4 (Integer Overflow, Null Pointers, Buffer Overruns):
5 (Floating Point Portability, Exiting Portably): New sections.
6 (Writing Test Programs): Fix some langauge. Recommend exiting
7 with status 1, not merely nonzero. Clarify exit declaration.
8 (Run Time): Move C exit status stuff to new Exiting Portably section.
9 (Systemology): Mention Posix and levenez. Update v7 reference.
10 (Portable Shell): Mention the Posix shell.
12 2006-04-25 Stepan Kasal <kasal@ucw.cz>
14 * bin/autoconf.as (me): Replace by as_me.
16 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
18 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
19 since as_me isn't set yet.
21 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
23 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
24 a few minor bugs in this area.
26 * doc/autoconf.texi (Programming in M4sh): Comment out the
27 documentation of AS_BASENAME, for now.
28 (Shell Substitutions): Do not use AS_DIRNAME in an example.
29 (Limitations of Builtins) <basename>: Do not refer to
30 AS_BASENAME.
31 * bin/autoconf.as (me): Don't use AS_BASENAME.
32 (dir): Remove the unused variable.
33 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
34 AS_DETECT_REQUIRED. All uses changed.
35 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
36 All uses changed.
37 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
38 (AS_BASENAME): Use "basename --" to protect against leading "-".
39 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
40 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
41 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
42 (_AS_DIRNAME_PREPARE): Likewise.
43 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
44 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
45 (AS_DIRNAME): Use "dirname --".
47 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
49 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
50 of "run time" and "run-time" changed to "runtime", for consistency.
51 * lib/autoconf/fortran.m4: Likewise (in comment).
52 * lib/autoconf/functions.m4: Likewise.
53 * lib/autoconf/general.m4: Likewise.
54 * lib/autoconf/headers.m4: Likewise.
56 * doc/autoconf.texi (Run Time): Document the exit status situation
57 with more accuracy and detail.
59 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
61 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
62 Archive is not officially `GNU' any more. Update URL.
63 (Defining Directories): Likewise
64 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
66 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
68 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
69 newline from the `trap' code to finish `config.log'; the NetBSD
70 /bin/sh resets the exit status after an empty command, as
71 documented in doc/autoconf.texi.
72 Reported by Dalibor Topic <robilad@kaffe.org>.
74 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
76 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
77 Suggested by Bruno Haible.
79 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
81 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
82 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
83 Instead, just list the shells that we know work.
84 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
85 changed. Be more cautious about the _cv_ variable.
86 * tests/tools.at (Syntax of the shell scripts): Check the
87 _cv_ variable once, at first, to avoid an internal autoconf error
88 when sh -n does not work.
90 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
92 * lib/Autom4te/FileUtils.pm: Sync from Automake.
94 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
96 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
97 use ">&-" since we're only 99.999% sure that this is portable,
98 and since the MinGW bug is fixed in a different way.
99 * lib/autotest/general.m4 (AT_INIT): Likewise.
101 2006-04-16 Stepan Kasal <kasal@ucw.cz>
103 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
104 before opening config.log, to avoid hitting a bug on MinGW.
106 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
108 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
109 AS_MESSAGE_LOG_FD before reopening it onto the log file.
110 This works around a MinGW bug reported by Eric Paire.
111 Make sure that all writes to the log file append to it,
112 rather than possibly losing data.
113 * lib/autotest/general.m4 (AT_INIT): Likewise.
115 2006-04-14 Stepan Kasal <kasal@ucw.cz>
117 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
118 description.
120 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
122 * NEWS: Update.
124 * configure.ac (AC_INIT): Bump to 2.59d.
126 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
128 Version 2.59c.
130 2006-04-12 Stepan Kasal <kasal@ucw.cz>
131 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
133 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
134 the instantiated file do not contain the string 'datarootdir'
135 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
136 @mandir@, replace the reference '${datarootdir}' by the value.
137 * tests/torture.at (datarootdir workaround): New test.
138 * NEWS: Advertise this temporary fixup.
139 Based on a patch by Bruno Haible, reported and analyzed by
140 Paul Eggert and Noah Misch.
142 2006-04-12 Eric Blake <ebb9@byu.net>
144 * tests/autotest.at (Debugging a failed test): Fix comment.
146 2006-04-12 Stepan Kasal <kasal@ucw.cz>
148 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
149 all the changes since 2006-04-07.
151 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
153 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
154 succeeded, but `ln -s file dir' failed, take care to remove the
155 leftover target before the next test, to prevent its spurious
156 failure; also make sure `ln file dir' works before selecting it.
157 Thanks to Keith Marshall for pointing this out.
158 * THANKS: Update.
160 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
161 assignments in `at_debug_args', so that we put them correctly
162 in the `run' script.
163 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
164 Reported by Eric Blake.
166 2006-04-11 Eric Blake <ebb9@byu.net>
168 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
169 top-level tests after micro-suite has been run. Used in...
170 (Debugging a successful test, Debugging script and environment),
171 (Debugging a failed test): ...these new tests. The first of these
172 is fixed by...
173 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
174 macro, split out from...
175 (AT_INIT): ...here, so that using -d also generates a run script.
176 Document that -d inhibits top-level logging.
177 * doc/autoconf.texi (testsuite Invocation): Document that -d only
178 inhibits top-level logging; debug scripts are created.
180 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
181 check.
182 * tests/autotest.at (Empty test, Empty check): New test to check it.
184 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
185 from gcc.
187 2006-04-10 Stepan Kasal <kasal@ucw.cz>
189 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
190 the files if a problem appears. Make the empty *.at files
191 read-only, too. Proposed by Ralf Wildenhues.
193 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
195 * config/Makefile.am: Add comment to force updated Makefile.in.
197 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
198 space only patch to this file, this patch causes the Makefile.in
199 files that include freeze.mk to be updated, and thus have a
200 newer time stamp again, which in turn makes a pristine CVS
201 checkout have correct time stamps.
203 * Makefile.maint (cvs-sv): New macro, to be used..
204 (config.guess-url_prefix, config.sub-url_prefix)
205 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
206 point to CVS text checkout of Gnulib files.
207 (copyright-check): Bump current year.
208 (announcement): Do not hard-wire `./announce-gen'.
209 (cvs-update): Propagate failures of `cvs' and `move-if-change'
210 correctly.
211 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
212 `chmod +x'.
213 (wget_files): Update config.guess, config.sub, texinfo.tex by
214 `wget-update', now that their URLs work again.
216 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
218 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
219 Problem noted by Paul D. Smith.
221 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
223 * doc/autoconf.texi: Remove unused words from word list.
224 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
225 .x-sc_trailing_space: New files.
227 * doc/standards.texi: Sync from gnulib.
229 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
230 `LIBOBJDIR' as experimental.
232 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
233 with a target directory; it's internally implemented as `cp'
234 anyway, but since Autoconf advertises the possibility to use
235 a target directory when LN_S is `ln -s', we need to find out.
236 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
237 analyzed by Keith Marshall <keith.marshall@total.com>.
239 * THANKS: Update.
241 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
243 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
244 confdefs.h as-is. In general, if it has backslash-newline or the
245 like, then it doesn't work either to sort or to remove empty
246 lines.
248 2006-04-09 Stepan Kasal <kasal@ucw.cz>
250 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
252 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
254 * lib/autom4te.in (Automake-preselections): Preselect
255 _AM_SUBST_NOTMAKE.
257 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
259 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
260 apostrophe within a single-quoted string, as this is the usual
261 tradition and is easier to read than '"'"'. Don't rely on the
262 shell treating "$/" like '$/'. Use a more-consistent indenting
263 style for the trap.
265 2006-04-09 Eric Blake <ebb9@byu.net>
267 * tests/autotest.at (Backquote command substitution),
268 (Multiline backquote command substitution): Remove mistaken
269 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
270 applied...
271 (Parenthetical command substitution, Multiline parenthetical
272 command substitution): here.
274 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
276 Import macros from gnulib (often changing their name).
278 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.

292 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
293 Gnulib section.
294 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
295 suggest a #define rather than a typedef for _Bool, and mention
296 Gnulib rather than trying to substitute stdbool code.
297 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
298 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
299 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

301 (Particular Types): Mention stdint.h and inttypes.h as standard
302 headers too.
303 Add AC_TYPE_INT8_T, AC_TYPE_INT16_T, AC_TYPE_INT32_T, AC_TYPE_INT64_T,
304 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
305 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
306 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
307 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
308 (C Compiler): Move AC_C_LONG_DOUBLE to ...
309 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
310 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
311 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
312 (Coding Style). Don't mention m4_expand_once.
313 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Implement via
314 AC_TYPE_LONG_DOUBLE_WIDER. Now obsolete.
315 * lib/autoconf/functions.m4 (_AH_CHECK_FUNCS): New macro.
316 (AC_CHECK_FUNCS): Use it.
317 (AC_CHECK_FUNCS_ONCE, AC_FUNC_STRTOLD): New macros.

322 (AC_HEADER_STDBOOL): Don't assume "#error" works.
323 Catch a bug in IBM AIX xlc compiler version 6.0.0.0.
324 Catch a bug in an HP-UX C compiler.
325 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.
326 * lib/autoconf/types.m4 (AC_TYPE_INTMAX_T. AC_TYPE_UINTMAX_T):
327 (AC_TYPE_INTPTR_T, AC_TYPE_UINTPTR_T. AC_TYPE_LONG_DOUBLE):
328 (AC_TYPE_LONG_DOUBLE_WIDER, AC_C_LONG_DOUBLE, AC_TYPE_LONG_LONG_INT):
329 (AC_TYPE_UNSIGNED_LONG_LONG_INT, _AC_TYPE_INT, _AC_TYPE_UNSIGNED_INT):
330 (_AC_STRUCT_DIRENT, AC_STRUCT_DIRENT_D_INO, AC_STRUCT_DIRENT_D_TYPE):
331 New macros.
333 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
334 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
336 2006-04-08 Stepan Kasal <kasal@ucw.cz>
338 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
339 of the warning introduced by the 2001-08-28 change.
341 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
342 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
344 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
345 variables shall be overriden by the cache.
346 * tests/torture.at (AC_ARG_VAR): Test also with a first value
347 that contains braces.
349 2006-04-07 Stepan Kasal <kasal@ucw.cz>
351 Revert the patch from 2006-04-01 and only improve
352 _AS_DETECT_BETTER_SHELL:
354 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
355 skip nonexistent directories.
356 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
357 only shell candidates which exist.
358 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
359 * lib/autotest/general.m4 (AT_INIT): No need to give three
360 parameters to _AS_PATH_WALK.
362 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
363 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
365 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
366 distinguish m4sugar macros.
367 * tests/tools.at (autoupdating with aclocal and m4_include):
368 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
369 test case by Noah Misch <noah@cs.caltech.edu>.
371 2006-04-07 Stepan Kasal <kasal@ucw.cz>
373 Revert my change from 2006-03-17, in other words:
374 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
375 and DUALCASE=1.
376 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
377 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
378 it is set.
380 2006-04-07 Eric Blake <ebb9@byu.net>
382 * doc/autoconf.texi (Programming in M4sh): Document that
383 AS_MKDIR_P exits the script on failure.
384 * lib/autotest/general.m4: Remove redundant AS_ERROR.
386 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
388 * config/elisp-comp, config/install-sh, config/mdate-sh,
389 config/missing, config/mkinstalldirs: Sync from Automake.
391 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
392 from Automake.
394 * doc/make-stds.texi: Sync from gnulib.
396 2006-04-06 Eric Blake <ebb9@byu.net>
398 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
399 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
400 2006-04-01.
402 2006-04-06 Stepan Kasal <kasal@ucw.cz>,
403 Eric Blake <ebb9@byu.net>,
404 Paul Eggert <eggert@cs.ucla.edu>,
405 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
407 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
408 whether `set' quotes correctly: redirect stderr of the tested
409 `set', and use a subshell, for Ultrix; use `sed' instead of
410 `grep' for zsh `set' which may write binary output; match only
411 at the beginning of a line, to avoid false positives.
412 In order to avoid false positives by unrelated variables with
413 multiline content, put the dump algorithm in a subshell and
414 unset all variables containing newlines (except some which are
415 special to the shell). Warn about cache variables that are
416 unset.
418 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
420 * config/config.guess, config/config.sub, config/texinfo.tex:
421 Sync from upstream.
423 * tests/mktests.sh: Reword comments.
425 * tests/mktests.sh: Only skip internal macros starting with
426 `_AC_' or `__AC_'. Noted by Stepan Kasal.
427 Update exclusion lists for the test suite to this end:
428 (AC_ARG_VAR): Do test this now.
429 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
430 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
431 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
432 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
434 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
435 shell issue with double-quoted command substitutions of native
436 commands.
437 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
438 Marshall.
440 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
441 no file matches the glob, discard the warning, set `nullglob'.
442 (syntax-check): Likewise.
443 (sc_cast_of_x_alloc_return_value): Likewise.
444 (sc_cast_of_alloca_return_value, sc_error_exit_success)
445 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
446 (m4-check): Likewise.
447 (sc_system_h_headers): Do not print rule on execution.
448 (sc_tight_scope): Do not fail for non-existing `src' directory.
449 (sc_changelog): Skip the Copyright footer.
450 * lib/autoconf/lang.m4: Remove trailing space.
452 * lib/autoconf/status.m4: More replacements to
453 <tab><space> where this makes sense.
455 2006-04-06 Stepan Kasal <kasal@ucw.cz>
457 * tests/Makefile.am (maintainer-check-posix):
458 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
460 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
461 ac_config_<foo>s again, sometimes normalized, sometimes not.
462 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
463 (AC_CONFIG_COMMANDS): Do not do so here.
464 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS

473 inside m4_expand_once; it is redundant.
475 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
476 for --help from Cygnus `configure.'
478 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

534 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
535 (exclude_list): Exclude empty macros.
536 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

622 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
623 initial `rm' of the candidate files...
624 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
625 the same list in subsequent `rm' calls, and for the temporary

705 Kristian Kvilekval <kris@cs.ucsb.edu>.
707 2006-04-01 Stepan Kasal <kasal@ucw.cz>
709 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
710 switch all of them on and of when necessary. Fixes the bug when

840 `@setcontentsaftertitlepage' for HTML.

1407 the inner workings of AC_LANG_FUNC_LINK_TRY.
1408 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
1409 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
1410 by the function rather than ignoring it.
1411 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
1412 comparing its address. Intel's interprocedural optimization was
1413 outsmarting the old heuristic. Problem reported by
1414 Mikulas Patocka.
1416 2005-10-19 Stepan Kasal <kasal@ucw.cz>
1418 * lib/autoconf/general.m4 (AC_SUBST): Remove an obsolete comment.
1420 2005-10-05 Paul Eggert <eggert@cs.ucla.edu>
1422 * lib/m4sugar/m4sugar.m4 (_m4_map): New macro.
1423 (m4_map, m4_map_sep): Use it. Handle the empty list correctly.
1425 2005-10-04 Stepan Kasal <kasal@ucw.cz>
1427 * lib/autotest/general.m4 (AT_INIT): Really make the subtree writable
1428 before removing it (chmod -R u+rwx); there are three instances of this.
1430 2005-10-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1431 Stepan Kasal <kasal@ucw.cz>
1433 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
1434 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
1435 make its content writable before removing it. Remove an errorneous
1436 comment from the end, where the logs of the failed tests are copied
1437 to the main log file.
1439 2005-09-27 Stepan Kasal <kasal@ucw.cz>
1441 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,
1442 in case the computer is too quick. Double quote the configure.ac
1443 snippets.
1445 * tests/local.at (AT_CHECK_AUTOCONF): Always pass --force to prevent
1446 problems if the testsuite were running too fast.
1448 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1450 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1451 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1452 (which belong to Xt, not X itself). See Debian bug 327655.
1453 * NEWS: Mention this.
1455 2005-09-07 Stepan Kasal <kasal@ucw.cz>
1457 * lib/autoconf/c.m4 (AC_LANG_SOURCE(C)): Remove an incorrect comment.
1459 2005-09-06 Paul Eggert <eggert@cs.ucla.edu>
1461 * config/move-if-change: Don't output "$2 is unchanged";
1462 suggested by Ben Elliston. Handle weird characters correctly.
1464 2005-09-06 Stepan Kasal <kasal@ucw.cz>
1466 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
1467 calls, so that the final expansion of this macro is shorter.
1468 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
1469 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
1470 the cleanup there. Use AS_VAR_* macros, to be more general.
1471 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
1473 * lib/autoconf/general.m4: Use AS_IF where appropriate.
1475 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.
1477 2005-09-01 Stepan Kasal <kasal@ucw.cz>
1479 * doc/autoconf.texi (Configuration Headers): Add an index entry
1480 for AH_HEADER.
1482 2005-08-26 Pavel Roskin <proski@gnu.org>
1484 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use shell variable
1485 XMKMF to locate xmkmf. Make XMKMF precious. Export CC when
1486 running xmkmf.
1488 2005-08-26 Paul Eggert <eggert@cs.ucla.edu>
1490 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1491 The previous patch didn't work, so try a better one.
1493 2005-08-26 Stepan Kasal <kasal@ucw.cz>
1495 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
1496 in the example. Reported by Bruno Haible.
1497 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
1498 "if $undefined_var;" succeeds with my shell.
1500 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
1501 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
1502 but change the m4_divert_text to m4_divert_once.
1504 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
1506 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
1507 Work around bug in Solaris /usr/xpg4/bin/awk.
1508 The bug is present in at least Solaris 8 through 10.
1510 2005-08-24 Stepan Kasal <kasal@ucw.cz>
1512 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
1513 some evil values and relying on the fact that $* concatenates the
1514 parameters by the first character from IFS.
1516 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
1517 Stepan Kasal <kasal@ucw.cz>
1519 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
1520 first header appears, define AH_HEADER.
1521 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
1522 Update limitations about when to call AC_CONFIG_HEADERS.
1523 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
1524 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
1525 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
1526 ``Configuration Actions''; fix their index entries.
1528 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
1529 options correctly. Process N-M as M-N if M is smaller than N.
1530 Process ranges correctly so that N-N will run only N.
1531 Sort and uniquify the tests that will be run. If there is more
1532 than one test, reinsert the banners for the tests.
1533 * tests/autotest.at (Keywords): Unmark XFAIL.
1535 2005-08-23 Stepan Kasal <kasal@ucw.cz>
1537 * lib/autoconf/general.m4 (_AC_DEFINE_Q): Strip the parameter list
1538 before passing the macro name to AH_TEMPLATE.
1540 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
1541 now opens log after option processing; in particular, --version
1542 and --help do not touch config.log.
1544 * Makefile.maint: Revert the change from 2005-08-12.
1546 2005-08-22 Stepan Kasal <kasal@ucw.cz>
1548 * lib/autoconf/general.m4 (AC_ARG_ENABLE, AC_ARG_WITH): Factor out
1549 common code to...
1550 (_AC_ENABLE_IF, _AC_ENABLE_IF_ACTION): ... these new macros.
1552 2005-08-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1554 * doc/autoconf.texi (Using Autotest, testsuite Scripts)
1555 (Autotest Logs, Writing testsuite.at, testsuite Invocation):
1556 Language cleanup.
1558 * doc/autoconf.texi (Defining Symbols, Changed Results):
1559 Prepend to LIBS, not append, in examples.
1561 2005-08-16 Stepan Kasal <kasal@ucw.cz>
1563 When building in place, set srcdir="."; suggested by Tim Van Holder.
1565 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
1566 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
1567 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
1568 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
1569 does not mean "no --srcdir option".
1571 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1573 * tests/autoscan.at (autoscan): New file.
1574 * tests/suite.at: Use it.
1575 * tests/Makefile.am (TESTSUITE_HAND_AT): Add it.
1576 Reported against Libtool by Gideon Go <gideon.go@gmail.com>.
1578 * tests/autotest.at (Keywords): Test keywords combinations.
1580 2005-08-12 Stepan Kasal <kasal@ucw.cz>
1582 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
1583 add "2>&1"; gzip 1.2.4 prints help on stderr.
1585 2005-07-27 Stepan Kasal <kasal@ucw.cz>
1587 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
1588 was pushdef'ed twice while popped only once. Push it only once.
1589 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
1591 2005-07-26 Stepan Kasal <kasal@ucw.cz>
1593 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
1594 prefixed by mere "===", not "configure: === ".
1596 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
1598 * Makefile.maint: Update from Bison.
1600 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
1601 "<tab>" in comment, so that the point is understandable.
1603 2005-07-25 Stepan Kasal <kasal@ucw.cz>
1605 Rewrite substantial part of lib/autoconf/status.m4.
1606 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
1607 and CONFIG_COMMANDS are not processed in four separate loops.
1608 Instead, there is one main loop. This alows that the common code
1609 is expanded only once, thus config.status (and configure) is smaller.
1611 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
1612 the AC_LIST_FILES and cousins macros are no longer used.
1614 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
1615 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
1616 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
1617 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
1618 contain the initialization, nor the for loop, nor the associated
1619 commands; all these go to ...
1620 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
1621 _AC_OUTPUT_CONFIG_STATUS.
1622 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
1623 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
1624 (_AC_OUTPUT_FILE): The creation of the sed script ...
1625 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
1626 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
1627 _AC_OUTPUT_MAIN_LOOP.
1628 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
1629 _AC_CONFIG_COMMANDS): Use ...
1630 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
1631 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
1632 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
1633 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
1634 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
1635 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
1636 ... new macros.
1637 (_AC_CONFIG_UNIQUE): Update.
1638 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
1639 Replaced by this ...
1640 (_AC_LIST_TAGS): ... new common macro.
1641 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
1642 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
1643 (_AC_LIST_TAG_COMMANDS): ... new common macro.
1644 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
1645 this didn't belong to the `config commands' section.
1646 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
1647 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
1648 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
1649 to the `config commands' section either.
1650 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
1651 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
1653 ... and many changes to the comments nearby.
1655 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
1656 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
1657 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1658 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
1659 (#define header templates): The comment at the top of the generated
1660 header now includes the name(s) of the source file(s).
1662 Several unrelated small changes:
1664 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
1665 parameter to AC_DIAGNOSE.
1666 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
1667 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
1668 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
1669 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
1670 with AU::AC_OUTPUT.
1671 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
1672 in AC_OUTPUT doesn't double-quote it either.
1673 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
1674 parameters.
1676 2005-07-10 Stepan Kasal <kasal@ucw.cz>
1678 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
1679 versions of Portland Group compiler produce single- and double-quoted
1680 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
1681 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
1683 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
1685 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
1686 This is a corrected version of yesterday's patch.
1688 2005-07-07 Stepan Kasal <kasal@ucw.cz>
1690 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
1691 path, too; insert a "===" to emphasize the line.
1693 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
1694 ac_cv_build_alias to ac_build_alias.
1695 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
1697 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
1698 change eliminates it. Problem reported by Alexandre Duret-Lutz.
1699 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
1700 (AC_ARG_VAR): ... here.
1701 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
1702 target_alias.
1704 Keep a list of all precious variables and process them with one simple
1705 for loop, instead of expanding all commands, or, OTOH, complicated
1706 processing of output of "set".
1707 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
1708 variable names in new macro...
1709 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
1710 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
1711 a loop to assign all ac_env_* and ac_cv_env_* variables.
1712 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
1713 to INIT_PREPARE.
1714 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
1715 its value to shell variable ac_precious_vars and call
1716 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
1717 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
1718 _AC_ARG_VAR_VALIDATE.
1720 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
1721 and the AC_SUBSTs ...
1722 (AC_INIT): ... here.
1724 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
1725 the ac_subst_files section in config.log.
1727 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.
1729 2005-07-06 Paul Eggert <eggert@cs.ucla.edu>
1731 * NEWS: New macro AC_C_TYPEOF.

1736 Fix problems reported by Nicolas Joly.
1737 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
1738 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
1739 They are generated by the Tru64 v5.1B shell.
1741 2005-07-05 Stepan Kasal <kasal@ucw.cz>
1743 Fix my changes from 2005-07-01; reported by Noah Misch.
1744 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
1745 description, the macro now accepts only a single tag.
1746 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
1748 Fix cases when the varsions of Autoconf and Autotest don't match.
1749 Reported by Noah Misch.
1750 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
1751 at_top_builddir, for compatibility with older autotest.
1752 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
1753 is not set, use at_top_builddir, for compatibility with older
1754 versions of autoconf.
1756 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
1758 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
1759 Problem reported by Patrick Welche.
1761 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
1763 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
1764 sed substitution command, so that we allow | in program prefixes
1765 and program suffixes. (& is a problem anyway; we're not fixing
1766 that here.)
1767 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
1768 configure_input, top_builddir, srcdir, etc.
1769 * lib/autotest/general.m4 (AT_INIT): Likewise, for
1770 PATH_SEPARATOR in AUTOTEST_PATH.
1772 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
1774 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
1775 for loop over config.site files using `set', to allow
1776 directory names containing IFS characters.
1778 2005-07-01 Paul Eggert <eggert@cs.ucla.edu>
1780 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
1781 directories with weird names. Apparently some people like living
1782 on the edge. However, improve the test that "pwd" actually does
1783 report a name for the working directory.
1784 * NEWS: Remove the claim that we test for funny chars in dir names.
1786 2005-07-01 Stepan Kasal <kasal@ucw.cz>
1788 * lib/autoconf/general.m4 (AC_FOREACH): Make obsolete; it's
1789 replaced ...

1798 about #include <config.h>.
1799 (Generic Functions): Mention the Gnulib project.
1800 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
1802 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
1803 document to output the default config_* lists to config.status.
1804 Don't recognize option --file, if the functionality is not there.
1805 Likewise for --header; moreover, recognize --he and --h as shortcuts
1806 for --help in that case.
1808 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
1809 matches the order of execution. No code changed.
1811 2005-06-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1813 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Fix also for
1814 single-quoted -cmdline argument in Portland Group compiler.
1815 Reported against LAM by Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
1817 2005-06-30 Alexandre Duret-Lutz <adl@gnu.org>

1821 2005-06-29 Stepan Kasal <kasal@ucw.cz>
1823 * doc/autoconf.texi (File Descriptors): ksh doesn't pass open file
1824 descriptors to child processes; reported by Norman Gray.
1826 2005-06-29 Stepan Kasal <kasal@ucw.cz>
1828 * lib/autoconf/general.m4 (AC_ARG_VAR): Move next to _AC_ARG_PRECIOUS.
1830 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
1831 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
1832 (AC_SUBST): Call it.
1833 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
1834 the directory specific variables; but don't call it for configure_input.
1836 2005-06-28 Derek Price <derek@ximbiot.com>
1838 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
1839 addition.
1841 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
1843 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
1844 directory have inherent problems with special characters like spaces,
1845 due to limitations in Make syntax. Problem reported by Alexandre
1846 Duret-Lutz.
1847 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.
1848 Also, fix Tru64 porting problem with shell patterns,
1849 reported by Ralf Wildenhues.
1851 2005-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1853 * doc/autoconf.texi (Subdirectories): Fix markup typos.
1855 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

1859 Fix some more shell quoting problems. Prompted by a bug report
1860 from Justace Clutter.
1861 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
1862 variable into diagnostic. Make the diagnostic an error, not a warning,
1863 because we really don't support spaces and suchlike in dir names.
1864 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
1865 Don't worry about backslashes in srcdir; it can't happen now.

1876 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
1878 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
1879 that '\|' is not allowed in BREs; recommend using newline separated

1894 (Special Shell Variables): Fix sed code this in the example.
1895 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
1896 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
1898 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
1899 expand to the empty list. Don't use two pairs of m4_changequote,
1900 it's not necessary.
1902 2005-06-20 Derek Price <derek@ximbiot.com>
1904 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.

1908 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
1909 * doc/autoconf.texi:
1910 Don't mention Solaris versions so much, if a
1911 problem is common to all extant versions of Solaris. Say "SunOS
1912 4" instead of "SunOS" for SunOS 4.
1913 (awk): Mention more of the limitations of traditional Awk.
1914 (cat): Don't talk about cat -v.

1927 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
1928 Use shell builtins rather than 'expr', to work around expr bug.
1930 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
1932 * doc/autoconf.texi: "filesystem" -> "file system".
1933 "behaviour" -> "behavior".

1935 * lib/autoconf/general.m4: Omit blank after ":" sed command,
1936 as per POSIX.
1937 * lib/m4sugar/m4sh.m4: Likewise.
1938 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Work around problem
1939 with Solaris sed. Fix by Ralf Menzel and Stepan Kasal.
1941 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
1942 (.x.1): Ignore the time stamp in the .TH line when deciding whether

1944 man pages every month.
1946 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
1947 quotes and backslashes. Patch from Derek Price.

1956 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
1957 -u, since it outputs chatter if the input files are the same.
1958 Problem reported by Ralf Menzel.
1960 2005-06-08 Derek Price <derek@ximbiot.com>
1962 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
1963 renaming them since they are about to be redefined anyhow.
1965 2005-06-08 Derek Price <derek@ximbiot.com>
1967 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
1968 redefined M4 macros to this node. Document m4_include & m4_sinclude.
1969 Move m4_undefine to alphabetical order.
1971 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
1973 * README: Recommend GNU M4 1.4.3 or later.
1974 * doc/autoconf.texi (Introduction): Likewise.
1975 Reword to avoid some formatting glitches.
1976 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
1977 Clarify explanation of HP compiler bug.
1978 Redo example output tp match current CVS snapshot.
1979 Use @example.org in email addresses when the examples
1980 might get inadvertently cut-and-pasted into user code.
1981 Remove example of autom4te usage that doesn't seem to work now.
1982 Use modern AC_INIT (except when the example is meant to be
1983 shown with Autoconf 2.13).
1984 Update ksh info for Solaris 9 and later.
1985 KB -> kB.
1986 Modernize description of Automake versions a bit.
1987 Don't claim a future version of Autoconf is near.

1993 follows its own advice about quoting better.
1994 Reword to avoid some formatting glitches.
1995 * doc/installt.exi: Reword to avoid some formatting glitches.
1997 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
1998 Tru64 ksh pattern matching bug. Reported against Libtool by
1999 Albert Chin <libtool@mlists.thewrittenword.com> and
2000 Nicolas Joly <njoly@pasteur.fr>.
2002 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2004 m4_cdr of one-member list was [[]] (one-member list containing an
2005 empty string) instead of [] (an empty list. Callers were skewed to
2006 match this misbehaviour. As a consequence of this:
2007 - m4_foreach([x], [], [foo]) expanded to `foo', while
2008 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2009 This bug has been fixed:
2011 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2012 expand to an empty string; print error msg if called without
2013 an argument list.
2014 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2015 misbehaviour; handle [] and [[]] correctly.
2017 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2019 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.

2021 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2023 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2025 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2026 swallow records with more than 99 fields.
2027 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2028 parse the long line.
2030 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2032 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2033 swallow literals longer than 399. Reported by Ralf Wildenhues.
2034 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,

2037 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2039 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2040 to gfortran, and make these the first two compiler names
2041 checked (following the general autoconf preference for gcc).
2043 2005-06-03 Stepan Kasal <kasal@ucw.cz>
2045 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2046 (DISTCLEANFILES): Remove $(check_SCRIPTS).
2047 (testsuite): Make sure autotest.m4f is up-to-date before using it.

2051 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2052 expression of unbounded size when processing the --list
2053 option. This runs afoul of a limit of 399 bytes per regular
2054 expression on AIX. Problem reported by Ralf Wildenhues.
2056 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>

2059 * doc/autoconf.texi (Particular Headers): Reword example
2060 for multiline stdbool replacement.
2061 (Setting Output Variables): Reword text a bit. Don't
2062 give all the details about |#_!!_#|.
2063 Reword description of line replacement.
2065 2005-05-31 Dan Manthey <dan_manthey@partech.com>
2067 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2068 now contain newlines, and substituted files must be referenced on
2069 a line alone; the sed scripts to substitute them are now very
2070 different.
2071 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
2072 commands can be put in a sed script portably.
2073 * doc/autoconf.texi (Setting Output Variables): Document above
2074 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
2075 use of multiline substitution.

2085 * tests/local.at: Don't attempt to check for negated character
2086 classes in shell scripts. The test was too brittle.
2088 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2090 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
2091 * doc/autoconf.texi (Limitations of Builtins): Document this
2092 limitation.
2094 2005-05-24 Stepan Kasal <kasal@ucw.cz>

2104 messages when ac_unique_file is not found.
2105 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
2106 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
2107 commands, for consistency with AC_MSG_ERROR and such.
2109 * bin/autoconf.as: Make more use of "shift 2" in option processing.
2111 * bin/Makefile.am: Merge the two rules for creating scripts.

2119 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2121 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
2122 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2123 (ac_top_builddir): ... this ...
2124 (ac_top_build_prefix): ... to this; the old name is also kept, for
2125 backward compatibility.
2126 (ac_top_builddir_sub): New variable, without the trailing slash,
2127 always nonempty.
2128 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
2129 * doc/autoconf.texi (Configuration Actions): Rename
2130 ac_top_builddir to ac_top_build_prefix.
2131 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
2132 at_top_builddir to at_top_build_prefix.

2140 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2142 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2143 argument to m4_foreach. I guess it was necessary in the past,
2144 but I think it's a no-op now.
2146 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2148 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2149 ``cat <<_ACEOF'' commands to one.
2150 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2151 * lib/autoconf/status.m4: On various places, use expr instead of
2152 ``echo|sed.''
2153 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2154 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2155 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2156 a range.
2157 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2158 the wrong patterns between ``case'' and ``esac.'' The previous
2159 code had false positives.
2161 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
2163 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
2164 as on 2005-05-02.
2165 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:

2228 quoting rules. Problems noted by Stepan Kasal.
2229 Also, throughout this document, be more careful about white space.
2230 "blank", "white space", and "space" all have different meanings
2231 and we should be careful to say what we mean.
2233 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
2235 Fix C++ related problems reported by Werner Lemberg.
2236 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

2283 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2284 comment and reduce m4_default([foo], []) to [foo].
2285 (m4_strip): Update the explanation.
2287 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2289 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):

2292 * lib/autoconf/functions.m4
2293 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):

2295 for you.
2297 2005-04-19 Stepan Kasal <kasal@ucw.cz>

2316 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2318 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
2319 as well as configure.in. Problem reported by Gregorio Guidi.
2321 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
2323 * doc/autoconf.texi (Particular Functions): Use gnulib's current
2324 pattern for alloca snippet.

2334 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
2336 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
2337 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
2339 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2341 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
2342 Merge `-z option' as well for the benefit of Solaris link flags. Pass
2343 whole-archive (-zallextract, -zdefaultextract) options in the hope of
2344 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
2345 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
2347 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
2349 * NEWS: The configure command now warns you if you attempt to use
2350 a directory whose name contains a special character like space,
2351 newline, or "\".
2352 * doc/autoconf.texi (Installation Directory Variables): Allow
2353 "," in file names. Do not use \@; it's not a portable regexp.
2354 * bin/Makefile.am (edit): Likewise.
2355 * lib/Makefile.am (edit): Likewise.
2356 * tests/Makefile.am (edit): Likewise.
2357 * tests/semantics.at: Likewise.

2361 * doc/autoconf.texi (File System Conventions): Warn about
2362 unportable file names.
2363 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
2364 (AC_INIT): Use it.
2365 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
2366 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
2367 ac_pwd, and quote srcdir.
2368 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
2370 * doc/autoconf.texi: Fix some systematic formatting problems.
2371 ".)" needs a following @: if not at the end of a sentence, and
2372 similarly for "!)". "etc." should be preceded by a comma.
2373 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2375 2005-03-22 Bruno Haible <bruno@clisp.org>
2377 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
2378 argument is often called 'build-aux'.
2380 2005-03-07 Stepan Kasal <kasal@ucw.cz>
2382 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
2383 macro AC_TRY_LINK is obsolete.
2384 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
2385 `AC_CONFIG_FILES'.
2387 2005-02-24 Stepan Kasal <kasal@ucw.cz>
2389 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
2390 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
2391 from a Common Lisp's `cl'.
2392 (AC_PROG_CXX): Behave according to the documentation: don't
2393 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
2394 make the variable CCC precious; use `cl.exe', not `cl'.
2396 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2397 Alexandre Duret-Lutz <adl@gnu.org>
2399 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
2400 /dev/null, as "configure" shouldn't read stdin, and this insulates
2401 us from problems (e.g., when testing for "cl"). Also, do this
2402 redirection before invoking "hostname" or "uname", and keep the
2403 original input stream available via...
2404 (AS_ORIGINAL_STDIN_FD): ... this new macro.
2405 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
2406 bother with "</dev/null" since it's now done at the top of
2407 'configure'.
2408 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
2409 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.

2415 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2417 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
2418 newline if neither \c nor -n work, as that would output two
2419 newlines. Prefer -n to \c. Reported by Stepan Kasal.
2421 2005-02-12 Stepan Kasal <kasal@ucw.cz>
2423 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
2424 This causes that any required macros inside will get before the if.
2425 * doc/autoconf.texi (autom4te.cache): A typo.
2427 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
2429 Undo previous change, except keep the change to
2430 lib/autoconf/programs.m4 that replaced grep with shell
2431 pattern-matching. This is because net-snmp configure reads stdin.
2432 Reported by Noah Misch.
2434 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
2436 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
2437 from /dev/null, as "configure" shouldn't read stdin, and this
2438 insulates us from problems (e.g., when testing for "cl").
2439 Suggested by Alexandre Duret-Lutz. Also, do this redirection
2440 before invoking "hostname" or "uname".
2441 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2442 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
2443 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
2444 "</dev/null" since it's now done at the top of 'configure'.
2445 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2446 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2447 Also, replace grep with shell pattern-matching, to save a process.
2449 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
2451 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2452 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
2453 avoid thinking that Allegro Common Lisp's "cl" command is a C++
2454 compiler.
2456 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
2458 * doc/autoconf.texi (Limitations of Usual Tools): Document that
2459 grep -q isn't portable. Improve grep -s explanation.
2460 Problem reported by Dan Manthey.
2462 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
2464 * doc/autoconf.texi (Special Shell Variables): Clarify
2465 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
2467 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
2469 * doc/autoconf.texi: Use @acronym for DJGPP.
2470 Fix some @code's that should have been @env's, and vice versa.
2471 Sort environment variable names.
2472 Mention that shells no longer inherit IFS.
2473 Don't recommend PATH_SEPARATOR=';' so strongly.
2474 Mention that $RANDOM might expand to the empty string.
2475 "symlink" and "soft link" -> "symbolic link".
2476 Improve mktemp description (reported by Bruno Haible).
2478 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
2480 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
2481 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
2482 Likewise.
2483 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
2484 Likewise.
2486 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
2488 * NEWS: Mention AT_COPYRIGHT.
2490 * tests/local.at (AT_CMP): Use diff directly on input files rather
2491 than copying them.
2493 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
2494 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
2496 2005-02-04 Noah Misch <noah@cs.caltech.edu>
2497 and Paul Eggert <eggert@cs.ucla.edu>
2499 * tests/autotest.at (Empty test suite): New test.

2506 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
2507 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
2508 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
2509 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
2510 (Standard regular expressions): New test.
2511 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
2512 excess test name quoting.
2513 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
2514 CPPFLAGS to `configure' instead of setting it in `configure'.
2516 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
2517 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
2518 on some platforms.
2520 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
2521 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.

2549 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
2551 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
2552 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
2554 Try not to generated lines of unlimited length, as POSIX places a
2555 2047-byte limit on line length of portable text files.
2556 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
2557 Use newline as a separator, not space.
2558 * lib/autotest/general.m4 (AT_TESTED, AT_KEYWORDS): Likewise.
2559 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
2560 space.
2562 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2564 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
2565 as_func_*. Add test to check whether positional parameters
2566 are restored after function return.
2568 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
2570 * doc/autoconf.texi (Special Shell Variables): Mention _,
2571 BIN_SH, DUALCASE. Say that variables other than "status" are safe
2572 if they contain a lower-case letter. The DUALCASE problem was
2573 reported by Ralf Wildenhues.
2575 * bin/autoconf.as: Don't exit with status 0 after write failure
2576 with --help or --version.
2577 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

2583 Unicos 9 sed limitations.
2584 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Try cf77 before fort77
2585 to get the option-enhanced interface on older Crays. Try ftn for
2586 Fortran 95 (newer Crays).
2588 2005-02-01 Paul Eggert <eggert@cs.ucla.edu>
2590 * man/Makefile.am (.x.1): Go back to the simple solution, but take
2591 care to echo the commands, so the user knows what's going on.
2592 Modified from a suggestion by Stepan Kasal.
2594 * doc/autoconf.texi (autoreconf Invocation): Mention autopoint,

2601 * doc/install.texi (Defining Variables): Likewise.
2602 Based on a proposed patch by Ralf Wildenhues.
2604 * man/Makefile.am (.x.1): Make sure the required generated files
2605 are up to date. Problem and original solution proposed by Stepan Kasal.
2606 $(dist_man_MANS:.1=-bin-prereq), $(dist_man_MANS:.1=-tests-prereq),
2607 implicit-man-prerequisites): New rules, used by the above.

2613 2005-01-29 Stepan Kasal <kasal@ucw.cz>
2615 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
2616 Update the long comment explaining it.
2618 m4_require no longer writes an ``is required by'' line to the
2619 execution stack. It contains only one bit of non-redundant
2620 information: that the macro was required, not called. And even
2621 this bit is useless in most situations: have you ever met a macro
2622 which both calls and requires the same macro?
2624 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
2625 (_m4_defun_pro_outer): ... only via this macro, for the outermost
2626 macro.
2627 (_m4_defun_epi, _m4_defun_epi_outer): Complementarily.
2628 (m4_expansion_stack_pop): Remove the misplaced comment.
2629 (m4_require): Don't put the ``is required by'' line to the
2630 execution stack; slightly improve the out-of-a-defun error message.
2631 (_m4_divert_grow): New macro, counter for the temporary diversions.
2632 (_m4_require_call): Use it.
2633 * tests/m4sugar.at (m4_require): Expect output without the
2634 ``is required by'' messages.
2636 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2638 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
2639 rather than x for expr.
2641 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
2642 this is safe.
2643 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
2644 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

2655 * lib/Autom4te/FileUtils.pm, lib/Autom4te/XFile.pm: Update
2656 from masters, so that FileUtils.pm's update_file provide --force
2657 support.
2658 * bin/autoheader.in: Pass $force to update_file so that
2659 config.h.in is always recreated when --force.
2661 2005-01-24 Stepan Kasal <kasal@ucw.cz>
2663 * doc/autoconf.texi (Introduction): Update Peter Simons' address.
2665 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2667 * doc/autoconf.texi (Limitations of Builtins): Clarify that
2668 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
2670 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
2672 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
2673 Warn about newline stripping in `` and $(). Update Solaris
2674 version to 9.
2675 (Limitations of Builtins): Use expr "X...", not expr "x...", as
2676 X insulates us from future changes to Posix.
2677 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
2678 stripping.
2680 2005-01-19 Stepan Kasal <kasal@ucw.cz>

2698 ulongval to be static, to avoid unwanted GCC warning. Problem
2699 reported by Michael Jennings via Daniel Reed; see
2700 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
2702 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
2704 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,
2705 docdir, htmldir, dvidir, pdfdir, psdir, and localdir. Update
2706 datadir, infodir, and mandir. Adjust argument parsing code.
2707 (_AC_INIT_HELP): Update help text.

2709 new variables.
2711 2005-01-04 Noah Misch <noah@cs.caltech.edu>
2713 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
2714 not seem to work, assume it does set $(MAKE).
2715 * doc/autoconf.texi (AC_PROG_MAKE_SET): Update.
2717 2005-01-03 Stepan Kasal <kasal@ucw.cz>
2719 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Add a comment about nesting.

2725 * lib/m4sugar/m4sugar.m4 (_m4_divert): A typo in description.
2726 (_m4_divert_n_stack): New macro; the expansion is
2727 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
2728 otherwise.
2729 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
2730 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
2731 stored in _m4_divert_diversion or _m4_divert_dump.
2732 (m4_divert_pop): When the parameter is given, compare the symbolic
2733 name with the last diversion pushed on the stack. Previously, the
2734 current diversion was compared with the numeric value of the
2735 diversion given as the parameter.
2736 (m4_require): If the macro hasn't been expanded yet, call ...
2737 (_m4_require_call): this new macro.
2739 2005-01-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

3044 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use

3225 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3227 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
3228 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
3229 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
3230 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
3232 More fixes to support spaces in the name of the build directory.
3233 This isn't a complete fix but it's an improvement.
3235 * bin/autoconf.as (autom4te_options): New var.
3236 Use it instead of appending to AUTOM4TE, so that we can allow
3237 spaces in the build directory's absolute name.
3238 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3239 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
3240 AT_CHECK_NOESCAPE): Likewise.
3241 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
3242 main program): Likewise.
3244 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>

3250 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
3252 * doc/autoconf.texi (Function Portability): Document isinf and
3253 and isnan. From a suggestion by Kevin Ryde.
3255 * lib/Autom4te/General.pm (END): Return correct exit status even
3256 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
3258 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3260 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3261 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3262 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3264 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3266 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3267 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3268 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3269 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3270 * lib/autom4te.in (Automake-preselections): Preselect
3271 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3273 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3275 * lib/autom4te.in (Automake-preselections): Preselect
3276 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3277 trace them.
3279 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
3281 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
3282 Tru64.
3283 * doc/autoconf.texi (Shellology): Mention BIN_SH.
3284 Document problem with "`""`" in pdksh POSIX mode.
3286 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
3288 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3289 with pdksh, too. Problem reported by Patrick Welche via
3290 Gary V. Vaughan.
3291 * doc/autoconf.texi (Shellology): Note that set -o posix is
3292 useful for pkdsh, too.
3294 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3296 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3297 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3298 Don't fail if ENV or BASH_ENV is readonly.
3299 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
3300 etc. are read only. Problem reported by Ludovic Courtes.
3302 2004-06-23 Noah Misch <noah@cs.caltech.edu>
3304 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
3305 zsh, disable GLOB_SUBST to avoid backslash handling problems.
3306 (trivial change)
3308 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
3310 * doc/autoconf.texi (File System Conventions): Warn about
3311 names like "aux". Problem reported by Eric Blake.
3313 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3314 by zero instead of array size, so that we can use any arithmetic
3315 constant expression (instead of requiring an integer constant
3316 expression). This allows us to test expressions like DBL_MAX <
3317 LDBL_MAX, which didn't conform to the C standard using the old
3318 method.
3319 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3320 now that we can do floating-point tests at compile time.
3322 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
3324 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
3325 and LDBL_EPSILON, as the resulting expression isn't an
3326 integer constant expression and violates the C standard.
3327 Problem reported by Nelson H. F. Beebe. Also, check
3328 for "L" suffix, and check that long double doesn't have
3329 worse range or precision than double, that mixed-mode
3330 arithmetic doesn't generate a diagnostic, that double
3331 constants fit in long double.
3333 2004-06-03 Kevin Ryde <user42@zip.com.au>
3335 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
3336 malloc(0) and realloc(NULL,size).
3338 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
3339 Bob Proulx.
3341 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
3343 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
3344 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
3345 by Jim Meyering.
3347 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3349 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
3350 can be rewritten using if-then-else. Suggested by Bruno Haible.
3352 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3354 * doc/autoconf.texi (testsuite Scripts): Fix typo.
3355 Problem reported by Stepan Kasal.
3357 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3359 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
3360 change). Patch reported by Ralf Wildenhues in
3361 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
3363 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
3364 function F exists if the compiler and linker let you compile an
3365 expression like (F != 0). Recent versions of GCC optimize away
3366 the reference to F in that case, since every function address must
3367 be nonzero, so the link succeeds even if F does not exist.
3368 Problem reported by Manu in
3369 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
3371 * doc/autoconf.texi (Systemology): Standardize on the spelling of
3372 "Unix". Many uses changed.
3373 (Limitations of Builtins): Explain better why the ! command isn't
3374 portable.
3376 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
3378 * lib/autom4te.in (Automake-preselections): Preselect
3379 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
3381 2004-05-19 Kevin Ryde <user42@zip.com.au>
3383 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
3384 referencing AC_FUNC_STRERROR_R.
3386 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
3387 note pessimistic assumption when cross compiling.
3389 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
3391 * doc/autoconf.texi (Limitations of Make): Note that BSD make
3392 (until 2004) invoked subcommands with sh -e, contra POSIX.
3393 Reported by Kevin Ryde.
3395 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
3397 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
3398 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
3399 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
3400 `test -f " /usr/bin/grep"', which _always_ failed.
3401 (AC_PROG_SED): Ditto bogus PATH fix.
3402 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
3403 requires that grep correctly supports _multiple_ `-e' options, rather
3404 than stating only that grep should accept `-e'.
3406 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3408 Port to C99, which requires that 'exit' be declared.
3410 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
3411 to ensure that stdlib.h is included.
3412 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
3413 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
3414 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
3415 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
3416 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
3417 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
3418 when using 'exit' in a test; C99 requires that 'exit' be declared.
3420 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
3422 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
3423 now prefers 'grep' implementations that accept -e.
3424 (Limitations of Usual Tools): Describe problems of traditional
3425 egrep and fgrep with long input lines, and of traditional grep
3426 with -e.
3427 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
3428 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
3429 All callers changed. Append /usr/xpg4/bin to the PATH, for
3430 Solaris.
3431 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
3432 the user with complaints about multiple -e options.
3433 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
3434 Define it with AC_PROG_GREP.
3435 * configure.ac (AC_PROG_GREP): Add.
3436 * lib/freeze.mk (GREP): New macro.
3438 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
3440 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
3441 a possible candidate only after all others fail, rather than
3442 consulting it first. This improves backward compatibility by
3443 better reflecting the way shell selection occurred in previous
3444 versions of Autoconf, and should help to avoid triggering latent
3445 problems in other packages, such as the one in Automake where zsh
3446 is not handled robustly:
3447 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
3448 Although it is not Autoconf's responsibility to work around
3449 problems in Automake, it nevertheless makes sense to avoid
3450 introducing unnecessary incompatibilites.
3452 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
3453 Gary V. Vaughan <gary@gnu.org>
3455 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
3456 how deeply nested we are when a suitable tool is found, set the
3457 ac_path_TOOL_found flag.
3458 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
3459 nested we are in this macro. Break out of all 3 nested loops if
3460 ac_path_TOOL_found is set.
3462 2004-04-21 Gary V. Vaughan <gary@gnu.org>
3464 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
3465 of the _AS_PATH_WALK loop too if GNU flavor is found.
3467 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
3469 * doc/autoconf.texi (Limitations of Make): Update documentation
3470 for `$<'. New entry `Long lines', based on a report from Simon
3471 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
3472 paragraph about DJGPP, based on a mail from Richard Dawe.
3474 2004-04-20 Paul Eggert <eggert@twinsun.com>
3476 * tests/c.at (C keywords): Don't assume that GCC supports
3477 "restrict" and "inline", as sufficiently-old GCC versions do not
3478 (also, GCC configured to be in pedantic C89 mode does not).
3479 Problem reported by Sumit Pandya in:
3480 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
3482 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
3483 consider -g to work if it generates warnings when plain compiles
3484 don't. Problem reported by Braden McDaniel in:
3485 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
3487 * doc/autoconf.texi (Slashes): New section, to document a problem
3488 reported by Jim Meyering in:
3489 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
3491 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
3492 linker output files before linking, to work around IRIX 6 linker bug.
3493 Problem reported by Rainer Orth in:
3494 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
3496 2004-04-20 Gary V. Vaughan <gary@gnu.org>
3498 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
3499 best tool so far counter rely on the tool path variable name to
3500 avoid checks for one tool being affected by the results of running
3501 the length check on a previous tool.
3503 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
3504 match expression argument, as different greps have different
3505 regular expression flavours.
3506 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
3507 literals.
3508 (AC_PROG_EGREP): Pass 'EGREP$'.
3509 (AC_PROG_GREP): Pass 'GREP$'.
3511 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
3513 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
3514 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
3516 2004-03-29 Paul Eggert <eggert@twinsun.com>
3518 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
3519 Types, Specific Compiler Characteristics, System Services,
3520 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
3521 etc. consistently instead of 'long', 'short', 'unsigned' etc.
3522 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
3523 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
3524 Likewise.
3525 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
3526 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
3527 AC_TYPE_OFF_T): Likewise.
3528 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
3529 Likewise.
3531 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
3532 pacify libtool 1.5.2. Fix quoting problems in sed command.
3534 2004-03-28 Paul Eggert <eggert@twinsun.com>
3536 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
3537 now defines HAVE_DECL_TZNAME if it is declared, when
3538 HAVE_STRUCT_TM_TM_ZONE is not defined.
3539 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
3540 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
3541 for HAVE_TZNAME.
3543 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
3545 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
3546 superfluous backslashing of quotes (") in sed expressions;
3547 thanks to Paul Eggert.
3549 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
3551 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
3552 Fortran compiler is ifort, also added pghpf; thanks to Nelson
3553 H. F. Beebe for the bug report.
3555 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
3557 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
3558 quoted -cmdline argument in Portland Group compiler (bug
3559 reported by Jeffrey J. Barteet).
3561 2004-03-25 Kevin Ryde <user42@zip.com.au>
3563 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
3564 (Run Time): ... here, where it's now mentioned.
3566 2004-03-19 Alexandre Duret-Lutz <adl@gnu.org>
3568 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
3569 inherits from language Autoconf-without-aclocal-m4.
3570 (Customizing autom4te): Adjust example; the cache must now be
3571 disabled for language Autoconf-without-aclocal-m4.
3573 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
3574 Nathanael Nerode <neroden@twcny.rr.com>
3576 * lib/autoconf/programs.m4 (AC_PATH_TOOL, AC_CHECK_TOOL,
3577 AC_CHECK_TOOLS): Warn if a cross-tool is found without
3578 a prefix.
3579 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
3580 AC_CHECK_TARGET_TOOLS): New macros.
3581 * doc/autoconf.texi (Generic Programs): Document
3582 (AC_PATH_TARGET_TOOL, AC_CHECK_TARGET_TOOL,
3583 AC_CHECK_TARGET_TOOLS, and warn for future changes
3584 in the behavior of AC_PATH_TOOL, AC_CHECK_TOOL and
3585 AC_CHECK_TOOLS.
3586 (Specifying Names): Document the reason for these future
3587 behavioral changes.
3588 * tests/mktests.sh: Do not generate tests for the
3589 new macros.
3590 * NEWS: Document these changes.
3592 * doc/autoconf.texi: Avoid macros with unbraced arguments,
3593 they make TeX hang up.
3595 2004-03-15 Paul Eggert <eggert@bogus.example.com>
3597 * NEWS: New macro AC_CHECK_ALIGNOF.
3598 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
3599 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
3600 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
3601 vowel.
3602 (AC_CHECK_ALIGNOF): New macro.
3603 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
3604 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
3605 those for sizeof.
3607 2004-03-03 Paul Eggert <eggert@twinsun.com>
3609 * bin/Makefile.am (edit): Don't use $< in a context where
3610 POSIX doesn't require support for it. Use $@.in instead.
3611 Problem reported by Anthony N. Frasso in
3612 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
3613 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
3615 2004-02-23 Gary V. Vaughan <gary@gnu.org>
3617 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
3618 from the next generation of Libtool.
3619 * lib/autom4te.in (Autoreconf-preselections): Ditto.
3621 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
3623 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
3624 is not always thread-safe. Report from Nathanael Nerode.
3626 2004-02-18 Paul Eggert <eggert@twinsun.com>
3628 Fix a dependencies problem, stemming from a Autoconf 2.59 build
3629 problem on QNX reported by Stephen Rasku in
3630 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
3632 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
3633 $(m4sh_m4f_dependencies); this removes a FIXME.
3634 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
3635 (MAINTAINERCLEANFILES): Split into pieces,
3636 one per related section. Add $(srcdir)/wrapper.in.
3638 2004-02-09 Paul Eggert <eggert@twinsun.com>
3640 * doc/autoconf.texi (Setting Output Variables): Emphasize that
3641 AC_SUBST provides no portable way to escape literal newlines.
3643 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
3644 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
3645 Darwin uses -lcrt2.o and there's little point to cataloging all
3646 the system variants. Partial fix reported by Andreas Waechter in:
3647 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html

3671 Eric Sunshine <sunshine@sunshineco.com>
3672 Paul Eggert <eggert@twinsun.com>
3674 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
3675 (AS_INIT): Output shell initialization there. Removed optional
3676 parameter. Expand _AS_SHELL_FN_SPY.
3677 (AS_INIT_WITH_SHELL_FN): Removed.
3678 (_AS_SHELL_FN_SPY): New macro.
3679 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
3680 macros.
3681 (AS_SHELL_SANITIZE): Remove loop to find better shell
3682 and documentation for the parameter.

3686 (AS_REQUIRE_SHELL_FN): Require shell functions when
3687 it is used.
3688 (_AS_LINENO_WORKS): Put around braces, we do not
3689 trigger the bash bug anymore.
3690 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
3691 use AS_INIT_WITH_SHELL_FN.
3692 * bin/autoconf.in, tests/wrapper.in: Regenerated.
3694 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

3702 * lib/autoconf/headers.m4 (AC_USG, AC_MEMORY_H,
3703 AC_DIR_HEADER): Use AU_DEFUN's third parameter.
3704 * lib/autoconf/lang.m4 (AC_LANG_SAVE): Likewise.
3705 * lib/autoconf/programs.m4 (AC_RSH): Likewise.
3706 * lib/autoconf/specific.m4 (AC_HAVE_POUNDBANG,

3722 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
3723 2003 (except 1997) to the list of copyright years. This undoes
3724 the 2003-05-22 change, which removed the older years from the list.
3725 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
3727 2004-01-27 Gary V. Vaughan <gary@gnu.org>

3738 _AC_PROG_GREP, and AC_PROG_SED.
3739 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
3740 longest input length accepted by a command.
3741 (AC_PROG_SED): Use it.
3742 * doc/autoconf.texi (Particular Programs): Document the changes.
3743 * NEWS: Updated.
3745 2004-01-27 Paul Eggert <eggert@twinsun.com>
3747 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.
3748 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
3749 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
3750 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
3752 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
3753 bin/autoconf.in, config/Makefile.in, config/config.guess,
3754 config/config.sub, config/install-sh, config/mdate-sh,
3755 config/mkinstalldirs, config/texinfo.tex, doc/Makefile.in,
3756 lib/Makefile.in, lib/Autom4te/Makefile.in,
3757 lib/autoconf/Makefile.in, lib/autoscan/Makefile.in,

3769 2004-01-26 Paul Eggert <eggert@twinsun.com>
3771 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
3772 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
3773 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
3774 not <inttypes.h>. Problem reported by Tim Mooney in
3775 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
3776 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
3777 Likewise.
3779 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
3780 otherwise "make check" fails because it forbids cmp (I guess
3781 because cmp treats files as binary on DOS-like systems).
3783 * tests/mktests.sh: Update copyright date to 2004, since some tests
3784 have changed in 2004.
3786 2004-01-23 Gary V. Vaughan <gary@gnu.org>
3788 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
3789 non-truncating sed or gsed program in PATH.
3790 * tests/acprograms.at: Add it.
3791 * doc/autoconf.texi (Particular Programs): Document it.
3792 * NEWS: Updated.
3794 2004-01-15 Paul Eggert <eggert@twinsun.com>
3796 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
3797 -std1 disables some useful extensions on Tru64. Problem reported
3798 by N. Lichtmaier in
3799 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
3801 2004-01-14 Paul Eggert <eggert@twinsun.com>
3803 * doc/autoconf.texi (Programming in M4sh): Document that
3804 AS_MKDIR_P succeeds if the destination is a symbolic link
3805 to an existing directory.
3806 (Limitations of Usual Tools): Note that mkdir -p might not
3807 succeed on symlinks to directories.
3809 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
3811 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
3812 * bin/autoheader.in: Grammar fix in message.
3813 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):
3814 Test for dir before calling mkdir -p. (trivial changes)
3816 2004-01-13 Eric Blake <ebb9@byu.net>
3818 * doc/autoconf.texi (Obsolete Macros): In AC_TRY_COMPILE and
3819 AC_TRY_LINK, s/AC_LANG_SOURCE/AC_LANG_PROGRAM/. (trivial change)
3821 2004-01-10 Jim Meyering <jim@meyering.net>
3823 * doc/autoconf.texi (Running the Preprocessor): Correct grammar.
3825 2004-01-09 Paul Eggert <eggert@twinsun.com>
3827 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
3828 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
3829 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
3830 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
3831 AC_COMPILE_IFELSE, since we now assume our caller invokes
3832 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
3833 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
3834 of AC_RUN_IFELSE; this avoids the warning mentioned above.
3835 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
3837 2004-01-07 Paul Eggert <eggert@twinsun.com>
3839 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
3840 `"'...'"`, as it's confusing (and I suspect it may not work on
3841 some platforms). The code was incorrect anyway, as it assumed
3842 that \$ evaluated to itself in that context. Reported by
3843 Alexandre Duret-Lutz.
3845 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
3847 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS
3848 and _LT_AC_TAGCONFIG.
3850 2004-01-06 Paul Eggert <eggert@twinsun.com>
3852 * doc/autoconf.texi (One Macro Call): Fix an incorrect
3853 example, and add more examples. Reported by Eric Sunshine.
3855 2004-01-05 Paul Eggert <eggert@twinsun.com>
3857 * doc/autoconf.texi (Limitations of Usual Tools):
3858 Remove warning against "rm -fr" introduced yesterday; it
3859 was a false alarm.
3861 * bin/Makefile.am (autoconf, autoheader, autom4te, autoreconf,
3862 autoscan, autoupdate, ifnames): Don't use chmod -w.
3863 * lib/Makefile.am (autom4te.cfg): Likewise.
3864 * doc/autoconf.texi (Limitations of Usual Tools): Warn against
3865 "chmod -w".
3867 2004-01-04 Paul Eggert <eggert@twinsun.com>
3868 Paolo Bonzini <bonzini@gnu.org>
3870 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Speed up sed scripts
3871 by doing lineno substitution only on lines containing "$LINENO".
3873 2004-01-04 Paul Eggert <eggert@twinsun.com>
3875 * lib/autoconf/general.m4 (AC_ARG_PROGRAM):
3876 Use "rm -f" to remove conftest.sed, not plain "rm".
3877 Bug reported by David Relson in
3878 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
3880 * Makefile.am (autom4te-update):
3881 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.
3882 * Makefile.maint (my-distcheck, do-po-update): Likewise.
3883 * doc/autoconf.texi (Guidelines): Likewise.
3884 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Likewise.
3885 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Likewise.

3888 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): Likewise.
3889 * tests/Makefile.am (clean-local): Likewise.
3890 * tests/tortue.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS,
3891 srcdir): Likewise.
3892 * doc/autoconf.texi (Limitations of Usual Tools):
3893 Warn against "rm -fr".
3895 2004-01-03 Paul Eggert <eggert@twinsun.com>
3897 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
3898 -c -o might not work. From a suggestion by Kevin Ryde.
3899 (C Compiler, Generating Sources, Limitations
3900 of Usual Tools, Limitations of Make, Making testsuite Scripts):
3901 Don't put '-o' after non-options, as POSIX doesn't allow this.
3902 Mention that cc's name might be gcc or c89 or whatever.
3904 2004-01-04 Kevin Ryde <user42@zip.com.au>
3906 * doc/autoconf.texi: Add various further index entries.
3908 2003-12-29 Paul Eggert <eggert@twinsun.com>
3910 * bin/autoreconf.in (autoreconf_current_directory):
3911 Fix typo: mkdir without umask arg.
3913 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
3915 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
3916 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
3917 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
3918 explanation clearer.
3920 2003-12-24 Andreas Schwab <schwab@suse.de>
3922 * doc/autoconf.texi (Default Includes): Fix misspelling of
3923 AC_INCLUDES_DEFAULT.

3927 * configure.ac: Test if sh -n works.
3928 * configure: Regenerate.
3929 * tests/atlocal.in: Store the result here.
3930 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Extracted from
3931 tools.at, looking in atlocal's ac_cv_sh_n_works instead
3932 of explicitly testing.
3933 (AT_CHECK_PERL_SYNTAX): Moved from tools.at.
3934 (AT_CHECK_AUTOCONF): Test for the configure script syntax.
3935 * tests/tools.at (Syntax of the shell scripts): Simplify
3936 using AT_CHECK_SHELL_SYNTAX.
3937 (Syntax of the Perl scripts): Remove definition of
3938 AT_CHECK_PERL_SYNTAX.

3943 stderr to /dev/null.
3944 * bin/autoconf.in: Regenerate.
3945 * bin/wrapper.in: Regenerate.

3949 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE):
3950 Extracted from AS_SHELL_SANITIZE.
3951 (_AS_SHELL_FN_WORK, AS_INIT_WITH_SHELL_FN): New
3952 macros.
3953 (AS_SHELL_SANITIZE): Move reinvocation code from
3954 _AS_LINENO_WORKS, use it to find out if shell
3955 functions work.
3956 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
3957 does not work.
3958 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.
3959 (AS_REQUIRE_SHELL_FN): Test that AS_INIT_WITH_SHELL_FN

3973 them on the fly.
3975 2003-11-24 Akim Demaille <akim@epita.fr>
3977 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

4010 the expanded body, consistently with other macros such as AC_USG.
4012 2003-11-17 Paul Eggert <eggert@twinsun.com>
4014 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put at least 14 bytes
4015 into the initial confdefs.h, to work around a bug in NextStep 3.3
4016 patch 3 reported by Eric Sunshine.
4018 2003-11-15 Kevin Ryde <user42@zip.com.au>
4020 * doc/autoconf.texi (Using System Type): Revise, showing $host rather
4021 than $target since the latter is not usual, add guidelines on when to
4022 use or not use the system type.
4024 2003-11-12 Derek Price <derek@ximbiot.com>
4026 * doc/autoconf.texi (Limitations of Usual Tools): Fix what looks like a
4027 typo misrepaired by an auto-spellcheck.

4046 * lib/autoconf/status.m4 (_AC_SRCPATHS): Fix use of AS_SET_CATFILE

4055 2003-11-05 Kevin Ryde <user42@zip.com.au>

4199 Problems reported by Eric Sunshine.
4201 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
4203 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted

4228 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
4229 cache variable instead of $G77 to decide whether to include -O2,
4230 since $G77 is specific to Fortran 77.

4237 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
4239 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
4240 arguments so that it can be used with syntax identical to
4241 AC_PROG_F77, and so that we can more easily decide to
4242 remove/deprecate the DIALECT optional argument in the future if it
4243 proves troublesome.
4244 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for
4245 non-freeform-supporting compilers. Document freeform flags.

4259 2003-10-03 Akim Demaille <akim@epita.fr>
4261 * configure.ac: Quotation and formatting changes.

4309 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
4310 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
4311 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
4312 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
4314 2003-09-26 Akim Demaille <akim@epita.fr>
4316 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4317 directory for AC_CONFIG_COMMANDS' first argument exists.
4318 This makes valid the invocation of _AC_SRCPATH that follows.
4319 Reported by Eric Sunshine.
4320 * doc/autoconf.texi (Configuration Commands): Adjust.
4322 2003-09-26 Akim Demaille <akim@epita.fr>
4324 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
4325 Reported by Ralf Corsepius.

4329 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
4330 arguments.
4331 Actually, use AU_ALIAS.
4332 From Bruno Haible.

4343 The test suite are sometimes assigning timings incorrectly.
4344 Reported by Henk Krus.
4345 Diagnosed by Nicolas Joly.
4347 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
4348 AT_help_all.
4349 Instead of making AT_help a sequence of assignments to grow
4350 $at_help_all, just make AT_help_all be the growing contents of
4351 $at_help_all, and make a single assignment in...
4352 (AT_INIT): here.
4353 (at_times_skip): Flip the meaning and rename as...
4354 (at_times_p): this.
4355 (AT_INIT): When summarizing the test that ran, remove
4356 $at_times_file after use, and check it is present before trying to
4357 use it.
4359 2003-09-25 Akim Demaille <akim@epita.fr>
4361 Version 2.57d.
4363 * bin/Makefile.am (edit): Handle '@configure_input@'.

4365 (ifnames): chmod -w.
4366 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
4367 executables, not bin/ executables! Otherwise all the magic needed
4368 to find non installed files is turned off. This caused a failure
4369 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
4370 as found in its environment (sent by tests/autoreconf): pointing
4371 to bin/autom4te that could not find its files.
4372 * tests/mktests.sh: Force the replacement of generated files, for
4373 the sake of "mv" program that are interactive when overwriting a
4374 -w file.

4380 versus test -L issues.
4382 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
4383 Paul Eggert <eggert@twinsun.com>
4385 Trivial change to support GCC's configuration procedure.
4386 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
4387 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
4388 about inconsistency if the preprocessor is set to give errors for
4389 any warning.
4390 * doc/autoconf.texi (C Compiler Characteristics): Document this.
4392 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>

4415 * doc/autoconf.texi (Header Portability): linux/random.h.
4416 From Peter Hendrickson.
4418 2003-09-10 Akim Demaille <akim@epita.fr>
4420 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
4421 willing to edit the output files.
4423 2003-09-10 Akim Demaille <akim@epita.fr>
4425 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
4426 and AC_FC_FREEFORM.
4427 * tests/mktests.sh: Skip AC_FC_SRCEXT.
4428 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
4430 2003-09-09 Akim Demaille <akim@epita.fr>

4445 From a suggestion by Ian Lance Taylor in
4446 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
4448 2003-09-05 Paul Eggert <eggert@twinsun.com>
4450 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
4451 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
4453 2003-09-04 Akim Demaille <akim@epita.fr>
4455 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
4456 AC_FUNC_WAIT3.
4458 2003-09-04 Akim Demaille <akim@epita.fr>
4460 * bin/autom4te.in: Use &fatal where more appropriate than &error.
4461 (freeze): When exiting, use $exit_code.
4462 * lib/autoconf/fortran.m4: Comment changes.
4464 2003-09-04 Akim Demaille <akim@epita.fr>
4466 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
4468 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
4470 Add support for newer Fortran dialects. The F77 interface is
4471 unchanged, and continues to support Fortran 77. New FC macros
4472 correspond to all the old F77 macros, with output variables FC,
4473 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
4474 available dialect, but older dialects can be specified. There are
4475 new macros AC_FC_SRCEXT to set the source extension, and
4476 AC_FC_FREEFORM to accept free-form source files.
4478 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
4479 New macros.
4480 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

4496 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
4497 Rewrite in terms of the above.
4498 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
4499 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.

4505 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
4506 Document problems with timestamp resolution that 'make', 'cp -p', and
4507 'touch -r' have.
4509 2003-08-27 Akim Demaille <akim@epita.fr>
4511 * tests/m4sugar.at (cross_warning): Make sure to enable the
4512 output, so that we can track spurious m4sugar output.

4514 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
4515 are defaulted by AT_CHECK anyway.
4516 Use AT_CHECK_AUTOM4TE.
4517 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
4518 missing dnl.
4520 2003-08-27 Akim Demaille <akim@epita.fr>
4522 * bin/autoheader.in: Issue the "Using auxiliary..." message only
4523 when -Wobsolete is set.

4584 2003-08-21 Akim Demaille <akim@epita.fr>
4586 * lib/Autom4te/General.pm (&file_name_is_absolute): Remove.
4587 (&verbose): Remove.
4588 (&getopt): Adjust the note and verb channels, depending upon
4589 --verbose.
4590 * bin/autoheader.in, bin/autom4te.in, bin/autoscan.in,
4591 * bin/autoupdate.in: Adjust.
4592 Use &verb, not &verbose.
4594 2003-08-21 Akim Demaille <akim@epita.fr>
4596 * bin/autoheader.in (&parse_args): Use &parse_warnings and
4597 &parse_WARNINGS.
4598 ($help): Use Autom4te::ChannelDefs::usage.
4599 * bin/autoscan.in: Use Autom4te::ChannelDefs.
4600 * lib/Autom4te/General.pm: Don't export error: you don't own it.
4602 2003-08-21 Akim Demaille <akim@epita.fr>
4604 First stab at preserving warnings between calls to autom4te,
4605 including when the cache is used.
4607 There are still several issues: (i) there are too many runs of m4
4608 (one for include, one for warnings, and some more), (ii) warnings
4609 spreading on several lines are not handled gracefully, (iii) the
4610 code meant to have the call stack display for errors does not work
4611 (its handling should move from m4 to autom4te).
4613 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
4614 Use them.
4615 (@preselect): Add m4_warn.
4616 ($exit_status): Remove, use $exit_code.
4617 ($help): Use Autom4te::ChannelDefs::usage.
4618 (&handle_m4): No longer define the m4_warnings.
4619 At each run, extract and report the warnings.
4620 Always cache the result, including if the exit status is on
4621 failure, since if nothing changes, we should result in the same
4622 failure, hence we can use the cache.
4623 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
4624 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
4625 Remove.
4626 (m4_warn): Redefine as a do-nothing: it is its invocation that
4627 matters, as warnings are now reported via traces.
4628 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
4629 the contents of m4_warn: make it _call_ m4_warn, so that tracing
4630 the latter reveals calls to the former.
4632 Adjust the tests.
4634 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
4636 2003-08-21 Akim Demaille <akim@epita.fr>
4638 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):
4639 Use them.
4641 2003-08-21 Akim Demaille <akim@epita.fr>
4643 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
4644 forward order.
4645 * lib/Autom4te/ChannelDefs.pm: Doc typos.
4646 (&parse_warnings): Accept a list of warning requests.
4647 (&usage): Return a string, not a side effect.
4648 (cross): New warning category.
4650 2003-08-21 Akim Demaille <akim@epita.fr>
4652 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
4653 (&require_configure_ac): Accept an optional directory argument.
4654 ($configure_ac): Remove.
4655 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
4656 (&catfile): Remove.
4657 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
4658 * bin/autoscan.in: Adjust.
4660 2003-08-20 Akim Demaille <akim@epita.fr>
4662 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
4663 Reported by Alexandre Duret-Lutz.
4665 2003-08-20 Akim Demaille <akim@epita.fr>
4667 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
4668 * bin/autom4te: Adjust.
4669 In particular, be Autoconf tools are really silent when properly
4670 working, bind the verbosity of the 'note' channel to $verbose.
4671 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
4672 (&xsystem, &contents): Remove, since they are exported by...
4673 * lib/Autom4te/FileUtils.pm: this.
4674 More perldoc.
4675 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
4676 * lib/Autom4te/FileUtils.pm: here.
4678 2003-08-20 Akim Demaille <akim@epita.fr>
4680 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
4681 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,
4682 from CVS Automake.
4684 2003-08-20 Akim Demaille <akim@epita.fr>
4686 * Makefile.am (automake_cvsweb, automake_cvsargs, autom4te_files)
4687 (autom4te-update): New.
4688 * Makefile.cfg (update): Bind autom4te-update.
4690 2003-08-19 Derek Price <derek@ximbiot.com>

4693 (PARSE_ARGS_BEGIN): New section for option parsing related
4694 initialization.

4702 * GNUmakefile, Makefile.maint: Update from CVS Coreutils.
4704 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
4706 * lib/autom4te.in (Automake-preselections): Preselect
4707 AC_CONFIG_LIBOBJ_DIR, AC_CONFIG_LINKS, m4_include,
4708 and m4_sinclude.
4710 2003-08-19 Alexandre Duret-Lutz <adl@gnu.org>
4712 * lib/autom4te.in (Autoconf): Move all args except aclocal.m4? into ...

4714 * doc/autoconf.texi (autom4te Invocation): Mention
4715 Autoconf-without-aclocal-m4.

4720 RUN-IF-PASS optional arguments.

4731 2003-08-14 Derek Price <derek@ximbiot.com>
4733 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
4734 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
4735 shorter column three. Add DESCRIPTION to log file content.
4737 2003-08-13 Derek Price <derek@ximbiot.com>
4739 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
4740 output.
4742 2003-08-12 Derek Price <derek@ximbiot.com>
4744 * lib/autotest/general.m4 (AT_CHECK): Use new _AT_CHECK API.
4745 (AT_CHECK_NOESCAPE): Move core functionality to...
4746 (_AT_CHECK): ...this new macro.
4748 2003-08-07 Derek Price <derek@ximbiot.com>
4750 * lib/autotest/general.m4 (AT_CHECK): Move core functionality...
4751 (AT_CHECK_NOESCAPE): ...to this new macro.
4753 2003-07-31 Paul Eggert <eggert@twinsun.com>
4755 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): Work around a bug
4756 in Bash 2.01. Problem reported by Brian Gough in
4757 <http://mail.gnu.org/archive/html/bug-autoconf/2003-07/msg00106.html>.
4759 2003-07-25 John W. Eaton <jwe@bevo.che.wisc.edu>
4761 * lib/autoconf/fortran.m4 (AC_F77_LIBRARY_LDFLAGS): Also ignore
4762 -lcrt1.o, for OS X. (trivial change)
4764 2003-07-07 Paul Eggert <eggert@twinsun.com>
4766 * lib/autoconf/c.m4 (AC_C_INLINE): Wrap the '#define inline ...'
4767 inside '#ifndef __cplusplus'. Problem reported by
4768 Bob Friesenhahn.
4770 2003-07-06 Bill Clarke <llib@computer.org>
4772 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
4773 'long', not 'int', for benefit of Sun's recent C++ compilers
4774 (trivial change). See:
4775 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
4776 (This really should be 'intptr_t', not 'long', but that would
4777 take more work.)
4779 2003-06-25 Akim Demaille <akim@epita.fr>
4781 * lib/Makefile.am (autom4te.cfg): Make it read only.
4782 Depend on Makefile since it contains substitutions.
4783 From Paolo Bonzini.
4784 * lib/autom4te.in (args): Add local.at? for Autotest args.
4785 This change was made on autom4te.cfg which is generated.
4786 Reported by Raja R. Harinath.
4788 2003-06-25 Akim Demaille <akim@epita.fr>
4790 * doc/autoconf.texi (Header Portability): sys/mount.h.
4791 From Gareth McCaughan.
4793 2003-06-23 Akim Demaille <akim@epita.fr>
4795 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
4796 not all of them. This fixes 1. the fact that when testing
4797 Autoconf there are many many config.log, 2. the incorrect use of
4798 top_srcdir to find config.log.
4799 Don't mix the detailed output of failed test with the summary of
4800 failures. Rather, append detailed log afterwards.
4802 2003-06-23 Akim Demaille <akim@epita.fr>
4804 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
4805 always run: output config.log on $at_group_log.
4807 2003-06-23 Akim Demaille <akim@epita.fr>
4809 * tests/torture.at (#define header templates): Don't use quotes in
4810 C++ comments as it puzzles Emacs' sh font-lock-mode.
4812 2003-06-23 Akim Demaille <akim@epita.fr>
4814 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
4815 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
4816 * tests/atspecific.m4: Rename as...

4819 * tests/local.at: here.
4820 * tests/Makefile.am: Adjust.
4821 * doc/autoconf.texi (testsuite Scripts): Adjust.
4823 2003-06-21 Kevin Ryde <user42@zip.com.au>
4825 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
4826 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
4827 ensuring we add -std1 for full-ANSI.
4829 * doc/autoconf.texi (hdrindex): New macro.
4830 Add index entries for portability of various standard header files.
4832 2003-06-20 Akim Demaille <akim@epita.fr>
4834 * configure.ac: Bump to 2.57b.
4836 2003-06-20 Akim Demaille <akim@epita.fr>
4838 Version 2.57a.
4840 2003-06-20 Akim Demaille <akim@epita.fr>

4843 Reported by Marc Espie as PR/233.
4845 2003-06-20 Akim Demaille <akim@epita.fr>
4847 * lib/autotest/general.m4: Use at_times_file only if used.
4848 From Nicolas Joly.

4852 * config/config.guess, config/config.sub, config/elisp-comp,
4853 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
4854 Update from masters.
4856 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
4858 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
4859 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
4860 (TEST_SCRIPT): New diversion.
4861 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
4862 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
4863 (AT_INIT): Support for expected failures.
4865 2003-06-02 Akim Demaille <akim@epita.fr>
4867 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
4868 changes.
4869 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
4870 Autoconf nor Automake.
4871 (&contents): New, from Automake.
4872 PODify.
4874 2003-05-28 Paul Eggert <eggert@twinsun.com>
4876 * NEWS, doc/autoconf.texi (Particular Functions),
4877 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
4878 is the inverse of localtime.
4880 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
4882 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
4883 (handle_exec_errors): New function. Work around $! being
4884 altered by WEXITSTATUS.
4885 (xqx, xsystem): Use handle_exec_errors.
4887 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
4889 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
4890 Do not call `_exit()', simply modify `$?'.
4891 (xsystem): Reset $! before running system, and check it afterward.
4892 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
4893 63 for version mismatches.
4895 2003-05-23 Akim Demaille <akim@epita.fr>
4897 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
4898 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
4899 the middle of a line).
4900 * lib/m4sugar/m4sugar.m4: Likewise.
4901 Remove useless spaces in comments.
4903 2003-05-23 Akim Demaille <akim@epita.fr>
4905 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
4906 exit 63, so that we (or Automake's "missing") can tell the
4907 difference with a plain failure.
4908 * doc/autoconf.texi (Notices): Adjust.
4910 2003-05-23 Akim Demaille <akim@epita.fr>
4912 * Makefile.am, bin/Makefile.am, config/Makefile.am,
4913 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
4914 White spaces cleanup.
4916 2003-05-22 Jim Meyering <jim@meyering.net>
4917 Paul Eggert <eggert@twinsun.com>
4919 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
4920 Remove `#include <stdlib.h>' from the list; we should never
4921 make confdefs.h include <stdlib.h> or <cstdlib>, because the
4922 resulting namespace pollution would cause other tests to fail.
4923 Configure scripts run with some older versions of g++ and HP's
4924 aCC would fail due to such an #include. Problems reported by
4925 Matthew Mueller in <http://bugs.debian.org/120704> and by
4926 Keith Bostic in
4927 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
4928 In the test, use the test declaration before including <stdlib.h>,
4929 as that's closer to how it'll be used.
4931 2003-05-23 Akim Demaille <akim@epita.fr>
4933 * doc/autoconf.texi (Header Portability): ucred.h.
4934 From Ian Redfern.
4936 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
4938 Overhaul Autotest's logging: generate separate log files
4939 in testsuite.dir/NNN/testsuite.log, and append them to
4940 testsuite.log instead of re-running the test verbosely.
4942 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
4943 file descriptor, write 0 to at_status_file instead of setting
4944 at_status=0, initialize some new variables (at_status_file,
4945 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
4946 to rerun the tests, instead append the at_group_log to the
4947 at_suite_log when a test fails.
4948 (AT_SETUP): pipe the test case's output into at_tee_pipe,
4949 with the AS_MESSAGE_LOG_FD redirected to stdout.
4950 (AT_CLEANUP): save the output status in $at_status_file
4951 and restore it, redirect the AS_MESSAGE_LOG_FD back to
4952 its original place.
4953 (AT_CHECK): since tests are run with a redirected stdout,
4954 and used to be re-run in verbose mode, turn some $at_verbose
4955 into echo, and don't redirect the output of testing stdout
4956 and stderr.
4958 * lib/autotest/autoconf.texi (testsuite Scripts): Update
4959 the name of the debugging directory and information about
4960 its contents.
4962 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
4964 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
4965 parameter.
4967 2003-05-22 Akim Demaille <akim@epita.fr>

5035 Reported by Sander Niemeijer.
5036 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.

5038 AC_INCLUDES_DEFAULT.
5040 2003-05-17 Akim Demaille <akim@epita.fr>
5042 * lib/autoconf/specific.m4: Include signal.h and unistd.h.

5044 Reported by Werner LEMBERG and Debian Bug 190886.
5046 2003-05-16 Akim Demaille <akim@epita.fr>
5048 * lib/m4sugar/m4sh.m4 (_AS_UNSET_PREPARE): s/FOO/as_foo/ to avoid
5049 user name space clashes.
5050 Reported by Bruno Haible.
5052 2003-05-16 Akim Demaille <akim@epita.fr>
5054 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
5055 * bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in (BEGIN): Make

5057 Reported by Martin Mokrejs.
5059 2003-05-14 Akim Demaille <akim@epita.fr>

5077 and truncate.
5079 2003-05-06 Akim Demaille <akim@epita.fr>
5081 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5082 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5083 by aclocal.m4 is changed it might require the importing of another
5084 m4 extension file, i.e., aclocal must be run.
5086 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5087 (&parse_args): Use --force with aclocal if required and supported.
5088 (&autoreconf_current_directory): Use &run_aclocal.

5095 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5096 argument instead of a file name, so that the request file remains
5097 open during the whole autom4te run.
5098 ($icache_file): New.
5099 (&freeze): Lock the $icache_file.
5101 2003-04-29 Derek Price <derek@ximbiot.com>
5103 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5104 seperator with m4_append_uniq(). It doesn't work.
5105 (AT_CLEANUP): Add `;' to end of at_help_all.
5106 (AT_INIT): Allow --keywords to be specified more than once. When
5107 grepping $at_help_all for keywords, use the field and keyword
5108 seperators to ensure a complete keyword match. Alter at_prev handling
5109 to support the new --keywords behavior.
5111 2003-04-27 Karl Berry <karl@freefriends.org>
5113 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5114 align better with others. I also made some of the individual
5115 entries on one line, for brevity and to make it easier for me to
5116 sort my dir-example file in the Texinfo distribution :).

5183 header causes problems.
5185 2003-03-28 Akim Demaille <akim@epita.fr>
5187 * tests/torture.at (Configuring subdirectories): Require aclocal
5188 1.4, otherwise the test fails, as it does support configure.ac.
5189 This fixes the "test 40 failed" bug reports.
5191 2003-03-28 Akim Demaille <akim@epita.fr>
5193 * doc/autoconf.texi (C Compiler): `#line' portability.
5194 From Paul Eggert and Nelson H. F. Beebe.
5196 2003-03-27 Derek Price <derek@ximbiot.com>
5198 * lib/autotest/general.m4: Eliminate main loop and reorganize test
5199 layout in order to allow scripting around test groups.
5201 2003-03-27 Derek Price <derek@ximbiot.com>

5211 * lib/autoconf/general.m4 (AC_ARG_VAR): Use AS_HELP_STRING instead of
5212 obsolete AC_HELP_STRING.
5213 (AC_HELP_STRING): AU_DEFUN to...
5214 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): ...here.
5215 * tests/m4sh.at (AS_HELP_STRING): New test.
5217 * tests/acgeneral.at: Regenerated.
5219 2003-03-26 Derek Price <derek@ximbiot.com>
5221 * lib/autotest/general.m4: s/DEFAULT/DEFAULTS/ since it makes more
5222 sense. Verbosify the diversion definitions comment.

5226 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to

5260 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
5261 Tru64 make in the "target lookup" section.
5262 (Automake): Automake 1.5+ no longer requires special tools to be
5263 present on the developer's host.
5265 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
5267 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
5268 to a shell that can handle redirection or quoting correctly.

5271 * bin/autom4te.in (BEGIN): Likewise.
5272 * bin/autoreconf.in (BEGIN): Likewise.
5273 * bin/autoscan.in (BEGIN): Likewise.
5274 * bin/autoupdate.in (BEGIN): Likewise.
5275 * bin/ifnames.in (BEGIN): Likewise.
5277 * bin/ifnames.in: Add final newline to help and version messages.
5279 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
5280 to cope with DOS-style absolute paths, when constructing
5281 ${ac_make}.
5283 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
5284 When constructing paths with IFS=:, quote the path. If we're
5285 constructing a DOS-style absolute path, we don't want to split it
5286 on the colon.
5288 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
5289 in description.
5291 2003-02-25 Pavel Roskin <proski@gnu.org>

5299 2002-09-01 patch by replacing "test -n" with "test -z".
5300 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
5301 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
5303 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
5304 to fix a mismatch between example and discussion.
5306 2003-02-24 Kevin Ryde <user42@zip.com.au>
5308 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
5309 format starting with "-".
5311 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5313 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
5314 is not portable inside Makefile.
5316 2003-02-20 Akim Demaille <akim@epita.fr>
5318 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
5319 compiler says yeah, but preproc says nope, compiler is right.
5320 Conversely, prompt the reader to send a bug report to the
5321 maintainers of the package, not of Autoconf.
5323 2003-02-20 Klee Dienes <kdienes@apple.com>
5325 * bin/autoreconf.in (autoreconf_current_directory): Properly
5326 handle an empty aclocal.m4.

5331 $ac_prefix_program.
5332 From Larry Jones.
5334 2002-12-23 Paul Eggert <eggert@twinsun.com>
5336 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
5337 innocuous variant befor including <limits.h> or <assert.h>. This
5338 works around a bug reported by Albert Chin: HP-UX 11i
5339 (and earlier versions) have a <limits.h> that declares
5340 gettimeofday and many other functions.
5342 2002-12-03 Paul Eggert <eggert@twinsun.com>
5344 Version 2.57.
5346 * NEWS, configure.ac: Update version.
5348 * doc/fdl.texi: Upgrade to FDL version 1.2.
5350 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
5351 nontrivially in main's body, so that f's external declaration is
5352 not optimized away in AIX. This should fix the bug reported by
5353 Martin Frydl in
5354 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
5356 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
5357 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
5358 defined, to support freestanding compilers. This should fix the
5359 bug reported by Momchil Velkov in
5360 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
5362 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
5363 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
5364 obsolete AC_CHECK_TYPE. The missing empty arg was reported

5368 * Makefile.maint (www-gnu): New macro.
5369 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
5370 the location has moved.
5372 2002-12-02 Martin Frydl <martin@systinet.com>
5374 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
5375 \(.*\) match is too long and there is something more to be checked.
5376 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
5378 2002-11-15 Akim Demaille <akim@epita.fr>

5382 * config/install-sh: chmod +x.
5383 From Paul Eggert.
5384 * config/move-if-change: Indenting changes.
5385 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
5386 * configure.ac (AM_INIT_AUTOMAKE): here.
5387 Require 1.7.1.
5389 2002-11-14 Akim Demaille <akim@epita.fr>
5391 Version 2.55.
5393 * config/config.guess, config/config.sub, config/install-sh:
5394 Update from masters.
5396 2002-11-14 Akim Demaille <akim@epita.fr>
5398 * Makefile.maint: Sync with Bison, i.e.:
5399 (po-check): Scan .l and .y files instead of the
5400 .c and the .h files that they generate. This fixes the bug
5401 reported by Tim Van Holder in:
5402 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
5403 Look for N_ as well as for _. Try to avoid matching #define for
5404 N_ and _.
5405 From Paul Eggert.
5407 2002-11-14 Akim Demaille <akim@epita.fr>
5409 * doc/autoconf.texi (C Compiler): Compiling several files at once.
5410 From Paul Eggert and Albert Chin-A-Young.
5412 2002-11-14 Akim Demaille <akim@epita.fr>
5414 * doc/autoconf.texi (C Compiler): Solitary backslashes.
5415 From Paul Eggert and Albert Chin-A-Young.
5417 2002-11-14 Kevin Ryde <user42@zip.com.au>
5419 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
5420 than assigning in main, to avoid HP cc +O3 optimizing it away.
5422 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
5424 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
5425 option. Process --recheck after parsing all options. Pass -q
5426 option to configure on --recheck.
5427 (AC_OUTPUT): Pass -q from configure to config.status.
5428 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
5429 arguments to record.
5430 * doc/autoconf.texi (config.status Invocation): Document
5431 config.status -q option.
5433 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
5435 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
5436 Makefile.in if Makefile.am exists.
5437 (output): Strip `.am' from Makefiles. Don't
5438 output AC_CONFIG_FILES if no Makefiles were found.
5440 2002-11-07 Akim Demaille <akim@epita.fr>
5442 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.
5443 (local_updates): New.
5444 * Makefile.maint: Update, from CVS Bison.
5445 (local_updates): New.
5447 2002-11-06 Akim Demaille <akim@epita.fr>
5449 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
5450 declaration in extern "C" too.
5451 Reported by Roberto Bagnara.
5453 2002-11-06 Akim Demaille <akim@epita.fr>
5455 * tests/torture.at (Configuring subdirectories): Don't use grep
5456 -w.
5457 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
5458 Reported by Ezra Peisach.
5460 2002-11-05 Akim Demaille <akim@epita.fr>
5462 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
5463 Remove.
5464 We _have_ to stop using the old compatibility scheme that tried to
5465 avoid useless backslashes because Libtool 1.4.3 contains a
5466 AC_DEFINE([error_t], [int],
5467 [Define to a type to use for \`error_t' if it is not
5468 otherwise available.])
5469 We _have_ to quote the single quote and backslashes with \. The
5470 old compatibility scheme saw that ` was backslashed, and therefore
5471 did not quote the single quote. Hence before this patch, Autoconf
5472 was not compatible with Libtool.
5474 2002-11-04 Paul Eggert <eggert@twinsun.com>
5476 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
5477 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
5478 LC_NAME, LC_PAPER, LC_TELEPHONE.

5481 2002-11-04 Akim Demaille <akim@epita.fr>
5483 Version 2.54c.
5485 * Makefile.maint (update, cvs-update, po-update, do-po-update):
5486 New.
5487 * config/texinfo.tex: Update.
5489 2002-11-03 Akim Demaille <akim@epita.fr>
5491 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
5492 from...
5493 (&autoreconf): here.
5494 ($help, $make, &parse_args, &autoreconf_current_directory):
5495 Support -m/--make.
5496 * doc/autoconf.texi (autoreconf Invocation): Adjust.
5498 2002-10-31 Bruno Haible <bruno@clisp.org>
5500 * lib/autoconf/functions.m4 (_AC_FUNC_MALLOC_IF): Change message.

5507 2002-10-31 Akim Demaille <akim@epita.fr>
5509 The test suite was no longer checking for trailing envvars and files.
5511 * tests/atspecific.m4 (AC_STATE_SAVE): Don't use quadrigraphs here.
5512 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
5514 2002-10-31 Akim Demaille <akim@epita.fr>
5516 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
5517 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
5518 Make variable, not a shell variable.
5519 Suggested by Bruno Haible.
5521 2002-10-31 Akim Demaille <akim@epita.fr>
5523 * bin/autom4te.in (load_configuration): Reject #args out of any
5524 language.
5526 2002-10-31 Akim Demaille <akim@epita.fr>
5528 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.
5529 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE)
5530 (_AC_RUN_IFELSE): Use it.
5531 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT):
5532 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise.
5533 * lib/autoconf/c.m4 (AC_LANG_SOURCE): Don't include confdefs.h,
5534 inline it.
5536 2002-10-30 Akim Demaille <akim@epita.fr>
5538 * bin/autom4te.in (&parse_args, $help): Support --no-cache.
5539 * doc/autoconf.texi (autom4te Invocation): Adjust.
5540 Suggested by Tim van Holder.
5542 2002-10-29 Paul Eggert <eggert@twinsun.com>
5544 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
5545 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
5546 Problem reported by Bruno Haible.
5548 2002-10-29 Akim Demaille <akim@epita.fr>
5550 * doc/autoconf.texi (Header Templates): Put also in words what the
5551 pictures says to assist free style readers.
5552 (Customizing autom4te): s/--cache=/--cache /.
5554 2002-10-29 Akim Demaille <akim@epita.fr>
5556 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and

5570 * tests/torture.at (Deep Package): New test.

5782 `$ac_configure_args'.

5804 2002-10-22 Akim Demaille <akim@epita.fr>
5806 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there

5808 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
5809 Quote for Perl '' strings, not "".
5810 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
5811 strings.
5813 2002-10-22 Akim Demaille <akim@epita.fr>
5815 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted

5824 Reported by Carlos Velasco.
5826 2002-10-18 Akim Demaille <akim@epita.fr>
5828 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

5861 Because of caching, some files that no longer exist and are no
5862 longer required can still cause errors.
5863 Reported by Alexandre Duret-Lutz.
5865 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
5866 to frozen files in @ARGV, as @ARGV must remain being a list of
5867 files. Rather, at M4 call sites, use this...
5868 (&files_to_options): New function.
5869 (&freeze): Use &error.
5870 (&up_to_date): If a file that was included according to the cache
5871 is no longer there, then the output is out dated.
5872 (&main): Don't even check whether a file is up to date is anyway
5873 --force is given.
5874 * tests/tools.at (autom4te cache): New.
5876 2002-10-16 Akim Demaille <akim@epita.fr>

5879 * bin/autoupdate.in (&parse_args): Kill old options.
5880 * bin/autoreconf.in (&parse_args): Remove dead options.
5881 Factor some code.
5882 (&autoreconf): Report the directories we enter *and leave*, so
5883 that error messages can be easily located, and use GNU Make
5884 format, so that Emacs' compile mode understands us.
5885 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
5886 if some file was changed instead of `print'.
5887 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
5888 (&parse_args): Remove the dead options.

5900 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
5901 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

5920 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
5921 file name to enable parallel executions.
5922 From Sam Varshavchik.
5924 2002-10-08 Akim Demaille <akim@epita.fr>
5926 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
5927 aclocal invocation, as Gettext macros might not be visible to
5928 aclocal.
5929 Instead of blindly running autopoint, scan configure.ac (not the
5930 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
5931 Reported by Paul D. Smith.
5933 2002-10-08 Paul Eggert <eggert@twinsun.com>
5935 Work around problems found when POSIXLY_CORRECT=1 is set.
5936 None of this seems to have anything to do with POSIX, really,
5937 but it's how Perl getopt works.
5938 * bin/autom4te.in (parse_args): Configure GetOpt with
5939 "permute", too.
5940 * doc/autoconf.texi (Invoking autom4te):
5941 --warning -> --warnings.
5942 * lib/autom4te.in: --warning -> --warnings.

5961 2002-09-28 Akim Demaille <akim@epita.fr>
5963 * tests/torture.at (Configuring subdirectories): Be robust to
5964 users who use config.site to require for a cache: in this case,
5965 the two last configure runs, using two different sets of
5966 arguments, trigger a legitimate error.
5968 2002-09-28 Akim Demaille <akim@epita.fr>
5970 * tests/m4sh.at (Functions Support, Functions and return Support):
5971 New.

5984 (tm_zone): Move their rules to...
5985 * lib/autoconf/types.m4: here, using AN_ macros.
5986 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
5987 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
5988 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
5989 * lib/autoconf/programs.m4: here.

6001 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6002 (.m4.m4f): Don't pass --prepend-include, since that's done by
6003 tests/autom4te itself.
6004 * lib/autoscan/Makefile.am: Include freeze.mk.
6005 (autoscan.list): New target --this file is no longer a source.
6006 (autoscan.pre): New file.
6008 2002-09-28 Akim Demaille <akim@epita.fr>
6010 * bin/autoscan.in (@kinds): Make them singular.
6011 Adjust all uses.
6012 (&init_tables): When --debug, report the list of rules to ease
6013 tracking changes in autoscan.list.
6014 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6016 2002-09-28 Akim Demaille <akim@epita.fr>
6018 * lib/autoscan/functions, lib/autoscan/headers,
6019 * lib/autoscan/identifiers, lib/autoscan/makevars,

6024 2002-09-28 Akim Demaille <akim@epita.fr>
6026 * lib/autoscan/functions, lib/autoscan/headers,
6027 * lib/autoscan/identifiers, lib/autoscan/makevars,
6028 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6029 `functions' line is now prefixed with `function:'.
6030 * bin/autoscan.in (&init_tables): Adjust.
6032 2002-09-28 Akim Demaille <akim@epita.fr>
6034 From now on, autoscan files must always map a macro name to a
6035 word: there is no `default' macro for autoscan.
6037 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6038 all.
6039 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6040 explicit.
6042 2002-09-28 Akim Demaille <akim@epita.fr>
6044 * bin/autoscan.in (%c_keywords): Remove.
6045 (&used): Keep only track of the words we might be interested in.
6046 (&output_kind): It is no longer needed to look for non active

6061 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
6062 the tmpdir must be created.
6063 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
6064 dir be in the build tree, instead of $TMPDIR.
6066 2002-09-27 Akim Demaille <akim@epita.fr>
6068 * bin/autoscan.in: Improve the comments.
6069 (&parse_args): Drop obsolete undocumented options.

6078 * doc/autoconf.texi (autoreconf Invocation): Likewise.
6080 2002-09-26 Akim Demaille <akim@epita.fr>
6082 Single suffix rules and seperated dependencies are not portable.
6084 * doc/autoconf.texi (Installation Directory Variables): Update.
6085 (Limitations of Make): Some about `Single Suffix Rules and
6086 Separated Dependencies'.
6087 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6088 (ifnames, autoscan, autom4te): Un-factor into several rules.
6090 2002-09-25 Paul Eggert <eggert@twinsun.com>
6092 * BUGS (Interoperability bugs): New section. Mention libtool
6093 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
6095 2002-09-24 Paul Eggert <eggert@twinsun.com>
6097 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
6098 make handles suffix-rules differently from GNU make.
6100 * bin/Makefile.am (SUFFIXES, .in): Remove.
6101 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
6102 Move the body of the old .in rule here.
6104 2002-09-16 Akim Demaille <akim@epita.fr>
6106 i960 compilers create `b.out' files by default.
6107 Reported by Ralf Corsepius.
6109 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
6110 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
6112 2002-09-13 Paul Eggert <eggert@twinsun.com>
6114 * doc/autoconf.texi (Particular Headers): Remove obsolete
6115 reference to `struct timezone' in the description of
6116 AC_HEADER_TIME.
6118 2002-09-13 Akim Demaille <akim@epita.fr>
6120 Version 2.54.
6122 * config/config.sub, config/config.guess: Update.
6123 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
6124 * Makefile.am: Adjust.
6126 2002-09-13 Akim Demaille <akim@epita.fr>
6128 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
6129 reading config.log when the compiler is rejected.
6130 Suggested by Guido Draheim.
6132 2002-09-13 Akim Demaille <akim@epita.fr>
6134 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6135 (chdir_init) might hang when stat'ing mounted directories.
6136 Reported by Vance Shipley.
6138 2002-09-12 Akim Demaille <akim@epita.fr>
6140 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6141 the lists.
6143 2002-09-12 Akim Demaille <akim@epita.fr>
6145 * doc/autoconf.texi (Defining Symbols): Present two different
6146 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
6147 difference between 1 argument calls, and 2-3 argument calls.
6149 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
6151 * doc/autoconf.texi: Review grammar and punctuation.
6153 2002-09-11 Paul Eggert <eggert@twinsun.com>
6155 * doc/autoconf.texi: Fix minor formatting, spelling, and
6156 grammatical typos.
6157 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6158 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6159 is obsolescent.
6161 2002-09-11 Akim Demaille <akim@epita.fr>
6163 * doc/autoconf.texi (Questions): Rename as...
6164 (FAQ): this.
6165 (Defining Directories): New.
6167 2002-09-09 Akim Demaille <akim@epita.fr>
6169 * doc/autoconf.texi (Making testsuite Scripts): Update.
6170 Suggested by Nishio Futoshi.
6172 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
6174 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
6175 plain `@' is wanted.
6177 2002-09-09 Akim Demaille <akim@epita.fr>
6179 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6180 `duplicates', since the algorithm was too naive and could keep
6181 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6182 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6183 Reported by Ralf Corsepius.
6184 * tests/torture.at (Configuring subdirectories): Exercise these
6185 cases.
6187 2002-09-09 Akim Demaille <akim@epita.fr>
6189 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
6190 looking for a replacement file.
6191 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
6192 directory is relative.
6193 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6194 directory definition.
6195 Reported by Andreas Schwab and Jim Meyering.
6197 2002-09-06 Akim Demaille <akim@epita.fr>
6199 * doc/autoconf.texi (Setting Output Variables): Clarify what
6200 precious variables are.
6201 Suggested by Pontus Skoeld.
6203 2002-09-05 Akim Demaille <akim@epita.fr>
6205 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6206 (ifnames, autoscan, autom4te): Since we don't only depend on
6207 configure.ac variables (such as VERSION etc.), but also on prefix
6208 and so forth, depend on Makefile, not configure.ac.
6209 Reported by Alexandre Duret-Lutz.
6210 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6212 2002-09-05 Kevin Ryde <user42@zip.com.au>
6214 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
6215 doesn't seem to be confined to ia64, just say "some versions".
6217 2002-09-04 Akim Demaille <akim@epita.fr>
6219 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
6220 Automake 1.6c.
6221 * Makefile.am (maintainer-clean-local): Remove.
6222 (MAINTAINERCLEANFILES): Remove COPYING.
6224 2002-09-03 Paul Eggert <eggert@twinsun.com>
6226 * doc/autoconf.texi (Configuration Commands): Remove obsolete
6227 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
6228 Brinkmann.
6230 2002-09-03 Akim Demaille <akim@epita.fr>
6232 * configure.ac: Bump to 2.53d.
6233 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6234 as of today, on Automake's team suggestion.
6236 2002-09-03 Akim Demaille <akim@epita.fr>
6238 Version 2.53c.
6240 2002-09-02 Akim Demaille <akim@epita.fr>
6242 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6243 SITE_MACRO_DIR.
6244 * configure.ac: Disable SITE_MACRO_DIR.
6246 2002-09-02 Jim Meyering <meyering@lucent.com>
6248 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6249 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6250 Also, tweak grammar: s/make sure to/be sure to/.
6252 2002-09-02 Paul Eggert <eggert@twinsun.com>
6254 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6255 directory names are generally preferable to physical names.
6257 2002-09-02 Akim Demaille <akim@epita.fr>
6259 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6260 Reported by Raja R. Harinath.
6261 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6262 * bin/autoupdate.in: Use error instead of die.
6264 2002-09-01 Paul Eggert <eggert@twinsun.com>
6266 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6267 ordinary shell concatenation rather than echo+tr+sed command that
6268 runs afoul of a long-line-related sed bug in Solaris 8.
6270 * bin/autoheader.in (parse_args): --warning -> --warnings.
6272 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6273 stdout, as traditional "ls" does.
6274 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6275 _AC_COMPILER_EXEEXT_O): Likewise.
6276 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6278 * bin/autoconf.as: Add --prepend-include option. This patch was
6279 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6280 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6282 * bin/autoconf.in, configure: Regenerate.
6284 * doc/autoconf.texi (Special Shell Variables): Mention
6285 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6287 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6288 MAILPATH and set PS1, PS2, PS4 to default values, to work
6289 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6290 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6291 the Autoconf documentation specifies; fall back to "unset" only if
6292 this fails. Use a shell for-loop for this rather than an m4 loop,
6293 to shorten the output script.
6295 2002-08-30 Paul Eggert <eggert@twinsun.com>
6297 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6298 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6299 for the CDPATH problem. Document PWD.
6300 (Limitations of Builtins): Document the problem that "cd $foo" and
6301 "ls $foo" may refer to different directories in shells conforming
6302 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6303 example, since the old example is now out of date.
6305 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6306 FOO" and "ls FOO" talk about different directories; this catches
6307 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6308 spaghetti.
6310 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6311 of rolling our own unset.
6312 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6313 in practice we needn't worry about CDPATH if unset doesn't work.
6315 * Makefile.in, aclocal.m4, bin/Makefile.in,
6316 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6317 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6318 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6319 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6320 tests/Makefile.in: Regenerate with Automake 1.6.3.
6322 * config/config.guess, config/config.sub, config/mkinstalldirs:
6323 Update.
6325 * configure: Regenerate with self.
6327 2002-08-30 Kevin Ryde <user42@zip.com.au>
6329 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
6330 default output.
6332 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
6334 * bin/autom4te.in (Request::load): Correctly test for "do" read
6335 failure.
6337 2002-08-29 Akim Demaille <akim@epita.fr>
6339 * lib/Autom4te/General.pm (&xqx): New.
6340 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
6341 hand, which is not portable.
6342 (&error): New.
6343 * bin/autom4te.in: Use them.
6344 Use &error instead of die.
6345 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
6346 Adjust.
6348 2002-08-17 Paul Eggert <eggert@twinsun.com>
6350 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
6351 default list of compilers to try, since it was long ago superseded
6352 by the ksh fc builtin. Suggested by Steven G. Johnson.
6354 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
6356 * doc/autoconf.texi (Invoking autom4te): End the option table,
6357 fixing a bug introduced by the previous patch.
6358 (Limitations of Make): Add a 'target lookup' subentry in the
6359 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
6361 2002-07-29 Mark D. Roth <roth@feep.net>
6363 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
6364 options and use $AUTOM4TE_PATH.
6365 * doc/autoconf.texi: Remove documentation of autom4te
6366 --include-envvar and --site-macro-subdir options and document
6367 use of $AUTOM4TE_PATH.
6368 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
6369 arguments from each language section.
6371 2002-07-29 Paul Eggert <eggert@twinsun.com>
6373 * doc/install.texi: Include copyright symbol in copyright notice.
6375 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
6376 Replace with:
6377 (AM_MAKEINFOFLAGS): New macro.
6378 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
6379 * Makefile.am (INSTALL): Use the new macros.
6380 Use -o rather than --output, since "missing" does not grok --output.
6382 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6384 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
6385 comments do not always work. Never trust the exit status of
6386 `make -k'.
6388 2002-07-24 Kevin Ryde <user42@zip.com.au>
6390 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
6391 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
6393 2002-07-23 Paul Eggert <eggert@twinsun.com>
6395 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
6396 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
6397 apparently treats PATH="nonexistent" as if it contained ".".
6398 Bug reported by Stefan `Sec' Zehl.
6400 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
6402 * doc/autoconf.texi (Limitations of Make): Mention the special
6403 handling of the obj/ directory by BSD make.
6405 2002-07-20 Kevin Ryde <user42@zip.com.au>
6407 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
6408 backslashes.
6410 2002-07-19 Akim Demaille <akim@epita.fr>

6419 2002-07-18 Akim Demaille <akim@epita.fr>
6421 Version 2.53b.
6423 2002-07-18 Akim Demaille <akim@epita.fr>
6425 * config/config.guess, config/config.sub: Update.
6427 2002-07-18 Akim Demaille <akim@epita.fr>
6429 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
6430 Automake's parts.
6432 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): New.
6433 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.
6434 * tests/semantics.at (AC_REPLACE_FUNCS): Adjust.
6436 2002-07-18 Akim Demaille <akim@epita.fr>,
6437 Alexandre Duret-Lutz <duret_g@epita.fr>
6439 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
6440 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

6445 description of the tarname default.

6449 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
6450 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the
6451 latter was not run.
6453 2002-07-17 Akim Demaille <akim@epita.fr>
6455 * lib/Autom4te/General.pm (find_file): Browse the directories in
6456 the order they are given.
6458 2002-07-17 Akim Demaille <akim@epita.fr>
6460 * tests/wrapsh.as, tests/wrappl.as: Merge into...
6461 * tests/wrapper.as: this.
6462 * tests/Makefile.am, configure.ac: Adjust.
6464 2002-07-17 Mark D. Roth <roth@feep.net>
6466 * configure.ac: Add --enable-site-macro-dir option.

6468 * bin/autom4te.in: Add --prepend-include, --include-envvar, and
6469 --site-macro-subdir options.
6470 * bin/autoconf.in: Add --prepend-include option.

6476 macro directory, remove note that include path directories are
6477 used in reverse order, and document --prepend-include option.
6478 * lib/autom4te.in: Use --prepend-include instead of --include.
6479 * tests/wrapsh.in: Use --prepend-include instead of --include.
6481 2002-07-17 Akim Demaille <akim@epita.fr>
6483 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): `_' is allowed in
6484 tarnames.

6487 2002-07-17 Akim Demaille <akim@epita.fr>
6489 * lib/autoconf/functions.m4 (AC_FUNC_REALLOC, _AC_FUNC_REALLOC)
6490 (_AC_FUNC_MALLOC): New.

6517 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
6519 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6520 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
6521 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
6522 so that Emacs setups GNU style for perl-mode and cperl-mode.
6524 2002-06-27 Paul Eggert <eggert@twinsun.com>
6526 * config/install-sh: Quote $src. Prefer || to test's -o option,
6527 as per "Limitations of Builtins".
6528 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
6529 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6531 * tests/mktests.sh: Use grep instead of fgrep, as per
6532 "Limitations of Builtins".
6534 2002-06-15 Paul Eggert <eggert@twinsun.com>
6536 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
6537 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
6538 so that we consistently test the just-built programs.
6539 * tests/wrappl.as: Likewise.
6541 2002-06-12 Paul Eggert <eggert@twinsun.com>
6543 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path

6600 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...

6658 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
6659 from the default list of compilers to try. Suggested by
6660 Kate Hedstrom.
6661 * NEWS: Document the above.
6662 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.

6666 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
6667 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
6668 This improves on an earlier suggestion by H. Peter Anvin.
6670 2002-05-16 Paul Eggert <eggert@twinsun.com>
6672 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
6673 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
6674 Both macros now accept an optional source-dir arg.
6675 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
6677 * NEWS: Document this.
6678 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
6680 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
6681 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
6682 not for GNU extensions; this undoes part of the 2000-11-03 change,
6683 reverting to 2.13-compatible behavior.
6684 Add new optional argument DIR.
6685 (AC_FUNC_FNMATCH_GNU): New macro.
6687 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
6689 2002-05-08 Paul Eggert <eggert@twinsun.com>
6691 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
6692 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
6693 and it causes a 'test' syntax error if it fails.
6694 Bug reported by Stephen Gildea.
6696 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6697 If prototypes are supported, use them to check this at compile-time,
6698 instead of trying to check it at run-time. If we must do a run-time
6699 check, assume that setvbuf is standard when cross-compiling, as
6700 nonstandard setvbuf occurs only on ancient and unlikely hosts.
6701 Bug reported by Paul D. Smith.
6703 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
6704 argument specifying location of getloadavg.c. This removes a
6705 FIXME. This idea was taken from Jim Meyering's implementation in
6706 textutils.
6707 * doc/autoconf.texi (Particular Functions): Document this.
6708 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
6709 that's what the code does; this fixes a bug reported by
6710 Paul D. Smith.
6712 2002-05-03 Akim Demaille <akim@epita.fr>
6714 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
6715 autopoint instead of gettextize.
6716 ($uses_alocal): Rename as...
6717 ($uses_aclocal): this.
6718 * doc/autoconf.texi (autoreconf Invocation): Adjust.
6719 Suggested by Bruno Haible.
6721 2002-05-03 Akim Demaille <akim@epita.fr>
6723 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
6725 2002-04-29 Paul Eggert <eggert@twinsun.com>
6727 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
6728 files to be 1 second older; just set them to be the same time.
6729 Also, sleep 1 second after the first aclocal, to work around
6730 problems with sub-second time stamps on the input files.
6732 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
6734 * doc/autoconf.texi: Mention "set -e -x" lossage
6735 under node "Limitations of Builtins".
6737 2002-04-29 Akim Demaille <akim@epita.fr>
6739 * doc/install.texi: Better wording for setting variables when
6740 running configure.
6741 From Christian Cornelssen.
6743 2002-04-29 Akim Demaille <akim@epita.fr>
6745 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
6746 of lack of $LINENO support, then the test will compare the $LINENO
6747 in testsuite vs. the lineno in the test file. This is wrong, of
6748 course.
6749 Be sure to protect it.
6750 Reported by Patrick Welche.
6752 2002-04-25 Akim Demaille <akim@epita.fr>
6754 * doc/autoconf.texi (Obsolete Macros): Typo.
6755 Reported by Vladimir Volovich.
6757 2002-04-25 Akim Demaille <akim@epita.fr>
6759 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
6760 than some of the input files, hence, on the second run of aclocal,
6761 if some of its input are younger, make them older.
6762 Suggested by Paul Eggert.
6764 2002-04-25 Akim Demaille <akim@epita.fr>
6766 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
6767 Thanks to Paul Eggert.
6769 2002-04-25 Akim Demaille <akim@epita.fr>
6771 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
6772 and ac_subst_vars be sh variables containing the list of
6773 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
6774 DEFAULT diversion.
6775 (_AC_INIT_PREPARE): Use them to log them.
6776 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
6777 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
6778 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
6779 _AC_SUBST_FILES and _AC_SUBST_VARS.
6780 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
6782 2002-04-24 Akim Demaille <akim@epita.fr>
6784 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
6785 autoheader, so that automake does not complain about a missing
6786 config.h.in that was to be created.
6788 2002-04-23 Akim Demaille <akim@epita.fr>
6790 * bin/autoheader.in (parse_args): --warning takes an argument.

6842 * doc/autoconf.texi: Follow the outline suggested in the GNU
6843 Sample Texts sections of the Texinfo 4.2 manual. Most
6844 importantly, this makes sure that the copyright notices appear in
6845 all output formats. You probably need Texinfo 4.2 to generate
6846 the manual now.

6874 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

6902 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):

6951 Don't use the KILL diversion, as it kills spurious output, which
6952 results in failures being hidden.

6955 after the second argument.

7031 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7032 problem with here-document buffer boundaries.
7034 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7035 when reinvoking the shell, to work around problems with installers
7036 who put strange things like "cd" commands in their environments.
7038 2002-03-19 Akim Demaille <akim@epita.fr>
7040 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
7041 From Aaron Ucko.
7043 2002-03-19 Akim Demaille <akim@epita.fr>
7045 * bin/autoscan.in (scan_file): Specify the location in `&used'
7046 invocations.
7047 From Nicolas Joly.
7049 2002-03-19 Akim Demaille <akim@epita.fr>
7051 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7052 From Nishio Futoshi.
7054 2002-03-19 Akim Demaille <akim@epita.fr>
7056 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
7058 2002-03-18 Paul Eggert <eggert@twinsun.com>
7060 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7061 (Limitations of Usual Tools): Add mkdir section.
7063 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7064 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7065 back on AS_DIRNAME to compute prefixes otherwise; this is
7066 roughly what mkinstalldirs does. That way, we need not have
7067 our own filename disassembler. The old disassembler did not
7068 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7070 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7071 Create at_test_all by a series of assignments,
7072 not by a single assignment of a long string. The latter causes ksh
7073 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7074 presumably because of a buffer overrun.
7076 2002-03-14 Paul Eggert <eggert@twinsun.com>
7078 * lib/autotest/general.m4 (at_times_skip):
7079 Renamed from at_times. Now a boolean.
7080 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7081 says 'times: not found'.
7083 2002-03-14 Akim Demaille <akim@epita.fr>
7085 * bin/autoreconf.in (&study_gettextize): New.
7086 (&autoreconf): Handle newest gettextize.
7087 Rerun aclocal if needed.
7088 Suggested by Andreas Schwab.
7090 2002-03-13 Akim Demaille <akim@epita.fr>
7092 * doc/autoconf.texi (Special Shell Variables): More about IFS.
7094 2002-03-13 Akim Demaille <akim@epita.fr>
7096 * doc/autoconf.texi (Header Portability): New.
7097 Add information about stdint.h and inttypes.h from Paul Eggert.
7099 2002-03-13 Akim Demaille <akim@epita.fr>
7101 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
7102 -p'.
7103 From Bob Proulx.
7105 2002-03-12 Akim Demaille <akim@epita.fr>
7107 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
7108 m4_require.
7110 2002-03-11 Andreas Schwab <schwab@suse.de>
7112 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
7113 does not do it if --with-lispdir is given.
7115 2002-03-08 Akim Demaille <akim@epita.fr>
7117 Version 2.53.
7119 2002-03-08 Akim Demaille <akim@epita.fr>
7121 * doc/autoconf.texi (Subdirectories): Clarify that the
7122 subdirectory should exist.
7124 2002-03-08 Akim Demaille <akim@epita.fr>
7126 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
7128 2002-03-08 Akim Demaille <akim@epita.fr>
7130 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7131 aliases the actual variables, and modifications of the former
7132 affect the latter.
7134 2002-03-08 Akim Demaille <akim@epita.fr>
7136 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7137 because of C-c: have m4 output in tmp files, then mv them.
7139 2002-03-08 Akim Demaille <akim@epita.fr>
7141 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
7142 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
7143 * bin/ifnames.in: Copyright update.
7145 2002-03-08 Akim Demaille <akim@epita.fr>
7147 * doc/autoconf.texi (Invoking autom4te): New.
7149 2002-03-05 Akim Demaille <akim@epita.fr>
7151 * doc/autoconf.texi (Specifying Names): Clarification suggested by
7152 Kevin Ryde.
7154 2002-03-05 Akim Demaille <akim@epita.fr>
7156 Version 2.52i.
7158 2002-03-04 Akim Demaille <akim@epita.fr>
7160 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
7161 * lib/autoconf/general.m4 (AC_INIT): More informative error
7162 message for LIBOBJ.
7164 2002-03-04 Akim Demaille <akim@epita.fr>
7166 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
7167 parallel builds.
7169 2002-03-04 Akim Demaille <akim@epita.fr>
7171 * doc/autoconf.texi (Transforming Names): Equality between target
7172 and host is irrelevant.
7173 (Specifying Names, Canonicalizing): Remove all references to the
7174 backward compatibility hooks. Rather, collect them all into...
7175 (Hosts and Cross-Compilation): this new section.
7176 * doc/install.texi (System Type): Ditto.
7177 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7178 that `--host' implies cross-compilation.
7180 2002-03-04 Akim Demaille <akim@epita.fr>
7182 * doc/autoconf.texi (Evaluation Macros): New.
7183 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7184 useless.
7185 (_m4_foreach): Define the variant with immediate evaluation so
7186 that it contains exactly the items, not an expression which
7187 evaluation is the current item.
7188 (m4_re_string, m4_re_word): Don't over quote them.
7190 2002-03-04 Akim Demaille <akim@epita.fr>
7192 Instead of having stacking `shift's evaluated at the end, let
7193 `foreach' loops immediately evaluate them.
7195 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7196 $*. This is the n-th time I change my mind, but hopefully this is
7197 the last...
7198 (m4_lquote): New.
7199 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7200 efficient.
7201 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7202 it was only a hack for m4_text_wrap.
7203 (m4_car2): Remove, replaced by...
7204 (m4_cdr): New.
7205 (_m4_foreach): Adjust.
7206 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7207 m4_bpatsubst for clarification.
7209 2002-03-04 Akim Demaille <akim@epita.fr>
7211 * doc/autoconf.texi (Changequote is Evil): New.
7213 2002-03-03 Kevin Ryde <user42@zip.com.au>
7215 * doc/autoconf.texi (Portable Shell): Mention 32-byte #! length limit
7216 on old systems like SunOS.
7218 2002-03-01 Peter Eisentraut <peter_e@gmx.net>
7220 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
7221 lib/autoconf/functions.m4, lib/autoconf/general.m4,
7222 lib/autoconf/headers.m4, lib/autoconf/lang.m4,
7223 lib/autoconf/programs.m4, lib/autoconf/status.m4: Improve spelling
7224 of messages.
7226 2002-02-28 Akim Demaille <akim@epita.fr>

7229 message to be sent.
7231 2002-02-28 Kevin Ryde <user42@zip.com.au>
7233 * doc/autoconf.texi (Function Portability): Add va_copy and va_list.
7235 2002-02-25 Akim Demaille <akim@epita.fr>
7237 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
7238 From Akinori Musha.
7240 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
7242 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
7243 translate \r\n to \n.
7245 2002-02-07 Akim Demaille <akim@epita.fr>
7247 Version 2.52h.
7249 2002-02-07 Akim Demaille <akim@epita.fr>
7251 Fix Autoconf PR/209.
7252 Also reported by Frank Denis.
7254 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
7256 2002-02-07 Akim Demaille <akim@epita.fr>
7258 Fix Autoconf PR/207:
7259 AC_PREFIX_PROGRAM fails with dashed program names
7261 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7262 variable when looking for the prefix program.
7263 Now it also works for shell variables.
7265 2002-02-07 Akim Demaille <akim@epita.fr>
7267 * doc/autoconf.texi (Limitations of Builtins): More about
7268 case/esac.
7270 2002-02-06 Akim Demaille <akim@epita.fr>
7272 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
7273 case/esac, some shells don't support it.
7274 Reported by Zack Weinberg.
7275 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
7277 2002-02-06 Akim Demaille <akim@epita.fr>
7279 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
7280 sure not to introduce newlines in at_groups.
7281 * lib/autotest/Makefile.am (autotest.m4f): Typo.
7283 2002-02-06 Akim Demaille <akim@epita.fr>
7285 * tests/torture.at (Configuring subdirectories): Skip if aclocal
7286 is not available.
7288 2002-02-05 Paul Eggert <eggert@twinsun.com>
7290 * doc/autoconf.texi (Specific Compiler Characteristics):
7291 Describe HP-UX cc bug workaround more accurately.
7292 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
7293 not unsigned long.
7294 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
7295 cross-compilers, too. This undoes some of the most recent change
7296 to this file.
7298 2002-02-05 Akim Demaille <akim@epita.fr>
7300 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
7301 to make sure they are up to date when `check' is run.
7303 2002-02-05 Akim Demaille <akim@epita.fr>
7305 * doc/autoconf.texi (Making testsuite Scripts): Document
7306 package.m4.
7308 2002-02-05 Akim Demaille <akim@epita.fr>
7310 * lib/freeze.mk: New.
7312 2002-02-05 Akim Demaille <akim@epita.fr>
7314 Implement `autom4te --freeze'.
7316 * bin/autom4te.in (&freeze): New.
7317 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
7318 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
7320 2002-02-05 Akim Demaille <akim@epita.fr>
7322 * bin/autom4te.in (&parse_args): Implement `frozen files are
7323 optional are the sum of the previous files on the command line'.
7324 Also, pass `--reload-state=' on them, so...
7325 (handle_m4): don't.
7326 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
7327 (M4sh): Rely on M4sugar.
7328 (Autotest, M4sh, M4sugar): Use frozen files.
7330 2002-01-31 Akim Demaille <akim@epita.fr>
7332 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
7333 * doc/autoconf.texi (Initializing configure): Adjust.
7335 2002-01-30 Akim Demaille <akim@epita.fr>
7337 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
7338 alphanumeric to `-' instead of `_'.
7340 2002-01-30 Akim Demaille <akim@epita.fr>
7342 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
7343 for plain code, the other for cross-compilation code. The latter
7344 is now run with GCC only.
7345 * doc/autoconf.texi (Compilers and Preprocessors): New.
7347 2002-01-30 Akim Demaille <akim@epita.fr>
7349 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
7350 values.
7351 * doc/autoconf.texi (Initializing configure): Explain how to
7352 change AC_INIT default values.
7354 2002-01-29 Akim Demaille <akim@epita.fr>
7356 * tests/torture.at (Configuring subdirectories): Use configure.in,
7357 so that aclocal 1.4 works.
7358 Reported by Alexandre Duret-Lutz and Larry Schmitt.
7360 2002-01-28 Akim Demaille <akim@epita.fr>
7362 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
7363 needs an argument.
7365 2002-01-28 Akim Demaille <akim@epita.fr>
7367 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
7368 AUTOTEST_PATH *after* it was set.
7369 Don't put `.' in the PATH: the user should be precise and `./' if
7370 needed. In addition, given that the test suite does some `cd', if
7371 `.' is in the path, the `tested programs' sections will report
7372 programs found in the test suite's directory, while during the
7373 tests (performed in their own directory), these programs are no
7374 longer visible. In other words, the results is confusing and
7375 useless.
7376 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
7378 2002-01-24 Akim Demaille <akim@epita.fr>
7380 Version 2.52g.
7382 2002-01-24 Akim Demaille <akim@epita.fr>

7385 * doc/autoconf.texi: Finally add Akim as an author.
7387 2002-01-24 Akim Demaille <akim@epita.fr>
7389 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
7390 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
7391 Bourne. Use /bin/sh.
7392 From Andreas Buening.
7394 2002-01-24 Akim Demaille <akim@epita.fr>
7396 * config/config.guess, config/config.sub, config/texinfo.tex:
7397 Update from masters.
7399 2002-01-24 Akim Demaille <akim@epita.fr>
7401 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
7402 * config/auxdir.m4, config/cond.m4, config/depend.m4,

7404 * config/missing.m4, config/sanity.m4, config/select.m4,
7405 * config/strip.m4: Remove, to ease sync'ing with any version of
7406 Automake.
7408 2002-01-24 Akim Demaille <akim@epita.fr>
7410 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
7411 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
7412 Reported by Geir Ove Myhr.
7414 2002-01-21 Akim Demaille <akim@epita.fr>
7416 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
7418 2002-01-21 Akim Demaille <akim@epita.fr>
7420 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
7421 message on invalid options.
7422 * bin/autom4te.in (parse_args): Don't use
7423 Autoconf::General::getopt with non valid options.
7425 2002-01-17 Jim Meyering <meyering@lucent.com>
7427 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
7428 $ac_cv_exeext so we don't use an old, invalid, cached value.
7430 2002-01-11 Akim Demaille <akim@epita.fr>
7432 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
7433 Meyering.
7434 * doc/autoconf.texi (Function Portability): Document the strnlen
7435 limitation.

7437 * lib/autoscan/functions: Adjust.
7439 2002-01-06 Akim Demaille <akim@epita.fr>
7441 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
7442 package.m4, since is really depends upon configure.ac, not
7443 configure.
7444 * doc/autoconf.texi (testsuite Scripts): Adjust.
7445 * tests/Makefile.am (package.m4): New.
7446 EXTRA_DIST it since its a source.
7448 2002-01-06 Akim Demaille <akim@epita.fr>
7450 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
7451 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
7452 and PACKAGE_BUGREPORT from here...
7453 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
7454 arguments.
7455 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
7456 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
7457 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
7458 * tests/tools.at (autoheader): Adjust.
7459 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
7461 2002-01-06 Akim Demaille <akim@epita.fr>
7463 * bin/autoscan.in (scan_file): Use `&used'.
7465 2002-01-03 Akim Demaille <akim@epita.fr>
7467 * doc/autoconf.texi (Output): Improved wording regarding use of
7468 AC_OUTPUT.
7469 From Olly Betts.
7471 2001-12-18 Kevin Ryde <user42@zip.com.au>
7473 * doc/autoconf.texi (Function Portability): Add notes on sscanf
7474 sometimes needing writable input.
7476 2001-12-17 Jim Meyering <meyering@lucent.com>
7478 * doc/autoconf.texi (New Macros): Tweak wording.
7480 2001-12-14 Akim Demaille <akim@epita.fr>
7482 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
7483 trailing files, don't apply `-rf' to files which might not be
7484 created by configure (core, core.*, and *.core), but just `rm -f'.
7485 Suggested by Jonathan Kamens.
7487 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
7489 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
7491 2001-12-14 Akim Demaille <akim@epita.fr>
7493 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
7495 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
7497 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
7498 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
7499 abs_srcdir, top_srcpath to abs_top_srcdir.
7500 (_AC_OUTPUT_FILES): Adjust.

7513 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
7514 forbidden file descriptors table.
7516 2001-11-26 Akim Demaille <akim@epita.fr>
7518 * bin/autoscan.in (%c_keywords): Build it at top level.
7519 Map to 1 in order to simplify its uses.
7521 2001-11-26 Akim Demaille <akim@epita.fr>
7523 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
7524 Remove $filepath, useless.
7525 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
7526 variables, they are really part of the tokens.
7527 Split the input line on spaces and then look for tokens.
7528 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
7529 because of `lex$U.$(OBJEXT)'.
7530 (&scan_files): Use "@list" instead of join.
7531 * doc/Makefile.am (CLEANFILES): Add *.fns.
7533 2001-11-26 Akim Demaille <akim@epita.fr>
7535 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
7536 Remove, replaced by...
7537 * tests/wrappl.in: Be common for all the Perl executables.
7538 In particular autoscan and autoheader want -I.
7539 * configure.ac: Adjust.
7540 * lib/autoscan/headers: errno.h is portable.
7542 2001-11-26 Akim Demaille <akim@epita.fr>
7544 * bin/autoscan.in (used): New.
7545 Use it.
7547 2001-11-26 Akim Demaille <akim@epita.fr>
7549 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
7550 directives.
7551 (&scan_sh_file): Remove a duplicate pattern.
7552 (&check_configure_ac): Use long options.
7553 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
7555 2001-11-26 Akim Demaille <akim@epita.fr>
7557 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
7558 Before, having a line containing the opening of a multi line
7559 comment made the whole line be ignored.
7561 2001-11-26 Akim Demaille <akim@epita.fr>
7563 * doc/autoconf.texi (Using an Autotest Test Suite): New.
7564 (testsuite Scripts): Be one of its subsection.
7565 (Autotest Logs): New.
7567 2001-11-26 Akim Demaille <akim@epita.fr>
7569 Test groups are now run two directories deeper.
7571 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
7572 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
7573 at_top_builddir.
7574 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
7575 top_srcdir, builddir and top_builddir.
7576 Use `at_*dir' relatively to the directory containing the
7577 suite, use `*dir' when relatively to the current group dir.
7579 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
7581 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
7582 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
7583 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
7584 spelling errors.
7586 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7588 * doc/autoconf.texi (Using System Type): Add an example of `case
7589 $host' usage so people quit using `case $target' everywhere.
7591 2001-11-22 Akim Demaille <akim@epita.fr>
7593 * doc/autoconf.texi (Installation Directory Variables): Englishoes
7594 spotted by Jim Meyering.
7596 2001-11-16 Paul Eggert <eggert@twinsun.com>
7598 This patch implements a `long double' suggestion by Oliver Kiddle.
7600 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
7601 static, to catch errors if the value isn't known at compile-time
7602 and the compiler supports dynamic arrays. Change its name from
7603 `_array_' to `test_array' to avoid potential name clashes.
7604 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
7605 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
7606 better than double. Catch a bug in GCC 2.95.2 x86.
7607 * doc/autoconf.texi (C Compiler): Document the above.
7608 * NEWS: Likewise.
7610 2001-11-13 Akim Demaille <akim@epita.fr>
7612 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
7613 hand.
7614 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
7616 2001-11-13 Akim Demaille <akim@epita.fr>
7618 * lib/autotest/general.m4 (AT_INIT): After having run the test
7619 group, go back to the initial directory, not to at_suite_dir.
7621 2001-11-13 Akim Demaille <akim@epita.fr>
7623 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
7624 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
7625 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
7626 option.
7627 (AT_CHECK_CONFIGURE): Use absolute paths.
7628 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
7629 The problem is still the old one: there is no means in M4 (that I
7630 know about) to create a defining macro, because there is no means
7631 to create `$1' etc., therefore, the defining macro ``swallows''
7632 all the arguments meant to the defined macro.
7634 2001-11-13 Akim Demaille <akim@epita.fr>
7636 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
7637 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
7638 configure.ac.
7639 * tests/aclocal.m4: Remove, as it is no longer used.
7641 2001-11-13 Akim Demaille <akim@epita.fr>
7643 * lib/autotest/general.m4: Change `tests?' into `groups?' in
7644 variable names when referring to a single test group, or to
7645 `suite' when referring to the whole test suite.
7646 `at_last_test' is removed: m4 compute at_format itself.
7647 (at_stdout, at_stder1, at_stderr): New variables.
7648 (AT_CHECK): Use them.
7650 2001-11-13 Akim Demaille <akim@epita.fr>
7652 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
7653 in PATH.
7654 Create `testsuite.dir/003/run' instead of `testsuite.003'.
7655 Do it as soon as a test fails, don't wait till the end of the test
7656 suite.
7657 Don't remove $as_me.[0-9]*, since these files no longer exist.
7659 2001-11-13 Akim Demaille <akim@epita.fr>
7661 * tests/tools.at: Use absolute paths, since we are no longer run
7662 in place.
7664 2001-11-13 Akim Demaille <akim@epita.fr>
7666 Now that tests are running in their own private dir, there is no
7667 need to list the files to remove at the end of tests groups.
7669 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
7670 (AT_data_files, at_data_files): Remove.
7671 (AT_CLEANUP, AT_DATA): Simplify.
7672 (AT_INIT): Adjust.
7673 Remove the group dir if !debug && !failed.
7674 * tests/atspecific.m4: Adjust.
7676 2001-11-13 Akim Demaille <akim@epita.fr>
7678 Start a new layout for Autotest: `testsuite' creates
7679 `testsuite.dir' in which the at-check-line etc. files are to be
7680 found, and `testsuite.dir/003' where the test group 3 is run.
7682 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
7683 at_check_line_file, at_format, at_test_normalized, at_group_dir
7684 are new variables.
7685 Create the directories.
7686 Use absolute paths for at- files.
7687 (AT_CHECK): Adjust.
7689 2001-11-11 Michael Matz <matz@kde.org>
7691 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
7692 (m4_car2): New.
7693 (m4_car): Properly quote arguments.
7695 2001-11-13 Akim Demaille <akim@epita.fr>
7697 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
7698 with stricter rules on LIBOBJS.
7700 2001-11-12 Paul Eggert <eggert@twinsun.com>
7702 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
7703 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
7704 __PROTOTYPES too.
7706 2001-11-12 Akim Demaille <akim@epita.fr>
7708 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
7710 2001-11-12 Akim Demaille <akim@epita.fr>
7712 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
7713 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
7714 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7715 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
7716 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
7717 specify to what the macro should be defined (typically to 1).
7719 2001-11-12 Akim Demaille <akim@epita.fr>
7721 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
7722 From Jim Meyering.
7724 2001-11-12 Akim Demaille <akim@epita.fr>
7726 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
7727 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
7728 definition used by Automake where LEX is +/- "${missing} lex" and
7729 `missing' itself contains variables.
7731 2001-11-12 Akim Demaille <akim@epita.fr>
7733 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
7734 Now that M4sh pushes BODY, the comments were output at the end of
7735 the test suites.
7737 2001-11-08 Akim Demaille <akim@epita.fr>
7739 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
7740 that we can trace macros from aclocal.m4.
7741 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
7742 obsoleted, and redirect to the former anyway.
7743 Reported by Ralf Corsepius.
7745 2001-11-08 Akim Demaille <akim@epita.fr>
7747 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
7748 processed only if present.
7749 * tests/torture.at (Configuring subdirectories): Use autoreconf
7750 instead of successive calls to autoconf.
7751 Add a nonexistent subdirectory to exercise the patch above.
7752 Reported by Ralf Corsepius.
7754 2001-11-08 Kevin Ryde <user42@zip.com.au>
7756 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
7757 doesn't accept .S files.
7759 2001-11-07 Akim Demaille <akim@epita.fr>
7761 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
7762 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
7763 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
7764 * bin/autom4te.in (warn_forbidden): New.
7765 (handle_output): Use it.
7766 Read m4_pattern_forbid with messages.
7768 2001-11-05 Akim Demaille <akim@epita.fr>
7770 * bin/autom4te.in (--normalize): Remove.
7771 * lib/autom4te.in: Adjust.
7773 2001-11-05 Akim Demaille <akim@epita.fr>
7775 * tests/Makefile.am (testsuite): Rename this target as...
7776 ($(TESTSUITE)): this.
7777 From Nicolas Joly.
7779 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
7781 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
7782 the --prefix option, also remove it's argument.
7784 2001-11-05 Akim Demaille <akim@epita.fr>
7786 * doc/autoconf.texi (testsuite Invocation): Update.
7787 (Writing testsuite.at): Update.
7789 2001-11-03 Akim Demaille <akim@epita.fr>
7791 * doc/autoconf.texi: s/@code/@command/ where appropriate.
7793 2001-11-03 Akim Demaille <akim@epita.fr>
7795 * lib/Autom4te/General.pm: (&catfile, &canonfile)
7796 (&file_name_is_absolute): New, wrappers around routines from
7797 File::Spec.
7798 Use and export them.
7799 (&find_configure_ac): Optionally take a directory where to look at.
7800 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
7801 the arguments.
7802 Default @ARGV to `.', not find_configure_ac.
7803 (&autoreconf): Argument is a directory.
7804 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
7805 * doc/autoconf.texi (autoreconf Invocation): Update.
7807 2001-11-03 Akim Demaille <akim@epita.fr>
7809 * lib/Autom4te/General.pm (@export_vars, @export_subs)
7810 (@export_forward_subs): New.
7811 Add basename, dirname, and fileparse.
7812 (@EXPORT): Adjust.
7813 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
7814 Don't look for aclocal flags if we already know aclocal is not
7815 used.
7816 Move aclocal.m4t only if it exists.
7817 Reported by Ezra Peisach.
7819 2001-11-03 Akim Demaille <akim@epita.fr>
7821 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
7822 passed on command line, defaulting to ./configure.ac if present.
7823 (&maybe_autoreconf, File::Find): Remove, unused.
7824 (&autoreconf): If autoconf is not used, don't try to trace.
7826 2001-11-02 Akim Demaille <akim@epita.fr>
7828 * configure.ac: Bump to 2.52g.
7830 2001-11-02 Akim Demaille <akim@epita.fr>
7832 Version 2.52f.
7834 2001-11-02 Akim Demaille <akim@epita.fr>
7836 * config/config.guess, config/config.sub, doc/standards.texi:
7837 * config/lispdir.m4: Update from masters.
7838 * configure.ac: Bump to 2.52f.
7840 2001-11-02 Akim Demaille <akim@epita.fr>
7842 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
7843 Don't run aclocal when aclocal.m4 is not from aclocal.
7844 From Ezra Peisach.
7845 Don't run libtoolize and gettextize if --install is not given.
7847 2001-11-01 Paul Eggert <eggert@twinsun.com>
7849 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
7850 be invoked before _AS_LINENO_PREPARE.
7851 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
7852 than character ranges.
7854 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
7855 invoking AS_BASENAME. Set the locale variables to 'C' if
7856 possible, as POSIX requires this to get the traditional
7857 behavior.
7858 * doc/autoconf.texi (Special Shell Variables): Describe the above.
7860 2001-10-31 Paul Eggert <eggert@twinsun.com>
7862 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
7863 with {}, as that triggers a bug in Bash 2.05.
7865 (_AS_LINENO_PREPARE): Use Sed rather than
7866 Awk. Fix the sed prepass to work even if there are multiple
7867 instances of $LINENO on the same line. Do not substitute for
7868 other variables like $LINENOT. Do not check file dates; such a
7869 check is unreliable on sufficiently fast machines, and removing
7870 the check makes the code simpler and more reliable. Check for
7871 output and chmod failures.
7873 * doc/autoconf.texi (Special Shell Variables): Document
7874 the above.
7876 2001-10-31 Akim Demaille <akim@epita.fr>
7878 * tests/Makefile.am (atconfig): Remove this target, Automake
7879 handles it now.
7881 2001-10-31 Akim Demaille <akim@epita.fr>
7883 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
7884 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
7885 provided, while it is optional.
7886 * configure.ac: Adjust.
7888 2001-10-26 Paul Eggert <eggert@twinsun.com>
7890 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
7891 lib/Autom4te/Struct.pm:
7892 Require Perl 5.005_03 instead of just 5.005, as some tests fail
7893 with 5.005_02.
7895 * doc/autoconf.texi (Special Shell Variables): Document some
7896 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
7898 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
7899 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
7900 eval $LINENO is not portable in practice.
7902 2001-10-24 Akim Demaille <akim@epita.fr>
7904 * lib/Autom4te/General.pm (backname): New.
7906 2001-10-24 Akim Demaille <akim@epita.fr>
7908 * m4/: Remove, merged into...
7909 * config/: here.
7911 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
7913 * doc/autoconf.texi (Shellology): Mention the problems with bash
7914 2.05's use of ANSI quoting in its `set' builtin.
7916 2001-10-22 Paul Eggert <eggert@twinsun.com>
7918 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
7919 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
7920 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
7921 POSIX decided to standardize on the int flavor of strerror_r.
7922 Always do char* test, as there's no reason not to.
7923 Assign to a char* var, to catch strerror_r that returns int*.
7925 * doc/autoconf.texi (Particular Functions):
7926 Document the above changes. Also, document the fact that
7927 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
7929 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
7931 2001-10-20 Akim Demaille <akim@epita.fr>
7933 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
7934 the executable was missing from the log.
7936 2001-10-20 Akim Demaille <akim@epita.fr>
7938 * lib/Autom4te/General.pm (&update_file): If destination is
7939 unchanged, remove the source.
7940 (&up_to_date_p): Don't be verbose, be debug.
7941 * bin/autoreconf.in: No longer support --m4dir.
7942 (&autoreconf): Display the full path of the configure.ac we are
7943 studying.
7944 Trace it only once.
7945 Be sure to honor --force with gettextize.
7946 Always run aclocal.
7947 * doc/autoconf.texi: Adjust.
7949 2001-10-20 Akim Demaille <akim@epita.fr>
7951 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
7952 Remove, dead.
7953 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
7954 `intl' is already present, as it refuses unless --force.
7955 (&parse_args): Use -I, --include instead of the old Autoconf
7956 options.
7957 ($localdir, $autoconf_dir): Remove.
7958 (@include): New.
7959 (&maybe_autoreconf): New, to preserve $_ for File::Find.
7961 2001-10-19 Jens Petersen <petersen@redhat.com>
7963 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
7964 * doc/autoconf.texi (Particular Programs): Likewise.
7966 2001-10-19 Akim Demaille <akim@epita.fr>
7968 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
7969 file in @configure_input@.
7970 Don't mention `automatically' in addition to `generated'.
7971 * tests/torture.at (#define header templates): Adjust.
7973 2001-10-19 Akim Demaille <akim@epita.fr>
7975 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
7976 comment, explain how to install automatic mode selection.
7977 From Russ Allbery.
7979 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
7981 * bin/autoreconf.in (autoreconf): Display the path to the
7982 configure.ac being studied.
7984 2001-10-18 Paul Eggert <eggert@twinsun.com>
7986 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
7987 long, to work around a bug in the HP C compiler version HP92453-01
7988 B.11.11.23709.GP.
7990 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
7991 (AS_BASENAME_EXPR): New macro.
7992 (AS_BASENAME_SED): Do not assume GNU sed semantics.
7993 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
7994 and fall back on 'sed' only if the other two fail. This makes
7995 AS_BASENAME act more like AS_DIRNAME.
7996 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
7997 contains white space.
7998 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
7999 Use AS_DIRNAME, since I think it's now DOS-friendly.
8000 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8001 Allow "dirname //FOO" to return either / or //, as POSIX allows
8002 either behavior.
8004 2001-10-10 Akim Demaille <akim@epita.fr>
8006 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
8007 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
8008 From Eric Sharkey.
8010 2001-10-10 Akim Demaille <akim@epita.fr>
8012 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
8013 m4_define, since...
8014 (_AS_ECHO_N): AS_REQUIREs it.
8016 2001-10-10 Akim Demaille <akim@epita.fr>
8018 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
8019 (AC_INCLUDES_DEFAULT): Move to...
8020 * lib/autoconf/headers.m4: here.
8021 * lib/autoconf/types.m4: Comment changes.
8022 * doc/autoconf.texi: Specify where the default includes are used

8267 * tests/fortran.at (GNU Fortran 77): there.
8268 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8269 AC_TRY_RUN is about compilation, not shell commands.
8270 (Test Programs): AC_TRY_RUN works as used to be advertised.
8272 2001-09-27 Akim Demaille <akim@epita.fr>
8274 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
8275 Raja R Harinath:
8276 Be sure to detect when $LINENO always returns the same value.

8278 enough.

8281 2001-09-25 Akim Demaille <akim@epita.fr>
8283 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

8312 Don't compute at_srcdir nor at_top_srcdir.
8314 * tests/tools.at: Hence use top_srcdir.

8397 2001-09-21 Akim Demaille <akim@epita.fr>

8445 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
8446 already have $file). Set output files to binary mode (helps avoid
8447 CR issues on DOSish systems).
8449 2001-09-19 Akim Demaille <akim@epita.fr>
8451 * lib/autotest/general.m4: Englishoes.
8452 From Tim Van Holder and Alexey Mahotkin.
8454 2001-09-18 Paul Eggert <eggert@twinsun.com>
8456 * doc/autoconf.texi (Common Shell Constructs): New node,

8464 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8465 Do not pass a first argument with leading '-'
8466 to expr, by parenthesizing initial integers that might be negative.
8468 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
8469 now merely checks whether it is an error to pass an argument
8470 to getpgrp.
8472 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
8473 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
8474 whether it is a (compile-time) error to pass an argument to
8475 getpgrp. This simpler test supports the revised documentation,
8476 and is all that AC_FUNC_GETPGRP's users really need.
8478 2001-09-18 Akim Demaille <akim@epita.fr>
8480 * doc/autoconf.texi (Limitations of Make) <$<>: New.

8491 correctly.
8492 Add test for AS_BASENAME.
8493 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
8494 added test. It now correctly handles /1/2/3/, returning '3' not ''.
8495 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
8496 * tests/base.at: Fixed the expected responses. The old ones were
8497 one line out...
8498 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
8499 the documentation claims it should (and how it behaved in 2.13).
8501 2001-09-18 Akim Demaille <akim@epita.fr>
8503 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
8504 the AC_CONFIG_COMMANDS invocation.
8505 This also solves the name clash problems.
8506 Don't set the package's ID.
8507 * lib/m4sugar/Makefile.am (version.m4): Revamp.
8508 No longer to be shipped.
8509 (version.in): Remove.
8510 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
8511 * lib/autoconf/status.m4: Adjust.
8512 Use `m4_PACKAGE_STRING'.
8513 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
8514 the only optional argument is the name of the test suite.
8515 Expect `package.m4' to define the package signature.
8516 * lib/autom4te.in (Autotest): Add `package.m4?'.
8517 * tests/Makefile.am (package.m4): New.
8518 * tests/suite.at: ifnames is a victim.
8520 2001-09-18 Akim Demaille <akim@epita.fr>
8522 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
8523 AC_LIBSOURCE, AC_CONFIG_FILES.
8524 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
8525 program version string doesn't match the package's.
8526 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
8527 after `(cached)'.
8529 2001-09-17 Paul Eggert <eggert@twinsun.com>
8531 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8532 Allow expression to return any value that can fit into unsigned long
8533 (not int, as before). Check for output errors.
8535 2001-09-17 Bruno Haible <haible@ilog.fr>
8537 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8538 Always include <stdio.h> and <stdlib.h>. Evaluate
8539 the expression in an extra function before these includes. Call
8540 fprintf "%d" only after ensuring the argument is of type 'int'.
8541 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
8543 2001-09-17 Paul Eggert <eggert@twinsun.com>
8545 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
8546 or CFLAGS=-O5. In that case, the linker has a relaxed view of
8547 fatal errors, and AC_CHECK_LIB causes it to include libraries even
8548 when they don't exist.
8550 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
8551 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
8552 need it.
8554 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
8555 version with the version used by fileutils 4.1, except use
8556 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
8557 we don't need it.
8559 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
8561 2001-09-13 Akim Demaille <akim@epita.fr>
8563 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
8564 _first_.
8565 Reported by Gerrit P. Haase.
8567 2001-09-13 Akim Demaille <akim@epita.fr>
8569 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

8588 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
8589 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
8590 AT_tests_all for consistency.
8591 Set at_victims.
8592 (AT_VICTIMS): Similar to AT_KEYWORDS.
8593 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
8595 2001-09-13 Akim Demaille <akim@epita.fr>
8597 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
8599 2001-09-13 Akim Demaille <akim@epita.fr>
8601 * lib/autotest/general.m4 (AT_INIT): Create and remove
8602 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
8603 test suites can cohabit.
8605 2001-09-13 Akim Demaille <akim@epita.fr>
8607 * tests/mktests.sh: Don't output banners for empty test files.
8609 2001-09-13 Akim Demaille <akim@epita.fr>

8655 Spread a few keywords in the Autoconf test suite.
8657 2001-09-10 Akim Demaille <akim@epita.fr>
8659 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
8660 PATH_SEPARATOR, let M4sh compute it.
8661 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.
8662 * lib/autoconf/programs.m4 (AC_SHELL_PATH_WALK): Use PATH_SEPARATOR.

8675 2001-09-07 Akim Demaille <akim@epita.fr>
8677 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
8678 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
8679 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
8680 related variables into `at_package_*'.
8681 * lib/autotest/general.m4 (AT_VICTIMS): New.

8690 Move toward possibly stand-alone test suites.
8692 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
8693 in addition, it introduces useless differences in logs.

8695 Adjust PATH computation.
8696 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

8706 to avoid GCC warnings.
8707 From Uwe Seimet.
8709 2001-09-05 Akim Demaille <akim@epita.fr>
8711 * bin/autom4te.in: --language is -l, not -s.
8713 2001-09-05 Akim Demaille <akim@epita.fr>
8715 Be ready to handle filenames as stupid as `dnl.at', for if even
8716 the maintainer is dumb enough to do that...
8718 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
8719 excellence in M4 quotation: consider `__file__' is active.
8721 And BTW, when invoking m4, pass the --include in the right order:
8722 the wrong one.
8724 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
8725 4m.
8727 2001-09-05 Akim Demaille <akim@epita.fr>
8729 * lib/Autom4te/XFile.pm: New lib file.
8730 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,

8743 * bin/autoscan.in: Use `getopt' and `find_files' etc.
8744 Add -I, --include support.
8745 * doc/autoconf.texi (autoscan Invocation): Adjust.
8747 2001-09-05 Akim Demaille <akim@epita.fr>
8749 CVS GNU M4 doesn't like `undefine(undefined)'.
8751 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
8752 New, extracted from main.
8753 Use IO::File wherever possible.
8754 (input.m4): Be constant, use -I instead of hard coding $tmp.
8755 Therefore be a quoted heredoc.
8756 Don't invoke `_au_disable', since ac was not loaded, but just
8757 `unm4.m4'.
8759 2001-08-31 Akim Demaille <akim@epita.fr>
8761 Version 2.52d.
8763 2001-08-31 Akim Demaille <akim@epita.fr>

8782 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
8784 2001-08-31 Akim Demaille <akim@epita.fr>
8786 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
8787 (testsuite Scripts): There is no such thing as `atconfig.in'.
8788 And actually one diagram is missing: test suite runtime.
8790 2001-08-31 Akim Demaille <akim@epita.fr>
8792 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
8793 inverse order.
8795 2001-08-31 Akim Demaille <akim@epita.fr>
8797 * bin/autoupdate.in (@include): `installcheck' revealed the path
8798 to m4sugar was lacking!
8800 2001-08-31 Akim Demaille <akim@epita.fr>
8802 * man/Makefile.am (.x.1): We really have to pass
8803 autom4te_perllibdir.
8805 2001-08-31 Akim Demaille <akim@epita.fr>
8807 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
8808 debug scripts, in particular passing explicitly listed tests to
8809 run is stupid.
8811 2001-08-31 Akim Demaille <akim@epita.fr>
8813 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
8814 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
8815 Use directly autom4te, not autoconf.
8816 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
8818 2001-08-31 Akim Demaille <akim@epita.fr>
8820 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
8821 * bin/autoheader.in (%symbol): Strip arguments of macros.

8827 2001-08-31 Akim Demaille <akim@epita.fr>
8829 * bin/autom4te.in (&parse_args): Die on unknown languages.
8830 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
8831 need for autoconf.
8832 Promote --include over --macrodir and other obsolete options.
8834 2001-08-31 Akim Demaille <akim@epita.fr>
8836 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

8838 * bin/autom4te.in ($autoconf): Pass --force.
8839 `print $out' doesn't print `$_' but `$out'.
8840 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
8841 (autoheader): Pass --force since the test suite goes too fast for
8842 the time stamps.
8843 Adjust to the new autoheader messages.
8845 2001-08-31 Akim Demaille <akim@epita.fr>
8847 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
8848 Check the completeness of the #template.

8856 * bin/autoupdate.in, bin/autoheader.in: Adjust.
8857 Drop AC_MACRODIR dead for real.
8858 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
8859 `autoheader: `config.hin' is created'.
8860 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
8862 2001-08-31 Akim Demaille <akim@epita.fr>
8864 * bin/autoheader.in: Rewrite in Perl.
8865 * tests/autoheader: Adjust.
8867 2001-08-31 Akim Demaille <akim@epita.fr>
8869 * bin/autoconf.in (--include, -I): New option.
8870 Map --localdir, --autoconf-dir onto it.
8871 Forward autom4te's options instead of interpreting them.
8872 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
8873 There is no such envvar since the inception of autom4te.cfg.
8874 * bin/autom4te.in (&parse_args): Uniquify `@include'.
8875 * bin/autoupdate.in: Adjust, and perform more control.
8876 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
8877 * tests/autoconf: Dittowise.
8879 2001-08-31 Akim Demaille <akim@epita.fr>

8882 * bin/autom4te.in (&find_file): Support `FILE?' standing for
8883 optionally `FILE'.
8884 Use -e, not -f, since /dev/null for instance is OK.
8885 (&parse_args): Adjust.
8886 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
8888 2001-08-31 Akim Demaille <akim@epita.fr>
8890 * configure.ac: Also find tested executables in bin.
8891 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
8892 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
8893 installed peer executables, only PATH is allowed to resolve it.
8894 Pass `autoconf_dir' via options, not via invisible envvars.
8895 * lib/Autom4te/General.pm (&find_peer): Remove.
8896 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
8897 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
8898 * man/Makefile.am: Let help2man rely on PATH instead of trying to
8899 find the executables for it.
8900 * tests/Makefile.am: Major cleanup. Too lazy to document...
8901 * tests/atlocal.in: Remove all the obscure envvar manipulations.
8902 We only need PERL.
8903 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
8904 indeed related to running the test suite, while passing
8905 --autoconf-dir and others is related to running non installed
8906 Autoconf executables. So don't do that, leave it to...
8907 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
8908 * tests/autoscan: New.
8909 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
8910 refer to library files: rely on --language.
8912 2001-08-29 Akim Demaille <akim@epita.fr>
8914 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
8915 s/--set/--language/.
8917 2001-08-29 Akim Demaille <akim@epita.fr>
8919 * doc/autoconf.texi: Strip the @nodes.
8920 Suggested by Paul Eggert.
8921 (Initializing configure): Typo.
8923 2001-08-29 Akim Demaille <akim@epita.fr>
8925 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
8926 Suggested by Paul Eggert.
8928 2001-08-29 Akim Demaille <akim@epita.fr>
8930 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
8931 download in a tmp dir.
8933 2001-08-29 Akim Demaille <akim@epita.fr>
8935 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
8936 case insensitive OSes out there :(
8937 From Tim Van Holder.
8939 2001-08-29 Akim Demaille <akim@epita.fr>
8941 * lib/autom4te.in: New.
8942 * lib/Makefile.am (edit, autom4te.cfg): New.
8943 * bin/autom4te.in (BEGIN): Simplify.

8947 * bin/autoconf.in: Simplify and adjust.
8948 * tests/Makefile.am (AUTOMAKE): Use --set.
8949 * tests/atlocal.in: Adjust.
8950 * BUGS: distcheck and check are weak.
8952 2001-08-29 Akim Demaille <akim@epita.fr>
8954 * lib/autotest/general.m4: Use
8955 foo=`(command) 2>/dev/null`
8956 not
8957 foo=`command` 2>/dev/null
8958 (at-devnull): Rename as...
8959 (AT-devnull): this.
8960 (--clean): Remove AT-* files too.

9468 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
9470 * tests/semantics.at (AC_C_BIGENDIAN): New test.
9472 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9474 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
9475 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
9476 * doc/autoconf.texi (C Compiler Characteristics): Update
9477 documentation for AC_C_BIGENDIAN.
9479 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9481 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
9482 magic values from an object file when cross-compiling.
9483 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
9485 2001-08-10 Akim Demaille <akim@epita.fr>
9487 * bin/autom4te.in (&handle_output): Don't use `grep' with side
9488 effects.
9489 Suggested by Russ Allbery.
9491 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
9493 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
9494 current $prefix to the sub-configures.
9496 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
9498 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
9499 extension (needed on BeOS). Reported by Guido van Rossum.
9501 2001-08-09 Akim Demaille <akim@epita.fr>
9503 * bin/autom4te.in ($icache): Load it only if older than autom4te.
9505 2001-08-07 Akim Demaille <akim@epita.fr>
9507 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
9508 removed.
9509 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
9510 No need to remove the files before and after the each test, before
9511 each test and at the end of the suite is enough.
9512 Display only the children `times', not the shell's.
9513 If the test failed or was skipped, at-times is not available.
9515 2001-08-07 Akim Demaille <akim@epita.fr>
9517 Always produce testsuite.log, including when there are no
9518 failures. This helps getting information on skipped tests, and
9519 duration of the tests. Err, implement the latter btw.
9521 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
9522 Dump information on the first run of each test.
9523 (AT_CLEANUP): Create `at-times' containing the duration of the
9524 test group.
9526 2001-08-07 Akim Demaille <akim@epita.fr>
9528 The use of `dumpstat' revealed that `len' was used although it
9529 should not. m4_text_wrap was using it, but in the Autoconf world
9530 where it is legal. Hence (i) test M4sh in its own world, not
9531 Autoconf's, and (ii), ahem, fix the bug :)
9533 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
9534 does not like `' instead of [].
9535 (AT_INIT): Forbid `^_?AT_'.
9536 And don't output such tokens.
9537 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
9538 `script.as', and `autom4te.cache'.
9539 Remove `empty' and `macro' which are no longer used.
9540 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
9541 * tests/m4sugar.at: Use it.
9542 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
9544 2001-08-07 Akim Demaille <akim@epita.fr>
9546 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
9548 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
9550 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
9552 2001-08-04 Akim Demaille <akim@epita.fr>
9554 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
9555 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
9556 AC_TRY_LINK.
9557 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
9558 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
9559 (AC_F77_MAIN): Likewise.
9561 2001-08-04 Akim Demaille <akim@epita.fr>
9563 Don't rely on M4sugar outputting the patterns in files, since we
9564 might process the output _without_ running m4, hence without these
9565 files.
9567 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
9568 * bin/autom4te.in (@Request::includes): Remove, unused.
9569 (@Request::source): Rename as...
9570 (@Request::input): this.
9571 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
9572 (&handle_output): Fetch the patterns from the traces.
9573 `$forbidden' and `$allowed' are constant: use m//o.
9574 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
9575 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
9577 2001-08-04 Akim Demaille <akim@epita.fr>
9579 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
9580 autoconf', i.e., in addition to caching traces, cache the output.
9582 * bin/autom4te.in (Request::cache): Rename as...
9583 (Request::id): this.
9584 ($cache, $icache, $tcache, $ocache): New.
9585 (&handle_m4): Save M4 output in the cache instead of $tmp.
9586 (&handle_output): Adjust.
9587 (&up_to_date_p): Check that the output cache is up to date too.
9588 (top level): Run `&handle_m4' iff force or the cache is invalid.
9589 Run `&handle_output' if the output cache is more recent.
9591 2001-08-04 Akim Demaille <akim@epita.fr>
9593 * bin/autom4te.in ($force): New.
9594 (&parse_args, &print_usage): -f, --force is a new option.
9595 (&handle_output): CPP directives might have spaces after `#'.
9596 (&parse_args): The first file only can be frozen.
9598 2001-08-04 Akim Demaille <akim@epita.fr>
9600 Don't let autom4te compute the `include' traces several times:
9601 first check that the trace cache file is up to date, and then
9602 compare its timestamp with that of the output.
9604 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
9605 the preamble. Don't require 5.005 as Autom4te::General does it,
9606 and better yet (use `use', not `require'!).
9607 * lib/Autom4te/Struct.pm: Rename the last occurrences of
9608 Class::Struct as Autom4te::Struct.
9609 * lib/Autom4te/General.pm (File::stat): Use it.
9610 (&mtime): New, export it.
9611 * bin/autom4te.in: Use it.
9612 Declare `$req' is invalid if it is outdated.
9613 Don't declare it valid before saving it if something went wrong.
9615 2001-08-04 Akim Demaille <akim@epita.fr>
9617 Autom4te shall not encode Autoconf data, and preselecting traces
9618 must be proposed to the users.
9620 * bin/autom4te.in (@required_trace): Remove.
9621 (@preselect): New.
9622 (&parse_args, &print_usage): -p, --preselect is a new option.
9623 (&up_to_date_p): Adjust.
9624 * bin/autoconf.in: Preselect some Autoconf macros.
9626 2001-08-04 Akim Demaille <akim@epita.fr>
9628 * tests/tools.at (autoconf --trace: user macros): Check traces on
9629 macros invoked without arguments, and macros invoked with multiple
9630 lines arguments.
9632 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
9634 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
9635 arguments.
9637 2001-08-03 Akim Demaille <akim@epita.fr>
9639 * bin/autoconf.in ($@): Work around the usual sh bug.
9640 From Nicolas Joly.
9642 2001-08-03 Akim Demaille <akim@epita.fr>
9644 Clean up the handling of the M4 builtins tracing exception.
9646 * bin/autom4te.in (Request::request): Don't complete M4 builtins
9647 trace requests.
9648 (@m4_builtins): Rename as...
9649 (@m4_builtin): this.
9650 (%m4_builtin_alternate_name): New.
9651 (&parse_args): Complete the trace requests with alternate names.
9652 (&handle_traces): Hence no longer do it here.
9653 (&trace_requests): Remove, unused.
9655 2001-08-03 Akim Demaille <akim@epita.fr>
9657 * doc/autoconf.texi (Redefined M4 Macros): Document m4_exit,
9658 m4_if, and m4_wrap.
9660 2001-08-03 Akim Demaille <akim@epita.fr>
9662 * lib/m4sugar/m4sugar.m4 (m4_init): Also forbid `_m4_*' tokens.
9663 (m4_divert_pop): Dump the whole diversion stack when a diversion
9664 mismatch happens.
9665 * bin/autom4te.in (&handle_output): Remember of the first
9666 occurrence of a possibly undefined macro, not the last.
9667 Complain about the possibly undefined macros in the same order as
9668 the appear in the output.
9669 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
9670 * tests/tools.at (autoconf: forbidden tokens, basic)
9671 (autoconf: forbidden tokens, exceptions): No longer sort
9672 autoconf's stderr, as it is now deterministic.
9673 Check that `dnl' is caught.
9675 2001-08-01 Akim Demaille <akim@epita.fr>
9677 * configure.ac: Bump to 2.52c.
9679 2001-08-01 Akim Demaille <akim@epita.fr>
9681 Version 2.52b.
9683 * lib/Autom4te/Makefile.am (perllibdir): s/Autoconf/Autom4te/.

9689 2001-08-01 Akim Demaille <akim@epita.fr>

9695 `END', as `Autom4te::General::END' will be triggered.

9697 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of

10132 cross-language link tests can be performed successfully.
10133 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
10134 after $LIBS, for consistency; this should be the general rule since
