1 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
3 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
4 ac_config_guess, ac_config_sub, and ac_configure, since evidently
5 some other programs unwisely rely on these undocumented vars.
6 But put in warning comments about them.
7 Problem reported by Ralf Wildenhues in
8 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
9 * NEWS: Document that these variables are intended to go away.
11 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
13 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
14 and set the language to C++ (analogous to the equivalent Fortran
15 tests).
17 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
18 * doc/autoconf.texi (C++ Compiler): Document it.
19 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
20 * NEWS: Update.
22 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
24 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
25 that caused config.status to generate 100-command sed scripts; the
26 portable limit is 99.
28 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
30 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
31 variable `ac_d' instead of `d' to avoid infringing namespace.
32 Report by Ralf Menzel.
34 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
36 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
37 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
38 * tests/tools.at (autoconf: subdirectories): New test, taken from
39 the corresponding problem report by Ralf Wildenhues in:
40 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
42 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
43 Quote some uses of shell variables if they might suffer unexpected
44 globbing. This doesn't fix all instances of quoting problems that
45 I found, just the easy ones that look safe.
46 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
47 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
48 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
49 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
50 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
51 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
52 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
53 Likewise.
54 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
55 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
57 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
59 * bin/autoreconf.in ($help): Reword according to the manual.
60 Suggested by Olly Betts.
62 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
63 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
65 * bin/autoreconf.in: Pass the directory argument to
66 `require_configure_ac'. Fix comment.
67 * tests/torture.at (Configuring subdirectories): Expose this.
68 Reported by Olly Betts.
70 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
72 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
73 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
74 Automake as follows:
76 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
77 `$configure_in' instead of `configure.in', to preserve
78 directory component.
80 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
82 * config/config.guess, config/config.sub, config/texinfo.tex,
83 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
85 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
87 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
88 test for C99 conformance; (bool) 0.5 is an integer constant
89 expression, but (bool) -0.5 is not. Problem reported by Fedor
90 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
92 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
94 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
95 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
96 Warn about obsolete install-sh files. Remove stray sentence
97 fragment and fix cross reference.
98 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
99 install -d; this undoes the 2006-05-10 change.
100 (MKDIR_P): Mark with AN_MAKEVAR.
101 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
102 that we don't require $INSTALL to be thread-safe. Move comments
103 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
104 of AC_PROG_INSTALL. Output a message saying that we're checking
105 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
106 MKDIR_P instead of AC_SUBST.
107 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
108 Special magic for MKDIR_P, too.
109 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
110 a dnl.
111 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
113 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
115 Sync from Automake, as follows:
117 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
118 * config/install-sh: Initialize IFS, so field splitting isn't
119 turned off later.
120 * config/mkinstalldirs: Likewise.
121 * config/missing: Remove superfluous quotes. Replace all uses of
122 `[' by `test', for consistency, and for..
123 * config/missing (sed_minuso, sed_output): New variables.
124 (autom4te, help2man, makeinfo): Use them. Unifies detection of
125 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
126 Fixes `missing' to detect `--output' for help2man. Fixes
127 PR automake/483. Report by Dennis J. Linse.
128 (autom4te): Document in `missing --help'.
130 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
132 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
133 * config/install-sh: Don't use 'path' to talk about file names,
134 as per GNU coding standards. Close a race condition reported by Ralf
135 Wildenhues and Stepan Kasal. There is still a race condition
136 on hosts that predate Posix 1003.1-1992, but we can't help this.
137 Don't mishandle weird characters like space on pre-Posix hosts.
138 Invoke mkdir at most once per dir arg on pre-Posix hosts.
139 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
140 AC_PROG_MKDIR_P from AS_MKDIR_P.
141 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
142 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
143 earlier editions are not (including Automake 1.8.3).
144 Do not suggest mkinstalldirs for thread-safety.
145 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
146 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
147 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
148 presence of special characters and race conditions.
149 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
150 in Autoconf's name space.
152 2006-05-10 Bruno Haible <bruno@clisp.org>
153 and Paul Eggert <eggert@cs.ucla.edu>
155 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
156 from Automake with minor changes.
157 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
159 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
161 * config/install-sh: Update to Automake CVS version, as follows:
162 2006-04-25 Stepan Kasal <kasal@ucw.cz>
163 * lib/install-sh: Simplify the expr implementation of dirname.
164 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
165 * lib/install-sh: Handle --, and diagnose unknown options.
167 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
169 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
170 `./autom4te' to create `./testsuite', since the `all' target
171 will ensure its presence, but `installcheck' should not create
172 the uninstalled wrappers.
174 * tests/torture.at (Unusual Automake input files): Skip if we
175 detect automake < 1.8.
177 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
179 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
180 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
181 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
182 * NEWS: Update.
184 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
186 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
187 munge (multiple) white space and other oddities.
188 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
189 single quotes in variable assignment.
190 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
191 and similar failures by adding multiple spaces, tabs, and other
192 special characters.
193 Report and different test suggested by Francesco Romani
194 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
196 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
197 single quotes, we only need to search for single quotes; this
198 both simplifies the search pattern, and makes us less
199 susceptible to `echo' variations for arguments not containing
200 single quotes.
201 (_AC_ARG_VAR_VALIDATE): Likewise.
203 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
205 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
206 `$*' and IFS concatenation issue with traditional shells and
207 bash-2.04. Report by Seanster@Seanster.com.
209 2006-05-03 Bruno Haible <bruno@clisp.org>
211 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
212 precisely which Mac OS X versions have the od problem.
214 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
216 * doc/autoconf.texi: Use @option systematically.
217 (Integer Overflow):
219 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
220 and Bruno Haible <bruno@clisp.org>
222 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
223 about 'od'.
224 (Integer Overflow): Mention the special case of integer division
225 overflow.
227 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
229 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
230 traditional shells like the Solaris one that do not use the
231 first IFS character for assembling `$*'.
232 Prompted by a related report from autoconf_bug@nro.ca.
234 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
235 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
237 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
238 Mention more problems with the -e option.
240 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
242 * NEWS: Typo.
243 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
245 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
246 in URLs to improve DVI formatted output (requires texinfo 4.6).
247 (System Services, Systemology, Shellology): Likewise.
248 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
249 output.
251 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
252 continuous text.
253 (Runtime): Fix macro argument names to match description:
254 `action-if-found' -> `action-if-true' and similarly.
255 (Obsolete Macros): Likewise.
256 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
257 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
258 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
260 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
262 * doc/autoconf.texi (Limitations of Make): Clean up markup.
264 * ChangeLog: Typo.
265 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
266 DVI output.
268 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

280 (Writing Test Programs): Fix some langauge. Recommend exiting
281 with status 1, not merely nonzero. Clarify exit declaration.
282 (Run Time): Move C exit status stuff to new Exiting Portably section.
283 (Systemology): Mention Posix and levenez. Update v7 reference.
284 (Portable Shell): Mention the Posix shell.
286 2006-04-25 Stepan Kasal <kasal@ucw.cz>
288 * bin/autoconf.as (me): Replace by as_me.
290 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
292 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
293 since as_me isn't set yet.
295 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
297 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
298 a few minor bugs in this area.
300 * doc/autoconf.texi (Programming in M4sh): Comment out the
301 documentation of AS_BASENAME, for now.
302 (Shell Substitutions): Do not use AS_DIRNAME in an example.
303 (Limitations of Builtins) <basename>: Do not refer to
304 AS_BASENAME.
305 * bin/autoconf.as (me): Don't use AS_BASENAME.
306 (dir): Remove the unused variable.
307 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from

314 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
315 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
316 (_AS_DIRNAME_PREPARE): Likewise.

318 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
319 (AS_DIRNAME): Use "dirname --".
321 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
323 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
324 of "run time" and "run-time" changed to "runtime", for consistency.

331 with more accuracy and detail.
333 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
335 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
336 Archive is not officially `GNU' any more. Update URL.
337 (Defining Directories): Likewise
338 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
340 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
342 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
343 newline from the `trap' code to finish `config.log'; the NetBSD
344 /bin/sh resets the exit status after an empty command, as
345 documented in doc/autoconf.texi.
346 Reported by Dalibor Topic <robilad@kaffe.org>.
348 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
350 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
351 Suggested by Bruno Haible.
353 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
355 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
356 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
357 Instead, just list the shells that we know work.
358 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
359 changed. Be more cautious about the _cv_ variable.
360 * tests/tools.at (Syntax of the shell scripts): Check the
361 _cv_ variable once, at first, to avoid an internal autoconf error
362 when sh -n does not work.
364 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
366 * lib/Autom4te/FileUtils.pm: Sync from Automake.
368 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
370 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
371 use ">&-" since we're only 99.999% sure that this is portable,
372 and since the MinGW bug is fixed in a different way.
373 * lib/autotest/general.m4 (AT_INIT): Likewise.
375 2006-04-16 Stepan Kasal <kasal@ucw.cz>
377 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
378 before opening config.log, to avoid hitting a bug on MinGW.
380 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
382 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
383 AS_MESSAGE_LOG_FD before reopening it onto the log file.
384 This works around a MinGW bug reported by Eric Paire.
385 Make sure that all writes to the log file append to it,
386 rather than possibly losing data.
387 * lib/autotest/general.m4 (AT_INIT): Likewise.
389 2006-04-14 Stepan Kasal <kasal@ucw.cz>
391 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
392 description.
394 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
396 * NEWS: Update.
398 * configure.ac (AC_INIT): Bump to 2.59d.
400 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
402 Version 2.59c.
404 * Makefile.maint (news-date-check): Do not require a leading `*'
405 before the release date in NEWS.
407 2006-04-12 Stepan Kasal <kasal@ucw.cz>
408 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
410 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
411 the instantiated file do not contain the string 'datarootdir'
412 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
413 @mandir@, replace the reference '${datarootdir}' by the value.
414 * tests/torture.at (datarootdir workaround): New test.
415 * NEWS: Advertise this temporary fixup.
416 Based on a patch by Bruno Haible, reported and analyzed by
417 Paul Eggert and Noah Misch.
419 2006-04-12 Eric Blake <ebb9@byu.net>
421 * tests/autotest.at (Debugging a failed test): Fix comment.
423 2006-04-12 Stepan Kasal <kasal@ucw.cz>
425 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
426 all the changes since 2006-04-07.
428 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
430 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
431 succeeded, but `ln -s file dir' failed, take care to remove the
432 leftover target before the next test, to prevent its spurious
433 failure; also make sure `ln file dir' works before selecting it.
434 Thanks to Keith Marshall for pointing this out.
435 * THANKS: Update.
437 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
438 assignments in `at_debug_args', so that we put them correctly
439 in the `run' script.
440 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
441 Reported by Eric Blake.
443 2006-04-11 Eric Blake <ebb9@byu.net>
445 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
446 top-level tests after micro-suite has been run. Used in...
447 (Debugging a successful test, Debugging script and environment),
448 (Debugging a failed test): ...these new tests. The first of these
449 is fixed by...
450 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
451 macro, split out from...
452 (AT_INIT): ...here, so that using -d also generates a run script.
453 Document that -d inhibits top-level logging.
454 * doc/autoconf.texi (testsuite Invocation): Document that -d only
455 inhibits top-level logging; debug scripts are created.
457 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
458 check.
459 * tests/autotest.at (Empty test, Empty check): New test to check it.
461 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
462 from gcc.
464 2006-04-10 Stepan Kasal <kasal@ucw.cz>
466 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
467 the files if a problem appears. Make the empty *.at files
468 read-only, too. Proposed by Ralf Wildenhues.
470 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
472 * config/Makefile.am: Add comment to force updated Makefile.in.
474 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
475 space only patch to this file, this patch causes the Makefile.in
476 files that include freeze.mk to be updated, and thus have a
477 newer time stamp again, which in turn makes a pristine CVS
478 checkout have correct time stamps.
480 * Makefile.maint (cvs-sv): New macro, to be used..
481 (config.guess-url_prefix, config.sub-url_prefix)
482 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
483 point to CVS text checkout of Gnulib files.
484 (copyright-check): Bump current year.
485 (announcement): Do not hard-wire `./announce-gen'.
486 (cvs-update): Propagate failures of `cvs' and `move-if-change'
487 correctly.
488 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
489 `chmod +x'.
490 (wget_files): Update config.guess, config.sub, texinfo.tex by
491 `wget-update', now that their URLs work again.
493 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
495 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
496 Problem noted by Paul D. Smith.
498 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
500 * doc/autoconf.texi: Remove unused words from word list.
501 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
502 .x-sc_trailing_space: New files.
504 * doc/standards.texi: Sync from gnulib.
506 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
507 `LIBOBJDIR' as experimental.
509 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
510 with a target directory; it's internally implemented as `cp'
511 anyway, but since Autoconf advertises the possibility to use
512 a target directory when LN_S is `ln -s', we need to find out.
513 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
514 analyzed by Keith Marshall <keith.marshall@total.com>.
516 * THANKS: Update.
518 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
520 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
521 confdefs.h as-is. In general, if it has backslash-newline or the
522 like, then it doesn't work either to sort or to remove empty
523 lines.
525 2006-04-09 Stepan Kasal <kasal@ucw.cz>
527 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
529 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
531 * lib/autom4te.in (Automake-preselections): Preselect
532 _AM_SUBST_NOTMAKE.
534 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
536 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
537 apostrophe within a single-quoted string, as this is the usual
538 tradition and is easier to read than '"'"'. Don't rely on the
539 shell treating "$/" like '$/'. Use a more-consistent indenting
540 style for the trap.
542 2006-04-09 Eric Blake <ebb9@byu.net>
544 * tests/autotest.at (Backquote command substitution),
545 (Multiline backquote command substitution): Remove mistaken
546 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
547 applied...
548 (Parenthetical command substitution, Multiline parenthetical
549 command substitution): here.
551 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>

569 (Generic Functions): Add AC_CHECK_FUNCS_ONCE. Refer to new
570 Gnulib section.
571 (Particular Headers): Add AC_HEADER_ASSERT. For stdbool.h,
572 suggest a #define rather than a typedef for _Bool, and mention
573 Gnulib rather than trying to substitute stdbool code.
574 (Generic Headers): Add AC_CHECK_HEADERS_ONCE.
575 (Generic Declarations): Add AC_CHECK_DECLS_ONCE.
576 (Particular Structures): Add AC_STRUCT_DIRENT_D_INO,

581 AC_TYPE_INTMAX_T, AC_TYPE_INTPTR_T, AC_TYPE_LONG_DOUBLE,
582 AC_TYPE_LONG_DOUBLE_WIDER, AC_TYPE_LONG_LONG_INT, AC_TYPE_UINT8_T,
583 AC_TYPE_UINT16_T, AC_TYPE_UINT32_T, AC_TYPE_UINT64_T,
584 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
585 (C Compiler): Move AC_C_LONG_DOUBLE to ...
586 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
587 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.
588 (Posix Variants): Add AC_USE_SYSTEM_EXTENSIONS.
589 (Coding Style). Don't mention m4_expand_once.

601 Catch a bug in an HP-UX C compiler.
602 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): New macro.

608 New macros.
610 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not
611 use /^foo|bar$/, it does not mean /^(foo|bar)$/.
613 2006-04-08 Stepan Kasal <kasal@ucw.cz>
615 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Fix the wording
616 of the warning introduced by the 2001-08-28 change.
618 2006-04-08 Stepan Kasal <kasal@ucw.cz>,
619 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
621 * lib/autoconf/general.m4 (AC_CACHE_SAVE): All `ac_cv_env_foo'
622 variables shall be overriden by the cache.
623 * tests/torture.at (AC_ARG_VAR): Test also with a first value
624 that contains braces.
626 2006-04-07 Stepan Kasal <kasal@ucw.cz>
628 Revert the patch from 2006-04-01 and only improve
629 _AS_DETECT_BETTER_SHELL:
631 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
632 skip nonexistent directories.
633 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
634 only shell candidates which exist.
635 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
636 * lib/autotest/general.m4 (AT_INIT): No need to give three
637 parameters to _AS_PATH_WALK.
639 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
640 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
642 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
643 distinguish m4sugar macros.
644 * tests/tools.at (autoupdating with aclocal and m4_include):
645 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
646 test case by Noah Misch <noah@cs.caltech.edu>.
648 2006-04-07 Stepan Kasal <kasal@ucw.cz>
650 Revert my change from 2006-03-17, in other words:
651 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
652 and DUALCASE=1.
653 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
654 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
655 it is set.
657 2006-04-07 Eric Blake <ebb9@byu.net>
659 * doc/autoconf.texi (Programming in M4sh): Document that
660 AS_MKDIR_P exits the script on failure.
661 * lib/autotest/general.m4: Remove redundant AS_ERROR.
663 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
665 * config/elisp-comp, config/install-sh, config/mdate-sh,
666 config/missing, config/mkinstalldirs: Sync from Automake.
668 * lib/Autom4te/FileUtils.pm, lib/Autom4te/Struct.pm: Sync
669 from Automake.
671 * doc/make-stds.texi: Sync from gnulib.
673 2006-04-06 Eric Blake <ebb9@byu.net>
675 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
676 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced

680 Eric Blake <ebb9@byu.net>,
681 Paul Eggert <eggert@cs.ucla.edu>,
682 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
684 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
685 whether `set' quotes correctly: redirect stderr of the tested
686 `set', and use a subshell, for Ultrix; use `sed' instead of
687 `grep' for zsh `set' which may write binary output; match only
688 at the beginning of a line, to avoid false positives.
689 In order to avoid false positives by unrelated variables with
690 multiline content, put the dump algorithm in a subshell and
691 unset all variables containing newlines (except some which are
692 special to the shell). Warn about cache variables that are
693 unset.
695 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
697 * config/config.guess, config/config.sub, config/texinfo.tex:
698 Sync from upstream.

703 `_AC_' or `__AC_'. Noted by Stepan Kasal.
704 Update exclusion lists for the test suite to this end:
705 (AC_ARG_VAR): Do test this now.
706 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
707 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
708 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
709 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
711 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
712 shell issue with double-quoted command substitutions of native
713 commands.
714 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
715 Marshall.
717 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when
718 no file matches the glob, discard the warning, set `nullglob'.

720 (sc_cast_of_x_alloc_return_value): Likewise.
721 (sc_cast_of_alloca_return_value, sc_error_exit_success)
722 (sc_prohibit_jm_in_m4, .re-list, sc_unmarked_diagnostics)
723 (m4-check): Likewise.
724 (sc_system_h_headers): Do not print rule on execution.
725 (sc_tight_scope): Do not fail for non-existing `src' directory.
726 (sc_changelog): Skip the Copyright footer.
727 * lib/autoconf/lang.m4: Remove trailing space.
729 * lib/autoconf/status.m4: More replacements to
730 <tab><space> where this makes sense.

735 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
737 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
738 ac_config_<foo>s again, sometimes normalized, sometimes not.
739 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
740 (AC_CONFIG_COMMANDS): Do not do so here.
741 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
742 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
743 2005-07-25 rewrite. Noticed by Noah Misch.
745 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
746 _AC_PRESERVE_HELP_ORDER, ...
747 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
749 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
750 inside m4_expand_once; it is redundant.
752 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
753 for --help from Cygnus `configure.'
755 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
757 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
758 on a patch proposed by Ralf Wildenhues.
760 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
762 * lib/autoconf/status.m4: Replace <space>''<tab> with

765 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
766 Noah Misch <noah@cs.caltech.edu>
768 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
769 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
770 * doc/autoconf.texi (Help Formatting): New node.
771 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
773 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
775 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
776 lib/autoconf/specific.m4, lib/autoconf/status.m4,
777 lib/autoconf/types.m4, lib/autotest/general.m4,
778 tests/mktests.sh, tests/torture.at: White space cleanup:
779 remove some SPACE before TAB, or add quoting ('' or @&t@).
781 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.
783 * doc/autoconf.texi (Shell Substitutions): Document `^' vs. `|'.
785 2006-04-05 Eric Blake <ebb9@byu.net>
787 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
788 empty test suite works.
789 * tests/autotest.at (Empty test suite): Remove xfail.
791 2006-04-05 Noah Misch <noah@cs.caltech.edu>

795 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
796 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
797 normalizing it, consistent it with previous releases.
798 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
800 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
802 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
803 Use simplified args that Eric Blake originally suggested.
805 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
807 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
808 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
809 Use 'comm' rather than N instances of grep; this also fixes a bug
810 whereby substrings were incorrectly matched, causing us to not
811 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
812 (exclude_list): Exclude empty macros.
813 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.
815 Use awk rather than grep -E or egrep, to avoid
816 portability problems with regular expressions containing newlines.

818 Switch from grep to awk syntax.
819 (ac_exclude_script): Renamed from ac_exclude_egrep.

825 a subdirectory subject to Cygnus `configure'.
826 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
828 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
829 report request when we have no AC_PACKAGE_BUGREPORT.
831 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
833 * THANKS: Update.
835 * tests/mktests.sh: Update copyright year in the header of the
836 generated files.
838 * lib/autoconf/c.m4 (AC_C_INLINE): Do not skip cleanup code.
839 (AC_C_RESTRICT): Likewise. Furthermore, add a function with a
840 typedef'ed restricted pointer, to catch a compiler bug on
841 HP-UX 11.x, and fix warnings so it passes with -Werror.
842 (_AC_PROG_CC_C99): Likewise.
843 Reported by Albert Chin <china@thewrittenword.com>.
844 * tests/mktests.sh: Do not skip AC_C_INLINE, AC_C_RESTRICT.

853 2006-04-03 Noah Misch <noah@cs.caltech.edu>
855 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
857 2006-04-03 Eric Blake <ebb9@byu.net>
859 * THANKS: Add myself.
861 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
863 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
864 to log, point to testsuite output tree.
866 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
868 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.
869 * doc/autoconf.texi (Function Portability): Mention that C++
870 has trouble with 'exit'.
871 (Guidelines): Test programs shouldn't use 'exit'.
872 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
873 Remove; all uses removed.
874 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):
875 Return from 'main' instead of calling 'exit'.
876 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_CLOSEDIR_VOID):

892 2006-04-01 Stepan Kasal <kasal@ucw.cz>
894 Clean up _AC_COMPILER_EXEEXT* macros.
896 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
897 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
898 ac_file to the name of the default output file and call
899 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
900 initial `rm' of the candidate files...
901 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
902 the same list in subsequent `rm' calls, and for the temporary
903 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
904 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
905 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
906 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
907 no longer needed) by libtool. Make it a cache check.
908 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
909 copied here by mistake.
910 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
911 _AC_COMPILER_EXEEXT.
912 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
913 _AC_COMPILER_OBJEXT directly.
914 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
916 2006-04-01 Stepan Kasal <kasal@ucw.cz>

1686 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
1687 by the function rather than ignoring it.
1688 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
1689 comparing its address. Intel's interprocedural optimization was
1690 outsmarting the old heuristic. Problem reported by

1708 Stepan Kasal <kasal@ucw.cz>
1710 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
1711 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
1712 make its content writable before removing it. Remove an errorneous
1713 comment from the end, where the logs of the failed tests are copied
1714 to the main log file.
1716 2005-09-27 Stepan Kasal <kasal@ucw.cz>

1723 problems if the testsuite were running too fast.
1725 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1727 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

1739 suggested by Ben Elliston. Handle weird characters correctly.
1741 2005-09-06 Stepan Kasal <kasal@ucw.cz>
1743 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
1744 calls, so that the final expansion of this macro is shorter.
1745 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
1746 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
1747 the cleanup there. Use AS_VAR_* macros, to be more general.
1748 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
1750 * lib/autoconf/general.m4: Use AS_IF where appropriate.
1752 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

1770 2005-08-26 Stepan Kasal <kasal@ucw.cz>
1772 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
1773 in the example. Reported by Bruno Haible.
1774 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
1775 "if $undefined_var;" succeeds with my shell.
1777 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
1778 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
1779 but change the m4_divert_text to m4_divert_once.

1794 Stepan Kasal <kasal@ucw.cz>

1797 first header appears, define AH_HEADER.
1798 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
1799 Update limitations about when to call AC_CONFIG_HEADERS.
1800 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
1801 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
1802 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
1803 ``Configuration Actions''; fix their index entries.
1805 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
1806 options correctly. Process N-M as M-N if M is smaller than N.
1807 Process ranges correctly so that N-N will run only N.
1808 Sort and uniquify the tests that will be run. If there is more
1809 than one test, reinsert the banners for the tests.

1815 before passing the macro name to AH_TEMPLATE.
1817 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
1818 now opens log after option processing; in particular, --version
1819 and --help do not touch config.log.

1836 Prepend to LIBS, not append, in examples.
1838 2005-08-16 Stepan Kasal <kasal@ucw.cz>
1840 When building in place, set srcdir="."; suggested by Tim Van Holder.
1842 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
1843 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
1844 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
1845 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

1857 2005-08-12 Stepan Kasal <kasal@ucw.cz>
1859 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
1860 add "2>&1"; gzip 1.2.4 prints help on stderr.
1862 2005-07-27 Stepan Kasal <kasal@ucw.cz>
1864 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
1865 was pushdef'ed twice while popped only once. Push it only once.
1866 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
1868 2005-07-26 Stepan Kasal <kasal@ucw.cz>
1870 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
1871 prefixed by mere "===", not "configure: === ".
1873 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
1875 * Makefile.maint: Update from Bison.
1877 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
1878 "<tab>" in comment, so that the point is understandable.
1880 2005-07-25 Stepan Kasal <kasal@ucw.cz>
1882 Rewrite substantial part of lib/autoconf/status.m4.
1883 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
1884 and CONFIG_COMMANDS are not processed in four separate loops.
1885 Instead, there is one main loop. This alows that the common code
1886 is expanded only once, thus config.status (and configure) is smaller.
1888 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
1889 the AC_LIST_FILES and cousins macros are no longer used.
1891 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
1892 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
1893 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
1894 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
1895 contain the initialization, nor the for loop, nor the associated
1896 commands; all these go to ...
1897 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
1898 _AC_OUTPUT_CONFIG_STATUS.
1899 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
1900 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
1901 (_AC_OUTPUT_FILE): The creation of the sed script ...
1902 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
1903 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
1904 _AC_OUTPUT_MAIN_LOOP.
1905 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
1906 _AC_CONFIG_COMMANDS): Use ...
1907 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
1908 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
1909 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
1910 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
1911 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
1912 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
1913 ... new macros.
1914 (_AC_CONFIG_UNIQUE): Update.
1915 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
1916 Replaced by this ...
1917 (_AC_LIST_TAGS): ... new common macro.
1918 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
1919 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
1920 (_AC_LIST_TAG_COMMANDS): ... new common macro.
1921 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
1922 this didn't belong to the `config commands' section.
1923 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
1924 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
1925 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
1926 to the `config commands' section either.
1927 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
1928 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
1930 ... and many changes to the comments nearby.
1932 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
1933 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
1934 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
1935 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
1936 (#define header templates): The comment at the top of the generated
1937 header now includes the name(s) of the source file(s).
1939 Several unrelated small changes:
1941 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
1942 parameter to AC_DIAGNOSE.
1943 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
1944 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
1945 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
1946 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
1947 with AU::AC_OUTPUT.
1948 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
1949 in AC_OUTPUT doesn't double-quote it either.
1950 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
1951 parameters.
1953 2005-07-10 Stepan Kasal <kasal@ucw.cz>
1955 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
1956 versions of Portland Group compiler produce single- and double-quoted
1957 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
1958 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
1960 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
1962 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
1963 This is a corrected version of yesterday's patch.
1965 2005-07-07 Stepan Kasal <kasal@ucw.cz>
1967 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
1968 path, too; insert a "===" to emphasize the line.
1970 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD): Rename
1971 ac_cv_build_alias to ac_build_alias.
1972 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
1974 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
1975 change eliminates it. Problem reported by Alexandre Duret-Lutz.
1976 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
1977 (AC_ARG_VAR): ... here.
1978 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
1979 target_alias.
1981 Keep a list of all precious variables and process them with one simple
1982 for loop, instead of expanding all commands, or, OTOH, complicated
1983 processing of output of "set".
1984 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
1985 variable names in new macro...
1986 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
1987 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
1988 a loop to assign all ac_env_* and ac_cv_env_* variables.
1989 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
1990 to INIT_PREPARE.
1991 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
1992 its value to shell variable ac_precious_vars and call
1993 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
1994 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
1995 _AC_ARG_VAR_VALIDATE.
1997 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)

2015 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
2016 They are generated by the Tru64 v5.1B shell.

2020 Fix my changes from 2005-07-01; reported by Noah Misch.
2021 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
2022 description, the macro now accepts only a single tag.

2028 at_top_builddir, for compatibility with older autotest.
2029 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
2030 is not set, use at_top_builddir, for compatibility with older
2031 versions of autoconf.
2033 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
2035 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
2036 Problem reported by Patrick Welche.
2038 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
2040 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
2041 sed substitution command, so that we allow | in program prefixes
2042 and program suffixes. (& is a problem anyway; we're not fixing
2043 that here.)
2044 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
2045 configure_input, top_builddir, srcdir, etc.
2046 * lib/autotest/general.m4 (AT_INIT): Likewise, for
2047 PATH_SEPARATOR in AUTOTEST_PATH.
2049 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
2051 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the

2057 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
2058 directories with weird names. Apparently some people like living

2080 document to output the default config_* lists to config.status.
2081 Don't recognize option --file, if the functionality is not there.
2082 Likewise for --header; moreover, recognize --he and --h as shortcuts
2083 for --help in that case.
2085 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
2086 matches the order of execution. No code changed.

2108 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
2109 (AC_SUBST): Call it.
2110 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
2111 the directory specific variables; but don't call it for configure_input.
2113 2005-06-28 Derek Price <derek@ximbiot.com>
2115 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
2116 addition.
2118 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
2120 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
2121 directory have inherent problems with special characters like spaces,
2122 due to limitations in Make syntax. Problem reported by Alexandre
2123 Duret-Lutz.
2124 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

2137 from Justace Clutter.
2138 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
2139 variable into diagnostic. Make the diagnostic an error, not a warning,
2140 because we really don't support spaces and suchlike in dir names.
2141 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
2142 Don't worry about backslashes in srcdir; it can't happen now.

2156 that '\|' is not allowed in BREs; recommend using newline separated
2157 list of patterns instead of multiple -e options.
2159 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
2161 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

2167 2005-06-21 Stepan Kasal <kasal@ucw.cz>
2169 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
2170 b, t, r, w commands require single space, while : cannot have any.
2171 (Special Shell Variables): Fix sed code this in the example.
2172 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
2173 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
2175 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
2176 expand to the empty list. Don't use two pairs of m4_changequote,
2177 it's not necessary.
2179 2005-06-20 Derek Price <derek@ximbiot.com>
2181 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
2183 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
2185 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
2186 * doc/autoconf.texi:
2187 Don't mention Solaris versions so much, if a
2188 problem is common to all extant versions of Solaris. Say "SunOS
2189 4" instead of "SunOS" for SunOS 4.
2190 (awk): Mention more of the limitations of traditional Awk.
2191 (cat): Don't talk about cat -v.
2193 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>
2195 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE): New macro.
2196 (AS_VERSION_COMPARE): New macro. The API is taken from CVS,

2198 to be compatible with glibc strverscmp.
2199 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
2201 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
2202 on Mac OS X 10.4 reported by Peter O'Gorman in:

2204 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
2205 Use shell builtins rather than 'expr', to work around expr bug.
2207 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
2209 * doc/autoconf.texi: "filesystem" -> "file system".
2210 "behaviour" -> "behavior".
2211 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).

2218 * man/Makefile.am (MOSTLYCLEANFILES): Add $(srcdir)/*.t.
2219 (.x.1): Ignore the time stamp in the .TH line when deciding whether
2220 to update the man page. That way, we don't have to check in new
2221 man pages every month.
2223 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
2224 quotes and backslashes. Patch from Derek Price.

2228 * doc/autoconf.texi (Programming in M4sh): Document AS_TR_CPP &
2229 AS_TR_SH.
2231 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
2233 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
2234 -u, since it outputs chatter if the input files are the same.
2235 Problem reported by Ralf Menzel.
2237 2005-06-08 Derek Price <derek@ximbiot.com>
2239 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
2240 renaming them since they are about to be redefined anyhow.
2242 2005-06-08 Derek Price <derek@ximbiot.com>
2244 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
2245 redefined M4 macros to this node. Document m4_include & m4_sinclude.
2246 Move m4_undefine to alphabetical order.
2248 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
2250 * README: Recommend GNU M4 1.4.3 or later.
2251 * doc/autoconf.texi (Introduction): Likewise.
2252 Reword to avoid some formatting glitches.
2253 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
2254 Clarify explanation of HP compiler bug.
2255 Redo example output tp match current CVS snapshot.
2256 Use @example.org in email addresses when the examples
2257 might get inadvertently cut-and-pasted into user code.
2258 Remove example of autom4te usage that doesn't seem to work now.
2259 Use modern AC_INIT (except when the example is meant to be
2260 shown with Autoconf 2.13).
2261 Update ksh info for Solaris 9 and later.
2262 KB -> kB.
2263 Modernize description of Automake versions a bit.
2264 Don't claim a future version of Autoconf is near.
2265 * doc/install.texi: Reword to avoid some formatting glitches.
2267 2005-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2270 follows its own advice about quoting better.
2271 Reword to avoid some formatting glitches.
2272 * doc/installt.exi: Reword to avoid some formatting glitches.
2274 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
2275 Tru64 ksh pattern matching bug. Reported against Libtool by
2276 Albert Chin <libtool@mlists.thewrittenword.com> and
2277 Nicolas Joly <njoly@pasteur.fr>.
2279 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2281 m4_cdr of one-member list was [[]] (one-member list containing an
2282 empty string) instead of [] (an empty list. Callers were skewed to
2283 match this misbehaviour. As a consequence of this:
2284 - m4_foreach([x], [], [foo]) expanded to `foo', while
2285 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
2286 This bug has been fixed:
2288 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
2289 expand to an empty string; print error msg if called without
2290 an argument list.
2291 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
2292 misbehaviour; handle [] and [[]] correctly.
2294 2005-06-06 Stepan Kasal <kasal@ucw.cz>
2296 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
2297 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
2298 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
2300 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
2302 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
2303 swallow records with more than 99 fields.
2304 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
2305 parse the long line.
2307 2005-06-04 Stepan Kasal <kasal@ucw.cz>
2309 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
2310 swallow literals longer than 399. Reported by Ralf Wildenhues.
2311 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
2312 to workaround this limitation.
2314 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
2316 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
2317 to gfortran, and make these the first two compiler names
2318 checked (following the general autoconf preference for gcc).
2320 2005-06-03 Stepan Kasal <kasal@ucw.cz>
2322 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
2323 (DISTCLEANFILES): Remove $(check_SCRIPTS).
2324 (testsuite): Make sure autotest.m4f is up-to-date before using it.
2326 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
2328 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
2329 expression of unbounded size when processing the --list
2330 option. This runs afoul of a limit of 399 bytes per regular
2331 expression on AIX. Problem reported by Ralf Wildenhues.
2333 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
2335 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
2336 * doc/autoconf.texi (Particular Headers): Reword example
2337 for multiline stdbool replacement.
2338 (Setting Output Variables): Reword text a bit. Don't
2339 give all the details about |#_!!_#|.
2340 Reword description of line replacement.
2342 2005-05-31 Dan Manthey <dan_manthey@partech.com>
2344 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
2345 now contain newlines, and substituted files must be referenced on
2346 a line alone; the sed scripts to substitute them are now very
2347 different.
2348 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
2349 commands can be put in a sed script portably.
2350 * doc/autoconf.texi (Setting Output Variables): Document above
2351 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
2352 use of multiline substitution.
2353 * tests/torture.at: No longer expect substitution of newline to fail.
2355 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
2357 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
2358 From Ralf Menzel (trivial change).
2360 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
2362 * tests/local.at: Don't attempt to check for negated character
2363 classes in shell scripts. The test was too brittle.
2365 2005-05-25 Stepan Kasal <kasal@ucw.cz>
2367 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
2368 * doc/autoconf.texi (Limitations of Builtins): Document this
2369 limitation.
2371 2005-05-24 Stepan Kasal <kasal@ucw.cz>
2373 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
2374 common code; used in many places in the tree.
2375 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
2376 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
2378 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
2380 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
2381 messages when ac_unique_file is not found.
2382 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
2383 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
2384 commands, for consistency with AC_MSG_ERROR and such.
2386 * bin/autoconf.as: Make more use of "shift 2" in option processing.
2388 * bin/Makefile.am: Merge the two rules for creating scripts.
2390 2005-05-23 Stepan Kasal <kasal@ucw.cz>
2392 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
2393 obsolete; it was never documented.
2394 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
2396 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2398 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
2399 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
2400 (ac_top_builddir): ... this ...
2401 (ac_top_build_prefix): ... to this; the old name is also kept, for
2402 backward compatibility.
2403 (ac_top_builddir_sub): New variable, without the trailing slash,
2404 always nonempty.
2405 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
2406 * doc/autoconf.texi (Configuration Actions): Rename
2407 ac_top_builddir to ac_top_build_prefix.
2408 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
2409 at_top_builddir to at_top_build_prefix.
2410 * lib/autotest/general.m4 (AT_INIT): Likewise.
2412 2005-05-20 Stepan Kasal <kasal@ucw.cz>
2414 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
2415 of confdefs.h .
2417 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2419 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
2420 argument to m4_foreach. I guess it was necessary in the past,
2421 but I think it's a no-op now.
2423 2005-05-17 Stepan Kasal <kasal@ucw.cz>
2425 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
2426 ``cat <<_ACEOF'' commands to one.
2427 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
2428 * lib/autoconf/status.m4: On various places, use expr instead of
2429 ``echo|sed.''
2430 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
2431 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
2432 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
2433 a range.
2434 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
2435 the wrong patterns between ``case'' and ``esac.'' The previous
2436 code had false positives.
2438 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
2440 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
2441 as on 2005-05-02.
2442 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
2443 Mention LIBOBJDIR.

2483 2005-05-13 Stepan Kasal <kasal@ucw.cz>
2485 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
2486 check.
2487 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
2488 enough arguments, similarly as in m4_bpatsubsts.
2490 2005-05-12 Stepan Kasal <kasal@ucw.cz>
2492 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
2493 of absolute paths.
2495 2005-05-11 Stepan Kasal <kasal@ucw.cz>
2497 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
2498 for absolute directory names in one loop.
2499 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
2500 abbreviations of --version and --debug.
2502 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
2504 * doc/autoconf.texi (Autoconf Language): Be more precise about
2505 quoting rules. Problems noted by Stepan Kasal.
2506 Also, throughout this document, be more careful about white space.
2507 "blank", "white space", and "space" all have different meanings
2508 and we should be careful to say what we mean.
2510 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
2512 Fix C++ related problems reported by Werner Lemberg.
2513 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
2514 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
2515 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
2516 avoid problems with C++ and throw.
2517 * tests/compile.at: .cpp, not .cc.
2519 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
2521 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2523 * doc/autoconf.texi (Generic Functions): Typos.
2525 2005-05-02 Gary V. Vaughan <gary@gnu.org>
2527 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
2528 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
2529 set by latest automake.
2531 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
2533 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
2534 outputs 0 on GNU/Linux these days.
2536 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
2538 * doc/autoconf.texi (Autoconf Language): Add more description
2539 about quoting heuristics.
2540 (Limitations of Builtins): Describe "set -" problems.
2542 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2544 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
2545 not newline.
2547 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
2548 by AC_DEFINE; it was a mistake.
2549 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
2551 2005-04-25 Stepan Kasal <kasal@ucw.cz>
2553 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
2555 2005-04-22 Stepan Kasal <kasal@ucw.cz>
2557 * doc/autoconf.texi (External Software): Quadrigraphs are not
2558 processed correctly in AS_HELP_STRING; avoid this in the examples.
2559 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
2560 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
2561 comment and reduce m4_default([foo], []) to [foo].
2562 (m4_strip): Update the explanation.
2564 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
2566 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
2567 Remove core.conftest.* too; it's generated by Tru64 5.1.
2568 Problem reported by Jennis Pruett.
2569 * lib/autoconf/functions.m4
2570 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
2571 Don't bother to remove core files; AC_RUN_IFELSE should do that
2572 for you.
2574 2005-04-19 Stepan Kasal <kasal@ucw.cz>
2576 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
2578 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
2580 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.

2583 2005-04-15 Stepan Kasal <kasal@ucw.cz>
2585 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
2586 the comment.
2588 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
2590 * doc/autoconf.texi (External Software, Package Options): Add
2591 examples showing how to implement --with-* and --enable-* options.
2593 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
2595 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
2596 as well as configure.in. Problem reported by Gregorio Guidi.
2598 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
2600 * doc/autoconf.texi (Particular Functions): Use gnulib's current
2601 pattern for alloca snippet.

2611 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
2613 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
2614 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
2616 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2618 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
2619 Merge `-z option' as well for the benefit of Solaris link flags. Pass
2620 whole-archive (-zallextract, -zdefaultextract) options in the hope of
2621 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
2622 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
2624 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
2626 * NEWS: The configure command now warns you if you attempt to use
2627 a directory whose name contains a special character like space,
2628 newline, or "\".
2629 * doc/autoconf.texi (Installation Directory Variables): Allow
2630 "," in file names. Do not use \@; it's not a portable regexp.
2631 * bin/Makefile.am (edit): Likewise.
2632 * lib/Makefile.am (edit): Likewise.
2633 * tests/Makefile.am (edit): Likewise.
2634 * tests/semantics.at: Likewise.
2635 * tests/torture.at: Likewise.
2636 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
2637 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
2638 * doc/autoconf.texi (File System Conventions): Warn about
2639 unportable file names.
2640 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
2641 (AC_INIT): Use it.
2642 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
2643 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
2644 ac_pwd, and quote srcdir.
2645 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
2647 * doc/autoconf.texi: Fix some systematic formatting problems.
2648 ".)" needs a following @: if not at the end of a sentence, and
2649 similarly for "!)". "etc." should be preceded by a comma.
2650 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
2652 2005-03-22 Bruno Haible <bruno@clisp.org>
2654 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
2655 argument is often called 'build-aux'.
2657 2005-03-07 Stepan Kasal <kasal@ucw.cz>
2659 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
2660 macro AC_TRY_LINK is obsolete.
2661 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
2662 `AC_CONFIG_FILES'.
2664 2005-02-24 Stepan Kasal <kasal@ucw.cz>
2666 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
2667 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
2668 from a Common Lisp's `cl'.
2669 (AC_PROG_CXX): Behave according to the documentation: don't
2670 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
2671 make the variable CCC precious; use `cl.exe', not `cl'.
2673 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2674 Alexandre Duret-Lutz <adl@gnu.org>
2676 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
2677 /dev/null, as "configure" shouldn't read stdin, and this insulates
2678 us from problems (e.g., when testing for "cl"). Also, do this
2679 redirection before invoking "hostname" or "uname", and keep the
2680 original input stream available via...
2681 (AS_ORIGINAL_STDIN_FD): ... this new macro.
2682 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
2683 bother with "</dev/null" since it's now done at the top of
2684 'configure'.
2685 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
2686 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2687 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2688 * doc/autoconf.texi (File Descriptor Macros): New section.
2689 (Printing Messages): Mention it.
2690 * tests/base.at (Input/Output): New test.
2692 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
2694 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
2695 newline if neither \c nor -n work, as that would output two
2696 newlines. Prefer -n to \c. Reported by Stepan Kasal.
2698 2005-02-12 Stepan Kasal <kasal@ucw.cz>
2700 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
2701 This causes that any required macros inside will get before the if.
2702 * doc/autoconf.texi (autom4te.cache): A typo.
2704 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
2706 Undo previous change, except keep the change to
2707 lib/autoconf/programs.m4 that replaced grep with shell
2708 pattern-matching. This is because net-snmp configure reads stdin.
2709 Reported by Noah Misch.
2711 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
2713 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
2714 from /dev/null, as "configure" shouldn't read stdin, and this
2715 insulates us from problems (e.g., when testing for "cl").
2716 Suggested by Alexandre Duret-Lutz. Also, do this redirection
2717 before invoking "hostname" or "uname".
2718 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2719 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
2720 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
2721 "</dev/null" since it's now done at the top of 'configure'.
2722 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2723 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
2724 Also, replace grep with shell pattern-matching, to save a process.
2726 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
2728 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
2729 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
2730 avoid thinking that Allegro Common Lisp's "cl" command is a C++
2731 compiler.
2733 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
2735 * doc/autoconf.texi (Limitations of Usual Tools): Document that
2736 grep -q isn't portable. Improve grep -s explanation.
2737 Problem reported by Dan Manthey.

2793 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
2794 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name

2829 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
2831 Try not to generated lines of unlimited length, as POSIX places a
2832 2047-byte limit on line length of portable text files.
2833 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
2834 Use newline as a separator, not space.

2837 space.

2847 * doc/autoconf.texi (Special Shell Variables): Mention _,
2848 BIN_SH, DUALCASE. Say that variables other than "status" are safe

2853 with --help or --version.
2854 * lib/autoconf/general.m4 (_AC_INIT_HELP, _AC_INIT_VERSION): Likewise.

2892 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
2893 Update the long comment explaining it.
2895 m4_require no longer writes an ``is required by'' line to the
2896 execution stack. It contains only one bit of non-redundant
2897 information: that the macro was required, not called. And even
2898 this bit is useless in most situations: have you ever met a macro
2899 which both calls and requires the same macro?
2901 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
2902 (_m4_defun_pro_outer): ... only via this macro, for the outermost

2910 * tests/m4sugar.at (m4_require): Expect output without the
2911 ``is required by'' messages.
2913 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
2915 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
2916 rather than x for expr.
2918 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
2919 this is safe.
2920 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.
2921 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.

2933 from masters, so that FileUtils.pm's update_file provide --force
2934 support.
2935 * bin/autoheader.in: Pass $force to update_file so that
2936 config.h.in is always recreated when --force.

2942 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
2944 * doc/autoconf.texi (Limitations of Builtins): Clarify that
2945 "if test ! -d foo; ..." is portable. Suggested by Stepan Kasal.
2947 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
2949 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
2950 Warn about newline stripping in `` and $(). Update Solaris
2951 version to 9.
2952 (Limitations of Builtins): Use expr "X...", not expr "x...", as
2953 X insulates us from future changes to Posix.
2954 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
2955 stripping.
2957 2005-01-19 Stepan Kasal <kasal@ucw.cz>

2975 ulongval to be static, to avoid unwanted GCC warning. Problem
2976 reported by Michael Jennings via Daniel Reed; see
2977 <https://bugzilla.redhat.com/beta/show_bug.cgi?id=143852>.
2979 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
2981 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

2986 new variables.
2988 2005-01-04 Noah Misch <noah@cs.caltech.edu>
2990 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): If the Make program does
2991 not seem to work, assume it does set $(MAKE).

3003 (_m4_divert_n_stack): New macro; the expansion is
3004 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
3005 otherwise.
3006 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
3007 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
3008 stored in _m4_divert_diversion or _m4_divert_dump.
3009 (m4_divert_pop): When the parameter is given, compare the symbolic
3010 name with the last diversion pushed on the stack. Previously, the
3011 current diversion was compared with the numeric value of the
3012 diversion given as the parameter.
3013 (m4_require): If the macro hasn't been expanded yet, call ...
3014 (_m4_require_call): this new macro.

3047 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

3228 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
3229 Don't depend on .x file explicitly, since "make" does that for us.
3230 Suggested by Stepan Kasal.
3232 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
3233 Add *.tmp.

3293 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
3295 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
3296 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
3297 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
3298 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
3300 2004-12-07 Stepan Kasal <kasal@ucw.cz>
3302 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

3317 with exactly one parameter.
3319 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
3321 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
3322 "char c = '\200';" rather than "char c = 0x80;" as the
3323 latter doesn't conform to the strict C standard due to
3324 overflow on signed char hosts.
3326 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
3327 to -qlanglvl=ansi. We don't want to disable extensions.

3386 2004-11-13 Stepan Kasal <kasal@ucw.cz>
3388 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
3389 the $1_found variable, don't test whether the file is executable;
3390 Both things are checked ...
3391 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
3392 the former ``test -f''.
3393 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
3395 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

3402 * doc/autoconf.texi (Limitations of Usual Tools): Note `cp -r'
3403 limitations. Reorder paragraphs for clarity.
3405 2004-10-11 Paul Eggert <eggert@cs.ucla.edu>
3407 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed

3428 Problem reported by Stepan Kasal.
3430 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
3432 Fix problems reported by Andreas Buening in:
3433 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html

3439 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
3441 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
3442 "/usr/include", clear ac_x_includes instead of leaving it as "no"
3443 (trivial change). Problem and patch reported by Andrew Church in:
3444 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
3446 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

3473 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
3474 texinfo.tex for now (done by hand now).
3475 * Makefile.maint (wget_files, cvs_files):
3476 Remove ansi2knr.c; nobody uses it.
3477 (ansi2knr.c-url_prefix): Remove.
3478 (cvs-update): Fix test for failure. I don't know why it ever
3479 worked...
3481 * doc/autoconf.texi: Update URLs, some of which went stale.
3482 Use @uref rather than @href.
3484 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
3485 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
3487 * config/config.guess, config/config.sub, config/elisp-comp,
3488 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
3489 doc/fdl.texi, doc/standards.texi: Sync with master copy.
3491 * NEWS, TODO, configure.ac, bin/autoscan.in,
3492 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
3493 doc/install.texi, lib/Autom4te/Configure_ac.pm,

3497 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
3498 tests/tools.at, tests/torture.at:
3499 Use "file name" rather than "filename" or "path",
3500 to be consistent with the terminology of the GNU coding standards.
3502 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
3504 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
3505 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
3506 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
3507 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
3509 More fixes to support spaces in the name of the build directory.
3510 This isn't a complete fix but it's an improvement.
3512 * bin/autoconf.as (autom4te_options): New var.
3513 Use it instead of appending to AUTOM4TE, so that we can allow
3514 spaces in the build directory's absolute name.
3515 * bin/autoheader.in ($autoconf): Allow spaces in file names.
3516 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

3524 From Ralf Corsepius in:
3525 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
3527 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
3529 * doc/autoconf.texi (Function Portability): Document isinf and
3530 and isnan. From a suggestion by Kevin Ryde.
3532 * lib/Autom4te/General.pm (END): Return correct exit status even
3533 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
3535 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
3537 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
3538 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
3539 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
3541 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
3543 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
3544 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
3545 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
3546 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
3547 * lib/autom4te.in (Automake-preselections): Preselect
3548 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
3550 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
3552 * lib/autom4te.in (Automake-preselections): Preselect
3553 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
3554 trace them.
3556 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
3558 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
3559 Tru64.
3560 * doc/autoconf.texi (Shellology): Mention BIN_SH.
3561 Document problem with "`""`" in pdksh POSIX mode.
3563 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
3565 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
3566 with pdksh, too. Problem reported by Patrick Welche via
3567 Gary V. Vaughan.
3568 * doc/autoconf.texi (Shellology): Note that set -o posix is
3569 useful for pkdsh, too.
3571 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
3573 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
3574 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
3575 Don't fail if ENV or BASH_ENV is readonly.
3576 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
3577 etc. are read only. Problem reported by Ludovic Courtes.
3579 2004-06-23 Noah Misch <noah@cs.caltech.edu>
3581 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is

3583 (trivial change)
3585 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
3587 * doc/autoconf.texi (File System Conventions): Warn about
3588 names like "aux". Problem reported by Eric Blake.
3590 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
3591 by zero instead of array size, so that we can use any arithmetic
3592 constant expression (instead of requiring an integer constant
3593 expression). This allows us to test expressions like DBL_MAX <
3594 LDBL_MAX, which didn't conform to the C standard using the old
3595 method.
3596 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
3597 now that we can do floating-point tests at compile time.
3599 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
3601 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
3602 and LDBL_EPSILON, as the resulting expression isn't an
3603 integer constant expression and violates the C standard.
3604 Problem reported by Nelson H. F. Beebe. Also, check
3605 for "L" suffix, and check that long double doesn't have
3606 worse range or precision than double, that mixed-mode
3607 arithmetic doesn't generate a diagnostic, that double
3608 constants fit in long double.
3610 2004-06-03 Kevin Ryde <user42@zip.com.au>
3612 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
3613 malloc(0) and realloc(NULL,size).
3615 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
3616 Bob Proulx.
3618 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
3620 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
3621 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
3622 by Jim Meyering.
3624 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
3626 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
3627 can be rewritten using if-then-else. Suggested by Bruno Haible.
3629 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
3631 * doc/autoconf.texi (testsuite Scripts): Fix typo.
3632 Problem reported by Stepan Kasal.
3634 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
3636 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
3637 change). Patch reported by Ralf Wildenhues in
3638 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
3640 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
3641 function F exists if the compiler and linker let you compile an
3642 expression like (F != 0). Recent versions of GCC optimize away
3643 the reference to F in that case, since every function address must
3644 be nonzero, so the link succeeds even if F does not exist.
3645 Problem reported by Manu in
3646 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
3648 * doc/autoconf.texi (Systemology): Standardize on the spelling of
3649 "Unix". Many uses changed.
3650 (Limitations of Builtins): Explain better why the ! command isn't
3651 portable.
3653 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
3655 * lib/autom4te.in (Automake-preselections): Preselect
3656 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
3658 2004-05-19 Kevin Ryde <user42@zip.com.au>
3660 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
3661 referencing AC_FUNC_STRERROR_R.
3663 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
3664 note pessimistic assumption when cross compiling.
3666 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
3668 * doc/autoconf.texi (Limitations of Make): Note that BSD make
3669 (until 2004) invoked subcommands with sh -e, contra POSIX.
3670 Reported by Kevin Ryde.
3672 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
3674 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
3675 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
3676 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
3677 `test -f " /usr/bin/grep"', which _always_ failed.
3678 (AC_PROG_SED): Ditto bogus PATH fix.
3679 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
3680 requires that grep correctly supports _multiple_ `-e' options, rather
3681 than stating only that grep should accept `-e'.
3683 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
3685 Port to C99, which requires that 'exit' be declared.
3687 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
3688 to ensure that stdlib.h is included.
3689 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
3690 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
3691 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
3692 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
3693 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
3694 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
3695 when using 'exit' in a test; C99 requires that 'exit' be declared.
3697 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
3699 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
3700 now prefers 'grep' implementations that accept -e.
3701 (Limitations of Usual Tools): Describe problems of traditional
3702 egrep and fgrep with long input lines, and of traditional grep
3703 with -e.
3704 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
3705 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
3706 All callers changed. Append /usr/xpg4/bin to the PATH, for
3707 Solaris.
3708 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
3709 the user with complaints about multiple -e options.
3710 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
3711 Define it with AC_PROG_GREP.
3712 * configure.ac (AC_PROG_GREP): Add.
3713 * lib/freeze.mk (GREP): New macro.
3715 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
3717 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
3718 a possible candidate only after all others fail, rather than
3719 consulting it first. This improves backward compatibility by
3720 better reflecting the way shell selection occurred in previous
3721 versions of Autoconf, and should help to avoid triggering latent
3722 problems in other packages, such as the one in Automake where zsh
3723 is not handled robustly:
3724 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
3725 Although it is not Autoconf's responsibility to work around
3726 problems in Automake, it nevertheless makes sense to avoid
3727 introducing unnecessary incompatibilites.
3729 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
3730 Gary V. Vaughan <gary@gnu.org>
3732 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
3733 how deeply nested we are when a suitable tool is found, set the
3734 ac_path_TOOL_found flag.
3735 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
3736 nested we are in this macro. Break out of all 3 nested loops if
3737 ac_path_TOOL_found is set.
3739 2004-04-21 Gary V. Vaughan <gary@gnu.org>
3741 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
3742 of the _AS_PATH_WALK loop too if GNU flavor is found.
3744 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
3746 * doc/autoconf.texi (Limitations of Make): Update documentation
3747 for `$<'. New entry `Long lines', based on a report from Simon
3748 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
3749 paragraph about DJGPP, based on a mail from Richard Dawe.
3751 2004-04-20 Paul Eggert <eggert@twinsun.com>
3753 * tests/c.at (C keywords): Don't assume that GCC supports
3754 "restrict" and "inline", as sufficiently-old GCC versions do not
3755 (also, GCC configured to be in pedantic C89 mode does not).
3756 Problem reported by Sumit Pandya in:
3757 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
3759 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
3760 consider -g to work if it generates warnings when plain compiles
3761 don't. Problem reported by Braden McDaniel in:
3762 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
3764 * doc/autoconf.texi (Slashes): New section, to document a problem
3765 reported by Jim Meyering in:
3766 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
3768 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
3769 linker output files before linking, to work around IRIX 6 linker bug.
3770 Problem reported by Rainer Orth in:
3771 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
3773 2004-04-20 Gary V. Vaughan <gary@gnu.org>
3775 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
3776 best tool so far counter rely on the tool path variable name to
3777 avoid checks for one tool being affected by the results of running
3778 the length check on a previous tool.
3780 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
3781 match expression argument, as different greps have different
3782 regular expression flavours.
3783 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
3784 literals.
3785 (AC_PROG_EGREP): Pass 'EGREP$'.
3786 (AC_PROG_GREP): Pass 'GREP$'.
3788 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
3790 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
3791 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
3793 2004-03-29 Paul Eggert <eggert@twinsun.com>
3795 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
3796 Types, Specific Compiler Characteristics, System Services,
3797 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
3798 etc. consistently instead of 'long', 'short', 'unsigned' etc.
3799 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
3800 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
3801 Likewise.
3802 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
3803 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
3804 AC_TYPE_OFF_T): Likewise.
3805 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
3806 Likewise.
3808 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
3809 pacify libtool 1.5.2. Fix quoting problems in sed command.
3811 2004-03-28 Paul Eggert <eggert@twinsun.com>
3813 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
3814 now defines HAVE_DECL_TZNAME if it is declared, when
3815 HAVE_STRUCT_TM_TM_ZONE is not defined.
3816 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
3817 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
3818 for HAVE_TZNAME.
3820 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
3822 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
3823 superfluous backslashing of quotes (") in sed expressions;
3824 thanks to Paul Eggert.
3826 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
3828 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
3829 Fortran compiler is ifort, also added pghpf; thanks to Nelson
3830 H. F. Beebe for the bug report.
3832 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
3834 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
3835 quoted -cmdline argument in Portland Group compiler (bug
3836 reported by Jeffrey J. Barteet).
3838 2004-03-25 Kevin Ryde <user42@zip.com.au>
3840 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
3841 (Run Time): ... here, where it's now mentioned.

3845 * doc/autoconf.texi (autom4te Invocation): Language Autoconf
3846 inherits from language Autoconf-without-aclocal-m4.
3847 (Customizing autom4te): Adjust example; the cache must now be
3848 disabled for language Autoconf-without-aclocal-m4.
3850 2004-03-16 Paolo Bonzini <bonzini@gnu.org>
3851 Nathanael Nerode <neroden@twcny.rr.com>

3862 AC_CHECK_TOOLS.
3863 (Specifying Names): Document the reason for these future
3864 behavioral changes.
3865 * tests/mktests.sh: Do not generate tests for the
3866 new macros.
3867 * NEWS: Document these changes.
3869 * doc/autoconf.texi: Avoid macros with unbraced arguments,
3870 they make TeX hang up.

3874 * NEWS: New macro AC_CHECK_ALIGNOF.
3875 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
3876 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
3877 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
3878 vowel.
3879 (AC_CHECK_ALIGNOF): New macro.
3880 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
3881 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to
3882 those for sizeof.
3884 2004-03-03 Paul Eggert <eggert@twinsun.com>
3886 * bin/Makefile.am (edit): Don't use $< in a context where
3887 POSIX doesn't require support for it. Use $@.in instead.
3888 Problem reported by Anthony N. Frasso in
3889 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
3890 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
3892 2004-02-23 Gary V. Vaughan <gary@gnu.org>
3894 * bin/autoreconf.in (autoreconf_current_directory): Recognize LT_INIT
3895 from the next generation of Libtool.
3896 * lib/autom4te.in (Autoreconf-preselections): Ditto.
3898 2004-02-20 Alexandre Duret-Lutz <adl@gnu.org>
3900 * doc/autoconf.texi (Limitations of Usual Tools) <mkdir>: `mkdir -p'
3901 is not always thread-safe. Report from Nathanael Nerode.
3903 2004-02-18 Paul Eggert <eggert@twinsun.com>
3905 Fix a dependencies problem, stemming from a Autoconf 2.59 build
3906 problem on QNX reported by Stephen Rasku in
3907 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
3909 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
3910 $(m4sh_m4f_dependencies); this removes a FIXME.
3911 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
3912 (MAINTAINERCLEANFILES): Split into pieces,
3913 one per related section. Add $(srcdir)/wrapper.in.
3915 2004-02-09 Paul Eggert <eggert@twinsun.com>
3917 * doc/autoconf.texi (Setting Output Variables): Emphasize that
3918 AC_SUBST provides no portable way to escape literal newlines.
3920 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
3921 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
3922 Darwin uses -lcrt2.o and there's little point to cataloging all
3923 the system variants. Partial fix reported by Andreas Waechter in:
3924 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
3925 for bug reported by Nelson H. F. Beebe in:

3928 2004-02-04 Paolo Bonzini <bonzini@gnu.org>
3930 * doc/autoconf.texi (AU_DEFUN): Fix English,
3931 suggested by Paul Eggert.
3932 * lib/autoconf/autoupdate.m4: Correct reference to
3933 acobsolete.m4, suggested by Alexandre Duret-Lutz.
3935 2004-02-02 Paolo Bonzini <bonzini@gnu.org>

3938 refer to the correct file.
3939 * doc/autoconf.texi (AU_DEFUN): Describe more correctly
3940 the behavior of the third argument.
3941 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
3942 correctly the behavior of the third argument. Document
3943 what the three macros that AU_DEFUN defines do. Fix
3944 warning message when the third argument includes $0
3945 (reported by Alexandre Duret-Lutz).
3947 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
3948 Eric Sunshine <sunshine@sunshineco.com>
3949 Paul Eggert <eggert@twinsun.com>
3951 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
3952 (AS_INIT): Output shell initialization there. Removed optional
3953 parameter. Expand _AS_SHELL_FN_SPY.
3954 (AS_INIT_WITH_SHELL_FN): Removed.
3955 (_AS_SHELL_FN_SPY): New macro.
3956 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
3957 macros.
3958 (AS_SHELL_SANITIZE): Remove loop to find better shell
3959 and documentation for the parameter.
3960 (_AS_DETECT_BETTER_SHELL): Move it here.
3961 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
3962 (_AS_RUN): Move it here, support testing with eval.
3963 (AS_REQUIRE_SHELL_FN): Require shell functions when
3964 it is used.
3965 (_AS_LINENO_WORKS): Put around braces, we do not
3966 trigger the bash bug anymore.
3967 * lib/autotest/general.m4: Document M4SH-SANITIZE, do not
3968 use AS_INIT_WITH_SHELL_FN.
3969 * bin/autoconf.in, tests/wrapper.in: Regenerated.
3971 2004-01-30 Paolo Bonzini <bonzini@gnu.org>
3973 * bin/autoupdate.in: Trace AU_DEFINE instead of AU_DEFUN.

3988 * lib/autoconf/status.m4: Remove FIXME.
3989 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
3990 that the macro is not present anymore in the updated
3991 configure.ac.
3992 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
3993 of autoupdate.

3998 copyright years.
3999 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
4000 2003 (except 1997) to the list of copyright years. This undoes
4001 the 2003-05-22 change, which removed the older years from the list.
4002 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
4004 2004-01-27 Gary V. Vaughan <gary@gnu.org>

4010 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
4011 AC_PROG_GREP.
4012 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
4013 egrep and fgrep respectively if $GREP -E/-F don't work.
4014 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
4015 _AC_PROG_GREP, and AC_PROG_SED.
4016 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
4017 longest input length accepted by a command.
4018 (AC_PROG_SED): Use it.
4019 * doc/autoconf.texi (Particular Programs): Document the changes.
4020 * NEWS: Updated.
4022 2004-01-27 Paul Eggert <eggert@twinsun.com>
4024 * bin/autoconf.as ($version): Update copyright from 2003 to 2004.

4026 bin/autoscan.in, bin/autoupdate.in, bin/ifnames.in: Likewise.
4027 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Likewise.
4029 * Makefile.in, aclocal.m4, configure, bin/Makefile.in,
4030 bin/autoconf.in, config/Makefile.in, config/config.guess,
4031 config/config.sub, config/install-sh, config/mdate-sh,

4044 sources.
4046 2004-01-26 Paul Eggert <eggert@twinsun.com>
4048 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
4049 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
4050 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
4051 not <inttypes.h>. Problem reported by Tim Mooney in
4052 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
4053 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
4054 Likewise.
4056 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
4057 otherwise "make check" fails because it forbids cmp (I guess
4058 because cmp treats files as binary on DOS-like systems).
4060 * tests/mktests.sh: Update copyright date to 2004, since some tests
4061 have changed in 2004.
4063 2004-01-23 Gary V. Vaughan <gary@gnu.org>
4065 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
4066 non-truncating sed or gsed program in PATH.
4067 * tests/acprograms.at: Add it.
4068 * doc/autoconf.texi (Particular Programs): Document it.
4069 * NEWS: Updated.
4071 2004-01-15 Paul Eggert <eggert@twinsun.com>
4073 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
4074 -std1 disables some useful extensions on Tru64. Problem reported
4075 by N. Lichtmaier in
4076 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
4078 2004-01-14 Paul Eggert <eggert@twinsun.com>
4080 * doc/autoconf.texi (Programming in M4sh): Document that
4081 AS_MKDIR_P succeeds if the destination is a symbolic link

4104 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
4105 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
4106 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
4107 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
4108 AC_COMPILE_IFELSE, since we now assume our caller invokes
4109 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
4110 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
4111 of AC_RUN_IFELSE; this avoids the warning mentioned above.
4112 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
4114 2004-01-07 Paul Eggert <eggert@twinsun.com>
4116 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
4117 `"'...'"`, as it's confusing (and I suspect it may not work on
4118 some platforms). The code was incorrect anyway, as it assumed
4119 that \$ evaluated to itself in that context. Reported by
4120 Alexandre Duret-Lutz.
4122 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

4174 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
4175 -c -o might not work. From a suggestion by Kevin Ryde.
4176 (C Compiler, Generating Sources, Limitations
4177 of Usual Tools, Limitations of Make, Making testsuite Scripts):
4178 Don't put '-o' after non-options, as POSIX doesn't allow this.

4193 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by

4232 functions work.
4233 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
4234 does not work.
4235 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

4250 them on the fly.
4252 2003-11-24 Akim Demaille <akim@epita.fr>
4254 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

4572 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Remove files which might
4573 have been created when invoking the compiler.

4584 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
4585 Problem reported by Lars J. Aas in
4586 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
4587 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
4588 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
4589 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
4591 2003-09-26 Akim Demaille <akim@epita.fr>
4593 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
4594 directory for AC_CONFIG_COMMANDS' first argument exists.
4595 This makes valid the invocation of _AC_SRCPATH that follows.
4596 Reported by Eric Sunshine.
4597 * doc/autoconf.texi (Configuration Commands): Adjust.
4599 2003-09-26 Akim Demaille <akim@epita.fr>
4601 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
4602 Reported by Ralf Corsepius.
4604 2003-09-26 Akim Demaille <akim@epita.fr>
4606 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
4607 arguments.
4608 Actually, use AU_ALIAS.
4609 From Bruno Haible.
4611 2003-09-26 Paul Eggert <eggert@twinsun.com>
4613 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
4614 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
4615 Problem reported by Eric Sunshine in:

4620 The test suite are sometimes assigning timings incorrectly.
4621 Reported by Henk Krus.
4622 Diagnosed by Nicolas Joly.
4624 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
4625 AT_help_all.
4626 Instead of making AT_help a sequence of assignments to grow
4627 $at_help_all, just make AT_help_all be the growing contents of
4628 $at_help_all, and make a single assignment in...
4629 (AT_INIT): here.
4630 (at_times_skip): Flip the meaning and rename as...
4631 (at_times_p): this.
4632 (AT_INIT): When summarizing the test that ran, remove
4633 $at_times_file after use, and check it is present before trying to
4634 use it.
4636 2003-09-25 Akim Demaille <akim@epita.fr>
4638 Version 2.57d.
4640 * bin/Makefile.am (edit): Handle '@configure_input@'.
4641 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
4642 (ifnames): chmod -w.
4643 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
4644 executables, not bin/ executables! Otherwise all the magic needed
4645 to find non installed files is turned off. This caused a failure
4646 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
4647 as found in its environment (sent by tests/autoreconf): pointing
4648 to bin/autom4te that could not find its files.
4649 * tests/mktests.sh: Force the replacement of generated files, for
4650 the sake of "mv" program that are interactive when overwriting a
4651 -w file.
4652 * config/install-sh: Upgrade from CVS Automake.
4654 2003-09-23 Paul Eggert <eggert@twinsun.com>
4656 * doc/autoconf.texi (Limitations of Builtins): Document test -h
4657 versus test -L issues.
4659 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
4660 Paul Eggert <eggert@twinsun.com>
4662 Trivial change to support GCC's configuration procedure.
4663 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
4664 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
4665 about inconsistency if the preprocessor is set to give errors for
4666 any warning.
4667 * doc/autoconf.texi (C Compiler Characteristics): Document this.
4669 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
4671 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
4672 and XFile.pm from Automake.

4675 2003-09-12 Akim Demaille <akim@epita.fr>
4677 Version 2.57c.
4679 2003-09-12 Akim Demaille <akim@epita.fr>
4681 * config/config.guess, config/config.sub, config/missing,
4682 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
4683 from masters.
4685 2003-09-12 Akim Demaille <akim@epita.fr>
4687 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
4688 not asm/types.h.
4690 2003-09-11 Akim Demaille <akim@epita.fr>
4692 * doc/autoconf.texi (Header Portability): linux/random.h.
4693 From Peter Hendrickson.
4695 2003-09-10 Akim Demaille <akim@epita.fr>
4697 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
4698 willing to edit the output files.
4700 2003-09-10 Akim Demaille <akim@epita.fr>
4702 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
4703 and AC_FC_FREEFORM.
4704 * tests/mktests.sh: Skip AC_FC_SRCEXT.
4705 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
4707 2003-09-09 Akim Demaille <akim@epita.fr>
4709 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
4710 Reported by Gary Vaughan.

4716 trailing files.
4718 2003-09-07 Paul Eggert <eggert@twinsun.com>
4720 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
4721 Improve the accuracy of the wording about obsolescence.
4722 From a suggestion by Ian Lance Taylor in
4723 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
4725 2003-09-05 Paul Eggert <eggert@twinsun.com>
4727 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
4728 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
4730 2003-09-04 Akim Demaille <akim@epita.fr>
4732 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
4733 AC_FUNC_WAIT3.
4735 2003-09-04 Akim Demaille <akim@epita.fr>
4737 * bin/autom4te.in: Use &fatal where more appropriate than &error.
4738 (freeze): When exiting, use $exit_code.
4739 * lib/autoconf/fortran.m4: Comment changes.
4741 2003-09-04 Akim Demaille <akim@epita.fr>

4745 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
4747 Add support for newer Fortran dialects. The F77 interface is
4748 unchanged, and continues to support Fortran 77. New FC macros
4749 correspond to all the old F77 macros, with output variables FC,
4750 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
4751 available dialect, but older dialects can be specified. There are
4752 new macros AC_FC_SRCEXT to set the source extension, and
4753 AC_FC_FREEFORM to accept free-form source files.
4755 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
4756 New macros.
4757 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

4773 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
4774 Rewrite in terms of the above.
4775 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
4776 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
4777 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
4778 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.

4782 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
4783 Document problems with timestamp resolution that 'make', 'cp -p', and
4784 'touch -r' have.
4786 2003-08-27 Akim Demaille <akim@epita.fr>
4788 * tests/m4sugar.at (cross_warning): Make sure to enable the
4789 output, so that we can track spurious m4sugar output.
4790 * tests/local.at: Require 2.57.
4791 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
4792 are defaulted by AT_CHECK anyway.
4793 Use AT_CHECK_AUTOM4TE.
4794 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
4795 missing dnl.
4797 2003-08-27 Akim Demaille <akim@epita.fr>
4799 * bin/autoheader.in: Issue the "Using auxiliary..." message only
4800 when -Wobsolete is set.
4801 Set it on by default.
4802 Suggested by Klee Dienes.
4804 2003-08-27 Akim Demaille <akim@epita.fr>

4879 2003-08-21 Akim Demaille <akim@epita.fr>
4881 First stab at preserving warnings between calls to autom4te,
4882 including when the cache is used.
4884 There are still several issues: (i) there are too many runs of m4
4885 (one for include, one for warnings, and some more), (ii) warnings
4886 spreading on several lines are not handled gracefully, (iii) the
4887 code meant to have the call stack display for errors does not work
4888 (its handling should move from m4 to autom4te).
4890 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
4891 Use them.
4892 (@preselect): Add m4_warn.
4893 ($exit_status): Remove, use $exit_code.
4894 ($help): Use Autom4te::ChannelDefs::usage.
4895 (&handle_m4): No longer define the m4_warnings.
4896 At each run, extract and report the warnings.
4897 Always cache the result, including if the exit status is on
4898 failure, since if nothing changes, we should result in the same
4899 failure, hence we can use the cache.
4900 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
4901 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
4902 Remove.
4903 (m4_warn): Redefine as a do-nothing: it is its invocation that
4904 matters, as warnings are now reported via traces.
4905 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
4906 the contents of m4_warn: make it _call_ m4_warn, so that tracing
4907 the latter reveals calls to the former.
4909 Adjust the tests.
4911 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
4913 2003-08-21 Akim Demaille <akim@epita.fr>
4915 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

4918 2003-08-21 Akim Demaille <akim@epita.fr>
4920 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
4921 forward order.
4922 * lib/Autom4te/ChannelDefs.pm: Doc typos.
4923 (&parse_warnings): Accept a list of warning requests.
4924 (&usage): Return a string, not a side effect.
4925 (cross): New warning category.
4927 2003-08-21 Akim Demaille <akim@epita.fr>
4929 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
4930 (&require_configure_ac): Accept an optional directory argument.
4931 ($configure_ac): Remove.
4932 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
4933 (&catfile): Remove.
4934 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
4935 * bin/autoscan.in: Adjust.
4937 2003-08-20 Akim Demaille <akim@epita.fr>
4939 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
4940 Reported by Alexandre Duret-Lutz.
4942 2003-08-20 Akim Demaille <akim@epita.fr>
4944 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
4945 * bin/autom4te: Adjust.
4946 In particular, be Autoconf tools are really silent when properly
4947 working, bind the verbosity of the 'note' channel to $verbose.
4948 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
4949 (&xsystem, &contents): Remove, since they are exported by...
4950 * lib/Autom4te/FileUtils.pm: this.
4951 More perldoc.
4952 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
4953 * lib/Autom4te/FileUtils.pm: here.
4955 2003-08-20 Akim Demaille <akim@epita.fr>

5010 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
5011 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
5012 shorter column three. Add DESCRIPTION to log file content.
5014 2003-08-13 Derek Price <derek@ximbiot.com>
5016 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status

5047 2003-07-06 Bill Clarke <llib@computer.org>
5049 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): Cast pointer to
5050 'long', not 'int', for benefit of Sun's recent C++ compilers
5051 (trivial change). See:
5052 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00007.html
5053 (This really should be 'intptr_t', not 'long', but that would
5054 take more work.)
5056 2003-06-25 Akim Demaille <akim@epita.fr>
5058 * lib/Makefile.am (autom4te.cfg): Make it read only.
5059 Depend on Makefile since it contains substitutions.
5060 From Paolo Bonzini.
5061 * lib/autom4te.in (args): Add local.at? for Autotest args.
5062 This change was made on autom4te.cfg which is generated.
5063 Reported by Raja R. Harinath.
5065 2003-06-25 Akim Demaille <akim@epita.fr>
5067 * doc/autoconf.texi (Header Portability): sys/mount.h.
5068 From Gareth McCaughan.
5070 2003-06-23 Akim Demaille <akim@epita.fr>
5072 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
5073 not all of them. This fixes 1. the fact that when testing
5074 Autoconf there are many many config.log, 2. the incorrect use of
5075 top_srcdir to find config.log.
5076 Don't mix the detailed output of failed test with the summary of
5077 failures. Rather, append detailed log afterwards.
5079 2003-06-23 Akim Demaille <akim@epita.fr>
5081 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
5082 always run: output config.log on $at_group_log.
5084 2003-06-23 Akim Demaille <akim@epita.fr>
5086 * tests/torture.at (#define header templates): Don't use quotes in
5087 C++ comments as it puzzles Emacs' sh font-lock-mode.
5089 2003-06-23 Akim Demaille <akim@epita.fr>
5091 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
5092 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
5093 * tests/atspecific.m4: Rename as...
5094 * tests/local.at: This.
5095 * tests/suite.at: Move the globals into...
5096 * tests/local.at: here.
5097 * tests/Makefile.am: Adjust.
5098 * doc/autoconf.texi (testsuite Scripts): Adjust.
5100 2003-06-21 Kevin Ryde <user42@zip.com.au>
5102 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
5103 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
5104 ensuring we add -std1 for full-ANSI.
5106 * doc/autoconf.texi (hdrindex): New macro.
5107 Add index entries for portability of various standard header files.
5109 2003-06-20 Akim Demaille <akim@epita.fr>
5111 * configure.ac: Bump to 2.57b.
5113 2003-06-20 Akim Demaille <akim@epita.fr>
5115 Version 2.57a.
5117 2003-06-20 Akim Demaille <akim@epita.fr>
5119 * bin/autom4te.in: Don't rely on $HOME being defined.
5120 Reported by Marc Espie as PR/233.
5122 2003-06-20 Akim Demaille <akim@epita.fr>
5124 * lib/autotest/general.m4: Use at_times_file only if used.
5125 From Nicolas Joly.
5127 2003-06-20 Akim Demaille <akim@epita.fr>
5129 * config/config.guess, config/config.sub, config/elisp-comp,
5130 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
5131 Update from masters.
5133 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
5135 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
5136 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
5137 (TEST_SCRIPT): New diversion.
5138 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
5139 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
5140 (AT_INIT): Support for expected failures.
5142 2003-06-02 Akim Demaille <akim@epita.fr>
5144 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
5145 changes.
5146 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
5147 Autoconf nor Automake.
5148 (&contents): New, from Automake.
5149 PODify.
5151 2003-05-28 Paul Eggert <eggert@twinsun.com>
5153 * NEWS, doc/autoconf.texi (Particular Functions),
5154 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
5155 is the inverse of localtime.
5157 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
5159 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
5160 (handle_exec_errors): New function. Work around $! being
5161 altered by WEXITSTATUS.
5162 (xqx, xsystem): Use handle_exec_errors.
5164 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
5166 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
5167 Do not call `_exit()', simply modify `$?'.
5168 (xsystem): Reset $! before running system, and check it afterward.
5169 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
5170 63 for version mismatches.
5172 2003-05-23 Akim Demaille <akim@epita.fr>
5174 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
5175 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
5176 the middle of a line).
5177 * lib/m4sugar/m4sugar.m4: Likewise.
5178 Remove useless spaces in comments.
5180 2003-05-23 Akim Demaille <akim@epita.fr>
5182 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
5183 exit 63, so that we (or Automake's "missing") can tell the
5184 difference with a plain failure.
5185 * doc/autoconf.texi (Notices): Adjust.
5187 2003-05-23 Akim Demaille <akim@epita.fr>
5189 * Makefile.am, bin/Makefile.am, config/Makefile.am,
5190 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
5191 White spaces cleanup.
5193 2003-05-22 Jim Meyering <jim@meyering.net>
5194 Paul Eggert <eggert@twinsun.com>
5196 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
5197 Remove `#include <stdlib.h>' from the list; we should never
5198 make confdefs.h include <stdlib.h> or <cstdlib>, because the
5199 resulting namespace pollution would cause other tests to fail.
5200 Configure scripts run with some older versions of g++ and HP's
5201 aCC would fail due to such an #include. Problems reported by
5202 Matthew Mueller in <http://bugs.debian.org/120704> and by
5203 Keith Bostic in
5204 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
5205 In the test, use the test declaration before including <stdlib.h>,
5206 as that's closer to how it'll be used.
5208 2003-05-23 Akim Demaille <akim@epita.fr>
5210 * doc/autoconf.texi (Header Portability): ucred.h.
5211 From Ian Redfern.
5213 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5215 Overhaul Autotest's logging: generate separate log files
5216 in testsuite.dir/NNN/testsuite.log, and append them to
5217 testsuite.log instead of re-running the test verbosely.
5219 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
5220 file descriptor, write 0 to at_status_file instead of setting
5221 at_status=0, initialize some new variables (at_status_file,
5222 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
5223 to rerun the tests, instead append the at_group_log to the
5224 at_suite_log when a test fails.
5225 (AT_SETUP): pipe the test case's output into at_tee_pipe,
5226 with the AS_MESSAGE_LOG_FD redirected to stdout.
5227 (AT_CLEANUP): save the output status in $at_status_file
5228 and restore it, redirect the AS_MESSAGE_LOG_FD back to
5229 its original place.
5230 (AT_CHECK): since tests are run with a redirected stdout,
5231 and used to be re-run in verbose mode, turn some $at_verbose
5232 into echo, and don't redirect the output of testing stdout
5233 and stderr.
5235 * lib/autotest/autoconf.texi (testsuite Scripts): Update
5236 the name of the debugging directory and information about
5237 its contents.
5239 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
5241 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
5242 parameter.
5244 2003-05-22 Akim Demaille <akim@epita.fr>

5308 2003-05-17 Akim Demaille <akim@epita.fr>
5310 * lib/autoconf/functions.m4: Use the default includes so that
5311 memcmp be declared before being tested.
5312 Reported by Sander Niemeijer.
5313 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
5314 * doc/autoconf.texi (Default Includes): Document
5315 AC_INCLUDES_DEFAULT.
5317 2003-05-17 Akim Demaille <akim@epita.fr>
5319 * lib/autoconf/specific.m4: Include signal.h and unistd.h.

5354 and truncate.
5356 2003-05-06 Akim Demaille <akim@epita.fr>
5358 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
5359 longer updates aclocal.m4 if useless, (ii) if a file m4_included
5360 by aclocal.m4 is changed it might require the importing of another
5361 m4 extension file, i.e., aclocal must be run.
5363 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
5364 (&parse_args): Use --force with aclocal if required and supported.
5365 (&autoreconf_current_directory): Use &run_aclocal.

5371 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
5372 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
5373 argument instead of a file name, so that the request file remains
5374 open during the whole autom4te run.
5375 ($icache_file): New.
5376 (&freeze): Lock the $icache_file.
5378 2003-04-29 Derek Price <derek@ximbiot.com>
5380 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
5381 seperator with m4_append_uniq(). It doesn't work.
5382 (AT_CLEANUP): Add `;' to end of at_help_all.
5383 (AT_INIT): Allow --keywords to be specified more than once. When
5384 grepping $at_help_all for keywords, use the field and keyword
5385 seperators to ensure a complete keyword match. Alter at_prev handling
5386 to support the new --keywords behavior.
5388 2003-04-27 Karl Berry <karl@freefriends.org>
5390 * doc/autoconf.texi: Make the dir entries in the autoconf manual
5391 align better with others. I also made some of the individual
5392 entries on one line, for brevity and to make it easier for me to
5393 sort my dir-example file in the Texinfo distribution :).
5395 2003-04-12 Jim Meyering <jim@meyering.net>
5397 * NEWS: Mention the new macro.
5398 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

5433 New.
5434 Use them.

5436 (TEXI2DVI): Make it --batch.
5438 2003-03-31 Derek Price <derek@ximbiot.com>

5441 which removed the main loop.
5442 Thanks to Akim Demaille.
5444 2003-03-29 Akim Demaille <akim@epita.fr>

5447 that starts a GUI.
5448 From Ilya Zakharevich.
5450 2003-03-29 Akim Demaille <akim@epita.fr>
5452 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
5453 documentation to read is Autoconf's.
5454 Suggested by Paul Eggert.
5456 2003-03-28 Akim Demaille <akim@epita.fr>
5458 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
5459 reading the section "Present But Cannot Be Compiled" when the
5460 header causes problems.
5462 2003-03-28 Akim Demaille <akim@epita.fr>
5464 * tests/torture.at (Configuring subdirectories): Require aclocal
5465 1.4, otherwise the test fails, as it does support configure.ac.
5466 This fixes the "test 40 failed" bug reports.
5468 2003-03-28 Akim Demaille <akim@epita.fr>
5470 * doc/autoconf.texi (C Compiler): `#line' portability.

5499 sense. Verbosify the diversion definitions comment.
5501 2003-03-26 Derek Price <derek@ximbiot.com>
5503 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
5504 AS_PREPARE.

5525 file name for the m4 program, when it has an "exe" file extension.

5536 about `$<' in inference rules, it was a bogus interpretation of
5537 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
5538 Tru64 make in the "target lookup" section.
5539 (Automake): Automake 1.5+ no longer requires special tools to be
5540 present on the developer's host.
5542 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
5544 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
5545 to a shell that can handle redirection or quoting correctly.

5556 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
5557 to cope with DOS-style absolute paths, when constructing
5558 ${ac_make}.
5560 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
5561 When constructing paths with IFS=:, quote the path. If we're
5562 constructing a DOS-style absolute path, we don't want to split it
5563 on the colon.
5565 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
5566 in description.
5568 2003-02-25 Pavel Roskin <proski@gnu.org>

5580 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
5581 to fix a mismatch between example and discussion.
5583 2003-02-24 Kevin Ryde <user42@zip.com.au>
5585 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
5586 format starting with "-".
5588 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
5590 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
5591 is not portable inside Makefile.
5593 2003-02-20 Akim Demaille <akim@epita.fr>
5595 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
5596 compiler says yeah, but preproc says nope, compiler is right.
5597 Conversely, prompt the reader to send a bug report to the
5598 maintainers of the package, not of Autoconf.
5600 2003-02-20 Klee Dienes <kdienes@apple.com>
5602 * bin/autoreconf.in (autoreconf_current_directory): Properly

5608 $ac_prefix_program.
5609 From Larry Jones.
5611 2002-12-23 Paul Eggert <eggert@twinsun.com>
5613 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
5614 innocuous variant befor including <limits.h> or <assert.h>. This
5615 works around a bug reported by Albert Chin: HP-UX 11i
5616 (and earlier versions) have a <limits.h> that declares
5617 gettimeofday and many other functions.
5619 2002-12-03 Paul Eggert <eggert@twinsun.com>
5621 Version 2.57.
5623 * NEWS, configure.ac: Update version.
5625 * doc/fdl.texi: Upgrade to FDL version 1.2.
5627 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
5628 nontrivially in main's body, so that f's external declaration is
5629 not optimized away in AIX. This should fix the bug reported by
5630 Martin Frydl in
5631 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
5633 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
5634 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
5635 defined, to support freestanding compilers. This should fix the
5636 bug reported by Momchil Velkov in
5637 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
5639 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
5640 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

5645 * Makefile.maint (www-gnu): New macro.
5646 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
5647 the location has moved.
5649 2002-12-02 Martin Frydl <martin@systinet.com>
5651 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
5652 \(.*\) match is too long and there is something more to be checked.
5653 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
5655 2002-11-15 Akim Demaille <akim@epita.fr>

5662 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
5663 * configure.ac (AM_INIT_AUTOMAKE): here.
5664 Require 1.7.1.
5666 2002-11-14 Akim Demaille <akim@epita.fr>
5668 Version 2.55.
5670 * config/config.guess, config/config.sub, config/install-sh:
5671 Update from masters.
5673 2002-11-14 Akim Demaille <akim@epita.fr>
5675 * Makefile.maint: Sync with Bison, i.e.:
5676 (po-check): Scan .l and .y files instead of the
5677 .c and the .h files that they generate. This fixes the bug
5678 reported by Tim Van Holder in:
5679 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
5680 Look for N_ as well as for _. Try to avoid matching #define for
5681 N_ and _.
5682 From Paul Eggert.
5684 2002-11-14 Akim Demaille <akim@epita.fr>
5686 * doc/autoconf.texi (C Compiler): Compiling several files at once.
5687 From Paul Eggert and Albert Chin-A-Young.
5689 2002-11-14 Akim Demaille <akim@epita.fr>
5691 * doc/autoconf.texi (C Compiler): Solitary backslashes.
5692 From Paul Eggert and Albert Chin-A-Young.
5694 2002-11-14 Kevin Ryde <user42@zip.com.au>
5696 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
5697 than assigning in main, to avoid HP cc +O3 optimizing it away.
5699 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
5701 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
5702 option. Process --recheck after parsing all options. Pass -q
5703 option to configure on --recheck.
5704 (AC_OUTPUT): Pass -q from configure to config.status.
5705 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
5706 arguments to record.
5707 * doc/autoconf.texi (config.status Invocation): Document
5708 config.status -q option.
5710 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>

5713 Makefile.in if Makefile.am exists.

5735 Reported by Ezra Peisach.
5737 2002-11-05 Akim Demaille <akim@epita.fr>
5739 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
5740 Remove.
5741 We _have_ to stop using the old compatibility scheme that tried to
5742 avoid useless backslashes because Libtool 1.4.3 contains a
5743 AC_DEFINE([error_t], [int],
5744 [Define to a type to use for \`error_t' if it is not
5745 otherwise available.])
5746 We _have_ to quote the single quote and backslashes with \. The
5747 old compatibility scheme saw that ` was backslashed, and therefore
5748 did not quote the single quote. Hence before this patch, Autoconf
5749 was not compatible with Libtool.
5751 2002-11-04 Paul Eggert <eggert@twinsun.com>
5753 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

5758 2002-11-04 Akim Demaille <akim@epita.fr>
5760 Version 2.54c.
5762 * Makefile.maint (update, cvs-update, po-update, do-po-update):

5768 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
5769 from...
5770 (&autoreconf): here.
5771 ($help, $make, &parse_args, &autoreconf_current_directory):
5772 Support -m/--make.
5773 * doc/autoconf.texi (autoreconf Invocation): Adjust.

5789 (AT_CHECK_ENV): Make sure the `state-ls.before file exists.
5791 2002-10-31 Akim Demaille <akim@epita.fr>
5793 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
5794 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
5795 Make variable, not a shell variable.
5796 Suggested by Bruno Haible.
5798 2002-10-31 Akim Demaille <akim@epita.fr>
5800 * bin/autom4te.in (load_configuration): Reject #args out of any
5801 language.
5803 2002-10-31 Akim Demaille <akim@epita.fr>
5805 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

5817 Suggested by Tim van Holder.

5821 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
5822 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
5823 Problem reported by Bruno Haible.
5825 2002-10-29 Akim Demaille <akim@epita.fr>
5827 * doc/autoconf.texi (Header Templates): Put also in words what the
5828 pictures says to assist free style readers.
5829 (Customizing autom4te): s/--cache=/--cache /.
5831 2002-10-29 Akim Demaille <akim@epita.fr>
5833 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
5834 sys/wait.h.

5837 From Bruno Haible.
5839 2002-10-29 Akim Demaille <akim@epita.fr>

5854 * doc/autoconf.texi (Invoking autom4te): Rename as...

6059 `$ac_configure_args'.

6063 * doc/autoconf.texi: Use AC_CONFIG_HEADERS in examples.

6078 * doc/autoconf.texi (Limitations of Usual Tools): Remove incorrect

6081 2002-10-22 Akim Demaille <akim@epita.fr>
6083 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
6084 are a few warnings.
6085 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
6086 Quote for Perl '' strings, not "".
6087 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
6088 strings.
6090 2002-10-22 Akim Demaille <akim@epita.fr>
6092 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
6093 characters is a syntax warning now.
6094 (_AS_QUOTE): Accept $2 as list of characters to quote.
6095 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

6100 `@', to tickle Perl's lists.
6101 Reported by Carlos Velasco.
6103 2002-10-18 Akim Demaille <akim@epita.fr>
6105 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

6115 2002-10-17 Akim Demaille <akim@epita.fr>
6117 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.
6118 Fixes the `AC_ARG_VAR' test failures.

6138 Because of caching, some files that no longer exist and are no
6139 longer required can still cause errors.
6140 Reported by Alexandre Duret-Lutz.
6142 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
6143 to frozen files in @ARGV, as @ARGV must remain being a list of
6144 files. Rather, at M4 call sites, use this...
6145 (&files_to_options): New function.
6146 (&freeze): Use &error.
6147 (&up_to_date): If a file that was included according to the cache
6148 is no longer there, then the output is out dated.
6149 (&main): Don't even check whether a file is up to date is anyway
6150 --force is given.
6151 * tests/tools.at (autom4te cache): New.
6153 2002-10-16 Akim Demaille <akim@epita.fr>
6155 * bin/autoconf.as: Kill dead options.
6156 * bin/autoupdate.in (&parse_args): Kill old options.
6157 * bin/autoreconf.in (&parse_args): Remove dead options.
6158 Factor some code.
6159 (&autoreconf): Report the directories we enter *and leave*, so
6160 that error messages can be easily located, and use GNU Make
6161 format, so that Emacs' compile mode understands us.
6162 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
6163 if some file was changed instead of `print'.
6164 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
6165 (&parse_args): Remove the dead options.
6166 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

6172 2002-10-11 Akim Demaille <akim@epita.fr>

6175 check for compilability.
6177 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
6178 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

6182 * lib/autotest/general.m4 (AT_INIT): Include the failed test
6183 numbers in the Subject suggestion.

6197 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
6198 file name to enable parallel executions.
6199 From Sam Varshavchik.
6201 2002-10-08 Akim Demaille <akim@epita.fr>
6203 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
6204 aclocal invocation, as Gettext macros might not be visible to
6205 aclocal.
6206 Instead of blindly running autopoint, scan configure.ac (not the
6207 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
6208 Reported by Paul D. Smith.
6210 2002-10-08 Paul Eggert <eggert@twinsun.com>
6212 Work around problems found when POSIXLY_CORRECT=1 is set.
6213 None of this seems to have anything to do with POSIX, really,
6214 but it's how Perl getopt works.
6215 * bin/autom4te.in (parse_args): Configure GetOpt with
6216 "permute", too.
6217 * doc/autoconf.texi (Invoking autom4te):
6218 --warning -> --warnings.
6219 * lib/autom4te.in: --warning -> --warnings.

6238 2002-09-28 Akim Demaille <akim@epita.fr>
6240 * tests/torture.at (Configuring subdirectories): Be robust to
6241 users who use config.site to require for a cache: in this case,
6242 the two last configure runs, using two different sets of
6243 arguments, trigger a legitimate error.
6245 2002-09-28 Akim Demaille <akim@epita.fr>
6247 * tests/m4sh.at (Functions Support, Functions and return Support):
6248 New.

6261 (tm_zone): Move their rules to...
6262 * lib/autoconf/types.m4: here, using AN_ macros.
6263 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
6264 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
6265 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
6266 * lib/autoconf/programs.m4: here.

6278 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
6279 (.m4.m4f): Don't pass --prepend-include, since that's done by
6280 tests/autom4te itself.
6281 * lib/autoscan/Makefile.am: Include freeze.mk.
6282 (autoscan.list): New target --this file is no longer a source.
6283 (autoscan.pre): New file.
6285 2002-09-28 Akim Demaille <akim@epita.fr>
6287 * bin/autoscan.in (@kinds): Make them singular.
6288 Adjust all uses.
6289 (&init_tables): When --debug, report the list of rules to ease
6290 tracking changes in autoscan.list.
6291 * lib/autoscan/autoscan.list (function): Strip comments, sort.
6293 2002-09-28 Akim Demaille <akim@epita.fr>

6304 * lib/autoscan/identifiers, lib/autoscan/makevars,
6305 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
6306 `functions' line is now prefixed with `function:'.
6307 * bin/autoscan.in (&init_tables): Adjust.
6309 2002-09-28 Akim Demaille <akim@epita.fr>
6311 From now on, autoscan files must always map a macro name to a
6312 word: there is no `default' macro for autoscan.
6314 * bin/autoscan.in (&init_tables): Reject entries with no macro at
6315 all.
6316 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
6317 explicit.
6319 2002-09-28 Akim Demaille <akim@epita.fr>
6321 * bin/autoscan.in (%c_keywords): Remove.
6322 (&used): Keep only track of the words we might be interested in.

6353 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
6354 Reported by Ralf Corsepius.
6355 * doc/autoconf.texi (autoreconf Invocation): Likewise.
6357 2002-09-26 Akim Demaille <akim@epita.fr>
6359 Single suffix rules and seperated dependencies are not portable.
6361 * doc/autoconf.texi (Installation Directory Variables): Update.
6362 (Limitations of Make): Some about `Single Suffix Rules and

6372 2002-09-24 Paul Eggert <eggert@twinsun.com>

6377 * bin/Makefile.am (SUFFIXES, .in): Remove.
6378 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

6381 2002-09-16 Akim Demaille <akim@epita.fr>
6383 i960 compilers create `b.out' files by default.
6384 Reported by Ralf Corsepius.
6386 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.

6405 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest

6407 Suggested by Guido Draheim.
6409 2002-09-13 Akim Demaille <akim@epita.fr>
6411 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
6412 (chdir_init) might hang when stat'ing mounted directories.

6415 2002-09-12 Akim Demaille <akim@epita.fr>
6417 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
6418 the lists.
6420 2002-09-12 Akim Demaille <akim@epita.fr>
6422 * doc/autoconf.texi (Defining Symbols): Present two different
6423 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

6428 * doc/autoconf.texi: Review grammar and punctuation.

6433 grammatical typos.
6434 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
6435 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
6436 is obsolescent.
6438 2002-09-11 Akim Demaille <akim@epita.fr>
6440 * doc/autoconf.texi (Questions): Rename as...
6441 (FAQ): this.

6456 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
6457 `duplicates', since the algorithm was too naive and could keep
6458 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
6459 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
6460 Reported by Ralf Corsepius.

6462 cases.
6464 2002-09-09 Akim Demaille <akim@epita.fr>

6470 * doc/autoconf.texi (Generic Functions): Clarify the replacement
6471 directory definition.
6472 Reported by Andreas Schwab and Jim Meyering.
6474 2002-09-06 Akim Demaille <akim@epita.fr>

6477 precious variables are.
6478 Suggested by Pontus Skoeld.
6480 2002-09-05 Akim Demaille <akim@epita.fr>
6482 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
6483 (ifnames, autoscan, autom4te): Since we don't only depend on
6484 configure.ac variables (such as VERSION etc.), but also on prefix
6485 and so forth, depend on Makefile, not configure.ac.
6486 Reported by Alexandre Duret-Lutz.
6487 * doc/autoconf.texi (Installation Directory Variables): Adjust.
6489 2002-09-05 Kevin Ryde <user42@zip.com.au>
6491 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes

6509 * configure.ac: Bump to 2.53d.
6510 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
6511 as of today, on Automake's team suggestion.
6513 2002-09-03 Akim Demaille <akim@epita.fr>
6515 Version 2.53c.
6517 2002-09-02 Akim Demaille <akim@epita.fr>
6519 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
6520 SITE_MACRO_DIR.
6521 * configure.ac: Disable SITE_MACRO_DIR.

6525 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
6526 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
6527 Also, tweak grammar: s/make sure to/be sure to/.
6529 2002-09-02 Paul Eggert <eggert@twinsun.com>
6531 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
6532 directory names are generally preferable to physical names.
6534 2002-09-02 Akim Demaille <akim@epita.fr>
6536 * lib/Autom4te/General.pm (&update_file): s/die/error/.
6537 Reported by Raja R. Harinath.
6538 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
6539 * bin/autoupdate.in: Use error instead of die.
6541 2002-09-01 Paul Eggert <eggert@twinsun.com>
6543 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
6544 ordinary shell concatenation rather than echo+tr+sed command that
6545 runs afoul of a long-line-related sed bug in Solaris 8.
6547 * bin/autoheader.in (parse_args): --warning -> --warnings.
6549 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
6550 stdout, as traditional "ls" does.
6551 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
6552 _AC_COMPILER_EXEEXT_O): Likewise.
6553 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
6555 * bin/autoconf.as: Add --prepend-include option. This patch was
6556 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
6557 but bin/autoconf.in is generated automatically from bin/autoconf.as.
6559 * bin/autoconf.in, configure: Regenerate.
6561 * doc/autoconf.texi (Special Shell Variables): Mention
6562 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
6564 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
6565 MAILPATH and set PS1, PS2, PS4 to default values, to work
6566 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
6567 For LC_ALL etc, first try to set to "C" as POSIX requires and as
6568 the Autoconf documentation specifies; fall back to "unset" only if
6569 this fails. Use a shell for-loop for this rather than an m4 loop,
6570 to shorten the output script.
6572 2002-08-30 Paul Eggert <eggert@twinsun.com>
6574 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
6575 1003.1-2001's requirements for CDPATH. Give a simpler workaround
6576 for the CDPATH problem. Document PWD.
6577 (Limitations of Builtins): Document the problem that "cd $foo" and
6578 "ls $foo" may refer to different directories in shells conforming
6579 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
6580 example, since the old example is now out of date.
6582 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
6583 FOO" and "ls FOO" talk about different directories; this catches
6584 problems when POSIX 1003.1-2001 "cd" fails due to symlink
6585 spaghetti.
6587 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
6588 of rolling our own unset.
6589 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
6590 in practice we needn't worry about CDPATH if unset doesn't work.
6592 * Makefile.in, aclocal.m4, bin/Makefile.in,
6593 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
6594 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
6595 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
6596 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
6597 tests/Makefile.in: Regenerate with Automake 1.6.3.
6599 * config/config.guess, config/config.sub, config/mkinstalldirs:
6600 Update.
6602 * configure: Regenerate with self.
6604 2002-08-30 Kevin Ryde <user42@zip.com.au>
6606 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
6607 default output.
6609 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
6611 * bin/autom4te.in (Request::load): Correctly test for "do" read
6612 failure.
6614 2002-08-29 Akim Demaille <akim@epita.fr>
6616 * lib/Autom4te/General.pm (&xqx): New.
6617 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
6618 hand, which is not portable.
6619 (&error): New.
6620 * bin/autom4te.in: Use them.
6621 Use &error instead of die.
6622 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
6623 Adjust.
6625 2002-08-17 Paul Eggert <eggert@twinsun.com>
6627 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
6628 default list of compilers to try, since it was long ago superseded
6629 by the ksh fc builtin. Suggested by Steven G. Johnson.
6631 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
6633 * doc/autoconf.texi (Invoking autom4te): End the option table,
6634 fixing a bug introduced by the previous patch.
6635 (Limitations of Make): Add a 'target lookup' subentry in the
6636 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
6638 2002-07-29 Mark D. Roth <roth@feep.net>
6640 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
6641 options and use $AUTOM4TE_PATH.
6642 * doc/autoconf.texi: Remove documentation of autom4te
6643 --include-envvar and --site-macro-subdir options and document
6644 use of $AUTOM4TE_PATH.
6645 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
6646 arguments from each language section.
6648 2002-07-29 Paul Eggert <eggert@twinsun.com>
6650 * doc/install.texi: Include copyright symbol in copyright notice.
6652 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
6653 Replace with:
6654 (AM_MAKEINFOFLAGS): New macro.
6655 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
6656 * Makefile.am (INSTALL): Use the new macros.
6657 Use -o rather than --output, since "missing" does not grok --output.
6659 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
6661 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
6662 comments do not always work. Never trust the exit status of
6663 `make -k'.
6665 2002-07-24 Kevin Ryde <user42@zip.com.au>
6667 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
6668 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
6670 2002-07-23 Paul Eggert <eggert@twinsun.com>
6672 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
6673 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
6674 apparently treats PATH="nonexistent" as if it contained ".".
6675 Bug reported by Stefan `Sec' Zehl.
6677 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
6679 * doc/autoconf.texi (Limitations of Make): Mention the special
6680 handling of the obj/ directory by BSD make.
6682 2002-07-20 Kevin Ryde <user42@zip.com.au>
6684 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
6685 backslashes.
6687 2002-07-19 Akim Demaille <akim@epita.fr>

6696 2002-07-18 Akim Demaille <akim@epita.fr>
6698 Version 2.53b.
6700 2002-07-18 Akim Demaille <akim@epita.fr>
6702 * config/config.guess, config/config.sub: Update.
6704 2002-07-18 Akim Demaille <akim@epita.fr>
6706 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
6707 Automake's parts.

6713 2002-07-18 Akim Demaille <akim@epita.fr>,
6714 Alexandre Duret-Lutz <duret_g@epita.fr>
6716 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
6717 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.

6726 * lib/autoconf/functions.m4 (AC_FUNC_FORK): Don't set
6727 ac_cv_func_fork_works before running _AC_FUNC_FORK, do it if the

6732 * lib/Autom4te/General.pm (find_file): Browse the directories in
6733 the order they are given.

6753 macro directory, remove note that include path directories are
6754 used in reverse order, and document --prepend-include option.
6755 * lib/autom4te.in: Use --prepend-include instead of --include.
6756 * tests/wrapsh.in: Use --prepend-include instead of --include.

6794 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
6796 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
6797 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
6798 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
6799 so that Emacs setups GNU style for perl-mode and cperl-mode.
6801 2002-06-27 Paul Eggert <eggert@twinsun.com>
6803 * config/install-sh: Quote $src. Prefer || to test's -o option,
6804 as per "Limitations of Builtins".
6805 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
6806 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
6808 * tests/mktests.sh: Use grep instead of fgrep, as per
6809 "Limitations of Builtins".
6811 2002-06-15 Paul Eggert <eggert@twinsun.com>
6813 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
6814 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
6815 so that we consistently test the just-built programs.
6816 * tests/wrappl.as: Likewise.
6818 2002-06-12 Paul Eggert <eggert@twinsun.com>
6820 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
6821 name, so that symlinks to 'autoconf' work properly. Bug reported
6822 by Bruno Haible.
6823 * bin/autoheader.in (AUTOM4TE): Likewise.
6824 * bin/autoreconf.in (autoconf, autoheader): Likewise.
6825 * bin/autoscan.in (autom4te): Likewise.
6826 * bin/autoupdate.in (autom4te): Likewise.
6828 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
6829 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
6830 on Solaris 2.5.1.
6832 2002-06-11 Andreas Schwab <schwab@suse.de>
6834 * doc/autoconf.texi: Add more dir entries.
6836 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
6838 * bin/autom4te.in ($cache): Don't define using `$me', the name
6839 of the cache should not depend on the name under which autom4te
6840 was installed.
6842 2002-06-07 Akim Demaille <akim@epita.fr>
6844 * tests/tools.at (autoconf: forbidden tokens, basic)
6845 (autoconf: forbidden tokens, exceptions): Adjust to the change of
6846 words in autom4te.in.
6848 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
6850 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
6851 _AC_LANG_PROGRAM_C_F77_HOOKS.
6853 2002-06-07 Akim Demaille <akim@epita.fr>
6855 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
6856 rename as...
6857 (AC_REPLACE_FNMATCH): this.
6858 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
6859 AC_FUNC_FNMATCH_GNU.
6861 2002-06-07 Akim Demaille <akim@epita.fr>
6863 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
6864 Rosetta Stone for Unix.
6866 2002-06-07 Akim Demaille <akim@epita.fr>
6868 * bin/autom4te.in (warn_forbidden): When rejecting a token,
6869 suggest m4_pattern_allow.
6870 Suggested by Adam J. Richter.
6872 2002-06-07 Akim Demaille <akim@epita.fr>
6874 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
6875 ac_config_libobj_dir.
6876 (AC_CONFIG_LIBOBJ_DIR): New.
6877 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
6878 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
6879 Use ac_config_libobj_dir to find the replacement files.
6880 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...
6881 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU, AC_REPLACE_FNMATCH)
6882 (AC_REPLACE_FNMATCH_GNU): these.
6883 (AC_FUNC_GETLOADAVG): Use ac_config_libobj_dir.
6884 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
6885 * tests/mktests.sh (ac_exclude_list): Don't check
6886 AC_FUNC_GETLOADAVG as it requires getloadavg.c which is not shipped.
6888 2002-06-06 Paul Eggert <eggert@twinsun.com>
6890 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
6891 if ln doesn't work.
6892 * NEWS: Likewise.
6893 * doc/autoconf.texi (Configuration Links): Likewise.
6894 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
6896 2002-06-05 Paul Eggert <eggert@twinsun.com>
6898 * config/config.guess, config/config.sub, config/texinfo.tex:
6899 Update from masters.
6901 2002-05-29 Paul Eggert <eggert@twinsun.com>
6903 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
6904 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
6905 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

6913 * tests/atspecific.m4 (AT_CONFIGURE_AC, AT_CHECK_DEFINES): Likewise.
6914 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
6916 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
6917 * doc/autoconf.texi (Particular Programs): Document them.
6918 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
6919 * NEWS: Likewise.
6921 2002-05-27 Paul Eggert <eggert@twinsun.com>
6923 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
6924 * NEWS, doc/autoconf.texi (Particular Types): Document it.
6925 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
6926 instead of AC_MBSTATE_T, which never existed.
6928 2002-05-23 Akim Demaille <akim@epita.fr>
6930 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
6931 version of Autoconf that is discussed.
6933 2002-05-22 Paul Eggert <eggert@twinsun.com>
6935 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
6936 from the default list of compilers to try. Suggested by
6937 Kate Hedstrom.
6938 * NEWS: Document the above.
6939 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
6941 2002-05-17 Paul Eggert <eggert@twinsun.com>
6943 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
6944 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
6945 This improves on an earlier suggestion by H. Peter Anvin.
6947 2002-05-16 Paul Eggert <eggert@twinsun.com>
6949 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
6950 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
6951 Both macros now accept an optional source-dir arg.
6952 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
6954 * NEWS: Document this.
6955 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
6957 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
6958 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
6959 not for GNU extensions; this undoes part of the 2000-11-03 change,
6960 reverting to 2.13-compatible behavior.
6961 Add new optional argument DIR.
6962 (AC_FUNC_FNMATCH_GNU): New macro.
6964 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
6966 2002-05-08 Paul Eggert <eggert@twinsun.com>
6968 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
6969 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
6970 and it causes a 'test' syntax error if it fails.
6971 Bug reported by Stephen Gildea.
6973 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
6974 If prototypes are supported, use them to check this at compile-time,
6975 instead of trying to check it at run-time. If we must do a run-time
6976 check, assume that setvbuf is standard when cross-compiling, as
6977 nonstandard setvbuf occurs only on ancient and unlikely hosts.
6978 Bug reported by Paul D. Smith.
6980 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
6981 argument specifying location of getloadavg.c. This removes a
6982 FIXME. This idea was taken from Jim Meyering's implementation in
6983 textutils.
6984 * doc/autoconf.texi (Particular Functions): Document this.
6985 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
6986 that's what the code does; this fixes a bug reported by
6987 Paul D. Smith.
6989 2002-05-03 Akim Demaille <akim@epita.fr>
6991 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
6992 autopoint instead of gettextize.
6993 ($uses_alocal): Rename as...
6994 ($uses_aclocal): this.
6995 * doc/autoconf.texi (autoreconf Invocation): Adjust.

6998 2002-05-03 Akim Demaille <akim@epita.fr>
7000 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
7002 2002-04-29 Paul Eggert <eggert@twinsun.com>
7004 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
7005 files to be 1 second older; just set them to be the same time.
7006 Also, sleep 1 second after the first aclocal, to work around
7007 problems with sub-second time stamps on the input files.
7009 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
7011 * doc/autoconf.texi: Mention "set -e -x" lossage
7012 under node "Limitations of Builtins".
7014 2002-04-29 Akim Demaille <akim@epita.fr>
7016 * doc/install.texi: Better wording for setting variables when
7017 running configure.
7018 From Christian Cornelssen.
7020 2002-04-29 Akim Demaille <akim@epita.fr>
7022 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
7023 of lack of $LINENO support, then the test will compare the $LINENO
7024 in testsuite vs. the lineno in the test file. This is wrong, of
7025 course.
7026 Be sure to protect it.
7027 Reported by Patrick Welche.
7029 2002-04-25 Akim Demaille <akim@epita.fr>
7031 * doc/autoconf.texi (Obsolete Macros): Typo.
7032 Reported by Vladimir Volovich.
7034 2002-04-25 Akim Demaille <akim@epita.fr>
7036 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
7037 than some of the input files, hence, on the second run of aclocal,
7038 if some of its input are younger, make them older.
7039 Suggested by Paul Eggert.
7041 2002-04-25 Akim Demaille <akim@epita.fr>
7043 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

7046 2002-04-25 Akim Demaille <akim@epita.fr>
7048 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
7049 and ac_subst_vars be sh variables containing the list of
7050 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
7051 DEFAULT diversion.
7052 (_AC_INIT_PREPARE): Use them to log them.
7053 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
7054 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
7055 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
7056 _AC_SUBST_FILES and _AC_SUBST_VARS.
7057 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
7059 2002-04-24 Akim Demaille <akim@epita.fr>
7061 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
7062 autoheader, so that automake does not complain about a missing
7063 config.h.in that was to be created.
7065 2002-04-23 Akim Demaille <akim@epita.fr>
7067 * bin/autoheader.in (parse_args): --warning takes an argument.
7068 Fixes PR/220.

7072 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out

7117 Minor spelling and grammar fixes.
7119 * doc/autoconf.texi: Follow the outline suggested in the GNU
7120 Sample Texts sections of the Texinfo 4.2 manual. Most
7121 importantly, this makes sure that the copyright notices appear in
7122 all output formats. You probably need Texinfo 4.2 to generate
7123 the manual now.
7125 Fix some bugs when using "$@" when there might be zero positional
7126 arguments in cases where this matters.

7149 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
7151 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs

7160 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
7161 workaround for ${1+"$@"}.
7162 * doc/autoconf.texi (Shell Substitutions): Explain it.
7163 From Oliver Kiddle and Peter Stephenson.
7165 Have M4sh perform minimal shell sanitizing.
7167 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
7168 part into...
7169 (_AS_PREPARE): this new macro.
7170 (AS_PREPARE): New.
7171 (AS_INIT): Invoke AS_SHELL_SANITIZE.
7172 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
7174 Adjust Autoconf and Autotest.
7176 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
7177 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
7178 * lib/autotest/general.m4 (AT_INIT): Likewise.
7179 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
7180 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
7181 AS_SHELL_SANITIZE.
7183 Use this M4sh to generate Autoconf's shell scripts.
7185 * tests/wrapsh.as: New, precursor of wrapsh.in.
7186 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
7187 on Autotest and M4sh.
7188 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
7189 (wrapsh.in): New target.
7190 * bin/autoconf.as: New, precursor of autoconf.in.
7191 (autoconf.in): New target.
7193 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

7196 with indented comments in rules.
7198 2002-04-09 Andreas Schwab <schwab@suse.de>
7200 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
7201 ac_top_builddir when setting ac_abs_top_builddir.
7203 2002-04-06 Kevin Ryde <user42@zip.com.au>
7205 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
7206 (Portable Shell): Cross reference to Systemology.
7208 2002-04-05 Akim Demaille <akim@epita.fr>
7210 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
7211 directories when descending in a SUBDIRS.
7212 Reported by Ezra Peisach.
7214 2002-04-04 Andreas Schwab <schwab@suse.de>
7216 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
7217 contains no literal separators.
7219 2002-04-03 Akim Demaille <akim@epita.fr>
7221 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
7222 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
7223 Use dnl, not the KILL diversion.
7224 Extracted from...
7225 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
7226 (AC_CONFIG_LINKS): here.
7227 Adjust.
7228 Don't use the KILL diversion, as it kills spurious output, which
7229 results in failures being hidden.
7230 Use m4_defn where appropriate.
7231 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
7232 after the second argument.
7233 Use m4_defn.
7234 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
7235 syntax, as it is provided by M4sugar.
7236 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
7238 2002-04-03 Andreas Schwab <schwab@suse.de>
7240 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
7241 expanded if $# <= 2.
7243 * bin/autoreconf.in (autoreconf): Run automake after rerunning
7244 aclocal.
7246 2002-04-03 Akim Demaille <akim@epita.fr>
7248 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)

7250 Also recognize *.bb and *.bbg as compilation byproducts.
7251 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
7252 (_AC_COMPILER_OBJEXT): Use them.
7253 Fixes Debian #138666.
7255 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
7257 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
7259 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
7260 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
7261 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
7262 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
7263 (AC_C_CONST): Same.
7264 (AC_C_INLINE): Same.
7265 (AC_C_PROTOTYPES): Same. Require AC_PROG_CC instead.
7266 * doc/autoconf.texi, NEWS: Document.
7267 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
7268 AC_C_CROSS.

7273 _AS_MKDIR_P_PREPARE.
7275 2002-03-28 Kevin Ryde <user42@zip.com.au>
7277 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
7278 to avoid versions of HP C which don't allow that.
7280 2002-03-27 Paul Eggert <eggert@twinsun.com>
7282 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
7283 (AS_SHELL_SANITIZE): Invoke it.
7284 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
7286 2002-03-26 Akim Demaille <akim@epita.fr>
7288 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
7290 2002-03-26 Akim Demaille <akim@epita.fr>
7292 * doc/autoconf.texi (Introduction): The GNATS base moved.
7294 2002-03-25 Paul Eggert <eggert@twinsun.com>
7296 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
7297 as POSIX requires, as it doesn't work with Zsh.
7298 * doc/autoconf.texi (Assignments): Document the problem.
7300 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
7302 * doc/autoconf.texi (Limitations of Make): Mention more issue
7303 about VPATH, overriding of macros in sub-makes, and handling of
7304 SHELL.
7306 2002-03-21 Paul Eggert <eggert@twinsun.com>
7308 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
7309 problem with here-document buffer boundaries.
7311 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
7312 when reinvoking the shell, to work around problems with installers
7313 who put strange things like "cd" commands in their environments.
7315 2002-03-19 Akim Demaille <akim@epita.fr>
7317 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
7318 From Aaron Ucko.
7320 2002-03-19 Akim Demaille <akim@epita.fr>

7323 invocations.
7324 From Nicolas Joly.
7326 2002-03-19 Akim Demaille <akim@epita.fr>
7328 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
7329 From Nishio Futoshi.
7331 2002-03-19 Akim Demaille <akim@epita.fr>
7333 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
7335 2002-03-18 Paul Eggert <eggert@twinsun.com>
7337 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
7338 (Limitations of Usual Tools): Add mkdir section.
7340 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
7341 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
7342 back on AS_DIRNAME to compute prefixes otherwise; this is
7343 roughly what mkinstalldirs does. That way, we need not have
7344 our own filename disassembler. The old disassembler did not
7345 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
7347 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
7348 Create at_test_all by a series of assignments,
7349 not by a single assignment of a long string. The latter causes ksh
7350 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
7351 presumably because of a buffer overrun.
7353 2002-03-14 Paul Eggert <eggert@twinsun.com>
7355 * lib/autotest/general.m4 (at_times_skip):
7356 Renamed from at_times. Now a boolean.
7357 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
7358 says 'times: not found'.
7360 2002-03-14 Akim Demaille <akim@epita.fr>
7362 * bin/autoreconf.in (&study_gettextize): New.
7363 (&autoreconf): Handle newest gettextize.
7364 Rerun aclocal if needed.
7365 Suggested by Andreas Schwab.
7367 2002-03-13 Akim Demaille <akim@epita.fr>
7369 * doc/autoconf.texi (Special Shell Variables): More about IFS.
7371 2002-03-13 Akim Demaille <akim@epita.fr>
7373 * doc/autoconf.texi (Header Portability): New.
7374 Add information about stdint.h and inttypes.h from Paul Eggert.
7376 2002-03-13 Akim Demaille <akim@epita.fr>
7378 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
7379 -p'.
7380 From Bob Proulx.
7382 2002-03-12 Akim Demaille <akim@epita.fr>
7384 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
7385 m4_require.
7387 2002-03-11 Andreas Schwab <schwab@suse.de>
7389 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
7390 does not do it if --with-lispdir is given.
7392 2002-03-08 Akim Demaille <akim@epita.fr>
7394 Version 2.53.
7396 2002-03-08 Akim Demaille <akim@epita.fr>
7398 * doc/autoconf.texi (Subdirectories): Clarify that the
7399 subdirectory should exist.
7401 2002-03-08 Akim Demaille <akim@epita.fr>
7403 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
7405 2002-03-08 Akim Demaille <akim@epita.fr>
7407 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
7408 aliases the actual variables, and modifications of the former
7409 affect the latter.
7411 2002-03-08 Akim Demaille <akim@epita.fr>
7413 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
7414 because of C-c: have m4 output in tmp files, then mv them.
7416 2002-03-08 Akim Demaille <akim@epita.fr>
7418 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
7419 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
7420 * bin/ifnames.in: Copyright update.
7422 2002-03-08 Akim Demaille <akim@epita.fr>
7424 * doc/autoconf.texi (Invoking autom4te): New.
7426 2002-03-05 Akim Demaille <akim@epita.fr>
7428 * doc/autoconf.texi (Specifying Names): Clarification suggested by
7429 Kevin Ryde.
7431 2002-03-05 Akim Demaille <akim@epita.fr>
7433 Version 2.52i.
7435 2002-03-04 Akim Demaille <akim@epita.fr>
7437 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
7438 * lib/autoconf/general.m4 (AC_INIT): More informative error
7439 message for LIBOBJ.
7441 2002-03-04 Akim Demaille <akim@epita.fr>
7443 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
7444 parallel builds.
7446 2002-03-04 Akim Demaille <akim@epita.fr>
7448 * doc/autoconf.texi (Transforming Names): Equality between target
7449 and host is irrelevant.
7450 (Specifying Names, Canonicalizing): Remove all references to the
7451 backward compatibility hooks. Rather, collect them all into...
7452 (Hosts and Cross-Compilation): this new section.
7453 * doc/install.texi (System Type): Ditto.
7454 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
7455 that `--host' implies cross-compilation.
7457 2002-03-04 Akim Demaille <akim@epita.fr>
7459 * doc/autoconf.texi (Evaluation Macros): New.
7460 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
7461 useless.
7462 (_m4_foreach): Define the variant with immediate evaluation so
7463 that it contains exactly the items, not an expression which
7464 evaluation is the current item.
7465 (m4_re_string, m4_re_word): Don't over quote them.
7467 2002-03-04 Akim Demaille <akim@epita.fr>
7469 Instead of having stacking `shift's evaluated at the end, let
7470 `foreach' loops immediately evaluate them.
7472 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
7473 $*. This is the n-th time I change my mind, but hopefully this is
7474 the last...
7475 (m4_lquote): New.
7476 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
7477 efficient.
7478 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
7479 it was only a hack for m4_text_wrap.
7480 (m4_car2): Remove, replaced by...
7481 (m4_cdr): New.
7482 (_m4_foreach): Adjust.
7483 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
7484 m4_bpatsubst for clarification.

7506 message to be sent.
7508 2002-02-28 Kevin Ryde <user42@zip.com.au>

7512 2002-02-25 Akim Demaille <akim@epita.fr>
7514 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
7515 From Akinori Musha.
7517 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
7519 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
7520 translate \r\n to \n.

7533 2002-02-07 Akim Demaille <akim@epita.fr>
7535 Fix Autoconf PR/207:
7536 AC_PREFIX_PROGRAM fails with dashed program names
7538 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
7539 variable when looking for the prefix program.
7540 Now it also works for shell variables.
7542 2002-02-07 Akim Demaille <akim@epita.fr>
7544 * doc/autoconf.texi (Limitations of Builtins): More about
7545 case/esac.
7547 2002-02-06 Akim Demaille <akim@epita.fr>
7549 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
7550 case/esac, some shells don't support it.
7551 Reported by Zack Weinberg.
7552 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
7554 2002-02-06 Akim Demaille <akim@epita.fr>
7556 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
7557 sure not to introduce newlines in at_groups.
7558 * lib/autotest/Makefile.am (autotest.m4f): Typo.
7560 2002-02-06 Akim Demaille <akim@epita.fr>
7562 * tests/torture.at (Configuring subdirectories): Skip if aclocal
7563 is not available.
7565 2002-02-05 Paul Eggert <eggert@twinsun.com>
7567 * doc/autoconf.texi (Specific Compiler Characteristics):
7568 Describe HP-UX cc bug workaround more accurately.
7569 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
7570 not unsigned long.
7571 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
7572 cross-compilers, too. This undoes some of the most recent change
7573 to this file.
7575 2002-02-05 Akim Demaille <akim@epita.fr>
7577 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
7578 to make sure they are up to date when `check' is run.
7580 2002-02-05 Akim Demaille <akim@epita.fr>
7582 * doc/autoconf.texi (Making testsuite Scripts): Document
7583 package.m4.
7585 2002-02-05 Akim Demaille <akim@epita.fr>
7587 * lib/freeze.mk: New.
7589 2002-02-05 Akim Demaille <akim@epita.fr>
7591 Implement `autom4te --freeze'.
7593 * bin/autom4te.in (&freeze): New.
7594 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
7595 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
7597 2002-02-05 Akim Demaille <akim@epita.fr>
7599 * bin/autom4te.in (&parse_args): Implement `frozen files are
7600 optional are the sum of the previous files on the command line'.
7601 Also, pass `--reload-state=' on them, so...
7602 (handle_m4): don't.
7603 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
7604 (M4sh): Rely on M4sugar.
7605 (Autotest, M4sh, M4sugar): Use frozen files.
7607 2002-01-31 Akim Demaille <akim@epita.fr>
7609 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
7610 * doc/autoconf.texi (Initializing configure): Adjust.
7612 2002-01-30 Akim Demaille <akim@epita.fr>
7614 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
7615 alphanumeric to `-' instead of `_'.
7617 2002-01-30 Akim Demaille <akim@epita.fr>
7619 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
7620 for plain code, the other for cross-compilation code. The latter
7621 is now run with GCC only.
7622 * doc/autoconf.texi (Compilers and Preprocessors): New.
7624 2002-01-30 Akim Demaille <akim@epita.fr>
7626 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
7627 values.
7628 * doc/autoconf.texi (Initializing configure): Explain how to
7629 change AC_INIT default values.
7631 2002-01-29 Akim Demaille <akim@epita.fr>
7633 * tests/torture.at (Configuring subdirectories): Use configure.in,
7634 so that aclocal 1.4 works.
7635 Reported by Alexandre Duret-Lutz and Larry Schmitt.
7637 2002-01-28 Akim Demaille <akim@epita.fr>
7639 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
7640 needs an argument.
7642 2002-01-28 Akim Demaille <akim@epita.fr>
7644 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
7645 AUTOTEST_PATH *after* it was set.
7646 Don't put `.' in the PATH: the user should be precise and `./' if
7647 needed. In addition, given that the test suite does some `cd', if
7648 `.' is in the path, the `tested programs' sections will report
7649 programs found in the test suite's directory, while during the
7650 tests (performed in their own directory), these programs are no
7651 longer visible. In other words, the results is confusing and
7652 useless.
7653 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
7655 2002-01-24 Akim Demaille <akim@epita.fr>
7657 Version 2.52g.
7659 2002-01-24 Akim Demaille <akim@epita.fr>
7661 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
7662 * doc/autoconf.texi: Finally add Akim as an author.
7664 2002-01-24 Akim Demaille <akim@epita.fr>
7666 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
7667 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
7668 Bourne. Use /bin/sh.
7669 From Andreas Buening.
7671 2002-01-24 Akim Demaille <akim@epita.fr>
7673 * config/config.guess, config/config.sub, config/texinfo.tex:
7674 Update from masters.
7676 2002-01-24 Akim Demaille <akim@epita.fr>
7678 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
7679 * config/auxdir.m4, config/cond.m4, config/depend.m4,
7680 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
7681 * config/missing.m4, config/sanity.m4, config/select.m4,
7682 * config/strip.m4: Remove, to ease sync'ing with any version of
7683 Automake.
7685 2002-01-24 Akim Demaille <akim@epita.fr>
7687 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
7688 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
7689 Reported by Geir Ove Myhr.
7691 2002-01-21 Akim Demaille <akim@epita.fr>
7693 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
7695 2002-01-21 Akim Demaille <akim@epita.fr>
7697 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
7698 message on invalid options.
7699 * bin/autom4te.in (parse_args): Don't use
7700 Autoconf::General::getopt with non valid options.
7702 2002-01-17 Jim Meyering <meyering@lucent.com>
7704 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
7705 $ac_cv_exeext so we don't use an old, invalid, cached value.
7707 2002-01-11 Akim Demaille <akim@epita.fr>
7709 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
7710 Meyering.
7711 * doc/autoconf.texi (Function Portability): Document the strnlen
7712 limitation.

7714 * lib/autoscan/functions: Adjust.
7716 2002-01-06 Akim Demaille <akim@epita.fr>
7718 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
7719 package.m4, since is really depends upon configure.ac, not
7720 configure.
7721 * doc/autoconf.texi (testsuite Scripts): Adjust.
7722 * tests/Makefile.am (package.m4): New.
7723 EXTRA_DIST it since its a source.
7725 2002-01-06 Akim Demaille <akim@epita.fr>
7727 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
7728 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
7729 and PACKAGE_BUGREPORT from here...
7730 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
7731 arguments.
7732 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
7733 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
7734 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
7735 * tests/tools.at (autoheader): Adjust.
7736 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
7738 2002-01-06 Akim Demaille <akim@epita.fr>
7740 * bin/autoscan.in (scan_file): Use `&used'.
7742 2002-01-03 Akim Demaille <akim@epita.fr>
7744 * doc/autoconf.texi (Output): Improved wording regarding use of
7745 AC_OUTPUT.
7746 From Olly Betts.
7748 2001-12-18 Kevin Ryde <user42@zip.com.au>
7750 * doc/autoconf.texi (Function Portability): Add notes on sscanf
7751 sometimes needing writable input.
7753 2001-12-17 Jim Meyering <meyering@lucent.com>
7755 * doc/autoconf.texi (New Macros): Tweak wording.
7757 2001-12-14 Akim Demaille <akim@epita.fr>
7759 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
7760 trailing files, don't apply `-rf' to files which might not be
7761 created by configure (core, core.*, and *.core), but just `rm -f'.
7762 Suggested by Jonathan Kamens.
7764 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
7766 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
7768 2001-12-14 Akim Demaille <akim@epita.fr>
7770 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
7772 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
7774 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
7775 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
7776 abs_srcdir, top_srcpath to abs_top_srcdir.
7777 (_AC_OUTPUT_FILES): Adjust.
7778 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
7779 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
7780 * tests/wrappl.in, tests/wrapsh.in: Adjust.
7782 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
7784 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
7785 C/Fortran linking on HP/UX, by extracting the Fortran library
7786 search path from the LPATH line in the $F77 -v output.
7788 2001-12-12 Kevin Ryde <user42@zip.com.au>
7790 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
7791 forbidden file descriptors table.
7793 2001-11-26 Akim Demaille <akim@epita.fr>
7795 * bin/autoscan.in (%c_keywords): Build it at top level.
7796 Map to 1 in order to simplify its uses.
7798 2001-11-26 Akim Demaille <akim@epita.fr>
7800 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
7801 Remove $filepath, useless.
7802 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
7803 variables, they are really part of the tokens.
7804 Split the input line on spaces and then look for tokens.
7805 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
7806 because of `lex$U.$(OBJEXT)'.
7807 (&scan_files): Use "@list" instead of join.
7808 * doc/Makefile.am (CLEANFILES): Add *.fns.
7810 2001-11-26 Akim Demaille <akim@epita.fr>
7812 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
7813 Remove, replaced by...
7814 * tests/wrappl.in: Be common for all the Perl executables.
7815 In particular autoscan and autoheader want -I.
7816 * configure.ac: Adjust.
7817 * lib/autoscan/headers: errno.h is portable.
7819 2001-11-26 Akim Demaille <akim@epita.fr>
7821 * bin/autoscan.in (used): New.
7822 Use it.
7824 2001-11-26 Akim Demaille <akim@epita.fr>
7826 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
7827 directives.
7828 (&scan_sh_file): Remove a duplicate pattern.
7829 (&check_configure_ac): Use long options.
7830 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
7832 2001-11-26 Akim Demaille <akim@epita.fr>
7834 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
7835 Before, having a line containing the opening of a multi line
7836 comment made the whole line be ignored.
7838 2001-11-26 Akim Demaille <akim@epita.fr>
7840 * doc/autoconf.texi (Using an Autotest Test Suite): New.
7841 (testsuite Scripts): Be one of its subsection.
7842 (Autotest Logs): New.
7844 2001-11-26 Akim Demaille <akim@epita.fr>
7846 Test groups are now run two directories deeper.
7848 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
7849 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
7850 at_top_builddir.
7851 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
7852 top_srcdir, builddir and top_builddir.
7853 Use `at_*dir' relatively to the directory containing the
7854 suite, use `*dir' when relatively to the current group dir.
7856 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
7858 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
7859 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
7860 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
7861 spelling errors.
7863 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
7865 * doc/autoconf.texi (Using System Type): Add an example of `case
7866 $host' usage so people quit using `case $target' everywhere.
7868 2001-11-22 Akim Demaille <akim@epita.fr>
7870 * doc/autoconf.texi (Installation Directory Variables): Englishoes
7871 spotted by Jim Meyering.
7873 2001-11-16 Paul Eggert <eggert@twinsun.com>
7875 This patch implements a `long double' suggestion by Oliver Kiddle.
7877 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
7878 static, to catch errors if the value isn't known at compile-time
7879 and the compiler supports dynamic arrays. Change its name from
7880 `_array_' to `test_array' to avoid potential name clashes.
7881 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
7882 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
7883 better than double. Catch a bug in GCC 2.95.2 x86.
7884 * doc/autoconf.texi (C Compiler): Document the above.
7885 * NEWS: Likewise.
7887 2001-11-13 Akim Demaille <akim@epita.fr>
7889 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
7890 hand.
7891 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
7893 2001-11-13 Akim Demaille <akim@epita.fr>
7895 * lib/autotest/general.m4 (AT_INIT): After having run the test
7896 group, go back to the initial directory, not to at_suite_dir.
7898 2001-11-13 Akim Demaille <akim@epita.fr>
7900 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
7901 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
7902 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
7903 option.
7904 (AT_CHECK_CONFIGURE): Use absolute paths.
7905 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
7906 The problem is still the old one: there is no means in M4 (that I
7907 know about) to create a defining macro, because there is no means
7908 to create `$1' etc., therefore, the defining macro ``swallows''
7909 all the arguments meant to the defined macro.
7911 2001-11-13 Akim Demaille <akim@epita.fr>
7913 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
7914 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
7915 configure.ac.
7916 * tests/aclocal.m4: Remove, as it is no longer used.
7918 2001-11-13 Akim Demaille <akim@epita.fr>
7920 * lib/autotest/general.m4: Change `tests?' into `groups?' in
7921 variable names when referring to a single test group, or to
7922 `suite' when referring to the whole test suite.
7923 `at_last_test' is removed: m4 compute at_format itself.
7924 (at_stdout, at_stder1, at_stderr): New variables.
7925 (AT_CHECK): Use them.
7927 2001-11-13 Akim Demaille <akim@epita.fr>
7929 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
7930 in PATH.
7931 Create `testsuite.dir/003/run' instead of `testsuite.003'.
7932 Do it as soon as a test fails, don't wait till the end of the test
7933 suite.
7934 Don't remove $as_me.[0-9]*, since these files no longer exist.
7936 2001-11-13 Akim Demaille <akim@epita.fr>
7938 * tests/tools.at: Use absolute paths, since we are no longer run
7939 in place.
7941 2001-11-13 Akim Demaille <akim@epita.fr>
7943 Now that tests are running in their own private dir, there is no
7944 need to list the files to remove at the end of tests groups.
7946 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
7947 (AT_data_files, at_data_files): Remove.
7948 (AT_CLEANUP, AT_DATA): Simplify.
7949 (AT_INIT): Adjust.
7950 Remove the group dir if !debug && !failed.
7951 * tests/atspecific.m4: Adjust.
7953 2001-11-13 Akim Demaille <akim@epita.fr>
7955 Start a new layout for Autotest: `testsuite' creates
7956 `testsuite.dir' in which the at-check-line etc. files are to be
7957 found, and `testsuite.dir/003' where the test group 3 is run.
7959 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
7960 at_check_line_file, at_format, at_test_normalized, at_group_dir
7961 are new variables.
7962 Create the directories.
7963 Use absolute paths for at- files.
7964 (AT_CHECK): Adjust.
7966 2001-11-11 Michael Matz <matz@kde.org>
7968 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
7969 (m4_car2): New.
7970 (m4_car): Properly quote arguments.
7972 2001-11-13 Akim Demaille <akim@epita.fr>
7974 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
7975 with stricter rules on LIBOBJS.
7977 2001-11-12 Paul Eggert <eggert@twinsun.com>
7979 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
7980 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
7981 __PROTOTYPES too.
7983 2001-11-12 Akim Demaille <akim@epita.fr>
7985 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
7987 2001-11-12 Akim Demaille <akim@epita.fr>
7989 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
7990 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
7991 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
7992 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
7993 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
7994 specify to what the macro should be defined (typically to 1).
7996 2001-11-12 Akim Demaille <akim@epita.fr>
7998 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
7999 From Jim Meyering.
8001 2001-11-12 Akim Demaille <akim@epita.fr>
8003 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
8004 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
8005 definition used by Automake where LEX is +/- "${missing} lex" and
8006 `missing' itself contains variables.
8008 2001-11-12 Akim Demaille <akim@epita.fr>
8010 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
8011 Now that M4sh pushes BODY, the comments were output at the end of
8012 the test suites.
8014 2001-11-08 Akim Demaille <akim@epita.fr>
8016 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
8017 that we can trace macros from aclocal.m4.
8018 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
8019 obsoleted, and redirect to the former anyway.
8020 Reported by Ralf Corsepius.
8022 2001-11-08 Akim Demaille <akim@epita.fr>
8024 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
8025 processed only if present.
8026 * tests/torture.at (Configuring subdirectories): Use autoreconf
8027 instead of successive calls to autoconf.
8028 Add a nonexistent subdirectory to exercise the patch above.
8029 Reported by Ralf Corsepius.
8031 2001-11-08 Kevin Ryde <user42@zip.com.au>
8033 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
8034 doesn't accept .S files.

8038 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
8039 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
8040 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
8041 * bin/autom4te.in (warn_forbidden): New.
8042 (handle_output): Use it.
8043 Read m4_pattern_forbid with messages.
8045 2001-11-05 Akim Demaille <akim@epita.fr>
8047 * bin/autom4te.in (--normalize): Remove.
8048 * lib/autom4te.in: Adjust.
8050 2001-11-05 Akim Demaille <akim@epita.fr>
8052 * tests/Makefile.am (testsuite): Rename this target as...
8053 ($(TESTSUITE)): this.
8054 From Nicolas Joly.
8056 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
8058 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
8059 the --prefix option, also remove it's argument.
8061 2001-11-05 Akim Demaille <akim@epita.fr>
8063 * doc/autoconf.texi (testsuite Invocation): Update.
8064 (Writing testsuite.at): Update.
8066 2001-11-03 Akim Demaille <akim@epita.fr>

8070 2001-11-03 Akim Demaille <akim@epita.fr>
8072 * lib/Autom4te/General.pm: (&catfile, &canonfile)
8073 (&file_name_is_absolute): New, wrappers around routines from
8074 File::Spec.
8075 Use and export them.
8076 (&find_configure_ac): Optionally take a directory where to look at.
8077 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
8078 the arguments.
8079 Default @ARGV to `.', not find_configure_ac.
8080 (&autoreconf): Argument is a directory.
8081 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
8082 * doc/autoconf.texi (autoreconf Invocation): Update.
8084 2001-11-03 Akim Demaille <akim@epita.fr>
8086 * lib/Autom4te/General.pm (@export_vars, @export_subs)
8087 (@export_forward_subs): New.
8088 Add basename, dirname, and fileparse.
8089 (@EXPORT): Adjust.
8090 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
8091 Don't look for aclocal flags if we already know aclocal is not
8092 used.
8093 Move aclocal.m4t only if it exists.
8094 Reported by Ezra Peisach.
8096 2001-11-03 Akim Demaille <akim@epita.fr>
8098 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
8099 passed on command line, defaulting to ./configure.ac if present.
8100 (&maybe_autoreconf, File::Find): Remove, unused.
8101 (&autoreconf): If autoconf is not used, don't try to trace.
8103 2001-11-02 Akim Demaille <akim@epita.fr>
8105 * configure.ac: Bump to 2.52g.
8107 2001-11-02 Akim Demaille <akim@epita.fr>
8109 Version 2.52f.
8111 2001-11-02 Akim Demaille <akim@epita.fr>
8113 * config/config.guess, config/config.sub, doc/standards.texi:
8114 * config/lispdir.m4: Update from masters.
8115 * configure.ac: Bump to 2.52f.
8117 2001-11-02 Akim Demaille <akim@epita.fr>
8119 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
8120 Don't run aclocal when aclocal.m4 is not from aclocal.
8121 From Ezra Peisach.
8122 Don't run libtoolize and gettextize if --install is not given.
8124 2001-11-01 Paul Eggert <eggert@twinsun.com>
8126 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
8127 be invoked before _AS_LINENO_PREPARE.
8128 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
8129 than character ranges.
8131 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
8132 invoking AS_BASENAME. Set the locale variables to 'C' if
8133 possible, as POSIX requires this to get the traditional
8134 behavior.
8135 * doc/autoconf.texi (Special Shell Variables): Describe the above.
8137 2001-10-31 Paul Eggert <eggert@twinsun.com>
8139 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
8140 with {}, as that triggers a bug in Bash 2.05.
8142 (_AS_LINENO_PREPARE): Use Sed rather than
8143 Awk. Fix the sed prepass to work even if there are multiple
8144 instances of $LINENO on the same line. Do not substitute for
8145 other variables like $LINENOT. Do not check file dates; such a
8146 check is unreliable on sufficiently fast machines, and removing
8147 the check makes the code simpler and more reliable. Check for
8148 output and chmod failures.
8150 * doc/autoconf.texi (Special Shell Variables): Document
8151 the above.
8153 2001-10-31 Akim Demaille <akim@epita.fr>
8155 * tests/Makefile.am (atconfig): Remove this target, Automake
8156 handles it now.
8158 2001-10-31 Akim Demaille <akim@epita.fr>
8160 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
8161 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
8162 provided, while it is optional.
8163 * configure.ac: Adjust.
8165 2001-10-26 Paul Eggert <eggert@twinsun.com>
8167 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
8168 lib/Autom4te/Struct.pm:
8169 Require Perl 5.005_03 instead of just 5.005, as some tests fail
8170 with 5.005_02.
8172 * doc/autoconf.texi (Special Shell Variables): Document some
8173 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
8175 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
8176 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
8177 eval $LINENO is not portable in practice.
8179 2001-10-24 Akim Demaille <akim@epita.fr>
8181 * lib/Autom4te/General.pm (backname): New.
8183 2001-10-24 Akim Demaille <akim@epita.fr>
8185 * m4/: Remove, merged into...
8186 * config/: here.
8188 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
8190 * doc/autoconf.texi (Shellology): Mention the problems with bash
8191 2.05's use of ANSI quoting in its `set' builtin.
8193 2001-10-22 Paul Eggert <eggert@twinsun.com>
8195 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
8196 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
8197 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
8198 POSIX decided to standardize on the int flavor of strerror_r.
8199 Always do char* test, as there's no reason not to.
8200 Assign to a char* var, to catch strerror_r that returns int*.
8202 * doc/autoconf.texi (Particular Functions):
8203 Document the above changes. Also, document the fact that
8204 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
8206 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
8208 2001-10-20 Akim Demaille <akim@epita.fr>
8210 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
8211 the executable was missing from the log.
8213 2001-10-20 Akim Demaille <akim@epita.fr>
8215 * lib/Autom4te/General.pm (&update_file): If destination is
8216 unchanged, remove the source.
8217 (&up_to_date_p): Don't be verbose, be debug.
8218 * bin/autoreconf.in: No longer support --m4dir.
8219 (&autoreconf): Display the full path of the configure.ac we are
8220 studying.
8221 Trace it only once.
8222 Be sure to honor --force with gettextize.
8223 Always run aclocal.
8224 * doc/autoconf.texi: Adjust.
8226 2001-10-20 Akim Demaille <akim@epita.fr>
8228 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
8229 Remove, dead.
8230 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
8231 `intl' is already present, as it refuses unless --force.
8232 (&parse_args): Use -I, --include instead of the old Autoconf
8233 options.
8234 ($localdir, $autoconf_dir): Remove.
8235 (@include): New.
8236 (&maybe_autoreconf): New, to preserve $_ for File::Find.
8238 2001-10-19 Jens Petersen <petersen@redhat.com>
8240 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.

8250 2001-10-19 Akim Demaille <akim@epita.fr>
8252 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
8253 comment, explain how to install automatic mode selection.
8254 From Russ Allbery.
8256 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
8258 * bin/autoreconf.in (autoreconf): Display the path to the
8259 configure.ac being studied.
8261 2001-10-18 Paul Eggert <eggert@twinsun.com>
8263 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
8264 long, to work around a bug in the HP C compiler version HP92453-01
8265 B.11.11.23709.GP.
8267 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
8268 (AS_BASENAME_EXPR): New macro.
8269 (AS_BASENAME_SED): Do not assume GNU sed semantics.
8270 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
8271 and fall back on 'sed' only if the other two fail. This makes
8272 AS_BASENAME act more like AS_DIRNAME.
8273 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
8274 contains white space.
8275 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
8276 Use AS_DIRNAME, since I think it's now DOS-friendly.
8277 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
8278 Allow "dirname //FOO" to return either / or //, as POSIX allows
8279 either behavior.
8281 2001-10-10 Akim Demaille <akim@epita.fr>
8283 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
8284 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
8285 From Eric Sharkey.

8289 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not

8334 * bin/autoreconf.in: Rewrite in Perl.
8335 * configure.ac: Adjust.

8403 (AT_INIT): Replace AC_PLAIN_SCRIPT with AS_INIT invocation,
8404 include handle the m4_pattern_*, no longer push the

8417 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): If the current
8418 shell does not support LINENO, and if CONFIG_SHELL is unset or
8419 empty, and if we can find a shell that does support LINENO,
8420 then set CONFIG_SHELL to that shell and then re-execute
8421 ourselves with CONFIG_SHELL.
8423 2001-10-05 Paul Eggert <eggert@twinsun.com>
8425 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
8426 doesn't exist. Remove *.tmp, as a .tmp file is created during the
8427 build of $(TESTSUITE).
8429 2001-10-05 Akim Demaille <akim@epita.fr>
8431 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

8468 compatibility with POSIX shells.

8472 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
8473 instead of exec'ing to preserve $0 and $@.
8475 2001-10-01 Akim Demaille <akim@epita.fr>
8477 * tests/testsuite (AT_INIT) <at_pass_list>: New.

8496 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
8497 Don't use nested parenthesization. This patch was originally
8498 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
8499 but somehow it didn't get incorporated then.
8500 * doc/autoconf.texi (Limitations of Usual Tools):
8501 Clarify remark about sed and nested parenthesization.
8503 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
8504 Report an error if the size cannot be determined even though
8505 the type exists.
8506 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8507 Check for `expr' arithmetic overflow, and for compilation failure,
8508 and invoke a new argument $4 if either is discovered.
8509 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
8510 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
8512 2001-09-28 Akim Demaille <akim@epita.fr>

8532 status when executing the ACTION-IF-FALSE.
8533 * tests/base.at (AC_TRY_*): Rename as...

8540 * tests/c.at (Extensions, C keywords)
8541 (Broken/missing compilers, AC_PROG_CPP with warnings)
8542 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
8543 (AC_PROG_CPP requires AC_PROG_CC): here and...
8544 * tests/fortran.at (GNU Fortran 77): there.
8545 * doc/autoconf.texi (autoconf Invocation): Fix the example:
8546 AC_TRY_RUN is about compilation, not shell commands.
8547 (Test Programs): AC_TRY_RUN works as used to be advertised.
8549 2001-09-27 Akim Demaille <akim@epita.fr>
8551 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
8552 Raja R Harinath:
8553 Be sure to detect when $LINENO always returns the same value.
8554 Look for the original script, basename($0) is certainly not
8555 enough.
8556 Pass the CLI arguments to `$as_me.lineno'.
8558 2001-09-25 Akim Demaille <akim@epita.fr>
8560 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.
8561 Be sure the close and reopen the LOG fd before and after using tee

8565 2001-09-23 Akim Demaille <akim@epita.fr>
8567 * bin/autom4te.in (parse_args): There can be several invocations
8568 of --language now.
8570 2001-09-23 Akim Demaille <akim@epita.fr>
8572 * doc/autoconf.texi (Top): Wrap in @ifnottex.
8574 2001-09-23 Akim Demaille <akim@epita.fr>
8576 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
8577 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.

8579 builddir, buildpath, top_builddir, and top_buildpath.
8580 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
8581 the current directory.

8586 variables.
8588 * lib/autotest/general.m4: Do not reset AT_victims.
8589 Don't compute at_srcdir nor at_top_srcdir.
8591 * tests/tools.at: Hence use top_srcdir.
8593 * tests/Makefile.am, tests/autoconf, tests/autoheader,
8594 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:

8606 * doc/autoconf.texi (Common Shell Constructs): Rename as...

8641 to match current versions from CVS Automake.
8643 2001-09-23 Alexandre Duret-Lutz <duret_g@epita.fr>

8648 2001-09-22 Akim Demaille <akim@epita.fr>
8650 * lib/autoconf/autotest.m4: Create `package.m4'.
8651 * tests/Makefile.am (package.m4): Remove.
8653 2001-09-22 Akim Demaille <akim@epita.fr>

8658 `$LINENO' support replacement when not supported.
8659 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
8660 them explicitly to be sure they are not output before this section
8661 (via m4_require). Cosmetic only.

8663 * lib/autoconf/programs.m4: Replace all the occurrences of
8664 `__oline__' with `$LINENO'.
8665 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
8667 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>

8670 character (u: -> ue) in a code comment.
8671 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
8672 it works.
8674 2001-09-21 Akim Demaille <akim@epita.fr>
8676 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
8677 Suggested by Jim Meyering.
8679 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8681 * lib/autoconf/programs.m4: Use extensions listed in

8694 PATH_SEPARATOR.
8695 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
8696 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
8697 be used instead of ':'.
8698 * lib/autotest/general.m4: Replace occurrences of ':' in
8699 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
8701 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

8704 arguments. Fixed a typo.
8706 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8708 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
8709 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
8711 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8713 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.

8720 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
8722 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
8723 already have $file). Set output files to binary mode (helps avoid
8724 CR issues on DOSish systems).
8726 2001-09-19 Akim Demaille <akim@epita.fr>
8728 * lib/autotest/general.m4: Englishoes.
8729 From Tim Van Holder and Alexey Mahotkin.
8731 2001-09-18 Paul Eggert <eggert@twinsun.com>
8733 * doc/autoconf.texi (Common Shell Constructs): New node,
8734 documenting AS_DIRNAME.
8735 (Limitations of Usual Tools): Refer to it when discussing dirname.
8736 Also, update discussion of POSIX standard to reflect latest draft.
8738 * lib/autoconf/c.m4:
8739 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
8741 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
8742 Do not pass a first argument with leading '-'
8743 to expr, by parenthesizing initial integers that might be negative.
8745 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
8746 now merely checks whether it is an error to pass an argument
8747 to getpgrp.
8749 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
8750 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
8751 whether it is a (compile-time) error to pass an argument to
8752 getpgrp. This simpler test supports the revised documentation,
8753 and is all that AC_FUNC_GETPGRP's users really need.
8755 2001-09-18 Akim Demaille <akim@epita.fr>
8757 * doc/autoconf.texi (Limitations of Make) <$<>: New.
8759 2001-09-18 Akim Demaille <akim@epita.fr>

8765 2001-09-18 Paul Wagland <paul@wagland.net>
8767 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
8768 correctly.
8769 Add test for AS_BASENAME.
8770 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
8771 added test. It now correctly handles /1/2/3/, returning '3' not ''.
8772 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
8773 * tests/base.at: Fixed the expected responses. The old ones were
8774 one line out...
8775 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
8776 the documentation claims it should (and how it behaved in 2.13).
8778 2001-09-18 Akim Demaille <akim@epita.fr>
8780 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
8781 the AC_CONFIG_COMMANDS invocation.
8782 This also solves the name clash problems.
8783 Don't set the package's ID.
8784 * lib/m4sugar/Makefile.am (version.m4): Revamp.
8785 No longer to be shipped.
8786 (version.in): Remove.
8787 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
8788 * lib/autoconf/status.m4: Adjust.
8789 Use `m4_PACKAGE_STRING'.
8790 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
8791 the only optional argument is the name of the test suite.
8792 Expect `package.m4' to define the package signature.
8793 * lib/autom4te.in (Autotest): Add `package.m4?'.
8794 * tests/Makefile.am (package.m4): New.
8795 * tests/suite.at: ifnames is a victim.
8797 2001-09-18 Akim Demaille <akim@epita.fr>
8799 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
8800 AC_LIBSOURCE, AC_CONFIG_FILES.
8801 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
8802 program version string doesn't match the package's.
8803 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
8804 after `(cached)'.
8806 2001-09-17 Paul Eggert <eggert@twinsun.com>
8808 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8809 Allow expression to return any value that can fit into unsigned long
8810 (not int, as before). Check for output errors.
8812 2001-09-17 Bruno Haible <haible@ilog.fr>
8814 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
8815 Always include <stdio.h> and <stdlib.h>. Evaluate
8816 the expression in an extra function before these includes. Call
8817 fprintf "%d" only after ensuring the argument is of type 'int'.
8818 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
8820 2001-09-17 Paul Eggert <eggert@twinsun.com>
8822 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
8823 or CFLAGS=-O5. In that case, the linker has a relaxed view of
8824 fatal errors, and AC_CHECK_LIB causes it to include libraries even
8825 when they don't exist.
8827 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
8828 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
8829 need it.
8831 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
8832 version with the version used by fileutils 4.1, except use
8833 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
8834 we don't need it.
8836 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
8838 2001-09-13 Akim Demaille <akim@epita.fr>
8840 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
8841 _first_.
8842 Reported by Gerrit P. Haase.
8844 2001-09-13 Akim Demaille <akim@epita.fr>
8846 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that

8862 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
8863 Likewise.
8864 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
8865 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
8866 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
8867 AT_tests_all for consistency.
8868 Set at_victims.
8869 (AT_VICTIMS): Similar to AT_KEYWORDS.
8870 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
8872 2001-09-13 Akim Demaille <akim@epita.fr>
8874 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
8876 2001-09-13 Akim Demaille <akim@epita.fr>
8878 * lib/autotest/general.m4 (AT_INIT): Create and remove
8879 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
8880 test suites can cohabit.
8882 2001-09-13 Akim Demaille <akim@epita.fr>
8884 * tests/mktests.sh: Don't output banners for empty test files.
8886 2001-09-13 Akim Demaille <akim@epita.fr>
8888 Test suites can be run independently of configure.
8890 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
8891 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.

8906 * tests/ifnames: New.
8908 2001-09-13 Akim Demaille <akim@epita.fr>
8910 * lib/autotest/general.m4 (AT_INIT): Let --keywords also match
8911 test group titles.
8912 * tests/atspecific.m4 (AT_CHECK_AU_MACRO): AT_KEYWORDS(autoupdate).

8932 Spread a few keywords in the Autoconf test suite.
8934 2001-09-10 Akim Demaille <akim@epita.fr>
8936 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't pass
8937 PATH_SEPARATOR, let M4sh compute it.
8938 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): New.

8947 * lib/autotest/general.m4 (AT_INIT): Use _AS_PATH_WALK to
8948 normalize the path, and to look for victims.
8949 * tests/semantics.at (AC_PATH_PROG & AC_PATH_PROGS)
8950 (AC_CHECK_PROG & AC_CHECK_PROGS): Use PATH_SEPARATOR.
8952 2001-09-07 Akim Demaille <akim@epita.fr>
8954 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
8955 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
8956 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
8957 related variables into `at_package_*'.
8958 * lib/autotest/general.m4 (AT_VICTIMS): New.
8959 (AT_INIT): Adjust for stand-alone/embedded test suites.
8960 (AS_MESSAGE_LOG_FD): Define and use it.

8965 2001-09-07 Akim Demaille <akim@epita.fr>
8967 Move toward possibly stand-alone test suites.
8969 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,
8970 in addition, it introduces useless differences in logs.
8971 (AT_INIT): Let atconfig and atlocal be both optional.
8972 Adjust PATH computation.
8973 * lib/m4sugar/m4sh.m4 (AS_UNAME): More readable display of PATH.

8982 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Use `_array_'
8983 to avoid GCC warnings.
8984 From Uwe Seimet.
8986 2001-09-05 Akim Demaille <akim@epita.fr>
8988 * bin/autom4te.in: --language is -l, not -s.
8990 2001-09-05 Akim Demaille <akim@epita.fr>
8992 Be ready to handle filenames as stupid as `dnl.at', for if even
8993 the maintainer is dumb enough to do that...
8995 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
8996 excellence in M4 quotation: consider `__file__' is active.
8998 And BTW, when invoking m4, pass the --include in the right order:
8999 the wrong one.
9001 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
9002 4m.
9004 2001-09-05 Akim Demaille <akim@epita.fr>
9006 * lib/Autom4te/XFile.pm: New lib file.
9007 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
9008 * bin/autoheader.in: Use it.
9010 2001-09-05 Akim Demaille <akim@epita.fr>
9012 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

9020 * bin/autoscan.in: Use `getopt' and `find_files' etc.
9021 Add -I, --include support.
9022 * doc/autoconf.texi (autoscan Invocation): Adjust.
9024 2001-09-05 Akim Demaille <akim@epita.fr>
9026 CVS GNU M4 doesn't like `undefine(undefined)'.
9028 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
9029 New, extracted from main.
9030 Use IO::File wherever possible.
9031 (input.m4): Be constant, use -I instead of hard coding $tmp.
9032 Therefore be a quoted heredoc.
9033 Don't invoke `_au_disable', since ac was not loaded, but just
9034 `unm4.m4'.
9036 2001-08-31 Akim Demaille <akim@epita.fr>
9038 Version 2.52d.
9040 2001-08-31 Akim Demaille <akim@epita.fr>

9043 previous patch.

9046 2001-08-31 Akim Demaille <akim@epita.fr>
9048 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): DU 5.0 has
9049 serious problems handling heredocs in heredocs.
9050 Reported by Nicolas Joly.
9052 2001-08-31 Akim Demaille <akim@epita.fr>
9054 * doc/autoconf.texi: Don't promote non `m4_*' M4 macros.
9055 (Making testsuite Scripts): Update.
9057 2001-08-31 Akim Demaille <akim@epita.fr>
9059 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
9061 2001-08-31 Akim Demaille <akim@epita.fr>
9063 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
9064 (testsuite Scripts): There is no such thing as `atconfig.in'.
9065 And actually one diagram is missing: test suite runtime.
9067 2001-08-31 Akim Demaille <akim@epita.fr>
9069 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
9070 inverse order.
9072 2001-08-31 Akim Demaille <akim@epita.fr>
9074 * bin/autoupdate.in (@include): `installcheck' revealed the path
9075 to m4sugar was lacking!
9077 2001-08-31 Akim Demaille <akim@epita.fr>
9079 * man/Makefile.am (.x.1): We really have to pass
9080 autom4te_perllibdir.
9082 2001-08-31 Akim Demaille <akim@epita.fr>
9084 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
9085 debug scripts, in particular passing explicitly listed tests to
9086 run is stupid.
9088 2001-08-31 Akim Demaille <akim@epita.fr>
9090 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
9091 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
9092 Use directly autom4te, not autoconf.
9093 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
9095 2001-08-31 Akim Demaille <akim@epita.fr>
9097 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
9098 * bin/autoheader.in (%symbol): Strip arguments of macros.

9104 2001-08-31 Akim Demaille <akim@epita.fr>
9106 * bin/autom4te.in (&parse_args): Die on unknown languages.
9107 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
9108 need for autoconf.
9109 Promote --include over --macrodir and other obsolete options.
9111 2001-08-31 Akim Demaille <akim@epita.fr>
9113 * lib/Autom4te/General.pm ($version, $help, &getopt): New.
9114 * bin/autoupdate.in, bin/autoheader.in, bin/autom4te.in: Use them.
9115 * bin/autom4te.in ($autoconf): Pass --force.
9116 `print $out' doesn't print `$_' but `$out'.
9117 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
9118 (autoheader): Pass --force since the test suite goes too fast for
9119 the time stamps.
9120 Adjust to the new autoheader messages.
9122 2001-08-31 Akim Demaille <akim@epita.fr>
9124 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
9125 Check the completeness of the #template.

9127 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER
9128 invocation.
9130 2001-08-31 Akim Demaille <akim@epita.fr>
9132 * lib/Autom4te/General.pm (&find_file, &update_file): New.
9133 * bin/autoupdate.in, bin/autoheader.in: Adjust.
9134 Drop AC_MACRODIR dead for real.
9135 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
9136 `autoheader: `config.hin' is created'.
9137 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
9139 2001-08-31 Akim Demaille <akim@epita.fr>
9141 * bin/autoheader.in: Rewrite in Perl.
9142 * tests/autoheader: Adjust.
9144 2001-08-31 Akim Demaille <akim@epita.fr>
9146 * bin/autoconf.in (--include, -I): New option.
9147 Map --localdir, --autoconf-dir onto it.
9148 Forward autom4te's options instead of interpreting them.
9149 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
9150 There is no such envvar since the inception of autom4te.cfg.
9151 * bin/autom4te.in (&parse_args): Uniquify `@include'.
9152 * bin/autoupdate.in: Adjust, and perform more control.
9153 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
9154 * tests/autoconf: Dittowise.
9156 2001-08-31 Akim Demaille <akim@epita.fr>
9158 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
9159 * bin/autom4te.in (&find_file): Support `FILE?' standing for
9160 optionally `FILE'.
9161 Use -e, not -f, since /dev/null for instance is OK.
9162 (&parse_args): Adjust.
9163 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
9165 2001-08-31 Akim Demaille <akim@epita.fr>
9167 * configure.ac: Also find tested executables in bin.
9168 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
9169 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
9170 installed peer executables, only PATH is allowed to resolve it.
9171 Pass `autoconf_dir' via options, not via invisible envvars.
9172 * lib/Autom4te/General.pm (&find_peer): Remove.
9173 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
9174 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
9175 * man/Makefile.am: Let help2man rely on PATH instead of trying to
9176 find the executables for it.
9177 * tests/Makefile.am: Major cleanup. Too lazy to document...
9178 * tests/atlocal.in: Remove all the obscure envvar manipulations.
9179 We only need PERL.
9180 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
9181 indeed related to running the test suite, while passing
9182 --autoconf-dir and others is related to running non installed
9183 Autoconf executables. So don't do that, leave it to...
9184 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
9185 * tests/autoscan: New.
9186 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
9187 refer to library files: rely on --language.
9189 2001-08-29 Akim Demaille <akim@epita.fr>
9191 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
9192 s/--set/--language/.
9194 2001-08-29 Akim Demaille <akim@epita.fr>
9196 * doc/autoconf.texi: Strip the @nodes.
9197 Suggested by Paul Eggert.

9200 2001-08-29 Akim Demaille <akim@epita.fr>
9202 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
9203 Suggested by Paul Eggert.
9205 2001-08-29 Akim Demaille <akim@epita.fr>
9207 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
9208 download in a tmp dir.
9210 2001-08-29 Akim Demaille <akim@epita.fr>
9212 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are
9213 case insensitive OSes out there :(
9214 From Tim Van Holder.
9216 2001-08-29 Akim Demaille <akim@epita.fr>
9218 * lib/autom4te.in: New.
9219 * lib/Makefile.am (edit, autom4te.cfg): New.
9220 * bin/autom4te.in (BEGIN): Simplify.
9221 Rely on `AC_MACRODIR' in addition of `autom4te_perllibdir'.

9223 (&parse_args): Support --mode, --set, and --melt.
9224 * bin/autoconf.in: Simplify and adjust.
9225 * tests/Makefile.am (AUTOMAKE): Use --set.
9226 * tests/atlocal.in: Adjust.
9227 * BUGS: distcheck and check are weak.
9229 2001-08-29 Akim Demaille <akim@epita.fr>
9231 * lib/autotest/general.m4: Use
9232 foo=`(command) 2>/dev/null`
9233 not
9234 foo=`command` 2>/dev/null
9235 (at-devnull): Rename as...
9236 (AT-devnull): this.
9237 (--clean): Remove AT-* files too.
9238 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
9239 Reported by Nicolas Joly.
9241 2001-08-28 Akim Demaille <akim@epita.fr>
9243 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't use single

9251 2001-08-27 Tim Van Holder <tim.van.holder@pandora.be>
9253 * lib/autotest/general.m4: Reword some messages.
9254 (AT_INIT): Check for the `times' builtin before using it.
9255 Support test ranges as arguments to the testsuite.
9256 Have -e imply -d as the help text suggested.
9258 2001-08-27 Akim Demaille <akim@epita.fr>
9260 * Makefile.maint: Formatting changes.
9261 (do-po-update, po-update, cvs-update, update): New targets.

9268 Pass it to debug-*.sh scripts.
9269 <AUTOTEST_PATH>: May contain absolute dir names.
9271 2001-08-27 Akim Demaille <akim@epita.fr>
9273 * lib/autotest/general.m4 (AT_INIT): Log the command line.
9274 Support `VAR=VAL' as arguments.
9275 Compute PATH _after_ the options processing, so that AUTOTEST_PATH
9276 may be set via the command line.
9278 2001-08-27 Akim Demaille <akim@epita.fr>
9280 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): $2 defaults to $1.

9282 first the build dirs, then the src dirs.

9292 2001-08-27 Akim Demaille <akim@epita.fr>
9294 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
9295 `ac_top_builddir' to mimic Automake's vocabulary, which much more
9296 readable.
9297 Adjust callers.
9298 * doc/autoconf.texi (Configuration Actions): Document the vars
9299 available in commands.
9300 Emphasize the risks of collisions in init-cmds.

9304 * doc/autoconf.texi (Input) <AC_INIT>: Move to..
9305 (Initializing configure): this new node.
9307 2001-08-27 Akim Demaille <akim@epita.fr>

9330 * lib/autoconf/status.m4 (_AC_SRCPATHS): New.
9331 (_AC_OUTPUT_LINKS, _AC_OUTPUT_FILES, _AC_OUTPUT_SUBDIRS): Use it.
9332 Standardize the var names (ac_sub_srcdir -> ac_srcdir, ac_subdir
9333 -> ac_dir).
9334 (_AC_OUTPUT_HEADERS): AS_DIRNAME always return a dir name.
9335 * lib/autoconf/general.m4 (_AC_INIT_HELP): Ditto.

9362 * Makefile.am (AUTOMAKE_OPTIONS): Add 1.5 and dist-bzip2.
9363 (AMTAR): Help automake define it.
9364 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
9365 needed, 1.5 can have a macro and a target with the same name.
9366 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
9367 * m4/strip.m4: New.

9382 * bin/autoupdate.in: Distinguish M4sugar vs. Autoconf macros by
9383 the name of the directory they're in, instead of the filename,
9384 since version.m4 is now in m4sugar, but m4_acversion must not be
9385 classified as an Autoconf macro.
9386 ($input_m4): Don't qualify the path to m4sugar.
9387 Rather, pass autoconf_dir to m4.
9388 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

9466 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Prepare the cross-compile
9467 program with AC_LANG_PROGRAM before feeding it to
9468 AC_COMPILE_IFELSE. Cleanup grep usage.
9470 2001-08-20 Akim Demaille <akim@epita.fr>
9472 * ChangeLog, ChangeLog.0, ChangeLog.1, ChangeLog.2, AUTHORS, BUGS,
9473 * NEWS, README, README-alpha, TODO, tests/README: This package is
9474 `Autoconf', not `autoconf' (the executable).
9476 2001-08-20 Akim Demaille <akim@epita.fr>
9478 Info readers seem to need `Index' in the index node title :(
9480 * doc/autoconf.texi: Reverse the 2001-08-15 change which
9481 simplified index node names.
9483 2001-08-20 Akim Demaille <akim@epita.fr>
9485 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Warn if the
9486 arguments are not literals.

9525 2001-08-20 Akim Demaille <akim@epita.fr>
9527 Huh!?!?! There are still some user EOF tags used, which prevents
9528 their use in AC_CONFIG_COMMANDS for instance...
9530 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
9531 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',
9532 `_CSEOF', or `_ATEOF', as appropriate.
9533 * lib/m4sugar/Makefile.am, lib/autoconf/Makefile.am,

9538 * tests/base.at, tests/m4sh.at, tests/m4sugar.at,
9539 * tests/semantics.at, tests/tools.at, tests/torture.at:
9540 s/^AT_DATA\(([^][]+),/AT_DATA([$1],/.

9544 Autotest invokes M4sh's initialization.

9592 2001-08-17 Akim Demaille <akim@epita.fr>
9594 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not
9595 `$0.log' as for projects where testsuite is in src, we'd have
9596 testsuite.log created in src.
9598 2001-08-17 Akim Demaille <akim@epita.fr>
9600 * bin/autom4te.in (&parse_args): Recognize --normalize.

9610 2001-08-17 Akim Demaille <akim@epita.fr>
9612 * doc/autoconf.texi: Work around Texinfo buglets.
9613 (Transformation Rules): One example is enough, users are expected
9614 to have their brains on. And BTW, use DESTDIR.
9615 (dvar): New macro. Use it.
9617 2001-08-17 Akim Demaille <akim@epita.fr>
9619 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.
9620 * lib/autotest/general.m4 (AT_INIT): Use the relative dir when

9626 * bin/autoconf.in: Use it.

9636 start, not at end.
9638 2001-08-15 Akim Demaille <akim@epita.fr>

9651 (Autoconf Macros, M4 Macros, Autotest Macros): these.
9652 * doc/install.texi: Use @command.
9653 (Environment Variables): Rename as...
9654 (Defining Variables): this.
9656 2001-08-15 Akim Demaille <akim@epita.fr>
9658 * doc/autoconf.texi (Function Portability): sprintf's return
9659 value.
9660 From Kevin Ryde.
9662 2001-08-15 Akim Demaille <akim@epita.fr>
9664 * Makefile.maint (CVS): New.
9665 (local-check): Run changelog-check. last.
9666 (alpha): Don't depend upon local-check, since...
9667 (cvs-dist): depends upon it.
9669 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
9671 * tests/Makefile.am: Use a clean-local rule to remove
9672 autom4te.cache (it's a directory, not a file.
9673 * Makefile.am: Ditto (but maintainer-clean-local).
9675 2001-08-15 Akim Demaille <akim@epita.fr>
9677 * bin/autom4te.in (@m4_warning): New.
9678 (&handle_m4): Use it.
9679 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the
9680 warnings are issued at each run.
9681 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): M4sugar
9682 is in the src tree.
9684 2001-08-15 Akim Demaille <akim@epita.fr>
9686 * tests/atspecific.m4 (AT_CHECK_AUTOUPDATE): Perl is now required:
9687 don't waste time running `autoupdate --version' works.
9688 * tests/tools.at (autoupdating AC_PREREQ): Likewise.
9690 2001-08-13 Akim Demaille <akim@epita.fr>
9692 * doc/autoconf.texi (ma): Rename this index as...

9711 endianness for comparison instead of relying on AT_CHECK_ENV.
9713 2001-08-11 Paul Eggert <eggert@twinsun.com>

9743 * tests/mktests.sh: Update year in copyright notice.
9745 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
9747 * tests/semantics.at (AC_C_BIGENDIAN): New test.
9749 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9751 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
9752 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
9753 * doc/autoconf.texi (C Compiler Characteristics): Update
9754 documentation for AC_C_BIGENDIAN.
9756 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
9758 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
9759 magic values from an object file when cross-compiling.
9760 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
9762 2001-08-10 Akim Demaille <akim@epita.fr>
9764 * bin/autom4te.in (&handle_output): Don't use `grep' with side
9765 effects.
9766 Suggested by Russ Allbery.
9768 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
9770 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
9771 current $prefix to the sub-configures.
9773 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
9775 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
9776 extension (needed on BeOS). Reported by Guido van Rossum.
9778 2001-08-09 Akim Demaille <akim@epita.fr>
9780 * bin/autom4te.in ($icache): Load it only if older than autom4te.
9782 2001-08-07 Akim Demaille <akim@epita.fr>
9784 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
9785 removed.
9786 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
9787 No need to remove the files before and after the each test, before
9788 each test and at the end of the suite is enough.
9789 Display only the children `times', not the shell's.
9790 If the test failed or was skipped, at-times is not available.
9792 2001-08-07 Akim Demaille <akim@epita.fr>
9794 Always produce testsuite.log, including when there are no
9795 failures. This helps getting information on skipped tests, and
9796 duration of the tests. Err, implement the latter btw.
9798 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
9799 Dump information on the first run of each test.
9800 (AT_CLEANUP): Create `at-times' containing the duration of the
9801 test group.
9803 2001-08-07 Akim Demaille <akim@epita.fr>
9805 The use of `dumpstat' revealed that `len' was used although it
9806 should not. m4_text_wrap was using it, but in the Autoconf world
9807 where it is legal. Hence (i) test M4sh in its own world, not
9808 Autoconf's, and (ii), ahem, fix the bug :)
9810 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
9811 does not like `' instead of [].
9812 (AT_INIT): Forbid `^_?AT_'.
9813 And don't output such tokens.
9814 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
9815 `script.as', and `autom4te.cache'.
9816 Remove `empty' and `macro' which are no longer used.
9817 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
9818 * tests/m4sugar.at: Use it.
9819 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
9821 2001-08-07 Akim Demaille <akim@epita.fr>
9823 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
9825 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
9827 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
9829 2001-08-04 Akim Demaille <akim@epita.fr>
9831 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
9832 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
9833 AC_TRY_LINK.
9834 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
9835 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
9836 (AC_F77_MAIN): Likewise.
9838 2001-08-04 Akim Demaille <akim@epita.fr>
9840 Don't rely on M4sugar outputting the patterns in files, since we
9841 might process the output _without_ running m4, hence without these
9842 files.
9844 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
9845 * bin/autom4te.in (@Request::includes): Remove, unused.
9846 (@Request::source): Rename as...
9847 (@Request::input): this.
9848 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
9849 (&handle_output): Fetch the patterns from the traces.
9850 `$forbidden' and `$allowed' are constant: use m//o.
9851 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
9852 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
9854 2001-08-04 Akim Demaille <akim@epita.fr>
9856 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
9857 autoconf', i.e., in addition to caching traces, cache the output.
9859 * bin/autom4te.in (Request::cache): Rename as...
9860 (Request::id): this.
9861 ($cache, $icache, $tcache, $ocache): New.
9862 (&handle_m4): Save M4 output in the cache instead of $tmp.
9863 (&handle_output): Adjust.
9864 (&up_to_date_p): Check that the output cache is up to date too.
9865 (top level): Run `&handle_m4' iff force or the cache is invalid.
9866 Run `&handle_output' if the output cache is more recent.
9868 2001-08-04 Akim Demaille <akim@epita.fr>
9870 * bin/autom4te.in ($force): New.
9871 (&parse_args, &print_usage): -f, --force is a new option.
