1 2007-01-28 Paul Eggert <eggert@cs.ucla.edu>
3 * doc/autoconf.texi (Shellology): pdksh 5.2.14 is still the
4 latest version.
5 (Shell Substitutions): Note problems with @{var:=value} etc.
6 Add a new section for problems with @{#var} etc. Problem noted
7 by Ralf Wildenhues. See:
8 http://lists.gnu.org/archive/html/libtool-patches/2005-01/msg00157.html
10 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
12 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
13 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
14 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
15 substitution will still be done by the special code.
16 Report by Jim Meyering.
18 * doc/autoconf.texi (File System Conventions): Mention that
19 $PATH_SEPARATOR is for the build system only.
20 Report by Keith Marshall.
22 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
24 * doc/autoconf.texi (Setting Output Variables): Mention that
25 all non-NUL characters are ok in substituted values.
26 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
27 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
28 carriage return for $AWK, needed for BSD awk.
29 * tests/torture.at (Substitute and define special characters):
30 Test all 8 bit non-NUL characters.
31 Report against Automake by Patrick Welche.
33 2007-01-15 Stepan Kasal <kasal@ucw.cz>
35 * doc/autoconf.texi (Specifying Names): `--host' does not
36 change the build type.
38 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
40 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
41 early on the reader side, drop stderr of the input to avoid
42 `broken pipe' error output; this may happen even with shell
43 builtin `echo' of some bash versions. Reports by Ian Macdonald
44 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
46 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
48 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
49 separate items of `ac_user_opts', to avoid long lines.
50 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
52 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
54 * doc/autoconf.texi: Fix some typos.
56 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
58 Fix some wording problems noted by Paolo Bonzini in:
59 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
60 * doc/autoconf.texi (Signed Overflow Examples): Give more
61 discussion about the allow_superuser_privileges example,
62 and change it a bit to make things clearer.
63 (Optimization and Wraparound): Clarify whether the compiler
64 will generate an infinite loop for the example derived from
65 Autoconf's mktime test.
66 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
67 Also, clarify unsigned multiplication overflow.
69 2007-01-04 Eric Blake <ebb9@byu.net>
71 * bin/Makefile.am (RELEASE_YEAR): New macro.
72 (edit): Use it to supply correct copyright year to scripts.
73 * bin/autoconf.as (version): Use it.
74 * bin/autoheader.in ($version): Likewise.
75 * bin/autom4te.in ($version): Likewise.
76 * bin/autoreconf.in ($version): Likewise.
77 * bin/autoscan.in ($version): Likewise.
78 * bin/autoupdate.in ($version): Likewise.
79 * bin/ifnames.in ($version): Likewise.
81 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
83 * doc/autoconf.texi (Integer Overflow): Revised based on today's
84 feedback. The most important changes document what happens when
85 you convert an out-of-range value to a signed integer type, and
86 say that (sum < a) != (b < 0) reliably detects overflow when sum =
87 a + b.
89 * doc/autoconf.texi (Integer Overflow): Greatly expand and
90 rewrite, taking notions from the recent discussion on the gcc and
91 autoconf mailing lists; please see
92 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
93 and follow the many links.
94 (Integer Overflow Basics, Signed Overflow Examples):
95 (Optimization and Wraparound, Signed Overflow Advice):
96 (Signed Integer Division): New sections.
98 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
100 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
101 preprocessor macro arguments in traced name.
102 * doc/autoconf.texi (Defining symbols): Document longstanding
103 support for AC_DEFINE-ing macros with arguments, and document
104 behavior when the same variable has multiple AC_DEFINEs.
105 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
106 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
107 macros directly, giving much shorter and simpler code.
109 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
111 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
112 space before "$ac_configure_args" to prevent a 'config.status
113 --recheck' failure if ac_configure_args doesn't contain a leading
114 space. This works around a problem with the XEmacs configure.ac,
115 which uses the (undocumented) ac_configure_args variable
116 inconsistently with Autoconf.
118 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
120 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
121 Include <limits.h>, and use its INT_MAX to rewrite the
122 j loop so that it does not overflow 'int'. Problem reported by
123 Ralf Wildenhues in
124 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
125 Play it safe by shifting left by 1 rather than multiplying by 2,
126 as GCC is less likely to optimize this away when the value
127 is signed (when it assumes overflow leads to undefined behavior).
128 Also, don't assume time_t uses two's complement.
130 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
132 * tests/torture.at (Substitute a 2000-byte string): Avoid using
133 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
134 dumps core on it. Report by Tim Rice.
136 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
138 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
139 --disable-option-checking to --help output even when
140 AC_PRESERVE_HELP_ORDER is not used.
141 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
142 --with argument, rather than argument with [-.] replaced by
143 underscores.
144 * NEWS: Fix typo in previous change; the news was in the
145 wrong section.
147 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
149 * NEWS: Warnings are now generated by default for unknown
150 --enable-* and --with-* options.
151 * doc/autoconf.texi (Option Checking): Renamed from
152 (Configure Option Checking). Tighten up the wording a bit.
153 (External Software, Package Options): Cross-reference to Option
154 Checking, and use this to shorten our section.
155 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
156 "$x" to test "x$foo" != x.
157 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
158 Don't warn if $enable_option_checking is "no".
159 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
160 ac_unrecognized_opts to the empty string.
161 Don't echo the unrecognized opts, as this might mishandle
162 backslashes or leading -.
163 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
164 usage next to the other --disable-FEATURE options in the
165 help string.
167 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
169 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
170 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
171 Print warning for unrecognized --with and --enable options
172 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
173 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
174 Disable option checking when subdirs are configured.
175 (AC_OUTPUT): If warnings are enabled, print warning about
176 unrecognized --with and --enable options at the end of
177 the configure output (as well as at the beginning).
178 * doc/autoconf.texi (Option Checking): New node.
179 Document new option warning functionality.
181 2006-12-16 Eric Blake <ebb9@byu.net>
183 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
184 * NEWS: Start news for current version.
186 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
188 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
189 Define HAVE_GETMNTENT to 1, not to the empty string.
190 Problem originally reported by Jochen Friedrich in
191 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
193 This change prompted by a problem report by Andrey Simonenko in
194 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
195 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
196 object-like macros only, in the traditional portable character
197 set.
198 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
199 Warn about attempts to define things that are not identifiers.
200 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
201 awful hack that AC_DEFINEd macro names containing parentheses.
203 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
205 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
206 too drastic, even if Texinfo in theory requires it for info mode.
208 (config.status Invocation): Renamed back from Recreating a
209 Configuration).
210 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
211 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
213 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
215 * NEWS: Version 2.61a.
217 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
218 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
220 * NEWS: Document changes with echo and printf, and the lack
221 of limits on the total size of multi-line values of substituted
222 variables, and the AC_FUNC_FSEEKO fix.
224 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
226 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
227 Writing configure.ac.
228 (Autoconf Input Layout): Renamed from configure.ac Layout.
229 (Recreating a Configuration): Renamed from config.status Invocation.
230 (Obsolete Recreation): Renamed from Obsolete config.status Use.
231 (acconfig Header): Renamed from acconfig.h.
232 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
233 (Writing Testsuites): Renamed from Writing testsuite.at.
234 (Autom4te Cache): Renamed from autom4te.cache.
236 * BUGS: Remove mention of VPATH problem, since it's now documented
237 not to be a bug in the Autoconf build procedure itself, but rather
238 a problem with the proprietary `make' programs.
240 * doc/autoconf.texi (Build Directories): Add a cross reference
241 to VPATH and Make.
243 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
244 * doc/standards.texi: Sync from gnulib.
246 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
247 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
248 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
249 generated automatically.
251 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
253 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
254 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
255 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
257 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
259 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
260 `CEOF$ac_eof' special marker, the awk script cannot contain a
261 line matching `^CEOF', so this is not needed any more.
262 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
263 special marker in the test.
265 2006-12-06 Stepan Kasal <kasal@ucw.cz>
267 * tests/tools.at (autom4te preselections): Use `find -newer';
268 remove one of the sleeps.
270 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
271 more readable, using ...
272 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
274 * doc/autoconf.texi (autoheader Invocation): Do not double-
275 quote the parameter of `AH_BOTTOM' in the example.
277 2006-12-05 Stepan Kasal <kasal@ucw.cz>
279 * doc/autoconf.texi (Configuration Headers): Remove the
280 example with multiple input files.
281 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
282 multiple input files.
284 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
286 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
287 creating the awk substitution script, handle one input line at a
288 time, so that the maximum length of a substituted (multi-line)
289 value is not limited by the size of the sed pattern space.
290 The trade-off is a slightly repetitive sed script.
291 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
292 can only have up to 7 characters, due to Solaris 10 /bin/sed.
293 * tests/torture.at (Substitute a 2000-byte string): Increase the
294 test with several long lines, they should not be caught by sed
295 limits any more.
297 * tests/tools.at (autom4te preselections): New test, to flag
298 entries missing from autom4te.cfg.
299 Report by David Byron <dbyron@hheld.com>.
301 * tests/torture.at (Substitute a 2000-byte string): Actually use
302 AC_PROG_AWK, so the last change works as intended.
303 (Substitute and define special characters): Likewise.
304 (Substitute a newline): Likewise.
306 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
307 instead of `awk' consistently.
308 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
309 * tests/torture.at (Torturing config.status): Test both the
310 result of AC_PROG_AWK and plain awk.
311 (Substitute a 2000-byte string): Likewise.
312 (Substitute and define special characters): Likewise.
313 (Substitute a newline): Likewise.
315 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
317 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
318 can be assigned to a function pointer. Problem reported by
319 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
320 part of a patch by Ralf Wildenhues in that same bug report.
322 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
324 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
325 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
327 2006-12-01 Eric Blake <ebb9@byu.net>
329 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
330 cross-compiling from cygwin to mingw.
331 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
332 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
333 to lib/autoconf/c.m4.
335 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
337 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
338 string for more reliable failure. Wrap the entire test that
339 causes the broken Solaris printf to dump core, in a subshell,
340 so the segmentation fault message is reliably suppressed.
341 Fix shell expansion errors by using /usr/ucb/echo always;
342 avoid an error on systems without it by another subshell.
343 Avoid m4 expansion of `$1'. Set the zeroth argument of the
344 subshell-$as_echo to `as_echo', for better error message.
346 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
348 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
349 `BASH_SOURCE' contain a newline, set them to empty, as they may
350 not be unset.
352 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
354 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
355 years and is too hard to maintain now. The last straw was
356 reported by Jerker Baeck in
357 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
358 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
359 * doc/autoconf.texi (Particular Functions): Move
360 AC_FUNC_SETVBUF_REVERSED from here...
361 (Obsolete Macros): ... to here. Say that it does nothing now.
362 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
363 Turn into (almost) a no-op.
365 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
366 (AC_C_VOLATILE):
367 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
368 These macros are obsolescent and new applications shouldn't need them.
369 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
370 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
371 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):
372 (AC_FUNC_STRFTIME, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
373 (AC_FUNC_VPRINTF): Likewise.
374 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT, AC_HEADER_STAT):
375 (AC_HEADER_STDC, AC_HEADER_SYS_WAIT, AC_HEADER_TIME): Likewise.
376 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
378 * doc/autoconf.texi (Setting Output Variables): Mention that
379 @VAR1@VAR2 has unspecified behavior. Problem reported by
380 Ralf Wildenhues.
381 * NEWS: Mention this.
383 * Makefile.am: Put only a single '#' into the copyright notice,
384 so that it's also present in the output file. Standardize wording
385 in makefile copyright notices to match GNU coding standards.
386 * bin/Makefile.am: Likewise.
387 * doc/Makefile.am: Likewise.
388 * lib/Makefile.am: Likewise.
389 * lib/freeze.mk: Likewise.
390 * lib/autoconf/Makefile.am: Likewise.
391 * lib/autoscan/Makefile.am: Likewise.
392 * lib/autotest/Makefile.am: Likewise.
393 * lib/m4sugar/Makefile.am: Likewise.
394 * man/Makefile.am: Likewise.
395 * tests/Makefile.am: Likewise.
396 * lib/emacs/Makefile.am: Remove copyright notice; it's just a
397 one-line file.
399 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
401 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
402 in the sed script that mangles the awk script: delete up to the
403 first exclamation mark only.
404 * tests/torture.at (Substitute and define special characters):
405 Test '!' too.
407 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
409 Rewrite config files generation: avoid quadratic growth in
410 the number of substituted variables by using awk instead of sed
411 for the bulk of the substitutions.
412 * NEWS: Mention this.
413 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
414 forbidden in the output (and thus input) file.
415 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
416 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
417 generate just one large awk script for substitutions,
418 eliminating much of the earlier complexity, while adding some
419 new complexity. Only expand the substitution templates at
420 configure time, for smaller configure script size. If
421 _AC_SUBST_FILES are used, test 'awk' for working getline support
422 at config.status time. If absent, interpolate through the
423 shell. The awk script was written with much help
424 from Paolo Bonzini and Paul Eggert.
425 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
426 (_AC_SED_FRAG_NUM): Likewise.
427 (_AC_SUBST_CMDS): Renamed from...
428 (_AC_SED_CMDS): ...this.
429 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
430 * tests/torture.at (Substitute a 2000-byte string): Also
431 substitute a line with 1000 words, and a variable with several
432 long lines.
433 (Substitute and define special characters): Test awk special
434 characters, and put substitution input strings `@foo@' in the
435 output, to test that no recursion happens; test several other
436 combinations from Paolo Bonzini.
438 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
440 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
441 that replaced echo with AS_ECHO where this wasn't necessary.
442 Problem reportd by Ralf Wildenhues.
443 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
444 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
445 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.
447 2006-11-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
449 * lib/freeze.mk (GREP): Removed, no need to initialize this.
451 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
453 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
454 that traditional Awk lacks 3-arg "split". It has it.
455 Mention that FS must be a single character, and a few other
456 99-byte limits of traditional Awk.
457 Mention that if (i in a) doesn't work with traditional Awk.
459 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
461 * tests/autotest.at (BSx641-newline in command):
462 (BS-BS-newline in command, BSx640-newline in command):
463 (Newline-CODE-BS-newline in command):
464 (Single-quote-BS-newline in command):
465 (Single-quote-newline-BS-newline in command):
466 Use printf '%s\n' instead of echo, for portability to hosts
467 where echo interprets backslashes. This will break on hosts

469 are dead (if not, we should get reports of test failures).

473 'echo' has some portability problems, when given a first argument
474 with a leading '-', or when given any argument containing '\'.
475 Avoid using 'echo' in these cases.

479 * lib/autotest/general.m4 (AT_INIT): Likewise.
480 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
481 argument might be unportable.

500 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.

503 * lib/autotest/general.m4 (AT_INIT): Likewise.
504 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):

507 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
508 rather than using a here-document to put the script into a file.

510 use AS_ECHO.

512 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
513 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any

520 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
521 Don't set as_nl, since _AS_ECHO_PREPARE does that now.

528 * configure.ac (AC_INIT): Bump to 2.61a.
529 * NEWS: Likewise.

536 * NEWS: Likewise.

623 and Joel E. Denny <jdenny@ces.clemson.edu>
624 and Paul Eggert <eggert@cs.ucla.edu>
626 * tests/autotest.at (AT_CHECK_AT_TITLE): Fix shell quoting bugs
627 and non-portable sed scripts, and use $CONFIG_SHELL when invoking
628 ./micro-suite.
630 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>
632 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
633 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
634 Imported from a similar patch to gnulib by Bruno Haible.
636 2006-11-08 Paul Eggert <eggert@cs.ucla.edu>

654 2006-10-26 Joel E. Denny <jdenny@ces.clemson.edu>
655 and Stepan Kasal <kasal@ucw.cz>
657 Handle special characters in test case titles correctly.
658 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
659 properly.
660 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
661 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST
662 argument. Extend to check titles printed by ./micro-suite and
663 ./micro-suite -l and the title in micro-suite.log.

665 Single-quote in a test title,
666 Double-quote in a test title): Don't expect failure anymore.
667 (Backslash in a test title): Put a non-whitespace character after the
668 backslash so that Bourne shells might actually see it as an escape
669 sequence.
670 (Brackets in a test title,
671 Pound in a test title,
672 Comma in a test title,
673 Quoted Macro in a test title,
674 Macro in a test title,
675 Macro with single-quote in a test title): New tests.
676 (Macro with backquote in a test title,
677 Macro with double-quote in a test title,
678 Macro with backslash in a test title): New tests expected to fail.
679 * tests/torture.at (#define header templates): M4-quote this title in
680 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
681 The visible effect was a stray [] in the testsuite output.
683 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
685 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
686 `trap ... 0' inside a function, for AIX sh.
688 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
690 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
691 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
692 5363) simply issues a warning when dividing by zero at compile
693 time. Problem reported by Elias Pipping.
695 2006-10-26 Eric Blake <ebb9@byu.net>
697 * THANKS: Update.
698 * doc/autoconf.texi (Evaluation Macros): Improve the example to
699 show effect on macros that expand with commas.
700 Reported by Joel E. Denny.

724 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
726 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
727 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
728 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
729 reported by Nelson H. F. Beebe for Coreutils 6.4.
731 * tests/tools.at (autoconf --trace: user macros): Remove test
732 for tracing multiline macros, since m4 1.4.7a uses a different
733 way to number lines. Problem reported by Ralf Wildenhues.
735 2006-10-24 Stepan Kasal <kasal@ucw.cz>
737 * bin/autom4te.in (handle_m4): Do not redirect stdin to
738 /dev/null since the heuristics for interactive behaviour was
739 fixed in CVS m4.
741 * bin/autom4te.in: With --force, always refresh the output
742 file. Problem reported by Greg Schafer <gschafer@zip.com.au>.
744 * bin/autoconf.as: Fix the verbose message at the end.
746 2006-10-23 Paul Eggert <eggert@cs.ucla.edu>

757 * build-aux/texinfo.tex: automake 1.10
759 * NEWS: Remove AC_CACHE_CHECK_INT.
760 * doc/autoconf.texi (Caching Results): Likewise.
761 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
762 AC_CACHE_CHECK_INT, since it's no longer public.
763 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
764 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.
766 2006-10-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

775 m4_mkstemp.
776 * doc/autoconf.texi (Redefined M4 Macros): Document m4_mkstemp.
777 * NEWS: Likewise.
779 2006-10-16 Eric Blake <ebb9@byu.net>
781 * doc/autoconf.texi (Setting Output Variables): Fix typo.
783 * bin/autoconf.as (version): Reword to match GNU Coding
784 Standards.

792 2006-10-14 Stepan Kasal <kasal@ucw.cz>
794 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
795 looking for special shell characters.
796 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
797 macro defined by AS_VAR_PUSHDEF before passing it as a
798 parameter.
799 * lib/autoconf/general.m4 (AC_CHECK_FILE, AC_CHECK_DECL):
800 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS, AC_CHECK_LIB):

809 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
811 (Imported from Automake.)
812 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
813 which incorrectly sets the mode of an existing destination
814 directory. In some cases the unpatched install-sh could do the
815 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
816 system. We hope this is rare in practice, but it's clearly worth
817 fixing. Problem reported by Alex Unleashed in
818 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
819 Also, don't bother to check for -m bugs unless we're using -m;
820 suggested by Stepan Kasal.
822 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>

829 Report from Bruno Haible.
831 2006-03-10 Alexandre Duret-Lutz <adl@gnu.org>

840 Import this change from Gnulib:
842 2006-09-16 Karl Berry <karl@gnu.org>
843 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
844 to avoid sectioning errors.
846 Import these changes from Texinfo:

852 (\lquoteexpand, \quoteexpand): new defs.
853 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
854 (\code): must use new \...Char values, since now ` is active.
856 2006-08-26 Karl Berry <karl@gnu.org>
857 * build-aux/texinfo.tex (\textdegree): New command.
859 2006-08-12 Karl Berry <karl@gnu.org>

866 2006-10-13 Stepan Kasal <kasal@ucw.cz>
868 * doc/autoconf.texi (Autoheader Macros): Warn that the text
869 added to the template can get mangled.
871 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
873 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
874 include the default headers, and redefine obstack_chunk_alloc
875 and obstack_chunk_free. Fixes false failure with glibc.
877 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
879 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

881 by Ralf Wildenhues.
883 2006-10-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
885 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL): Require
886 AC_PROG_CC.

889 2006-10-11 Paul Eggert <eggert@cs.ucla.edu>
891 * NEWS: AC_USE_SYSTEM_EXTENSIONS now defines _TANDEM_SOURCE for
892 the NonStop platform.
893 * doc/autoconf.texi (Posix Variants): Likewise.
894 * lib/autoconf/specific.m4 (AC_USE_SYSTEM_EXTENSIONS): Likewise.
896 * lib/m4sugar/m4sh.m4 (AS_TEST_X): New macro.
897 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
898 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
899 Use a better substitute, by inspecting the output of "ls"
900 rather than just using ":".
901 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
902 rather than AS_EXECUTABLE_P, since we needn't worry about
903 non-regular files here.
905 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
906 due to configuration hassles with this. See Tonya Underwood's report
907 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

916 2006-10-11 Stepan Kasal <kasal@ucw.cz>
918 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Move the

930 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
931 comment about ac_cpp_err; it was incorrect, and anyway
932 ac_cpp_err is being removed below.
933 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
934 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
935 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
936 nobody uses it.
937 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
938 with werror_flag and conftest.err and so forth. This is more
939 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
940 and anyway the user shouldn't normally want to see this gorp logged.
941 Problem reported by Ralf Wildenhues.
942 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
943 empty, not 'no', since the rest of the code uses 'test -z'.
945 2006-10-04 Paul Eggert <eggert@cs.ucla.edu>
947 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

951 Problem reported by mwoehlke in
952 <http://lists.gnu.org/archive/html/bug-coreutils/2006-10/msg00048.html>.
954 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
955 than creating a file to use with test -x; this is much faster.
957 2006-10-02 Bruno Haible <bruno@clisp.org>
959 * lib/autom4te.in (Automake-preselections): Add
960 AM_GNU_GETTEXT_INTL_SUBDIR, for automake 1.10.
962 2006-09-27 Stepan Kasal <kasal@ucw.cz>
964 * doc/autoconf.texi (Writing testsuite.at): Fix a typo: for
965 standard error, `experr' should be used, not `expout'.
967 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
969 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Don't compile the
970 fseeko testing program twice; just use the earlier result.
971 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):

975 failed.
977 * lib/autoconf/functions.m4: Fix problems reported by Ralf Wildenhues.
978 (AC_FUNC_ERROR_AT_LINE): Don't bother to check for error.h. Just
979 include it, without including anything else.

990 for a declaration of wait3.
992 2006-09-26 Paul Eggert <eggert@cs.ucla.edu>
994 * NEWS: AC_CHECK_DECL now also works with aggregate objects.
995 * doc/autoconf.texi (Generic Declarations): Clarify that AC_CHECK_DECL
996 can apply to constants too, and that it checks for macro defns.
997 * lib/autoconf/general.m4 (AC_CHECK_DECL): Assume C89 or better,

999 values. Problem reported by Ralf Wildenhues.

1088 * doc/autoconf.texi (Input): Clarify role of AC_CONFIG_MACRO_DIR.
1089 * lib/autoconf/general.m4 (AC_CONFIG_MACRO_DIR): Do not check

1091 too late, anyway. Problem reported by Stefan Seefeld.
1093 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Avoid bug in UnixWare
1094 7.1.4 /usr/bin/posix/sh described by Tim Rice in
1095 <http://lists.gnu.org/archive/html/bug-autoconf/2006-09/msg00017.html>.
1097 2006-09-11 Stepan Kasal <kasal@ucw.cz>
1099 * tests/local.at (AT_CHECK_M4): Fix this so that the testsuite
1100 works with GNU M4 1.4.3 again; make the normalized form
1101 match the current m4 message; fix the description.

1107 to catch glibc bug 2821
1108 <http://sourceware.org/bugzilla/show_bug.cgi?id=2821>.
1110 Merge from gnulib as follows: Use AC_CHECK_HEADERS_ONCE instead of
1111 AC_CHECK_HEADERS, and likewise for AC_CHECK_FUNCS_ONCE and
1112 AC_CHECK_FUNCS. Don't check for stdlib.h, since we now
1113 assume C89.

1135 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Prefer xlf90/xlf95 over
1136 f90/f95 because the latter drivers of AIX Fortran 9.1 do not
1137 accept files with extension `.f'. For consistency, also prefer
1138 xlf over f77.
1139 * doc/autoconf.texi (Fortran Compiler): Remove mention of bug

1161 except the first two arguments are reversed.
1162 * doc/autoconf.texi (Caching Results): New macro AC_CACHE_CHECK_INT.
1163 (Generic Compiler Characteristics): AC_COMPUTE_INT no longer
1164 caches nor outputs a diagnostic. Suggested by Bruno Haible.

1211 deal with LEXLIB.
1212 (_AC_PROG_LEX_YYTEXT_DECL): Handle caching correctly; the old code
1213 didn't work if some values were cached but not others. Test for
1214 broken lex libraries like native ia64-hp-hpux11.22; see
1215 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and
1216 work around the problem by preferring an empty LEXLIB to -lfl or
1217 -ll. Let the user set LEXLIB='' to indicate no library needed.
1219 * NEWS: Recommend M4 1.4.6 instead of 1.4.5.
1220 * README: Likewise.
1221 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.

1374 * lib/autoconf/libs.m4 (AC_PATH_X_DIRECT): Replace another
1375 check for libXt by a check for libX11.
1377 2006-08-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1379 * doc/autoconf.texi (config.status Invocation): Adjust according
1380 to last change.
1382 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1384 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1385 --help' should mention that `--version' outputs configuration
1386 settings. Report by Bruno Haible.
1388 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1390 Fix test suite failures reported by Pierre in
1391 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1392 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1393 the compiler created a file "b.out" when it didn't create anything
1394 at all.
1395 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1396 Discard stderr too, when invoking the test script.
1398 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
1400 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
1401 in the restoring of the werror flag.
1403 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1405 * doc/autoconf.texi (Volatile Objects): Be even a little
1406 less skeptical about "volatile", after discussion with
1407 Bruno Haible on bug-gnulib.
1408 (Limitations of Usual Tools): Warn about sed stripping
1409 leading white space from text. From Bruno Haible.
1411 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1413 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1414 compiler complains about it, even if things works after the
1415 complaint. Problem reported by Peter O'Gorman.
1417 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1418 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1419 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1421 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1423 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1424 after -R regardless of host. Patrick Welche reports that this
1425 fixes things on NetBSD 3.99.
1427 * NEWS: Recommend M4 1.4.5.
1428 * README: Likewise.
1429 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1430 * tests/tools.at (autom4te cache): Update wording of diagnostic
1431 to match M4 1.4.5.
1433 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1435 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1436 under AC_C_VOLATILE.
1437 (Volatile Objects): Be a little less skeptical about what
1438 "volatile" means. Derived from thoughts by Ben Pfaff in
1439 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1441 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1443 * doc/autoconf.texi: Fix some typos.
1445 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1447 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1448 more globally, since the 2006-06-30 patch didn't suffice. Problem
1449 reported by Keith Marshall. Also, don't bother with builddir2,
1450 since it shouldn't be needed any more.
1452 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1454 * doc/autoconf.texi (Generic compiler characteristics):
1455 Document AC_COMPUTE_INT. Fix wrong statements on Default
1456 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1458 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1459 (_AC_COMPUTE_INT): Add obsoletion warnings.
1460 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
1461 AC_COMPUTE_INT.
1463 * NEWS: Document change.
1465 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1467 * doc/autoconf.texi (Volatile Objects): New section.
1469 * NEWS: Document previous change.
1471 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1473 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1474 Require that long long int be at least 64 bits wide. C99 requires
1475 this and enough programs depend on it so we should check for it.
1476 Bruno Haible reports in
1477 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1478 that long long int is 32 bits wide with some nonstandard compilers.
1479 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1481 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1483 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1484 to a nonexistent file, so that we don't have to worry about
1485 a local site configuration that doesn't use /usr/local.
1486 Problem reported by Keith Marshall in
1487 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1489 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1491 * doc/autoconf.texi: Be more consistent about using @acronym with
1492 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1493 quite right (it talked about "OSF/Tru64", even though the
1494 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1495 and it even mentioned "OSF 4"!) and at this point there's little
1496 reason to talk about OSF any more, since it died in 1994.
1497 (Specific Compiler Characteristics): Simplify example of
1498 negative-size array.
1499 (File Descriptors): Reorder to make the text flow better.
1500 Remove joke about "appreciate the various levels"; I didn't get it.
1501 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1502 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1503 (File Descriptors, Limitations of Usual Tools):
1504 Tone down the advice against renaming or removing open files.
1505 (Limitations of Usual Tools): Add a new section, on 'rm'.
1507 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1509 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1510 -lXt in LIBS, idea from Karsten Hopp; this was due since
1511 this change:
1513 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1514 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1515 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1516 (which belong to Xt, not X itself). See Debian bug 327655.
1518 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1520 * configure.ac (AC_INIT): Bump to 2.60a.
1521 * NEWS: Update.
1523 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1525 Version 2.60.
1527 * configure.ac, NEWS: Update.
1529 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1531 * config/texinfo.tex: Sync from upstream.
1533 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1534 quadrigraph correctly in traces.
1536 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1537 Fix typos.
1539 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1540 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1541 not defined.
1542 * doc/autoconf.texi (Changed Directory Variables): New node,
1543 to document the whole `datarootdir' business a bit better.
1544 * NEWS: Update.
1545 * tests/torture.at (datarootdir workaround): Extend test.
1546 Prompted by report by Alexandre Julliard.
1548 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1550 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1551 when using default mode of IBM C 6 for AIX. Problem and two-line
1552 fix reported by Larry Jones.
1554 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1556 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1557 about literal '${datarootdir}' if a definition is found in the
1558 output file.
1560 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1562 * NEWS: Use "M4" rather than "m4" when appropriate.
1563 Problem reported by Eric Blake.
1564 * doc/autoconf.texi: Likewise.
1565 Use @acronym around BSD, GCC, and GNU when appropriate.
1566 (Why GNU M4): Renamed from "Why GNU m4".
1567 (Redefined M4 Macros): Mention that Posix
1568 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1569 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1570 to int.
1572 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1574 * bin/autom4te.in (handle_output): Do not forbid the empty
1575 pattern.
1576 * tests/tools.at (autoconf: the empty token): New test.
1578 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1580 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1581 calls, so that we do not care whether they are LIFO or FIFO;
1582 in the m4_wrap, do not check which diversion is the topmost
1583 one, just check that the stack is balanced at the end.
1584 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1585 base diversion forever--pop the previous diversion before
1586 opening the new one; consequently, remove the m4_wrap call.
1587 * lib/autotest/general.m4 (AT_INIT): Likewise.
1588 * tests/m4sugar.at: Do not use
1589 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1591 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1592 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1594 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1595 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1596 Rework example of m4wrap token-pasting trouble so that it doesn't
1597 care whether it's LIFO or FIFO.
1598 Fix some "contrary to"s that are awkward in English.
1600 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1602 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1603 to `yes' instead of `int$1_t' if the type is found, for more
1604 consistent configure output (where $1 is the number of bits).
1605 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1606 Suggested by Bruno Haible.
1608 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1609 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1610 with system headers. Report by Bruno Haible.
1612 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1614 * config/config.guess, config/config.sub: Sync from upstream.
1616 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1617 in order to avoid picking up an older installed frozen m4sh.m4f.
1618 Besides an outdated shell startup, this could have been created
1619 by an earlier M4 version with incompatible frozen file format.
1621 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1623 * README: Recommend m4 1.4.4 instead of 1.4.3..
1624 * doc/autoconf.texi: Likewise.
1625 (Special Chars in Names): Say that $(.FOO) is portable, as
1626 suggested by Stepan Kasal.
1627 (Installation Directory Variables, Build Directories):
1628 (Automatic Remaking, Subdirectories, Fortran Compiler):
1629 (Making testsuite Scripts, Defining Directories):
1630 Quote variable usages better.
1631 (Making testsuite Scripts): Add clean-local rule to makefile
1632 snippet, by Eric Blake.
1633 (Installation Directory Variables): Fix table item font.
1634 Reword slightly to clarify. Generalize advice about
1635 not using special characters to include all file-related
1636 vars, not just VPATH.
1637 (Special Chars in Variables): Warn about special characters in
1638 $(srcdir) too.
1639 (Assignments): Clarify default-value example as suggested by
1640 Ralf Wildenhues in
1641 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1642 (Special Shell Variables): Note leading ./ or ../, as suggested
1643 by Eric Blake.
1644 (Limitations of Builtins): Under cd, warn about CDPATH.
1645 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1646 Ralf Wildenhues.
1648 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1650 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1651 `@var', for texi2html.
1652 (Systemology): Some more word wrapping, for DVI output.
1653 (autom4te Invocation): The short option for `--melt' is `-M',
1654 not `-m'.
1656 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1658 * doc/autoconf.texi: More formatting and English tweaks,
1659 many suggested by Ralf Wildenhues.
1660 Reword to avoid "@code{...}'s" and the like, since it's ugly
1661 with Emacs info mode. discontents -> woes.
1662 Put a few "will"s back. time stamp -> timestamp.
1663 side-effect -> side effect.
1665 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1667 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1668 Warn about $@ not persisting. Problem reported by Julien Danjou in
1669 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1670 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1671 Mention other special chars, too.
1673 2006-06-14 Eric Blake <ebb9@byu.net>
1675 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1677 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1679 * doc/autoconf.texi: Some systematic minor improvements, as
1680 follows. Use "makefile" when talking about makefiles
1681 generally (which might be named "makefile" or "Makefile" or even
1682 "foo.mk"), "Makefile" when talking about a specific makefile
1683 called "Makefile". This unclutters the text from weird quotes
1684 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1685 values" rather than "@var{foo}s" and similar constructs containing
1686 "}s". Use "Make rules" rather than "Makefile rules". Minor
1687 English-language improvements. Change the prefix "sub-" to "sub"
1688 and "re-" to "re".
1689 Put blank lines around examples more consistently.
1690 Avoid "rather" and "very" as intensifiers.
1691 Avoid "will" as an auxiliary.
1692 (Limitations of Make): Split this node into....
1693 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1694 (Leading _ in Macro Names, Backslash-Newline-Newline):
1695 (Backslash-Newline Comments, Long Lines in Makefiles):
1696 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1697 (obj/ and Make, make -k Status, VPATH and Make):
1698 (VPATH and Double-colon, $< in Explicit Rules):
1699 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1700 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1701 New nodes, resulting from splitup of Limitations of Make.
1702 All cross-references changed. Raise the top node from
1703 a section to a chapter, and all subnodes accordingly.
1704 Redo the introductory wording to match the new organization.
1705 (Installation Directory Variables): Use an example that is
1706 closer to what Autoconf actually does. Mention that VPATH's
1707 value should not contain metacharacters or white space.
1708 (Fortran Compiler): Fix a VPATH bug in an example.
1709 (Leading _ in Macro Names): Mention that this problem is no longer
1710 of practical concern.
1711 (VPATH and Make): Reword the advice to make it clearer
1712 that Autoconf and Automake support VPATH in non-GNU make, but
1713 many packages have bugs in this area.
1714 ($< in Explicit Rules): Refer to Build Directories rather
1715 than using a (non-VPATH-safe) example.
1716 (Automatic Rule Rewriting): Mention the sort of disaster that
1717 can ensue with Solaris-style rule rewriting with VPATH.
1719 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1721 * doc/install.texi (Compilers and Options): Weaken the
1722 suggestion to use GNU make for VPATH builds.
1724 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1725 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1727 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1728 in regular expression.
1730 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1732 * doc/autoconf.texi (Installation Directory Variables):
1733 Drop extra @samp from `@table @samp' item.
1734 (Limitations of Usual Tools): Comment fix.
1735 Do not nest @samp just to point to other table items.
1736 (Writing testsuite.at) <AT_CHECK>: The second argument to
1737 `@dvar' is already @samp'ed.
1738 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1739 do not use @var in the second argument.
1741 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1743 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1744 $as_shell.exe too. Problem reported by Andreas Buening in
1745 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1747 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1749 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1750 `unused variable' compiler warning, for `-Wall -Werror'.
1751 Reported by Jaap Haitsma in
1752 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1754 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1756 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1757 case the compiler dumps core. Problem reported for
1758 OpenServer 5.0.7 by Tim Rice in
1759 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1760 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1761 Likewise.
1763 2006-06-06 Tim Rice <tim@multitalents.net>.
1765 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1766 "ERROR" only shows up in "make check" output if there is an
1767 error.
1769 2006-06-06 Eric Blake <ebb9@byu.net>
1771 * tests/tools.at (automatically allowed tokens): Fix typo.
1773 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1775 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1777 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1
1778 typically overflows on x86 CPUs, even though the C standard
1779 requires otherwise.
1781 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1783 * configure.ac (AC_INIT): Bump to 2.59e.
1784 * NEWS: Update.
1786 2006-06-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1788 Version 2.59d.
1790 * config/texinfo.tex: Sync from upstream.
1792 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1793 seen, invoke libtoolize with `--ltdl' argument.
1794 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1795 * NEWS: Update.
1796 Suggested by Eric Blake.
1798 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1800 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem
1801 reported by Ralf Wildenhues.

1818 * tests/local.at (AT_CHECK_M4): New macro, almost identical
1819 to...
1820 (AT_CHECK_AUTOM4TE): ... which is now a thin wrapper around
1821 AT_CHECK_M4.
1822 (AT_CHECK_AUTOCONF): Use AT_CHECK_M4; no longer support
1823 `expout' as the last parameter.
1824 * tests/tools.at: Adapt to the above change.
1826 2006-06-04 Stepan Kasal <kasal@ucw.cz>
1828 * doc/autoconf.texi (Limitations of Usual Tools): Correct
1829 information about race-free implementations of mkdir.
1831 2006-06-04 Eric Blake <ebb9@byu.net>
1833 * bin/autoreconf.in (help): Document M4 environment variable.
1834 * bin/autoconf.as (Usage): Likewise.

1840 * NEWS: GNU make now recommended for VPATH builds.
1841 Mention that some macros are now documented to be obsolescent.
1842 * doc/autoconf.texi:
1843 Prefer "current" to "modern" to describe
1844 currently-used (albeit perhaps old-fashioned) hosts.
1845 Mention which ancient features no longer need to be worried about.
1846 setgid -> set-group-ID
1847 setuid -> set-user-ID (these are the Posix terms)
1848 Fix some misuses of "only".
1849 (AC_C_BACKSLASH_A, AC_C_CONST, AC_C_PROTOTYPES):
1850 (AC_C_STRINGIZE, AC_C_VOLATILE, AC_FUNC_CLOSEDIR_VOID):
1851 (AC_FUNC_GETPGRP, AC_FUNC_LSTAT, AC_FUNC_MEMCMP):
1852 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP):
1853 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_STAT, AC_FUNC_STRFTIME):
1854 (AC_FUNC_STRNLEN, AC_FUNC_UTIME_NULL, AC_FUNC_VPRINTF):
1855 (AC_HEADER_DIRENT, AC_HEADER_STAT, AC_HEADER_STDC):
1856 (AC_HEADER_SYS_WAIT, AC_HEADER_TIME, AC_ISC_POSIX):
1857 (AC_PROG_GCC_TRADITIONAL, AC_STRUCT_TM):
1858 Mention that these macros are obsolescent.
1859 (Installation Directory Variables): shall -> should
1860 (File Descriptors): Mention that 0, 1, 2 might get reopened.
1861 Mention that it's now safe to use 3 and 4.
1862 (Limitations of Usual Tools): cp -r is now specified by Posix.
1863 Omit longwinded and obsolescent discussion of cp -f.
1864 Modernize discussion of expr, ls.
1865 (Limitations of Make): Modernize discussion of VPATH builds.
1866 Mention $? as a workaround in some cases.
1867 * doc/install.texi (Basic Installation):
1868 Mention "./configure; make; make install" first. Be more
1869 specific about why this file is generic. Remove unnecessary
1870 parens. Remove misleading "only". Remove obsolete advice
1871 about csh. Don't say "configure" takes awhile; say it
1872 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1873 and CC=c99 rather than CC=c89, as these are blessed by current
1874 Posix. Recommend GNU make if doing a VPATH build.
1876 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1878 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1879 examples involving shell prompts.
1881 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1882 and Paul Eggert <eggert@cs.ucla.edu>
1884 * doc/autoconf.texi (Here-Documents): Add details about the
1885 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1886 use "here-documents" instead of "here documents".
1888 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1890 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1892 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1894 * doc/autoconf.texi (File System Conventions): Warn about ":"
1895 anywhere in directory names.
1897 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1899 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1900 about quoting the case statement, just in case.
1901 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1902 was fixed in ksh93g; reported by Ralf Wildenhues.
1904 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1906 * doc/autoconf.texi (System Services): Do not document
1907 overriding EXEEXT via ac_cv_exeext=ext.
1908 (Particular Programs) <AC_PROG_MKDIR_P>:
1909 Document that ${MKDIR_P} understands --.
1910 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1911 comment.
1913 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1915 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1916 argument with leading hyphen. Problem reported by Paul Eggert.
1918 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1920 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1921 about quoting ac_try: quote all of it, if any of it seems suspicious.
1922 This means we don't have to worry about ${ or sed any more.
1923 Also, double-quote the case statement, to work around misuses via
1924 underquoting as reported by Ralf Wildenhues in
1925 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1926 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1927 undocumented and dangerous macro.
1928 Problem reported by Ralf Wildenhues in
1929 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1931 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1933 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1934 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1935 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1937 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1939 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1940 since evidently some packages rely on the old, broken behavior.
1941 Problem reported by Ralf Wildenhues in
1942 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1943 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1944 pre-2006-05-26 definitions, but leave in the comments that
1945 these macros are dangerous and should not be used.
1946 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1947 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1948 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1949 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1950 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1952 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1954 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1955 the use of 'tr', since this is our only use of 'tr'.
1957 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1958 and Paul Eggert <eggert@cs.ucla.edu>
1960 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
1961 Don't assume 'grep' works on long lines, since AIX grep doesn't.
1963 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1965 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
1966 the output file in the `${datarootdir}' test.
1968 2005-05-28 Stepan Kasal <kasal@ucw.cz>
1969 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1971 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
1972 mention of `datarootdir' in the input file(s), but literal
1973 `${datarootdir}' in the output file, and we haven't warned yet,
1974 then warn as well: the user may have (erroneously) used
1975 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
1976 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
1977 * tests/torture.at (datarootdir workaround): Extend this test.
1978 * NEWS: Update.
1980 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1981 and Paul Eggert <eggert@cs.ucla.edu>
1983 * doc/autoconf.texi (autoheader Invocation): The first argument to
1984 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
1985 alternatives and clear up the language a bit.
1987 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
1989 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
1990 ac_config_guess, ac_config_sub, ac_configure.
1991 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
1992 Fix typo that prevented an unnecessary space from being removed.
1993 Problems reported by Ralf Wildenhues in:
1994 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
1996 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
1998 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
1999 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2000 Don't use the term "thread-safe" to talk about mkdir race
2001 conditions, since the problem is more a process than a thread
2002 issue. Problem reported by Stepan Kasal in:
2003 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2004 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2005 the test for 'install' more closely. Look at MKDIR_P first.
2006 Look in the PATH, and at /opt/sfw/bin.
2007 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2008 Don't bother to try mkdir -p, since we already check mkdir --version;
2009 just look at the version number. (There's no easy way to check
2010 for race-free implementations.)
2011 * tests/tools.at (autoconf: subdirectories): Adjust to above
2012 changes, since MKDIR_P now might end in "/mkdir -p".
2014 * doc/autoconf.texi (autoheader Invocation): Mention that the
2015 first arg of AC_DEFINE_UNQUOTED must be a literal.
2016 Problem reported by Ben Pfaff in
2017 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2019 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2020 * doc/autoconf.texi (Special Chars in Variables): New section.
2021 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2022 (Installation Directory Variables): Quote $(datadir) better.
2023 (Limitations of Builtins): Describe some of eval's trickiness.
2025 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2026 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2027 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2028 in front of every arg, not just trailing args. Quote apostrophes.
2029 (_AC_EVAL_ECHO): New macro.
2030 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2031 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2032 removed.
2033 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2034 exposed by quoting of eval argument. Put the command on line line
2035 so it logs better.
2036 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2037 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2038 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2039 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2040 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2041 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2042 Use eval more safely.
2043 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2044 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2045 to be replaced.
2046 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2047 lines, exposed by quoting of eval argument.
2049 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2050 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2052 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2053 initialization of `ac_cv_exeext', do not override it if it was
2054 already set, unless it was set to `no', for compatibility with
2055 Autoconf-2.13, and comment this.
2056 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2057 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2058 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2059 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2060 Document that this test may be overridden by setting
2061 `ac_cv_exeext'.
2063 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2065 Revert these two patches:
2067 2006-04-06 Eric Blake <ebb9@byu.net>
2068 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2069 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2070 2006-04-01.
2072 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2073 Clean up _AC_COMPILER_EXEEXT* macros.
2074 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2075 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2076 ac_file to the name of the default output file and call
2077 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2078 initial `rm' of the candidate files...
2079 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2080 the same list in subsequent `rm' calls, and for the temporary
2081 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2082 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2083 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2084 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2085 no longer needed) by libtool. Make it a cache check.
2086 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2087 copied here by mistake.
2088 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2089 _AC_COMPILER_EXEEXT.
2090 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2091 _AC_COMPILER_OBJEXT directly.
2092 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2094 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2096 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2097 Fix description of how the buggy `sed' works.
2099 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2101 Sync from Automake:
2103 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2104 ENOLCK. Only mention `make -j' when applicable. Only raise
2105 fatal errors when `make -j' is involved. Improve error message.
2107 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2109 * doc/autoconf.texi (Here-Documents): We now know more about
2110 the variable expansion in here documents bug.
2111 Thanks to Tim Rice and Stepan Kasal.
2113 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2114 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2116 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2118 * tests/autotest.at (Multiline command from M4 expansion):
2119 No failure to be expected if the shell quotes newlines in
2120 commands in the `set -x' output. Report by Tim Rice.
2121 * THANKS: Update.
2123 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2125 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2126 expansion in the here-documents used by config.status, as that
2127 runs afoul of the Korn shell version M-12/28/93d bug described in
2128 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2129 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2130 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2132 2006-05-23 Jim Meyering <jim@meyering.net>
2134 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2135 Fix typo introduced with 2006-04-02 change. It reversed the sense
2136 of the test.
2138 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2140 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2141 ac_dB slightly, to save bytes in the script.
2142 Max out at 50 lines, rather than 96; this is more likely
2143 (though not guaranteed) to avoid obscure 'sed' failures.
2145 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2147 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2148 `tr -d -' as bad option argument. Work around this by deleting
2149 an unrelated character.
2150 Report by Tim Rice <tim@multitalents.net>.
2152 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2153 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2154 Stepan Kasal <kasal@ucw.cz>
2156 * doc/autoconf.texi (Particular Programs): Do not promise that
2157 we always prefer the GNU version of the program, and that we
2158 search according to PATH; both rules can have exceptions.
2159 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2160 AC_PROG_SED. Move descriptions of limitations
2161 to the Limitations of Usual Tools section.
2162 (Limitations of Usual Tools) <sed>: Mention script length
2163 limitations with Solaris /usr/ucb/sed.
2164 <grep>: Fix wording for empty alternative. Mention that -c and
2165 -l should not be combined, and that -E and -F should not be
2166 combined.
2168 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2169 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2171 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2172 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2174 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2176 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2177 AC_DEFINE is now passed to m4_pattern_allow.
2178 * NEWS: Mention that; likewise for AC_SUBST.
2179 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2180 the parameter to m4_pattern_allow.
2181 * tests/tools.at: Add a check for that.
2183 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2185 * lib/autoconf/status.m4: Fix typos.
2187 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2189 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2190 only the files that this macro generates.
2192 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2194 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2195 the HP-UX sed limitation of 99 commands, labels do not count.
2196 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2197 in the comment.
2198 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2200 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2202 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2203 Import the following fix from coreutils:
2205 2006-01-13 Jim Meyering <jim@meyering.net>
2207 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2208 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2209 not double-quote uses of that variable, to accommodate the rare
2210 case in which getmntent is available in none of the libraries
2211 checked. This happens at least on FreeBSD 5.0.
2213 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2215 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2216 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2217 some other programs unwisely rely on these undocumented vars.
2218 But put in warning comments about them.
2219 Problem reported by Ralf Wildenhues in
2220 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2221 * NEWS: Document that these variables are intended to go away.
2223 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2225 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2226 and set the language to C++ (analogous to the equivalent Fortran
2227 tests).
2229 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2230 * doc/autoconf.texi (C++ Compiler): Document it.
2231 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2232 * NEWS: Update.
2234 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2236 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2237 that caused config.status to generate 100-command sed scripts; the
2238 portable limit is 99.
2240 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2242 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2243 variable `ac_d' instead of `d' to avoid infringing namespace.
2244 Report by Ralf Menzel.
2246 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2248 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2249 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2250 * tests/tools.at (autoconf: subdirectories): New test, taken from
2251 the corresponding problem report by Ralf Wildenhues in:
2252 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2254 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2255 Quote some uses of shell variables if they might suffer unexpected
2256 globbing. This doesn't fix all instances of quoting problems that
2257 I found, just the easy ones that look safe.
2258 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2259 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2260 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2261 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2262 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2263 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2264 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2265 Likewise.

2267 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2269 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2271 * bin/autoreconf.in ($help): Reword according to the manual.
2272 Suggested by Olly Betts.
2274 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2275 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2277 * bin/autoreconf.in: Pass the directory argument to
2278 `require_configure_ac'. Fix comment.
2279 * tests/torture.at (Configuring subdirectories): Expose this.
2280 Reported by Olly Betts.
2282 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2284 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2285 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2286 Automake as follows:
2288 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2289 `$configure_in' instead of `configure.in', to preserve
2290 directory component.
2292 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2294 * config/config.guess, config/config.sub, config/texinfo.tex,
2295 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2297 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2299 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2300 test for C99 conformance; (bool) 0.5 is an integer constant
2301 expression, but (bool) -0.5 is not. Problem reported by Fedor
2302 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2304 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2306 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2307 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2308 Warn about obsolete install-sh files. Remove stray sentence
2309 fragment and fix cross reference.
2310 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2311 install -d; this undoes the 2006-05-10 change.
2312 (MKDIR_P): Mark with AN_MAKEVAR.
2313 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2314 that we don't require $INSTALL to be thread-safe. Move comments
2315 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2316 of AC_PROG_INSTALL. Output a message saying that we're checking
2317 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2318 MKDIR_P instead of AC_SUBST.
2319 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2320 Special magic for MKDIR_P, too.
2321 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2322 a dnl.
2323 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2325 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2327 Sync from Automake, as follows:
2329 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2330 * config/install-sh: Initialize IFS, so field splitting isn't
2331 turned off later.
2332 * config/mkinstalldirs: Likewise.
2333 * config/missing: Remove superfluous quotes. Replace all uses of
2334 `[' by `test', for consistency, and for..
2335 * config/missing (sed_minuso, sed_output): New variables.
2336 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2337 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2338 Fixes `missing' to detect `--output' for help2man. Fixes
2339 PR automake/483. Report by Dennis J. Linse.
2340 (autom4te): Document in `missing --help'.
2342 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2344 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2345 * config/install-sh: Don't use 'path' to talk about file names,
2346 as per GNU coding standards. Close a race condition reported by Ralf
2347 Wildenhues and Stepan Kasal. There is still a race condition
2348 on hosts that predate Posix 1003.1-1992, but we can't help this.
2349 Don't mishandle weird characters like space on pre-Posix hosts.
2350 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2351 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2352 AC_PROG_MKDIR_P from AS_MKDIR_P.
2353 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2354 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2355 earlier editions are not (including Automake 1.8.3).
2356 Do not suggest mkinstalldirs for thread-safety.
2357 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2358 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2359 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2360 presence of special characters and race conditions.
2361 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2362 in Autoconf's name space.
2364 2006-05-10 Bruno Haible <bruno@clisp.org>
2365 and Paul Eggert <eggert@cs.ucla.edu>
2367 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2368 from Automake with minor changes.
2369 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2371 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2373 * config/install-sh: Update to Automake CVS version, as follows:
2374 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2375 * lib/install-sh: Simplify the expr implementation of dirname.
2376 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2377 * lib/install-sh: Handle --, and diagnose unknown options.
2379 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2381 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2382 `./autom4te' to create `./testsuite', since the `all' target
2383 will ensure its presence, but `installcheck' should not create
2384 the uninstalled wrappers.
2386 * tests/torture.at (Unusual Automake input files): Skip if we
2387 detect automake < 1.8.
2389 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2391 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2392 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2393 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2394 * NEWS: Update.
2396 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2398 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2399 munge (multiple) white space and other oddities.
2400 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2401 single quotes in variable assignment.
2402 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2403 and similar failures by adding multiple spaces, tabs, and other
2404 special characters.
2405 Report and different test suggested by Francesco Romani
2406 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2408 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2409 single quotes, we only need to search for single quotes; this
2410 both simplifies the search pattern, and makes us less
2411 susceptible to `echo' variations for arguments not containing
2412 single quotes.
2413 (_AC_ARG_VAR_VALIDATE): Likewise.
2415 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2417 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2418 `$*' and IFS concatenation issue with traditional shells and
2419 bash-2.04. Report by Seanster@Seanster.com.
2421 2006-05-03 Bruno Haible <bruno@clisp.org>
2423 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2424 precisely which Mac OS X versions have the od problem.
2426 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2428 * doc/autoconf.texi: Use @option systematically.
2430 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2431 and Bruno Haible <bruno@clisp.org>
2433 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2434 about 'od'.
2435 (Integer Overflow): Mention the special case of integer division
2436 overflow.
2438 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2440 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2441 traditional shells like the Solaris one that do not use the
2442 first IFS character for assembling `$*'.
2443 Prompted by a related report from autoconf_bug@nro.ca.
2445 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2446 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2448 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2449 Mention more problems with the -e option.
2451 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2453 * NEWS: Typo.
2454 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2456 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2457 in URLs to improve DVI formatted output (requires texinfo 4.6).
2458 (System Services, Systemology, Shellology): Likewise.
2459 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2460 output.
2462 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2463 continuous text.
2464 (Runtime): Fix macro argument names to match description:
2465 `action-if-found' -> `action-if-true' and similarly.
2466 (Obsolete Macros): Likewise.
2467 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2468 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2469 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2471 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2473 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2475 * ChangeLog: Typo.
2476 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2477 DVI output.
2479 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>

2482 /bin/sh set unsorted output.
2483 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2484 * tests/local.at: Likewise.
2486 2006-04-26 Paul Eggert <eggert@cs.ucla.edu>
2488 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2489 (Integer Overflow, Null Pointers, Buffer Overruns):
2490 (Floating Point Portability, Exiting Portably): New sections.
2491 (Writing Test Programs): Fix some langauge. Recommend exiting
2492 with status 1, not merely nonzero. Clarify exit declaration.
2493 (Run Time): Move C exit status stuff to new Exiting Portably section.
2494 (Systemology): Mention Posix and levenez. Update v7 reference.
2495 (Portable Shell): Mention the Posix shell.
2497 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2499 * bin/autoconf.as (me): Replace by as_me.
2501 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2503 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2504 since as_me isn't set yet.
2506 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2508 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2509 a few minor bugs in this area.
2511 * doc/autoconf.texi (Programming in M4sh): Comment out the
2512 documentation of AS_BASENAME, for now.
2513 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2514 (Limitations of Builtins) <basename>: Do not refer to
2515 AS_BASENAME.
2516 * bin/autoconf.as (me): Don't use AS_BASENAME.
2517 (dir): Remove the unused variable.
2518 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2519 AS_DETECT_REQUIRED. All uses changed.
2520 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2521 All uses changed.
2522 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2523 (AS_BASENAME): Use "basename --" to protect against leading "-".
2524 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2525 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2526 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2527 (_AS_DIRNAME_PREPARE): Likewise.
2528 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2529 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2530 (AS_DIRNAME): Use "dirname --".
2532 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2534 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2535 of "run time" and "run-time" changed to "runtime", for consistency.
2536 * lib/autoconf/fortran.m4: Likewise (in comment).

2538 * lib/autoconf/general.m4: Likewise.
2539 * lib/autoconf/headers.m4: Likewise.
2541 * doc/autoconf.texi (Run Time): Document the exit status situation
2542 with more accuracy and detail.
2544 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2546 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2547 Archive is not officially `GNU' any more. Update URL.
2548 (Defining Directories): Likewise
2549 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2551 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2553 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2554 newline from the `trap' code to finish `config.log'; the NetBSD
2555 /bin/sh resets the exit status after an empty command, as
2556 documented in doc/autoconf.texi.
2557 Reported by Dalibor Topic <robilad@kaffe.org>.
2559 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2561 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2562 Suggested by Bruno Haible.
2564 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2566 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2567 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2568 Instead, just list the shells that we know work.
2569 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2570 changed. Be more cautious about the _cv_ variable.
2571 * tests/tools.at (Syntax of the shell scripts): Check the
2572 _cv_ variable once, at first, to avoid an internal autoconf error
2573 when sh -n does not work.
2575 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2577 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2579 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2581 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2582 use ">&-" since we're only 99.999% sure that this is portable,
2583 and since the MinGW bug is fixed in a different way.
2584 * lib/autotest/general.m4 (AT_INIT): Likewise.
2586 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2588 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2589 before opening config.log, to avoid hitting a bug on MinGW.
2591 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2593 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2594 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2595 This works around a MinGW bug reported by Eric Paire.
2596 Make sure that all writes to the log file append to it,
2597 rather than possibly losing data.
2598 * lib/autotest/general.m4 (AT_INIT): Likewise.
2600 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2602 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2603 description.
2605 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2607 * NEWS: Update.
2609 * configure.ac (AC_INIT): Bump to 2.59d.
2611 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2613 Version 2.59c.
2615 * Makefile.maint (news-date-check): Do not require a leading `*'
2616 before the release date in NEWS.
2618 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2619 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2621 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2622 the instantiated file do not contain the string 'datarootdir'
2623 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2624 @mandir@, replace the reference '${datarootdir}' by the value.
2625 * tests/torture.at (datarootdir workaround): New test.
2626 * NEWS: Advertise this temporary fixup.
2627 Based on a patch by Bruno Haible, reported and analyzed by
2628 Paul Eggert and Noah Misch.
2630 2006-04-12 Eric Blake <ebb9@byu.net>
2632 * tests/autotest.at (Debugging a failed test): Fix comment.
2634 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2636 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2637 all the changes since 2006-04-07.
2639 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2641 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2642 succeeded, but `ln -s file dir' failed, take care to remove the
2643 leftover target before the next test, to prevent its spurious
2644 failure; also make sure `ln file dir' works before selecting it.
2645 Thanks to Keith Marshall for pointing this out.
2646 * THANKS: Update.
2648 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2649 assignments in `at_debug_args', so that we put them correctly
2650 in the `run' script.
2651 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2652 Reported by Eric Blake.
2654 2006-04-11 Eric Blake <ebb9@byu.net>
2656 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2657 top-level tests after micro-suite has been run. Used in...
2658 (Debugging a successful test, Debugging script and environment),
2659 (Debugging a failed test): ...these new tests. The first of these
2660 is fixed by...
2661 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2662 macro, split out from...
2663 (AT_INIT): ...here, so that using -d also generates a run script.
2664 Document that -d inhibits top-level logging.
2665 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2666 inhibits top-level logging; debug scripts are created.
2668 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2669 check.
2670 * tests/autotest.at (Empty test, Empty check): New test to check it.
2672 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2673 from gcc.
2675 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2677 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2678 the files if a problem appears. Make the empty *.at files
2679 read-only, too. Proposed by Ralf Wildenhues.
2681 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2683 * config/Makefile.am: Add comment to force updated Makefile.in.
2685 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2686 space only patch to this file, this patch causes the Makefile.in
2687 files that include freeze.mk to be updated, and thus have a
2688 newer time stamp again, which in turn makes a pristine CVS
2689 checkout have correct time stamps.
2691 * Makefile.maint (cvs-sv): New macro, to be used..
2692 (config.guess-url_prefix, config.sub-url_prefix)
2693 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2694 point to CVS text checkout of Gnulib files.
2695 (copyright-check): Bump current year.
2696 (announcement): Do not hard-wire `./announce-gen'.
2697 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2698 correctly.
2699 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2700 `chmod +x'.
2701 (wget_files): Update config.guess, config.sub, texinfo.tex by
2702 `wget-update', now that their URLs work again.
2704 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2706 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2707 Problem noted by Paul D. Smith.
2709 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2711 * doc/autoconf.texi: Remove unused words from word list.
2712 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2713 .x-sc_trailing_space: New files.
2715 * doc/standards.texi: Sync from gnulib.
2717 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2718 `LIBOBJDIR' as experimental.
2720 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2721 with a target directory; it's internally implemented as `cp'
2722 anyway, but since Autoconf advertises the possibility to use
2723 a target directory when LN_S is `ln -s', we need to find out.
2724 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2725 analyzed by Keith Marshall <keith.marshall@total.com>.
2727 * THANKS: Update.
2729 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2731 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2732 confdefs.h as-is. In general, if it has backslash-newline or the
2733 like, then it doesn't work either to sort or to remove empty
2734 lines.

2745 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2747 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2748 apostrophe within a single-quoted string, as this is the usual
2749 tradition and is easier to read than '"'"'. Don't rely on the
2750 shell treating "$/" like '$/'. Use a more-consistent indenting
2751 style for the trap.
2753 2006-04-09 Eric Blake <ebb9@byu.net>
2755 * tests/autotest.at (Backquote command substitution),
2756 (Multiline backquote command substitution): Remove mistaken
2757 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2758 applied...
2759 (Parenthetical command substitution, Multiline parenthetical
2760 command substitution): here.

2795 AC_TYPE_UINTMAX_T, AC_TYPE_UINTPTR_T, AC_TYPE_UNSIGNED_LONG_LONG_INT.
2796 (C Compiler): Move AC_C_LONG_DOUBLE to ...
2797 (Obsolete Macros): here. Under AC_LONG_DOUBLE, mention
2798 AC_TYPE_LONG_DOUBLE or AC_TYPE_LONG_DOUBLE_WIDER instead.

2819 New macros.
2821 * tests/mktests.sh (ac_exclude_list, au_exclude_list): Do not

2837 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2839 Revert the patch from 2006-04-01 and only improve
2840 _AS_DETECT_BETTER_SHELL:
2842 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Do not optimize; do not
2843 skip nonexistent directories.
2844 (_AS_DETECT_BETTER_SHELL): The optimization is moved here--try
2845 only shell candidates which exist.
2846 (AS_UNAME): No need to give three parameters to _AS_PATH_WALK.
2847 * lib/autotest/general.m4 (AT_INIT): No need to give three
2848 parameters to _AS_PATH_WALK.
2850 2006-04-07 Stepan Kasal <kasal@ucw.cz>,
2851 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2853 * bin/autoupdate.in (handle_autoconf_patches): Change the way we
2854 distinguish m4sugar macros.
2855 * tests/tools.at (autoupdating with aclocal and m4_include):
2856 New test. Bug reported by Gary V. Vaughan <gary@gnu.org>,
2857 test case by Noah Misch <noah@cs.caltech.edu>.
2859 2006-04-07 Stepan Kasal <kasal@ucw.cz>
2861 Revert my change from 2006-03-17, in other words:
2862 * lib/m4sugar/m4sh.m4 (AS_BOURNE_COMPATIBLE): Insert BIN_SH=xpg4
2863 and DUALCASE=1.
2864 (AS_SHELL_SANITIZE): Remove DUALCASE=1.
2865 * doc/autoconf.texi (Special Shell Variables) <BIN_SH>: Say that
2866 it is set.
2868 2006-04-07 Eric Blake <ebb9@byu.net>
2870 * doc/autoconf.texi (Programming in M4sh): Document that
2871 AS_MKDIR_P exits the script on failure.
2872 * lib/autotest/general.m4: Remove redundant AS_ERROR.
2874 2006-04-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2876 * config/elisp-comp, config/install-sh, config/mdate-sh,
2877 config/missing, config/mkinstalldirs: Sync from Automake.

2893 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2895 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2896 whether `set' quotes correctly: redirect stderr of the tested
2897 `set', and use a subshell, for Ultrix; use `sed' instead of
2898 `grep' for zsh `set' which may write binary output; match only
2899 at the beginning of a line, to avoid false positives.
2900 In order to avoid false positives by unrelated variables with
2901 multiline content, put the dump algorithm in a subshell and
2902 unset all variables containing newlines (except some which are
2903 special to the shell). Warn about cache variables that are
2904 unset.
2906 2006-04-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2908 * config/config.guess, config/config.sub, config/texinfo.tex:

2917 (AC_SEARCH_LIBS, AC_REPLACE_FUNCS): Need an argument.
2918 (AC_LINKER_OPTION): Remove (renamed to _AC_LINKER_OPTION).
2919 (AC_LIST_MEMBER_OF): Likewise (renamed to _AC_LIST_MEMBER_IF).
2920 (AC_LINK_FILES): Obsoleted since (and thus AU_DEFUN'ed).
2922 * doc/autoconf.texi (Shell Substitutions): Mention the MSYS
2923 shell issue with double-quoted command substitutions of native
2924 commands.
2925 Reported to MSYS by Mark Cave-Ayland, to Autoconf by Keith
2926 Marshall.
2928 * Makefile.maint (sc_cast_of_argument_to_free): Do not fail when

2945 * tests/Makefile.am (maintainer-check-posix):
2946 s/POSIXLY_CORRECTLY/POSIXLY_CORRECT/
2948 * lib/autoconf/status.m4 (_AC_CONFIG_FOOS): Append TAGS to
2949 ac_config_<foo>s again, sometimes normalized, sometimes not.
2950 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):
2951 (AC_CONFIG_COMMANDS): Do not do so here.
2952 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2953 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the
2954 2005-07-25 rewrite. Noticed by Noah Misch.
2956 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): Do not define
2957 _AC_PRESERVE_HELP_ORDER, ...
2958 (AC_ARG_ENABLE, AC_ARG_WITH): ... use AC_PROVIDE_IFELSE insetad.
2960 * lib/autoconf/general.m4 (AC_ARG_VAR): Do not use m4_divert_once
2961 inside m4_expand_once; it is redundant.
2963 * lib/autoconf/general.m4 (_AC_INIT_HELP): Remove the broken support
2964 for --help from Cygnus `configure.'
2966 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>
2968 * doc/autoconf.texi (C Compiler): Warn about #error. Follows up
2969 on a patch proposed by Ralf Wildenhues.

2973 * lib/autoconf/status.m4: Replace <space>''<tab> with
2974 <tab><space> where this makes sense.
2976 2006-04-05 Howard Chu <hyc@highlandsun.com> (trivial change)
2977 Noah Misch <noah@cs.caltech.edu>
2979 * lib/autoconf/general.m4 (AC_PRESERVE_HELP_ORDER): New macro.
2980 (AC_ARG_ENABLE, AC_ARG_WITH): Adjust.
2981 * doc/autoconf.texi (Help Formatting): New node.
2982 * NEWS: Announce AC_PRESERVE_HELP_ORDER.
2984 2006-04-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2986 * TODO, config/Makefile.am, lib/freeze.mk, lib/autoconf/c.m4,
2987 lib/autoconf/specific.m4, lib/autoconf/status.m4,
2988 lib/autoconf/types.m4, lib/autotest/general.m4,
2989 tests/mktests.sh, tests/torture.at: White space cleanup:
2990 remove some SPACE before TAB, or add quoting ('' or @&t@).
2992 * NEWS, TODO, bin/autoreconf.in: `filesystem' -> `file system'.

2996 2006-04-05 Eric Blake <ebb9@byu.net>
2998 * lib/autotest/general.m4 (AT_INIT): Prep AT_*_all, so that an
2999 empty test suite works.
3000 * tests/autotest.at (Empty test suite): Remove xfail.
3002 2006-04-05 Noah Misch <noah@cs.caltech.edu>

3005 TAGS to ac_config_<foo>s.
3006 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS): Do so here.
3007 (AC_CONFIG_COMMANDS): Append NAME to ac_config_commands without
3008 normalizing it, consistent it with previous releases.
3009 * tests/torture.at (Macro calls in AC_CONFIG_COMMANDS tags): New test.
3011 2006-04-05 Paul Eggert <eggert@cs.ucla.edu>
3013 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR, AS_DIRNAME_EXPR):
3014 Use simplified args that Eric Blake originally suggested.
3016 2006-04-04 Paul Eggert <eggert@cs.ucla.edu>
3018 * tests/mktests.sh: Don't use 'cat'; just read the files directly.
3019 Prefer 'sort -u' to 'sort | uniq'. Filter data before sorting it.
3020 Use 'comm' rather than N instances of grep; this also fixes a bug
3021 whereby substrings were incorrectly matched, causing us to not
3022 generate tests for AC_F77_NAME_MANGLING and AC_FUNC_LSTAT.
3023 (exclude_list): Exclude empty macros.
3024 (ac_exclude_list): Exclude AC_INCLUDES_DEFAULT.

3029 Switch from grep to awk syntax.
3030 (ac_exclude_script): Renamed from ac_exclude_egrep.

3035 * lib/autoconf/general.m4 (_AC_INIT_HELP): Only `configure.in' evidences
3036 a subdirectory subject to Cygnus `configure'.
3037 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Likewise.
3039 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Omit the bug
3040 report request when we have no AC_PACKAGE_BUGREPORT.
3042 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3044 * THANKS: Update.

3061 (output): Emit AC_CONFIG_SUBDIRS as needed.
3062 * tests/autoscan.at (autoscan): Remove XFAIL.
3064 2006-04-03 Noah Misch <noah@cs.caltech.edu>
3066 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use AC_MSG_NOTICE.
3068 2006-04-03 Eric Blake <ebb9@byu.net>
3070 * THANKS: Add myself.
3072 2006-04-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
3074 * lib/autotest/general.m4 (AT_INIT): Add `at_testdir' to pointer
3075 to log, point to testsuite output tree.
3077 2006-04-02 Paul Eggert <eggert@cs.ucla.edu>
3079 * NEWS: AC_PROG_CC and AC_PROG_CXX no longer declare 'exit'.

3084 Remove; all uses removed.
3085 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN):

3105 Clean up _AC_COMPILER_EXEEXT* macros.
3107 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
3108 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
3109 ac_file to the name of the default output file and call
3110 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3111 initial `rm' of the candidate files...
3112 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
3113 the same list in subsequent `rm' calls, and for the temporary
3114 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
3115 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
3116 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
3117 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
3118 no longer needed) by libtool. Make it a cache check.
3119 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
3120 copied here by mistake.
3121 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
3122 _AC_COMPILER_EXEEXT.
3123 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
3124 _AC_COMPILER_OBJEXT directly.

3896 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3897 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3898 by the function rather than ignoring it.
3899 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3900 comparing its address. Intel's interprocedural optimization was
3901 outsmarting the old heuristic. Problem reported by
3902 Mikulas Patocka.

3919 Stepan Kasal <kasal@ucw.cz>
3921 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3922 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3923 make its content writable before removing it. Remove an errorneous
3924 comment from the end, where the logs of the failed tests are copied
3925 to the main log file.
3927 2005-09-27 Stepan Kasal <kasal@ucw.cz>

3934 problems if the testsuite were running too fast.
3936 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3938 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h

3950 suggested by Ben Elliston. Handle weird characters correctly.
3952 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3954 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3955 calls, so that the final expansion of this macro is shorter.
3956 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3957 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3958 the cleanup there. Use AS_VAR_* macros, to be more general.
3959 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
3961 * lib/autoconf/general.m4: Use AS_IF where appropriate.
3963 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

3981 2005-08-26 Stepan Kasal <kasal@ucw.cz>
3983 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
3984 in the example. Reported by Bruno Haible.
3985 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
3986 "if $undefined_var;" succeeds with my shell.
3988 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
3989 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
3990 but change the m4_divert_text to m4_divert_once.

4000 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4001 some evil values and relying on the fact that $* concatenates the
4002 parameters by the first character from IFS.
4004 2005-08-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
4005 Stepan Kasal <kasal@ucw.cz>
4007 * lib/autoconf/status.m4 (_AC_CONFIG_REGISTER_DEST): When the
4008 first header appears, define AH_HEADER.
4009 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4010 Update limitations about when to call AC_CONFIG_HEADERS.
4011 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4012 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4013 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4014 ``Configuration Actions''; fix their index entries.
4016 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4017 options correctly. Process N-M as M-N if M is smaller than N.
4018 Process ranges correctly so that N-N will run only N.
4019 Sort and uniquify the tests that will be run. If there is more
4020 than one test, reinsert the banners for the tests.

4026 before passing the macro name to AH_TEMPLATE.
4028 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): config.status
4029 now opens log after option processing; in particular, --version
4030 and --help do not touch config.log.

4047 Prepend to LIBS, not append, in examples.
4049 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4051 When building in place, set srcdir="."; suggested by Tim Van Holder.
4053 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4054 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4055 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4056 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."

4068 2005-08-12 Stepan Kasal <kasal@ucw.cz>
4070 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4071 add "2>&1"; gzip 1.2.4 prints help on stderr.
4073 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4075 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4076 was pushdef'ed twice while popped only once. Push it only once.
4077 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4079 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4081 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now
4082 prefixed by mere "===", not "configure: === ".
4084 2005-07-25 Paul Eggert <eggert@cs.ucla.edu>
4086 * Makefile.maint: Update from Bison.
4088 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4089 "<tab>" in comment, so that the point is understandable.
4091 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4093 Rewrite substantial part of lib/autoconf/status.m4.
4094 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4095 and CONFIG_COMMANDS are not processed in four separate loops.
4096 Instead, there is one main loop. This alows that the common code
4097 is expanded only once, thus config.status (and configure) is smaller.
4099 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4100 the AC_LIST_FILES and cousins macros are no longer used.
4102 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4103 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4104 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4105 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4106 contain the initialization, nor the for loop, nor the associated
4107 commands; all these go to ...
4108 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4109 _AC_OUTPUT_CONFIG_STATUS.
4110 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4111 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4112 (_AC_OUTPUT_FILE): The creation of the sed script ...
4113 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4114 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4115 _AC_OUTPUT_MAIN_LOOP.
4116 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4117 _AC_CONFIG_COMMANDS): Use ...
4118 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4119 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4120 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4121 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4122 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4123 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4124 ... new macros.
4125 (_AC_CONFIG_UNIQUE): Update.
4126 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4127 Replaced by this ...
4128 (_AC_LIST_TAGS): ... new common macro.
4129 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4130 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4131 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4132 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4133 this didn't belong to the `config commands' section.
4134 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4135 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4136 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4137 to the `config commands' section either.
4138 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4139 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4141 ... and many changes to the comments nearby.
4143 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4144 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4145 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4146 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4147 (#define header templates): The comment at the top of the generated
4148 header now includes the name(s) of the source file(s).
4150 Several unrelated small changes:
4152 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4153 parameter to AC_DIAGNOSE.
4154 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4155 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages
4156 with autoupdate; use m4_define_default inside AU_DEFUNed AC_LINK_FILES.
4157 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4158 with AU::AC_OUTPUT.
4159 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code
4160 in AC_OUTPUT doesn't double-quote it either.
4161 * tests/tools.at (autoupdate): AU::AC_OUTPUT no longer double-quotes the
4162 parameters.
4164 2005-07-10 Stepan Kasal <kasal@ucw.cz>
4166 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Document which
4167 versions of Portland Group compiler produce single- and double-quoted
4168 -cmdline argument. Reported by Steven G. Johnson <stevenj@fftw.org>
4169 and Ole Holm Nielsen <Ole.H.Nielsen@fysik.dtu.dk>.
4171 2005-07-07 Paul Eggert <eggert@cs.ucla.edu>
4173 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4174 This is a corrected version of yesterday's patch.
4176 2005-07-07 Stepan Kasal <kasal@ucw.cz>
4178 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Report the full
4179 path, too; insert a "===" to emphasize the line.

4182 ac_cv_build_alias to ac_build_alias.
4183 (AC_CANONICAL_HOST, AC_CANONICAL_TARGET): Simplify.
4185 On 2005-02-24, an unintentional AC_SUBST([CC]) was introduced; this
4186 change eliminates it. Problem reported by Alexandre Duret-Lutz.
4187 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Move the AC_SUBST ...
4188 (AC_ARG_VAR): ... here.
4189 (_AC_INIT_PREPARE): Call AC_SUBST for build_alias, host_alias and
4190 target_alias.
4192 Keep a list of all precious variables and process them with one simple
4193 for loop, instead of expanding all commands, or, OTOH, complicated
4194 processing of output of "set".
4195 * lib/autoconf/general.m4 (_AC_ARG_VAR_PRECIOUS): Acumulate the
4196 variable names in new macro...
4197 (_AC_PRECIOUS_VARS): ... which will be assigned to ac_precious_vars.
4198 (_AC_ARG_VAR_STORE): New macro which writes to diversion PARSE_ARGS
4199 a loop to assign all ac_env_* and ac_cv_env_* variables.
4200 (_AC_ARG_VAR_VALIDATE): Use shell variable ac_precious_vars, divert
4201 to INIT_PREPARE.
4202 (_AC_INIT_DEFAULTS): At the end, if _AC_PRECIOUS_VARS is set, assign
4203 its value to shell variable ac_precious_vars and call
4204 _AC_ARG_VAR_STORE and _AC_ARG_VAR_VALIDATE.
4205 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Don't call
4206 _AC_ARG_VAR_VALIDATE.
4208 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Move AC_LANG_PUSH(C)
4209 and the AC_SUBSTs ...
4210 (AC_INIT): ... here.
4212 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Changed the title of
4213 the ac_subst_files section in config.log.
4215 * tests/local.at (AT_CONFIG_CMP): Revert Paul's previous change.

4224 Fix problems reported by Nicolas Joly.
4225 * tests/base.at (Input/Output): Ignore 'loading site script' chatter.
4226 * tests/local.at (AT_CONFIG_CMP): Ignore lines like "LIBS=''" too.
4227 They are generated by the Tru64 v5.1B shell.
4229 2005-07-05 Stepan Kasal <kasal@ucw.cz>
4231 Fix my changes from 2005-07-01; reported by Noah Misch.
4232 * lib/autoconf/status.m4 (_AC_CONFIG_DEPENDENCIES): Fix the
4233 description, the macro now accepts only a single tag.
4234 (_AC_CONFIG_UNIQUE): Likewise; s/AC_File/[$1]/
4236 Fix cases when the varsions of Autoconf and Autotest don't match.
4237 Reported by Noah Misch.
4238 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Set also
4239 at_top_builddir, for compatibility with older autotest.
4240 * lib/autotest/general.m4 (AT_INIT): If at_top_build_prefix
4241 is not set, use at_top_builddir, for compatibility with older
4242 versions of autoconf.
4244 2005-07-04 Paul Eggert <eggert@cs.ucla.edu>
4246 * bin/autom4te.in ($m4): Catch usages like --nesting-limit=2048.
4247 Problem reported by Patrick Welche.
4249 2005-07-03 Paul Eggert <eggert@cs.ucla.edu>
4251 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use &, not |, in
4252 sed substitution command, so that we allow | in program prefixes
4253 and program suffixes. (& is a problem anyway; we're not fixing
4254 that here.)
4255 * lib/autoconf/status.m4 (AC_CONFIG_FILES): Likewise, for
4256 configure_input, top_builddir, srcdir, etc.
4257 * lib/autotest/general.m4 (AT_INIT): Likewise, for
4258 PATH_SEPARATOR in AUTOTEST_PATH.
4260 2005-07-02 Alexandre Duret-Lutz <adl@gnu.org>
4262 * lib/autoconf/general.m4 (AC_SITE_LOAD): Rewrite the
4263 for loop over config.site files using `set', to allow
4264 directory names containing IFS characters.

4268 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for
4269 directories with weird names. Apparently some people like living
4270 on the edge. However, improve the test that "pwd" actually does
4271 report a name for the working directory.

4288 (Limitations of Usual Tools) <sed>: Another minor rephrasing.
4290 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Use a here
4291 document to output the default config_* lists to config.status.
4292 Don't recognize option --file, if the functionality is not there.
4293 Likewise for --header; moreover, recognize --he and --h as shortcuts
4294 for --help in that case.
4296 * lib/autoconf/status.m4: Fix the order of the "sections", so that it
4297 matches the order of execution. No code changed.

4318 * lib/autoconf/general.m4 (AC_SUBST_TRACE): New macro, to be traced
4319 instead of AC_SUBST; proposed by Alexandre Duret-Lutz.
4320 (AC_SUBST): Call it.
4321 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Call AC_SUBST_TRACE for
4322 the directory specific variables; but don't call it for configure_input.
4324 2005-06-28 Derek Price <derek@ximbiot.com>
4326 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Reword recent
4327 addition.
4329 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>
4331 * NEWS: Don't worry about spaces in bindir etc. Only srcdir and working
4332 directory have inherent problems with special characters like spaces,
4333 due to limitations in Make syntax. Problem reported by Alexandre
4334 Duret-Lutz.
4335 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Implement the above.

4348 from Justace Clutter.
4349 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Put name of invalid
4350 variable into diagnostic. Make the diagnostic an error, not a warning,
4351 because we really don't support spaces and suchlike in dir names.
4352 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4353 Don't worry about backslashes in srcdir; it can't happen now.
4354 (_AC_INIT_PARSE_ARGS): Allow weird characters in ac_optarg.
4355 Simplify ac_optarg handling.
4356 (_AC_ARG_VAR_VALIDATE): Remove unnecessary and inconsistent quotes.

4364 (AT_CONFIG_CMP): Use sed instead of grep plumbing.
4366 * doc/autoconf.texi (Limitations of Usual Tools) <grep>: Mention
4367 that '\|' is not allowed in BREs; recommend using newline separated
4368 list of patterns instead of multiple -e options.
4370 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Remove an old comment.
4372 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Use AC_SUBST/2.

4378 2005-06-21 Stepan Kasal <kasal@ucw.cz>
4380 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: Document that
4381 b, t, r, w commands require single space, while : cannot have any.
4382 (Special Shell Variables): Fix sed code this in the example.
4383 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Likewise; and fix a typo.
4384 * lib/autotest/general.m4 (AT_ARG_OPTION): Fix typo in the description.
4386 * lib/m4sugar/m4sugar.m4 (m4_split): If the parameter is empty,
4387 expand to the empty list. Don't use two pairs of m4_changequote,
4388 it's not necessary.
4390 2005-06-20 Derek Price <derek@ximbiot.com>
4392 * lib/m4/programs.m4 (AC_PROG_YACC): Declare YACC & YFLAGS precious.
4394 2005-06-17 Paul Eggert <eggert@cs.ucla.edu>
4396 * lib/m4sugar/m4sh.m4 (as_awk_strverscmp): Port to Solaris /bin/awk.
4397 * doc/autoconf.texi:
4398 Don't mention Solaris versions so much, if a
4399 problem is common to all extant versions of Solaris. Say "SunOS
4400 4" instead of "SunOS" for SunOS 4.
4401 (awk): Mention more of the limitations of traditional Awk.
4402 (cat): Don't talk about cat -v.
4404 2005-06-16 Paul Eggert <eggert@cs.ucla.edu>

4409 to be compatible with glibc strverscmp.
4410 * tests/m4sh.at (AS_VERSION_COMPARE): New test.
4412 * doc/autoconf.texi (Limitations of Usual Tools): Mention expr bug
4413 on Mac OS X 10.4 reported by Peter O'Gorman in:

4415 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT):
4416 Use shell builtins rather than 'expr', to work around expr bug.
4418 2005-06-10 Paul Eggert <eggert@cs.ucla.edu>
4420 * doc/autoconf.texi: "filesystem" -> "file system".
4421 "behaviour" -> "behavior".
4422 Warn about \(...\)* in Solaris sed (written by Ralf Menzel).
4423 * lib/autoconf/general.m4: Omit blank after ":" sed command,
4424 as per POSIX.

4434 * lib/m4sugar/m4sh.m4 (AS_VAR_TEST_SET): Work even if $1 contains
4435 quotes and backslashes. Patch from Derek Price.

4440 AS_TR_SH.
4442 2005-06-08 Paul Eggert <eggert@cs.ucla.edu>
4444 * lib/autotest/general.m4 (AT_INIT): Don't accept Solaris 9's diff
4445 -u, since it outputs chatter if the input files are the same.
4446 Problem reported by Ralf Menzel.
4448 2005-06-08 Derek Price <derek@ximbiot.com>
4450 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4451 renaming them since they are about to be redefined anyhow.
4453 2005-06-08 Derek Price <derek@ximbiot.com>
4455 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4456 redefined M4 macros to this node. Document m4_include & m4_sinclude.
4457 Move m4_undefine to alphabetical order.
4459 2005-06-07 Paul Eggert <eggert@cs.ucla.edu>
4461 * README: Recommend GNU M4 1.4.3 or later.
4462 * doc/autoconf.texi (Introduction): Likewise.
4463 Reword to avoid some formatting glitches.
4464 Use "#!/bin/sh", not "#! /bin/sh"; the space isn't needed these days.
4465 Clarify explanation of HP compiler bug.
4466 Redo example output tp match current CVS snapshot.
4467 Use @example.org in email addresses when the examples
4468 might get inadvertently cut-and-pasted into user code.
4469 Remove example of autom4te usage that doesn't seem to work now.
4470 Use modern AC_INIT (except when the example is meant to be
4471 shown with Autoconf 2.13).
4472 Update ksh info for Solaris 9 and later.
4473 KB -> kB.
4474 Modernize description of Automake versions a bit.
4475 Don't claim a future version of Autoconf is near.

4481 follows its own advice about quoting better.
4482 Reword to avoid some formatting glitches.
4483 * doc/installt.exi: Reword to avoid some formatting glitches.
4485 * doc/autoconf.texi (Limitations of Builtins) <case>: Mention
4486 Tru64 ksh pattern matching bug. Reported against Libtool by
4487 Albert Chin <libtool@mlists.thewrittenword.com> and
4488 Nicolas Joly <njoly@pasteur.fr>.
4490 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4492 m4_cdr of one-member list was [[]] (one-member list containing an
4493 empty string) instead of [] (an empty list. Callers were skewed to
4494 match this misbehaviour. As a consequence of this:
4495 - m4_foreach([x], [], [foo]) expanded to `foo', while
4496 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4497 This bug has been fixed:
4499 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4500 expand to an empty string; print error msg if called without
4501 an argument list.
4502 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous
4503 misbehaviour; handle [] and [[]] correctly.
4505 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4507 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Nuke ac_max_here_lines.
4508 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Simplify the sed
4509 scripts created and the loop applying them, use _AC_SED_CMD_LIMIT.
4511 2005-06-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (trivial change)
4513 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4514 swallow records with more than 99 fields.
4515 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4516 parse the long line.
4518 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4520 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot
4521 swallow literals longer than 399. Reported by Ralf Wildenhues.
4522 * lib/autotest/general.m4 (AT_INIT): Pass $at_groups though stdin,
4523 to workaround this limitation.
4525 2005-06-03 Steven G. Johnson <stevenj@alum.mit.edu>
4527 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Find g95 in addition
4528 to gfortran, and make these the first two compiler names
4529 checked (following the general autoconf preference for gcc).
4531 2005-06-03 Stepan Kasal <kasal@ucw.cz>
4533 * tests/Makefile.am (check_SCRIPTS): Set to $(wrappers).
4534 (DISTCLEANFILES): Remove $(check_SCRIPTS).
4535 (testsuite): Make sure autotest.m4f is up-to-date before using it.
4537 2005-06-02 Paul Eggert <eggert@cs.ucla.edu>
4539 * lib/autotest/general.m4 (AT_INIT): Don't create a regular
4540 expression of unbounded size when processing the --list
4541 option. This runs afoul of a limit of 399 bytes per regular
4542 expression on AIX. Problem reported by Ralf Wildenhues.
4544 2005-06-01 Paul Eggert <eggert@cs.ucla.edu>
4546 * NEWS: Note yesterday's changes to AC_SUBST and AC_SUBST_FILE.
4547 * doc/autoconf.texi (Particular Headers): Reword example
4548 for multiline stdbool replacement.
4549 (Setting Output Variables): Reword text a bit. Don't
4550 give all the details about |#_!!_#|.
4551 Reword description of line replacement.
4553 2005-05-31 Dan Manthey <dan_manthey@partech.com>
4555 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Output variables may
4556 now contain newlines, and substituted files must be referenced on
4557 a line alone; the sed scripts to substitute them are now very
4558 different.
4559 (_AC_SED_CMD_LIMIT): Added; single place to store limit on how many
4560 commands can be put in a sed script portably.
4561 * doc/autoconf.texi (Setting Output Variables): Document above
4562 changes. (Particular Header Checks) <AC_HEADER_STDBOOL>: Give exaple
4563 use of multiline substitution.
4564 * tests/torture.at: No longer expect substitution of newline to fail.
4566 2005-05-27 Paul Eggert <eggert@cs.ucla.edu>
4568 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Fix diagnostics.
4569 From Ralf Menzel (trivial change).
4571 2005-05-25 Paul Eggert <eggert@cs.ucla.edu>
4573 * tests/local.at: Don't attempt to check for negated character
4574 classes in shell scripts. The test was too brittle.
4576 2005-05-25 Stepan Kasal <kasal@ucw.cz>
4578 * bin/autoconf.as: Don't use "shift 2"; it's not portable enough.
4579 * doc/autoconf.texi (Limitations of Builtins): Document this
4580 limitation.
4582 2005-05-24 Stepan Kasal <kasal@ucw.cz>
4584 * lib/m4sugar/m4sh.m4 (_AS_ECHO_LOG): New macro to factor out
4585 common code; used in many places in the tree.
4586 (AS_ESCAPE): Make the pattern a bit simpler; use \& insetad of \1.
4587 (_AS_ECHO_UNQUOTED): Move the macro lower; no code change.
4589 * lib/m4sugar/m4sugar.m4 (m4_ifset): Use m4_ifval.
4591 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Merge the two error
4592 messages when ac_unique_file is not found.
4593 (AC_CONFIG_MACRO_DIR): Simplify the `if' at the end.
4594 (AC_MSG_CHECKING, AC_MSG_RESULT): Put braces around the two echo
4595 commands, for consistency with AC_MSG_ERROR and such.
4597 * bin/autoconf.as: Make more use of "shift 2" in option processing.
4599 * bin/Makefile.am: Merge the two rules for creating scripts.
4601 2005-05-23 Stepan Kasal <kasal@ucw.cz>
4603 * lib/autoconf/general.m4 (AC_MSG_RESULT_UNQUOTED): Make
4604 obsolete; it was never documented.
4605 (AC_CACHE_CHECK): Use AC_MSG_RESULT instead.
4607 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4609 * NEWS: @top_builddir@ is now a dirname, ac_top_builddir will follow.
4610 * lib/autoconf/status.m4 (_AC_SRCDIRS): Rename ...
4611 (ac_top_builddir): ... this ...
4612 (ac_top_build_prefix): ... to this; the old name is also kept, for
4613 backward compatibility.
4614 (ac_top_builddir_sub): New variable, without the trailing slash,
4615 always nonempty.
4616 (_AC_OUTPUT_FILES): s/@top_builddir@/$ac_top_builddir_sub/
4617 * doc/autoconf.texi (Configuration Actions): Rename
4618 ac_top_builddir to ac_top_build_prefix.
4619 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Rename
4620 at_top_builddir to at_top_build_prefix.
4621 * lib/autotest/general.m4 (AT_INIT): Likewise.
4623 2005-05-20 Stepan Kasal <kasal@ucw.cz>
4625 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4626 of confdefs.h .
4628 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4630 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4631 argument to m4_foreach. I guess it was necessary in the past,
4632 but I think it's a no-op now.
4634 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4636 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4637 ``cat <<_ACEOF'' commands to one.
4638 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4639 * lib/autoconf/status.m4: On various places, use expr instead of
4640 ``echo|sed.''
4641 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4642 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4643 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4644 a range.
4645 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4646 the wrong patterns between ``case'' and ``esac.'' The previous
4647 code had false positives.
4649 2005-05-14 Alexandre Duret-Lutz <adl@gnu.org>
4651 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA): Prepend ${LIBOBJDIR},
4652 as on 2005-05-02.
4653 * doc/autoconf.texi (Particular Functions) <AC_FUNC_ALLOCA>:
4654 Mention LIBOBJDIR.

4694 2005-05-13 Stepan Kasal <kasal@ucw.cz>
4696 * lib/autoconf/general.m4 (AC_CONFIG_LIBOBJ_DIR): Remove the broken
4697 check.
4698 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Halt with error if we don't get
4699 enough arguments, similarly as in m4_bpatsubsts.
4701 2005-05-12 Stepan Kasal <kasal@ucw.cz>
4703 * lib/autoconf/status.m4 (_AC_SRCDIRS): Simplify the computation
4704 of absolute paths.
4706 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4708 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4709 for absolute directory names in one loop.
4710 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle
4711 abbreviations of --version and --debug.
4713 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4715 * doc/autoconf.texi (Autoconf Language): Be more precise about
4716 quoting rules. Problems noted by Stepan Kasal.
4717 Also, throughout this document, be more careful about white space.
4718 "blank", "white space", and "space" all have different meanings
4719 and we should be careful to say what we mean.
4721 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4723 Fix C++ related problems reported by Werner Lemberg.
4724 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.
4725 * lib/autoconf/c.m4 (AC_LANG(C++)): Set ac_ext to .cpp, not .cc.
4726 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4727 avoid problems with C++ and throw.
4728 * tests/compile.at: .cpp, not .cc.
4730 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4732 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4734 * doc/autoconf.texi (Generic Functions): Typos.
4736 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4738 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4739 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4740 set by latest automake.
4742 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4744 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4745 outputs 0 on GNU/Linux these days.
4747 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4749 * doc/autoconf.texi (Autoconf Language): Add more description
4750 about quoting heuristics.
4751 (Limitations of Builtins): Describe "set -" problems.
4753 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4755 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4756 not newline.
4758 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4759 by AC_DEFINE; it was a mistake.
4760 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4762 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4764 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4766 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4768 * doc/autoconf.texi (External Software): Quadrigraphs are not
4769 processed correctly in AS_HELP_STRING; avoid this in the examples.
4770 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4771 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4772 comment and reduce m4_default([foo], []) to [foo].
4773 (m4_strip): Update the explanation.
4775 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4777 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4778 Remove core.conftest.* too; it's generated by Tru64 5.1.
4779 Problem reported by Jennis Pruett.
4780 * lib/autoconf/functions.m4
4781 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4782 Don't bother to remove core files; AC_RUN_IFELSE should do that
4783 for you.
4785 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4787 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
4789 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
4791 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
4792 Report from Horst Wente.
4794 2005-04-15 Stepan Kasal <kasal@ucw.cz>
4796 * lib/autoconf/general.m4 (_AC_ARG_VAR_VALIDATE): Fixed a typo in
4797 the comment.
4799 2005-04-14 Gregorio Guidi <greg_g@gentoo.org>
4801 * doc/autoconf.texi (External Software, Package Options): Add
4802 examples showing how to implement --with-* and --enable-* options.
4804 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4806 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4807 as well as configure.in. Problem reported by Gregorio Guidi.
4809 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4811 * doc/autoconf.texi (Particular Functions): Use gnulib's current
4812 pattern for alloca snippet.
4814 2005-04-04 Stepan Kasal <kasal@ucw.cz>
4816 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): Fix a typo.
4818 2005-04-01 Stepan Kasal <kasal@ucw.cz>

4822 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4824 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4825 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4827 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4829 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4830 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4831 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4832 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4833 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4835 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4837 * NEWS: The configure command now warns you if you attempt to use
4838 a directory whose name contains a special character like space,
4839 newline, or "\".
4840 * doc/autoconf.texi (Installation Directory Variables): Allow
4841 "," in file names. Do not use \@; it's not a portable regexp.
4842 * bin/Makefile.am (edit): Likewise.
4843 * lib/Makefile.am (edit): Likewise.
4844 * tests/Makefile.am (edit): Likewise.
4845 * tests/semantics.at: Likewise.
4846 * tests/torture.at: Likewise.
4847 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4848 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4849 * doc/autoconf.texi (File System Conventions): Warn about
4850 unportable file names.
4851 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4852 (AC_INIT): Use it.
4853 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4854 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4855 ac_pwd, and quote srcdir.
4856 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4858 * doc/autoconf.texi: Fix some systematic formatting problems.
4859 ".)" needs a following @: if not at the end of a sentence, and
4860 similarly for "!)". "etc." should be preceded by a comma.
4861 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4863 2005-03-22 Bruno Haible <bruno@clisp.org>
4865 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4866 argument is often called 'build-aux'.
4868 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4870 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4871 macro AC_TRY_LINK is obsolete.
4872 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4873 `AC_CONFIG_FILES'.
4875 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4877 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4878 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4879 from a Common Lisp's `cl'.
4880 (AC_PROG_CXX): Behave according to the documentation: don't
4881 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4882 make the variable CCC precious; use `cl.exe', not `cl'.
4884 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4885 Alexandre Duret-Lutz <adl@gnu.org>
4887 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4888 /dev/null, as "configure" shouldn't read stdin, and this insulates
4889 us from problems (e.g., when testing for "cl"). Also, do this
4890 redirection before invoking "hostname" or "uname", and keep the
4891 original input stream available via...
4892 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4893 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4894 bother with "</dev/null" since it's now done at the top of
4895 'configure'.
4896 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4897 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4898 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4899 * doc/autoconf.texi (File Descriptor Macros): New section.
4900 (Printing Messages): Mention it.
4901 * tests/base.at (Input/Output): New test.
4903 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4905 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4906 newline if neither \c nor -n work, as that would output two
4907 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4909 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4911 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4912 This causes that any required macros inside will get before the if.
4913 * doc/autoconf.texi (autom4te.cache): A typo.
4915 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4917 Undo previous change, except keep the change to
4918 lib/autoconf/programs.m4 that replaced grep with shell
4919 pattern-matching. This is because net-snmp configure reads stdin.
4920 Reported by Noah Misch.
4922 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4924 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4925 from /dev/null, as "configure" shouldn't read stdin, and this
4926 insulates us from problems (e.g., when testing for "cl").
4927 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4928 before invoking "hostname" or "uname".
4929 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4930 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4931 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4932 "</dev/null" since it's now done at the top of 'configure'.
4933 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4934 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4935 Also, replace grep with shell pattern-matching, to save a process.
4937 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4939 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4940 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4941 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4942 compiler.
4944 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4946 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4947 grep -q isn't portable. Improve grep -s explanation.
4948 Problem reported by Dan Manthey.
4950 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4952 * doc/autoconf.texi (Special Shell Variables): Clarify
4953 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4955 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4957 * doc/autoconf.texi: Use @acronym for DJGPP.
4958 Fix some @code's that should have been @env's, and vice versa.
4959 Sort environment variable names.
4960 Mention that shells no longer inherit IFS.
4961 Don't recommend PATH_SEPARATOR=';' so strongly.

5040 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5042 Try not to generated lines of unlimited length, as POSIX places a
5043 2047-byte limit on line length of portable text files.

5103 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5104 Update the long comment explaining it.
5106 m4_require no longer writes an ``is required by'' line to the
5107 execution stack. It contains only one bit of non-redundant
5108 information: that the macro was required, not called. And even
5109 this bit is useless in most situations: have you ever met a macro
5110 which both calls and requires the same macro?
5112 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5113 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5120 (_m4_require_call): Use it.
5121 * tests/m4sugar.at (m4_require): Expect output without the
5122 ``is required by'' messages.
5124 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>
5126 * doc/autoconf.texi (Limitations of Usual Tools): Recommend X
5127 rather than x for expr.
5129 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT): Avoid subshells when
5130 this is safe.
5131 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): Likewise.

5153 2005-01-21 Paul Eggert <eggert@cs.ucla.edu>
5155 * doc/autoconf.texi (Limitations of Builtins): Clarify that

5158 2005-01-20 Paul Eggert <eggert@cs.ucla.edu>
5160 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5161 Warn about newline stripping in `` and $(). Update Solaris
5162 version to 9.
5163 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5164 X insulates us from future changes to Posix.
5165 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline
5166 stripping.
5168 2005-01-19 Stepan Kasal <kasal@ucw.cz>

5190 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5192 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5214 (_m4_divert_n_stack): New macro; the expansion is
5215 <newline>m4_divert_stack, if m4_divert_stack is defined, and void
5216 otherwise.
5217 (m4_divert, m4_divert_push, m4_divert_pop, m4_init): Use it.
5218 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5219 stored in _m4_divert_diversion or _m4_divert_dump.
5220 (m4_divert_pop): When the parameter is given, compare the symbolic
5221 name with the last diversion pushed on the stack. Previously, the
5222 current diversion was compared with the numeric value of the
5223 diversion given as the parameter.
5224 (m4_require): If the macro hasn't been expanded yet, call ...
5225 (_m4_require_call): this new macro.

5258 * bin/autoreconf.in (autoreconf_current_directory): AM_INIT_AUTOMAKE

5439 autoscan.1, autoupdate.1, ifnames.1, config.guess.1, config.sub.1):
5440 Don't depend on .x file explicitly, since "make" does that for us.
5441 Suggested by Stepan Kasal.
5443 * bin/Makefile.am (MOSTLYCLEANFILES): Renamed from CLEANFILES.
5444 Add *.tmp.
5445 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate,

5504 2004-12-08 Paul Eggert <eggert@cs.ucla.edu>
5506 * lib/mdate-sh: Don't use "set - x`$ls_command /`", as zsh mishandles
5507 the spaces inside $ls_command. Problem reported by Loulou Pouchet in
5508 <http://lists.gnu.org/archive/html/autoconf/2004-12/msg00074.html>.
5509 Don't use "set - x"; plain "set x" is enough, and simplifies debugging.
5511 2004-12-07 Stepan Kasal <kasal@ucw.cz>
5513 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Fix typo in previous

5528 with exactly one parameter.
5530 2004-12-02 Paul Eggert <eggert@cs.ucla.edu>
5532 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5533 "char c = '\200';" rather than "char c = 0x80;" as the
5534 latter doesn't conform to the strict C standard due to
5535 overflow on signed char hosts.
5537 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5538 to -qlanglvl=ansi. We don't want to disable extensions.

5558 Automake (not without Autoconf).
5559 (Introduction): Mention lists.gnu.org.
5560 * BUGS: Don't mention bugs.gnu.org.
5561 Remove mention of ancient libtool compatibility problem.

5596 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5598 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5599 the $1_found variable, don't test whether the file is executable;
5600 Both things are checked ...
5601 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5602 the former ``test -f''.
5603 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Fix a typo.
5605 2004-11-10 Paul Eggert <eggert@cs.ucla.edu>

5638 Problem reported by Stepan Kasal.
5640 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>
5642 Fix problems reported by Andreas Buening in:
5643 http://lists.gnu.org/archive/html/autoconf-patches/2004-04/msg00004.html

5645 in test makefile.
5646 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is

5649 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5651 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5652 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5653 (trivial change). Problem and patch reported by Andrew Church in:
5654 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5656 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>
5658 * doc/autoconf.texi: Give AC_DEFINE and AC_DEFINE_UNQUOTED

5661 Also, fix some minor spacing and punctuation bugs.

5683 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5684 texinfo.tex for now (done by hand now).
5685 * Makefile.maint (wget_files, cvs_files):
5686 Remove ansi2knr.c; nobody uses it.
5687 (ansi2knr.c-url_prefix): Remove.
5688 (cvs-update): Fix test for failure. I don't know why it ever
5689 worked...
5691 * doc/autoconf.texi: Update URLs, some of which went stale.
5692 Use @uref rather than @href.
5694 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5695 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5697 * config/config.guess, config/config.sub, config/elisp-comp,
5698 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5699 doc/fdl.texi, doc/standards.texi: Sync with master copy.
5701 * NEWS, TODO, configure.ac, bin/autoscan.in,
5702 bin/autoupdate.in, bin/ifnames.in, doc/autoconf.texi,
5703 doc/install.texi, lib/Autom4te/Configure_ac.pm,

5707 lib/m4sugar/m4sugar.m4, tests/local.at, tests/m4sh.at,
5708 tests/tools.at, tests/torture.at:
5709 Use "file name" rather than "filename" or "path",
5710 to be consistent with the terminology of the GNU coding standards.
5712 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5714 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5715 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5716 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5717 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5719 More fixes to support spaces in the name of the build directory.
5720 This isn't a complete fix but it's an improvement.
5722 * bin/autoconf.as (autom4te_options): New var.
5723 Use it instead of appending to AUTOM4TE, so that we can allow
5724 spaces in the build directory's absolute name.
5725 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5726 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,

5734 From Ralf Corsepius in:
5735 http://lists.gnu.org/archive/html/autoconf-patches/2004-08/msg00014.html
5737 2004-08-12 Paul Eggert <eggert@cs.ucla.edu>
5739 * doc/autoconf.texi (Function Portability): Document isinf and
5740 and isnan. From a suggestion by Kevin Ryde.
5742 * lib/Autom4te/General.pm (END): Return correct exit status even
5743 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5745 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5747 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5748 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5749 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5751 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5753 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5754 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5755 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5756 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5757 * lib/autom4te.in (Automake-preselections): Preselect
5758 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5760 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5762 * lib/autom4te.in (Automake-preselections): Preselect
5763 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5764 trace them.
5766 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>
5768 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Set BIN_SH, for
5769 Tru64.
5770 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5771 Document problem with "`""`" in pdksh POSIX mode.
5773 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5775 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5776 with pdksh, too. Problem reported by Patrick Welche via
5777 Gary V. Vaughan.
5778 * doc/autoconf.texi (Shellology): Note that set -o posix is
5779 useful for pkdsh, too.
5781 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5783 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5784 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5785 Don't fail if ENV or BASH_ENV is readonly.
5786 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5787 etc. are read only. Problem reported by Ludovic Courtes.
5789 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5791 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5792 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5793 (trivial change)
5795 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5797 * doc/autoconf.texi (File System Conventions): Warn about
5798 names like "aux". Problem reported by Eric Blake.
5800 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5801 by zero instead of array size, so that we can use any arithmetic
5802 constant expression (instead of requiring an integer constant
5803 expression). This allows us to test expressions like DBL_MAX <
5804 LDBL_MAX, which didn't conform to the C standard using the old
5805 method.
5806 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5807 now that we can do floating-point tests at compile time.
5809 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5811 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5812 and LDBL_EPSILON, as the resulting expression isn't an
5813 integer constant expression and violates the C standard.
5814 Problem reported by Nelson H. F. Beebe. Also, check
5815 for "L" suffix, and check that long double doesn't have
5816 worse range or precision than double, that mixed-mode
5817 arithmetic doesn't generate a diagnostic, that double
5818 constants fit in long double.
5820 2004-06-03 Kevin Ryde <user42@zip.com.au>
5822 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5823 malloc(0) and realloc(NULL,size).
5825 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5826 Bob Proulx.
5828 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5830 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5831 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5832 by Jim Meyering.
5834 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5836 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5837 can be rewritten using if-then-else. Suggested by Bruno Haible.
5839 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5841 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5842 Problem reported by Stepan Kasal.
5844 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5846 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5847 change). Patch reported by Ralf Wildenhues in
5848 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5850 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5851 function F exists if the compiler and linker let you compile an
5852 expression like (F != 0). Recent versions of GCC optimize away
5853 the reference to F in that case, since every function address must
5854 be nonzero, so the link succeeds even if F does not exist.
5855 Problem reported by Manu in
5856 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5858 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5859 "Unix". Many uses changed.
5860 (Limitations of Builtins): Explain better why the ! command isn't
5861 portable.
5863 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>
5865 * lib/autom4te.in (Automake-preselections): Preselect
5866 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5868 2004-05-19 Kevin Ryde <user42@zip.com.au>
5870 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5871 referencing AC_FUNC_STRERROR_R.
5873 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5874 note pessimistic assumption when cross compiling.
5876 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5878 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5879 (until 2004) invoked subcommands with sh -e, contra POSIX.
5880 Reported by Kevin Ryde.
5882 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5884 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5885 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5886 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5887 `test -f " /usr/bin/grep"', which _always_ failed.
5888 (AC_PROG_SED): Ditto bogus PATH fix.
5889 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5890 requires that grep correctly supports _multiple_ `-e' options, rather
5891 than stating only that grep should accept `-e'.
5893 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5895 Port to C99, which requires that 'exit' be declared.
5897 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5898 to ensure that stdlib.h is included.
5899 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5900 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5901 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5902 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5903 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5904 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5905 when using 'exit' in a test; C99 requires that 'exit' be declared.
5907 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5909 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5910 now prefers 'grep' implementations that accept -e.
5911 (Limitations of Usual Tools): Describe problems of traditional
5912 egrep and fgrep with long input lines, and of traditional grep
5913 with -e.
5914 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5915 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5916 All callers changed. Append /usr/xpg4/bin to the PATH, for
5917 Solaris.
5918 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5919 the user with complaints about multiple -e options.
5920 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5921 Define it with AC_PROG_GREP.
5922 * configure.ac (AC_PROG_GREP): Add.
5923 * lib/freeze.mk (GREP): New macro.
5925 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5927 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5928 a possible candidate only after all others fail, rather than
5929 consulting it first. This improves backward compatibility by
5930 better reflecting the way shell selection occurred in previous
5931 versions of Autoconf, and should help to avoid triggering latent
5932 problems in other packages, such as the one in Automake where zsh
5933 is not handled robustly:
5934 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5935 Although it is not Autoconf's responsibility to work around
5936 problems in Automake, it nevertheless makes sense to avoid
5937 introducing unnecessary incompatibilites.
5939 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5940 Gary V. Vaughan <gary@gnu.org>
5942 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5943 how deeply nested we are when a suitable tool is found, set the
5944 ac_path_TOOL_found flag.
5945 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5946 nested we are in this macro. Break out of all 3 nested loops if
5947 ac_path_TOOL_found is set.
5949 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5951 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5952 of the _AS_PATH_WALK loop too if GNU flavor is found.
5954 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5956 * doc/autoconf.texi (Limitations of Make): Update documentation
5957 for `$<'. New entry `Long lines', based on a report from Simon
5958 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
5959 paragraph about DJGPP, based on a mail from Richard Dawe.
5961 2004-04-20 Paul Eggert <eggert@twinsun.com>
5963 * tests/c.at (C keywords): Don't assume that GCC supports
5964 "restrict" and "inline", as sufficiently-old GCC versions do not
5965 (also, GCC configured to be in pedantic C89 mode does not).
5966 Problem reported by Sumit Pandya in:
5967 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
5969 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
5970 consider -g to work if it generates warnings when plain compiles
5971 don't. Problem reported by Braden McDaniel in:
5972 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
5974 * doc/autoconf.texi (Slashes): New section, to document a problem
5975 reported by Jim Meyering in:
5976 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
5978 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
5979 linker output files before linking, to work around IRIX 6 linker bug.
5980 Problem reported by Rainer Orth in:
5981 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
5983 2004-04-20 Gary V. Vaughan <gary@gnu.org>
5985 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
5986 best tool so far counter rely on the tool path variable name to
5987 avoid checks for one tool being affected by the results of running
5988 the length check on a previous tool.
5990 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional
5991 match expression argument, as different greps have different
5992 regular expression flavours.
5993 (AC_PROG_FGREP): Pass 'FGREP'. fgrep treats all match chars as
5994 literals.
5995 (AC_PROG_EGREP): Pass 'EGREP$'.
5996 (AC_PROG_GREP): Pass 'GREP$'.
5998 2004-04-20 Albert Chin-A-Young <china@thewrittenword.com>
6000 * lib/autoconf/programs.m4 (AC_PROG_GREP): Cache variable
6001 is `ac_cv_path_GREP', not `oc_cv_path_GREP'.
6003 2004-03-29 Paul Eggert <eggert@twinsun.com>
6005 * doc/autoconf.texi (Particular Headers, Particular Types, Generic
6006 Types, Specific Compiler Characteristics, System Services,
6007 Obsolete Macros): Use 'long int', 'short int', 'unsigned int'
6008 etc. consistently instead of 'long', 'short', 'unsigned' etc.
6009 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE(C), AC_C_BIGENDIAN): Likewise.
6010 * lib/autoconf/functions.m4 (AC_FUNC_MMAP, AC_FUNC_SELECT_ARGTYPES):
6011 Likewise.
6012 * lib/autoconf/headers.m4 (AC_HEADER_SYS_WAIT): Likewise.
6013 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS, AC_TYPE_SIZE_T,
6014 AC_TYPE_OFF_T): Likewise.
6015 * tests/semantics.at (AC_CHECK_TYPES: backward compatibility):
6016 Likewise.
6018 * tests/foreign.at (Libtool): Create an empty aclocal.m4, to
6019 pacify libtool 1.5.2. Fix quoting problems in sed command.
6021 2004-03-28 Paul Eggert <eggert@twinsun.com>
6023 * doc/autoconf.texi (Particular Structures): AC_STRUCT_TIMEZONE
6024 now defines HAVE_DECL_TZNAME if it is declared, when
6025 HAVE_STRUCT_TM_TM_ZONE is not defined.
6026 * lib/autoconf/types.m4 (AC_STRUCT_TIMEZONE): Implement this.
6027 Do not assume atoi. Rely on HAVE_DECL_TZNAME when testing
6028 for HAVE_TZNAME.
6030 2004-03-28 Steven G. Johnson <stevenj@fftw.org>
6032 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Corrected
6033 superfluous backslashing of quotes (") in sed expressions;
6034 thanks to Paul Eggert.
6036 2004-03-26 Steven G. Johnson <stevenj@alum.mit.edu>
6038 * lib/autoconf/fortran.m4 (_AC_PROG_FC): new name of Intel
6039 Fortran compiler is ifort, also added pghpf; thanks to Nelson
6040 H. F. Beebe for the bug report.
6042 2004-03-26 Steven G. Johnson <stevenj@fftw.org>
6044 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): fix for
6045 quoted -cmdline argument in Portland Group compiler (bug
6046 reported by Jeffrey J. Barteet).
6048 2004-03-25 Kevin Ryde <user42@zip.com.au>
6050 * doc/autoconf.texi (Specifying Names): Move cross_compiling ovindex to
6051 (Run Time): ... here, where it's now mentioned.

6072 AC_CHECK_TOOLS.
6073 (Specifying Names): Document the reason for these future
6074 behavioral changes.
6075 * tests/mktests.sh: Do not generate tests for the
6076 new macros.
6077 * NEWS: Document these changes.
6079 * doc/autoconf.texi: Avoid macros with unbraced arguments,
6080 they make TeX hang up.

6085 * doc/autoconf.texi (Generic Compiler Characteristics): Document it.
6086 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Use long int rather than
6087 int; avoid "a `$1'" since this isn't grammatical if $1 begins with a
6088 vowel.
6089 (AC_CHECK_ALIGNOF): New macro.
6090 * tests/mktests.sh (ac_exclude_list): Exclude AC_CHECK_ALIGNOF.
6091 * tests/semantics.at (AC_CHECK_ALIGNOF): Add tests similar to

6094 2004-03-03 Paul Eggert <eggert@twinsun.com>
6096 * bin/Makefile.am (edit): Don't use $< in a context where
6097 POSIX doesn't require support for it. Use $@.in instead.
6098 Problem reported by Anthony N. Frasso in
6099 <http://mail.gnu.org/archive/html/autoconf/2004-03/msg00008.html>.
6100 * bin/autoscan.in, bin/autoupdate.in: Add @configure_input@ comment.
6102 2004-02-23 Gary V. Vaughan <gary@gnu.org>

6113 2004-02-18 Paul Eggert <eggert@twinsun.com>
6115 Fix a dependencies problem, stemming from a Autoconf 2.59 build
6116 problem on QNX reported by Stephen Rasku in
6117 <http://mail.gnu.org/archive/html/bug-autoconf/2004-02/msg00066.html>.
6119 * bin/Makefile.am ($(srcdir)/autoconf.in): Depend on
6120 $(m4sh_m4f_dependencies); this removes a FIXME.
6121 * tests/Makefile.am ($(srcdir)/wrapper.in): Likewise.
6122 (MAINTAINERCLEANFILES): Split into pieces,
6123 one per related section. Add $(srcdir)/wrapper.in.
6125 2004-02-09 Paul Eggert <eggert@twinsun.com>
6127 * doc/autoconf.texi (Setting Output Variables): Emphasize that
6128 AC_SUBST provides no portable way to escape literal newlines.
6130 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6131 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6132 Darwin uses -lcrt2.o and there's little point to cataloging all
6133 the system variants. Partial fix reported by Andreas Waechter in:
6134 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00006.html
6135 for bug reported by Nelson H. F. Beebe in:

6150 the behavior of the third argument.
6151 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Describe more
6152 correctly the behavior of the third argument. Document
6153 what the three macros that AU_DEFUN defines do. Fix
6154 warning message when the third argument includes $0

6158 Eric Sunshine <sunshine@sunshineco.com>
6159 Paul Eggert <eggert@twinsun.com>
6161 * lib/m4sugar/m4sh.m4 (M4SH-SANITIZE): New diversion.
6162 (AS_INIT): Output shell initialization there. Removed optional
6163 parameter. Expand _AS_SHELL_FN_SPY.
6164 (AS_INIT_WITH_SHELL_FN): Removed.
6165 (_AS_SHELL_FN_SPY): New macro.
6166 (AS_DETECT_REQUIRED, AS_DETECT_SUGGESTED): New
6167 macros.
6168 (AS_SHELL_SANITIZE): Remove loop to find better shell
6169 and documentation for the parameter.
6170 (_AS_DETECT_BETTER_SHELL): Move it here.
6171 (_AS_SHELL_FN_WORK): Remove shell invocation, reformat.
6172 (_AS_RUN): Move it here, support testing with eval.
6173 (AS_REQUIRE_SHELL_FN): Require shell functions when
6174 it is used.
6175 (_AS_LINENO_WORKS): Put around braces, we do not
6176 trigger the bash bug anymore.

6178 use AS_INIT_WITH_SHELL_FN.
6179 * bin/autoconf.in, tests/wrapper.in: Regenerated.
6181 2004-01-30 Paolo Bonzini <bonzini@gnu.org>

6198 * lib/autoconf/status.m4: Remove FIXME.
6199 * tests/local.at (AT_CHECK_AU_MACRO): Ignore stderr, check
6200 that the macro is not present anymore in the updated
6201 configure.ac.
6202 * tests/tools.at (autoupdate AC_LINK_FILES): Ignore stderr
6203 of autoupdate.

6208 copyright years.
6209 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6210 2003 (except 1997) to the list of copyright years. This undoes
6211 the 2003-05-22 change, which removed the older years from the list.
6212 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.
6214 2004-01-27 Gary V. Vaughan <gary@gnu.org>

6220 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Factor out the core of
6221 AC_PROG_GREP.
6222 (AC_PROG_EGREP, AC_PROG_FGREP): Use it to find best available
6223 egrep and fgrep respectively if $GREP -E/-F don't work.
6224 (_AC_PATH_PROG_FEATURE_CHECK): Factor out the common core of
6225 _AC_PROG_GREP, and AC_PROG_SED.
6226 (_AC_FEATURE_CHECK_LENGTH): New helper macro for finding the
6227 longest input length accepted by a command.
6228 (AC_PROG_SED): Use it.
6229 * doc/autoconf.texi (Particular Programs): Document the changes.
6230 * NEWS: Updated.
6232 2004-01-27 Paul Eggert <eggert@twinsun.com>

6254 sources.
6256 2004-01-26 Paul Eggert <eggert@twinsun.com>
6258 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6259 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6260 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6261 not <inttypes.h>. Problem reported by Tim Mooney in
6262 <http://mail.gnu.org/archive/html/bug-coreutils/2004-01/msg00147.html>.
6263 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6264 Likewise.
6266 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6267 otherwise "make check" fails because it forbids cmp (I guess
6268 because cmp treats files as binary on DOS-like systems).
6270 * tests/mktests.sh: Update copyright date to 2004, since some tests
6271 have changed in 2004.
6273 2004-01-23 Gary V. Vaughan <gary@gnu.org>
6275 * lib/autoconf/programs.m4 (AC_PROG_SED): New macro to test for a
6276 non-truncating sed or gsed program in PATH.
6277 * tests/acprograms.at: Add it.
6278 * doc/autoconf.texi (Particular Programs): Document it.
6279 * NEWS: Updated.
6281 2004-01-15 Paul Eggert <eggert@twinsun.com>
6283 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6284 -std1 disables some useful extensions on Tru64. Problem reported
6285 by N. Lichtmaier in
6286 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00100.html>.
6288 2004-01-14 Paul Eggert <eggert@twinsun.com>
6290 * doc/autoconf.texi (Programming in M4sh): Document that
6291 AS_MKDIR_P succeeds if the destination is a symbolic link
6292 to an existing directory.
6293 (Limitations of Usual Tools): Note that mkdir -p might not
6294 succeed on symlinks to directories.
6296 2004-01-13 Paul Hilfinger <hilfinger@CS.Berkeley.EDU>
6298 * lib/autoconf/autoupdate.m4 (AU_DEFUN): Grammar fix in comment.
6299 * bin/autoheader.in: Grammar fix in message.
6300 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P):

6312 2004-01-09 Paul Eggert <eggert@twinsun.com>
6314 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6315 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6316 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6317 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6318 AC_COMPILE_IFELSE, since we now assume our caller invokes
6319 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6320 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6321 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6322 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6324 2004-01-07 Paul Eggert <eggert@twinsun.com>
6326 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6327 `"'...'"`, as it's confusing (and I suspect it may not work on
6328 some platforms). The code was incorrect anyway, as it assumed
6329 that \$ evaluated to itself in that context. Reported by
6330 Alexandre Duret-Lutz.
6332 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>

6384 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6385 -c -o might not work. From a suggestion by Kevin Ryde.
6386 (C Compiler, Generating Sources, Limitations
6387 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6388 Don't put '-o' after non-options, as POSIX doesn't allow this.

6442 functions work.
6443 (_AS_LINENO_WORKS): Don't find another shell if $LINENO
6444 does not work.
6445 (AS_INIT): Pass parameter down to AS_SHELL_SANITIZE.

6460 them on the fly.
6462 2003-11-24 Akim Demaille <akim@epita.fr>
6464 * doc/autoconf.texi (Particular Programs): AC_PROG_LEX can

6794 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set DUALCASE=1, for MKS sh.
6795 Problem reported by Lars J. Aas in
6796 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6797 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6798 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:
6799 http://mail.gnu.org/archive/html/autoconf-patches/2003-09/msg00039.html
6801 2003-09-26 Akim Demaille <akim@epita.fr>
6803 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6804 directory for AC_CONFIG_COMMANDS' first argument exists.
6805 This makes valid the invocation of _AC_SRCPATH that follows.
6806 Reported by Eric Sunshine.
6807 * doc/autoconf.texi (Configuration Commands): Adjust.
6809 2003-09-26 Akim Demaille <akim@epita.fr>
6811 * bin/autoscan.in (Autom4te::FileUtils): Use it for find_file.
6812 Reported by Ralf Corsepius.
6814 2003-09-26 Akim Demaille <akim@epita.fr>
6816 * lib/autoconf/general.m4 (AC_HELP_STRING): Don't overquote the
6817 arguments.
6818 Actually, use AU_ALIAS.
6819 From Bruno Haible.
6821 2003-09-26 Paul Eggert <eggert@twinsun.com>
6823 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): If mkdir -p . fails,
6824 rm -fr ./-p to remove junk left behind on NextStep and OpenStep.
6825 Problem reported by Eric Sunshine in:

6830 The test suite are sometimes assigning timings incorrectly.
6831 Reported by Henk Krus.
6832 Diagnosed by Nicolas Joly.
6834 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6835 AT_help_all.
6836 Instead of making AT_help a sequence of assignments to grow
6837 $at_help_all, just make AT_help_all be the growing contents of
6838 $at_help_all, and make a single assignment in...
6839 (AT_INIT): here.
6840 (at_times_skip): Flip the meaning and rename as...
6841 (at_times_p): this.
6842 (AT_INIT): When summarizing the test that ran, remove
6843 $at_times_file after use, and check it is present before trying to
6844 use it.
6846 2003-09-25 Akim Demaille <akim@epita.fr>
6848 Version 2.57d.
6850 * bin/Makefile.am (edit): Handle '@configure_input@'.
6851 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6852 (ifnames): chmod -w.
6853 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6854 executables, not bin/ executables! Otherwise all the magic needed
6855 to find non installed files is turned off. This caused a failure
6856 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6857 as found in its environment (sent by tests/autoreconf): pointing
6858 to bin/autom4te that could not find its files.
6859 * tests/mktests.sh: Force the replacement of generated files, for
6860 the sake of "mv" program that are interactive when overwriting a
6861 -w file.
6862 * config/install-sh: Upgrade from CVS Automake.
6864 2003-09-23 Paul Eggert <eggert@twinsun.com>
6866 * doc/autoconf.texi (Limitations of Builtins): Document test -h
6867 versus test -L issues.
6869 2003-09-23 Daniel Jacobowitz <drow@mvista.com> and
6870 Paul Eggert <eggert@twinsun.com>
6872 Trivial change to support GCC's configuration procedure.
6873 * lib/autoconf/c.m4 (AC_PROG_CPP_WERROR): New macro.
6874 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Don't warn
6875 about inconsistency if the preprocessor is set to give errors for
6876 any warning.
6877 * doc/autoconf.texi (C Compiler Characteristics): Document this.
6879 2003-09-13 Alexandre Duret-Lutz <adl@gnu.org>
6881 * Makefile.am (autom4te-update, autom4te_files): Fetch Struct.pm
6882 and XFile.pm from Automake.

6885 2003-09-12 Akim Demaille <akim@epita.fr>
6887 Version 2.57c.
6889 2003-09-12 Akim Demaille <akim@epita.fr>
6891 * config/config.guess, config/config.sub, config/missing,
6892 * lib/Autom4te/Channels.pm, lib/Autom4te/Configure_ac.pm: Update
6893 from masters.
6895 2003-09-12 Akim Demaille <akim@epita.fr>
6897 * doc/autoconf.texi (Header Portability): Promote linux/types.h,
6898 not asm/types.h.
6900 2003-09-11 Akim Demaille <akim@epita.fr>
6902 * doc/autoconf.texi (Header Portability): linux/random.h.
6903 From Peter Hendrickson.
6905 2003-09-10 Akim Demaille <akim@epita.fr>
6907 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6908 willing to edit the output files.
6910 2003-09-10 Akim Demaille <akim@epita.fr>
6912 * tests/fortran.at (GNU Fortran 77): Also exercise AC_FC_SRCEXT
6913 and AC_FC_FREEFORM.
6914 * tests/mktests.sh: Skip AC_FC_SRCEXT.
6915 * lib/autoconf/fortran.m4 (AC_FC_SRCEXT, AC_FC_FREEFORM): Likewise.
6917 2003-09-09 Akim Demaille <akim@epita.fr>
6919 * lib/Autom4te/FileUtils.pm (&update_file): s/cannot not/cannot/g.
6920 Reported by Gary Vaughan.
6921 * bin/autom4te.in (handle_m4): Likewise.
6923 2003-09-09 Akim Demaille <akim@epita.fr>
6925 * lib/Autom4te/FileUtils.pm (&update_file): Be sure not to leave
6926 trailing files.
6928 2003-09-07 Paul Eggert <eggert@twinsun.com>
6930 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS):
6931 Improve the accuracy of the wording about obsolescence.
6932 From a suggestion by Ian Lance Taylor in
6933 <http://mail.gnu.org/archive/html/autoconf/2003-09/msg00044.html>.
6935 2003-09-05 Paul Eggert <eggert@twinsun.com>
6937 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Try -ffree-form too,
6938 for the benefit of g77 3.2. Fix suggested by Steven G. Johnson.
6940 2003-09-04 Akim Demaille <akim@epita.fr>
6942 * tests/mktests.sh (ac_exclude_list): Fix the filtering of
6943 AC_FUNC_WAIT3.
6945 2003-09-04 Akim Demaille <akim@epita.fr>
6947 * bin/autom4te.in: Use &fatal where more appropriate than &error.
6948 (freeze): When exiting, use $exit_code.
6949 * lib/autoconf/fortran.m4: Comment changes.
6951 2003-09-04 Akim Demaille <akim@epita.fr>
6953 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6955 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6957 Add support for newer Fortran dialects. The F77 interface is
6958 unchanged, and continues to support Fortran 77. New FC macros
6959 correspond to all the old F77 macros, with output variables FC,
6960 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
6961 available dialect, but older dialects can be specified. There are
6962 new macros AC_FC_SRCEXT to set the source extension, and
6963 AC_FC_FREEFORM to accept free-form source files.
6965 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):
6966 New macros.
6967 (AC_LANG_PROGRAM(C)): Invoke _AC_LANG_PROGRAM_C_FC_HOOKS if defined.

6982 AC_F77_DUMMY_MAIN, AC_F77_MAIN, _AC_F77_NAME_MANGLING,
6983 AC_F77_NAME_MANGLING, AC_F77_WRAPPERS, AC_F77_FUNC):
6984 Rewrite in terms of the above.
6985 (_AC_PROG_F77_G, _AC_PROG_F77_V_OUTPUT, _AC_PROG_F77_V): Remove.
6986 * lib/autoconf/lang.m4 (_AC_LANG_PREFIX): New macro.
6987 * tests/acfortran.at: Test AC_FC_FREEFORM, AC_FC_FUNC,
6988 AC_FC_MAIN, AC_FC_SRCEXT, AC_FC_WRAPPERS, AC_PROG_FC_C_O.
6990 2003-09-02 Paul Eggert <eggert@twinsun.com>
6992 * doc/autoconf.texi (Limitations of Usual Tools, Limitations of Make):
6993 Document problems with timestamp resolution that 'make', 'cp -p', and
6994 'touch -r' have.
6996 2003-08-27 Akim Demaille <akim@epita.fr>
6998 * tests/m4sugar.at (cross_warning): Make sure to enable the
6999 output, so that we can track spurious m4sugar output.
7000 * tests/local.at: Require 2.57.
7001 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't m4_default the arguments that
7002 are defaulted by AT_CHECK anyway.
7003 Use AT_CHECK_AUTOM4TE.
7004 * lib/m4sugar/m4sugar.m4: There should be no output at all: add a
7005 missing dnl.
7007 2003-08-27 Akim Demaille <akim@epita.fr>
7009 * bin/autoheader.in: Issue the "Using auxiliary..." message only
7010 when -Wobsolete is set.
7011 Set it on by default.
7012 Suggested by Klee Dienes.
7014 2003-08-27 Akim Demaille <akim@epita.fr>

7081 2003-08-21 Akim Demaille <akim@epita.fr>
7083 * bin/autoheader.in (&parse_args): Use &parse_warnings and
7084 &parse_WARNINGS.
7085 ($help): Use Autom4te::ChannelDefs::usage.
7086 * bin/autoscan.in: Use Autom4te::ChannelDefs.
7087 * lib/Autom4te/General.pm: Don't export error: you don't own it.
7089 2003-08-21 Akim Demaille <akim@epita.fr>
7091 First stab at preserving warnings between calls to autom4te,
7092 including when the cache is used.
7094 There are still several issues: (i) there are too many runs of m4
7095 (one for include, one for warnings, and some more), (ii) warnings
7096 spreading on several lines are not handled gracefully, (iii) the
7097 code meant to have the call stack display for errors does not work
7098 (its handling should move from m4 to autom4te).
7100 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7101 Use them.
7102 (@preselect): Add m4_warn.
7103 ($exit_status): Remove, use $exit_code.
7104 ($help): Use Autom4te::ChannelDefs::usage.
7105 (&handle_m4): No longer define the m4_warnings.
7106 At each run, extract and report the warnings.
7107 Always cache the result, including if the exit status is on
7108 failure, since if nothing changes, we should result in the same
7109 failure, hence we can use the cache.
7110 * lib/m4sugar/m4sugar.m4 (m4_warning_ifelse, _m4_warning_ifelse)
7111 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7112 Remove.
7113 (m4_warn): Redefine as a do-nothing: it is its invocation that
7114 matters, as warnings are now reported via traces.
7115 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7116 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7117 the latter reveals calls to the former.
7119 Adjust the tests.
7121 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.
7123 2003-08-21 Akim Demaille <akim@epita.fr>
7125 * bin/autoreconf.pm (Autom4te::Channels, Autom4te::ChannelDefs):

7130 * lib/Autom4te/FileUtils.pm (&find_file): Walk the @include in
7131 forward order.
7132 * lib/Autom4te/ChannelDefs.pm: Doc typos.
7133 (&parse_warnings): Accept a list of warning requests.
7134 (&usage): Return a string, not a side effect.
7135 (cross): New warning category.
7137 2003-08-21 Akim Demaille <akim@epita.fr>
7139 * lib/Autom4te/Configure_ac.pm (&find_configure_ac)
7140 (&require_configure_ac): Accept an optional directory argument.
7141 ($configure_ac): Remove.
7142 * lib/Autom4te/General.pm (&find_configure_ac, &canonfile)
7143 (&catfile): Remove.
7144 * bin/autoheader.in, bin/autoreconf.in, bin/autoupdate.in,
7145 * bin/autoscan.in: Adjust.
7147 2003-08-20 Akim Demaille <akim@epita.fr>
7149 * bin/autoheader.in: Remove duplicate 'use Autom4te::FileUtils'.
7150 Reported by Alexandre Duret-Lutz.
7152 2003-08-20 Akim Demaille <akim@epita.fr>
7154 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7155 * bin/autom4te: Adjust.
7156 In particular, be Autoconf tools are really silent when properly
7157 working, bind the verbosity of the 'note' channel to $verbose.
7158 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)
7159 (&xsystem, &contents): Remove, since they are exported by...
7160 * lib/Autom4te/FileUtils.pm: this.
7161 More perldoc.
7162 * lib/Autom4te/General.pm (&up_to_date_p): Move to...
7163 * lib/Autom4te/FileUtils.pm: here.
7165 2003-08-20 Akim Demaille <akim@epita.fr>
7167 * lib/Autom4te/Channels.pm, lib/Autom4te/ChannelDefs.pm
7168 * lib/Autom4te/Configure_ac.pm, lib/Autom4te/FileUtils.pm: New,

7220 * lib/autotestgeneral.m4 (AT_INIT): Reformat test summary line to print
7221 DESCRIPTION rather than FILE and LINE. Shorten result to fit in new,
7222 shorter column three. Add DESCRIPTION to log file content.
7224 2003-08-13 Derek Price <derek@ximbiot.com>
7226 * lib/autotest/general.m4 (AT_INIT): Correct typo in final status
7227 output.

7263 (This really should be 'intptr_t', not 'long', but that would
7264 take more work.)
7266 2003-06-25 Akim Demaille <akim@epita.fr>
7268 * lib/Makefile.am (autom4te.cfg): Make it read only.
7269 Depend on Makefile since it contains substitutions.
7270 From Paolo Bonzini.
7271 * lib/autom4te.in (args): Add local.at? for Autotest args.
7272 This change was made on autom4te.cfg which is generated.
7273 Reported by Raja R. Harinath.
7275 2003-06-25 Akim Demaille <akim@epita.fr>
7277 * doc/autoconf.texi (Header Portability): sys/mount.h.
7278 From Gareth McCaughan.
7280 2003-06-23 Akim Demaille <akim@epita.fr>
7282 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7283 not all of them. This fixes 1. the fact that when testing
7284 Autoconf there are many many config.log, 2. the incorrect use of
7285 top_srcdir to find config.log.
7286 Don't mix the detailed output of failed test with the summary of
7287 failures. Rather, append detailed log afterwards.
7289 2003-06-23 Akim Demaille <akim@epita.fr>
7291 * tests/local.at (AT_CHECK_CONFIGURE): Adjust to the verbose being
7292 always run: output config.log on $at_group_log.
7294 2003-06-23 Akim Demaille <akim@epita.fr>
7296 * tests/torture.at (#define header templates): Don't use quotes in
7297 C++ comments as it puzzles Emacs' sh font-lock-mode.
7299 2003-06-23 Akim Demaille <akim@epita.fr>
7301 * tests/mktests.sh (au_exclude_egrep): Fix output copyright notice.
7302 * lib/autom4te.cfg (args): Add local.at? for Autotest args.
7303 * tests/atspecific.m4: Rename as...
7304 * tests/local.at: This.
7305 * tests/suite.at: Move the globals into...
7306 * tests/local.at: here.
7307 * tests/Makefile.am: Adjust.
7308 * doc/autoconf.texi (testsuite Scripts): Adjust.
7310 2003-06-21 Kevin Ryde <user42@zip.com.au>
7312 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Extend test program to get an
7313 error from OSF 4.0 Compaq cc in its default almost-ANSI mode, thereby
7314 ensuring we add -std1 for full-ANSI.
7316 * doc/autoconf.texi (hdrindex): New macro.
7317 Add index entries for portability of various standard header files.
7319 2003-06-20 Akim Demaille <akim@epita.fr>
7321 * configure.ac: Bump to 2.57b.
7323 2003-06-20 Akim Demaille <akim@epita.fr>
7325 Version 2.57a.
7327 2003-06-20 Akim Demaille <akim@epita.fr>
7329 * bin/autom4te.in: Don't rely on $HOME being defined.
7330 Reported by Marc Espie as PR/233.
7332 2003-06-20 Akim Demaille <akim@epita.fr>
7334 * lib/autotest/general.m4: Use at_times_file only if used.
7335 From Nicolas Joly.
7337 2003-06-20 Akim Demaille <akim@epita.fr>
7339 * config/config.guess, config/config.sub, config/elisp-comp,
7340 * config/install-sh, config/mkinstalldirs, doc/standards.texi:
7341 Update from masters.
7343 2003-06-11 Paolo Bonzini <bonzini@gnu.org>
7345 * doc/autoconf.texi (Writing testsuite.at): Document AT_XFAIL_IF
7346 * lib/autotest/general.m4 (AT_XFAIL_IF): New macro.
7347 (TEST_SCRIPT): New diversion.
7348 (AT_SETUP): Divert output to TEST_SCRIPT and move some code...
7349 (AT_CLEANUP): ...to here. Undivert TEST_SCRIPT.
7350 (AT_INIT): Support for expected failures.
7352 2003-06-02 Akim Demaille <akim@epita.fr>
7354 * bin/autom4te.in, bin/autoscan.in, bin/autoheader.in: White space
7355 changes.
7356 * lib/Autom4te/General.pm (&backname): Remove, no longer used by
7357 Autoconf nor Automake.
7358 (&contents): New, from Automake.
7359 PODify.
7361 2003-05-28 Paul Eggert <eggert@twinsun.com>
7363 * NEWS, doc/autoconf.texi (Particular Functions),
7364 lib/autoconf/functions.m4 (AC_FUNC_MKTIME): Check that mktime
7365 is the inverse of localtime.
7367 2003-05-25 Alexandre Duret-Lutz <adl@gnu.org>
7369 * lib/Autom4te/General.pm (END): Print diagnostics to STDERR.
7370 (handle_exec_errors): New function. Work around $! being
7371 altered by WEXITSTATUS.
7372 (xqx, xsystem): Use handle_exec_errors.
7374 2003-05-23 Alexandre Duret-Lutz <adl@gnu.org>
7376 * lib/Autom4te/General.pm (END): Rewrite exit code processing.
7377 Do not call `_exit()', simply modify `$?'.
7378 (xsystem): Reset $! before running system, and check it afterward.
7379 * tests/tools.at (autoupdating AC_PREREQ): Expect exit status
7380 63 for version mismatches.
7382 2003-05-23 Akim Demaille <akim@epita.fr>
7384 * lib/autoconf/status.m4: Prefer "TAB-SP" to "SP-TAB", because of
7385 Emacs' dangerous whitespace.el behavior (smashing "useless" spaces in
7386 the middle of a line).
7387 * lib/m4sugar/m4sugar.m4: Likewise.
7388 Remove useless spaces in comments.
7390 2003-05-23 Akim Demaille <akim@epita.fr>
7392 * lib/m4sugar/m4sugar.m4 (m4_version_prereq): Failure causes an
7393 exit 63, so that we (or Automake's "missing") can tell the
7394 difference with a plain failure.
7395 * doc/autoconf.texi (Notices): Adjust.
7397 2003-05-23 Akim Demaille <akim@epita.fr>
7399 * Makefile.am, bin/Makefile.am, config/Makefile.am,
7400 * doc/Makefile.am, lib/autoconf/Makefile.am, tests/Makefile.am:
7401 White spaces cleanup.
7403 2003-05-22 Jim Meyering <jim@meyering.net>
7404 Paul Eggert <eggert@twinsun.com>
7406 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7407 Remove `#include <stdlib.h>' from the list; we should never
7408 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7409 resulting namespace pollution would cause other tests to fail.
7410 Configure scripts run with some older versions of g++ and HP's
7411 aCC would fail due to such an #include. Problems reported by
7412 Matthew Mueller in <http://bugs.debian.org/120704> and by
7413 Keith Bostic in
7414 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7415 In the test, use the test declaration before including <stdlib.h>,
7416 as that's closer to how it'll be used.
7418 2003-05-23 Akim Demaille <akim@epita.fr>
7420 * doc/autoconf.texi (Header Portability): ucred.h.
7421 From Ian Redfern.
7423 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7425 Overhaul Autotest's logging: generate separate log files
7426 in testsuite.dir/NNN/testsuite.log, and append them to
7427 testsuite.log instead of re-running the test verbosely.
7429 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7430 file descriptor, write 0 to at_status_file instead of setting
7431 at_status=0, initialize some new variables (at_status_file,
7432 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7433 to rerun the tests, instead append the at_group_log to the
7434 at_suite_log when a test fails.
7435 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7436 with the AS_MESSAGE_LOG_FD redirected to stdout.
7437 (AT_CLEANUP): save the output status in $at_status_file
7438 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7439 its original place.
7440 (AT_CHECK): since tests are run with a redirected stdout,
7441 and used to be re-run in verbose mode, turn some $at_verbose
7442 into echo, and don't redirect the output of testing stdout
7443 and stderr.
7445 * lib/autotest/autoconf.texi (testsuite Scripts): Update
7446 the name of the debugging directory and information about
7447 its contents.
7449 2003-05-22 Paolo Bonzini <bonzini@gnu.org>
7451 * lib/m4sugar/m4sh.m4 (AS_REQUIRE): Actually use the 2nd
7452 parameter.
7454 2003-05-22 Akim Demaille <akim@epita.fr>
7456 * lib/autoconf/autotest.m4, lib/autoconf/autoupdate.m4

7475 Suggested by Jim Meyering.

7483 2003-05-22 Akim Demaille <akim@epita.fr>
7485 * doc/autoconf.texi: Replace AC_HELP_STRING AS_HELP_STRING.

7518 2003-05-17 Akim Demaille <akim@epita.fr>
7520 * lib/autoconf/functions.m4: Use the default includes so that
7521 memcmp be declared before being tested.
7522 Reported by Sander Niemeijer.
7523 (AC_FUNC_ERROR_AT_LINE, AC_FUNC_GETGROUPS, AC_FUNC_STRNLEN): Likewise.
7524 * doc/autoconf.texi (Default Includes): Document
7525 AC_INCLUDES_DEFAULT.
7527 2003-05-17 Akim Demaille <akim@epita.fr>
7529 * lib/autoconf/specific.m4: Include signal.h and unistd.h.
7530 * doc/autoconf.texi (Obsolete Macros): Adjust.

7564 and truncate.
7566 2003-05-06 Akim Demaille <akim@epita.fr>
7568 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7569 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7570 by aclocal.m4 is changed it might require the importing of another
7571 m4 extension file, i.e., aclocal must be run.
7573 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7574 (&parse_args): Use --force with aclocal if required and supported.
7575 (&autoreconf_current_directory): Use &run_aclocal.

7581 * lib/Autom4te/XFile.pm ($me, &name, &lock, &truncate, &seek): New.
7582 * bin/autom4te.in (&Request::save, &Request::load): Use an IO::File
7583 argument instead of a file name, so that the request file remains
7584 open during the whole autom4te run.
7585 ($icache_file): New.
7586 (&freeze): Lock the $icache_file.
7588 2003-04-29 Derek Price <derek@ximbiot.com>
7590 * lib/autotest/general.m4 (AT_KEYWORDS): Don't use a comma as the
7591 seperator with m4_append_uniq(). It doesn't work.
7592 (AT_CLEANUP): Add `;' to end of at_help_all.
7593 (AT_INIT): Allow --keywords to be specified more than once. When
7594 grepping $at_help_all for keywords, use the field and keyword
7595 seperators to ensure a complete keyword match. Alter at_prev handling
7596 to support the new --keywords behavior.
7598 2003-04-27 Karl Berry <karl@freefriends.org>
7600 * doc/autoconf.texi: Make the dir entries in the autoconf manual
7601 align better with others. I also made some of the individual
7602 entries on one line, for brevity and to make it easier for me to
7603 sort my dir-example file in the Texinfo distribution :).
7605 2003-04-12 Jim Meyering <jim@meyering.net>
7607 * NEWS: Mention the new macro.
7608 * lib/autoconf/c.m4 (AC_C_RESTRICT): New macro.

7643 New.
7644 Use them.
7645 * doc/Makefile.am (CLEANFILES): Adjust.
7646 (TEXI2DVI): Make it --batch.
7648 2003-03-31 Derek Price <derek@ximbiot.com>
7650 * lib/autotest/general.m4: Revert the checkin from 2003-03-27
7651 which removed the main loop.
7652 Thanks to Akim Demaille.
7654 2003-03-29 Akim Demaille <akim@epita.fr>
7656 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Skip OS/2's install,
7657 that starts a GUI.
7658 From Ilya Zakharevich.
7660 2003-03-29 Akim Demaille <akim@epita.fr>
7662 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): The
7663 documentation to read is Autoconf's.
7664 Suggested by Paul Eggert.
7666 2003-03-28 Akim Demaille <akim@epita.fr>
7668 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): Suggest
7669 reading the section "Present But Cannot Be Compiled" when the
7670 header causes problems.
7672 2003-03-28 Akim Demaille <akim@epita.fr>
7674 * tests/torture.at (Configuring subdirectories): Require aclocal
7675 1.4, otherwise the test fails, as it does support configure.ac.
7676 This fixes the "test 40 failed" bug reports.
7678 2003-03-28 Akim Demaille <akim@epita.fr>
7680 * doc/autoconf.texi (C Compiler): `#line' portability.
7681 From Paul Eggert and Nelson H. F. Beebe.
7683 2003-03-27 Derek Price <derek@ximbiot.com>
7685 * lib/autotest/general.m4: Eliminate main loop and reorganize test
7686 layout in order to allow scripting around test groups.
7688 2003-03-27 Derek Price <derek@ximbiot.com>
7690 * lib/autotest/general.m4 (PARSE_ARGS,PARSE_ARGS_END,HELP,HELP_MODES,
7691 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7692 use new diversions in preparation for accepting new arguments and

7709 sense. Verbosify the diversion definitions comment.
7711 2003-03-26 Derek Price <derek@ximbiot.com>
7713 * lib/autotest/general.m4 (AT_INIT): Remove redundant call to
7714 AS_PREPARE.
7716 2003-03-21 Eric Siegerman <eric_97@pobox.com>

7735 file name for the m4 program, when it has an "exe" file extension.

7737 remove the error code during normalization.
7739 2003-02-28 Akim Demaille <akim@epita.fr>
7741 * doc/autoconf.texi (Present But Cannot Be Compiled): New.
7743 2003-02-28 Alexandre Duret-Lutz <adl@gnu.org>
7745 * doc/autoconf.texi (Limitations of Make): Remove the section
7746 about `$<' in inference rules, it was a bogus interpretation of
7747 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
7748 Tru64 make in the "target lookup" section.
7749 (Automake): Automake 1.5+ no longer requires special tools to be
7750 present on the developer's host.
7752 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
7754 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
7755 to a shell that can handle redirection or quoting correctly.
7756 Override SHELL with the shell detected by configure.
7757 Use of $^O suggested by Tim van Holder.
7758 * bin/autom4te.in (BEGIN): Likewise.
7759 * bin/autoreconf.in (BEGIN): Likewise.
7760 * bin/autoscan.in (BEGIN): Likewise.
7761 * bin/autoupdate.in (BEGIN): Likewise.
7762 * bin/ifnames.in (BEGIN): Likewise.
7764 * bin/ifnames.in: Add final newline to help and version messages.
7766 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Translate colons,
7767 to cope with DOS-style absolute paths, when constructing
7768 ${ac_make}.
7770 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS, _AC_OUTPUT_FILES):
7771 When constructing paths with IFS=:, quote the path. If we're
7772 constructing a DOS-style absolute path, we don't want to split it
7773 on the colon.
7775 * tests/atspecific.m4 (AT_CHECK_CONFIGURE): Fix typo
7776 in description.
7778 2003-02-25 Pavel Roskin <proski@gnu.org>

7786 2002-09-01 patch by replacing "test -n" with "test -z".
7787 This fixes a bug found by Jeff Painter and reported by Tom Epperly in
7788 <http://mail.gnu.org/archive/html/autoconf/2003-02/msg00139.html>.
7790 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7791 to fix a mismatch between example and discussion.
7793 2003-02-24 Kevin Ryde <user42@zip.com.au>
7795 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7796 format starting with "-".
7798 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>
7800 * doc/autoconf.texi (Limitations of Make): `foo=bar make -e'
7801 is not portable inside Makefile.
7803 2003-02-20 Akim Demaille <akim@epita.fr>
7805 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7806 compiler says yeah, but preproc says nope, compiler is right.
7807 Conversely, prompt the reader to send a bug report to the
7808 maintainers of the package, not of Autoconf.
7810 2003-02-20 Klee Dienes <kdienes@apple.com>
7812 * bin/autoreconf.in (autoreconf_current_directory): Properly
7813 handle an empty aclocal.m4.

7817 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Quote
7818 $ac_prefix_program.
7819 From Larry Jones.
7821 2002-12-23 Paul Eggert <eggert@twinsun.com>
7823 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7824 innocuous variant befor including <limits.h> or <assert.h>. This
7825 works around a bug reported by Albert Chin: HP-UX 11i
7826 (and earlier versions) have a <limits.h> that declares
7827 gettimeofday and many other functions.
7829 2002-12-03 Paul Eggert <eggert@twinsun.com>
7831 Version 2.57.
7833 * NEWS, configure.ac: Update version.
7835 * doc/fdl.texi: Upgrade to FDL version 1.2.
7837 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7838 nontrivially in main's body, so that f's external declaration is
7839 not optimized away in AIX. This should fix the bug reported by
7840 Martin Frydl in
7841 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7843 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7844 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7845 defined, to support freestanding compilers. This should fix the
7846 bug reported by Momchil Velkov in
7847 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7849 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7850 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for

7855 * Makefile.maint (www-gnu): New macro.
7856 (standards.texi-url_prefix, make-stds.texi-url_prefix): Use it, as
7857 the location has moved.
7859 2002-12-02 Martin Frydl <martin@systinet.com>
7861 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7862 \(.*\) match is too long and there is something more to be checked.
7863 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>
7865 2002-11-15 Akim Demaille <akim@epita.fr>

7872 * Makefile.am (AUTOMAKE_OPTIONS): Move to...
7873 * configure.ac (AM_INIT_AUTOMAKE): here.
7874 Require 1.7.1.
7876 2002-11-14 Akim Demaille <akim@epita.fr>
7878 Version 2.55.
7880 * config/config.guess, config/config.sub, config/install-sh:
7881 Update from masters.
7883 2002-11-14 Akim Demaille <akim@epita.fr>
7885 * Makefile.maint: Sync with Bison, i.e.:
7886 (po-check): Scan .l and .y files instead of the
7887 .c and the .h files that they generate. This fixes the bug
7888 reported by Tim Van Holder in:
7889 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7890 Look for N_ as well as for _. Try to avoid matching #define for
7891 N_ and _.
7892 From Paul Eggert.
7894 2002-11-14 Akim Demaille <akim@epita.fr>
7896 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7897 From Paul Eggert and Albert Chin-A-Young.
7899 2002-11-14 Akim Demaille <akim@epita.fr>
7901 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7902 From Paul Eggert and Albert Chin-A-Young.
7904 2002-11-14 Kevin Ryde <user42@zip.com.au>
7906 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7907 than assigning in main, to avoid HP cc +O3 optimizing it away.
7909 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7911 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7912 option. Process --recheck after parsing all options. Pass -q
7913 option to configure on --recheck.
7914 (AC_OUTPUT): Pass -q from configure to config.status.
7915 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7916 arguments to record.
7917 * doc/autoconf.texi (config.status Invocation): Document
7918 config.status -q option.
7920 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7922 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore
7923 Makefile.in if Makefile.am exists.
7924 (output): Strip `.am' from Makefiles. Don't
7925 output AC_CONFIG_FILES if no Makefiles were found.
7927 2002-11-07 Akim Demaille <akim@epita.fr>
7929 * Makefile.am (cvs_files): Add elisp-comp, mdate-sh.

7934 2002-11-06 Akim Demaille <akim@epita.fr>
7936 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7937 declaration in extern "C" too.

7942 * tests/torture.at (Configuring subdirectories): Don't use grep
7943 -w.
7944 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7945 Reported by Ezra Peisach.
7947 2002-11-05 Akim Demaille <akim@epita.fr>
7949 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7950 Remove.
7951 We _have_ to stop using the old compatibility scheme that tried to
7952 avoid useless backslashes because Libtool 1.4.3 contains a
7953 AC_DEFINE([error_t], [int],
7954 [Define to a type to use for \`error_t' if it is not
7955 otherwise available.])
7956 We _have_ to quote the single quote and backslashes with \. The
7957 old compatibility scheme saw that ` was backslashed, and therefore
7958 did not quote the single quote. Hence before this patch, Autoconf
7959 was not compatible with Libtool.
7961 2002-11-04 Paul Eggert <eggert@twinsun.com>
7963 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,
7964 too: LC_ADDRESS, LC_IDENTIFICATION, LC_MEASUREMENT, LC_MONETARY,
7965 LC_NAME, LC_PAPER, LC_TELEPHONE.

7968 2002-11-04 Akim Demaille <akim@epita.fr>
7970 Version 2.54c.
7972 * Makefile.maint (update, cvs-update, po-update, do-po-update):
7973 New.
7974 * config/texinfo.tex: Update.
7976 2002-11-03 Akim Demaille <akim@epita.fr>
7978 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
7979 from...
7980 (&autoreconf): here.
7981 ($help, $make, &parse_args, &autoreconf_current_directory):
7982 Support -m/--make.
7983 * doc/autoconf.texi (autoreconf Invocation): Adjust.

8001 2002-10-31 Akim Demaille <akim@epita.fr>
8003 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use and display
8004 `$(MAKE)' instead of '${MAKE}' to emphasize that we refer to the
8005 Make variable, not a shell variable.
8006 Suggested by Bruno Haible.
8008 2002-10-31 Akim Demaille <akim@epita.fr>
8010 * bin/autom4te.in (load_configuration): Reject #args out of any
8011 language.
8013 2002-10-31 Akim Demaille <akim@epita.fr>
8015 * lib/autoconf/general.m4 (_AC_MSG_LOG_CONFTEST): New.

8027 Suggested by Tim van Holder.

8031 * doc/autoconf.texi (Particular Functions): AC_FUNC_MALLOC and
8032 AC_FUNC_REALLOC check for compatibility with glibc, not POSIX.
8033 Problem reported by Bruno Haible.
8035 2002-10-29 Akim Demaille <akim@epita.fr>
8037 * doc/autoconf.texi (Header Templates): Put also in words what the
8038 pictures says to assist free style readers.
8039 (Customizing autom4te): s/--cache=/--cache /.
8041 2002-10-29 Akim Demaille <akim@epita.fr>
8043 * lib/autoconf/functions.m4 (_AC_FUNC_VFORK): Include stdlib.h and
8044 sys/wait.h.

8269 `$ac_configure_args'.

8288 * doc/autoconf.texi (Limitations of Usual Tools): Remove incorrect
8289 words about HP-UX cmp: it was actually a user-written cmp.
8291 2002-10-22 Akim Demaille <akim@epita.fr>
8293 * tests/foreign.at (Libtool): Don't check autoconf's stderr: there
8294 are a few warnings.
8295 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):
8296 Quote for Perl '' strings, not "".
8297 * bin/autoheader.in: Invoke autoconf to get '' strings, not ""
8298 strings.
8300 2002-10-22 Akim Demaille <akim@epita.fr>
8302 * lib/m4sugar/m4sh.m4 (_AS_QUOTE): The warning about quoted
8303 characters is a syntax warning now.
8304 (_AS_QUOTE): Accept $2 as list of characters to quote.
8305 * lib/autoconf/autoheader.m4 (AH_VERBATIM, _AH_VERBATIM_OLD):

8310 `@', to tickle Perl's lists.
8311 Reported by Carlos Velasco.
8313 2002-10-18 Akim Demaille <akim@epita.fr>
8315 * bin/autom4te.in (handle_m4): Pass --fatal-warning to m4, so that

8325 2002-10-17 Akim Demaille <akim@epita.fr>
8327 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Don't use cmp.

8348 Because of caching, some files that no longer exist and are no
8349 longer required can still cause errors.
8350 Reported by Alexandre Duret-Lutz.
8352 * bin/autom4te.in (&parse_args): Do not prepend `--reload-state'
8353 to frozen files in @ARGV, as @ARGV must remain being a list of
8354 files. Rather, at M4 call sites, use this...
8355 (&files_to_options): New function.
8356 (&freeze): Use &error.
8357 (&up_to_date): If a file that was included according to the cache
8358 is no longer there, then the output is out dated.
8359 (&main): Don't even check whether a file is up to date is anyway
8360 --force is given.
8361 * tests/tools.at (autom4te cache): New.
8363 2002-10-16 Akim Demaille <akim@epita.fr>
8365 * bin/autoconf.as: Kill dead options.
8366 * bin/autoupdate.in (&parse_args): Kill old options.
8367 * bin/autoreconf.in (&parse_args): Remove dead options.
8368 Factor some code.
8369 (&autoreconf): Report the directories we enter *and leave*, so
8370 that error messages can be easily located, and use GNU Make
8371 format, so that Emacs' compile mode understands us.
8372 * lib/Autom4te/General.pm (&update_file): Use `verbose' to report
8373 if some file was changed instead of `print'.
8374 * bin/autoheader.in: Suggest AC_DEFINE with 3 args when needed.
8375 (&parse_args): Remove the dead options.
8376 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Adjust to the new

8385 check for compilability.
8387 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL)
8388 (AC_CHECK_HEADER, _AC_CHECK_HEADER_OLD): Remove.

8392 * lib/autotest/general.m4 (AT_INIT): Include the failed test
8393 numbers in the Subject suggestion.

8407 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE): Use $$ in the
8408 file name to enable parallel executions.
8409 From Sam Varshavchik.
8411 2002-10-08 Akim Demaille <akim@epita.fr>
8413 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8414 aclocal invocation, as Gettext macros might not be visible to
8415 aclocal.
8416 Instead of blindly running autopoint, scan configure.ac (not the
8417 traces) for AM_GNU_GETTEXT_VERSION uses, as autopoint does.
8418 Reported by Paul D. Smith.
8420 2002-10-08 Paul Eggert <eggert@twinsun.com>
8422 Work around problems found when POSIXLY_CORRECT=1 is set.
8423 None of this seems to have anything to do with POSIX, really,
8424 but it's how Perl getopt works.
8425 * bin/autom4te.in (parse_args): Configure GetOpt with
8426 "permute", too.
8427 * doc/autoconf.texi (Invoking autom4te):
8428 --warning -> --warnings.
8429 * lib/autom4te.in: --warning -> --warnings.

8448 2002-09-28 Akim Demaille <akim@epita.fr>
8450 * tests/torture.at (Configuring subdirectories): Be robust to
8451 users who use config.site to require for a cache: in this case,
8452 the two last configure runs, using two different sets of
8453 arguments, trigger a legitimate error.
8455 2002-09-28 Akim Demaille <akim@epita.fr>
8457 * tests/m4sh.at (Functions Support, Functions and return Support):
8458 New.

8471 (tm_zone): Move their rules to...
8472 * lib/autoconf/types.m4: here, using AN_ macros.
8473 * lib/autoscan/autoscan.pre (AWK, BISON, INSTALL, LEX, LN, MAKE)
8474 (RANLIB, YACC, awk, bison, byacc, flex, gawk, install, lex, ln)
8475 (make, mawk, nawk, ranlib, yacc): Similarly, move to...
8476 * lib/autoconf/programs.m4: here.

8488 * lib/freeze.mk (autoconf_m4f_dependencies): Add autoscan.m4.
8489 (.m4.m4f): Don't pass --prepend-include, since that's done by
8490 tests/autom4te itself.
8491 * lib/autoscan/Makefile.am: Include freeze.mk.
8492 (autoscan.list): New target --this file is no longer a source.
8493 (autoscan.pre): New file.
8495 2002-09-28 Akim Demaille <akim@epita.fr>
8497 * bin/autoscan.in (@kinds): Make them singular.
8498 Adjust all uses.
8499 (&init_tables): When --debug, report the list of rules to ease
8500 tracking changes in autoscan.list.
8501 * lib/autoscan/autoscan.list (function): Strip comments, sort.
8503 2002-09-28 Akim Demaille <akim@epita.fr>

8514 * lib/autoscan/identifiers, lib/autoscan/makevars,
8515 * lib/autoscan/programs: Make the `kind' explicit, i.e., each
8516 `functions' line is now prefixed with `function:'.
8517 * bin/autoscan.in (&init_tables): Adjust.
8519 2002-09-28 Akim Demaille <akim@epita.fr>
8521 From now on, autoscan files must always map a macro name to a
8522 word: there is no `default' macro for autoscan.
8524 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8525 all.
8526 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8527 explicit.
8529 2002-09-28 Akim Demaille <akim@epita.fr>
8531 * bin/autoscan.in (%c_keywords): Remove.
8532 (&used): Keep only track of the words we might be interested in.

8563 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8564 Reported by Ralf Corsepius.
8565 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8567 2002-09-26 Akim Demaille <akim@epita.fr>
8569 Single suffix rules and seperated dependencies are not portable.
8571 * doc/autoconf.texi (Installation Directory Variables): Update.

8585 make handles suffix-rules differently from GNU make.
8587 * bin/Makefile.am (SUFFIXES, .in): Remove.
8588 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):

8591 2002-09-16 Akim Demaille <akim@epita.fr>
8593 i960 compilers create `b.out' files by default.
8594 Reported by Ralf Corsepius.

8615 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest

8617 Suggested by Guido Draheim.
8619 2002-09-13 Akim Demaille <akim@epita.fr>
8621 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8622 (chdir_init) might hang when stat'ing mounted directories.

8625 2002-09-12 Akim Demaille <akim@epita.fr>
8627 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8628 the lists.
8630 2002-09-12 Akim Demaille <akim@epita.fr>
8632 * doc/autoconf.texi (Defining Symbols): Present two different
8633 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the

8638 * doc/autoconf.texi: Review grammar and punctuation.

8643 grammatical typos.
8644 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8645 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8646 is obsolescent.
8648 2002-09-11 Akim Demaille <akim@epita.fr>
8650 * doc/autoconf.texi (Questions): Rename as...

8666 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8667 `duplicates', since the algorithm was too naive and could keep
8668 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8669 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8670 Reported by Ralf Corsepius.

8681 directory definition.
8682 Reported by Andreas Schwab and Jim Meyering.
8684 2002-09-06 Akim Demaille <akim@epita.fr>

8687 precious variables are.
8688 Suggested by Pontus Skoeld.
8690 2002-09-05 Akim Demaille <akim@epita.fr>
8692 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8693 (ifnames, autoscan, autom4te): Since we don't only depend on
8694 configure.ac variables (such as VERSION etc.), but also on prefix
8695 and so forth, depend on Makefile, not configure.ac.
8696 Reported by Alexandre Duret-Lutz.
8697 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8699 2002-09-05 Kevin Ryde <user42@zip.com.au>
8701 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes

8719 * configure.ac: Bump to 2.53d.

8721 as of today, on Automake's team suggestion.
8723 2002-09-03 Akim Demaille <akim@epita.fr>
8725 Version 2.53c.
8727 2002-09-02 Akim Demaille <akim@epita.fr>

8736 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8737 Also, tweak grammar: s/make sure to/be sure to/.
8739 2002-09-02 Paul Eggert <eggert@twinsun.com>
8741 * doc/autoconf.texi (Limitations of Builtins): Explain why logical

8746 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8747 Reported by Raja R. Harinath.
8748 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8749 * bin/autoupdate.in: Use error instead of die.
8751 2002-09-01 Paul Eggert <eggert@twinsun.com>
8753 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8754 ordinary shell concatenation rather than echo+tr+sed command that
8755 runs afoul of a long-line-related sed bug in Solaris 8.
8757 * bin/autoheader.in (parse_args): --warning -> --warnings.
8759 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8760 stdout, as traditional "ls" does.
8761 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8762 _AC_COMPILER_EXEEXT_O): Likewise.
8763 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8765 * bin/autoconf.as: Add --prepend-include option. This patch was
8766 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8767 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8769 * bin/autoconf.in, configure: Regenerate.
8771 * doc/autoconf.texi (Special Shell Variables): Mention
8772 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8774 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8775 MAILPATH and set PS1, PS2, PS4 to default values, to work
8776 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8777 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8778 the Autoconf documentation specifies; fall back to "unset" only if
8779 this fails. Use a shell for-loop for this rather than an m4 loop,
8780 to shorten the output script.
8782 2002-08-30 Paul Eggert <eggert@twinsun.com>
8784 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8785 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8786 for the CDPATH problem. Document PWD.
8787 (Limitations of Builtins): Document the problem that "cd $foo" and
8788 "ls $foo" may refer to different directories in shells conforming
8789 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8790 example, since the old example is now out of date.
8792 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8793 FOO" and "ls FOO" talk about different directories; this catches
8794 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8795 spaghetti.
8797 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8798 of rolling our own unset.
8799 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8800 in practice we needn't worry about CDPATH if unset doesn't work.
8802 * Makefile.in, aclocal.m4, bin/Makefile.in,
8803 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8804 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8805 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8806 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8807 tests/Makefile.in: Regenerate with Automake 1.6.3.
8809 * config/config.guess, config/config.sub, config/mkinstalldirs:
8810 Update.
8812 * configure: Regenerate with self.
8814 2002-08-30 Kevin Ryde <user42@zip.com.au>
8816 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8817 default output.
8819 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8821 * bin/autom4te.in (Request::load): Correctly test for "do" read
8822 failure.
8824 2002-08-29 Akim Demaille <akim@epita.fr>
8826 * lib/Autom4te/General.pm (&xqx): New.
8827 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8828 hand, which is not portable.
8829 (&error): New.
8830 * bin/autom4te.in: Use them.
8831 Use &error instead of die.
8832 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8833 Adjust.
8835 2002-08-17 Paul Eggert <eggert@twinsun.com>
8837 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8838 default list of compilers to try, since it was long ago superseded
8839 by the ksh fc builtin. Suggested by Steven G. Johnson.
8841 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8843 * doc/autoconf.texi (Invoking autom4te): End the option table,
8844 fixing a bug introduced by the previous patch.
8845 (Limitations of Make): Add a 'target lookup' subentry in the
8846 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8848 2002-07-29 Mark D. Roth <roth@feep.net>
8850 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8851 options and use $AUTOM4TE_PATH.
8852 * doc/autoconf.texi: Remove documentation of autom4te
8853 --include-envvar and --site-macro-subdir options and document
8854 use of $AUTOM4TE_PATH.
8855 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8856 arguments from each language section.
8858 2002-07-29 Paul Eggert <eggert@twinsun.com>
8860 * doc/install.texi: Include copyright symbol in copyright notice.
8862 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8863 Replace with:
8864 (AM_MAKEINFOFLAGS): New macro.
8865 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8866 * Makefile.am (INSTALL): Use the new macros.
8867 Use -o rather than --output, since "missing" does not grok --output.
8869 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8871 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8872 comments do not always work. Never trust the exit status of
8873 `make -k'.
8875 2002-07-24 Kevin Ryde <user42@zip.com.au>
8877 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8878 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8880 2002-07-23 Paul Eggert <eggert@twinsun.com>
8882 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8883 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8884 apparently treats PATH="nonexistent" as if it contained ".".
8885 Bug reported by Stefan `Sec' Zehl.
8887 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8889 * doc/autoconf.texi (Limitations of Make): Mention the special
8890 handling of the obj/ directory by BSD make.

8906 2002-07-18 Akim Demaille <akim@epita.fr>
8908 Version 2.53b.
8910 2002-07-18 Akim Demaille <akim@epita.fr>
8912 * config/config.guess, config/config.sub: Update.
8914 2002-07-18 Akim Demaille <akim@epita.fr>
8916 Handle LIBOBJS and LTLIBOBJS once for all, including Libtool's and
8917 Automake's parts.

8920 * lib/autoconf/status.m4 (AC_OUTPUT_COMMANDS_PRE): Call it.

8923 2002-07-18 Akim Demaille <akim@epita.fr>,
8924 Alexandre Duret-Lutz <duret_g@epita.fr>
8926 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install

8942 * lib/Autom4te/General.pm (find_file): Browse the directories in
8943 the order they are given.

9004 2002-07-02 Alexandre Duret-Lutz <duret_g@epita.fr>
9006 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
9007 bin/autoupdate.in, bin/ifnames.in, lib/Autom4te/General.pm,
9008 lib/Autom4te/Struct.pm, lib/Autom4te/XFile.pm: Add local variables
9009 so that Emacs setups GNU style for perl-mode and cperl-mode.
9011 2002-06-27 Paul Eggert <eggert@twinsun.com>
9013 * config/install-sh: Quote $src. Prefer || to test's -o option,
9014 as per "Limitations of Builtins".
9015 * tests/atspecific.m4 (AT_CHECK_ENV): Likewise, for && vs test -a.
9016 * tests/semantics.at (AC_C_BIGENDIAN): Likewise.
9018 * tests/mktests.sh: Use grep instead of fgrep, as per
9019 "Limitations of Builtins".
9021 2002-06-15 Paul Eggert <eggert@twinsun.com>
9023 * tests/wrapsh.as (AUTOCONF, AUTOHEADER, AUTOM4TE, AUTOM4TE_CFG,
9024 autom4te_perllibdir): Set to top build dir or src dir as appropriate,
9025 so that we consistently test the just-built programs.
9026 * tests/wrappl.as: Likewise.
9028 2002-06-12 Paul Eggert <eggert@twinsun.com>
9030 * bin/autoconf.as (AUTOM4TE): Default to a fully qualified path
9031 name, so that symlinks to 'autoconf' work properly. Bug reported
9032 by Bruno Haible.
9033 * bin/autoheader.in (AUTOM4TE): Likewise.
9034 * bin/autoreconf.in (autoconf, autoheader): Likewise.
9035 * bin/autoscan.in (autom4te): Likewise.
9036 * bin/autoupdate.in (autom4te): Likewise.
9038 * lib/autoconf/functions.m4 (_AC_LIBOBJ_FNMATCH): Also check for
9039 btowc, to fix a portability bug with diffutils-2.8.2/lib/fnmatch.c
9040 on Solaris 2.5.1.
9042 2002-06-11 Andreas Schwab <schwab@suse.de>
9044 * doc/autoconf.texi: Add more dir entries.
9046 2002-06-10 Alexandre Duret-Lutz <duret_g@epita.fr>
9048 * bin/autom4te.in ($cache): Don't define using `$me', the name
9049 of the cache should not depend on the name under which autom4te
9050 was installed.
9052 2002-06-07 Akim Demaille <akim@epita.fr>
9054 * tests/tools.at (autoconf: forbidden tokens, basic)
9055 (autoconf: forbidden tokens, exceptions): Adjust to the change of
9056 words in autom4te.in.
9058 2002-06-07 Peter Eisentraut <peter_e@gmx.net>
9060 * lib/autoconf/c.m4 (AC_LANG_PROGRAM(C)): Use
9061 _AC_LANG_PROGRAM_C_F77_HOOKS.
9063 2002-06-07 Akim Demaille <akim@epita.fr>
9065 * lib/autoconf/functions.m4 (AC_REPLACE_FUNC_FNMATCH): Typo,
9066 rename as...
9067 (AC_REPLACE_FNMATCH): this.
9068 * tests/mktests.sh (exclude_list): Exclude AC_REPLACE_FNMATCH,
9069 AC_FUNC_FNMATCH_GNU.
9071 2002-06-07 Akim Demaille <akim@epita.fr>
9073 * doc/autoconf.texi (Systemology): Point to Tru64 docs, and the
9074 Rosetta Stone for Unix.
9076 2002-06-07 Akim Demaille <akim@epita.fr>
9078 * bin/autom4te.in (warn_forbidden): When rejecting a token,
9079 suggest m4_pattern_allow.
9080 Suggested by Adam J. Richter.
9082 2002-06-07 Akim Demaille <akim@epita.fr>
9084 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Initialize
9085 ac_config_libobj_dir.
9086 (AC_CONFIG_LIBOBJ_DIR): New.
9087 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Split into...
9088 (_AC_FUNC_FNMATCH_IF, _AC_LIBOBJ_FNMATCH): these.
9089 Use ac_config_libobj_dir to find the replacement files.
9090 (AC_FUNC_FNMATCH, AC_FUNC_FNMATCH_GNU): Split into...

9094 * doc/autoconf.texi (Particular Functions, Generic Functions): Adjust.
9095 * tests/mktests.sh (ac_exclude_list): Don't check

9098 2002-06-06 Paul Eggert <eggert@twinsun.com>
9100 * lib/autoconf/status.m4 (_AC_OUTPUT_LINKS): Fall back on cp
9101 if ln doesn't work.
9102 * NEWS: Likewise.
9103 * doc/autoconf.texi (Configuration Links): Likewise.
9104 (Limitations of Usual Tools): Prefer $(LN_S) to ln -s || ln.
9106 2002-06-05 Paul Eggert <eggert@twinsun.com>
9108 * config/config.guess, config/config.sub, config/texinfo.tex:
9109 Update from masters.
9111 2002-05-29 Paul Eggert <eggert@twinsun.com>
9113 * bin/autom4te.in ($m4): Do not assume that egrep and fgrep exist.
9114 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Likewise.
9115 * lib/autoconf/general.m4 (_AC_RUN_LOG_STDERR, AC_EGREP_CPP):

9124 * tests/mktests.sh (egrep): New var; use it instead of plain egrep.
9126 * lib/autoconf/programs.m4 (AC_PROG_EGREP, AC_PROG_FGREP): New macros.
9127 * doc/autoconf.texi (Particular Programs): Document them.
9128 (Limitations of Usual Tools): Warn that egrep and fgrep may not exist.
9129 * NEWS: Likewise.
9131 2002-05-27 Paul Eggert <eggert@twinsun.com>
9133 * lib/autoconf/types.m4 (AC_TYPE_MBSTATE_T): New macro.
9134 * NEWS, doc/autoconf.texi (Particular Types): Document it.
9135 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): Require it
9136 instead of AC_MBSTATE_T, which never existed.
9138 2002-05-23 Akim Demaille <akim@epita.fr>
9140 * doc/autoconf.texi (Hosts and Cross-Compilation): Specify the
9141 version of Autoconf that is discussed.
9143 2002-05-22 Paul Eggert <eggert@twinsun.com>
9145 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove cf77 and cft77
9146 from the default list of compilers to try. Suggested by
9147 Kate Hedstrom.
9148 * NEWS: Document the above.
9149 * doc/autoconf.texi (Fortran 77 Compiler): Don't suggest cf77.
9151 2002-05-17 Paul Eggert <eggert@twinsun.com>
9153 * lib/autoconf/types.m4 (AC_CHECK_MEMBER): Work correctly even if
9154 the member is itself an aggregate. Bug reported by Sergey Poznyakoff.
9155 This improves on an earlier suggestion by H. Peter Anvin.
9157 2002-05-16 Paul Eggert <eggert@twinsun.com>
9159 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9160 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9161 Both macros now accept an optional source-dir arg.
9162 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9164 * NEWS: Document this.
9165 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9167 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9168 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,
9169 not for GNU extensions; this undoes part of the 2000-11-03 change,
9170 reverting to 2.13-compatible behavior.
9171 Add new optional argument DIR.
9172 (AC_FUNC_FNMATCH_GNU): New macro.
9174 * lib/autoconf/specific.m4 (AC_GNU_SOURCE): New macro.
9176 2002-05-08 Paul Eggert <eggert@twinsun.com>
9178 * lib/autoconf/headers.m4 (AC_HEADER_TIOCGWINSZ):
9179 Don't require AC_SYS_POSIX_TERMIOS. The test is unnecessary,
9180 and it causes a 'test' syntax error if it fails.
9181 Bug reported by Stephen Gildea.
9183 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9184 If prototypes are supported, use them to check this at compile-time,
9185 instead of trying to check it at run-time. If we must do a run-time
9186 check, assume that setvbuf is standard when cross-compiling, as
9187 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9188 Bug reported by Paul D. Smith.
9190 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9191 argument specifying location of getloadavg.c. This removes a
9192 FIXME. This idea was taken from Jim Meyering's implementation in
9193 textutils.
9194 * doc/autoconf.texi (Particular Functions): Document this.
9195 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9196 that's what the code does; this fixes a bug reported by
9197 Paul D. Smith.
9199 2002-05-03 Akim Demaille <akim@epita.fr>
9201 * bin/autoreconf.in (autoreconf): Rewrite to use Gettext's
9202 autopoint instead of gettextize.
9203 ($uses_alocal): Rename as...
9204 ($uses_aclocal): this.
9205 * doc/autoconf.texi (autoreconf Invocation): Adjust.
9206 Suggested by Bruno Haible.
9208 2002-05-03 Akim Demaille <akim@epita.fr>
9210 * lib/m4sugar/m4sugar.m4 (m4_map_sep): New.
9212 2002-04-29 Paul Eggert <eggert@twinsun.com>
9214 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9215 files to be 1 second older; just set them to be the same time.
9216 Also, sleep 1 second after the first aclocal, to work around
9217 problems with sub-second time stamps on the input files.
9219 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9221 * doc/autoconf.texi: Mention "set -e -x" lossage
9222 under node "Limitations of Builtins".
9224 2002-04-29 Akim Demaille <akim@epita.fr>
9226 * doc/install.texi: Better wording for setting variables when
9227 running configure.
9228 From Christian Cornelssen.
9230 2002-04-29 Akim Demaille <akim@epita.fr>
9232 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9233 of lack of $LINENO support, then the test will compare the $LINENO
9234 in testsuite vs. the lineno in the test file. This is wrong, of
9235 course.
9236 Be sure to protect it.
9237 Reported by Patrick Welche.
9239 2002-04-25 Akim Demaille <akim@epita.fr>
9241 * doc/autoconf.texi (Obsolete Macros): Typo.
9242 Reported by Vladimir Volovich.
9244 2002-04-25 Akim Demaille <akim@epita.fr>
9246 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9247 than some of the input files, hence, on the second run of aclocal,
9248 if some of its input are younger, make them older.
9249 Suggested by Paul Eggert.
9251 2002-04-25 Akim Demaille <akim@epita.fr>
9253 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.
9254 Thanks to Paul Eggert.
9256 2002-04-25 Akim Demaille <akim@epita.fr>
9258 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Let ac_subst_files
9259 and ac_subst_vars be sh variables containing the list of
9260 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9261 DEFAULT diversion.
9262 (_AC_INIT_PREPARE): Use them to log them.
9263 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9264 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9265 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in
9266 _AC_SUBST_FILES and _AC_SUBST_VARS.
9267 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Adjust.
9269 2002-04-24 Akim Demaille <akim@epita.fr>
9271 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9272 autoheader, so that automake does not complain about a missing
9273 config.h.in that was to be created.
9275 2002-04-23 Akim Demaille <akim@epita.fr>
9277 * bin/autoheader.in (parse_args): --warning takes an argument.
9278 Fixes PR/220.
9280 2002-04-22 Peter Eisentraut <peter_e@gmx.net>
9282 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Remove gmon.out
9283 and bb.out when cleaning up.
9285 2002-04-22 Akim Demaille <akim@epita.fr>
9287 Version 2.53a.
9289 2002-04-22 Akim Demaille <akim@epita.fr>
9291 * tests/m4sh.at (LINENO): Fix the Zsh skip pattern.
9293 2002-04-22 Akim Demaille <akim@epita.fr>
9295 * doc/autoconf.texi (Pretty Help Strings): Remove a spurious
9296 comma.
9297 Reported by Gregory Giannoni.
9299 2002-04-22 Akim Demaille <akim@epita.fr>
9301 * tests/m4sh.at (LINENO): Skip the test if LINENO cannot be unset.
9302 Fixes false failures on Darwin.
9304 2002-04-21 Paul Eggert <eggert@twinsun.com>

9308 lib/autoconf/status.m4, lib/m4sugar/m4sugar.m4, tests/m4sh.at,

9311 2002-04-20 Paul Eggert <eggert@twinsun.com>

9326 tests/atspecific.m4, tests/semantics.at, tests/torture.at:
9327 Minor spelling and grammar fixes.
9329 * doc/autoconf.texi: Follow the outline suggested in the GNU
9330 Sample Texts sections of the Texinfo 4.2 manual. Most
9331 importantly, this makes sure that the copyright notices appear in
9332 all output formats. You probably need Texinfo 4.2 to generate
9333 the manual now.
9335 Fix some bugs when using "$@" when there might be zero positional
9336 arguments in cases where this matters.
9338 * bin/autoconf.as: Rewrite so that the problem does not come up.

9356 * tests/c.at: We can't have zero arguments, so remove workaround
9357 that is not portable to Zsh.
9359 2002-04-19 Alexandre Duret-Lutz <duret_g@epita.fr>
9361 * bin/autoupdate.in (handle_autoconf_macros): Honor AU_DEFUNs
9362 from aclocal.m4 too.
9364 2002-04-12 Akim Demaille <akim@epita.fr>
9366 * tests/wrappl.as: New, M4sh precursor of wrappl.in.
9368 2002-04-10 Akim Demaille <akim@epita.fr>
9370 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Install the Zsh
9371 workaround for ${1+"$@"}.
9372 * doc/autoconf.texi (Shell Substitutions): Explain it.
9373 From Oliver Kiddle and Peter Stephenson.
9375 Have M4sh perform minimal shell sanitizing.
9377 * lib/m4sugar/m4sh.at (AS_SHELL_SANITIZE): Split the `_AS_PREPARE_*'
9378 part into...
9379 (_AS_PREPARE): this new macro.
9380 (AS_PREPARE): New.
9381 (AS_INIT): Invoke AS_SHELL_SANITIZE.
9382 * tests/m4sh.at (AT_DATA_LINENO): Use _AS_PREPARE.
9384 Adjust Autoconf and Autotest.
9386 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Don't invoke
9387 AS_SHELL_SANITIZE, AS_INIT did it, but invoke AS_PREPARE.
9388 * lib/autotest/general.m4 (AT_INIT): Likewise.
9389 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
9390 Invoke _AS_PREPARE (not AS_PREPARE) in addition to
9391 AS_SHELL_SANITIZE.
9393 Use this M4sh to generate Autoconf's shell scripts.
9395 * tests/wrapsh.as: New, precursor of wrapsh.in.
9396 * tests/Makefile.am: Include lib/freeze.mk to get the dependencies
9397 on Autotest and M4sh.
9398 ($(TESTSUITE)): Use $(autotest_m4f_dependencies).
9399 (wrapsh.in): New target.
9400 * bin/autoconf.as: New, precursor of autoconf.in.
9401 (autoconf.in): New target.
9403 2002-04-09 Alexandre Duret-Lutz <duret_g@epita.fr>

9406 with indented comments in rules.
9408 2002-04-09 Andreas Schwab <schwab@suse.de>
9410 * lib/autoconf/status.m4 (_AC_SRCPATHS): Handle empty
9411 ac_top_builddir when setting ac_abs_top_builddir.
9413 2002-04-06 Kevin Ryde <user42@zip.com.au>
9415 * doc/autoconf.texi (Systemology): Add link to Unix V7 online docs.
9416 (Portable Shell): Cross reference to Systemology.
9418 2002-04-05 Akim Demaille <akim@epita.fr>
9420 * bin/autoreconf.in (autoreconf): Be sure to accumulate the
9421 directories when descending in a SUBDIRS.
9422 Reported by Ezra Peisach.
9424 2002-04-04 Andreas Schwab <schwab@suse.de>
9426 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Only simplify if path
9427 contains no literal separators.
9429 2002-04-03 Akim Demaille <akim@epita.fr>
9431 * lib/autoconf/status.m4 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER)
9432 (_AC_CONFIG_COMMAND, _AC_CONFIG_LINK): New.
9433 Use dnl, not the KILL diversion.
9434 Extracted from...
9435 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_COMMANDS)
9436 (AC_CONFIG_LINKS): here.
9437 Adjust.
9438 Don't use the KILL diversion, as it kills spurious output, which
9439 results in failures being hidden.
9440 Use m4_defn where appropriate.
9441 (AC_CONFIG_IF_MEMBER): Kill the real bug: a spurious parenthesis
9442 after the second argument.
9443 Use m4_defn.
9444 * lib/autom4te.in (Autoconf, Autotest, M4sh): Don't pass --warning
9445 syntax, as it is provided by M4sugar.
9446 * tests/torture.at (Multiple AC_CONFIG_FILES): New.
9448 2002-04-03 Andreas Schwab <schwab@suse.de>
9450 * lib/m4sugar/m4sugar.m4 (m4_bmatch): Make sure m4_bregexp is not
9451 expanded if $# <= 2.
9453 * bin/autoreconf.in (autoreconf): Run automake after rerunning
9454 aclocal.
9456 2002-04-03 Akim Demaille <akim@epita.fr>
9458 * lib/autoconf/lang.m4 (_AC_COMPILER_OBJEXT_REJECT)
9459 (_AC_COMPILER_EXEEXT_REJECT): New.
9460 Also recognize *.bb and *.bbg as compilation byproducts.
9461 (_AC_COMPILER_EXEEXT_DEFAULT, _AC_COMPILER_EXEEXT_O)
9462 (_AC_COMPILER_OBJEXT): Use them.
9463 Fixes Debian #138666.
9465 2002-04-02 Peter Eisentraut <peter_e@gmx.net>
9467 Integrate AC_PROG_CC_STDC into AC_PROG_CC.
9469 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): Rename to _AC_PROG_CC_STDC.
9470 AU_DEFUN old name. Use _AC_COMPILE_IFELSE.
9471 (AC_PROG_CC): Call _AC_PROG_CC_STDC.
9472 (AC_C_INLINE): Do not require AC_PROG_CC_STDC.
9473 (AC_C_CONST): Same.

9477 * tests/mktests.sh (au_exclude_list): Add AC_PROG_CC_STDC and
9478 AC_C_CROSS.

9483 _AS_MKDIR_P_PREPARE.
9485 2002-03-28 Kevin Ryde <user42@zip.com.au>
9487 * lib/autoconf/c.m4 (AC_C_INLINE): Test with a typedef return value,
9488 to avoid versions of HP C which don't allow that.
9490 2002-03-27 Paul Eggert <eggert@twinsun.com>
9492 * lib/m4sugar/m4sh.m4 (_AS_BASENAME_PREPARE): New macro.
9493 (AS_SHELL_SANITIZE): Invoke it.
9494 (AS_BASENAME): AS_REQUIRE it, and use $as_basename.
9496 2002-03-26 Akim Demaille <akim@epita.fr>
9498 * doc/autoconf.texi (Portable Shell): Add pointers to FAQs.
9500 2002-03-26 Akim Demaille <akim@epita.fr>
9502 * doc/autoconf.texi (Introduction): The GNATS base moved.
9504 2002-03-25 Paul Eggert <eggert@twinsun.com>
9506 * tests/m4sh.at: Don't rely on "PATH=test:$PATH test-1" working
9507 as POSIX requires, as it doesn't work with Zsh.
9508 * doc/autoconf.texi (Assignments): Document the problem.
9510 2002-03-25 Alexandre Duret-Lutz <duret_g@epita.fr>
9512 * doc/autoconf.texi (Limitations of Make): Mention more issue
9513 about VPATH, overriding of macros in sub-makes, and handling of
9514 SHELL.
9516 2002-03-21 Paul Eggert <eggert@twinsun.com>
9518 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9519 problem with here-document buffer boundaries.
9521 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9522 when reinvoking the shell, to work around problems with installers
9523 who put strange things like "cd" commands in their environments.
9525 2002-03-19 Akim Demaille <akim@epita.fr>
9527 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.
9528 From Aaron Ucko.
9530 2002-03-19 Akim Demaille <akim@epita.fr>
9532 * bin/autoscan.in (scan_file): Specify the location in `&used'
9533 invocations.
9534 From Nicolas Joly.
9536 2002-03-19 Akim Demaille <akim@epita.fr>
9538 * doc/autoconf.texi: Adjust @code/@command, @xref/@ref usage.
9539 From Nishio Futoshi.
9541 2002-03-19 Akim Demaille <akim@epita.fr>
9543 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9545 2002-03-18 Paul Eggert <eggert@twinsun.com>
9547 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9548 (Limitations of Usual Tools): Add mkdir section.
9550 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9551 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9552 back on AS_DIRNAME to compute prefixes otherwise; this is
9553 roughly what mkinstalldirs does. That way, we need not have
9554 our own filename disassembler. The old disassembler did not
9555 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9557 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9558 Create at_test_all by a series of assignments,
9559 not by a single assignment of a long string. The latter causes ksh
9560 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9561 presumably because of a buffer overrun.
9563 2002-03-14 Paul Eggert <eggert@twinsun.com>
9565 * lib/autotest/general.m4 (at_times_skip):
9566 Renamed from at_times. Now a boolean.
9567 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9568 says 'times: not found'.
9570 2002-03-14 Akim Demaille <akim@epita.fr>
9572 * bin/autoreconf.in (&study_gettextize): New.
9573 (&autoreconf): Handle newest gettextize.
9574 Rerun aclocal if needed.
9575 Suggested by Andreas Schwab.
9577 2002-03-13 Akim Demaille <akim@epita.fr>
9579 * doc/autoconf.texi (Special Shell Variables): More about IFS.
9581 2002-03-13 Akim Demaille <akim@epita.fr>
9583 * doc/autoconf.texi (Header Portability): New.
9584 Add information about stdint.h and inttypes.h from Paul Eggert.
9586 2002-03-13 Akim Demaille <akim@epita.fr>
9588 * doc/autoconf.texi (Limitations of Usual Tools): Some about `cp
9589 -p'.
9590 From Bob Proulx.
9592 2002-03-12 Akim Demaille <akim@epita.fr>
9594 * lib/m4sugar/m4sh.m4 (AS_BASENAME_EXPR): AS_REQUIRE, not
9595 m4_require.
9597 2002-03-11 Andreas Schwab <schwab@suse.de>
9599 * configure.ac: Explicitly check for EMACS since AM_PATH_LISPDIR
9600 does not do it if --with-lispdir is given.
9602 2002-03-08 Akim Demaille <akim@epita.fr>
9604 Version 2.53.
9606 2002-03-08 Akim Demaille <akim@epita.fr>
9608 * doc/autoconf.texi (Subdirectories): Clarify that the
9609 subdirectory should exist.
9611 2002-03-08 Akim Demaille <akim@epita.fr>
9613 * Makefile.am (AUTOMAKE_OPTIONS): 1.6.
9615 2002-03-08 Akim Demaille <akim@epita.fr>
9617 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9618 aliases the actual variables, and modifications of the former
9619 affect the latter.
9621 2002-03-08 Akim Demaille <akim@epita.fr>
9623 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9624 because of C-c: have m4 output in tmp files, then mv them.
9626 2002-03-08 Akim Demaille <akim@epita.fr>
9628 * bin/autoconf.in, bin/autoheader.in, bin/autom4te.in,
9629 * bin/autoreconf.in, bin/autoscan.in, bin/autoupdate.in,
9630 * bin/ifnames.in: Copyright update.
9632 2002-03-08 Akim Demaille <akim@epita.fr>
9634 * doc/autoconf.texi (Invoking autom4te): New.
9636 2002-03-05 Akim Demaille <akim@epita.fr>
9638 * doc/autoconf.texi (Specifying Names): Clarification suggested by
9639 Kevin Ryde.
9641 2002-03-05 Akim Demaille <akim@epita.fr>
9643 Version 2.52i.
9645 2002-03-04 Akim Demaille <akim@epita.fr>
9647 * doc/autoconf.texi (AC_LIBOBJ vs. LIBOBJS): New.
9648 * lib/autoconf/general.m4 (AC_INIT): More informative error
9649 message for LIBOBJ.
9651 2002-03-04 Akim Demaille <akim@epita.fr>
9653 * lib/freeze.mk ($(build_libdir)/m4sugar/version.m4): New, for
9654 parallel builds.
9656 2002-03-04 Akim Demaille <akim@epita.fr>
9658 * doc/autoconf.texi (Transforming Names): Equality between target
9659 and host is irrelevant.
9660 (Specifying Names, Canonicalizing): Remove all references to the
9661 backward compatibility hooks. Rather, collect them all into...
9662 (Hosts and Cross-Compilation): this new section.
9663 * doc/install.texi (System Type): Ditto.
9664 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9665 that `--host' implies cross-compilation.
9667 2002-03-04 Akim Demaille <akim@epita.fr>
9669 * doc/autoconf.texi (Evaluation Macros): New.
9670 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9671 useless.
9672 (_m4_foreach): Define the variant with immediate evaluation so
9673 that it contains exactly the items, not an expression which
9674 evaluation is the current item.
9675 (m4_re_string, m4_re_word): Don't over quote them.
9677 2002-03-04 Akim Demaille <akim@epita.fr>
9679 Instead of having stacking `shift's evaluated at the end, let
9680 `foreach' loops immediately evaluate them.
9682 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9683 $*. This is the n-th time I change my mind, but hopefully this is
9684 the last...
9685 (m4_lquote): New.
9686 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9687 efficient.
9688 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9689 it was only a hack for m4_text_wrap.
9690 (m4_car2): Remove, replaced by...
9691 (m4_cdr): New.
9692 (_m4_foreach): Adjust.
9693 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9694 m4_bpatsubst for clarification.
9696 2002-03-04 Akim Demaille <akim@epita.fr>

9711 of messages.
9713 2002-02-28 Akim Demaille <akim@epita.fr>
9715 * lib/autotest/general.m4 (AT_INIT): Suggest a title to the

9724 * lib/autoconf/functions.m4 (AC_FUNC_SETPGRP): Fix the test.
9725 From Akinori Musha.
9727 2002-02-13 Alexandre Duret-Lutz <duret_g@epita.fr>
9729 * lib/Autom4te/XFile.pm (getline, getlines): New functions,
9730 translate \r\n to \n.
9732 2002-02-07 Akim Demaille <akim@epita.fr>

9736 2002-02-07 Akim Demaille <akim@epita.fr>
9738 Fix Autoconf PR/209.
9739 Also reported by Frank Denis.
9741 * lib/m4sugar/m4sh.m4 (_AS_PATH_WALK): Don't over quote.
9743 2002-02-07 Akim Demaille <akim@epita.fr>
9745 Fix Autoconf PR/207:
9746 AC_PREFIX_PROGRAM fails with dashed program names
9748 * lib/autoconf/general.m4 (AC_PREFIX_PROGRAM): Just use a fresh
9749 variable when looking for the prefix program.
9750 Now it also works for shell variables.
9752 2002-02-07 Akim Demaille <akim@epita.fr>
9754 * doc/autoconf.texi (Limitations of Builtins): More about
9755 case/esac.
9757 2002-02-06 Akim Demaille <akim@epita.fr>
9759 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Don't output empty
9760 case/esac, some shells don't support it.
9761 Reported by Zack Weinberg.
9762 * tests/torture.at (AC_CONFIG_COMMANDS with empty commands): New.
9764 2002-02-06 Akim Demaille <akim@epita.fr>
9766 * lib/autotest/general.m4 (AT_INIT): When handling --keywords, be
9767 sure not to introduce newlines in at_groups.
9768 * lib/autotest/Makefile.am (autotest.m4f): Typo.
9770 2002-02-06 Akim Demaille <akim@epita.fr>
9772 * tests/torture.at (Configuring subdirectories): Skip if aclocal
9773 is not available.
9775 2002-02-05 Paul Eggert <eggert@twinsun.com>
9777 * doc/autoconf.texi (Specific Compiler Characteristics):
9778 Describe HP-UX cc bug workaround more accurately.
9779 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast to long,
9780 not unsigned long.
9781 * tests/semantics.at (AC_CHECK_SIZEOF): Check non-GCC
9782 cross-compilers, too. This undoes some of the most recent change
9783 to this file.
9785 2002-02-05 Akim Demaille <akim@epita.fr>
9787 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,
9788 to make sure they are up to date when `check' is run.
9790 2002-02-05 Akim Demaille <akim@epita.fr>
9792 * doc/autoconf.texi (Making testsuite Scripts): Document
9793 package.m4.
9795 2002-02-05 Akim Demaille <akim@epita.fr>
9797 * lib/freeze.mk: New.
9799 2002-02-05 Akim Demaille <akim@epita.fr>
9801 Implement `autom4te --freeze'.
9803 * bin/autom4te.in (&freeze): New.
9804 * lib/autoconf/autoconf.m4, lib/autotest/general.m4,
9805 * lib/m4sugar/m4sh.m4: Don't include files given by autom4te.
9807 2002-02-05 Akim Demaille <akim@epita.fr>
9809 * bin/autom4te.in (&parse_args): Implement `frozen files are
9810 optional are the sum of the previous files on the command line'.
9811 Also, pass `--reload-state=' on them, so...
9812 (handle_m4): don't.
9813 * lib/autom4te.in (Autotest, Autoconf): Rely on M4sh.
9814 (M4sh): Rely on M4sugar.
9815 (Autotest, M4sh, M4sugar): Use frozen files.
9817 2002-01-31 Akim Demaille <akim@epita.fr>
9819 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Accept $4.
9820 * doc/autoconf.texi (Initializing configure): Adjust.
9822 2002-01-30 Akim Demaille <akim@epita.fr>
9824 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Map non
9825 alphanumeric to `-' instead of `_'.
9827 2002-01-30 Akim Demaille <akim@epita.fr>
9829 * tests/semantics.at (AC_CHECK_SIZEOF): Split into two tests: one
9830 for plain code, the other for cross-compilation code. The latter
9831 is now run with GCC only.
9832 * doc/autoconf.texi (Compilers and Preprocessors): New.
9834 2002-01-30 Akim Demaille <akim@epita.fr>
9836 * lib/autoconf/general.m4 (_AC_INIT_PACKAGE): Support pre-defined
9837 values.
9838 * doc/autoconf.texi (Initializing configure): Explain how to
9839 change AC_INIT default values.
9841 2002-01-29 Akim Demaille <akim@epita.fr>
9843 * tests/torture.at (Configuring subdirectories): Use configure.in,
9844 so that aclocal 1.4 works.
9845 Reported by Alexandre Duret-Lutz and Larry Schmitt.
9847 2002-01-28 Akim Demaille <akim@epita.fr>
9849 * doc/autoconf.texi (Writing testsuite.at): AT_CLEANUP no longer
9850 needs an argument.
9852 2002-01-28 Akim Demaille <akim@epita.fr>
9854 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9855 AUTOTEST_PATH *after* it was set.
9856 Don't put `.' in the PATH: the user should be precise and `./' if
9857 needed. In addition, given that the test suite does some `cd', if
9858 `.' is in the path, the `tested programs' sections will report
9859 programs found in the test suite's directory, while during the
9860 tests (performed in their own directory), these programs are no
9861 longer visible. In other words, the results is confusing and
9862 useless.
9863 * tests/m4sh.at: Adjust: don't rely on `.' being in the PATH.
9865 2002-01-24 Akim Demaille <akim@epita.fr>
9867 Version 2.52g.
9869 2002-01-24 Akim Demaille <akim@epita.fr>
9871 * bin/autoheader.in, bin/autoconf.in, bin/autoscan.in,
9872 * doc/autoconf.texi: Finally add Akim as an author.
9874 2002-01-24 Akim Demaille <akim@epita.fr>
9876 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Use PATH_SEPARATOR.
9877 (_AS_PATH_SEPARATOR_PREPARE): Don't expect $SHELL to be
9878 Bourne. Use /bin/sh.
9879 From Andreas Buening.
9881 2002-01-24 Akim Demaille <akim@epita.fr>
9883 * config/config.guess, config/config.sub, config/texinfo.tex:
9884 Update from masters.
9886 2002-01-24 Akim Demaille <akim@epita.fr>
9888 * Makefile.am (AUTOMAKE_OPTIONS): 1.5b.
9889 * config/auxdir.m4, config/cond.m4, config/depend.m4,
9890 * config/init.m4, config/install-sh.m4, config/lispdir.m4,
9891 * config/missing.m4, config/sanity.m4, config/select.m4,
9892 * config/strip.m4: Remove, to ease sync'ing with any version of
9893 Automake.
9895 2002-01-24 Akim Demaille <akim@epita.fr>
9897 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS)
9898 (_AC_INIT_PREPARE): Support -n as --no-create, as documented.
9899 Reported by Geir Ove Myhr.
9901 2002-01-21 Akim Demaille <akim@epita.fr>
9903 * lib/autoconf/functions.m4 (AC_FUNC_MMAP): #Undef malloc.
9905 2002-01-21 Akim Demaille <akim@epita.fr>
9907 * lib/Autom4te/General.pm (getopt): Use a more GNUish error
9908 message on invalid options.
9909 * bin/autom4te.in (parse_args): Don't use
9910 Autoconf::General::getopt with non valid options.
9912 2002-01-17 Jim Meyering <meyering@lucent.com>
9914 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Initialize
9915 $ac_cv_exeext so we don't use an old, invalid, cached value.
9917 2002-01-11 Akim Demaille <akim@epita.fr>
9919 * lib/autoconf/functions.m4 (AC_FUNC_STRNLEN): New, from Jim
9920 Meyering.
9921 * doc/autoconf.texi (Function Portability): Document the strnlen
9922 limitation.

9926 2002-01-06 Akim Demaille <akim@epita.fr>
9928 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Don't create
9929 package.m4, since is really depends upon configure.ac, not
9930 configure.
9931 * doc/autoconf.texi (testsuite Scripts): Adjust.
9932 * tests/Makefile.am (package.m4): New.
9933 EXTRA_DIST it since its a source.
9935 2002-01-06 Akim Demaille <akim@epita.fr>
9937 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Move the AC_SUBST
9938 of PACKAGE_NAME, PACKAGE_TARNAME, PACKAGE_VERSION, PACKAGE_STRING,
9939 and PACKAGE_BUGREPORT from here...
9940 (_AC_INIT_DEFAULTS): to here, since it is unrelated to the
9941 arguments.
9942 (_AC_INIT_PREPARE): AC_DEFINE these symbols.
9943 * lib/autotest/general.m4: Use AT_PACKAGE_*, not PACKAGE_*.
9944 (AT_INIT): No longer catch `^PACKAGE_(BUGREPORT|STRING)$'.
9945 * tests/tools.at (autoheader): Adjust.
9946 * tests/atspecific.m4 (AT_CHECK_DEFINES): Adjust.
9948 2002-01-06 Akim Demaille <akim@epita.fr>

9952 2002-01-03 Akim Demaille <akim@epita.fr>
9954 * doc/autoconf.texi (Output): Improved wording regarding use of
9955 AC_OUTPUT.
9956 From Olly Betts.
9958 2001-12-18 Kevin Ryde <user42@zip.com.au>
9960 * doc/autoconf.texi (Function Portability): Add notes on sscanf
9961 sometimes needing writable input.
9963 2001-12-17 Jim Meyering <meyering@lucent.com>
9965 * doc/autoconf.texi (New Macros): Tweak wording.
9967 2001-12-14 Akim Demaille <akim@epita.fr>
9969 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): We cleaning up the
9970 trailing files, don't apply `-rf' to files which might not be
9971 created by configure (core, core.*, and *.core), but just `rm -f'.
9972 Suggested by Jonathan Kamens.
9974 2001-12-14 Aaron M. Ucko <amu@alum.mit.edu>
9976 * lib/autoconf/general.m4: Avoid duplicates in `$ac_configure_args'.
9978 2001-12-14 Akim Demaille <akim@epita.fr>
9980 * Makefile.am (MAINTAINERCLEANFILES): Remove configure.
9982 2001-12-13 Peter Eisentraut <peter_e@gmx.net>
9984 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename buildpath to
9985 abs_builddir, top_buildpath to abs_top_builddir, srcpath to
9986 abs_srcdir, top_srcpath to abs_top_srcdir.
9987 (_AC_OUTPUT_FILES): Adjust.
9988 * NEWS, doc/autoconf.texi, lib/autoconf/autotest.m4,
9989 * tests/atspecific.m4, tests/autoreconf.in, tests/tools.at,
9990 * tests/wrappl.in, tests/wrapsh.in: Adjust.
9992 2001-12-12 Steven G. Johnson <stevenj@alum.mit.edu>
9994 * lib/autoconf/fortran.m4 (_AC_PROG_F77_V_OUTPUT): Fix failed
9995 C/Fortran linking on HP/UX, by extracting the Fortran library
9996 search path from the LPATH line in the $F77 -v output.
9998 2001-12-12 Kevin Ryde <user42@zip.com.au>
10000 * doc/autoconf.texi (File Descriptors): Use a clearer layout for the
10001 forbidden file descriptors table.
10003 2001-11-26 Akim Demaille <akim@epita.fr>
10005 * bin/autoscan.in (%c_keywords): Build it at top level.
10006 Map to 1 in order to simplify its uses.
10008 2001-11-26 Akim Demaille <akim@epita.fr>
10010 * bin/autoscan.in (&scan_c_file, &scan_sh_file, &scan_makefile):
10011 Remove $filepath, useless.
10012 (&scan_makefile): Don't remove the $(FOO), ${FOO} and @FOO@
10013 variables, they are really part of the tokens.
10014 Split the input line on spaces and then look for tokens.
10015 Now autoscan ceases to ask for AC_PROG_LEX for the package Bison
10016 because of `lex$U.$(OBJEXT)'.
10017 (&scan_files): Use "@list" instead of join.
10018 * doc/Makefile.am (CLEANFILES): Add *.fns.
10020 2001-11-26 Akim Demaille <akim@epita.fr>
10022 * tests/autoreconf.in, tests/autom4te.in, tests/autoupdate.in:
10023 Remove, replaced by...
10024 * tests/wrappl.in: Be common for all the Perl executables.
10025 In particular autoscan and autoheader want -I.
10026 * configure.ac: Adjust.
10027 * lib/autoscan/headers: errno.h is portable.
10029 2001-11-26 Akim Demaille <akim@epita.fr>
10031 * bin/autoscan.in (used): New.
10032 Use it.
10034 2001-11-26 Akim Demaille <akim@epita.fr>
10036 * bin/autoscan.in (&scan_c_file): Better parsing of CPP
10037 directives.
10038 (&scan_sh_file): Remove a duplicate pattern.
10039 (&check_configure_ac): Use long options.
10040 * lib/autoscan/headers (alloca.h): Check with AC_FUNC_ALLOCA.
10042 2001-11-26 Akim Demaille <akim@epita.fr>
10044 * bin/autoscan.in (scan_c_file): Fix the handling of C comments.
10045 Before, having a line containing the opening of a multi line
10046 comment made the whole line be ignored.
10048 2001-11-26 Akim Demaille <akim@epita.fr>
10050 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10051 (testsuite Scripts): Be one of its subsection.
10052 (Autotest Logs): New.
10054 2001-11-26 Akim Demaille <akim@epita.fr>
10056 Test groups are now run two directories deeper.
10058 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10059 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10060 at_top_builddir.
10061 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10062 top_srcdir, builddir and top_builddir.
10063 Use `at_*dir' relatively to the directory containing the
10064 suite, use `*dir' when relatively to the current group dir.
10066 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10068 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10069 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10070 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10071 spelling errors.
10073 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10075 * doc/autoconf.texi (Using System Type): Add an example of `case
10076 $host' usage so people quit using `case $target' everywhere.
10078 2001-11-22 Akim Demaille <akim@epita.fr>
10080 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10081 spotted by Jim Meyering.
10083 2001-11-16 Paul Eggert <eggert@twinsun.com>
10085 This patch implements a `long double' suggestion by Oliver Kiddle.
10087 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10088 static, to catch errors if the value isn't known at compile-time
10089 and the compiler supports dynamic arrays. Change its name from
10090 `_array_' to `test_array' to avoid potential name clashes.
10091 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10092 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10093 better than double. Catch a bug in GCC 2.95.2 x86.
10094 * doc/autoconf.texi (C Compiler): Document the above.
10095 * NEWS: Likewise.
10097 2001-11-13 Akim Demaille <akim@epita.fr>
10099 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10100 hand.
10101 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10103 2001-11-13 Akim Demaille <akim@epita.fr>
10105 * lib/autotest/general.m4 (AT_INIT): After having run the test
10106 group, go back to the initial directory, not to at_suite_dir.
10108 2001-11-13 Akim Demaille <akim@epita.fr>
10110 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10111 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10112 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10113 option.
10114 (AT_CHECK_CONFIGURE): Use absolute paths.
10115 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10116 The problem is still the old one: there is no means in M4 (that I
10117 know about) to create a defining macro, because there is no means
10118 to create `$1' etc., therefore, the defining macro ``swallows''
10119 all the arguments meant to the defined macro.
10121 2001-11-13 Akim Demaille <akim@epita.fr>
10123 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10124 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10125 configure.ac.
10126 * tests/aclocal.m4: Remove, as it is no longer used.
10128 2001-11-13 Akim Demaille <akim@epita.fr>
10130 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10131 variable names when referring to a single test group, or to
10132 `suite' when referring to the whole test suite.
10133 `at_last_test' is removed: m4 compute at_format itself.
10134 (at_stdout, at_stder1, at_stderr): New variables.
10135 (AT_CHECK): Use them.
10137 2001-11-13 Akim Demaille <akim@epita.fr>
10139 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10140 in PATH.
10141 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10142 Do it as soon as a test fails, don't wait till the end of the test
10143 suite.
10144 Don't remove $as_me.[0-9]*, since these files no longer exist.
10146 2001-11-13 Akim Demaille <akim@epita.fr>
10148 * tests/tools.at: Use absolute paths, since we are no longer run
10149 in place.
10151 2001-11-13 Akim Demaille <akim@epita.fr>
10153 Now that tests are running in their own private dir, there is no
10154 need to list the files to remove at the end of tests groups.
10156 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10157 (AT_data_files, at_data_files): Remove.
10158 (AT_CLEANUP, AT_DATA): Simplify.
10159 (AT_INIT): Adjust.
10160 Remove the group dir if !debug && !failed.
10161 * tests/atspecific.m4: Adjust.
10163 2001-11-13 Akim Demaille <akim@epita.fr>
10165 Start a new layout for Autotest: `testsuite' creates
10166 `testsuite.dir' in which the at-check-line etc. files are to be
10167 found, and `testsuite.dir/003' where the test group 3 is run.
10169 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10170 at_check_line_file, at_format, at_test_normalized, at_group_dir
10171 are new variables.
10172 Create the directories.
10173 Use absolute paths for at- files.
10174 (AT_CHECK): Adjust.
10176 2001-11-11 Michael Matz <matz@kde.org>
10178 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10179 (m4_car2): New.
10180 (m4_car): Properly quote arguments.
10182 2001-11-13 Akim Demaille <akim@epita.fr>
10184 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10185 with stricter rules on LIBOBJS.
10187 2001-11-12 Paul Eggert <eggert@twinsun.com>
10189 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10190 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10191 __PROTOTYPES too.
10193 2001-11-12 Akim Demaille <akim@epita.fr>
10195 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10197 2001-11-12 Akim Demaille <akim@epita.fr>
10199 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10200 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10201 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10202 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10203 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10204 specify to what the macro should be defined (typically to 1).
10206 2001-11-12 Akim Demaille <akim@epita.fr>
10208 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10209 From Jim Meyering.
10211 2001-11-12 Akim Demaille <akim@epita.fr>
10213 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10214 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10215 definition used by Automake where LEX is +/- "${missing} lex" and
10216 `missing' itself contains variables.
10218 2001-11-12 Akim Demaille <akim@epita.fr>
10220 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10221 Now that M4sh pushes BODY, the comments were output at the end of
10222 the test suites.
10224 2001-11-08 Akim Demaille <akim@epita.fr>
10226 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10227 that we can trace macros from aclocal.m4.
10228 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10229 obsoleted, and redirect to the former anyway.
10230 Reported by Ralf Corsepius.
10232 2001-11-08 Akim Demaille <akim@epita.fr>
10234 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10235 processed only if present.
10236 * tests/torture.at (Configuring subdirectories): Use autoreconf
10237 instead of successive calls to autoconf.
10238 Add a nonexistent subdirectory to exercise the patch above.
10239 Reported by Ralf Corsepius.
10241 2001-11-08 Kevin Ryde <user42@zip.com.au>
10243 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc

10252 (handle_output): Use it.
10253 Read m4_pattern_forbid with messages.
10255 2001-11-05 Akim Demaille <akim@epita.fr>
10257 * bin/autom4te.in (--normalize): Remove.
10258 * lib/autom4te.in: Adjust.
10260 2001-11-05 Akim Demaille <akim@epita.fr>
10262 * tests/Makefile.am (testsuite): Rename this target as...
10263 ($(TESTSUITE)): this.
10264 From Nicolas Joly.
10266 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10268 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10269 the --prefix option, also remove it's argument.
10271 2001-11-05 Akim Demaille <akim@epita.fr>
10273 * doc/autoconf.texi (testsuite Invocation): Update.
10274 (Writing testsuite.at): Update.

10282 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10283 (&file_name_is_absolute): New, wrappers around routines from
10284 File::Spec.
10285 Use and export them.
10286 (&find_configure_ac): Optionally take a directory where to look at.
10287 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10288 the arguments.
10289 Default @ARGV to `.', not find_configure_ac.
10290 (&autoreconf): Argument is a directory.

10294 2001-11-03 Akim Demaille <akim@epita.fr>
10296 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10297 (@export_forward_subs): New.
10298 Add basename, dirname, and fileparse.
10299 (@EXPORT): Adjust.
10300 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10301 Don't look for aclocal flags if we already know aclocal is not
10302 used.
10303 Move aclocal.m4t only if it exists.
10304 Reported by Ezra Peisach.
10306 2001-11-03 Akim Demaille <akim@epita.fr>
10308 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10309 passed on command line, defaulting to ./configure.ac if present.
10310 (&maybe_autoreconf, File::Find): Remove, unused.
10311 (&autoreconf): If autoconf is not used, don't try to trace.
10313 2001-11-02 Akim Demaille <akim@epita.fr>
10315 * configure.ac: Bump to 2.52g.
10317 2001-11-02 Akim Demaille <akim@epita.fr>
10319 Version 2.52f.
10321 2001-11-02 Akim Demaille <akim@epita.fr>
10323 * config/config.guess, config/config.sub, doc/standards.texi:
10324 * config/lispdir.m4: Update from masters.
10325 * configure.ac: Bump to 2.52f.
10327 2001-11-02 Akim Demaille <akim@epita.fr>
10329 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10330 Don't run aclocal when aclocal.m4 is not from aclocal.
10331 From Ezra Peisach.
10332 Don't run libtoolize and gettextize if --install is not given.
10334 2001-11-01 Paul Eggert <eggert@twinsun.com>
10336 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10337 be invoked before _AS_LINENO_PREPARE.
10338 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10339 than character ranges.
10341 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10342 invoking AS_BASENAME. Set the locale variables to 'C' if
10343 possible, as POSIX requires this to get the traditional
10344 behavior.
10345 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10347 2001-10-31 Paul Eggert <eggert@twinsun.com>
10349 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10350 with {}, as that triggers a bug in Bash 2.05.
10352 (_AS_LINENO_PREPARE): Use Sed rather than
10353 Awk. Fix the sed prepass to work even if there are multiple
10354 instances of $LINENO on the same line. Do not substitute for
10355 other variables like $LINENOT. Do not check file dates; such a
10356 check is unreliable on sufficiently fast machines, and removing
10357 the check makes the code simpler and more reliable. Check for
10358 output and chmod failures.
10360 * doc/autoconf.texi (Special Shell Variables): Document
10361 the above.
10363 2001-10-31 Akim Demaille <akim@epita.fr>
10365 * tests/Makefile.am (atconfig): Remove this target, Automake
10366 handles it now.
10368 2001-10-31 Akim Demaille <akim@epita.fr>
10370 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10371 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10372 provided, while it is optional.
10373 * configure.ac: Adjust.
10375 2001-10-26 Paul Eggert <eggert@twinsun.com>
10377 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10378 lib/Autom4te/Struct.pm:
10379 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10380 with 5.005_02.
10382 * doc/autoconf.texi (Special Shell Variables): Document some
10383 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10385 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10386 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10387 eval $LINENO is not portable in practice.
10389 2001-10-24 Akim Demaille <akim@epita.fr>
10391 * lib/Autom4te/General.pm (backname): New.
10393 2001-10-24 Akim Demaille <akim@epita.fr>
10395 * m4/: Remove, merged into...
10396 * config/: here.
10398 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10400 * doc/autoconf.texi (Shellology): Mention the problems with bash
10401 2.05's use of ANSI quoting in its `set' builtin.
10403 2001-10-22 Paul Eggert <eggert@twinsun.com>
10405 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10406 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10407 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10408 POSIX decided to standardize on the int flavor of strerror_r.
10409 Always do char* test, as there's no reason not to.
10410 Assign to a char* var, to catch strerror_r that returns int*.
10412 * doc/autoconf.texi (Particular Functions):
10413 Document the above changes. Also, document the fact that
10414 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10416 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10418 2001-10-20 Akim Demaille <akim@epita.fr>
10420 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10421 the executable was missing from the log.

10425 * lib/Autom4te/General.pm (&update_file): If destination is
10426 unchanged, remove the source.
10427 (&up_to_date_p): Don't be verbose, be debug.
10428 * bin/autoreconf.in: No longer support --m4dir.
10429 (&autoreconf): Display the full path of the configure.ac we are
10430 studying.
10431 Trace it only once.
10432 Be sure to honor --force with gettextize.
10433 Always run aclocal.
10434 * doc/autoconf.texi: Adjust.
10436 2001-10-20 Akim Demaille <akim@epita.fr>
10438 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10439 Remove, dead.
10440 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10441 `intl' is already present, as it refuses unless --force.
10442 (&parse_args): Use -I, --include instead of the old Autoconf
10443 options.
10444 ($localdir, $autoconf_dir): Remove.
10445 (@include): New.
10446 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10448 2001-10-19 Jens Petersen <petersen@redhat.com>

10456 file in @configure_input@.
10457 Don't mention `automatically' in addition to `generated'.
10458 * tests/torture.at (#define header templates): Adjust.
10460 2001-10-19 Akim Demaille <akim@epita.fr>
10462 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10463 comment, explain how to install automatic mode selection.
10464 From Russ Allbery.
10466 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10468 * bin/autoreconf.in (autoreconf): Display the path to the
10469 configure.ac being studied.
10471 2001-10-18 Paul Eggert <eggert@twinsun.com>
10473 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10474 long, to work around a bug in the HP C compiler version HP92453-01
10475 B.11.11.23709.GP.
10477 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10478 (AS_BASENAME_EXPR): New macro.
10479 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10480 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10481 and fall back on 'sed' only if the other two fail. This makes
10482 AS_BASENAME act more like AS_DIRNAME.
10483 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10484 contains white space.
10485 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10486 Use AS_DIRNAME, since I think it's now DOS-friendly.
10487 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10488 Allow "dirname //FOO" to return either / or //, as POSIX allows
10489 either behavior.

10493 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize

10495 From Eric Sharkey.

10499 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10500 m4_define, since...

10618 * tests/tools.at (AT_DATA_FORBIDDEN): New.

10629 empty, and if we can find a shell that does support LINENO,
10630 then set CONFIG_SHELL to that shell and then re-execute
10631 ourselves with CONFIG_SHELL.
10633 2001-10-05 Paul Eggert <eggert@twinsun.com>
10635 * tests/Makefile.am (clean-local): Don't invoke $(TESTSUITE) if it
10636 doesn't exist. Remove *.tmp, as a .tmp file is created during the

10639 2001-10-05 Akim Demaille <akim@epita.fr>
10641 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Look in the path

10663 (_AS_LINENO_PREPARE): Preserve the exit status of $0.lineno.
10664 From Paul Eggert.
10666 2001-10-04 Akim Demaille <akim@epita.fr>
10668 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use a portable
10669 combination of Awk and sed to replace $LINENO.
10671 2001-10-02 Paul Eggert <eggert@twinsun.com>
10673 * doc/autoconf.texi (Limitations of Builtins): You can't use
10674 "source"; it's not portable. Remove confusing and
10675 somewhat-incorrect example involving "." and "/".
10677 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): "source" -> ".", for
10678 compatibility with POSIX shells.
10680 2001-10-02 Akim Demaille <akim@epita.fr>
10682 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Just source 40.lineno
10683 instead of exec'ing to preserve $0 and $@.
10685 2001-10-01 Akim Demaille <akim@epita.fr>
10687 * tests/testsuite (AT_INIT) <at_pass_list>: New.
10688 Don't run twice the same test.

10706 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS):
10707 Don't use nested parenthesization. This patch was originally
10708 suggested to bug-autoconf by Philippe De Muyter on 2000-05-28,
10709 but somehow it didn't get incorporated then.
10710 * doc/autoconf.texi (Limitations of Usual Tools):
10711 Clarify remark about sed and nested parenthesization.
10713 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF):
10714 Report an error if the size cannot be determined even though
10715 the type exists.
10716 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10717 Check for `expr' arithmetic overflow, and for compilation failure,
10718 and invoke a new argument $4 if either is discovered.
10719 This makes _AC_COMPUTE_INT_COMPILE more like _AC_COMPUTE_INT_RUN.
10720 (_AC_COMPUTE_INT): Pass IF-FAILS arg to _AC_COMPUTE_INT_COMPILE.
10722 2001-09-28 Akim Demaille <akim@epita.fr>

10730 * lib/autotest/general.m4 (AT_VICTIMS): Rename as...
10731 (AT_TESTED): this.
10732 (AT_INIT): More the wrapped section to where it will be expanded.
10733 Output `AT_tested' only when existing.
10734 Catch unexpanded PACKAGE_STRING and PACKAGE_BUGREPORT.
10736 2001-09-27 Akim Demaille <akim@epita.fr>
10738 Fix the passing of $? to ACTION-IF-FAILED in AC_TRY_RUN, that
10739 generates too many bug reports.
10741 * lib/autoconf/general.m4 (_AC_RUN_IFELSE): Pass the right exit
10742 status when executing the ACTION-IF-FALSE.
10743 * tests/base.at (AC_TRY_*): Rename as...

10750 * tests/c.at (Extensions, C keywords)
10751 (Broken/missing compilers, AC_PROG_CPP with warnings)
10752 (AC_PROG_CPP without warnings, AC_PROG_CPP via CC)
10753 (AC_PROG_CPP requires AC_PROG_CC): here and...
10754 * tests/fortran.at (GNU Fortran 77): there.
10755 * doc/autoconf.texi (autoconf Invocation): Fix the example:
10756 AC_TRY_RUN is about compilation, not shell commands.
10757 (Test Programs): AC_TRY_RUN works as used to be advertised.
10759 2001-09-27 Akim Demaille <akim@epita.fr>
10761 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix bugs spotted by
10762 Raja R Harinath:
10763 Be sure to detect when $LINENO always returns the same value.
10764 Look for the original script, basename($0) is certainly not
10765 enough.
10766 Pass the CLI arguments to `$as_me.lineno'.
10768 2001-09-25 Akim Demaille <akim@epita.fr>
10770 * lib/autotest/general.m4 (AT_INIT): Dump the whole config.log.

10778 of --language now.
10780 2001-09-23 Akim Demaille <akim@epita.fr>
10782 * doc/autoconf.texi (Top): Wrap in @ifnottex.
10784 2001-09-23 Akim Demaille <akim@epita.fr>
10786 * lib/autoconf/status.m4 (_AC_SRCPATHS): Compute and provide
10787 ac_buildpath, ac_top_buildpath, ac_srcpath, and ac_top_srcpath.
10788 (_AC_OUTPUT_FILES): Also substitute srcpath, top_srcpath,
10789 builddir, buildpath, top_builddir, and top_buildpath.
10790 (_AC_OUTPUT_SUBDIRS): Compute the dir variables *before* changing
10791 the current directory.
10792 * lib/autoconf/general.m4 (_AC_INIT_HELP): Compute the dir
10793 variables *before* changing the current directory.
10794 Skip nonexistent dirs.

10796 variables.
10798 * lib/autotest/general.m4: Do not reset AT_victims.
10799 Don't compute at_srcdir nor at_top_srcdir.
10801 * tests/tools.at: Hence use top_srcdir.
10803 * tests/Makefile.am, tests/autoconf, tests/autoheader,
10804 * tests/autom4te, tests/autoreconf, tests/autoupdate, tests/ifnames:
10805 Remove.
10806 * tests/autoreconf.in, tests/wrappl.in, tests/autom4te.in,
10807 * tests/wrapsh.in, tests/autoupdate.in: New.
10808 * tests/Makefile.am (DISTCLEANFILES, EXTRA_DIST): Adjust.
10809 * configure.ac: Build the position independent wrappers.
10811 * man/Makefile.am: Now that test wrappers are position
10812 independent, use them and drop dark envvar magic.
10814 2001-09-23 Akim Demaille <akim@epita.fr>
10816 * doc/autoconf.texi (Common Shell Constructs): Rename as...
10817 (Programming in M4sh): this.
10818 Promote to @section.

10822 * lib/autotest/general.m4 (AT_INIT): Dump config.log last.

10835 over-escaping.

10845 (Autoconf): Adjust.
10847 2001-09-23 Tim Van Holder <tim.van.holder@pandora.be>
10849 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/init.m4,

10860 * lib/autoconf/autotest.m4: Create `package.m4'.
10861 * tests/Makefile.am (package.m4): Remove.
10863 2001-09-22 Akim Demaille <akim@epita.fr>
10865 Rely on `$LINENO' when possible instead of `__oline__'.
10867 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Provide some form of
10868 `$LINENO' support replacement when not supported.
10869 (_AS_CR_PREPARE, _AS_TR_CPP_PREPARE, _AS_TR_SH_PREPARE): Invoke
10870 them explicitly to be sure they are not output before this section
10871 (via m4_require). Cosmetic only.
10872 * lib/autoconf/c.m4, lib/autoconf/general.m4,
10873 * lib/autoconf/programs.m4: Replace all the occurrences of
10874 `__oline__' with `$LINENO'.
10875 * doc/autoconf.texi (Special Shell Variables): Document LINENO.
10877 2001-09-21 Tim Van Holder <tim.van.holder@pandora.be>
10879 * lib/autoconf/functions.m4 (_AC_FUNC_FORK): Replaceded an 8-bit
10880 character (u: -> ue) in a code comment.
10881 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK): Only run 'ln -s' if we know
10882 it works.
10884 2001-09-21 Akim Demaille <akim@epita.fr>
10886 * Makefile.maint (AUTOM4TE): Neutralize autom4te.
10887 Suggested by Jim Meyering.
10889 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10891 * lib/autoconf/programs.m4: Use extensions listed in
10892 $ac_executable_extensions when looking for programs.
10894 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10896 * lib/autoconf/general.m4: Fix a small Englisho.
10897 * lib/autoconf/status.m4: Fix a small typo. Handle DOS paths when
10898 setting up ac_dir_suffix and ac_top_builddir.
10899 * lib/m4sugar/m4sh.m4: Default CDPATH to $PATH_SEPARATOR, not ':'.
10901 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>

10904 PATH_SEPARATOR.
10905 (Special Shell Variables[PATH_SEPARATOR]): Ditto.
10906 (Special Shell Variables[CDPATH]): Mention that $PATH_SEPRATOR should
10907 be used instead of ':'.
10908 * lib/autotest/general.m4: Replace occurrences of ':' in
10909 AUTOTEST_PATH with $PATH_SEPARATOR at test suite startup.
10911 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10913 * tests/atgeneral.m4: Add basic support for test ranges (e.g. 7-34) as
10914 arguments. Fixed a typo.
10916 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10918 * man/Makefile.am (.x.1): Use @PATH_SEPARATOR@, not ':' to set up
10919 $PATH. Also set AUTOM4TE_CFG, so we can process autom4te properly.
10921 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10923 * bin/autoscan.in: Add 'exec-perl-if-not-run-by-perl'.
10924 * bin/autoupdate.in: Ditto.
10925 * bin/autoheader.in: Reworded a few comments.
10926 * bin/autoconf.in: Reworded help text for a few options.
10927 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in,
10928 * bin/autoscan.in, bin/autoupdate.in: Ditto.
10930 2001-09-20 Tim Van Holder <tim.van.holder@pandora.be>
10932 * lib/Autom4te/XFile.pm (open): Simplified the error message (we
10933 already have $file). Set output files to binary mode (helps avoid
10934 CR issues on DOSish systems).
10936 2001-09-19 Akim Demaille <akim@epita.fr>
10938 * lib/autotest/general.m4: Englishoes.
10939 From Tim Van Holder and Alexey Mahotkin.
10941 2001-09-18 Paul Eggert <eggert@twinsun.com>
10943 * doc/autoconf.texi (Common Shell Constructs): New node,
10944 documenting AS_DIRNAME.
10945 (Limitations of Usual Tools): Refer to it when discussing dirname.
10946 Also, update discussion of POSIX standard to reflect latest draft.
10948 * lib/autoconf/c.m4:
10949 (AC_LANG_INT_SAVE(C)): Also support negative values, down to LONG_MIN.
10951 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10952 Do not pass a first argument with leading '-'
10953 to expr, by parenthesizing initial integers that might be negative.
10955 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10956 now merely checks whether it is an error to pass an argument
10957 to getpgrp.
10959 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
10960 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
10961 whether it is a (compile-time) error to pass an argument to
10962 getpgrp. This simpler test supports the revised documentation,
10963 and is all that AC_FUNC_GETPGRP's users really need.
10965 2001-09-18 Akim Demaille <akim@epita.fr>
10967 * doc/autoconf.texi (Limitations of Make) <$<>: New.
10969 2001-09-18 Akim Demaille <akim@epita.fr>

10975 2001-09-18 Paul Wagland <paul@wagland.net>
10977 * tests/m4sh.at: Ensure that AS_DIRNAME handles '/', '//' and '///'
10978 correctly.
10979 Add test for AS_BASENAME.
10980 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
10981 added test. It now correctly handles /1/2/3/, returning '3' not ''.
10982 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
10983 * tests/base.at: Fixed the expected responses. The old ones were
10984 one line out...
10985 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
10986 the documentation claims it should (and how it behaved in 2.13).
10988 2001-09-18 Akim Demaille <akim@epita.fr>
10990 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in
10991 the AC_CONFIG_COMMANDS invocation.
10992 This also solves the name clash problems.
10993 Don't set the package's ID.
10994 * lib/m4sugar/Makefile.am (version.m4): Revamp.
10995 No longer to be shipped.
10996 (version.in): Remove.
10997 * lib/m4sugar/m4sugar.m4, lib/autoconf/general.m4,
10998 * lib/autoconf/status.m4: Adjust.
10999 Use `m4_PACKAGE_STRING'.
11000 * lib/autotest/general.m4 (AT_INIT): N-th signature change: now
11001 the only optional argument is the name of the test suite.
11002 Expect `package.m4' to define the package signature.
11003 * lib/autom4te.in (Autotest): Add `package.m4?'.
11004 * tests/Makefile.am (package.m4): New.
11005 * tests/suite.at: ifnames is a victim.
11007 2001-09-18 Akim Demaille <akim@epita.fr>
11009 * lib/autom4te.in (Autoconf): Preselect AM_CONDITIONAL,
11010 AC_LIBSOURCE, AC_CONFIG_FILES.
11011 * lib/autotest/general.m4 (AT_INIT): Don't abort when a tested
11012 program version string doesn't match the package's.
11013 * lib/autoconf/general.m4 (AC_CACHE_VAL): Reestablish the space
11014 after `(cached)'.
11016 2001-09-17 Paul Eggert <eggert@twinsun.com>
11018 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11019 Allow expression to return any value that can fit into unsigned long
11020 (not int, as before). Check for output errors.
11022 2001-09-17 Bruno Haible <haible@ilog.fr>
11024 * lib/autoconf/c.m4: (AC_LANG_INT_SAVE(C)):
11025 Always include <stdio.h> and <stdlib.h>. Evaluate
11026 the expression in an extra function before these includes. Call
11027 fprintf "%d" only after ensuring the argument is of type 'int'.
11028 Reported by Wayne Chapeskie <waynec@spinnaker.com>.
11030 2001-09-17 Paul Eggert <eggert@twinsun.com>
11032 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11033 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11034 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11035 when they don't exist.
11037 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11038 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't
11039 need it.
11041 * lib/autoconf/specific.m4 (AC_ISC_POSIX): Replace the old, crufty
11042 version with the version used by fileutils 4.1, except use
11043 AC_SEARCH_LIBS, not AC_CHECK_LIB, so that we don't use -lcposix if
11044 we don't need it.
11046 * doc/autoconf.texi (AC_ISC_POSIX): Describe new behavior.
11048 2001-09-13 Akim Demaille <akim@epita.fr>
11050 * tests/base.at, tests/m4sh.at: Be sure to issue the bangshe line
11051 _first_.
11052 Reported by Gerrit P. Haase.
11054 2001-09-13 Akim Demaille <akim@epita.fr>
11056 * lib/autotest/general.m4 (AT_INIT): Reset `AT_victims' so that
11057 m4_defn'ing is valid.
11059 2001-09-13 Akim Demaille <akim@epita.fr>
11061 * lib/m4sugar/m4sugar.m4 (m4_append_uniq): New.
11062 * lib/autotest/general.m4 (AT_VICTIMS, AT_KEYWORDS, _AT_CLEANUP_FILE):
11063 Use it.
11065 2001-09-13 Akim Demaille <akim@epita.fr>
11067 * lib/m4sugar/m4sugar.m4 (_AS_QUOTE_IFELSE, _AS_BOX_INDIR): Use
11068 m4_match.
11069 (m4_re_escape): New.
11070 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER): Use it.
11071 * lib/autoconf/general.m4 (AC_CACHE_SAVE): Use m4_match.
11072 * lib/autoconf/status.m4 (AC_CONFIG_IF_MEMBER, AC_CONFIG_LINKS):
11073 Likewise.
11074 * lib/autoconf/types.m4 (_AC_CHECK_TYPE_REPLACEMENT_TYPE_P)
11075 (_AC_CHECK_TYPE_MAYBE_TYPE_P, AC_CHECK_MEMBER): Likewise.
11076 * lib/autotest/general.m4 (AT_INIT): Rename AT_TESTS_ALL as
11077 AT_tests_all for consistency.
11078 Set at_victims.
11079 (AT_VICTIMS): Similar to AT_KEYWORDS.
11080 (_AT_CLEANUP_FILE_IF): Use m4_match and m4_re_escape.
11082 2001-09-13 Akim Demaille <akim@epita.fr>
11084 * lib/autotest/general.m4 (AT_INIT): Fix stupid bugs.
11086 2001-09-13 Akim Demaille <akim@epita.fr>
11088 * lib/autotest/general.m4 (AT_INIT): Create and remove
11089 `$as_me.[0-9]+' instead of `debug-[0-9]+.sh', so that multiple
11090 test suites can cohabit.
11092 2001-09-13 Akim Demaille <akim@epita.fr>
11094 * tests/mktests.sh: Don't output banners for empty test files.
11096 2001-09-13 Akim Demaille <akim@epita.fr>
11098 Test suites can be run independently of configure.
11100 * lib/m4sugar/m4sh.m4 (_AS_ECHO, _AS_ECHO_N_PREPARE): New.
11101 * lib/autoconf/programs.m4 (_AC_PROG_ECHO): Remove.
11102 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust: AC_SUBST
11103 ECHO_N etc.

11106 * lib/autotest/general.m4: Use ECHO_*.
11108 2001-09-13 Akim Demaille <akim@epita.fr>
11110 * bin/ifnames.in: Rewrite in Perl.
11111 * configure.ac: Don't look for AWK.

11162 2001-09-07 Akim Demaille <akim@epita.fr>
11164 * bin/autom4te.in (&handle_m4): `< /dev/null' so that GNU M4 1.5
11165 doesn't neutralize SIGINT, making autoconf etc. non interruptible.
11166 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Move the package
11167 related variables into `at_package_*'.

11179 * lib/autotest/general.m4: Stop displaying srcdir everywhere as,

11200 2001-09-05 Akim Demaille <akim@epita.fr>
11202 Be ready to handle filenames as stupid as `dnl.at', for if even
11203 the maintainer is dumb enough to do that...
11205 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11206 excellence in M4 quotation: consider `__file__' is active.
11208 And BTW, when invoking m4, pass the --include in the right order:
11209 the wrong one.
11211 * bin/autom4te.in, bin/autoupdate.in: Use reverse when kingtal to
11212 4m.
11214 2001-09-05 Akim Demaille <akim@epita.fr>
11216 * lib/Autom4te/XFile.pm: New lib file.
11217 * bin/autoupdate.in, bin/autoscan.pl, bin/autom4te.in,
11218 * bin/autoheader.in: Use it.
11220 2001-09-05 Akim Demaille <akim@epita.fr>
11222 * bin/autoupdate.in (&handle_m4_macros) <unm4.m4>: Undefine iff

11234 2001-09-05 Akim Demaille <akim@epita.fr>
11236 CVS GNU M4 doesn't like `undefine(undefined)'.
11238 * bin/autoupdate.in (&handle_m4_macros, &handle_autoconf_macros):
11239 New, extracted from main.
11240 Use IO::File wherever possible.
11241 (input.m4): Be constant, use -I instead of hard coding $tmp.
11242 Therefore be a quoted heredoc.
11243 Don't invoke `_au_disable', since ac was not loaded, but just
11244 `unm4.m4'.
11246 2001-08-31 Akim Demaille <akim@epita.fr>
11248 Version 2.52d.
11250 2001-08-31 Akim Demaille <akim@epita.fr>

11253 previous patch.

11269 * lib/Makefile.am (CLEANFILES): Add autom4te.cfg.
11271 2001-08-31 Akim Demaille <akim@epita.fr>
11273 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11274 (testsuite Scripts): There is no such thing as `atconfig.in'.
11275 And actually one diagram is missing: test suite runtime.
11277 2001-08-31 Akim Demaille <akim@epita.fr>
11279 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11280 inverse order.
11282 2001-08-31 Akim Demaille <akim@epita.fr>
11284 * bin/autoupdate.in (@include): `installcheck' revealed the path
11285 to m4sugar was lacking!
11287 2001-08-31 Akim Demaille <akim@epita.fr>
11289 * man/Makefile.am (.x.1): We really have to pass
11290 autom4te_perllibdir.
11292 2001-08-31 Akim Demaille <akim@epita.fr>
11294 * lib/autotest/general.m4 (AT_INIT): Don't pass all the args to
11295 debug scripts, in particular passing explicitly listed tests to
11296 run is stupid.
11298 2001-08-31 Akim Demaille <akim@epita.fr>
11300 * bin/autom4te.in (&parse_args): Strip `.' from `@include'.
11301 * bin/autoupdate.in: Use --include, -I, and --force, -f, too.
11302 Use directly autom4te, not autoconf.
11303 * tests/autoupdate: $top_srcdir/lib is needed too for melt files.
11305 2001-08-31 Akim Demaille <akim@epita.fr>
11307 * tests/semantics.at (AC_C_BIGENDIAN): Missing eol.
11308 * bin/autoheader.in (%symbol): Strip arguments of macros.

11316 * bin/autom4te.in (&parse_args): Die on unknown languages.
11317 * bin/autoheader.in: Run directly autom4te --mode=autoconf, no
11318 need for autoconf.
11319 Promote --include over --macrodir and other obsolete options.
11321 2001-08-31 Akim Demaille <akim@epita.fr>
11323 * lib/Autom4te/General.pm ($version, $help, &getopt): New.

11325 * bin/autom4te.in ($autoconf): Pass --force.
11326 `print $out' doesn't print `$_' but `$out'.
11327 * tests/tools.at (Syntax of the Perl scripts): Pass the lib dir.
11328 (autoheader): Pass --force since the test suite goes too fast for
11329 the time stamps.
11330 Adjust to the new autoheader messages.
11332 2001-08-31 Akim Demaille <akim@epita.fr>
11334 * bin/autoheader.in: Handle the acconfig.h etc. junk files.
11335 Check the completeness of the #template.
11336 * lib/Autom4te/General.pm (&update_file): s/remove/unlink/.
11337 * tests/semantics.at (AC_C_BIGENDIAN): Adjust AT_CHECK_AUTOHEADER

11343 * bin/autoupdate.in, bin/autoheader.in: Adjust.
11344 Drop AC_MACRODIR dead for real.
11345 * tests/atspecific.m4 (AT_CHECK_AUTOHEADER): Now autoheader says
11346 `autoheader: `config.hin' is created'.
11347 * tests/tools.at (Syntax of the Perl scripts): Check autoheader.
11349 2001-08-31 Akim Demaille <akim@epita.fr>
11351 * bin/autoheader.in: Rewrite in Perl.
11352 * tests/autoheader: Adjust.
11354 2001-08-31 Akim Demaille <akim@epita.fr>
11356 * bin/autoconf.in (--include, -I): New option.
11357 Map --localdir, --autoconf-dir onto it.
11358 Forward autom4te's options instead of interpreting them.
11359 * bin/autoconf.in, bin/autoheader.in (AC_MACRODIR, autoconf_dir):
11360 There is no such envvar since the inception of autom4te.cfg.
11361 * bin/autom4te.in (&parse_args): Uniquify `@include'.
11362 * bin/autoupdate.in: Adjust, and perform more control.
11363 * tests/atspecific.m4 (AT_CHECK_AUTOCONF): Adjust.
11364 * tests/autoconf: Dittowise.
11366 2001-08-31 Akim Demaille <akim@epita.fr>
11368 * bin/autoconf.in: Don't bother with `acsite.m4' and `aclocal.m4'.
11369 * bin/autom4te.in (&find_file): Support `FILE?' standing for
11370 optionally `FILE'.
11371 Use -e, not -f, since /dev/null for instance is OK.
11372 (&parse_args): Adjust.
11373 * lib/autom4te.in (Autoconf): Add `acsite.m4?' and `aclocal.m4?'.
11375 2001-08-31 Akim Demaille <akim@epita.fr>
11377 * configure.ac: Also find tested executables in bin.
11378 * bin/autoconf.in, bin/autoheader.in, bin/autoreconf.in,
11379 * bin/autoscan.in, autoupdate.in: Use exclusively the name of the
11380 installed peer executables, only PATH is allowed to resolve it.
11381 Pass `autoconf_dir' via options, not via invisible envvars.
11382 * lib/Autom4te/General.pm (&find_peer): Remove.
11383 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives
11384 `abuild:asrc:bbuild:bsrc', not `abuild:bbuild:asrc:bsrc'.
11385 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11386 find the executables for it.
11387 * tests/Makefile.am: Major cleanup. Too lazy to document...
11388 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11389 We only need PERL.
11390 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11391 indeed related to running the test suite, while passing
11392 --autoconf-dir and others is related to running non installed
11393 Autoconf executables. So don't do that, leave it to...
11394 * tests/autoconf, tests/autoheader, tests/autom4te, tests/autoupdate,
11395 * tests/autoscan: New.
11396 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't
11397 refer to library files: rely on --language.
11399 2001-08-29 Akim Demaille <akim@epita.fr>
11401 * bin/autom4te.in, lib/autom4te.in, bin/autoconf.in:
11402 s/--set/--language/.
11404 2001-08-29 Akim Demaille <akim@epita.fr>
11406 * doc/autoconf.texi: Strip the @nodes.
11407 Suggested by Paul Eggert.

11410 2001-08-29 Akim Demaille <akim@epita.fr>
11412 * bin/autom4te.in (&handle_output): s/@__@/@&t@/.
11413 Suggested by Paul Eggert.
11415 2001-08-29 Akim Demaille <akim@epita.fr>
11417 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11418 download in a tmp dir.
11420 2001-08-29 Akim Demaille <akim@epita.fr>
11422 * lib/autotest/general.m4: s/AT-devnull/devnull/ since there are

11433 (&parse_args): Support --mode, --set, and --melt.
11434 * bin/autoconf.in: Simplify and adjust.
11435 * tests/Makefile.am (AUTOMAKE): Use --set.
11436 * tests/atlocal.in: Adjust.
11437 * BUGS: distcheck and check are weak.
11439 2001-08-29 Akim Demaille <akim@epita.fr>
11441 * lib/autotest/general.m4: Use
11442 foo=`(command) 2>/dev/null`
11443 not
11444 foo=`command` 2>/dev/null
11445 (at-devnull): Rename as...
11446 (AT-devnull): this.
11447 (--clean): Remove AT-* files too.
11448 * doc/autoconf.texi (Limitations of Usual Tools): Document `date'.
11449 Reported by Nicolas Joly.

11459 * doc/autoconf.texi (Function Portability): Mention C right shifts.

11465 Support test ranges as arguments to the testsuite.
11466 Have -e imply -d as the help text suggested.
11468 2001-08-27 Akim Demaille <akim@epita.fr>
11470 * Makefile.maint: Formatting changes.
11471 (do-po-update, po-update, cvs-update, update): New targets.

11483 * lib/autotest/general.m4 (AT_INIT): Log the command line.
11484 Support `VAR=VAL' as arguments.

11504 * lib/autoconf/status.m4 (_AC_SRCPATHS): Rename `ac_dots' as
11505 `ac_top_builddir' to mimic Automake's vocabulary, which much more
11506 readable.
11507 Adjust callers.
11508 * doc/autoconf.texi (Configuration Actions): Document the vars
11509 available in commands.
11510 Emphasize the risks of collisions in init-cmds.

11573 (AMTAR): Help automake define it.
11574 (INSTALL, install-data-hook): The INSTALL.txt trick is no longer
11575 needed, 1.5 can have a macro and a target with the same name.
11576 * m4/auxdir.m4, m4/cond.m4, m4/depend.m4, m4/install-sh.m4,
11577 * m4/strip.m4: New.

11593 the name of the directory they're in, instead of the filename,
11594 since version.m4 is now in m4sugar, but m4_acversion must not be
11595 classified as an Autoconf macro.
11596 ($input_m4): Don't qualify the path to m4sugar.
11597 Rather, pass autoconf_dir to m4.
11598 * tests/Makefile.am (testsuite): Remove -I top_srcdir, unneeded.

11686 2001-08-20 Akim Demaille <akim@epita.fr>
11688 Info readers seem to need `Index' in the index node title :(

11740 * lib/autoconf/general.m4, lib/autoconf/specific.m4,
11741 * lib/autotest/general.m4: Rename the EOF tags as `_ACEOF',

11804 * lib/autotest/general.m4 (AT_INIT): Refer to `$as_me.log', not

11822 * doc/autoconf.texi: Work around Texinfo buglets.
11823 (Transformation Rules): One example is enough, users are expected
11824 to have their brains on. And BTW, use DESTDIR.
11825 (dvar): New macro. Use it.
11827 2001-08-17 Akim Demaille <akim@epita.fr>
11829 * doc/autoconf.texi (Writing testsuite.at) <AT_CHECK>: Complete.

11877 (cvs-dist): depends upon it.
11879 2001-08-15 Tim Van Holder <tim.van.holder@pandora.be>
11881 * tests/Makefile.am: Use a clean-local rule to remove
11882 autom4te.cache (it's a directory, not a file.
11883 * Makefile.am: Ditto (but maintainer-clean-local).
11885 2001-08-15 Akim Demaille <akim@epita.fr>
11887 * bin/autom4te.in (@m4_warning): New.
11888 (&handle_m4): Use it.
11889 * tests/m4sugar.at (m4_warn): Pass `-f' to autom4te to ensure the

11953 * tests/mktests.sh: Update year in copyright notice.
11955 2001-08-12 Alexandre Duret-Lutz <duret_g@epita.fr>
11957 * tests/semantics.at (AC_C_BIGENDIAN): New test.
11959 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11961 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
11962 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
11963 * doc/autoconf.texi (C Compiler Characteristics): Update
11964 documentation for AC_C_BIGENDIAN.
11966 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
11968 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
11969 magic values from an object file when cross-compiling.
11970 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
11972 2001-08-10 Akim Demaille <akim@epita.fr>
11974 * bin/autom4te.in (&handle_output): Don't use `grep' with side
11975 effects.
11976 Suggested by Russ Allbery.
11978 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
11980 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
11981 current $prefix to the sub-configures.
11983 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
11985 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable

11992 2001-08-07 Akim Demaille <akim@epita.fr>
11994 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
11995 removed.
11996 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
11997 No need to remove the files before and after the each test, before
11998 each test and at the end of the suite is enough.
11999 Display only the children `times', not the shell's.
12000 If the test failed or was skipped, at-times is not available.
12002 2001-08-07 Akim Demaille <akim@epita.fr>
12004 Always produce testsuite.log, including when there are no
12005 failures. This helps getting information on skipped tests, and
12006 duration of the tests. Err, implement the latter btw.
12008 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12009 Dump information on the first run of each test.
12010 (AT_CLEANUP): Create `at-times' containing the duration of the
12011 test group.
12013 2001-08-07 Akim Demaille <akim@epita.fr>
12015 The use of `dumpstat' revealed that `len' was used although it
12016 should not. m4_text_wrap was using it, but in the Autoconf world
12017 where it is legal. Hence (i) test M4sh in its own world, not
12018 Autoconf's, and (ii), ahem, fix the bug :)
12020 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12021 does not like `' instead of [].
12022 (AT_INIT): Forbid `^_?AT_'.
12023 And don't output such tokens.
12024 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12025 `script.as', and `autom4te.cache'.
12026 Remove `empty' and `macro' which are no longer used.

12028 * tests/m4sugar.at: Use it.

12042 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12043 AC_TRY_LINK.

12048 2001-08-04 Akim Demaille <akim@epita.fr>
12050 Don't rely on M4sugar outputting the patterns in files, since we
12051 might process the output _without_ running m4, hence without these
12052 files.
12054 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12055 * bin/autom4te.in (@Request::includes): Remove, unused.

12057 (@Request::input): this.

12059 (&handle_output): Fetch the patterns from the traces.

12062 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12064 2001-08-04 Akim Demaille <akim@epita.fr>
12066 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12067 autoconf', i.e., in addition to caching traces, cache the output.

12085 2001-08-04 Akim Demaille <akim@epita.fr>
12087 Don't let autom4te compute the `include' traces several times:
12088 first check that the trace cache file is up to date, and then
12089 compare its timestamp with that of the output.
12091 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12092 the preamble. Don't require 5.005 as Autom4te::General does it,
12093 and better yet (use `use', not `require'!).
12094 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12095 Class::Struct as Autom4te::Struct.
12096 * lib/Autom4te/General.pm (File::stat): Use it.
12097 (&mtime): New, export it.
12098 * bin/autom4te.in: Use it.

12116 macros invoked without arguments, and macros invoked with multiple
12117 lines arguments.
12119 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12121 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12122 arguments.
12124 2001-08-03 Akim Demaille <akim@epita.fr>
12126 * bin/autoconf.in ($@): Work around the usual sh bug.

12151 mismatch happens.
12152 * bin/autom4te.in (&handle_output): Remember of the first
12153 occurrence of a possibly undefined macro, not the last.

12155 the appear in the output.

12164 * configure.ac: Bump to 2.52c.

12616 provide an alternate 'main' function name, using the 'main' from
12617 the Fortran libraries.
12618 (AC_LANG_PROGRAM(C)): Use F77_DUMMY_MAIN, if it is defined, so that
12619 cross-language link tests can be performed successfully.
12620 (_AC_F77_NAME_MANGLING): Require AC_F77_DUMMY_MAIN. Also put $FLIBS
12621 after $LIBS, for consistency; this should be the general rule since
