Uwe Seimet.
8552 2001-09-05 Akim Demaille <akim@epita.fr>
8554 * bin/autom4te.in: --language is -l, not -s.
8556 2001-09-05 Akim Demaille <akim@epita.fr>
8558 Be ready to handle filenames as stupid as `dnl.at', for if even
8559 the maintainer is dumb enough to do that...
8561 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
8562 excellence in M4 quotation: consider `__file__' is active.
8564 And BTW, when invoking m4, pass the --include in the right order:
8565 the wrong one.
8567 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
8568 4m.
8570 2001-09-05 Akim Demaille <akim@epita.fr>
8572 * lib/Autom4te/XFile.pm: New lib file.
8573 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
8574 * bin/autoheader.in: Use it.

8578 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

8586 * bin/autoscan.in: Use `getopt' and `find_files' etc.
8587 Add -I, --include support.
8588 * doc/autoconf.texi (autoscan Invocation): Adjust.
8590 2001-09-05 Akim Demaille <akim@epita.fr>
8592 CVS GNU M4 doesn't like `undefine(undefined)'.
8594 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
8595 New, extracted from main.
8596 Use IO::File wherever possible.
8597 (input.m4): Be constant, use -I instead of hard coding $tmp.
8598 Therefore be a quoted heredoc.
8599 Don't invoke `_au_disable', since ac was not loaded, but just
8600 `unm4.m4'.
8602 2001-08-31 Akim Demaille <akim@epita.fr>
8604 Version 2.52d.
8606 2001-08-31 Akim Demaille <akim@epita.fr>

8609 previous patch.

8612 2001-08-31 Akim Demaille <akim@epita.fr>
8614 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
8615 serious problems handling heredocs in heredocs.
8616 Reported by Nicolas Joly.
8618 2001-08-31 Akim Demaille <akim@epita.fr>
8620 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
8621 (Making testsuite Scripts): Update.
8623 2001-08-31 Akim Demaille <akim@epita.fr>
8625 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
8627 2001-08-31 Akim Demaille <akim@epita.fr>
8629 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
8630 (testsuite Scripts): There is no such thing as `atconfig.in'.
8631 And actually one diagram is missing: test suite runtime.
8633 2001-08-31 Akim Demaille <akim@epita.fr>
8635 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
8636 inverse order.
8638 2001-08-31 Akim Demaille <akim@epita.fr>
8640 * bin/autoupdate.in (@include): `installcheck' revealed the path
8641 to m4sugar was lacking!
8643 2001-08-31 Akim Demaille <akim@epita.fr>
8645 * man/Makefile.am (.x.1): We really have to pass
8646 autom4te_perllibdir.
8648 2001-08-31 Akim Demaille <akim@epita.fr>
8650 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
8651 debug scripts, in particular passing explicitly listed tests to
8652 run is stupid.
8654 2001-08-31 Akim Demaille <akim@epita.fr>
8656 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
8657 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
8658 Use directly autom4te, not autoconf.
8659 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
8661 2001-08-31 Akim Demaille <akim@epita.fr>
8663 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
8664 * bin/autoheader.in (%symbol): Strip arguments of macros.

8670 2001-08-31 Akim Demaille <akim@epita.fr>
8672 * bin/autom4te.in (&parse_args): Die on unknown languages.
8673 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
8674 need for autoconf.
8675 Promote --include over --macrodir and other obsolete options.
8677 2001-08-31 Akim Demaille <akim@epita.fr>
8679 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
8680 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
8681 * bin/autom4te.in ($autoconf): Pass --force.
8682 `print $out' doesn't print `$_' but `$out'.
8683 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
8684 (autoheader): Pass --force since the test suite goes too fast for
8685 the time stamps.
8686 Adjust to the new autoheader messages.
8688 2001-08-31 Akim Demaille <akim@epita.fr>
8690 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
8691 Check the completeness of the #template.

8693 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
8694 invocation.
8696 2001-08-31 Akim Demaille <akim@epita.fr>
8698 * lib/Autom4te/General.pm (&find_file, &update_file): New.
8699 * bin/autoupdate.in, bin/autoheader.in: Adjust.
8700 Drop AC_MACRODIR dead for real.
8701 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
8702 `autoheader: `config.hin' is created'.
8703 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
8705 2001-08-31 Akim Demaille <akim@epita.fr>
8707 * bin/autoheader.in: Rewrite in Perl.
8708 * tests/autoheader: Adjust.
8710 2001-08-31 Akim Demaille <akim@epita.fr>
8712 * bin/autoconf.in (--include, -I): New option.
8713 Map --localdir, --autoconf-dir onto it.
8714 Forward autom4te's options instead of interpreting them.
8715 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
8716 There is no such envvar since the inception of autom4te.cfg.
8717 * bin/autom4te.in (&parse_args): Uniquify `@include'.
8718 * bin/autoupdate.in: Adjust, and perform more control.
8719 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
8720 * tests/autoconf: Dittowise.
8722 2001-08-31 Akim Demaille <akim@epita.fr>
8724 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
8725 * bin/autom4te.in (&find_file): Support `FILE?' standing for
8726 optionally `FILE'.
8727 Use -e, not -f, since /dev/null for instance is OK.
8728 (&parse_args): Adjust.
8729 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
8731 2001-08-31 Akim Demaille <akim@epita.fr>
8733 * configure.ac: Also find tested executables in bin.
8734 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
8735 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
8736 installed peer executables, only PATH is allowed to resolve it.
8737 Pass `autoconf_dir' via options, not via invisible envvars.
8738 * lib/Autom4te/General.pm (&find_peer): Remove.
8739 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
8740 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
8741 * man/Makefile.am: Let help2man rely on PATH instead of trying to
8742 find the executables for it.
8743 * tests/Makefile.am: Major cleanup. Too lazy to document...
8744 * tests/atlocal.in: Remove all the obscure envvar manipulations.
8745 We only need PERL.
8746 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
8747 indeed related to running the test suite, while passing
8748 --autoconf-dir and others is related to running non installed
8749 Autoconf executables. So don't do that, leave it to...
8750 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
8751 * tests/autoscan: New.
8752 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
8753 refer to library files: rely on --language.
8755 2001-08-29 Akim Demaille <akim@epita.fr>
8757 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
8758 s/--set/--language/.
8760 2001-08-29 Akim Demaille <akim@epita.fr>
8762 * doc/autoconf.texi: Strip the @nodes.
8763 Suggested by Paul Eggert.

8766 2001-08-29 Akim Demaille <akim@epita.fr>
8768 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
8769 Suggested by Paul Eggert.
8771 2001-08-29 Akim Demaille <akim@epita.fr>
8773 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
8774 download in a tmp dir.
8776 2001-08-29 Akim Demaille <akim@epita.fr>
8778 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
8779 case insensitive OSes out there :(
8780 From Tim Van Holder.
8782 2001-08-29 Akim Demaille <akim@epita.fr>
8784 * lib/autom4te.in: New.
8785 * lib/Makefile.am (edit, autom4te.cfg): New.
8786 * bin/autom4te.in (BEGIN): Simplify.
8787 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.

8789 (&parse_args): Support --mode, --set, and --melt.
8790 * bin/autoconf.in: Simplify and adjust.
8791 * tests/Makefile.am (AUTOMAKE): Use --set.
8792 * tests/atlocal.in: Adjust.
8793 * BUGS: distcheck and check are weak.
8795 2001-08-29 Akim Demaille <akim@epita.fr>
8797 * lib/autotest/general.m4: Use
8798 foo=`(command) 2>/dev/null`
8799 not
8800 foo=`command` 2>/dev/null
8801 (at-devnull): Rename as...
8802 (AT-devnull): this.
8803 (--clean): Remove AT-* files too.
8804 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
8805 Reported by Nicolas Joly.
8807 2001-08-28 Akim Demaille <akim@epita.fr>
8809 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

8817 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
8819 * lib/autotest/general.m4: Reword some messages.
8820 (AT_INIT): Check for the `times' builtin before using it.
8821 Support test ranges as arguments to the testsuite.
8822 Have -e imply -d as the help text suggested.
8824 2001-08-27 Akim Demaille <akim@epita.fr>
8826 * Makefile.maint: Formatting changes.
8827 (do-po-update, po-update, cvs-update, update): New targets.

8835 <AUTOTEST_PATH>: May contain absolute dir names.
8837 2001-08-27 Akim Demaille <akim@epita.fr>
8839 * lib/autotest/general.m4 (AT_INIT): Log the command line.
8840 Support `VAR=VAL' as arguments.
8841 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
8842 may be set via the command line.
8844 2001-08-27 Akim Demaille <akim@epita.fr>
8846 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

8848 first the build dirs, then the src dirs.

8860 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
8861 `ac_top_builddir' to mimic Automake's vocabulary, which much more
8862 readable.
8863 Adjust callers.
8864 * doc/autoconf.texi (Configuration Actions): Document the vars
8865 available in commands.
8866 Emphasize the risks of collisions in init-cmds.

8870 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
8871 (Initializing configure): this new node.
8873 2001-08-27 Akim Demaille <akim@epita.fr>

8896 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
8897 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
8898 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
8899 -> ac_dir).
8900 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
8901 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

8928 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
8929 (AMTAR): Help automake define it.
8930 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
8931 needed, 1.5 can have a macro and a target with the same name.
8932 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
8933 * m4/strip.m4: New.

8948 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
8949 the name of the directory they're in, instead of the filename,
8950 since version.m4 is now in m4sugar, but m4_acversion must not be
8951 classified as an Autoconf macro.
8952 ($input_m4): Don't qualify the path to m4sugar.
8953 Rather, pass autoconf_dir to m4.
8954 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

8976 2001-08-22 Paul Eggert <eggert@twinsun.com>

9038 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
9039 * NEWS, README, README-alpha, TODO, tests/README: This package is
9040 `Autoconf', not `autoconf' (the executable).
9042 2001-08-20 Akim Demaille <akim@epita.fr>
9044 Info readers seem to need `Index' in the index node title :(
9046 * doc/autoconf.texi: Reverse the 2001-08-15 change which
9047 simplified index node names.
9049 2001-08-20 Akim Demaille <akim@epita.fr>

9091 2001-08-20 Akim Demaille <akim@epita.fr>
9093 Huh!?!?! There are still some user EOF tags used, which prevents
9094 their use in AC_CONFIG_COMMANDS for instance...
9096 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
9097 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
9098 `_CSEOF', or `_ATEOF', as appropriate.
9099 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,

9104 * tests/base.at, tests/m4sh.at, tests/m4sugar.at,
9105 * tests/semantics.at, tests/tools.at, tests/torture.at:

9158 2001-08-17 Akim Demaille <akim@epita.fr>
9160 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
9161 `$0.log' as for projects where testsuite is in src, we'd have
9162 testsuite.log created in src.
9164 2001-08-17 Akim Demaille <akim@epita.fr>
9166 * bin/autom4te.in (&parse_args): Recognize --normalize.

9176 2001-08-17 Akim Demaille <akim@epita.fr>
9178 * doc/autoconf.texi: Work around Texinfo buglets.
9179 (Transformation Rules): One example is enough, users are expected
9180 to have their brains on. And BTW, use DESTDIR.
9181 (dvar): New macro. Use it.
9183 2001-08-17 Akim Demaille <akim@epita.fr>
9185 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.
9186 * lib/autotest/general.m4 (AT_INIT): Use the relative dir when

9202 start, not at end.
9204 2001-08-15 Akim Demaille <akim@epita.fr>

9218 * doc/install.texi: Use @command.
9219 (Environment Variables): Rename as...
9220 (Defining Variables): this.
9222 2001-08-15 Akim Demaille <akim@epita.fr>
9224 * doc/autoconf.texi (Function Portability): sprintf's return
9225 value.
9226 From Kevin Ryde.
9228 2001-08-15 Akim Demaille <akim@epita.fr>
9230 * Makefile.maint (CVS): New.
9231 (local-check): Run changelog-check. last.
9232 (alpha): Don't depend upon local-check, since...
9233 (cvs-dist): depends upon it.
9235 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
9237 * tests/Makefile.am: Use a clean-local rule to remove
9238 autom4te.cache (it's a directory, not a file.
9239 * Makefile.am: Ditto (but maintainer-clean-local).
9241 2001-08-15 Akim Demaille <akim@epita.fr>
9243 * bin/autom4te.in (@m4_warning): New.
9244 (&handle_m4): Use it.
9245 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
9246 warnings are issued at each run.
9247 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
9248 is in the src tree.
9250 2001-08-15 Akim Demaille <akim@epita.fr>
9252 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
9253 don't waste time running `autoupdate --version' works.
9254 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
9256 2001-08-13 Akim Demaille <akim@epita.fr>
9258 * doc/autoconf.texi (ma): Rename this index as...

9300 ChangeLog.2, GNUmakefile, Makefile.maint, NEWS, README,
9301 README-alpha, TODO, configure.ac, lib/autoconf/Makefile.am,

9306 tests/semantics.at, tests/suite.at, tests/tools.at,
9307 tests/torture.at: Add copyright notice.
9309 * tests/mktests.sh: Update year in copyright notice.
9311 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
9313 * tests/semantics.at (AC_C_BIGENDIAN): New test.
9315 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9317 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
9318 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
9319 * doc/autoconf.texi (C Compiler Characteristics): Update
9320 documentation for AC_C_BIGENDIAN.
9322 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9324 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
9325 magic values from an object file when cross-compiling.
9326 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
9328 2001-08-10 Akim Demaille <akim@epita.fr>
9330 * bin/autom4te.in (&handle_output): Don't use `grep' with side
9331 effects.
9332 Suggested by Russ Allbery.
9334 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
9336 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
9337 current $prefix to the sub-configures.
9339 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
9341 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
9342 extension (needed on BeOS). Reported by Guido van Rossum.
9344 2001-08-09 Akim Demaille <akim@epita.fr>
9346 * bin/autom4te.in ($icache): Load it only if older than autom4te.
9348 2001-08-07 Akim Demaille <akim@epita.fr>
9350 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
9351 removed.
9352 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
9353 No need to remove the files before and after the each test, before
9354 each test and at the end of the suite is enough.
9355 Display only the children `times', not the shell's.
9356 If the test failed or was skipped, at-times is not available.
9358 2001-08-07 Akim Demaille <akim@epita.fr>
9360 Always produce testsuite.log, including when there are no
9361 failures. This helps getting information on skipped tests, and
9362 duration of the tests. Err, implement the latter btw.
9364 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
9365 Dump information on the first run of each test.
9366 (AT_CLEANUP): Create `at-times' containing the duration of the
9367 test group.
9369 2001-08-07 Akim Demaille <akim@epita.fr>
9371 The use of `dumpstat' revealed that `len' was used although it
9372 should not. m4_text_wrap was using it, but in the Autoconf world
9373 where it is legal. Hence (i) test M4sh in its own world, not
9374 Autoconf's, and (ii), ahem, fix the bug :)
9376 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
9377 does not like `' instead of [].
9378 (AT_INIT): Forbid `^_?AT_'.
9379 And don't output such tokens.
9380 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
9381 `script.as', and `autom4te.cache'.
9382 Remove `empty' and `macro' which are no longer used.
9383 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
9384 * tests/m4sugar.at: Use it.
9385 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
9387 2001-08-07 Akim Demaille <akim@epita.fr>
9389 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
9391 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
9393 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
9395 2001-08-04 Akim Demaille <akim@epita.fr>
9397 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
9398 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
9399 AC_TRY_LINK.
9400 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
9401 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
9402 (AC_F77_MAIN): Likewise.
9404 2001-08-04 Akim Demaille <akim@epita.fr>
9406 Don't rely on M4sugar outputting the patterns in files, since we
9407 might process the output _without_ running m4, hence without these
9408 files.
9410 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
9411 * bin/autom4te.in (@Request::includes): Remove, unused.
9412 (@Request::source): Rename as...
9413 (@Request::input): this.
9414 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
9415 (&handle_output): Fetch the patterns from the traces.
9416 `$forbidden' and `$allowed' are constant: use m//o.
9417 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
9418 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
9420 2001-08-04 Akim Demaille <akim@epita.fr>
9422 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
9423 autoconf', i.e., in addition to caching traces, cache the output.
9425 * bin/autom4te.in (Request::cache): Rename as...
9426 (Request::id): this.
