13 2007-02-06 Ralf Menzel <menzel@ls6.cs.uni-dortmund.de> (tiny change)
15 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Redirect
16 input from /dev/null in awk test, so even Solaris /usr/bin/awk
17 will not wait for input with a script containing only a BEGIN

26 2007-02-02 Eric Blake <ebb9@byu.net>
28 * NEWS: Update copyright.
30 * m4/m4.m4 (AC_PROG_GNU_M4): Reject M4 1.4 through 1.4.4 as

51 2007-01-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
53 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Also
54 AC_SUBST([MKDIR_P]), so that Automake < 1.10 will pick up its
55 trace, if a package uses AC_PROG_MKDIR_P explicitly. The actual
56 substitution will still be done by the special code.
57 Report by Jim Meyering.
59 * doc/autoconf.texi (File System Conventions): Mention that
60 $PATH_SEPARATOR is for the build system only.
61 Report by Keith Marshall.
63 2007-01-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
65 * doc/autoconf.texi (Setting Output Variables): Mention that
66 all non-NUL characters are ok in substituted values.
67 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Fix comment typo.
68 (_AC_OUTPUT_FILES_PREPARE): Test and use backslash escaping of
69 carriage return for $AWK, needed for BSD awk.
70 * tests/torture.at (Substitute and define special characters):
71 Test all 8 bit non-NUL characters.
72 Report against Automake by Patrick Welche.
74 2007-01-15 Stepan Kasal <kasal@ucw.cz>

77 change the build type.
79 2007-01-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
81 * lib/autoconf/programs.m4 (AC_PROG_SED): When closing a pipe
82 early on the reader side, drop stderr of the input to avoid
83 `broken pipe' error output; this may happen even with shell
84 builtin `echo' of some bash versions. Reports by Ian Macdonald
85 <iamacdo@telkomsa.net> and Sam Sexton <Sam.Sexton@reuters.com>.
87 2007-01-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
89 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Use newlines to
90 separate items of `ac_user_opts', to avoid long lines.
91 (_AC_INIT_PARSE_ENABLE2, _AC_ENABLE_IF_ACTION): Adjust.
93 2007-01-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
95 * doc/autoconf.texi: Fix some typos.
97 2007-01-05 Paul Eggert <eggert@cs.ucla.edu>
99 Fix some wording problems noted by Paolo Bonzini in:
100 http://lists.gnu.org/archive/html/autoconf-patches/2007-01/msg00077.html
101 * doc/autoconf.texi (Signed Overflow Examples): Give more
102 discussion about the allow_superuser_privileges example,
103 and change it a bit to make things clearer.
104 (Optimization and Wraparound): Clarify whether the compiler
105 will generate an infinite loop for the example derived from
106 Autoconf's mktime test.
107 (Signed Overflow Advice): Say that -ftrapv is meant for debugging.
108 Also, clarify unsigned multiplication overflow.
110 2007-01-04 Eric Blake <ebb9@byu.net>
112 * bin/Makefile.am (RELEASE_YEAR): New macro.
113 (edit): Use it to supply correct copyright year to scripts.
114 * bin/autoconf.as (version): Use it.
115 * bin/autoheader.in ($version): Likewise.
116 * bin/autom4te.in ($version): Likewise.
117 * bin/autoreconf.in ($version): Likewise.
118 * bin/autoscan.in ($version): Likewise.
119 * bin/autoupdate.in ($version): Likewise.
120 * bin/ifnames.in ($version): Likewise.
122 2007-01-02 Paul Eggert <eggert@cs.ucla.edu>
124 * doc/autoconf.texi (Integer Overflow): Revised based on today's
125 feedback. The most important changes document what happens when
126 you convert an out-of-range value to a signed integer type, and
127 say that (sum < a) != (b < 0) reliably detects overflow when sum =
130 * doc/autoconf.texi (Integer Overflow): Greatly expand and
131 rewrite, taking notions from the recent discussion on the gcc and
132 autoconf mailing lists; please see
133 http://lists.gnu.org/archive/html/autoconf-patches/2006-12/msg00091.html
134 and follow the many links.
135 (Integer Overflow Basics, Signed Overflow Examples):
136 (Optimization and Wraparound, Signed Overflow Advice):
137 (Signed Integer Division): New sections.
139 2006-12-28 Steven G. Johnson <stevenj@alum.mit.edu>
141 * lib/autoconf/general.m4 (AC_DEFINE_TRACE): Don't include
142 preprocessor macro arguments in traced name.
143 * doc/autoconf.texi (Defining symbols): Document longstanding
144 support for AC_DEFINE-ing macros with arguments, and document
145 behavior when the same variable has multiple AC_DEFINEs.
146 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Revert to the
147 old implementation which AC_DEFINEs the FC_FUNC and FC_FUNC_
148 macros directly, giving much shorter and simpler code.
150 2006-12-28 Malcolm Purvis <malcolmp@xemacs.org> (trivial change)
152 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Insert a
153 space before "$ac_configure_args" to prevent a 'config.status
154 --recheck' failure if ac_configure_args doesn't contain a leading
155 space. This works around a problem with the XEmacs configure.ac,
156 which uses the (undocumented) ac_configure_args variable
157 inconsistently with Autoconf.
159 2006-12-22 Paul Eggert <eggert@cs.ucla.edu>
161 * lib/autoconf/functions.m4 (AC_FUNC_MKTIME):
162 Include <limits.h>, and use its INT_MAX to rewrite the
163 j loop so that it does not overflow 'int'. Problem reported by
165 <http://lists.gnu.org/archive/html/bug-gnulib/2006-12/msg00084.html>.
166 Play it safe by shifting left by 1 rather than multiplying by 2,
167 as GCC is less likely to optimize this away when the value
168 is signed (when it assumes overflow leads to undefined behavior).
169 Also, don't assume time_t uses two's complement.
171 2006-12-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
173 * tests/torture.at (Substitute a 2000-byte string): Avoid using
174 a 10kB long (multi-line) string literal, OpenServer 5.0.7 ksh
175 dumps core on it. Report by Tim Rice.
177 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
179 * lib/autoconf/general.m4 (AC_ARG_ENABLE): Print help about
180 --disable-option-checking to --help output even when
181 AC_PRESERVE_HELP_ORDER is not used.
182 (_AC_INIT_PARSE_ENABLE2): Print warnings using actual --enable or
183 --with argument, rather than argument with [-.] replaced by
185 * NEWS: Fix typo in previous change; the news was in the
188 2006-12-18 Paul Eggert <eggert@cs.ucla.edu>
190 * NEWS: Warnings are now generated by default for unknown
191 --enable-* and --with-* options.
192 * doc/autoconf.texi (Option Checking): Renamed from
193 (Configure Option Checking). Tighten up the wording a bit.
194 (External Software, Package Options): Cross-reference to Option
195 Checking, and use this to shorten our section.
196 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Prefer test -n
197 "$x" to test "x$foo" != x.
198 * lib/autoconf/status.m4 (AC_OUTPUT): Likewise.
199 Don't warn if $enable_option_checking is "no".
200 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Initialize
201 ac_unrecognized_opts to the empty string.
202 Don't echo the unrecognized opts, as this might mishandle
203 backslashes or leading -.
204 (AC_PRESERVE_HELP_ORDER): Put the --disable-option-checking
205 usage next to the other --disable-FEATURE options in the
208 2006-12-18 Steven G. Johnson <stevenj@alum.mit.edu>
210 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS, _AC_INIT_PARSE_ARGS):
211 (_AC_INIT_PARSE_ENABLE2, _AC_INIT_HELP, _AC_ENABLE_IF):
212 Print warning for unrecognized --with and --enable options
213 (AC_DISABLE_OPTION_CHECKING): New macro to disable warnings.
214 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS, _AC_OUTPUT_SUBDIRS):
215 Disable option checking when subdirs are configured.
216 (AC_OUTPUT): If warnings are enabled, print warning about
217 unrecognized --with and --enable options at the end of
218 the configure output (as well as at the beginning).
219 * doc/autoconf.texi (Option Checking): New node.
220 Document new option warning functionality.
222 2006-12-16 Eric Blake <ebb9@byu.net>
224 * configure.ac (AC_INIT): Bump version, since 2.61a is released.
225 * NEWS: Start news for current version.
227 2006-12-15 Paul Eggert <eggert@cs.ucla.edu>
229 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
230 Define HAVE_GETMNTENT to 1, not to the empty string.
231 Problem originally reported by Jochen Friedrich in
232 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=403243>.
234 This change prompted by a problem report by Andrey Simonenko in
235 <http://lists.gnu.org/archive/html/bug-autoconf/2006-12/msg00026.html>.
236 * doc/autoconf.texi (Defining Symbols): AC_DEFINE works for
237 object-like macros only, in the traditional portable character
239 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL):
240 Warn about attempts to define things that are not identifiers.
241 * lib/autoconf/fortran.m4 (_AC_FC_WRAPPERS): Rewrite to avoid
242 awful hack that AC_DEFINEd macro names containing parentheses.
244 2006-12-12 Paul Eggert <eggert@cs.ucla.edu>
246 * doc/autoconf.texi: Undo some of the 2006-12-10 change. It was
247 too drastic, even if Texinfo in theory requires it for info mode.
249 (config.status Invocation): Renamed back from Recreating a
251 (Obsolete config.status Use): Renamed back from Obsolete Recreation.
252 (Autoconf 2.13): Renamed back from 20th-century Autoconf 2.
254 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
256 * NEWS: Version 2.61a.
258 2006-12-11 Paul Eggert <eggert@cs.ucla.edu>
259 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
261 * NEWS: Document changes with echo and printf, and the lack
262 of limits on the total size of multi-line values of substituted
263 variables, and the AC_FUNC_FSEEKO fix.
265 2006-12-10 Paul Eggert <eggert@cs.ucla.edu>
267 * doc/autoconf.texi (Writing Autoconf Input): Renamed from
268 Writing configure.ac.
269 (Autoconf Input Layout): Renamed from configure.ac Layout.
270 (Recreating a Configuration): Renamed from config.status Invocation.
271 (Obsolete Recreation): Renamed from Obsolete config.status Use.
272 (acconfig Header): Renamed from acconfig.h.
273 (20th-century Autoconf 2): Renamed from Autoconf 2.13.
274 (Writing Testsuites): Renamed from Writing testsuite.at.
275 (Autom4te Cache): Renamed from autom4te.cache.
277 * BUGS: Remove mention of VPATH problem, since it's now documented
278 not to be a bug in the Autoconf build procedure itself, but rather
279 a problem with the proprietary `make' programs.
281 * doc/autoconf.texi (Build Directories): Add a cross reference
284 * build-aux/config.guess, build-aux/config.sub, build-aux/texinfo.tex:
285 * doc/standards.texi: Sync from gnulib.
287 * man/autoconf.1, man/autoheader.1, man/autom4te.1, man/autoreconf.1:
288 * man/autoscan.1, man/autoupdate.1, man/config.guess.1:
289 * man/config.sub.1, man/ifnames.1: Remove from CVS, since they're
290 generated automatically.
292 2006-12-06 Paul Eggert <eggert@cs.ucla.edu>
294 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Also try -xc99=all, for Sun
295 C 5.8 on Solaris 10. Using -xc99=all rather than -xc99 bypasses
296 the buggy -xc99 option of Forte Developer 7 C on Solaris 9.
298 2006-12-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
300 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Drop the
301 `CEOF$ac_eof' special marker, the awk script cannot contain a
302 line matching `^CEOF', so this is not needed any more.
303 * tests/torture.at (Substitute a newline): Expose the `%!_!# '
304 special marker in the test.
306 2006-12-06 Stepan Kasal <kasal@ucw.cz>
308 * tests/tools.at (autom4te preselections): Use `find -newer';
309 remove one of the sleeps.
311 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Make it
312 more readable, using ...
313 (_AC_INIT_PARSE_ENABLE2): ... this new helper macro.
315 * doc/autoconf.texi (autoheader Invocation): Do not double-
316 quote the parameter of `AH_BOTTOM' in the example.
318 2006-12-05 Stepan Kasal <kasal@ucw.cz>
320 * doc/autoconf.texi (Configuration Headers): Remove the
321 example with multiple input files.
322 (autoheader Invocation): Encourage `AH_BOTTOM', discouraging
323 multiple input files.
325 2006-12-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
327 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): When
328 creating the awk substitution script, handle one input line at a
329 time, so that the maximum length of a substituted (multi-line)
330 value is not limited by the size of the sed pattern space.
331 The trade-off is a slightly repetitive sed script.
332 * doc/autoconf.texi (Limitations of Usual Tools): Branch labels
333 can only have up to 7 characters, due to Solaris 10 /bin/sed.
334 * tests/torture.at (Substitute a 2000-byte string): Increase the
335 test with several long lines, they should not be caught by sed
338 * tests/tools.at (autom4te preselections): New test, to flag
339 entries missing from autom4te.cfg.
340 Report by David Byron <dbyron@hheld.com>.
342 * tests/torture.at (Substitute a 2000-byte string): Actually use
343 AC_PROG_AWK, so the last change works as intended.
344 (Substitute and define special characters): Likewise.
345 (Substitute a newline): Likewise.
347 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Use `$AWK'
348 instead of `awk' consistently.
349 (_AC_OUTPUT_CONFIG_STATUS): Initialize $AWK.
350 * tests/torture.at (Torturing config.status): Test both the
351 result of AC_PROG_AWK and plain awk.
352 (Substitute a 2000-byte string): Likewise.
353 (Substitute and define special characters): Likewise.
354 (Substitute a newline): Likewise.
356 2006-12-04 Paul Eggert <eggert@cs.ucla.edu>
358 * lib/autoconf/functions.m4 (AC_FUNC_FSEEKO): Check that fseeko
359 can be assigned to a function pointer. Problem reported by
360 Peter Palfrader in <http://bugs.debian.org/401377>. Based on
361 part of a patch by Ralf Wildenhues in that same bug report.
363 2006-12-01 Paul Eggert <eggert@cs.ucla.edu>
365 * tests/mktests.sh (ac_exclude_list): Exclude AC_FUNC_SETVBUF_REVERSED.
366 * tests/semantics.at (AC_FUNC_SETVBUF_REVERSED): New test.
368 2006-12-01 Eric Blake <ebb9@byu.net>
370 * lib/autoconf/c.m4 (AC_LANG_INT_SAVE): Avoid newline, to aid in
371 cross-compiling from cygwin to mingw.
372 Reported by Bob Rossi. This resurrects the 2000-11-30 patch to
373 aclang.m4, which was mistakenly removed in the 2001-09-17 patch
374 to lib/autoconf/c.m4.
376 2006-12-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
378 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Use a longer test
379 string for more reliable failure. Wrap the entire test that
380 causes the broken Solaris printf to dump core, in a subshell,
381 so the segmentation fault message is reliably suppressed.
382 Fix shell expansion errors by using /usr/ucb/echo always;
383 avoid an error on systems without it by another subshell.
384 Avoid m4 expansion of `$1'. Set the zeroth argument of the
385 subshell-$as_echo to `as_echo', for better error message.
387 2006-11-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
389 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): If `BASH_ARGV' or
390 `BASH_SOURCE' contain a newline, set them to empty, as they may
393 2006-11-27 Paul Eggert <eggert@cs.ucla.edu>
395 Turn AC_FUNC_SETVBUF_REVERSED into a noop. It's been obsolete for
396 years and is too hard to maintain now. The last straw was
397 reported by Jerker Baeck in
398 <http://lists.gnu.org/archive/html/autoconf/2006-11/msg00102.html>.
399 * NEWS: AC_FUNC_SETVBUF_REVERSED is now obsolete.
400 * doc/autoconf.texi (Particular Functions): Move
401 AC_FUNC_SETVBUF_REVERSED from here...
402 (Obsolete Macros): ... to here. Say that it does nothing now.
403 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
404 Turn into (almost) a no-op.
406 * lib/autoconf/c.m4 (AC_PROG_GCC_TRADITIONAL, AC_C_CONST):
408 Do not recommend via AN_FUNCTION, AN_IDENTIFIER, or AN_HEADER.
409 These macros are obsolescent and new applications shouldn't need them.
410 * lib/autoconf/functions.m4 (AC_FUNC_CLOSEDIR_VOID, AC_REPLACE_FNMATCH):
411 (AC_FUNC_GETLOADAVG, AC_FUNC_GETPGRP, AC_FUNC_MEMCMP):
412 (AC_FUNC_SELECT_ARGTYPES, AC_FUNC_SETPGRP, AC_FUNC_STAT, AC_FUNC_LSTAT):

417 * lib/autoconf/types.m4 (AC_STRUCT_TM): Likewise.
419 * doc/autoconf.texi (Setting Output Variables): Mention that
420 @VAR1@VAR2 has unspecified behavior. Problem reported by
422 * NEWS: Mention this.
424 * Makefile.am: Put only a single '#' into the copyright notice,
425 so that it's also present in the output file. Standardize wording
426 in makefile copyright notices to match GNU coding standards.
427 * bin/Makefile.am: Likewise.

440 2006-11-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
442 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE): Fix error
443 in the sed script that mangles the awk script: delete up to the
444 first exclamation mark only.
445 * tests/torture.at (Substitute and define special characters):
448 2006-11-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
450 Rewrite config files generation: avoid quadratic growth in
451 the number of substituted variables by using awk instead of sed
452 for the bulk of the substitutions.
453 * NEWS: Mention this.
454 * doc/autoconf.texi (Setting Output Variables): `|#_!!_#|' is also
455 forbidden in the output (and thus input) file.
456 * lib/autoconf/status.m4 (_AC_AWK_LITERAL_LIMIT): New macro.
457 (_AC_OUTPUT_FILES_PREPARE): Instead of several sed scripts,
458 generate just one large awk script for substitutions,
459 eliminating much of the earlier complexity, while adding some
460 new complexity. Only expand the substitution templates at
461 configure time, for smaller configure script size. If
462 _AC_SUBST_FILES are used, test 'awk' for working getline support
463 at config.status time. If absent, interpolate through the
464 shell. The awk script was written with much help
465 from Paolo Bonzini and Paul Eggert.
466 (_AC_SED_CMD_NUM, _AC_SED_DELIM_NUM, _AC_SED_FRAG): Removed.
467 (_AC_SED_FRAG_NUM): Likewise.
468 (_AC_SUBST_CMDS): Renamed from...
469 (_AC_SED_CMDS): ...this.
470 (_AC_OUTPUT_FILE): Use _AC_SUBST_CMDS.
471 * tests/torture.at (Substitute a 2000-byte string): Also
472 substitute a line with 1000 words, and a variable with several
474 (Substitute and define special characters): Test awk special
475 characters, and put substitution input strings `@foo@' in the
476 output, to test that no recursion happens; test several other
477 combinations from Paolo Bonzini.
479 2006-11-25 Paul Eggert <eggert@cs.ucla.edu>
481 * lib/autotest/general.m4 (AT_INIT): Undo recent changes
482 that replaced echo with AS_ECHO where this wasn't necessary.
483 Problem reportd by Ralf Wildenhues.
484 * lib/m4sugar/m4sh.m4 (_AS_ECHO_PREPARE): Port to Solaris 7,
485 where "/usr/bin/printf '%s\n' S" dumps core if S is long.
486 This is Sun bug 4206210. Problem reportd by Ralf Wildenhues.

490 * lib/freeze.mk (GREP): Removed, no need to initialize this.
492 2006-11-21 Paul Eggert <eggert@cs.ucla.edu>
494 * doc/autoconf.texi (Limitations of Usual Tools): Don't claim
495 that traditional Awk lacks 3-arg "split". It has it.
496 Mention that FS must be a single character, and a few other
497 99-byte limits of traditional Awk.
498 Mention that if (i in a) doesn't work with traditional Awk.
500 2006-11-18 Paul Eggert <eggert@cs.ucla.edu>
502 * tests/autotest.at (BSx641-newline in command):
503 (BS-BS-newline in command, BSx640-newline in command):
504 (Newline-CODE-BS-newline in command):
505 (Single-quote-BS-newline in command):
506 (Single-quote-newline-BS-newline in command):
507 Use printf '%s\n' instead of echo, for portability to hosts
508 where echo interprets backslashes. This will break on hosts
509 that lack printf, but for now let's assume all such hosts
510 are dead (if not, we should get reports of test failures).
512 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
514 'echo' has some portability problems, when given a first argument
515 with a leading '-', or when given any argument containing '\'.
516 Avoid using 'echo' in these cases.
517 * bin/Makefile.am $(bin_SCRIPTS): Rewrite to avoid 'echo' entirely.
518 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Likewise.
519 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
520 * lib/autotest/general.m4 (AT_INIT): Likewise.
521 * bin/autoconf.as: Use AS_ECHO rather than plain echo, when the
522 argument might be unportable.
523 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Likewise.
524 * lib/autoconf/erlang.m4 (AC_LANG(Erlang)): Likewise.
525 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT):
526 (_AC_FC_LIBRARY_LDFLAGS): Likewise.

536 (_AC_OUTPUT_SUBDIRS, _AC_OUTPUT_CONFIG_STATUS): Likewise.
537 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT, AT_INIT):
538 (AT_CLEANUP, _AT_DECIDE_TRACEABLE, _AT_CHECK): Likewise.
539 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE, _AS_ECHO_UNQUOTED):

541 (AS_TR_SH, AS_TR_CPP, AS_VAR_GET): Likewise.
542 * bin/autoconf.as: Redo verbose flag implementation, as the old
543 scheme wouldn't work with AS_ECHO.
544 * lib/autotest/general.m4 (AT_INIT): Likewise.
545 * lib/autoconf/general.m4 (AC_MSG_RESULT, AC_MSG_RESULT_UNQUOTED):
546 Don't use ECHO_T, since ECHO_N is now reliable.
547 * lib/autotest/general.m4 (AT_INIT): Likewise.
548 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Use sed "$script"
549 rather than using a here-document to put the script into a file.
550 (_AC_DO_ECHO): Hoist the eval out of the echo, so that we can
552 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Likewise.
553 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Use
554 AS_ECHO_N rather than ECHO_N and ECHO_C. This doesn't fix any
555 bug, but we might as well stop using ECHO_N and ECHO_C internally.
556 * lib/autotest/general.m4 (AT_SETUP): Likewise.
557 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N): Likewise.
558 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
559 (_AC_OUTPUT_MAIN_LOOP): Rework echo so that it has just one
560 operand, as AS_ECHO requires. Avoid double file name expansion.
561 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Invoke _AS_ECHO_PREPARE.
562 Don't set as_nl, since _AS_ECHO_PREPARE does that now.
563 (_AS_PREPARE): Comment that _AS_ECHO_N_PREPARE is just for user code.
564 (AS_ECHO, AS_ECHO_N, _AS_ECHO_PREPARE): New macros.
565 * tests/c.at (AC_PROG_CPP without warnings, AC_PROG_CPP via CC):
566 Double-quote strings that would otherwise contain M4 comments.
567 * tests/m4sh.at (AS_ECHO and AS_ECHO_N): New test.
569 * configure.ac (AC_INIT): Bump to 2.61a.
572 2006-11-17 Paul Eggert <eggert@cs.ucla.edu>
576 * configure.ac (AC_INIT): Bump to 2.61.
579 * tests/autotest.at (Macro with backslash in a test title):
580 Comment out for now, as this tests neither fails nor passes
581 reliably. Problem reported by Ralf Wildenhues.
583 2006-11-16 Paul Eggert <eggert@cs.ucla.edu>
585 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ENABLE): Fix some typos
586 in previous change, which caused test failures.
588 2006-11-16 Stepan Kasal <kasal@ucw.cz>
590 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Factor out
591 code for --enable, --disable, --with, and --without to...
592 (_AC_INIT_PARSE_ENABLE): ... a new macro.

659 * tests/mktests.sh (ac_exclude_list): Exclude AC_PROG_CXX_C_O, for
660 benefit of platforms like Solaris+GCC where it is common to have a
661 non-working g++ installation.
663 2006-11-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
664 and Joel E. Denny <jdenny@ces.clemson.edu>
665 and Paul Eggert <eggert@cs.ucla.edu>

673 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Set
674 ac_cv_type_long_long_int to 'yes' instead of 'cross-compiling'.
675 Imported from a similar patch to gnulib by Bruno Haible.

686 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT): Detect bug in
687 Tandem NonStop Kernel (OSS) cc -O circa 2004, reported by
690 2006-10-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
692 * tests/torture.at (Configuring subdirectories): Do not skip
693 Automake 1.10 nor future Automake 11.1 (sic).

696 and Stepan Kasal <kasal@ucw.cz>
698 Handle special characters in test case titles correctly.
699 * lib/autotest/general.m4 (AT_INIT): M4-quote and AS_ESCAPE AT_help_all
701 (AT_SETUP): M4-quote and AS_ESCAPE the title properly everywhere.
702 * tests/autotest.at (AT_CHECK_AT_TITLE): Add EXPANDED-TITLE-TO-TEST

706 Single-quote in a test title,
707 Double-quote in a test title): Don't expect failure anymore.
708 (Backslash in a test title): Put a non-whitespace character after the
709 backslash so that Bourne shells might actually see it as an escape
711 (Brackets in a test title,
712 Pound in a test title,
713 Comma in a test title,
714 Quoted Macro in a test title,
715 Macro in a test title,
716 Macro with single-quote in a test title): New tests.
717 (Macro with backquote in a test title,
718 Macro with double-quote in a test title,
719 Macro with backslash in a test title): New tests expected to fail.
720 * tests/torture.at (#define header templates): M4-quote this title in
721 AT_SETUP call so that no M4 code is commented inadvertently somewhere.
722 The visible effect was a stray [] in the testsuite output.
724 2006-10-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
726 * doc/autoconf.texi (Limitations of Builtins): Do not invoke
727 `trap ... 0' inside a function, for AIX sh.
729 2006-10-26 Paul Eggert <eggert@cs.ucla.edu>
731 * tests/base.at (AC_COMPUTE_INT): Test **0** rather than 1 / 0,
732 since powerpc-apple-darwin8-gcc-4.0.1 (Apple Computer, Inc. build
733 5363) simply issues a warning when dividing by zero at compile
734 time. Problem reported by Elias Pipping.
736 2006-10-26 Eric Blake <ebb9@byu.net>
739 * doc/autoconf.texi (Evaluation Macros): Improve the example to
740 show effect on macros that expand with commas.

763 * tools/trace.at (autoconf --trace: user macros): Test `$%'.
765 2006-10-24 Paul Eggert <eggert@cs.ucla.edu>
767 * lib/autoconf/specific.m4 (_AC_SYS_LARGEFILE_MACRO_VALUE):
768 If FUNCTION-BODY is nonempty, use AC_LINK_IFELSE rather than
769 AC_COMPILE_IFELSE, to work around problem with OSF/1 4.0F fseeko
770 reported by Nelson H. F. Beebe for Coreutils 6.4.
772 * tests/tools.at (autoconf --trace: user macros): Remove test
773 for tracing multiline macros, since m4 1.4.7a uses a different
774 way to number lines. Problem reported by Ralf Wildenhues.
776 2006-10-24 Stepan Kasal <kasal@ucw.cz>
778 * bin/autom4te.in (handle_m4): Do not redirect stdin to
779 /dev/null since the heuristics for interactive behaviour was

801 * doc/autoconf.texi (Caching Results): Likewise.
802 * lib/autoconf/general.m4 (_AC_CACHE_CHECK_INT): Renamed from
803 AC_CACHE_CHECK_INT, since it's no longer public.
804 * lib/autoconf/types.m4: All uses of AC_CACHE_CHECK_INT changed.
805 * tests/base.at (AC_COMPUTE_INT): Test this, not AC_CACHE_CHECK_INT.

835 * lib/m4sugar/m4sh.m4 (AS_LITERAL_IF): Expand $1 before
836 looking for special shell characters.
837 * lib/autoconf/functions.m4 (AC_CHECK_FUNC): Do not expand the
838 macro defined by AS_VAR_PUSHDEF before passing it as a

850 2006-10-14 Paul Eggert <eggert@cs.ucla.edu>
852 (Imported from Automake.)
853 * build-aux/install-sh (posix_mkdir): Reject FreeBSD 6.1 mkdir -p -m,
854 which incorrectly sets the mode of an existing destination
855 directory. In some cases the unpatched install-sh could do the
856 equivalent of "chmod 777 /" or "chmod 0 /" on a buggy FreeBSD
857 system. We hope this is rare in practice, but it's clearly worth
858 fixing. Problem reported by Alex Unleashed in
859 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00012.html>.
860 Also, don't bother to check for -m bugs unless we're using -m;
861 suggested by Stepan Kasal.

883 2006-09-16 Karl Berry <karl@gnu.org>
884 * doc/fdl.texi (ADDENDUM): switch to @heading from @appendixsubsec,
885 to avoid sectioning errors.

894 (\lquoteChar, \rquoteChar, \dashChar, \underChar: new \chardef's.
895 (\code): must use new \...Char values, since now ` is active.
897 2006-08-26 Karl Berry <karl@gnu.org>
898 * build-aux/texinfo.tex (\textdegree): New command.
900 2006-08-12 Karl Berry <karl@gnu.org>

910 added to the template can get mangled.
912 2006-10-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
914 * lib/autoconf/functions.m4 (AC_FUNC_OBSTACK): In the test,
915 include the default headers, and redefine obstack_chunk_alloc
916 and obstack_chunk_free. Fixes false failure with glibc.
918 2006-10-12 Paul Eggert <eggert@cs.ucla.edu>
920 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Set as_executable_p,

938 (AS_EXECUTABLE_P): Use as_test_x rather than as_executable_p.
939 (_AS_TEST_PREPARE): Set as_test_x rather than as_executable_p.
940 Use a better substitute, by inspecting the output of "ls"
941 rather than just using ":".
942 * lib/autoconf/general.m4 (_AC_LINK_IFELSE): Use AS_TEST_X
943 rather than AS_EXECUTABLE_P, since we needn't worry about
944 non-regular files here.
946 * NEWS: Autoconf-generated shell scripts no longer export BIN_SH,
947 due to configuration hassles with this. See Tonya Underwood's report
948 <http://lists.gnu.org/archive/html/bug-autoconf/2006-10/msg00003.html>.

967 problems with mkdir -p -m.
969 2006-10-06 Paul Eggert <eggert@cs.ucla.edu>
971 * lib/autoconf/c.m4 (_AC_PROG_PREPROC_WORKS_IFELSE): Remove
972 comment about ac_cpp_err; it was incorrect, and anyway
973 ac_cpp_err is being removed below.
974 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE): Don't
975 set ac_cpp_err to 'yesyes' if preproc_warn_flag and werror_flag
976 are both 'yes'. In fact, don't bother setting ac_cpp_err at all;
978 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't log our funky tests
979 with werror_flag and conftest.err and so forth. This is more
980 compatible with how _AC_PROG_PREPROC_WORKS_IFELSE behaves,
981 and anyway the user shouldn't normally want to see this gorp logged.
982 Problem reported by Ralf Wildenhues.
983 * lib/autoconf/lang.m4 (AC_LANG_WERROR): werror_flag's default is
984 empty, not 'no', since the rest of the code uses 'test -z'.

988 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):

995 * lib/m4sugar/m4sh.m4 (_AS_TEST_PREPARE): Use "test -x /" rather
996 than creating a file to use with test -x; this is much faster.

1255 broken lex libraries like native ia64-hp-hpux11.22; see
1256 <http://sources.redhat.com/ml/binutils/2003-12/msg00337.html>, and

1423 2006-08-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1425 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): `config.status
1426 --help' should mention that `--version' outputs configuration
1427 settings. Report by Bruno Haible.
1429 2006-08-06 Paul Eggert <eggert@cs.ucla.edu>
1431 Fix test suite failures reported by Pierre in
1432 <http://lists.gnu.org/archive/html/bug-autoconf/2006-08/msg00005.html>.
1433 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't claim
1434 the compiler created a file "b.out" when it didn't create anything
1436 * lib/autoconf/specific.m4 (AC_SYS_INTERPRETER):
1437 Discard stderr too, when invoking the test script.
1439 2006-08-05 Alexandre Julliard <julliard@winehq.org> (tiny change)
1441 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Fixed a typo
1442 in the restoring of the werror flag.
1444 2006-07-24 Paul Eggert <eggert@cs.ucla.edu>
1446 * doc/autoconf.texi (Volatile Objects): Be even a little
1447 less skeptical about "volatile", after discussion with
1448 Bruno Haible on bug-gnulib.
1449 (Limitations of Usual Tools): Warn about sed stripping
1450 leading white space from text. From Bruno Haible.
1452 2006-07-20 Paul Eggert <eggert@cs.ucla.edu>
1454 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Don't use -R if the
1455 compiler complains about it, even if things works after the
1456 complaint. Problem reported by Peter O'Gorman.
1458 * doc/autoconf.texi (Preset Output Variables): Document CFLAGS,
1459 CPPFLAGS, and LDFLAGS better. Problem reported by Bruno Haible.
1460 Similarly for CXXFLAGS, OBJCFLAGS, ERLCFLAGS.
1462 2006-07-17 Paul Eggert <eggert@cs.ucla.edu>
1464 * lib/autoconf/libs.m4 (AC_PATH_XTRA): Do the check for space
1465 after -R regardless of host. Patrick Welche reports that this
1466 fixes things on NetBSD 3.99.
1468 * NEWS: Recommend M4 1.4.5.
1470 * doc/autoconf.texi (Introduction, Why GNU M4): Likewise.
1471 * tests/tools.at (autom4te cache): Update wording of diagnostic
1474 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1476 * doc/autoconf.texi (C Compiler): Add a ref to Volatile Objects
1477 under AC_C_VOLATILE.
1478 (Volatile Objects): Be a little less skeptical about what
1479 "volatile" means. Derived from thoughts by Ben Pfaff in
1480 <http://lists.gnu.org/archive/html/bug-gnulib/2006-07/msg00092.html>.
1482 2006-07-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1484 * doc/autoconf.texi: Fix some typos.
1486 2006-07-07 Paul Eggert <eggert@cs.ucla.edu>
1488 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1489 more globally, since the 2006-06-30 patch didn't suffice. Problem
1490 reported by Keith Marshall. Also, don't bother with builddir2,
1491 since it shouldn't be needed any more.
1493 2006-07-07 Paolo Bonzini <bonzini@gnu.org>
1495 * doc/autoconf.texi (Generic compiler characteristics):
1496 Document AC_COMPUTE_INT. Fix wrong statements on Default
1497 Includes for AC_CHECK_SIZEOF and AC_CHECK_ALIGNOF.
1499 * lib/autoconf/general.m4 (AC_COMPUTE_INT): New.
1500 (_AC_COMPUTE_INT): Add obsoletion warnings.
1501 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF, AC_CHECK_ALIGNOF): Use
1504 * NEWS: Document change.
1506 2006-07-05 Paul Eggert <eggert@cs.ucla.edu>
1508 * doc/autoconf.texi (Volatile Objects): New section.
1510 * NEWS: Document previous change.
1512 2006-07-02 Paul Eggert <eggert@cs.ucla.edu>
1514 * lib/autoconf/types.m4 (AC_TYPE_LONG_LONG_INT):
1515 Require that long long int be at least 64 bits wide. C99 requires
1516 this and enough programs depend on it so we should check for it.
1517 Bruno Haible reports in
1518 <http://lists.gnu.org/archive/html/bug-gnulib/2006-06/msg00286.html>
1519 that long long int is 32 bits wide with some nonstandard compilers.
1520 (AC_TYPE_UNSIGNED_LONG_LONG_INT): Likewise.
1522 2006-06-30 Paul Eggert <eggert@cs.ucla.edu>
1524 * tests/torture.at (Configuring subdirectories): Set CONFIG_SITE
1525 to a nonexistent file, so that we don't have to worry about
1526 a local site configuration that doesn't use /usr/local.
1527 Problem reported by Keith Marshall in
1528 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00133.html>.
1530 2006-06-28 Paul Eggert <eggert@cs.ucla.edu>
1532 * doc/autoconf.texi: Be more consistent about using @acronym with
1533 "HP" and "HP-UX". Remove mention of OSF; the old version wasn't
1534 quite right (it talked about "OSF/Tru64", even though the
1535 operating systems were called OSF/1, Digital UNIX, and Tru64 UNIX,
1536 and it even mentioned "OSF 4"!) and at this point there's little
1537 reason to talk about OSF any more, since it died in 1994.
1538 (Specific Compiler Characteristics): Simplify example of
1539 negative-size array.
1540 (File Descriptors): Reorder to make the text flow better.
1541 Remove joke about "appreciate the various levels"; I didn't get it.
1542 Add remark about HP-UX sh -x bug with stderr noted by Bob Proulx in
1543 <http://lists.gnu.org/archive/html/bug-coreutils/2006-06/msg00225.html>.
1544 (File Descriptors, Limitations of Usual Tools):
1545 Tone down the advice against renaming or removing open files.
1546 (Limitations of Usual Tools): Add a new section, on 'rm'.
1548 2006-06-26 Stepan Kasal <kasal@ucw.cz>
1550 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Use -lX11, not
1551 -lXt in LIBS, idea from Karsten Hopp; this was due since
1554 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
1555 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
1556 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
1557 (which belong to Xt, not X itself). See Debian bug 327655.
1559 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1561 * configure.ac (AC_INIT): Bump to 2.60a.
1564 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1568 * configure.ac, NEWS: Update.
1570 2006-06-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1572 * config/texinfo.tex: Sync from upstream.
1574 * bin/autom4te.in (handle_traces): Transform the `@S|@'
1575 quadrigraph correctly in traces.
1577 * NEWS, lib/Autom4te/C4che.pm, lib/autoconf/functions.m4:
1580 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Expand tests for
1581 datarootdir-related errors only if AC_DATAROOTDIR_CHECKED is
1583 * doc/autoconf.texi (Changed Directory Variables): New node,
1584 to document the whole `datarootdir' business a bit better.
1586 * tests/torture.at (datarootdir workaround): Extend test.
1587 Prompted by report by Alexandre Julliard.
1589 2006-06-22 Paul Eggert <eggert@cs.ucla.edu>
1591 * lib/autoconf/c.m4 (_AC_PROG_CC_C89): Check for C89 incompatibility
1592 when using default mode of IBM C 6 for AIX. Problem and two-line
1593 fix reported by Larry Jones.
1595 2006-06-22 Alexandre Julliard <julliard@winehq.org>
1597 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Avoid warning
1598 about literal '${datarootdir}' if a definition is found in the
1601 2006-06-20 Paul Eggert <eggert@cs.ucla.edu>
1603 * NEWS: Use "M4" rather than "m4" when appropriate.
1604 Problem reported by Eric Blake.
1605 * doc/autoconf.texi: Likewise.
1606 Use @acronym around BSD, GCC, and GNU when appropriate.
1607 (Why GNU M4): Renamed from "Why GNU m4".
1608 (Redefined M4 Macros): Mention that Posix
1609 m4wrap takes only 1 argument, but GNU M4 1.4.x takes more.
1610 (Buffer Overruns): Mention size_t and ptrdiff_t as alternatives
1613 2006-06-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1615 * bin/autom4te.in (handle_output): Do not forbid the empty
1617 * tests/tools.at (autoconf: the empty token): New test.
1619 2006-06-20 Stepan Kasal <kasal@ucw.cz>
1621 * lib/m4sugar/m4sugar.m4 (m4_init): Merge the two m4_wrap
1622 calls, so that we do not care whether they are LIFO or FIFO;
1623 in the m4_wrap, do not check which diversion is the topmost
1624 one, just check that the stack is balanced at the end.
1625 * lib/m4sugar/m4sh.m4 (AS_INIT): We are going to change the
1626 base diversion forever--pop the previous diversion before
1627 opening the new one; consequently, remove the m4_wrap call.
1628 * lib/autotest/general.m4 (AT_INIT): Likewise.
1629 * tests/m4sugar.at: Do not use
1630 m4_wrap([m4_diversion_pop([..])]), for educational purposes.
1632 2006-06-19 Paul Eggert <eggert@cs.ucla.edu>
1633 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1635 * NEWS: Document that m4wrap/m4_wrap might not be LIFO.
1636 * doc/autoconf.texi (Redefined M4 Macros): Likewise.
1637 Rework example of m4wrap token-pasting trouble so that it doesn't
1638 care whether it's LIFO or FIFO.
1639 Fix some "contrary to"s that are awkward in English.
1641 2006-06-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1643 * lib/autoconf/types.m4 (_AC_TYPE_INT): Set `$ac_cv_c_int$1_t'
1644 to `yes' instead of `int$1_t' if the type is found, for more
1645 consistent configure output (where $1 is the number of bits).
1646 (_AC_TYPE_UINT): Likewise for `uint$1_t'.
1647 Suggested by Bruno Haible.
1649 * lib/autoconf/types.m4 (_AC_TYPE_UNSIGNED_INT): Solaris 2.5.1
1650 needs _UINT8_T and _UINT64_T defines as well, to avoid clashes
1651 with system headers. Report by Bruno Haible.
1653 2006-06-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1655 * config/config.guess, config/config.sub: Sync from upstream.
1657 * bin/Makefile.am (autoconf.in): Use `--melt' for autom4te,
1658 in order to avoid picking up an older installed frozen m4sh.m4f.
1659 Besides an outdated shell startup, this could have been created
1660 by an earlier M4 version with incompatible frozen file format.
1662 2006-06-16 Paul Eggert <eggert@cs.ucla.edu>
1664 * README: Recommend m4 1.4.4 instead of 1.4.3..
1665 * doc/autoconf.texi: Likewise.
1666 (Special Chars in Names): Say that $(.FOO) is portable, as
1667 suggested by Stepan Kasal.
1668 (Installation Directory Variables, Build Directories):
1669 (Automatic Remaking, Subdirectories, Fortran Compiler):
1670 (Making testsuite Scripts, Defining Directories):
1671 Quote variable usages better.
1672 (Making testsuite Scripts): Add clean-local rule to makefile
1673 snippet, by Eric Blake.
1674 (Installation Directory Variables): Fix table item font.
1675 Reword slightly to clarify. Generalize advice about
1676 not using special characters to include all file-related
1677 vars, not just VPATH.
1678 (Special Chars in Variables): Warn about special characters in
1680 (Assignments): Clarify default-value example as suggested by
1682 <http://lists.gnu.org/archive/html/autoconf-patches/2006-06/msg00072.html>.
1683 (Special Shell Variables): Note leading ./ or ../, as suggested
1685 (Limitations of Builtins): Under cd, warn about CDPATH.
1686 (The Make Macro MAKEFLAGS): Untabify. Problem reported by
1689 2006-06-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1691 * doc/autoconf.texi (Configuration Actions): Remove duplicate
1692 `@var', for texi2html.
1693 (Systemology): Some more word wrapping, for DVI output.
1694 (autom4te Invocation): The short option for `--melt' is `-M',
1697 2006-06-15 Paul Eggert <eggert@cs.ucla.edu>
1699 * doc/autoconf.texi: More formatting and English tweaks,
1700 many suggested by Ralf Wildenhues.
1701 Reword to avoid "@code{...}'s" and the like, since it's ugly
1702 with Emacs info mode. discontents -> woes.
1703 Put a few "will"s back. time stamp -> timestamp.
1704 side-effect -> side effect.
1706 2006-06-14 Paul Eggert <eggert@cs.ucla.edu>
1708 * doc/autoconf.texi (Initializing configure, Shell Substitutions):
1709 Warn about $@ not persisting. Problem reported by Julien Danjou in
1710 <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=372179>.
1711 (Special Chars in Names): Renamed from Leading _ in Macro Names.
1712 Mention other special chars, too.
1714 2006-06-14 Eric Blake <ebb9@byu.net>
1716 * doc/autoconf.texi (The Make Macro MAKEFLAGS): New node.
1718 2006-06-13 Paul Eggert <eggert@cs.ucla.edu>
1720 * doc/autoconf.texi: Some systematic minor improvements, as
1721 follows. Use "makefile" when talking about makefiles
1722 generally (which might be named "makefile" or "Makefile" or even
1723 "foo.mk"), "Makefile" when talking about a specific makefile
1724 called "Makefile". This unclutters the text from weird quotes
1725 (e.g., "`Makefile's" in info mode). Similarly, use "@var{foo}
1726 values" rather than "@var{foo}s" and similar constructs containing
1727 "}s". Use "Make rules" rather than "Makefile rules". Minor
1728 English-language improvements. Change the prefix "sub-" to "sub"
1730 Put blank lines around examples more consistently.
1731 Avoid "rather" and "very" as intensifiers.
1732 Avoid "will" as an auxiliary.
1733 (Limitations of Make): Split this node into....
1734 (Portable Make, $< in Ordinary Make Rules, Failure in Make Rules):
1735 (Leading _ in Macro Names, Backslash-Newline-Newline):
1736 (Backslash-Newline Comments, Long Lines in Makefiles):
1737 (Macros and Submakes, The Make Macro SHELL, Comments in Make Rules):
1738 (obj/ and Make, make -k Status, VPATH and Make):
1739 (VPATH and Double-colon, $< in Explicit Rules):
1740 (Automatic Rule Rewriting, OSF/Tru64 Directory Magic):
1741 (Make Target Lookup, Single Suffix Rules, Timestamps and Make):
1742 New nodes, resulting from splitup of Limitations of Make.
1743 All cross-references changed. Raise the top node from
1744 a section to a chapter, and all subnodes accordingly.
1745 Redo the introductory wording to match the new organization.
1746 (Installation Directory Variables): Use an example that is
1747 closer to what Autoconf actually does. Mention that VPATH's
1748 value should not contain metacharacters or white space.
1749 (Fortran Compiler): Fix a VPATH bug in an example.
1750 (Leading _ in Macro Names): Mention that this problem is no longer
1751 of practical concern.
1752 (VPATH and Make): Reword the advice to make it clearer
1753 that Autoconf and Automake support VPATH in non-GNU make, but
1754 many packages have bugs in this area.
1755 ($< in Explicit Rules): Refer to Build Directories rather
1756 than using a (non-VPATH-safe) example.
1757 (Automatic Rule Rewriting): Mention the sort of disaster that
1758 can ensue with Solaris-style rule rewriting with VPATH.
1760 2006-06-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1762 * doc/install.texi (Compilers and Options): Weaken the
1763 suggestion to use GNU make for VPATH builds.
1765 * lib/autom4te.in (Automake-preselections): Add AM_PROG_CXX_C_O,
1766 AM_PROG_F77_C_O, AM_PROG_FC_C_O, AC_FC_SRCEXT, AC_FC_FREEFORM.
1768 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Fix M4 quotation
1769 in regular expression.
1771 2006-06-08 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1773 * doc/autoconf.texi (Installation Directory Variables):
1774 Drop extra @samp from `@table @samp' item.
1775 (Limitations of Usual Tools): Comment fix.
1776 Do not nest @samp just to point to other table items.
1777 (Writing testsuite.at) <AT_CHECK>: The second argument to
1778 `@dvar' is already @samp'ed.
1779 (Making testsuite Scripts) <AC_CONFIG_TESTDIR>: Likewise,
1780 do not use @var in the second argument.
1782 2006-06-07 Paul Eggert <eggert@cs.ucla.edu>
1784 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Look for
1785 $as_shell.exe too. Problem reported by Andreas Buening in
1786 <http://lists.gnu.org/archive/html/autoconf/2006-06/msg00038.html>.
1788 2006-06-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1790 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA): Work around
1791 `unused variable' compiler warning, for `-Wall -Werror'.
1792 Reported by Jaap Haitsma in
1793 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00012.html>.
1795 2006-06-06 Paul Eggert <eggert@cs.ucla.edu>
1797 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Remove core file, in
1798 case the compiler dumps core. Problem reported for
1799 OpenServer 5.0.7 by Tim Rice in
1800 <http://lists.gnu.org/archive/html/bug-autoconf/2006-06/msg00019.html>.
1801 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE, _AC_LINK_IFELSE):
1804 2006-06-06 Tim Rice <tim@multitalents.net>.
1806 * lib/freeze.mk: Quiet check-forbidden-patterns so the string
1807 "ERROR" only shows up in "make check" output if there is an
1810 2006-06-06 Eric Blake <ebb9@byu.net>
1812 * tests/tools.at (automatically allowed tokens): Fix typo.
1814 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1816 * NEWS: Don't blame non-GNU VPATH compatibility issues on Automake.
1818 * doc/autoconf.texi (Integer Overflow): Mention that INT_MIN % -1

1831 * config/texinfo.tex: Sync from upstream.
1833 * bin/autoreconf.in: Trace `LT_CONFIG_LTDL_DIR'; if it has been
1834 seen, invoke libtoolize with `--ltdl' argument.
1835 * lib/autom4te.in (Autoreconf-preselections): Adjust.
1837 Suggested by Eric Blake.
1839 2006-06-05 Paul Eggert <eggert@cs.ucla.edu>
1841 * NEWS: Whoops! AC_FUNC_STRNLEN isn't obsolescent. Problem

1881 * NEWS: GNU make now recommended for VPATH builds.
1882 Mention that some macros are now documented to be obsolescent.
1883 * doc/autoconf.texi:
1884 Prefer "current" to "modern" to describe
1885 currently-used (albeit perhaps old-fashioned) hosts.
1886 Mention which ancient features no longer need to be worried about.
1887 setgid -> set-group-ID
1888 setuid -> set-user-ID (these are the Posix terms)
1889 Fix some misuses of "only".

1902 Mention that it's now safe to use 3 and 4.
1903 (Limitations of Usual Tools): cp -r is now specified by Posix.
1904 Omit longwinded and obsolescent discussion of cp -f.
1905 Modernize discussion of expr, ls.
1906 (Limitations of Make): Modernize discussion of VPATH builds.
1907 Mention $? as a workaround in some cases.
1908 * doc/install.texi (Basic Installation):
1909 Mention "./configure; make; make install" first. Be more
1910 specific about why this file is generic. Remove unnecessary
1911 parens. Remove misleading "only". Remove obsolete advice
1912 about csh. Don't say "configure" takes awhile; say it
1913 might take a while. Suggest CFLAGS=-g rather than CFLAGS=-O2,
1914 and CC=c99 rather than CC=c89, as these are blessed by current
1915 Posix. Recommend GNU make if doing a VPATH build.
1917 2006-06-03 Paul Eggert <eggert@cs.ucla.edu>
1919 * doc/autoconf.texi: Use a consistent style "$ @kbd{...}" for
1920 examples involving shell prompts.
1922 2006-06-02 Stepan Kasal <kasal@ucw.cz>
1923 and Paul Eggert <eggert@cs.ucla.edu>
1925 * doc/autoconf.texi (Here-Documents): Add details about the
1926 pre-ksh93g bug. Reword slightly to make it clearer. Consistently
1927 use "here-documents" instead of "here documents".
1929 2006-06-01 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1931 * config/texinfo.tex, doc/standards.texi: Sync from upstream.
1933 2006-06-01 Paul Eggert <eggert@cs.ucla.edu>
1935 * doc/autoconf.texi (File System Conventions): Warn about ":"
1936 anywhere in directory names.
1938 2006-05-31 Paul Eggert <eggert@cs.ucla.edu>
1940 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be even more conservative
1941 about quoting the case statement, just in case.
1942 * doc/autoconf.texi (Here-Documents): Mention that the ksh bug
1943 was fixed in ksh93g; reported by Ralf Wildenhues.
1945 2006-05-31 Stepan Kasal <kasal@ucw.cz>
1947 * doc/autoconf.texi (System Services): Do not document
1948 overriding EXEEXT via ac_cv_exeext=ext.
1949 (Particular Programs) <AC_PROG_MKDIR_P>:
1950 Document that ${MKDIR_P} understands --.
1951 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Improve the
1954 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1956 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Guard against test
1957 argument with leading hyphen. Problem reported by Paul Eggert.
1959 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1961 * lib/autoconf/general.m4 (_AC_DO_ECHO): Be more conservative
1962 about quoting ac_try: quote all of it, if any of it seems suspicious.
1963 This means we don't have to worry about ${ or sed any more.
1964 Also, double-quote the case statement, to work around misuses via
1965 underquoting as reported by Ralf Wildenhues in
1966 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00169.html>.
1967 (_AC_EVAL_STDERR): Revert, since evidently some packages rely on this
1968 undocumented and dangerous macro.
1969 Problem reported by Ralf Wildenhues in
1970 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00168.html>.
1972 2006-05-31 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1974 * lib/m4sugar/m4sh.m4 (_AS_DIRNAME_PREPARE): Check whether
1975 `dirname -- /' returns `/', for SunOS dirname scripts that escaped.
1976 Report by Sam Sirlin <sam@kalessin.jpl.nasa.gov>.
1978 2006-05-30 Paul Eggert <eggert@cs.ucla.edu>
1980 * lib/autoconf/general.m4: Revert AC_TRY_EVAL and AC_TRY_COMMAND,
1981 since evidently some packages rely on the old, broken behavior.
1982 Problem reported by Ralf Wildenhues in
1983 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00160.html>.
1984 (AC_TRY_EVAL, AC_TRY_COMMAND, _AC_EVAL): Go back to the
1985 pre-2006-05-26 definitions, but leave in the comments that
1986 these macros are dangerous and should not be used.
1987 (_AC_DO_ECHO): Renamed from _AC_EVAL_ECHO. All callers changed.
1988 (_AC_DO): Renamed from _AC_EVAL. All callers changed.
1989 (_AC_DO_STDERR): Renamed from _AC_EVAL_STDERR. All callers changed.
1990 (_AC_DO_VAR): Renamed from AC_TRY_EVAL.
1991 (_AC_DO_TOKENS): Renamed from AC_TRY_COMMAND.
1993 2006-05-29 Paul Eggert <eggert@cs.ucla.edu>
1995 * lib/autoconf/status.m4 (AC_OUTPUT_MAKE_DEFS): Rewrite to avoid
1996 the use of 'tr', since this is our only use of 'tr'.
1998 2006-05-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
1999 and Paul Eggert <eggert@cs.ucla.edu>
2001 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES_PREPARE):
2002 Don't assume 'grep' works on long lines, since AIX grep doesn't.
2004 2005-05-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2006 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Do not use `grep' on
2007 the output file in the `${datarootdir}' test.
2009 2005-05-28 Stepan Kasal <kasal@ucw.cz>
2010 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2012 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If we have not seen
2013 mention of `datarootdir' in the input file(s), but literal
2014 `${datarootdir}' in the output file, and we haven't warned yet,
2015 then warn as well: the user may have (erroneously) used
2016 `AC_SUBST([mydatadir], [$datadir/my])' instead of the correct
2017 `AC_SUBST([mydatadir], ['${datadir}/my'])'.
2018 * tests/torture.at (datarootdir workaround): Extend this test.
2021 2006-05-27 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2022 and Paul Eggert <eggert@cs.ucla.edu>
2024 * doc/autoconf.texi (autoheader Invocation): The first argument to
2025 `AC_DEFINE_UNQUOTED' need not be a literal. Mention the
2026 alternatives and clear up the language a bit.
2028 2006-05-27 Paul Eggert <eggert@cs.ucla.edu>
2030 * NEWS: Reword notice for AC_TRY_COMMAND, AC_TRY_EVAL,
2031 ac_config_guess, ac_config_sub, ac_configure.
2032 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS):
2033 Fix typo that prevented an unnecessary space from being removed.
2034 Problems reported by Ralf Wildenhues in:
2035 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00143.html
2037 2006-05-26 Paul Eggert <eggert@cs.ucla.edu>
2039 * doc/autoconf.texi (Particular Programs, Limitations of Usual Tools):
2040 Use better wording to talk about AC_PROG_MKDIR_P's thread-safety.
2041 Don't use the term "thread-safe" to talk about mkdir race
2042 conditions, since the problem is more a process than a thread
2043 issue. Problem reported by Stepan Kasal in:
2044 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00088.html
2045 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Use code that mimics
2046 the test for 'install' more closely. Look at MKDIR_P first.
2047 Look in the PATH, and at /opt/sfw/bin.
2048 Look for a 'gmkdir' program as well (Solaris 10 /opt/sfw/bin/gmkdir).
2049 Don't bother to try mkdir -p, since we already check mkdir --version;
2050 just look at the version number. (There's no easy way to check
2051 for race-free implementations.)
2052 * tests/tools.at (autoconf: subdirectories): Adjust to above
2053 changes, since MKDIR_P now might end in "/mkdir -p".
2055 * doc/autoconf.texi (autoheader Invocation): Mention that the
2056 first arg of AC_DEFINE_UNQUOTED must be a literal.
2057 Problem reported by Ben Pfaff in
2058 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00090.html>.
2060 * NEWS: Mention that AC_TRY_COMMAND and AC_TRY_EVAL may be removed.
2061 * doc/autoconf.texi (Special Chars in Variables): New section.
2062 (Preset Output Variables): Warn about special chars in CPPFLAGS.
2063 (Installation Directory Variables): Quote $(datadir) better.
2064 (Limitations of Builtins): Describe some of eval's trickiness.
2066 * lib/autoconf/c.m4 (AC_PROG_CC_C_O): Simplify quoting.
2067 * lib/autoconf/fortram.m4 (_AC_PROG_FC_V_OUTPUT): Likewise.
2068 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Put leading space
2069 in front of every arg, not just trailing args. Quote apostrophes.
2070 (_AC_EVAL_ECHO): New macro.
2071 (_AC_EVAL, AC_EVAL_STDERR): Use it. Quote arg of eval.
2072 (AC_TRY_EVAL, AC_TRY_COMMAND): Mention that these macros might get
2074 (_AC_LINK_IFELSE): Use proper rule for shell continuation lines,
2075 exposed by quoting of eval argument. Put the command on line line
2077 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): Use eval more safely.
2078 (_AC_PATH_X, AC_PATH_X): Quote more safely.
2079 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Use eval more safely.
2080 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Don't use eval.
2081 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Minor style change.
2082 Handle special chars in prefix, ac_srcdir, ac_aux_dir.
2083 Use eval more safely.
2084 (_AC_OUTPUT_CONFIG_STATUS): Adjust to above changes.
2085 * lib/m4sugar/m4sh.m4 (AS_VAR_GET): Note that this API needs
2087 * tests/base.at (AC_TRY_COMMAND): Use proper rule for shell continuation
2088 lines, exposed by quoting of eval argument.
2090 2006-05-26 Stepan Kasal <kasal@ucw.cz>
2091 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2093 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Drop the
2094 initialization of `ac_cv_exeext', do not override it if it was
2095 already set, unless it was set to `no', for compatibility with
2096 Autoconf-2.13, and comment this.
2097 Do not export `ac_cv_exeext', Libtool hasn't needed this for years.
2098 (_AC_COMPILER_EXEEXT_DEFAULT): Likewise, do not export it.
2099 (_AC_COMPILER_EXEEXT_WORKS, _AC_COMPILER_EXEEXT_CROSS): Typos.
2100 * doc/autoconf.texi (Compilers and Preprocessors) <EXEEXT>:
2101 Document that this test may be overridden by setting
2104 2006-05-26 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2106 Revert these two patches:
2108 2006-04-06 Eric Blake <ebb9@byu.net>
2109 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_O): Inside cache
2110 check, s/ac_exeext/ac_cv_exeext/. Fixes regression introduced
2113 2006-04-01 Stepan Kasal <kasal@ucw.cz>
2114 Clean up _AC_COMPILER_EXEEXT* macros.
2115 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Don't try to
2116 detect exeext, it will be done by _AC_COMPILER_EXEEXT_O; just set
2117 ac_file to the name of the default output file and call
2118 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
2119 initial `rm' of the candidate files...
2120 (_AC_COMPILER_EXEEXT): ... here and simplify them. Moreover, use
2121 the same list in subsequent `rm' calls, and for the temporary
2122 redefinition of ac_clean_files; call _AC_COMPILER_OBJEXT at the end,
2123 and don't call the other _AC_COMPILER_EXEEXT_* macros directly, use...
2124 (_AC_COMPILER_EXEEXT_TESTS): ... this new macro.
2125 (_AC_COMPILER_EXEEXT_O): Don't export ac_cv_exeext, it's not needed (or
2126 no longer needed) by libtool. Make it a cache check.
2127 (_AC_COMPILER_EXEEXT_CROSS): Remove the comment, it was obviously
2128 copied here by mistake.
2129 (AC_NO_EXECUTABLES): Redefine _AC_COMPILER_EXEEXT_TESTS, not
2130 _AC_COMPILER_EXEEXT.
2131 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX, AC_PROG_OBJC): Do not call
2132 _AC_COMPILER_OBJEXT directly.
2133 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
2135 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2137 * doc/autoconf.texi (Limitations of Usual Tools) < sed (`t')>:
2138 Fix description of how the buggy `sed' works.
2140 2006-05-25 Noah Misch <noah@cs.caltech.edu>
2144 * lib/Autom4te/XFile.pm (lock): Allow EOPNOTSUPP, besides
2145 ENOLCK. Only mention `make -j' when applicable. Only raise
2146 fatal errors when `make -j' is involved. Improve error message.
2148 2006-05-25 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2150 * doc/autoconf.texi (Here-Documents): We now know more about
2151 the variable expansion in here documents bug.
2152 Thanks to Tim Rice and Stepan Kasal.
2154 * doc/autoconf.texi (Making testsuite Scripts): Add an example
2155 how to use TESTSUITEFLAGS. Suggested by Eric Blake.
2157 2006-05-24 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2159 * tests/autotest.at (Multiline command from M4 expansion):
2160 No failure to be expected if the shell quotes newlines in
2161 commands in the `set -x' output. Report by Tim Rice.
2164 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2166 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Don't use shell
2167 expansion in the here-documents used by config.status, as that
2168 runs afoul of the Korn shell version M-12/28/93d bug described in
2169 the Autoconf manual, and this in turn causes a Coreutils 5.95 build to
2170 fail as described by Tim Rice and diagnosed by Ralf Wildenhues in
2171 <http://lists.gnu.org/archive/html/bug-autoconf/2006-05/msg00082.html>.
2173 2006-05-23 Jim Meyering <jim@meyering.net>
2175 * lib/autoconf/functions.m4 (AC_FUNC_LSTAT_FOLLOWS_SLASHED_SYMLINK):
2176 Fix typo introduced with 2006-04-02 change. It reversed the sense
2179 2006-05-23 Paul Eggert <eggert@cs.ucla.edu>
2181 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Simplify ac_dA and
2182 ac_dB slightly, to save bytes in the script.
2183 Max out at 50 lines, rather than 96; this is more likely
2184 (though not guaranteed) to avoid obscure 'sed' failures.
2186 2006-05-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2188 * lib/autotest/general.m4 (AT_INIT): UnixWare `tr' may interpret
2189 `tr -d -' as bad option argument. Work around this by deleting
2190 an unrelated character.
2191 Report by Tim Rice <tim@multitalents.net>.
2193 2006-05-22 Paul Eggert <eggert@cs.ucla.edu>,
2194 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>,
2195 Stepan Kasal <kasal@ucw.cz>
2197 * doc/autoconf.texi (Particular Programs): Do not promise that
2198 we always prefer the GNU version of the program, and that we
2199 search according to PATH; both rules can have exceptions.
2200 Update description of AC_PROG_GREP, AC_PROG_EGREP, AC_PROG_FGREP,
2201 AC_PROG_SED. Move descriptions of limitations
2202 to the Limitations of Usual Tools section.
2203 (Limitations of Usual Tools) <sed>: Mention script length
2204 limitations with Solaris /usr/ucb/sed.
2205 <grep>: Fix wording for empty alternative. Mention that -c and
2206 -l should not be combined, and that -E and -F should not be
2209 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2210 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2212 * lib/autoconf/programs.m4 (AC_PROG_SED): Catch script length
2213 limits in Solaris 8 /usr/ucb/sed by testing a long script.
2215 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2217 * doc/autoconf.texi (Defining Symbols): Literal parameter of
2218 AC_DEFINE is now passed to m4_pattern_allow.
2219 * NEWS: Mention that; likewise for AC_SUBST.
2220 * lib/autoconf/general.m4 (AC_DEFINE_TRACE_LITERAL): Pass
2221 the parameter to m4_pattern_allow.
2222 * tests/tools.at: Add a check for that.
2224 2006-05-22 Stepan Kasal <kasal@ucw.cz>
2226 * lib/autoconf/status.m4: Fix typos.
2228 2006-05-21 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2230 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Remove
2231 only the files that this macro generates.
2233 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2235 * doc/autoconf.texi (Limitations of Usual Tools) <sed>: For
2236 the HP-UX sed limitation of 99 commands, labels do not count.
2237 * lib/autoconf/status.m4 (_AC_SED_CMD_LIMIT): Mention that
2239 (_AC_OUTPUT_HEADER): Revert the change from 2006-05-19.
2241 2006-05-21 Paul Eggert <eggert@cs.ucla.edu>
2243 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT):
2244 Import the following fix from coreutils:
2246 2006-01-13 Jim Meyering <jim@meyering.net>
2248 Invoke AC_CHECK_FUNCS(getmntent) unconditionally so that tests of
2249 $ac_cv_func_getmntent (e.g., in gl_LIST_MOUNTED_FILE_SYSTEMS) need
2250 not double-quote uses of that variable, to accommodate the rare
2251 case in which getmntent is available in none of the libraries
2252 checked. This happens at least on FreeBSD 5.0.
2254 2006-05-20 Paul Eggert <eggert@cs.ucla.edu>
2256 * lib/autoconf/general.m4 (AC_CONFIG_AUX_DIRS): Bring back
2257 ac_config_guess, ac_config_sub, and ac_configure, since evidently
2258 some other programs unwisely rely on these undocumented vars.
2259 But put in warning comments about them.
2260 Problem reported by Ralf Wildenhues in
2261 <http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00068.html>.
2262 * NEWS: Document that these variables are intended to go away.
2264 2006-05-20 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2266 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): Require AC_PROG_CXX,
2267 and set the language to C++ (analogous to the equivalent Fortran
2270 * lib/autoconf/c.m4 (AC_PROG_CXX_C_O): New macro.
2271 * doc/autoconf.texi (C++ Compiler): Document it.
2272 * lib/autoconf/fortran.m4 (_AC_PROG_FC_C_O): Adjust comment.
2275 2006-05-19 Paul Eggert <eggert@cs.ucla.edu>
2277 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADER): Fix off-by-one bug
2278 that caused config.status to generate 100-command sed scripts; the
2279 portable limit is 99.
2281 2006-05-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2283 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): Name temporary
2284 variable `ac_d' instead of `d' to avoid infringing namespace.
2285 Report by Ralf Menzel.
2287 2006-05-18 Paul Eggert <eggert@cs.ucla.edu>
2289 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): Don't prepend
2290 $ac_top_build_prefix to $MKDIR_P if it's just 'mkdir -p'.
2291 * tests/tools.at (autoconf: subdirectories): New test, taken from
2292 the corresponding problem report by Ralf Wildenhues in:
2293 http://lists.gnu.org/archive/html/autoconf-patches/2006-05/msg00053.html
2295 * lib/autoconf/functions.m4 (AC_REPLACE_FNMATCH, AC_FUNC_FNMATCH_GNU):
2296 Quote some uses of shell variables if they might suffer unexpected
2297 globbing. This doesn't fix all instances of quoting problems that
2298 I found, just the easy ones that look safe.
2299 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR, _AC_INIT_HELP):
2300 (AC_CONFIG_AUX_DIR, AC_CONFIG_AUX_DIR_DEFAULT, AC_CONFIG_AUX_DIRS):
2301 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST, AC_CANONICAL_TARGET):
2302 (AC_CACHE_LOAD, AC_CACHE_SAVE): Likewise.
2303 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF, _AC_PATH_X_DIRECT): Likewise.
2304 * lib/autoconf/specific.m4 (AC_SYS_LONG_FILE_NAMES): Likewise.
2305 * lib/autoconf/status.m4 (_AC_OUTPUT_LINK, _AC_OUTPUT_SUBDIRS):
2307 * lib/autotest/general.m4 (_AC_INIT_PARSE_ARGS): Likewise.
2308 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Likewise.
2310 2006-05-18 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2312 * bin/autoreconf.in ($help): Reword according to the manual.
2313 Suggested by Olly Betts.
2315 2006-05-17 Olly Betts <olly@survex.com> (tiny change)
2316 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2318 * bin/autoreconf.in: Pass the directory argument to
2319 `require_configure_ac'. Fix comment.
2320 * tests/torture.at (Configuring subdirectories): Expose this.
2321 Reported by Olly Betts.
2323 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2325 * lib/Automake/Configure_ac.pm, lib/Automake/Channels.pm,
2326 lib/Automake/FileUtils.pm, lib/Automake/Struct.pm: Sync from
2327 Automake as follows:
2329 * lib/Autom4te/Configure_ac.pm (find_configure_ac): Use
2330 `$configure_in' instead of `configure.in', to preserve
2331 directory component.
2333 2006-05-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2335 * config/config.guess, config/config.sub, config/texinfo.tex,
2336 doc/make-stds.texi, doc/standards.texi: Sync from upstream.
2338 2006-05-14 Paul Eggert <eggert@cs.ucla.edu>
2340 * lib/autoconf/headers.m4 (AC_HEADER_STDBOOL): Fix overly-picky
2341 test for C99 conformance; (bool) 0.5 is an integer constant
2342 expression, but (bool) -0.5 is not. Problem reported by Fedor
2343 Sergeev in <http://forum.sun.com/jive/thread.jspa?threadID=96202>.
2345 2006-05-13 Paul Eggert <eggert@cs.ucla.edu>
2347 * doc/autoconf.texi (Particular Programs): AC_PROG_MKDIR_P now
2348 sets MKDIR_P, not mkdir_p, to avoid collisions with Automake.
2349 Warn about obsolete install-sh files. Remove stray sentence
2350 fragment and fix cross reference.
2351 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Don't insist on
2352 install -d; this undoes the 2006-05-10 change.
2353 (MKDIR_P): Mark with AN_MAKEVAR.
2354 (AC_PROG_MKDIR_P): Fall back on $ac_install_sh, not $INSTALL, so
2355 that we don't require $INSTALL to be thread-safe. Move comments
2356 out of generated code. Require AC_CONFIG_AUX_DIR_DEFAULT instead
2357 of AC_PROG_INSTALL. Output a message saying that we're checking
2358 mkdir -p. Set MKDIR_P rather than mkdir_p. Do special magic for
2359 MKDIR_P instead of AC_SUBST.
2360 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE, _AC_OUTPUT_CONFIG_STATUS):
2361 Special magic for MKDIR_P, too.
2362 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Remove comment that defeated
2364 * tests/local.at (AT_CHECK_ENV): mkdir_p -> MKDIR_P.
2366 2006-05-11 Paul Eggert <eggert@cs.ucla.edu>
2368 Sync from Automake, as follows:
2370 2006-05-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2371 * config/install-sh: Initialize IFS, so field splitting isn't
2373 * config/mkinstalldirs: Likewise.
2374 * config/missing: Remove superfluous quotes. Replace all uses of
2375 `[' by `test', for consistency, and for..
2376 * config/missing (sed_minuso, sed_output): New variables.
2377 (autom4te, help2man, makeinfo): Use them. Unifies detection of
2378 `-o FILE', `--output FILE', `--output=FILE', stricter regex.
2379 Fixes `missing' to detect `--output' for help2man. Fixes
2380 PR automake/483. Report by Dennis J. Linse.
2381 (autom4te): Document in `missing --help'.
2383 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2385 * NEWS: New macro AC_PROG_MKDIR_P. AS_MKDIR_P is now more robust.
2386 * config/install-sh: Don't use 'path' to talk about file names,
2387 as per GNU coding standards. Close a race condition reported by Ralf
2388 Wildenhues and Stepan Kasal. There is still a race condition
2389 on hosts that predate Posix 1003.1-1992, but we can't help this.
2390 Don't mishandle weird characters like space on pre-Posix hosts.
2391 Invoke mkdir at most once per dir arg on pre-Posix hosts.
2392 * doc/autoconf.texi (Programming in M4sh): Cross-reference to
2393 AC_PROG_MKDIR_P from AS_MKDIR_P.
2394 (Limitations of Usual Tools): Cross-reference to AC_PROG_MKDIR_P
2395 from mkdir. Mention that Autoconf 2.60 install-sh is safe but
2396 earlier editions are not (including Automake 1.8.3).
2397 Do not suggest mkinstalldirs for thread-safety.
2398 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Insist on an 'install'
2399 that understands -d, so that AC_PROG_MKDIR_P can fall back on $INSTALL.
2400 * lib/m4sugar/m4sh.m4 (AS_MKDIR_P): Make it more robust in the
2401 presence of special characters and race conditions.
2402 * tests/local.at (AT_CHECK_ENV): Add mkdir_p to the list of variables
2403 in Autoconf's name space.
2405 2006-05-10 Bruno Haible <bruno@clisp.org>
2406 and Paul Eggert <eggert@cs.ucla.edu>
2408 * lib/autoconf/programs.m4 (AC_PROG_MKDIR_P): New macro, taken
2409 from Automake with minor changes.
2410 * doc/autoconf.texi (Particular Programs): Document AC_PROG_MKDIR_P.
2412 2006-05-10 Paul Eggert <eggert@cs.ucla.edu>
2414 * config/install-sh: Update to Automake CVS version, as follows:
2415 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2416 * lib/install-sh: Simplify the expr implementation of dirname.
2417 2006-04-24 Paul Eggert <eggert@cs.ucla.edu>
2418 * lib/install-sh: Handle --, and diagnose unknown options.
2420 2006-05-09 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2422 * tests/Makefile.am (AUTOTEST): Use `$(MY_AUTOM4TE)' instead of
2423 `./autom4te' to create `./testsuite', since the `all' target
2424 will ensure its presence, but `installcheck' should not create
2425 the uninstalled wrappers.
2427 * tests/torture.at (Unusual Automake input files): Skip if we
2428 detect automake < 1.8.
2430 2006-05-07 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2432 * lib/autoconf/c.m4 (AC_PROG_CC_STDC): If ac_cv_prog_cc_stdc
2433 is set to `no', then that overrides and sets ac_cv_prog_cc_c89
2434 and ac_cv_prog_cc_c99 to `no', for backward compatibility.
2437 2006-05-06 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2439 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Take care not to
2440 munge (multiple) white space and other oddities.
2441 * tests/torture.at (AT_CHECK_AC_ARG_VAR): Make sure to M4-escape
2442 single quotes in variable assignment.
2443 (AC_ARG_VAR, configure invocation): Adjust tests to expose this
2444 and similar failures by adding multiple spaces, tabs, and other
2446 Report and different test suggested by Francesco Romani
2447 <fromani@gmail.com> and Andrew Church <achurch@achurch.org>.
2449 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): When we escape
2450 single quotes, we only need to search for single quotes; this
2451 both simplifies the search pattern, and makes us less
2452 susceptible to `echo' variations for arguments not containing
2454 (_AC_ARG_VAR_VALIDATE): Likewise.
2456 2006-05-04 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2458 * doc/autoconf.texi (Special Shell Variables) <IFS>: Document
2459 `$*' and IFS concatenation issue with traditional shells and
2460 bash-2.04. Report by Seanster@Seanster.com.
2462 2006-05-03 Bruno Haible <bruno@clisp.org>
2464 * doc/autoconf.texi (Limitations of Usual Tools): Identify more
2465 precisely which Mac OS X versions have the od problem.
2467 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2469 * doc/autoconf.texi: Use @option systematically.
2471 2006-05-02 Paul Eggert <eggert@cs.ucla.edu>
2472 and Bruno Haible <bruno@clisp.org>
2474 * doc/autoconf.texi (Limitations of Usual Tools): Add a paragraph
2476 (Integer Overflow): Mention the special case of integer division
2479 2006-05-02 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2481 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Cater for
2482 traditional shells like the Solaris one that do not use the
2483 first IFS character for assembling `$*'.
2484 Prompted by a related report from autoconf_bug@nro.ca.
2486 2006-05-01 Paul Eggert <eggert@cs.ucla.edu>
2487 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2489 * doc/autoconf.texi (Limitations of Builtins, Limitations of Make):
2490 Mention more problems with the -e option.
2492 2006-04-30 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2495 * doc/autoconf.texi (Systemology): Mention the Heirloom Project.
2497 * doc/autoconf.texi (Introduction, Pointers): Use `@/' liberally
2498 in URLs to improve DVI formatted output (requires texinfo 4.6).
2499 (System Services, Systemology, Shellology): Likewise.
2500 (Limitations of Usual Tools): Rewrite Mac OS X example for nicer
2503 * doc/autoconf.texi (Fortran Compiler): Do not use `@ovar' in
2505 (Runtime): Fix macro argument names to match description:
2506 `action-if-found' -> `action-if-true' and similarly.
2507 (Obsolete Macros): Likewise.
2508 * lib/autoconf/general.m4 (_AC_COMPILE_IFELSE): Likewise.
2509 (AC_COMPILE_IFELSE, AC_TRY_COMPILE, _AC_LINK_IFELSE)
2510 (AC_LINK_IFELSE, AC_TRY_LINK, AC_COMPILE_CHECK): Likewise.
2512 2006-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2514 * doc/autoconf.texi (Limitations of Make): Clean up markup.
2517 * doc/autoconf.texi (Portable Shell): Allow wrapped URLs, for
2520 2006-04-28 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2522 * doc/autoconf.texi (Limitations of Builtins): Document FreeBSD
2523 /bin/sh set unsorted output.
2524 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Adjust.
2525 * tests/local.at: Likewise.

2529 * doc/autoconf.texi (Portable C and C++, Varieties of Unportability):
2530 (Integer Overflow, Null Pointers, Buffer Overruns):
2531 (Floating Point Portability, Exiting Portably): New sections.
2532 (Writing Test Programs): Fix some langauge. Recommend exiting
2533 with status 1, not merely nonzero. Clarify exit declaration.
2534 (Run Time): Move C exit status stuff to new Exiting Portably section.
2535 (Systemology): Mention Posix and levenez. Update v7 reference.
2536 (Portable Shell): Mention the Posix shell.
2538 2006-04-25 Stepan Kasal <kasal@ucw.cz>
2540 * bin/autoconf.as (me): Replace by as_me.
2542 2006-04-25 Paul Eggert <eggert@cs.ucla.edu>
2544 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Don't use AS_ERROR,
2545 since as_me isn't set yet.
2547 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2549 Prepare for deprecation of AS_BASENAME and AS_DIRNAME, and fix
2550 a few minor bugs in this area.
2552 * doc/autoconf.texi (Programming in M4sh): Comment out the
2553 documentation of AS_BASENAME, for now.
2554 (Shell Substitutions): Do not use AS_DIRNAME in an example.
2555 (Limitations of Builtins) <basename>: Do not refer to
2557 * bin/autoconf.as (me): Don't use AS_BASENAME.
2558 (dir): Remove the unused variable.
2559 * lib/m4sugar/m4sh.m4 (_AS_DETECT_REQUIRED): Renamed from
2560 AS_DETECT_REQUIRED. All uses changed.
2561 (_AS_DETECT_SUGGESTED): Renamed from AS_DETECT_SUGGESTED.
2563 (_AS_DETECT_BETTER_SHELL): Put ;; at the end of a case.
2564 (AS_BASENAME): Use "basename --" to protect against leading "-".
2565 (_AS_BASENAME_EXPR): Renamed from AS_BASENAME_EXPR. All uses changed.
2566 (_AS_BASENAME_SED): Renamed from AS_BASENAME_SED. All uses changed.
2567 (_AS_BASENAME_PREPARE): Reject implementations that cannot handle "--".
2568 (_AS_DIRNAME_PREPARE): Likewise.
2569 (_AS_DIRNAME_EXPR): Renamed from AS_DIRNAME_EXPR. All uses changed.
2570 (_AS_DIRNAME_SED): Renamed from AS_DIRNAME_SED. All uses changed.
2571 (AS_DIRNAME): Use "dirname --".
2573 2006-04-23 Paul Eggert <eggert@cs.ucla.edu>
2575 * doc/autoconf.texi (Runtime): Renamed from "Run Time". All uses
2576 of "run time" and "run-time" changed to "runtime", for consistency.
2577 * lib/autoconf/fortran.m4: Likewise (in comment).
2578 * lib/autoconf/functions.m4: Likewise.
2579 * lib/autoconf/general.m4: Likewise.
2580 * lib/autoconf/headers.m4: Likewise.
2582 * doc/autoconf.texi (Run Time): Document the exit status situation
2583 with more accuracy and detail.
2585 2006-04-23 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2587 * doc/autoconf.texi (Introduction): The GNU Autoconf Macro
2588 Archive is not officially `GNU' any more. Update URL.
2589 (Defining Directories): Likewise
2590 * lib/autoconf/c.m4 (AC_C_RESTRICT): Update URL.
2592 2006-04-19 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2594 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Remove the leading
2595 newline from the `trap' code to finish `config.log'; the NetBSD
2596 /bin/sh resets the exit status after an empty command, as
2597 documented in doc/autoconf.texi.
2598 Reported by Dalibor Topic <robilad@kaffe.org>.
2600 2006-04-19 Paul Eggert <eggert@cs.ucla.edu>
2602 * doc/autoconf.texi (C Compiler): Clarify AC_C_TYPEOF.
2603 Suggested by Bruno Haible.
2605 2006-04-18 Paul Eggert <eggert@cs.ucla.edu>
2607 * configure.ac (ac_cv_sh_n_works): Don't try to test for it, since
2608 some shells (e.g., Solaris 8 /bin/sh) implement it verrrry slowly.
2609 Instead, just list the shells that we know work.
2610 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Remove 2nd arg. All uses
2611 changed. Be more cautious about the _cv_ variable.
2612 * tests/tools.at (Syntax of the shell scripts): Check the
2613 _cv_ variable once, at first, to avoid an internal autoconf error
2614 when sh -n does not work.
2616 2006-04-17 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2618 * lib/Autom4te/FileUtils.pm: Sync from Automake.
2620 2006-04-16 Paul Eggert <eggert@cs.ucla.edu>
2622 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Don't
2623 use ">&-" since we're only 99.999% sure that this is portable,
2624 and since the MinGW bug is fixed in a different way.
2625 * lib/autotest/general.m4 (AT_INIT): Likewise.
2627 2006-04-16 Stepan Kasal <kasal@ucw.cz>
2629 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Handle --recheck
2630 before opening config.log, to avoid hitting a bug on MinGW.
2632 2006-04-14 Paul Eggert <eggert@cs.ucla.edu>
2634 * lib/autoconf/general.m4 (_AC_INIT_CONFIG_LOG): Close
2635 AS_MESSAGE_LOG_FD before reopening it onto the log file.
2636 This works around a MinGW bug reported by Eric Paire.
2637 Make sure that all writes to the log file append to it,
2638 rather than possibly losing data.
2639 * lib/autotest/general.m4 (AT_INIT): Likewise.
2641 2006-04-14 Stepan Kasal <kasal@ucw.cz>
2643 * lib/Autom4te/FileUtils.pm (find_file): Fix a typo in the
2646 2006-04-13 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2650 * configure.ac (AC_INIT): Bump to 2.59d.
2652 2006-04-12 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2656 * Makefile.maint (news-date-check): Do not require a leading `*'
2657 before the release date in NEWS.
2659 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2660 and Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2662 * lib/autoconf/status.m4 (_AC_OUTPUT_FILE): If the templates for
2663 the instantiated file do not contain the string 'datarootdir'
2664 but contain @datadir@, @docdir@, @infodir@, @localedir@, or
2665 @mandir@, replace the reference '${datarootdir}' by the value.
2666 * tests/torture.at (datarootdir workaround): New test.
2667 * NEWS: Advertise this temporary fixup.
2668 Based on a patch by Bruno Haible, reported and analyzed by
2669 Paul Eggert and Noah Misch.
2671 2006-04-12 Eric Blake <ebb9@byu.net>
2673 * tests/autotest.at (Debugging a failed test): Fix comment.
2675 2006-04-12 Stepan Kasal <kasal@ucw.cz>
2677 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): Simplify the summary of
2678 all the changes since 2006-04-07.
2680 2006-04-11 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2682 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): If `ln -s file1 file2'
2683 succeeded, but `ln -s file dir' failed, take care to remove the
2684 leftover target before the next test, to prevent its spurious
2685 failure; also make sure `ln file dir' works before selecting it.
2686 Thanks to Keith Marshall for pointing this out.
2689 * lib/autotest/general.m4 (AT_INIT): Store quoted variable
2690 assignments in `at_debug_args', so that we put them correctly
2691 in the `run' script.
2692 * tests/autotest.at (Debugging a failed test): Unmark XFAIL.
2693 Reported by Eric Blake.
2695 2006-04-11 Eric Blake <ebb9@byu.net>
2697 * tests/autotest.at (AT_CHECK_AT): Add new argument, to allow
2698 top-level tests after micro-suite has been run. Used in...
2699 (Debugging a successful test, Debugging script and environment),
2700 (Debugging a failed test): ...these new tests. The first of these
2702 * lib/autotest/general.m4 (_AT_CREATE_DEBUGGING_SCRIPT): New
2703 macro, split out from...
2704 (AT_INIT): ...here, so that using -d also generates a run script.
2705 Document that -d inhibits top-level logging.
2706 * doc/autoconf.texi (testsuite Invocation): Document that -d only
2707 inhibits top-level logging; debug scripts are created.
2709 * lib/autotest/general.m4 (_AT_CHECK): Avoid syntax error on empty
2711 * tests/autotest.at (Empty test, Empty check): New test to check it.
2713 * lib/autoconf/c.m4 (AC_C_CONST, AC_C_VOLATILE): Avoid warnings
2716 2006-04-10 Stepan Kasal <kasal@ucw.cz>
2718 * tests/mktests.sh: Use "trap '' 0", not "trap 0". Do not touch
2719 the files if a problem appears. Make the empty *.at files
2720 read-only, too. Proposed by Ralf Wildenhues.
2722 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2724 * config/Makefile.am: Add comment to force updated Makefile.in.
2726 * lib/freeze.mk: Fix typo in comment. Unlike the last, white
2727 space only patch to this file, this patch causes the Makefile.in
2728 files that include freeze.mk to be updated, and thus have a
2729 newer time stamp again, which in turn makes a pristine CVS
2730 checkout have correct time stamps.
2732 * Makefile.maint (cvs-sv): New macro, to be used..
2733 (config.guess-url_prefix, config.sub-url_prefix)
2734 (texinfo.tex-url_prefix, standards.texi-url_prefix): ..here;
2735 point to CVS text checkout of Gnulib files.
2736 (copyright-check): Bump current year.
2737 (announcement): Do not hard-wire `./announce-gen'.
2738 (cvs-update): Propagate failures of `cvs' and `move-if-change'
2740 * Makefile.cfg (executable-update): Use `chmod a+x' instead of
2742 (wget_files): Update config.guess, config.sub, texinfo.tex by
2743 `wget-update', now that their URLs work again.
2745 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2747 * doc/autoconf.texi (Particular Types): Don't use AC_CHECK_TYPE.
2748 Problem noted by Paul D. Smith.
2750 2006-04-10 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2752 * doc/autoconf.texi: Remove unused words from word list.
2753 * .x-sc_prohibit_atoi_atof, .x-sc_space_tab, .x-sc_sun_os_names,
2754 .x-sc_trailing_space: New files.
2756 * doc/standards.texi: Sync from gnulib.
2758 * NEWS, doc/autoconf.texi (AC_LIBOBJ vs LIBOBJS): Mark
2759 `LIBOBJDIR' as experimental.
2761 * lib/m4sugar/m4sh.m4 (_AS_LN_S_PREPARE): MSYS `ln -s' fails
2762 with a target directory; it's internally implemented as `cp'
2763 anyway, but since Autoconf advertises the possibility to use
2764 a target directory when LN_S is `ln -s', we need to find out.
2765 Reported by Rolf Ebert <rolf.ebert.gcc@gmx.de> against MSYS,
2766 analyzed by Keith Marshall <keith.marshall@total.com>.
2770 2006-04-10 Paul Eggert <eggert@cs.ucla.edu>
2772 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Just output
2773 confdefs.h as-is. In general, if it has backslash-newline or the
2774 like, then it doesn't work either to sort or to remove empty
2777 2006-04-09 Stepan Kasal <kasal@ucw.cz>
2779 * tests/Makefile.am (AUTOCONF_FILES): Fix typo in the comment.
2781 2006-04-09 Alexandre Duret-Lutz <adl@gnu.org>
2783 * lib/autom4te.in (Automake-preselections): Preselect
2786 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2788 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Use '\'' for an
2789 apostrophe within a single-quoted string, as this is the usual
2790 tradition and is easier to read than '"'"'. Don't rely on the
2791 shell treating "$/" like '$/'. Use a more-consistent indenting
2794 2006-04-09 Eric Blake <ebb9@byu.net>
2796 * tests/autotest.at (Backquote command substitution),
2797 (Multiline backquote command substitution): Remove mistaken
2798 AT_NO_CMDSUBST from the 2006-03-14 patch, which was meant to be
2800 (Parenthetical command substitution, Multiline parenthetical
2801 command substitution): here.
2803 2006-04-08 Paul Eggert <eggert@cs.ucla.edu>
2805 Import macros from gnulib (often changing their name).
2807 * NEWS: AC_C_TYPE_LONG_DOUBLE is now obsolete.
2808 New macros AC_CHECK_DECLS_ONCE, AC_CHECK_FUNCS_ONCE,

2934 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
2936 * lib/autoconf/general.m4 (_AC_CACHE_DUMP): Fix the detection of
2937 whether `set' quotes correctly: redirect stderr of the tested
2938 `set', and use a subshell, for Ultrix; use `sed' instead of
2939 `grep' for zsh `set' which may write binary output; match only
2940 at the beginning of a line, to avoid false positives.
2941 In order to avoid false positives by unrelated variables with
2942 multiline content, put the dump algorithm in a subshell and
2943 unset all variables containing newlines (except some which are
2944 special to the shell). Warn about cache variables that are

2990 ac_config_<foo>s again, sometimes normalized, sometimes not.
2991 (AC_CONFIG_FILES, AC_CONFIG_HEADERS, AC_CONFIG_LINKS):

2993 (_AC_CONFIG_REGISTER_DEST): Double quote the tags in macros _AC_LIST_TAGS
2994 and_AC_LIST_TAG_COMMANDS; fixes another regression introduced by the

3005 for --help from Cygnus `configure.'
3007 2006-04-06 Paul Eggert <eggert@cs.ucla.edu>

3151 _AC_COMPILER_EXEEXT_WORKS. Move the definition of ac_files and the
3152 initial `rm' of the candidate files...

3238 * bin/autoupdate.in: Handle m4 builtins and m4sugar macros together--
3239 switch all of them on and of when necessary. Fixes the bug when

3937 * lib/autoconf/c.m4 (AC_LANG_CALL(C)): Reformat to match
3938 AC_LANG_FUNC_LINK_TRY. This involves returning the value returned
3939 by the function rather than ignoring it.
3940 (AC_LANG_FUNC_LINK_TRY(C)): Call the function rather than simply
3941 comparing its address. Intel's interprocedural optimization was
3942 outsmarting the old heuristic. Problem reported by

3962 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Balance parentheses.
3963 * lib/autotest/general.m4 (AT_INIT): If the test dir already exists,
3964 make its content writable before removing it. Remove an errorneous
3965 comment from the end, where the logs of the failed tests are copied
3966 to the main log file.
3968 2005-09-27 Stepan Kasal <kasal@ucw.cz>
3970 * tests/semantics.at (AC_C_BIGENDIAN): Pass --force to autoheader,

3975 problems if the testsuite were running too fast.
3977 2005-09-18 Paul Eggert <eggert@cs.ucla.edu>
3979 * lib/autoconf/libs.m4 (_AC_PATH_X_DIRECT): Look for X11/Xlib.h
3980 and XrmInitialize rather than X11/Intrinsic.h and XtMalloc
3981 (which belong to Xt, not X itself). See Debian bug 327655.
3982 * NEWS: Mention this.
3984 2005-09-07 Stepan Kasal <kasal@ucw.cz>

3991 suggested by Ben Elliston. Handle weird characters correctly.
3993 2005-09-06 Stepan Kasal <kasal@ucw.cz>
3995 * lib/autoconf/libs.m4 (AC_SEARCH_LIBS): Merge the two AC_LINK_IFELSE
3996 calls, so that the final expansion of this macro is shorter.
3997 Create the conftest.$ac_ext outside the `for' loop, to speed the run.
3998 Do not use `break' in the argument to AC_LINK_IFELSE, it would skip
3999 the cleanup there. Use AS_VAR_* macros, to be more general.
4000 * tests/semantics.at (AC_SEARCH_LIBS): Check for the cleanup.
4002 * lib/autoconf/general.m4: Use AS_IF where appropriate.
4004 * lib/m4sugar/m4sh.m4 (AS_IF): Use m4_default.

4022 2005-08-26 Stepan Kasal <kasal@ucw.cz>
4024 * doc/autoconf.texi (Programming in M4sh) <AS_TR_CPP>: Fix m4 quoting
4025 in the example. Reported by Bruno Haible.
4026 <AS_TR_SH>: Likewise. Also modify the example to be more convincing:
4027 "if $undefined_var;" succeeds with my shell.
4029 * lib/autoconf/general.m4 (AC_CANONICAL_BUILD, AC_CANONICAL_HOST,
4030 AC_CANONICAL_TARGET): Define by AC_DEFUN, no need to use AC_DEFUN_ONCE;
4031 but change the m4_divert_text to m4_divert_once.
4033 2005-08-25 Paul Eggert <eggert@cs.ucla.edu>
4035 * lib/m4sugar/m4sh.m4 (_AS_VERSION_COMPARE_PREPARE):
4036 Work around bug in Solaris /usr/xpg4/bin/awk.
4037 The bug is present in at least Solaris 8 through 10.
4039 2005-08-24 Stepan Kasal <kasal@ucw.cz>
4041 * lib/autoconf/general.m4 (_AC_CANONICAL_SPLIT): Simplify; rejecting
4042 some evil values and relying on the fact that $* concatenates the
4043 parameters by the first character from IFS.

4050 * doc/autoconf.texi (Configuration Headers): Document AH_HEADER.
4051 Update limitations about when to call AC_CONFIG_HEADERS.
4052 (Configuration Commands): Document that AC_CONFIG_COMMANDS_PRE
4053 parameter can call AC_SUBST, AC_DEFINE, or AC_CONFIG_FOOS; explain
4054 that AC_CONFIG_COMMANDS_PRE and AC_CONFIG_COMMANDS_POST are not
4055 ``Configuration Actions''; fix their index entries.
4057 * lib/autotest/general.m4 (AT_INIT): Process multiple keywords
4058 options correctly. Process N-M as M-N if M is smaller than N.
4059 Process ranges correctly so that N-N will run only N.
4060 Sort and uniquify the tests that will be run. If there is more
4061 than one test, reinsert the banners for the tests.

4067 before passing the macro name to AH_TEMPLATE.

4070 now opens log after option processing; in particular, --version
4071 and --help do not touch config.log.

4088 Prepend to LIBS, not append, in examples.
4090 2005-08-16 Stepan Kasal <kasal@ucw.cz>
4092 When building in place, set srcdir="."; suggested by Tim Van Holder.
4094 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Do this; to recognize
4095 build in place, we need ac_pwd, and thus have to AC_REQUIRE ...
4096 (_AC_INIT_DIRCHECK): ... this macro and AC_DEFUN both of them.
4097 * lib/autoconf/status.m4 (_AC_SRCDIRS): Fix a comment: srcdir="."
4098 does not mean "no --srcdir option".
4100 2005-08-15 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4102 * tests/autoscan.at (autoscan): New file.

4111 * Makefile.maint (GZIP_ENV): When checking the help text of gzip,
4112 add "2>&1"; gzip 1.2.4 prints help on stderr.
4114 2005-07-27 Stepan Kasal <kasal@ucw.cz>
4116 * lib/autotest/general.m4 (_AT_DECIDE_TRACEABLE): The symbol at_reason
4117 was pushdef'ed twice while popped only once. Push it only once.
4118 (_AT_CHECK): Cosmetic changes to the "case $at_status" command.
4120 2005-07-26 Stepan Kasal <kasal@ucw.cz>
4122 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): The message is now

4129 * lib/m4sugar/m4sugar.m4 (m4_strip): Comment fix---change tab to
4130 "<tab>" in comment, so that the point is understandable.
4132 2005-07-25 Stepan Kasal <kasal@ucw.cz>
4134 Rewrite substantial part of lib/autoconf/status.m4.
4135 The main change is that CONFIG_FILES, CONFIG_HEADERS, CONFIG_LINKS,
4136 and CONFIG_COMMANDS are not processed in four separate loops.
4137 Instead, there is one main loop. This alows that the common code
4138 is expanded only once, thus config.status (and configure) is smaller.
4140 The registration mechnism in AC_CONFIG_FILES and cousins also changed;
4141 the AC_LIST_FILES and cousins macros are no longer used.
4143 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES, _AC_OUTPUT_HEADERS,
4144 _AC_OUTPUT_LINKS, _AC_OUTPUT_COMMANDS): Renamed to ...
4145 (_AC_OUTPUT_FILE, _AC_OUTPUT_HEADER, _AC_OUTPUT_LINK,
4146 _AC_OUTPUT_COMMAND): ..., respectively. These macros no longer
4147 contain the initialization, nor the for loop, nor the associated
4148 commands; all these go to ...
4149 (_AC_OUTPUT_MAIN_LOOP): ... this new macro, called from
4150 _AC_OUTPUT_CONFIG_STATUS.
4151 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST, _AC_CONFIG_SPLIT_FILE_IN):
4152 Nuked; the code was merged into _AC_OUTPUT_MAIN_LOOP.
4153 (_AC_OUTPUT_FILE): The creation of the sed script ...
4154 (AC_OUTPUT): ... and the setup of ac_vpsub goes to ...
4155 (_AC_OUTPUT_FILES_PREPARE): ... a new macro, also called from
4156 _AC_OUTPUT_MAIN_LOOP.
4157 (_AC_CONFIG_FILES, _AC_CONFIG_HEADERS, _AC_CONFIG_LINKS,
4158 _AC_CONFIG_COMMANDS): Use ...
4159 (_AC_CONFIG_FOOS): ... this new macro, which uses these ...
4160 (_AC_CONFIG_REGISTER, _AC_CONFIG_REGISTER_DEST): ... new macros.
4161 (_AC_CONFIG_FILE, _AC_CONFIG_HEADER, _AC_CONFIG_LINK,
4162 _AC_CONFIG_COMMAND, _AC_CONFIG_DEPENDENCIES): No longer needed.
4163 (_AC_CONFIG_DEPENDENCY): Update, it uses these ...
4164 (_AC_CONFIG_DEPENDENCY_DEFAULT, _AC_FILE_DEPENDENCY_TRACE_COLON):
4166 (_AC_CONFIG_UNIQUE): Update.
4167 (AC_LIST_FILES, AC_LIST_HEADERS, AC_LIST_LINKS, AC_LIST_COMMANDS):
4168 Replaced by this ...
4169 (_AC_LIST_TAGS): ... new common macro.
4170 (AC_LIST_FILE_COMMANDS, AC_LIST_HEADER_COMMANDS, AC_LIST_LINK_COMMANDS,
4171 AC_LIST_COMMAND_COMMANDS): Replaced by this ...
4172 (_AC_LIST_TAG_COMMANDS): ... new common macro.
4173 (_AC_CONFIG_COMMANDS_INIT): Moved top to the `registration' section;
4174 this didn't belong to the `config commands' section.
4175 (_AC_OUTPUT_COMMANDS_INIT): Don't initialize, m4_ifdef is our friend.
4176 (AC_CONFIG_COMMANDS_PRE, AC_OUTPUT_COMMANDS_PRE,
4177 AC_CONFIG_COMMANDS_POST): Moved to a new section, these didn't belong
4178 to the `config commands' section either.
4179 (AC_CONFIG_SUBDIRS): Don't touch diversion DEFAULTS.
4180 (_AC_LIST_SUBDIRS): Don't initialize, m4_ifdef is our friend.
4182 ... and many changes to the comments nearby.
4184 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): At the end of the day,
4185 set ac_subdirs_all='_AC_LIST_SUBDIRS'.
4186 * tests/torture.at (AC_CONFIG_FILES, HEADERS, LINKS and COMMANDS):
4187 AC_CONFIG_COMMANDS(command:input,...) is no longer allowed.
4188 (#define header templates): The comment at the top of the generated
4189 header now includes the name(s) of the source file(s).
4191 Several unrelated small changes:
4193 * lib/autoconf/general.m4 (AC_CACHE_VAL): Be didactic, quote the first
4194 parameter to AC_DIAGNOSE.
4195 * lib/autoconf/status.m4 (AC_CONFIG_SUBDIRS): Likewise.
4196 (_AC_LINK_FILES_CNT): Don't AU_DEFUN this; it causes confusing messages

4198 (AC_OUTPUT): In the compatibility code, use m4_ifvaln, to be consistent
4200 (AU::AC_OUTPUT): Don't double-quote $2 and $3, the compatibility code

4297 configure_input, top_builddir, srcdir, etc.
4298 * lib/autotest/general.m4 (AT_INIT): Likewise, for

4309 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): Remove the tests for

4370 2005-06-23 Paul Eggert <eggert@cs.ucla.edu>

4391 variable into diagnostic. Make the diagnostic an error, not a warning,
4392 because we really don't support spaces and suchlike in dir names.
4393 (_AC_INIT_SRCDIR): Allow special characters in $ac_unique_file.
4394 Don't worry about backslashes in srcdir; it can't happen now.

4438 * doc/autoconf.texi:
4439 Don't mention Solaris versions so much, if a
4440 problem is common to all extant versions of Solaris. Say "SunOS
4441 4" instead of "SunOS" for SunOS 4.
4442 (awk): Mention more of the limitations of traditional Awk.

4486 -u, since it outputs chatter if the input files are the same.
4487 Problem reported by Ralf Menzel.
4489 2005-06-08 Derek Price <derek@ximbiot.com>
4491 * lib/m4sugar/m4sugar.m4: Undefine include & sinclude rather than
4492 renaming them since they are about to be redefined anyhow.

4496 * doc/autoconf.texi (Redefined M4 Macros): Add index entries for most
4497 redefined M4 macros to this node. Document m4_include & m4_sinclude.

4503 * doc/autoconf.texi (Introduction): Likewise.
4504 Reword to avoid some formatting glitches.

4509 might get inadvertently cut-and-pasted into user code.

4531 2005-06-06 Stepan Kasal <kasal@ucw.cz>
4533 m4_cdr of one-member list was [[]] (one-member list containing an
4534 empty string) instead of [] (an empty list. Callers were skewed to
4535 match this misbehaviour. As a consequence of this:
4536 - m4_foreach([x], [], [foo]) expanded to `foo', while
4537 - the expansion of m4_foreach([x], [[]], [foo]) was empty.
4538 This bug has been fixed:
4540 * lib/m4sugar/m4sugar.m4 (m4_cdr): If only one argument is given,
4541 expand to an empty string; print error msg if called without
4543 (m4_foreach, m4_map, m4_map_sep): Don't expect the previous

4554 * doc/autoconf.texi (Limitations of Usual Tools): Solaris' awk cannot
4555 swallow records with more than 99 fields.
4556 * lib/autotest/general.m4 (AT_INIT): Use the awk builtin `split' to
4557 parse the long line.
4559 2005-06-04 Stepan Kasal <kasal@ucw.cz>
4561 * doc/autoconf.texi (Limitations of Usual Tools): AIX awk cannot

4666 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Simplify the init
4669 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4671 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Don't m4_quote the second
4672 argument to m4_foreach. I guess it was necessary in the past,
4673 but I think it's a no-op now.
4675 2005-05-17 Stepan Kasal <kasal@ucw.cz>
4677 * lib/autoconf/general.m4 (_AC_INIT_HELP): Merge two consecutive
4678 ``cat <<_ACEOF'' commands to one.
4679 (_AC_CANONICAL_SPLIT): Use expr, not ``echo|sed.''
4680 * lib/autoconf/status.m4: On various places, use expr instead of
4682 (_AC_CONFIG_SPLIT, _AC_CONFIG_SPLIT_SOURCE_DEST):
4683 (_AC_CONFIG_SPLIT_FILE_IN): New macros, to factor out common code.
4684 * lib/autotest/general.m4 (AT_INIT): Use expr to get the numbers from
4686 * tests/local.at (AT_CHECK_SHELL_SYNTAX): Use awk to search for
4687 the wrong patterns between ``case'' and ``esac.'' The previous
4688 code had false positives.

4747 2005-05-11 Stepan Kasal <kasal@ucw.cz>
4749 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Make the check
4750 for absolute directory names in one loop.

4752 abbreviations of --version and --debug.
4754 2005-05-10 Paul Eggert <eggert@cs.ucla.edu>
4756 * doc/autoconf.texi (Autoconf Language): Be more precise about
4757 quoting rules. Problems noted by Stepan Kasal.
4758 Also, throughout this document, be more careful about white space.
4759 "blank", "white space", and "space" all have different meanings
4760 and we should be careful to say what we mean.
4762 2005-05-05 Paul Eggert <eggert@cs.ucla.edu>
4764 Fix C++ related problems reported by Werner Lemberg.
4765 * doc/autoconf.texi (C++ Compiler): Mention .cpp extension.

4767 * lib/autoconf/types.m4 (AC_TYPE_SIGNAL): Simplify test, to
4768 avoid problems with C++ and throw.
4769 * tests/compile.at: .cpp, not .cc.
4771 * tests/semantics.at: Prepend LIBOBJDIR, as per 2005-05-02 change.
4773 2005-05-05 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4775 * doc/autoconf.texi (Generic Functions): Typos.
4777 2005-05-02 Gary V. Vaughan <gary@gnu.org>
4779 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Prepend each
4780 object named in LIBOBJS and LTLIBOBJS with the ${LIBOBJDIR}, as
4781 set by latest automake.
4783 2005-05-01 Paul Eggert <eggert@cs.ucla.edu>
4785 * doc/autoconf.texi (Limitations of Usual Tools): "expr '' \| ''"
4786 outputs 0 on GNU/Linux these days.
4788 2005-04-29 Paul Eggert <eggert@cs.ucla.edu>
4790 * doc/autoconf.texi (Autoconf Language): Add more description
4791 about quoting heuristics.
4792 (Limitations of Builtins): Describe "set -" problems.
4794 2005-04-29 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4796 * lib/autotest/general.m4 (AT_KEYWORDS): Separate by space,
4799 * doc/autoconf.texi (External Software): Replace AC_DEFINE_UNQUOTED
4800 by AC_DEFINE; it was a mistake.
4801 From bug reported against libtool by Dalibor Topic <robilad@kaffe.org>.
4803 2005-04-25 Stepan Kasal <kasal@ucw.cz>
4805 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): A tiny optimization.
4807 2005-04-22 Stepan Kasal <kasal@ucw.cz>
4809 * doc/autoconf.texi (External Software): Quadrigraphs are not
4810 processed correctly in AS_HELP_STRING; avoid this in the examples.
4811 * lib/m4sugar/m4sh.m4 (AS_HELP_STRING): Add a FIXME about quadrigraphs.
4812 * lib/m4sugar/m4sugar.m4 (m4_text_wrap): Likewise; and rephrase the
4813 comment and reduce m4_default([foo], []) to [foo].
4814 (m4_strip): Update the explanation.
4816 2005-04-19 Paul Eggert <eggert@cs.ucla.edu>
4818 * lib/autoconf/general.m4 (_AC_INIT_PREPARE, _AC_RUN_IFELSE):
4819 Remove core.conftest.* too; it's generated by Tru64 5.1.
4820 Problem reported by Jennis Pruett.
4821 * lib/autoconf/functions.m4
4822 (AC_FUNC_SETVBUF_REVERSED, AC_FUNC_UTIME_NULL):
4823 Don't bother to remove core files; AC_RUN_IFELSE should do that
4826 2005-04-19 Stepan Kasal <kasal@ucw.cz>
4828 * lib/m4sugar/m4sugar.m4 (m4_bpatsubsts): Add the b- to comment, too.
4830 2005-04-19 Alexandre Duret-Lutz <adl@gnu.org>
4832 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Handle --docdir.
4833 Report from Horst Wente.
4835 2005-04-15 Stepan Kasal <kasal@ucw.cz>

4842 * doc/autoconf.texi (External Software, Package Options): Add
4843 examples showing how to implement --with-* and --enable-* options.
4845 2005-04-13 Paul Eggert <eggert@cs.ucla.edu>
4847 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): Look for configure.ac
4848 as well as configure.in. Problem reported by Gregorio Guidi.
4850 2005-04-10 Paul Eggert <eggert@cs.ucla.edu>
4852 * doc/autoconf.texi (Particular Functions): Use gnulib's current

4863 2005-04-01 Paul Eggert <eggert@cs.ucla.edu>
4865 * lib/autotest/general.m4 (AT_INIT): Don't assume that "date +%s"
4866 fails if %s isn't supported. Problem reported by Ralf Wildenhues.
4868 2005-03-22 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
4870 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS):
4871 Merge `-z option' as well for the benefit of Solaris link flags. Pass
4872 whole-archive (-zallextract, -zdefaultextract) options in the hope of
4873 unique libraries, for the Sun Fortran 95 8.0 compiler. Bug reported
4874 against Libtool by Yury Puhalsky <pooh@cryptopro.ru>.
4876 2005-03-22 Paul Eggert <eggert@cs.ucla.edu>
4878 * NEWS: The configure command now warns you if you attempt to use
4879 a directory whose name contains a special character like space,
4881 * doc/autoconf.texi (Installation Directory Variables): Allow
4882 "," in file names. Do not use \@; it's not a portable regexp.
4883 * bin/Makefile.am (edit): Likewise.
4884 * lib/Makefile.am (edit): Likewise.
4885 * tests/Makefile.am (edit): Likewise.
4886 * tests/semantics.at: Likewise.
4887 * tests/torture.at: Likewise.
4888 * lib/autoconf/general.m4 (AC_ARG_PROGRAM): Likewise.
4889 * lib/autoconf/status.m4 (_AC_SRCDIRS): Likewise.
4890 * doc/autoconf.texi (File System Conventions): Warn about
4891 unportable file names.
4892 * lib/autoconf/general.m4 (_AC_INIT_DIRCHECK): New macro.
4894 (_AC_INIT_SRCDIR): Use ac_pwd rather than invoking pwd.
4895 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Propagate
4896 ac_pwd, and quote srcdir.
4897 * lib/autotest/general.m4 (AT_INIT): Quote file name args.
4899 * doc/autoconf.texi: Fix some systematic formatting problems.
4900 ".)" needs a following @: if not at the end of a sentence, and
4901 similarly for "!)". "etc." should be preceded by a comma.
4902 "n-th" -> "@var{n}th". pdksh is still buggy, so update its date.
4904 2005-03-22 Bruno Haible <bruno@clisp.org>
4906 * doc/autoconf.texi (Input): Mention that AC_CONFIG_AUX_DIR's
4907 argument is often called 'build-aux'.
4909 2005-03-07 Stepan Kasal <kasal@ucw.cz>
4911 * doc/autoconf.texi (Quotation Rule Of Thumb): Mention that the
4912 macro AC_TRY_LINK is obsolete.
4913 (Installation Directory Variables): Change `AC_OUTPUT_FILES' to
4916 2005-02-24 Stepan Kasal <kasal@ucw.cz>
4918 * lib/autoconf/c.m4 (AC_PROG_CC): Be more careful to skip
4919 `/usr/ucb/cc'; use `cl.exe' to distinguish the MS compiler
4920 from a Common Lisp's `cl'.
4921 (AC_PROG_CXX): Behave according to the documentation: don't
4922 search for $ac_tool_prefix$CCC and $CCC, just set CXX=$CCC;
4923 make the variable CCC precious; use `cl.exe', not `cl'.
4925 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4926 Alexandre Duret-Lutz <adl@gnu.org>
4928 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin from
4929 /dev/null, as "configure" shouldn't read stdin, and this insulates
4930 us from problems (e.g., when testing for "cl"). Also, do this
4931 redirection before invoking "hostname" or "uname", and keep the
4932 original input stream available via...
4933 (AS_ORIGINAL_STDIN_FD): ... this new macro.
4934 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE, _AC_LINK_IFELSE): Don't
4935 bother with "</dev/null" since it's now done at the top of
4937 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Likewise.
4938 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4939 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4940 * doc/autoconf.texi (File Descriptor Macros): New section.
4941 (Printing Messages): Mention it.
4942 * tests/base.at (Input/Output): New test.
4944 2005-02-23 Paul Eggert <eggert@cs.ucla.edu>
4946 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): Don't set ECHO_C to
4947 newline if neither \c nor -n work, as that would output two
4948 newlines. Prefer -n to \c. Reported by Stepan Kasal.
4950 2005-02-12 Stepan Kasal <kasal@ucw.cz>
4952 * lib/m4sugar/m4sh.m4 (AS_IF): Define by m4_defun, not m4_define.
4953 This causes that any required macros inside will get before the if.
4954 * doc/autoconf.texi (autom4te.cache): A typo.
4956 2005-02-12 Paul Eggert <eggert@cs.ucla.edu>
4958 Undo previous change, except keep the change to
4959 lib/autoconf/programs.m4 that replaced grep with shell
4960 pattern-matching. This is because net-snmp configure reads stdin.
4961 Reported by Noah Misch.
4963 2005-02-11 Paul Eggert <eggert@cs.ucla.edu>
4965 * lib/autoconf/general.m4 (_AC_INIT_DEFAULTS): Redirect stdin
4966 from /dev/null, as "configure" shouldn't read stdin, and this
4967 insulates us from problems (e.g., when testing for "cl").
4968 Suggested by Alexandre Duret-Lutz. Also, do this redirection
4969 before invoking "hostname" or "uname".
4970 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4971 _AC_LINK_IFELSE): Undo previous change, as it's no longer needed.
4972 * lib/autoconf/c.m4 (AC_PROG_CC, AC_PROG_CXX): Don't bother with
4973 "</dev/null" since it's now done at the top of 'configure'.
4974 * lib/autoconf/fortran.m4 (_AC_PROG_FC): Likewise.
4975 * lib/autoconf/programs.m4 (_AC_PATH_PROG_FLAVOR_GNU): Likewise.
4976 Also, replace grep with shell pattern-matching, to save a process.
4978 2005-02-10 Paul Eggert <eggert@cs.ucla.edu>
4980 * lib/autoconf/general.m4 (_AC_PREPROC_IFELSE, _AC_COMPILE_IFELSE,
4981 _AC_LINK_IFELSE): Redirect stdin to /dev/null, in an attempt to
4982 avoid thinking that Allegro Common Lisp's "cl" command is a C++
4985 2005-02-09 Paul Eggert <eggert@cs.ucla.edu>
4987 * doc/autoconf.texi (Limitations of Usual Tools): Document that
4988 grep -q isn't portable. Improve grep -s explanation.
4989 Problem reported by Dan Manthey.
4991 2005-02-08 Paul Eggert <eggert@cs.ucla.edu>
4993 * doc/autoconf.texi (Special Shell Variables): Clarify
4994 PATH_SEPARATOR wording; fix typo in IFS. Reported by Gary V. Vaughan.
4996 2005-02-07 Paul Eggert <eggert@cs.ucla.edu>
4998 * doc/autoconf.texi: Use @acronym for DJGPP.
4999 Fix some @code's that should have been @env's, and vice versa.
5000 Sort environment variable names.
5001 Mention that shells no longer inherit IFS.
5002 Don't recommend PATH_SEPARATOR=';' so strongly.
5003 Mention that $RANDOM might expand to the empty string.
5004 "symlink" and "soft link" -> "symbolic link".
5005 Improve mktemp description (reported by Bruno Haible).
5007 2005-02-05 Paul Eggert <eggert@cs.ucla.edu>
5009 * tests/foreign.at (Libtool): Don't overquote AT_SETUP arg.
5010 * tests/m4sh.at (AS_DIRNAME, AS_BASENAME, AS_MKDIR_P, AS_HELP_STRING):
5012 * tests/semantics.at (AC_C_BIGENDIAN, AC_PATH_PROG & AC_PATH_PROGS):
5015 2005-02-04 Paul Eggert <eggert@cs.ucla.edu>
5017 * NEWS: Mention AT_COPYRIGHT.
5019 * tests/local.at (AT_CMP): Use diff directly on input files rather
5022 * lib/autoconf/programs.m4 (AC_PROG_SED): Don't look in
5023 /usr/xpg4/bin since that sed dumps core (at least on Solaris 8).
5025 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5026 and Paul Eggert <eggert@cs.ucla.edu>
5028 * tests/autotest.at (Empty test suite): New test.
5029 * tests/torture.at (Substitute and define special characters)
5030 (Substitute a 2000-byte string, Define to a 2000-byte string)
5031 (Substitute a newline, Define a newline): New tests.
5033 2005-02-04 Noah Misch <noah@cs.caltech.edu>
5035 * lib/m4sugar/m4sugar.m4 (m4_re_string, m4_re_word): Revert 2002-03-04.
5036 * tests/local.at (AT_CHECK_M4SUGAR): Add `m4sugar' to keywords.
5037 (AT_CHECK_ENV): Ignore LTLIBOBJS, FC variables, EGREP, FGREP, and SED.
5038 * tests/m4sugar.at (AT_CHECK_M4SUGAR_TEXT, AT_CHECK_M4RE): New macros.
5039 (Standard regular expressions): New test.
5040 (m4_warn, m4_require: circular dependencies, m4_text_wrap): Strip
5041 excess test name quoting.
5042 * tests/semantics.at (AC_CHECK_HEADERS_OLD, AC_CHECK_HEADERS_NEW): Pass
5043 CPPFLAGS to `configure' instead of setting it in `configure'.
5045 * lib/m4sugar/m4sh.m4 (AS_UNAME): Try only /usr/bin/hostinfo, not
5046 any `hostinfo' in $PATH, since hostinfo.exe is a popular file name
5049 * lib/autoconf/fortran.m4 (AC_LANG(Fortran), AC_FC_SRCEXT):
5050 s/FC_SRCEXT/ac_fc_srcext/; s/FCFLAGS_SRCEXT/ac_fcflags_srcext/.
5052 * tests/local.at (AT_CMP): New macro.
5053 (AT_DATA_AUTOCONF): Do not call AC_PROG_GREP.
5054 (AC_SAVE_STATE): Move environment grep...
5055 (AT_CHECK_ENV): to here. Filter out `'$''. Use AT_CMP.
5056 (AT_CONFIG_CMP): New macro.
5057 (AT_CHECK_MACRO): Run `configure' twice with cache and compare results.
5058 * tests/c.at (Extensions): Do not exit early.
5059 * tests/atlocal.in: Inherit $GREP.
5061 * lib/autoconf/c.m4 (_AC_C_STD_TRY): New macro.
5062 (_AC_PROG_CC_C89, _AC_PROG_CC_C99): Use it.
5064 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Update for 2005.
5065 (AC_COPYRIGHT): Factor header comment portion out and move into...
5066 * lib/m4sugar/m4sh.m4 (AS_COPYRIGHT): This.
5067 * lib/autotest/general.at (AT_COPYRIGHT): New macro.
5068 (AT_INIT): Add Autotest copyright notice. Display copyright notices in
5070 * tests/local.at: Add Autoconf test suite copyright notice.
5071 * doc/autoconf.texi (Writing testsuite.at): Document AT_COPYRIGHT.

5078 2005-02-03 Paul Eggert <eggert@cs.ucla.edu>
5080 * lib/m4sugar/m4sugar.m4 (m4_re_escape): Escape ?, ^, \, $ too;
5081 this fixes a bug tickled by the AT_CAPTURE_FILE change noted below.
5083 Try not to generated lines of unlimited length, as POSIX places a
5084 2047-byte limit on line length of portable text files.
5085 * lib/autoconf/general.m4 (AC_SUBST, AC_SUBST_FILE):
5086 Use newline as a separator, not space.

5088 (AT_CAPTURE_FILE): Use space-backslash-newline as a separator, not
5091 2005-02-03 Ralf Wildenhues <Ralf.Wildenhues@gmx.de>
5093 * lib/m4sugar/m4sh.m4 (_AS_SHELL_FN_WORK): Move func_* to
5094 as_func_*. Add test to check whether positional parameters
5095 are restored after function return.
5097 2005-02-02 Paul Eggert <eggert@cs.ucla.edu>
5099 * doc/autoconf.texi (Special Shell Variables): Mention _,
5100 BIN_SH, DUALCASE. Say that variables other than "status" are safe
5101 if they contain a lower-case letter. The DUALCASE problem was
5102 reported by Ralf Wildenhues.
5104 * bin/autoconf.as: Don't exit with status 0 after write failure
5105 with --help or --version.

5144 Simplify the implementation of m4_require (a.k.a. AC_REQUIRE).
5145 Update the long comment explaining it.
5147 m4_require no longer writes an ``is required by'' line to the
5148 execution stack. It contains only one bit of non-redundant
5149 information: that the macro was required, not called. And even
5150 this bit is useless in most situations: have you ever met a macro
5151 which both calls and requires the same macro?
5153 * lib/m4sugar/m4sugar.m4 (_m4_defun_pro): Don't push a diversion...
5154 (_m4_defun_pro_outer): ... only via this macro, for the outermost

5162 * tests/m4sugar.at (m4_require): Expect output without the
5163 ``is required by'' messages.
5165 2005-01-28 Paul Eggert <eggert@cs.ucla.edu>

5201 * doc/autoconf.texi (Shell Substitutions): Fix typo in case statement.
5202 Warn about newline stripping in `` and $(). Update Solaris
5204 (Limitations of Builtins): Use expr "X...", not expr "x...", as
5205 X insulates us from future changes to Posix.
5206 (Limitations of Usual Tools): For AS_DIRNAME, warn about newline

5231 2005-01-05 Alexandre Duret-Lutz <adl@gnu.org>
5233 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Define datarootdir,

5259 (m4_divert_push, m4_divert_pop, _m4_defun_epi): Don't expand the word
5260 stored in _m4_divert_diversion or _m4_divert_dump.
5261 (m4_divert_pop): When the parameter is given, compare the symbolic
5262 name with the last diversion pushed on the stack. Previously, the
5263 current diversion was compared with the numeric value of the
5264 diversion given as the parameter.
5265 (m4_require): If the macro hasn't been expanded yet, call ...
5266 (_m4_require_call): this new macro.

5573 * lib/autoconf/functions.m4 (AC_FUNC_MEMCMP): Use
5574 "char c = '\200';" rather than "char c = 0x80;" as the
5575 latter doesn't conform to the strict C standard due to
5576 overflow on signed char hosts.
5578 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Prefer -qlanglvl=extc89
5579 to -qlanglvl=ansi. We don't want to disable extensions.
5581 2004-11-29 Paul Eggert <eggert@cs.ucla.edu>
5583 * doc/autoconf.texi (Particular Programs): @code{$PATH} -> @env{PATH}.
5584 (Using Autotest, testsuite Scripts, Writing testsuite.at):

5637 2004-11-13 Stepan Kasal <kasal@ucw.cz>
5639 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't check
5640 the $1_found variable, don't test whether the file is executable;
5641 Both things are checked ...
5642 (_AC_PATH_PROG_FEATURE_CHECK): ... here; AS_EXECUTABLE_P replaces
5643 the former ``test -f''.

5658 * doc/autoconf.texi: Standardize spelling of "Posix" (as opposed
5659 to "POSIX" or "@acronym{POSIX}"), and similarly for "DOS
5660 variants", "Unix", and some related minor wording fixups.
5662 (Shellology, Special Shell Variables): Document that the Zsh
5663 problem with NULLCMD was fixed in zsh 3.1.6-dev-18. Thanks

5673 of putenv. Problem reported by Michael Wardle.
5675 2004-09-22 Paul Eggert <eggert@cs.ucla.edu>
5677 * doc/autoconf.texi (auindex): New macro.
5678 (AU_DEFUN): Use it to fix the bug when the index contained AC_AU_DEFUN.
5679 Problem reported by Stepan Kasal.
5681 2004-09-05 Paul Eggert <eggert@cs.ucla.edu>

5685 * lib/autoconf/programs.m4 (AC_PROG_MAKE_SET): Set SHELL=/bin/sh
5687 * lib/autotest/general.m4 (AT_INIT): Don't assume /dev/null is
5688 readable; it's not true in OS/2-emx.
5690 2004-09-04 Paul Eggert <eggert@cs.ucla.edu>
5692 * lib/autoconf/libs.m4 (_AC_PATH_X_XMKMF): If xmkmf returns
5693 "/usr/include", clear ac_x_includes instead of leaving it as "no"
5694 (trivial change). Problem and patch reported by Andrew Church in:
5695 http://lists.gnu.org/archive/html/bug-autoconf/2004-04/msg00016.html
5697 2004-09-03 Paul Eggert <eggert@cs.ucla.edu>

5724 * Makefile.cfg (wget_files): Remove config.guess, config.sub,
5725 texinfo.tex for now (done by hand now).
5726 * Makefile.maint (wget_files, cvs_files):
5727 Remove ansi2knr.c; nobody uses it.
5728 (ansi2knr.c-url_prefix): Remove.
5729 (cvs-update): Fix test for failure. I don't know why it ever
5732 * doc/autoconf.texi: Update URLs, some of which went stale.
5733 Use @uref rather than @href.
5735 * lib/autoconf/general.m4 (_AC_INIT_PARSE_ARGS): Have configure
5736 handle "--" as per POSIX. Suggested by Paul Pogonyshev.
5738 * config/config.guess, config/config.sub, config/elisp-comp,
5739 config/install-sh, config/mkinstalldirs, config/texinfo.tex,
5740 doc/fdl.texi, doc/standards.texi: Sync with master copy.

5750 Use "file name" rather than "filename" or "path",
5751 to be consistent with the terminology of the GNU coding standards.
5753 2004-08-19 Paul Eggert <eggert@cs.ucla.edu>
5755 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C),
5756 AC_C_LONG_DOUBLE): Undo 2004-06-04 change, as it didn't work with
5757 HP-UX 11.23 cc/aCC or Tru64 4.0 cc. Problem reported by Noah Misch in
5758 <http://lists.gnu.org/archive/html/autoconf/2004-07/msg00004.html>.
5760 More fixes to support spaces in the name of the build directory.
5761 This isn't a complete fix but it's an improvement.
5763 * bin/autoconf.as (autom4te_options): New var.
5764 Use it instead of appending to AUTOM4TE, so that we can allow
5765 spaces in the build directory's absolute name.
5766 * bin/autoheader.in ($autoconf): Allow spaces in file names.
5767 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP, _AT_CHECK,
5768 AT_CHECK_NOESCAPE): Likewise.
5769 * tests/wrapper.as (testdir, AUTOM4TE_CFG, autom4te_perllibdir,
5770 main program): Likewise.
5772 2004-08-18 Paul Eggert <eggert@cs.ucla.edu>

5781 and isnan. From a suggestion by Kevin Ryde.
5783 * lib/Autom4te/General.pm (END): Return correct exit status even
5784 if unlink succeeds and sets $?. Needed with Solaris 8's perl 5.00503.
5786 2004-08-09 Paul Eggert <eggert@cs.ucla.edu>
5788 * tests/torture.at (Deep Package): Use configure.in, not configure.ac,
5789 for compatibility with Automake 1.4. Reported by J C Fitzgerald in
5790 <http://lists.gnu.org/archive/html/bug-autoconf/2003-08/msg00051.html>.
5792 2004-08-04 Alexandre Duret-Lutz <adl@gnu.org>
5794 * lib/autoconf/general.m4 (AC_REQUIRE_AUX_FILE): New empty macro.
5795 (AC_CANONICAL_BUILD): Call it to require config.sub and config.guess.
5796 * lib/autoconf/programs.m4 (AC_PROG_INSTALL): Likewise for install-sh.
5797 * doc/autoconf.texi (Input): Document AC_REQUIRE_AUX_FILE.
5798 * lib/autom4te.in (Automake-preselections): Preselect
5799 AC_REQUIRE_AUX_FILE. Automake 1.10 will trace it.
5801 2004-08-02 Alexandre Duret-Lutz <adl@gnu.org>
5803 * lib/autom4te.in (Automake-preselections): Preselect
5804 AC_CANONICAL_BUILD and AC_CANONICAL_TARGET. Automake 1.9.1 will
5807 2004-07-29 Paul Eggert <eggert@cs.ucla.edu>

5811 * doc/autoconf.texi (Shellology): Mention BIN_SH.
5812 Document problem with "`""`" in pdksh POSIX mode.
5814 2004-07-27 Paul Eggert <eggert@cs.ucla.edu>
5816 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): Use "set -o posix"
5817 with pdksh, too. Problem reported by Patrick Welche via
5819 * doc/autoconf.texi (Shellology): Note that set -o posix is
5820 useful for pkdsh, too.
5822 2004-06-24 Paul Eggert <eggert@cs.ucla.edu>
5824 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Require
5825 _AS_UNSET_PREPARE, so that we can use $as_unset directly.
5826 Don't fail if ENV or BASH_ENV is readonly.
5827 (AS_SHELL_SANITIZE): Don't fail if ENV, MAIL, MAILPATH, LC_ALL,
5828 etc. are read only. Problem reported by Ludovic Courtes.
5830 2004-06-23 Noah Misch <noah@cs.caltech.edu>
5832 * lib/m4sugar/m4sh.m4 (_AS_BOURNE_COMPATIBLE): If the shell is
5833 zsh, disable GLOB_SUBST to avoid backslash handling problems.
5836 2004-06-04 Paul Eggert <eggert@cs.ucla.edu>
5838 * doc/autoconf.texi (File System Conventions): Warn about
5839 names like "aux". Problem reported by Eric Blake.
5841 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY (C)): Use division
5842 by zero instead of array size, so that we can use any arithmetic
5843 constant expression (instead of requiring an integer constant
5844 expression). This allows us to test expressions like DBL_MAX <
5845 LDBL_MAX, which didn't conform to the C standard using the old
5847 (AC_C_LONG_DOUBLE): Put back in the tests for LDBL_MAX and LDBL_EPSILON,
5848 now that we can do floating-point tests at compile time.
5850 2004-06-02 Paul Eggert <eggert@cs.ucla.edu>
5852 * lib/autoconf/c.m4 (AC_C_LONG_DOUBLE): Don't check LDBL_MAX
5853 and LDBL_EPSILON, as the resulting expression isn't an
5854 integer constant expression and violates the C standard.
5855 Problem reported by Nelson H. F. Beebe. Also, check
5856 for "L" suffix, and check that long double doesn't have
5857 worse range or precision than double, that mixed-mode
5858 arithmetic doesn't generate a diagnostic, that double
5859 constants fit in long double.
5861 2004-06-03 Kevin Ryde <user42@zip.com.au>
5863 * doc/autoconf.texi (Function Portability): Add notes on free(NULL),
5864 malloc(0) and realloc(NULL,size).
5866 * doc/autoconf.texi (Shell Substitutions): Spelling error reported by
5869 2004-05-31 Paul Eggert <eggert@cs.ucla.edu>
5871 * lib/autoconf/headers.m4 (HAVE_STDBOOL_H): Detect _Bool bug
5872 in HP aC++/ANSI C B3910B A.05.55 [Dec 04 2003]. Problem reported
5875 2004-05-26 Paul Eggert <eggert@cs.ucla.edu>
5877 * doc/autoconf.texi (Limitations of Builtins): Mention that ! COMMAND
5878 can be rewritten using if-then-else. Suggested by Bruno Haible.
5880 2004-05-25 Paul Eggert <eggert@cs.ucla.edu>
5882 * doc/autoconf.texi (testsuite Scripts): Fix typo.
5883 Problem reported by Stepan Kasal.
5885 2004-05-24 Paul Eggert <eggert@cs.ucla.edu>
5887 * tests/Makefile.am (autoconfdir): Fix to match comment (trivial
5888 change). Patch reported by Ralf Wildenhues in
5889 <http://mail.gnu.org/archive/html/bug-autoconf/2004-05/msg00092.html>.
5891 * lib/autoconf/functions.m4 (AC_FUNC_MBRTOWC): Don't assume that a
5892 function F exists if the compiler and linker let you compile an
5893 expression like (F != 0). Recent versions of GCC optimize away
5894 the reference to F in that case, since every function address must
5895 be nonzero, so the link succeeds even if F does not exist.
5896 Problem reported by Manu in
5897 <http://mail.gnu.org/archive/html/bug-gnu-utils/2004-05/msg00060.html>.
5899 * doc/autoconf.texi (Systemology): Standardize on the spelling of
5900 "Unix". Many uses changed.
5901 (Limitations of Builtins): Explain better why the ! command isn't
5904 2004-05-22 Alexandre Duret-Lutz <adl@gnu.org>

5907 LT_SUPPORTED_TAG in lieu of AC_LIBTOOL_TAGS.
5909 2004-05-19 Kevin Ryde <user42@zip.com.au>
5911 * doc/autoconf.texi (Function Portability): Add strerror_r, cross
5912 referencing AC_FUNC_STRERROR_R.
5914 * doc/autoconf.texi (Particular Functions): In AC_FUNC_CLOSEDIR_VOID,
5915 note pessimistic assumption when cross compiling.
5917 2004-05-16 Paul Eggert <eggert@cs.ucla.edu>
5919 * doc/autoconf.texi (Limitations of Make): Note that BSD make
5920 (until 2004) invoked subcommands with sh -e, contra POSIX.
5921 Reported by Kevin Ryde.
5923 2004-05-10 Eric Sunshine <sunshine@sunshineco.com>
5925 * programs.m4 (_AC_PROG_GREP): Fixed bug where PATH argument handed to
5926 _AC_PATH_PROG_FEATURE_CHECK contained leading whitespace (i.e.
5927 " $PATH:/usr/xpg4/bin"). This resulted in bogus tests, such as
5928 `test -f " /usr/bin/grep"', which _always_ failed.
5929 (AC_PROG_SED): Ditto bogus PATH fix.
5930 * autoconf.texi (AC_PROG_GREP): Properly document that this macro
5931 requires that grep correctly supports _multiple_ `-e' options, rather
5932 than stating only that grep should accept `-e'.
5934 2004-05-03 Paul Eggert <eggert@cs.ucla.edu>
5936 Port to C99, which requires that 'exit' be declared.
5938 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Use AC_INCLUDES_DEFAULT
5939 to ensure that stdlib.h is included.
5940 * lib/autoconf/functions.m4 (_AC_LIBOBJ_ALLOCA, AC_FUNC_SETPGRP,
5941 AC_FUNC_STRTOD, AC_FUNC_SETVBUF_REVERSED, AC_FUNC_FORK, _AC_FUNC_FORK,
5942 _AC_FUNC_VFORK, AC_FUNC_WAIT3): Likewise.
5943 * lib/autoconf/specific.m4 (AC_SYS_RESTARTABLE_SYSCALLS): Likewise.
5944 * lib/autoconf/types.m4 (AC_TYPE_GETGROUPS): Likewise.
5945 * lib/autoconf/headers.m4 (AC_HEADER_STDC): Include <stdlib.h>
5946 when using 'exit' in a test; C99 requires that 'exit' be declared.
5948 2004-05-02 Paul Eggert <eggert@cs.ucla.edu>
5950 * doc/autoconf.texi (Particular Programs): AC_PROG_GREP
5951 now prefers 'grep' implementations that accept -e.
5952 (Limitations of Usual Tools): Describe problems of traditional
5953 egrep and fgrep with long input lines, and of traditional grep
5955 * lib/autoconf/programs.m4 (AC_PROG_GREP): Check for -e, too.
5956 (_AC_PROG_GREP): Assume 3rd arg is properly quoted for the shell.
5957 All callers changed. Append /usr/xpg4/bin to the PATH, for
5959 (_AC_FEATURE_CHECK_LENGTH): Discard stderr, so we don't bother
5960 the user with complaints about multiple -e options.
5961 * tests/local.at (AC_STATE_SAVE): Use $GREP, not grep.
5962 Define it with AC_PROG_GREP.
5963 * configure.ac (AC_PROG_GREP): Add.
5964 * lib/freeze.mk (GREP): New macro.
5966 2004-05-02 Eric Sunshine <sunshine@sunshineco.com>
5968 * lib/m4sugar/m4sh.m4 (_AS_DETECT_BETTER_SHELL): Consult $SHELL as
5969 a possible candidate only after all others fail, rather than
5970 consulting it first. This improves backward compatibility by
5971 better reflecting the way shell selection occurred in previous
5972 versions of Autoconf, and should help to avoid triggering latent
5973 problems in other packages, such as the one in Automake where zsh
5974 is not handled robustly:
5975 http://mail.gnu.org/archive/html/automake/2004-04/msg00095.html
5976 Although it is not Autoconf's responsibility to work around
5977 problems in Automake, it nevertheless makes sense to avoid
5978 introducing unnecessary incompatibilites.
5980 2004-04-22 Albert Chin-A-Young <china@thewrittenword.com>,
5981 Gary V. Vaughan <gary@gnu.org>
5983 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Don't guess
5984 how deeply nested we are when a suitable tool is found, set the
5985 ac_path_TOOL_found flag.
5986 (_AC_PATH_PROG_FEATURE_CHECK): Encapsulate knowledge of how deeply
5987 nested we are in this macro. Break out of all 3 nested loops if
5988 ac_path_TOOL_found is set.
5990 2004-04-21 Gary V. Vaughan <gary@gnu.org>
5992 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Break out
5993 of the _AS_PATH_WALK loop too if GNU flavor is found.
5995 2004-04-21 Alexandre Duret-Lutz <adl@gnu.org>
5997 * doc/autoconf.texi (Limitations of Make): Update documentation
5998 for `$<'. New entry `Long lines', based on a report from Simon
5999 Josefsson. Augment the documentation for SHELL = @SHELL@ with a
6000 paragraph about DJGPP, based on a mail from Richard Dawe.
6002 2004-04-20 Paul Eggert <eggert@twinsun.com>
6004 * tests/c.at (C keywords): Don't assume that GCC supports
6005 "restrict" and "inline", as sufficiently-old GCC versions do not
6006 (also, GCC configured to be in pedantic C89 mode does not).
6007 Problem reported by Sumit Pandya in:
6008 http://mail.gnu.org/archive/html/autoconf/2004-04/msg00092.html
6010 * lib/autoconf/c.m4 (_AC_PROG_CC_G, _AC_PROG_CXX_G): Don't
6011 consider -g to work if it generates warnings when plain compiles
6012 don't. Problem reported by Braden McDaniel in:
6013 http://mail.gnu.org/archive/html/autoconf-patches/2003-07/msg00014.html
6015 * doc/autoconf.texi (Slashes): New section, to document a problem
6016 reported by Jim Meyering in:
6017 http://mail.gnu.org/archive/html/bug-coreutils/2004-02/msg00060.html
6019 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Remove potential
6020 linker output files before linking, to work around IRIX 6 linker bug.
6021 Problem reported by Rainer Orth in:
6022 http://mail.gnu.org/archive/html/autoconf-patches/2004-02/msg00007.html
6024 2004-04-20 Gary V. Vaughan <gary@gnu.org>
6026 * lib/autoconf/programs.m4 (_AC_FEATURE_CHECK_LENGTH): Make the
6027 best tool so far counter rely on the tool path variable name to
6028 avoid checks for one tool being affected by the results of running
6029 the length check on a previous tool.
6031 * lib/autoconf/programs.m4 (_AC_PROG_GREP): Take an additional

6169 AC_SUBST provides no portable way to escape literal newlines.
6171 * lib/autoconf/fortran.m4 (_AC_FC_LIBRARY_LDFLAGS): Ignore all
6172 flags of the form -lcrt*.o, not just -lcrt[01].o and -lcrtbegin.o.
6173 Darwin uses -lcrt2.o and there's little point to cataloging all

6250 * lib/autoconf/general.m4 (_AC_INIT_COPYRIGHT): Add 1992 thorugh
6251 2003 (except 1997) to the list of copyright years. This undoes
6252 the 2003-05-22 change, which removed the older years from the list.
6253 * lib/autoconf/status.m4 (AC_OUTPUT): Update copyright date to 2004.

6266 _AC_PROG_GREP, and AC_PROG_SED.

6299 * doc/autoconf.texi (Default Includes): Include <stdint.h> even if
6300 HAVE_INTTYPES_H is defined. This is needed on Tru64 5.1b with
6301 Compac C V6.5-207 (dtk), which defines uintmax_t in <stdint.h> but
6302 not <inttypes.h>. Problem reported by Tim Mooney in

6304 * lib/autoconf/headers.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS):
6307 * lib/autoconf/programs.m4 (AC_PROG_SED): Use diff, not sed;
6308 otherwise "make check" fails because it forbids cmp (I guess
6309 because cmp treats files as binary on DOS-like systems).

6324 * lib/autoconf/c.m4 (_AC_PROG_CC_STDC): Try -std, not -std1, since
6325 -std1 disables some useful extensions on Tru64. Problem reported

6331 * doc/autoconf.texi (Programming in M4sh): Document that
6332 AS_MKDIR_P succeeds if the destination is a symbolic link
6333 to an existing directory.
6334 (Limitations of Usual Tools): Note that mkdir -p might not
6335 succeed on symlinks to directories.

6355 * lib/autoconf/general.m4: Fix bug: AC_CHECK_SIZEOF evokes a warning
6356 with `autoconf -Wall,error'. Bug reported by Eric Blake in:
6357 http://mail.gnu.org/archive/html/autoconf-patches/2004-01/msg00000.html
6358 (_AC_COMPUTE_INT_COMPILE): Invoke _AC_COMPILE_IFELSE, not
6359 AC_COMPILE_IFELSE, since we now assume our caller invokes
6360 AC_LANG_COMPILER_REQUIRE, for symmetry with _AC_COMPUTE_INT_RUN.
6361 (_AC_COMPUTE_INT_RUN): Likewise, for _AC_RUN_IFELSE instead
6362 of AC_RUN_IFELSE; this avoids the warning mentioned above.
6363 (_AC_COMPUTE_INT): Invoke AC_LANG_COMPILER_REQUIRE.
6365 2004-01-07 Paul Eggert <eggert@twinsun.com>
6367 * lib/autoconf/general.m4 (_AC_LIBOBJS_NORMALIZE): Avoid \$ inside
6368 `"'...'"`, as it's confusing (and I suspect it may not work on
6369 some platforms). The code was incorrect anyway, as it assumed
6370 that \$ evaluated to itself in that context. Reported by
6371 Alexandre Duret-Lutz.
6373 2004-01-07 Alexandre Duret-Lutz <adl@gnu.org>
6375 * lib/autom4te.in (Automake-preselections): Preselect AC_LIBTOOL_TAGS

6405 Bug reported by David Relson in
6406 <http://mail.gnu.org/archive/html/autoconf/2004-01/msg00011.html>.
6408 * Makefile.am (autom4te-update):
6409 Replace "rm -rf" and "rm -fr" with "rm -f -r", as POSIX requires.

6425 * doc/autoconf.texi (Limitations of Usual Tools): Mention that cc
6426 -c -o might not work. From a suggestion by Kevin Ryde.
6427 (C Compiler, Generating Sources, Limitations
6428 of Usual Tools, Limitations of Make, Making testsuite Scripts):
6429 Don't put '-o' after non-options, as POSIX doesn't allow this.
6430 Mention that cc's name might be gcc or c89 or whatever.
6432 2004-01-04 Kevin Ryde <user42@zip.com.au>

6441 2003-12-27 Alexandre Duret-Lutz <adl@gnu.org>
6443 * doc/autoconf.texi (Limitations of Make) <Automatic rule rewriting>:
6444 Documents OSF1/Tru64 make behavior. Replace `VPATH = ../src' by
6445 `VPATH = ../pkg/src' in examples to make the OSF1/Tru64 make
6446 explanation clearer.

6457 * tests/atlocal.in: Store the result here.

6460 of explicitly testing.

6727 Problems reported by Eric Sunshine.
6729 2003-10-08 Steven G. Johnson <stevenj@alum.mit.edu>
6731 * lib/autoconf/fortran.m4 (_AC_PROG_FC_V_OUTPUT): Omit quoted
6732 -mGLOB_options_string stuff for Intel ifc, which can cause
6733 _AC_FC_LIBRARY_LDFLAGS to fail. Use (faster) case for
6734 pattern-matching instead of grep.

6754 2003-10-04 Steven G. Johnson <stevenj@ab-initio.mit.edu>
6756 * lib/autoconf/fortran.m4 (_AC_PROG_FC_G): Use language-specific
6757 cache variable instead of $G77 to decide whether to include -O2,
6758 since $G77 is specific to Fortran 77.
6760 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6762 * lib/autoconf/fortran.m4 (AC_FC_FREEFORM): Support Absoft "-f
6763 free" flag. Re-order flags tested into rough order of popularity.
6765 2003-10-03 Steven G. Johnson <stevenj@alum.mit.edu>
6767 * lib/autoconf/fortran.m4 (AC_PROG_FC): Reverse the order of the
6768 arguments so that it can be used with syntax identical to

6770 remove/deprecate the DIALECT optional argument in the future if it
6772 (AC_FC_FREEFORM): Exit 77 upon failure to fix test suite for

6836 Problem reported by Lars J. Aas in
6837 <http://mail.gnu.org/archive/html/autoconf/2003-07/msg00042.html>.
6838 (_AS_MKDIR_P_PREPARE): Change "rm -fr ./-p" to the more-conservative
6839 "test -d ./-p && rmdir ./-p". Suggested by Andreas Schwab in:

6842 2003-09-26 Akim Demaille <akim@epita.fr>
6844 * lib/autoconf/status.m4 (_AC_OUTPUT_COMMANDS): Make sure the
6845 directory for AC_CONFIG_COMMANDS' first argument exists.
6846 This makes valid the invocation of _AC_SRCPATH that follows.
6847 Reported by Eric Sunshine.
6848 * doc/autoconf.texi (Configuration Commands): Adjust.
6850 2003-09-26 Akim Demaille <akim@epita.fr>

6871 The test suite are sometimes assigning timings incorrectly.
6872 Reported by Henk Krus.
6873 Diagnosed by Nicolas Joly.
6875 * lib/autotest/general.m4 (AT_CLEANUP): Rename AT_help as
6877 Instead of making AT_help a sequence of assignments to grow
6878 $at_help_all, just make AT_help_all be the growing contents of
6879 $at_help_all, and make a single assignment in...
6881 (at_times_skip): Flip the meaning and rename as...
6883 (AT_INIT): When summarizing the test that ran, remove
6884 $at_times_file after use, and check it is present before trying to

6891 * bin/Makefile.am (edit): Handle '@configure_input@'.
6892 (autoconf, autoheader, autom4te, autoreconf, autoscan, autoupdate)
6893 (ifnames): chmod -w.
6894 * tests/wrapper.as (AUTOCONF, AUTOM4TE, ): Point to tests/
6895 executables, not bin/ executables! Otherwise all the magic needed
6896 to find non installed files is turned off. This caused a failure
6897 of test 40 and 41 that ran aclocal 1.8 which in turn ran autom4te
6898 as found in its environment (sent by tests/autoreconf): pointing
6899 to bin/autom4te that could not find its files.
6900 * tests/mktests.sh: Force the replacement of generated files, for
6901 the sake of "mv" program that are interactive when overwriting a
6903 * config/install-sh: Upgrade from CVS Automake.
6905 2003-09-23 Paul Eggert <eggert@twinsun.com>

6948 * tests/mktests.sh (au_exclude_egrep): Make it harder to be
6949 willing to edit the output files.
6951 2003-09-10 Akim Demaille <akim@epita.fr>

6994 * tests/mktests.sh (ac_exclude_list): Add AC_FC_FUNC.
6996 2003-09-02 Steven G. Johnson <stevenj@alum.mit.edu>
6998 Add support for newer Fortran dialects. The F77 interface is
6999 unchanged, and continues to support Fortran 77. New FC macros
7000 correspond to all the old F77 macros, with output variables FC,
7001 FCFLAGS, and FCLIBS. AC_PROG_FC defaults to picking the newest
7002 available dialect, but older dialects can be specified. There are
7003 new macros AC_FC_SRCEXT to set the source extension, and
7004 AC_FC_FREEFORM to accept free-form source files.
7006 * lib/autoconf/c.m4 (_AC_LANG_PREFIX(C), _AC_LANG_PREFIX(C++)):

7130 2003-08-21 Akim Demaille <akim@epita.fr>
7132 First stab at preserving warnings between calls to autom4te,
7133 including when the cache is used.
7135 There are still several issues: (i) there are too many runs of m4
7136 (one for include, one for warnings, and some more), (ii) warnings
7137 spreading on several lines are not handled gracefully, (iii) the
7138 code meant to have the call stack display for errors does not work
7139 (its handling should move from m4 to autom4te).
7141 * bin/autom4te.in Autom4te::Channels, Autom4te::ChannelDefs):
7143 (@preselect): Add m4_warn.
7144 ($exit_status): Remove, use $exit_code.
7145 ($help): Use Autom4te::ChannelDefs::usage.
7146 (&handle_m4): No longer define the m4_warnings.
7147 At each run, extract and report the warnings.
7148 Always cache the result, including if the exit status is on
7149 failure, since if nothing changes, we should result in the same
7150 failure, hence we can use the cache.

7152 (_m4_warning_error_ifelse, __m4_warning_error_ifelse, _m4_warn):
7154 (m4_warn): Redefine as a do-nothing: it is its invocation that
7155 matters, as warnings are now reported via traces.
7156 * lib/autoconf/general.m4 (AC_DIAGNOSE): Don't make it a copy of
7157 the contents of m4_warn: make it _call_ m4_warn, so that tracing
7158 the latter reveals calls to the former.
7162 * tests/m4sugar.at (m4@&t@_warn): Use existing warning categories.

7191 Reported by Alexandre Duret-Lutz.

7195 * bin/autoupdate.in, bin/autoheader.in, bin/autoreconf.in,
7196 * bin/autom4te: Adjust.
7197 In particular, be Autoconf tools are really silent when properly
7198 working, bind the verbosity of the 'note' channel to $verbose.
7199 * lib/Autom4te/General.pm (&find_file, &mtime, &update_file)

7263 shorter column three. Add DESCRIPTION to log file content.

7323 * lib/autotest/general.m4 (AT_INIT): Report a single config.log,
7324 not all of them. This fixes 1. the fact that when testing
7325 Autoconf there are many many config.log, 2. the incorrect use of
7326 top_srcdir to find config.log.
7327 Don't mix the detailed output of failed test with the summary of
7328 failures. Rather, append detailed log afterwards.

7445 Paul Eggert <eggert@twinsun.com>
7447 * lib/autoconf/c.m4 (_AC_PROG_CXX_EXIT_DECLARATION):
7448 Remove `#include <stdlib.h>' from the list; we should never
7449 make confdefs.h include <stdlib.h> or <cstdlib>, because the
7450 resulting namespace pollution would cause other tests to fail.
7451 Configure scripts run with some older versions of g++ and HP's
7452 aCC would fail due to such an #include. Problems reported by
7453 Matthew Mueller in <http://bugs.debian.org/120704> and by
7455 <http://mail.gnu.org/archive/html/autoconf/2003-05/msg00063.html>.
7456 In the test, use the test declaration before including <stdlib.h>,

7466 Overhaul Autotest's logging: generate separate log files
7467 in testsuite.dir/NNN/testsuite.log, and append them to
7468 testsuite.log instead of re-running the test verbosely.
7470 * lib/autotest/general.m4 (AT_INIT): Use a single redirected
7471 file descriptor, write 0 to at_status_file instead of setting
7472 at_status=0, initialize some new variables (at_status_file,
7473 at_group_log, at_suite_log, at_tee_pipe). Remove the cruft
7474 to rerun the tests, instead append the at_group_log to the
7475 at_suite_log when a test fails.
7476 (AT_SETUP): pipe the test case's output into at_tee_pipe,
7477 with the AS_MESSAGE_LOG_FD redirected to stdout.
7478 (AT_CLEANUP): save the output status in $at_status_file
7479 and restore it, redirect the AS_MESSAGE_LOG_FD back to
7481 (AT_CHECK): since tests are run with a redirected stdout,
7482 and used to be re-run in verbose mode, turn some $at_verbose
7483 into echo, and don't redirect the output of testing stdout
7486 * lib/autotest/autoconf.texi (testsuite Scripts): Update

7607 2003-05-06 Akim Demaille <akim@epita.fr>
7609 Don't try to be smart with aclocal 1.8+ because (i) aclocal no
7610 longer updates aclocal.m4 if useless, (ii) if a file m4_included
7611 by aclocal.m4 is changed it might require the importing of another
7612 m4 extension file, i.e., aclocal must be run.
7614 * bin/autoreconf.in (&run_aclocal, $aclocal_supports_force): New.
7615 (&parse_args): Use --force with aclocal if required and supported.

7633 (AT_CLEANUP): Add `;' to end of at_help_all.
7634 (AT_INIT): Allow --keywords to be specified more than once. When
7635 grepping $at_help_all for keywords, use the field and keyword

7732 HELP_TUNING,HELP_OTHER,HELP_END,PREPARE_TESTS,TESTS_END): Define and
7733 use new diversions in preparation for accepting new arguments and
7734 allowing scripting around tests.
7735 (OPTIONS,TAIL): Remove these diversions to make way for the ones above.
7737 2003-03-26 Derek Price <derek@ximbiot.com>

7788 an old Automake change. Discuss NetBSD, FreeBSD, OpenBSD, and
7789 Tru64 make in the "target lookup" section.
7790 (Automake): Automake 1.5+ no longer requires special tools to be
7791 present on the developer's host.
7793 2003-02-26 Richard Dawe <rich@phekda.freeserve.co.uk>
7795 * bin/autoheader.in (BEGIN): For DJGPP SHELL may not be set
7796 to a shell that can handle redirection or quoting correctly.
7797 Override SHELL with the shell detected by configure.
7798 Use of $^O suggested by Tim van Holder.
7799 * bin/autom4te.in (BEGIN): Likewise.
7800 * bin/autoreconf.in (BEGIN): Likewise.
7801 * bin/autoscan.in (BEGIN): Likewise.

7831 * doc/autoconf.texi (Shell Substitutions): test -n -> test -z,
7832 to fix a mismatch between example and discussion.
7834 2003-02-24 Kevin Ryde <user42@zip.com.au>
7836 * doc/autoconf.texi (Limitations of Builtins): Add notes on printf
7837 format starting with "-".
7839 2003-02-20 Alexandre Duret-Lutz <adl@gnu.org>

7846 * lib/autoconf/headers.m4 (_AC_CHECK_HEADER_MONGREL): When
7847 compiler says yeah, but preproc says nope, compiler is right.
7848 Conversely, prompt the reader to send a bug report to the
7849 maintainers of the package, not of Autoconf.
7851 2003-02-20 Klee Dienes <kdienes@apple.com>
7853 * bin/autoreconf.in (autoreconf_current_directory): Properly
7854 handle an empty aclocal.m4.

7862 2002-12-23 Paul Eggert <eggert@twinsun.com>
7864 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Define $1 to an
7865 innocuous variant befor including <limits.h> or <assert.h>. This
7866 works around a bug reported by Albert Chin: HP-UX 11i
7867 (and earlier versions) have a <limits.h> that declares
7868 gettimeofday and many other functions.
7870 2002-12-03 Paul Eggert <eggert@twinsun.com>
7874 * NEWS, configure.ac: Update version.
7876 * doc/fdl.texi: Upgrade to FDL version 1.2.
7878 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Use the function f
7879 nontrivially in main's body, so that f's external declaration is
7880 not optimized away in AIX. This should fix the bug reported by
7882 <http://mail.gnu.org/pipermail/autoconf/2002-November/014508.html>.
7884 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C),
7885 _AC_PROG_PREPROC_WORKS_IFELSE): Use <limits.h> if __STDC__ is
7886 defined, to support freestanding compilers. This should fix the
7887 bug reported by Momchil Velkov in
7888 <http://mail.gnu.org/pipermail/autoconf/2002-November/014490.html>.
7890 * doc/autoconf.texi (Obsolete Macros): Fix typos (insert empty
7891 arg, AC_DEFINE -> AC_DEFINE_UNQUOTED) in documentation for
7892 obsolete AC_CHECK_TYPE. The missing empty arg was reported
7893 by Simon Josefsson in
7894 <http://mail.gnu.org/pipermail/autoconf-patches/2002-December/008830.html>.
7896 * Makefile.maint (www-gnu): New macro.

7898 the location has moved.
7900 2002-12-02 Martin Frydl <martin@systinet.com>
7902 * bin/autom4te.in (at_flatten): rewritten to avoid M4 problem when
7903 \(.*\) match is too long and there is something more to be checked.
7904 <http://mail.gnu.org/pipermail/autoconf/2002-November/014524.html>

7922 Update from masters.
7924 2002-11-14 Akim Demaille <akim@epita.fr>
7926 * Makefile.maint: Sync with Bison, i.e.:
7927 (po-check): Scan .l and .y files instead of the
7928 .c and the .h files that they generate. This fixes the bug
7929 reported by Tim Van Holder in:
7930 <http://mail.gnu.org/pipermail/bison-patches/2002-November/001352.html>
7931 Look for N_ as well as for _. Try to avoid matching #define for
7935 2002-11-14 Akim Demaille <akim@epita.fr>
7937 * doc/autoconf.texi (C Compiler): Compiling several files at once.
7938 From Paul Eggert and Albert Chin-A-Young.
7940 2002-11-14 Akim Demaille <akim@epita.fr>
7942 * doc/autoconf.texi (C Compiler): Solitary backslashes.
7943 From Paul Eggert and Albert Chin-A-Young.
7945 2002-11-14 Kevin Ryde <user42@zip.com.au>
7947 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY(C)): Initialize f=$1 rather
7948 than assigning in main, to avoid HP cc +O3 optimizing it away.
7950 2002-11-12 Peter Eisentraut <peter_e@gmx.net>
7952 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Add -q
7953 option. Process --recheck after parsing all options. Pass -q
7954 option to configure on --recheck.
7955 (AC_OUTPUT): Pass -q from configure to config.status.
7956 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Strip -q from
7957 arguments to record.
7958 * doc/autoconf.texi (config.status Invocation): Document
7959 config.status -q option.
7961 2002-11-07 Alexandre Duret-Lutz <adl@gnu.org>
7963 * bin/autoscan.in (scan_file): Scan Makefile.am too. Ignore

7977 * lib/autoconf/c.m4 (AC_LANG_FUNC_LINK_TRY): Wrap the `f'
7978 declaration in extern "C" too.
7979 Reported by Roberto Bagnara.

7983 * tests/torture.at (Configuring subdirectories): Don't use grep
7985 * doc/autoconf.texi (Limitations of Usual Tools): Grep -w.
7986 Reported by Ezra Peisach.
7988 2002-11-05 Akim Demaille <akim@epita.fr>
7990 * lib/autoconf/autoheader.m4 (_AH_TEMPLATE_OLD, _AH_VERBATIM_OLD):
7992 We _have_ to stop using the old compatibility scheme that tried to
7993 avoid useless backslashes because Libtool 1.4.3 contains a
7994 AC_DEFINE([error_t], [int],
7995 [Define to a type to use for \`error_t' if it is not
7996 otherwise available.])
7997 We _have_ to quote the single quote and backslashes with \. The
7998 old compatibility scheme saw that ` was backslashed, and therefore
7999 did not quote the single quote. Hence before this patch, Autoconf
8000 was not compatible with Libtool.
8002 2002-11-04 Paul Eggert <eggert@twinsun.com>
8004 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Set the following variables,

8015 * config/texinfo.tex: Update.
8017 2002-11-03 Akim Demaille <akim@epita.fr>
8019 * bin/autoreconf.in (&autoreconf_current_directory): New, extracted
8021 (&autoreconf): here.
8022 ($help, $make, &parse_args, &autoreconf_current_directory):

8454 * bin/autoreconf.in (&autoreconf): Run autopoint before the first
8455 aclocal invocation, as Gettext macros might not be visible to
8457 Instead of blindly running autopoint, scan configure.ac (not the

8549 * lib/autoscan/autoscan.list: this.
8550 * bin/autoscan.in (&init_tables): Adjust.
8552 2002-09-28 Akim Demaille <akim@epita.fr>
8554 * lib/autoscan/functions, lib/autoscan/headers,
8555 * lib/autoscan/identifiers, lib/autoscan/makevars,

8557 `functions' line is now prefixed with `function:'.
8558 * bin/autoscan.in (&init_tables): Adjust.
8560 2002-09-28 Akim Demaille <akim@epita.fr>
8562 From now on, autoscan files must always map a macro name to a
8563 word: there is no `default' macro for autoscan.
8565 * bin/autoscan.in (&init_tables): Reject entries with no macro at
8567 * lib/autoscan/functions, lib/autoscan/headers: Make the macro
8570 2002-09-28 Akim Demaille <akim@epita.fr>
8572 * bin/autoscan.in (%c_keywords): Remove.
8573 (&used): Keep only track of the words we might be interested in.

8584 2002-09-27 Akim Demaille <akim@epita.fr>
8586 * doc/autoconf.texi (Limitations of Usual Tools): Some about mv
8588 Thanks to Bill Moseley and Paul Eggert.
8589 * lib/m4sugar/m4sh.m4 (AS_TMPDIR): $2 is the directory into which
8590 the tmpdir must be created.
8591 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): Have the tmp
8592 dir be in the build tree, instead of $TMPDIR.

8596 * bin/autoscan.in: Improve the comments.
8597 (&parse_args): Drop obsolete undocumented options.
8598 (&output_kind): Output warnings.
8599 * lib/autoscan/functions: (dcgettext): Now trigger AM_GNU_GETTEXT.

8602 2002-09-26 Akim Demaille <akim@epita.fr>
8604 * bin/autoreconf.in: Clarify that -s is meaningless without -i.
8605 Reported by Ralf Corsepius.
8606 * doc/autoconf.texi (autoreconf Invocation): Likewise.
8608 2002-09-26 Akim Demaille <akim@epita.fr>
8610 Single suffix rules and seperated dependencies are not portable.
8612 * doc/autoconf.texi (Installation Directory Variables): Update.
8613 (Limitations of Make): Some about `Single Suffix Rules and
8614 Separated Dependencies'.
8615 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8616 (ifnames, autoscan, autom4te): Un-factor into several rules.
8618 2002-09-25 Paul Eggert <eggert@twinsun.com>
8620 * BUGS (Interoperability bugs): New section. Mention libtool
8621 1.4.2, configure.ac, and AC_CONFIG_AUX_DIR interoperability bug.
8623 2002-09-24 Paul Eggert <eggert@twinsun.com>
8625 Fix a portability bug reported by Alexandre Duret-Lutz: Solaris 8
8626 make handles suffix-rules differently from GNU make.
8628 * bin/Makefile.am (SUFFIXES, .in): Remove.
8629 (autoconf autoheader autoreconf autoupdate ifnames autoscan autom4te):
8630 Move the body of the old .in rule here.
8632 2002-09-16 Akim Demaille <akim@epita.fr>
8634 i960 compilers create `b.out' files by default.
8635 Reported by Ralf Corsepius.
8637 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT): Remove b.out files.
8638 (_AC_COMPILER_EXEEXT_DEFAULT): Adjust to b.out.
8640 2002-09-13 Paul Eggert <eggert@twinsun.com>
8642 * doc/autoconf.texi (Particular Headers): Remove obsolete
8643 reference to `struct timezone' in the description of
8646 2002-09-13 Akim Demaille <akim@epita.fr>
8650 * config/config.sub, config/config.guess: Update.
8651 * Makefile.maint: Update from bits of the Coreutils 4.5.1.
8652 * Makefile.am: Adjust.
8654 2002-09-13 Akim Demaille <akim@epita.fr>
8656 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Suggest
8657 reading config.log when the compiler is rejected.
8658 Suggested by Guido Draheim.
8660 2002-09-13 Akim Demaille <akim@epita.fr>
8662 * bin/autoreconf.in: Don't use Cwd::chdir, since in its internals
8663 (chdir_init) might hang when stat'ing mounted directories.
8664 Reported by Vance Shipley.
8666 2002-09-12 Akim Demaille <akim@epita.fr>
8668 * bin/autoscan.in (&parse_args): Pass a reference to the lists, not
8671 2002-09-12 Akim Demaille <akim@epita.fr>
8673 * doc/autoconf.texi (Defining Symbols): Present two different
8674 prototypes for AC_DEFINE and AC_DEFINE_UNQUOTED to emphasize the
8675 difference between 1 argument calls, and 2-3 argument calls.
8677 2002-09-12 Peter Eisentraut <peter_e@gmx.net>
8679 * doc/autoconf.texi: Review grammar and punctuation.
8681 2002-09-11 Paul Eggert <eggert@twinsun.com>
8683 * doc/autoconf.texi: Fix minor formatting, spelling, and
8685 (Defining Symbols): Explain that AC_DEFINE(var) defaults to 1, but
8686 AC_DEFINE(var,,description) does not; and the AC_DEFINE(var) case
8689 2002-09-11 Akim Demaille <akim@epita.fr>
8691 * doc/autoconf.texi (Questions): Rename as...
8693 (Defining Directories): New.
8695 2002-09-09 Akim Demaille <akim@epita.fr>
8697 * doc/autoconf.texi (Making testsuite Scripts): Update.
8698 Suggested by Nishio Futoshi.
8700 2002-09-09 Koji Arai <JCA02266@nifty.ne.jp>
8702 * doc/autoconf.texi (Making testsuite Scripts): Use `@@' where a
8703 plain `@' is wanted.
8705 2002-09-09 Akim Demaille <akim@epita.fr>
8707 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Keep the
8708 `duplicates', since the algorithm was too naive and could keep
8709 `--prefix=1 --prefix=2 --prefix=1' as `--prefix=1 --prefix=2', and
8710 keep `--prefix foo --prefix bar' as `--prefix foo bar'.
8711 Reported by Ralf Corsepius.
8712 * tests/torture.at (Configuring subdirectories): Exercise these
8715 2002-09-09 Akim Demaille <akim@epita.fr>
8717 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Use $srcdir when
8718 looking for a replacement file.
8719 * lib/autoconf/general.m4 (AC_CHECK_DECLS): Check that the
8720 directory is relative.
8721 * doc/autoconf.texi (Generic Functions): Clarify the replacement
8722 directory definition.
8723 Reported by Andreas Schwab and Jim Meyering.
8725 2002-09-06 Akim Demaille <akim@epita.fr>
8727 * doc/autoconf.texi (Setting Output Variables): Clarify what
8728 precious variables are.
8729 Suggested by Pontus Skoeld.
8731 2002-09-05 Akim Demaille <akim@epita.fr>
8733 * bin/Makefile.am (autoconf, autoheader, autoreconf, autoupdate)
8734 (ifnames, autoscan, autom4te): Since we don't only depend on
8735 configure.ac variables (such as VERSION etc.), but also on prefix
8736 and so forth, depend on Makefile, not configure.ac.
8737 Reported by Alexandre Duret-Lutz.
8738 * doc/autoconf.texi (Installation Directory Variables): Adjust.
8740 2002-09-05 Kevin Ryde <user42@zip.com.au>
8742 * doc/autoconf.texi (Limitations of Make): HP-UX trailing backslashes
8743 doesn't seem to be confined to ia64, just say "some versions".
8745 2002-09-04 Akim Demaille <akim@epita.fr>
8747 * Makefile.am, doc/Makefile.am: Remove pdf targets, handled by
8749 * Makefile.am (maintainer-clean-local): Remove.
8750 (MAINTAINERCLEANFILES): Remove COPYING.
8752 2002-09-03 Paul Eggert <eggert@twinsun.com>
8754 * doc/autoconf.texi (Configuration Commands): Remove obsolete
8755 example for AC_CONFIG_COMMANDS_PRE. Problem reported by Marcus
8758 2002-09-03 Akim Demaille <akim@epita.fr>
8760 * configure.ac: Bump to 2.53d.
8761 * Makefile.am (AUTOMAKE_OPTIONS): Require 1.6c, i.e., CVS Automake
8762 as of today, on Automake's team suggestion.
8764 2002-09-03 Akim Demaille <akim@epita.fr>
8768 2002-09-02 Akim Demaille <akim@epita.fr>
8770 * bin/autom4te.in (parse_args): Don't honor AUTOM4TE_PATH and
8772 * configure.ac: Disable SITE_MACRO_DIR.
8774 2002-09-02 Jim Meyering <meyering@lucent.com>
8776 * doc/autoconf.texi (AC_SYS_POSIX_TERMIOS): Reflect renaming: s/am/ac/,
8777 i.e., change am_cv_sys_posix_termios to ac_cv_sys_posix_termios.
8778 Also, tweak grammar: s/make sure to/be sure to/.
8780 2002-09-02 Paul Eggert <eggert@twinsun.com>
8782 * doc/autoconf.texi (Limitations of Builtins): Explain why logical
8783 directory names are generally preferable to physical names.
8785 2002-09-02 Akim Demaille <akim@epita.fr>
8787 * lib/Autom4te/General.pm (&update_file): s/die/error/.
8788 Reported by Raja R. Harinath.
8789 * bin/autoheader.in, bin/autoreconf.in, bin/autoscan.in,
8790 * bin/autoupdate.in: Use error instead of die.
8792 2002-09-01 Paul Eggert <eggert@twinsun.com>
8794 * tests/mktests.sh (ac_exclude_egrep, au_exclude_egrep): Use
8795 ordinary shell concatenation rather than echo+tr+sed command that
8796 runs afoul of a long-line-related sed bug in Solaris 8.
8798 * bin/autoheader.in (parse_args): --warning -> --warnings.
8800 * bin/autoconf.as: Work even if "ls" outputs "FOO not found" to
8801 stdout, as traditional "ls" does.
8802 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT,
8803 _AC_COMPILER_EXEEXT_O): Likewise.
8804 * doc/autoconf.texi (Limitations of Usual Tools): Add "ls".
8806 * bin/autoconf.as: Add --prepend-include option. This patch was
8807 applied to bin/autoconf.in in the 2002-07-17 patch by Mark D. Roth,
8808 but bin/autoconf.in is generated automatically from bin/autoconf.as.
8810 * bin/autoconf.in, configure: Regenerate.
8812 * doc/autoconf.texi (Special Shell Variables): Mention
8813 ENV, MAIL, MAILPATH, PS1, PS2, PS4. Index PWD.
8815 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Unset ENV, MAIL,
8816 MAILPATH and set PS1, PS2, PS4 to default values, to work
8817 around bug in pre-3.0 UWIN ksh reported by Bruce Lilly.
8818 For LC_ALL etc, first try to set to "C" as POSIX requires and as
8819 the Autoconf documentation specifies; fall back to "unset" only if
8820 this fails. Use a shell for-loop for this rather than an m4 loop,
8821 to shorten the output script.
8823 2002-08-30 Paul Eggert <eggert@twinsun.com>
8825 * doc/autoconf.texi (Special Shell Variables): Mention POSIX
8826 1003.1-2001's requirements for CDPATH. Give a simpler workaround
8827 for the CDPATH problem. Document PWD.
8828 (Limitations of Builtins): Document the problem that "cd $foo" and
8829 "ls $foo" may refer to different directories in shells conforming
8830 to POSIX 1003.1-2001. Use PS1 rather than CDPATH for "unset"
8831 example, since the old example is now out of date.
8833 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR): Reject FOO if "cd
8834 FOO" and "ls FOO" talk about different directories; this catches
8835 problems when POSIX 1003.1-2001 "cd" fails due to symlink
8838 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Use AS_UNSET instead
8839 of rolling our own unset.
8840 (_AS_PREPARE): $as_unset CDPATH instead of AS_UNSETting it, since
8841 in practice we needn't worry about CDPATH if unset doesn't work.
8843 * Makefile.in, aclocal.m4, bin/Makefile.in,
8844 config/Makefile.in, doc/Makefile.in, lib/Makefile.in,
8845 lib/Autom4te/Makefile.in, lib/autoconf/Makefile.in,
8846 lib/autoscan/Makefile.in, lib/autotest/Makefile.in,
8847 lib/emacs/Makefile.in, lib/m4sugar/Makefile.in, man/Makefile.in,
8848 tests/Makefile.in: Regenerate with Automake 1.6.3.
8850 * config/config.guess, config/config.sub, config/mkinstalldirs:
8853 * configure: Regenerate with self.
8855 2002-08-30 Kevin Ryde <user42@zip.com.au>
8857 * doc/autoconf.texi (Limitations of Usual Tools): Notes on "cc"
8860 2002-08-29 Rainer Orth <ro@TechFak.Uni-Bielefeld.DE>
8862 * bin/autom4te.in (Request::load): Correctly test for "do" read
8865 2002-08-29 Akim Demaille <akim@epita.fr>
8867 * lib/Autom4te/General.pm (&xqx): New.
8868 (&xsystem): Use WIFEXITED and WEXITSTATUS instead of decoding $? by
8869 hand, which is not portable.
8871 * bin/autom4te.in: Use them.
8872 Use &error instead of die.
8873 * tests/m4sugar.at (m4_warn, m4_require: circular dependencies):
8876 2002-08-17 Paul Eggert <eggert@twinsun.com>
8878 * lib/autoconf/fortran.m4 (AC_PROG_F77): Remove fc from the
8879 default list of compilers to try, since it was long ago superseded
8880 by the ksh fc builtin. Suggested by Steven G. Johnson.
8882 2002-07-31 Alexandre Duret-Lutz <duret_g@epita.fr>
8884 * doc/autoconf.texi (Invoking autom4te): End the option table,
8885 fixing a bug introduced by the previous patch.
8886 (Limitations of Make): Add a 'target lookup' subentry in the
8887 'VPATH' entry. Rewrite all `make' occurences as `@command{make}'.
8889 2002-07-29 Mark D. Roth <roth@feep.net>
8891 * bin/autom4te.in: Remove --include-envvar and --site-macro-subdir
8892 options and use $AUTOM4TE_PATH.
8893 * doc/autoconf.texi: Remove documentation of autom4te
8894 --include-envvar and --site-macro-subdir options and document
8895 use of $AUTOM4TE_PATH.
8896 * lib/autom4te.in: Remove --include-envvar and --site-macro-subdir
8897 arguments from each language section.
8899 2002-07-29 Paul Eggert <eggert@twinsun.com>
8901 * doc/install.texi: Include copyright symbol in copyright notice.
8903 * Makefile.am (MAKEINFO): Remove; it's a user-specified macro.
8905 (AM_MAKEINFOFLAGS): New macro.
8906 * doc/Makefile.am (MAKEINFO, AM_MAKEINFOFLAGS): Likewise.
8907 * Makefile.am (INSTALL): Use the new macros.
8908 Use -o rather than --output, since "missing" does not grok --output.
8910 2002-07-25 Alexandre Duret-Lutz <duret_g@epita.fr>
8912 * doc/autoconf.texi (Limitations of Make): Escaped newlines in
8913 comments do not always work. Never trust the exit status of
8916 2002-07-24 Kevin Ryde <user42@zip.com.au>
8918 * doc/autoconf.texi (Limitations of Make, Making testsuite Scripts):
8919 Untabify, since tabs are not enjoyed by texi2dvi and makeinfo.
8921 2002-07-23 Paul Eggert <eggert@twinsun.com>
8923 * lib/m4sugar/m4sh.m4 (_AS_PATH_SEPARATOR_PREPARE):
8924 Use PATH="/nonexistent;.", not PATH=".;.", as FreeBSD ksh2002
8925 apparently treats PATH="nonexistent" as if it contained ".".
8926 Bug reported by Stefan `Sec' Zehl.
8928 2002-07-22 Alexandre Duret-Lutz <duret_g@epita.fr>
8930 * doc/autoconf.texi (Limitations of Make): Mention the special
8931 handling of the obj/ directory by BSD make.
8933 2002-07-20 Kevin Ryde <user42@zip.com.au>
8935 * doc/autoconf.texi (Limitations of Make): Add HP-UX IA-64 trailing
8938 2002-07-19 Akim Demaille <akim@epita.fr>
8940 * doc/autoconf.texi (Function Portability): `exit'.
8941 (Programming in M4sh): Ethymology of M4sh.

8967 * lib/autoconf/status.m4 (_AC_OUTPUT_HEADERS): Install
8968 _AC_AM_CONFIG_HEADER_HOOK for Automake 1.7.
8970 2002-07-17 Russ Allbery <rra@stanford.edu>
8972 * doc/autoconf.texi (Initializing configure): Clarify the
8973 description of the tarname default.

8984 the order they are given.
8986 2002-07-17 Akim Demaille <akim@epita.fr>
8988 * tests/wrapsh.as, tests/wrappl.as: Merge into...
8989 * tests/wrapper.as: this.

9002 * bin/autoupdate.in: Add --prepend-include option.
9003 * doc/autoconf.texi: Document use of $AC_MACRO_PATH and site
9004 macro directory, remove note that include path directories are
9005 used in reverse order, and document --prepend-include option.
9006 * lib/autom4te.in: Use --prepend-include instead of --include.
9007 * tests/wrapsh.in: Use --prepend-include instead of --include.
9009 2002-07-17 Akim Demaille <akim@epita.fr>

9198 2002-05-16 Paul Eggert <eggert@twinsun.com>
9200 AC_FUNC_FNMATCH now tests only for POSIX compatibility.
9201 AC_FUNC_FNMATCH_GNU also tests for GNU extensions.
9202 Both macros now accept an optional source-dir arg.
9203 New macro AC_GNU_SOURCE to define _GNU_SOURCE.
9205 * NEWS: Document this.
9206 * doc/autoconf.texi (Particular Functions, UNIX Variants): Likewise.
9208 * lib/autoconf/functions.m4 (_AC_FUNC_FNMATCH): New macro.
9209 (AC_FUNC_FNMATCH): Use it. Test only for POSIX conformance,

9222 Bug reported by Stephen Gildea.
9224 * lib/autoconf/functions.m4 (AC_FUNC_SETVBUF_REVERSED):
9225 If prototypes are supported, use them to check this at compile-time,
9226 instead of trying to check it at run-time. If we must do a run-time
9227 check, assume that setvbuf is standard when cross-compiling, as
9228 nonstandard setvbuf occurs only on ancient and unlikely hosts.
9229 Bug reported by Paul D. Smith.
9231 * lib/autoconf/functions.m4 (AC_FUNC_GETLOADAVG): Add optional
9232 argument specifying location of getloadavg.c. This removes a
9233 FIXME. This idea was taken from Jim Meyering's implementation in
9235 * doc/autoconf.texi (Particular Functions): Document this.
9236 Also, mention HAVE_NLIST_H rather than NLIST_STRUCT, since
9237 that's what the code does; this fixes a bug reported by

9243 autopoint instead of gettextize.
9244 ($uses_alocal): Rename as...
9245 ($uses_aclocal): this.

9247 Suggested by Bruno Haible.

9253 2002-04-29 Paul Eggert <eggert@twinsun.com>
9255 * bin/autoreconf.in (autoreconf): Don't age aclocal.m4's input
9256 files to be 1 second older; just set them to be the same time.
9257 Also, sleep 1 second after the first aclocal, to work around
9258 problems with sub-second time stamps on the input files.
9260 2002-04-29 Thien-Thi Nguyen <ttn@gnu.org>
9262 * doc/autoconf.texi: Mention "set -e -x" lossage

9271 2002-04-29 Akim Demaille <akim@epita.fr>
9273 * tests/m4sh.at (LINENO): If testsuite itself is rewritten because
9274 of lack of $LINENO support, then the test will compare the $LINENO
9275 in testsuite vs. the lineno in the test file. This is wrong, of
9277 Be sure to protect it.
9278 Reported by Patrick Welche.
9280 2002-04-25 Akim Demaille <akim@epita.fr>
9282 * doc/autoconf.texi (Obsolete Macros): Typo.
9283 Reported by Vladimir Volovich.
9285 2002-04-25 Akim Demaille <akim@epita.fr>
9287 * bin/autoreconf.in (autoreconf): Don't let aclocal.m4 be older
9288 than some of the input files, hence, on the second run of aclocal,
9289 if some of its input are younger, make them older.
9290 Suggested by Paul Eggert.
9292 2002-04-25 Akim Demaille <akim@epita.fr>
9294 * doc/autoconf.texi (Limitations of Usual Tools): sed and `!'.

9300 and ac_subst_vars be sh variables containing the list of
9301 AC_SUBST_FILES'ed and AC_SUBST'ed identifiers. Output them in the
9303 (_AC_INIT_PREPARE): Use them to log them.
9304 (_AC_SUBST, _AC_SUBST_SED_PROGRAM): Remove.
9305 (AC_SUBST, AC_SUBST_FILE): Instead of buliding the
9306 _AC_SUBST_SED_PROGRAM, store the list of output files/variables in

9310 2002-04-24 Akim Demaille <akim@epita.fr>
9312 * bin/autoreconf.in (autoreconf): Run automake after autoconf and
9313 autoheader, so that automake does not complain about a missing
9314 config.h.in that was to be created.
9316 2002-04-23 Akim Demaille <akim@epita.fr>

9554 about VPATH, overriding of macros in sub-makes, and handling of
9557 2002-03-21 Paul Eggert <eggert@twinsun.com>
9559 * doc/autoconf.texi (Here-Documents): Mention Solaris 8 dtksh
9560 problem with here-document buffer boundaries.
9562 * lib/m4sugar/m4sh.m4 (_AS_LINENO_PREPARE): Unset ENV and BASH_ENV
9563 when reinvoking the shell, to work around problems with installers
9564 who put strange things like "cd" commands in their environments.
9566 2002-03-19 Akim Demaille <akim@epita.fr>
9568 * tests/semantics.at (AC_C_BIGENDIAN): s/unknow/unknown/.

9580 From Nishio Futoshi.
9582 2002-03-19 Akim Demaille <akim@epita.fr>
9584 * lib/m4sugar/m4sugar.m4 (m4_define_default, m4_fst, m4_map): New.
9586 2002-03-18 Paul Eggert <eggert@twinsun.com>
9588 * doc/autoconf.texi (Programming in M4sh): Add AS_MKDIR_P.
9589 (Limitations of Usual Tools): Add mkdir section.
9591 * lib/m4sugar/m4sh.m4 (_AS_MKDIR_P_PREPARE): New macro.
9592 (AS_MKDIR_P): Require it. Use mkdir -p if available, falling
9593 back on AS_DIRNAME to compute prefixes otherwise; this is
9594 roughly what mkinstalldirs does. That way, we need not have
9595 our own filename disassembler. The old disassembler did not
9596 work with Solaris 8 dtksh, which is ksh Version M-12/28/93d.
9598 * lib/autotest/general.m4 (AT_INIT, AT_CLEANUP):
9599 Create at_test_all by a series of assignments,
9600 not by a single assignment of a long string. The latter causes ksh
9601 version 11/16/88g to silently misbehave on OpenServer 5.0.6a,
9602 presumably because of a buffer overrun.
9604 2002-03-14 Paul Eggert <eggert@twinsun.com>
9606 * lib/autotest/general.m4 (at_times_skip):
9607 Renamed from at_times. Now a boolean.
9608 ksh93 Version M-12/28/93d doesn't like 'x=times; $x'; it
9609 says 'times: not found'.
9611 2002-03-14 Akim Demaille <akim@epita.fr>
9613 * bin/autoreconf.in (&study_gettextize): New.
9614 (&autoreconf): Handle newest gettextize.

9656 2002-03-08 Akim Demaille <akim@epita.fr>
9658 * bin/autom4te.in (&handle_m4): Do not foreach with `$_' as it
9659 aliases the actual variables, and modifications of the former
9662 2002-03-08 Akim Demaille <akim@epita.fr>
9664 * bin/autom4te.in (&handle_m4): Protect us from corrupted file
9665 because of C-c: have m4 output in tmp files, then mv them.

9697 2002-03-04 Akim Demaille <akim@epita.fr>
9699 * doc/autoconf.texi (Transforming Names): Equality between target
9700 and host is irrelevant.
9701 (Specifying Names, Canonicalizing): Remove all references to the
9702 backward compatibility hooks. Rather, collect them all into...
9703 (Hosts and Cross-Compilation): this new section.
9704 * doc/install.texi (System Type): Ditto.
9705 * lib/autoconf/general.m4 (AC_CANONICAL_HOST): Explicitly state
9706 that `--host' implies cross-compilation.
9708 2002-03-04 Akim Demaille <akim@epita.fr>
9710 * doc/autoconf.texi (Evaluation Macros): New.
9711 * lib/m4sugar/m4sugar.m4 (m4_lquote): Remove, it is totally
9713 (_m4_foreach): Define the variant with immediate evaluation so
9714 that it contains exactly the items, not an expression which
9715 evaluation is the current item.
9716 (m4_re_string, m4_re_word): Don't over quote them.
9718 2002-03-04 Akim Demaille <akim@epita.fr>
9720 Instead of having stacking `shift's evaluated at the end, let
9721 `foreach' loops immediately evaluate them.
9723 * lib/m4sugar/m4sugar.m4 (m4_quote, m4_dquote): Use $@ rather than
9724 $*. This is the n-th time I change my mind, but hopefully this is
9727 (m4_text_wrap): Use m4_foreach, which is finally correct _and_
9729 (m4_foreach_quoted, m4_car_quoted, _m4_foreach_quoted): Remove, as
9730 it was only a hack for m4_text_wrap.
9731 (m4_car2): Remove, replaced by...
9733 (_m4_foreach): Adjust.
9734 * lib/autoconf/general.m4 (_AC_INIT_PREPARE): Adjust, and use
9735 m4_bpatsubst for clarification.
9737 2002-03-04 Akim Demaille <akim@epita.fr>

9828 * tests/Makefile.am (check_SCRIPTS): Use it, instead of WRAPPERS,

9893 2002-01-28 Akim Demaille <akim@epita.fr>
9895 * lib/autotest/general.m4 (AT_INIT): Don't be ridiculous: adjust
9896 AUTOTEST_PATH *after* it was set.
9897 Don't put `.' in the PATH: the user should be precise and `./' if
9898 needed. In addition, given that the test suite does some `cd', if
9899 `.' is in the path, the `tested programs' sections will report
9900 programs found in the test suite's directory, while during the
9901 tests (performed in their own directory), these programs are no
9902 longer visible. In other words, the results is confusing and

10089 2001-11-26 Akim Demaille <akim@epita.fr>
10091 * doc/autoconf.texi (Using an Autotest Test Suite): New.
10092 (testsuite Scripts): Be one of its subsection.
10093 (Autotest Logs): New.
10095 2001-11-26 Akim Demaille <akim@epita.fr>
10097 Test groups are now run two directories deeper.
10099 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Replace srcdir,
10100 top_srcdir and top_builddir with at_srcdir, at_top_srcdir and
10102 * lib/autotest/general.m4 (AT_INIT): Compute srcdir,
10103 top_srcdir, builddir and top_builddir.
10104 Use `at_*dir' relatively to the directory containing the
10105 suite, use `*dir' when relatively to the current group dir.
10107 2001-11-25 Joseph S. Myers <jsm28@cam.ac.uk>
10109 * doc/autoconf.texi, TODO, lib/autoconf/fortran.m4,
10110 lib/autoconf/functions.m4, lib/autoconf/headers.m4,
10111 tests/atgeneral.m4, tests/tools.at, tests/atspecific.m4: Fix
10114 2001-11-22 Alexandre Duret-Lutz <duret_g@epita.fr>
10116 * doc/autoconf.texi (Using System Type): Add an example of `case
10117 $host' usage so people quit using `case $target' everywhere.
10119 2001-11-22 Akim Demaille <akim@epita.fr>
10121 * doc/autoconf.texi (Installation Directory Variables): Englishoes
10122 spotted by Jim Meyering.
10124 2001-11-16 Paul Eggert <eggert@twinsun.com>
10126 This patch implements a `long double' suggestion by Oliver Kiddle.
10128 * lib/autoconf/c.m4 (AC_LANG_BOOL_COMPILE_TRY(C)): Make the array
10129 static, to catch errors if the value isn't known at compile-time
10130 and the compiler supports dynamic arrays. Change its name from
10131 `_array_' to `test_array' to avoid potential name clashes.
10132 (AC_C_LONG_DOUBLE): Make it a compile-time test, not a run-time
10133 test. Do not define HAVE_LONG_DOUBLE if `long double' is no
10134 better than double. Catch a bug in GCC 2.95.2 x86.
10135 * doc/autoconf.texi (C Compiler): Document the above.
10138 2001-11-13 Akim Demaille <akim@epita.fr>
10140 * tests/m4sh.at (LINENO): Protect from autom4te's substitution by
10142 * tests/tools.at: Don't protect dnl, AT_DATA_M4SH does.
10144 2001-11-13 Akim Demaille <akim@epita.fr>
10146 * lib/autotest/general.m4 (AT_INIT): After having run the test
10147 group, go back to the initial directory, not to at_suite_dir.
10149 2001-11-13 Akim Demaille <akim@epita.fr>
10151 * tests/atspecific.m4 (AT_DATA_M4SUGAR, AT_DATA_M4SH)
10152 (AT_DATA_AUTOCONF): Also protect @&t@ from autom4te.
10153 (AT_CHECK_AUTOCONF, AT_CHECK_AUTOHEADER): Pass no --include
10155 (AT_CHECK_CONFIGURE): Use absolute paths.
10156 (_AT_CHECK_AC_MACRO): Create aclocal.m4 with AC_STATE_SAVE in it.
10157 The problem is still the old one: there is no means in M4 (that I
10158 know about) to create a defining macro, because there is no means
10159 to create `$1' etc., therefore, the defining macro ``swallows''
10160 all the arguments meant to the defined macro.
10162 2001-11-13 Akim Demaille <akim@epita.fr>
10164 * tests/atspecific.m4 (AT_DATA_AUTOCONF): New.
10165 (AT_CONFIGURE_AC): Output the definition of AC_STATE_SAVE in
10167 * tests/aclocal.m4: Remove, as it is no longer used.
10169 2001-11-13 Akim Demaille <akim@epita.fr>
10171 * lib/autotest/general.m4: Change `tests?' into `groups?' in
10172 variable names when referring to a single test group, or to
10173 `suite' when referring to the whole test suite.
10174 `at_last_test' is removed: m4 compute at_format itself.
10175 (at_stdout, at_stder1, at_stderr): New variables.
10176 (AT_CHECK): Use them.
10178 2001-11-13 Akim Demaille <akim@epita.fr>
10180 * lib/autotest/general.m4 (AT_INIT): Be sure to put `.', relative,
10182 Create `testsuite.dir/003/run' instead of `testsuite.003'.
10183 Do it as soon as a test fails, don't wait till the end of the test
10185 Don't remove $as_me.[0-9]*, since these files no longer exist.
10187 2001-11-13 Akim Demaille <akim@epita.fr>
10189 * tests/tools.at: Use absolute paths, since we are no longer run
10192 2001-11-13 Akim Demaille <akim@epita.fr>
10194 Now that tests are running in their own private dir, there is no
10195 need to list the files to remove at the end of tests groups.
10197 * lib/autotest/general.m4 (_AT_CLEANUP_FILE, AT_CLEANUP_FILES):
10198 (AT_data_files, at_data_files): Remove.
10199 (AT_CLEANUP, AT_DATA): Simplify.
10201 Remove the group dir if !debug && !failed.
10202 * tests/atspecific.m4: Adjust.
10204 2001-11-13 Akim Demaille <akim@epita.fr>
10206 Start a new layout for Autotest: `testsuite' creates
10207 `testsuite.dir' in which the at-check-line etc. files are to be
10208 found, and `testsuite.dir/003' where the test group 3 is run.
10210 * lib/autotest/general.m4 (AT_INIT): at_tests_dir,
10211 at_check_line_file, at_format, at_test_normalized, at_group_dir
10213 Create the directories.
10214 Use absolute paths for at- files.
10215 (AT_CHECK): Adjust.
10217 2001-11-11 Michael Matz <matz@kde.org>
10219 * m4sugar.m4 (_m4_foreach): Make it linear instead quadratic.
10221 (m4_car): Properly quote arguments.
10223 2001-11-13 Akim Demaille <akim@epita.fr>
10225 * tests/aclocal.m4 (AC_STATE_SAVE): s/LIBOBJS/LIB@&t@OBJS/ to cope
10226 with stricter rules on LIBOBJS.
10228 2001-11-12 Paul Eggert <eggert@twinsun.com>
10230 * lib/autoconf/c.m4 (AC_C_PROTOTYPES): Define __PROTOTYPES too.
10231 * doc/autoconf.texi (C Compiler): AC_C_PROTOTYPES now defines
10234 2001-11-12 Akim Demaille <akim@epita.fr>
10236 * lib/autoconf/functions.m4 (AC_FUNC_GETMNTENT): Use AC_CHECK_FUNCS.
10238 2001-11-12 Akim Demaille <akim@epita.fr>
10240 * lib/autoconf/c.m4, lib/autoconf/fortran.m4,
10241 * lib/autoconf/functions.m4, lib/autoconf/general.m4,
10242 * lib/autoconf/headers.m4, lib/autoconf/libs.m4,
10243 * lib/autoconf/programs.m4, lib/autoconf/specific.m4,
10244 * lib/autoconf/types.m4: When invoking AC_DEFINE and friends,
10245 specify to what the macro should be defined (typically to 1).
10247 2001-11-12 Akim Demaille <akim@epita.fr>
10249 * lib/autoconf/functions.m4 (AC_FUNC_STRTOD): AC_SUBST POW_LIB.
10252 2001-11-12 Akim Demaille <akim@epita.fr>
10254 * lib/autoconf/programs.m4 (_AC_PROG_LEX_YYTEXT_DECL): Use
10255 AC_TRY_EVAL to run $LEX, not AC_TRY_COMMAND. This validates the
10256 definition used by Automake where LEX is +/- "${missing} lex" and
10257 `missing' itself contains variables.
10259 2001-11-12 Akim Demaille <akim@epita.fr>
10261 * lib/autotest/general.m4 (AT_INIT): Push KILL at the end.
10262 Now that M4sh pushes BODY, the comments were output at the end of
10265 2001-11-08 Akim Demaille <akim@epita.fr>
10267 * bin/autoreconf.in (&autoreconf): Run aclocal before tracing, so
10268 that we can trace macros from aclocal.m4.
10269 Trace AC_PROG_LIBTOOL, not AM_PROG_LIBTOOL, since the latter is
10270 obsoleted, and redirect to the former anyway.
10271 Reported by Ralf Corsepius.
10273 2001-11-08 Akim Demaille <akim@epita.fr>
10275 * bin/autoreconf.in (&autoreconf): AC_CONFIG_SUBIDRS are to be
10276 processed only if present.
10277 * tests/torture.at (Configuring subdirectories): Use autoreconf
10278 instead of successive calls to autoconf.
10279 Add a nonexistent subdirectory to exercise the patch above.
10280 Reported by Ralf Corsepius.
10282 2001-11-08 Kevin Ryde <user42@zip.com.au>
10284 * doc/autoconf.texi (Limitations of Usual Tools): Note HP-UX cc
10285 doesn't accept .S files.
10287 2001-11-07 Akim Demaille <akim@epita.fr>
10289 * lib/m4sugar/m4sugar.m4 (m4_pattern_forbid): Accepts $2.
10290 * lib/autoconf/general.m4 (AC_INTI): Forbid LIBOBJS.
10291 (_AC_LIBOBJ): s/LIBOBJS/LIB@&t@OBJS/.
10292 * bin/autom4te.in (warn_forbidden): New.
10293 (handle_output): Use it.
10294 Read m4_pattern_forbid with messages.
10296 2001-11-05 Akim Demaille <akim@epita.fr>
10298 * bin/autom4te.in (--normalize): Remove.
10299 * lib/autom4te.in: Adjust.
10301 2001-11-05 Akim Demaille <akim@epita.fr>
10303 * tests/Makefile.am (testsuite): Rename this target as...
10304 ($(TESTSUITE)): this.
10307 2001-11-05 Alexandre Duret-Lutz <duret_g@epita.fr>
10309 * lib/autoconf/status.m4 (_AC_OUTPUT_SUBDIRS): When removing
10310 the --prefix option, also remove it's argument.
10312 2001-11-05 Akim Demaille <akim@epita.fr>
10314 * doc/autoconf.texi (testsuite Invocation): Update.
10315 (Writing testsuite.at): Update.
10317 2001-11-03 Akim Demaille <akim@epita.fr>
10319 * doc/autoconf.texi: s/@code/@command/ where appropriate.
10321 2001-11-03 Akim Demaille <akim@epita.fr>
10323 * lib/Autom4te/General.pm: (&catfile, &canonfile)
10324 (&file_name_is_absolute): New, wrappers around routines from
10326 Use and export them.
10327 (&find_configure_ac): Optionally take a directory where to look at.
10328 * bin/autoreconf.in (&parse_args): Trim the configure.ac part of
10330 Default @ARGV to `.', not find_configure_ac.
10331 (&autoreconf): Argument is a directory.
10332 Trace AC_CONFIG_SUBDIRS and schedule the subdirs for autoreconf'ing.
10333 * doc/autoconf.texi (autoreconf Invocation): Update.
10335 2001-11-03 Akim Demaille <akim@epita.fr>
10337 * lib/Autom4te/General.pm (@export_vars, @export_subs)
10338 (@export_forward_subs): New.
10339 Add basename, dirname, and fileparse.
10341 * bin/autoreconf.in (&autoreconf): Fix call to fileparse.
10342 Don't look for aclocal flags if we already know aclocal is not
10344 Move aclocal.m4t only if it exists.
10345 Reported by Ezra Peisach.
10347 2001-11-03 Akim Demaille <akim@epita.fr>
10349 * bin/autoreconf.in (&parse_args): Work only on the configure.ac
10350 passed on command line, defaulting to ./configure.ac if present.
10351 (&maybe_autoreconf, File::Find): Remove, unused.
10352 (&autoreconf): If autoconf is not used, don't try to trace.
10354 2001-11-02 Akim Demaille <akim@epita.fr>
10356 * configure.ac: Bump to 2.52g.
10358 2001-11-02 Akim Demaille <akim@epita.fr>
10362 2001-11-02 Akim Demaille <akim@epita.fr>
10364 * config/config.guess, config/config.sub, doc/standards.texi:
10365 * config/lispdir.m4: Update from masters.
10366 * configure.ac: Bump to 2.52f.
10368 2001-11-02 Akim Demaille <akim@epita.fr>
10370 * bin/autoreconf.in (&autoreconf): Set `$aclocal_flags' to ''.
10371 Don't run aclocal when aclocal.m4 is not from aclocal.
10373 Don't run libtoolize and gettextize if --install is not given.
10375 2001-11-01 Paul Eggert <eggert@twinsun.com>
10377 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): _AS_CR_PREPARE needs to
10378 be invoked before _AS_LINENO_PREPARE.
10379 (_AS_LINENO_PREPARE): Use as_cr_digits and as_cr_alnum rather
10380 than character ranges.
10382 * lib/m4sugar/m4sh.m4 (AS_SHELL_SANITIZE): Fix NLS before
10383 invoking AS_BASENAME. Set the locale variables to 'C' if
10384 possible, as POSIX requires this to get the traditional
10386 * doc/autoconf.texi (Special Shell Variables): Describe the above.
10388 2001-10-31 Paul Eggert <eggert@twinsun.com>
10390 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): Do not surround body
10391 with {}, as that triggers a bug in Bash 2.05.
10393 (_AS_LINENO_PREPARE): Use Sed rather than
10394 Awk. Fix the sed prepass to work even if there are multiple
10395 instances of $LINENO on the same line. Do not substitute for
10396 other variables like $LINENOT. Do not check file dates; such a
10397 check is unreliable on sufficiently fast machines, and removing
10398 the check makes the code simpler and more reliable. Check for
10399 output and chmod failures.
10401 * doc/autoconf.texi (Special Shell Variables): Document
10404 2001-10-31 Akim Demaille <akim@epita.fr>
10406 * tests/Makefile.am (atconfig): Remove this target, Automake
10409 2001-10-31 Akim Demaille <akim@epita.fr>
10411 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): Do not
10412 AC_CONFIG_FILES(atlocal) as it means a file atlocal.in *must* be
10413 provided, while it is optional.
10414 * configure.ac: Adjust.
10416 2001-10-26 Paul Eggert <eggert@twinsun.com>
10418 * NEWS, README, configure.ac, lib/Autom4te/General.pm,
10419 lib/Autom4te/Struct.pm:
10420 Require Perl 5.005_03 instead of just 5.005, as some tests fail
10423 * doc/autoconf.texi (Special Shell Variables): Document some
10424 more LINENO gotchas, particularly with respect to the Awk+Sed hack.
10426 * lib/m4sugar/m4sh.m4 (_AS_LINENO_WORKS): New macro.
10427 (_AS_LINENO_PREPARE): Use it instead of shell eval, since
10428 eval $LINENO is not portable in practice.
10430 2001-10-24 Akim Demaille <akim@epita.fr>
10432 * lib/Autom4te/General.pm (backname): New.
10434 2001-10-24 Akim Demaille <akim@epita.fr>
10436 * m4/: Remove, merged into...
10439 2001-10-23 Tim Van Holder <tim.van.holder@pandora.be>
10441 * doc/autoconf.texi (Shellology): Mention the problems with bash
10442 2.05's use of ANSI quoting in its `set' builtin.
10444 2001-10-22 Paul Eggert <eggert@twinsun.com>
10446 * lib/autoconf/functions.m4 (AC_FUNC_STRERROR_R):
10447 Rename ac_cv_func_strerror_r_works to ac_cv_func_strerror_r_char_p,
10448 and rename HAVE_WORKING_STRERROR_R to STRERROR_R_CHAR_P, since
10449 POSIX decided to standardize on the int flavor of strerror_r.
10450 Always do char* test, as there's no reason not to.
10451 Assign to a char* var, to catch strerror_r that returns int*.
10453 * doc/autoconf.texi (Particular Functions):
10454 Document the above changes. Also, document the fact that
10455 AC_FUNC_STRERROR_R defines HAVE_DECL_STRERROR_R.
10457 * NEWS: Mention HAVE_WORKING_STRERROR_R -> STRERROR_R_CHAR_P.
10459 2001-10-20 Akim Demaille <akim@epita.fr>
10461 * lib/autoconf/status.m4 (_AC_OUTPUT_CONFIG_STATUS): The name of
10462 the executable was missing from the log.
10464 2001-10-20 Akim Demaille <akim@epita.fr>
10466 * lib/Autom4te/General.pm (&update_file): If destination is
10467 unchanged, remove the source.
10468 (&up_to_date_p): Don't be verbose, be debug.
10469 * bin/autoreconf.in: No longer support --m4dir.
10470 (&autoreconf): Display the full path of the configure.ac we are
10472 Trace it only once.
10473 Be sure to honor --force with gettextize.
10474 Always run aclocal.
10475 * doc/autoconf.texi: Adjust.
10477 2001-10-20 Akim Demaille <akim@epita.fr>
10479 * bin/autoheader.in ($localdir, $m4, $SIMPLE_BACKUP_SUFFIX):
10481 * bin/autoreconf.in (&autoreconf): Do not run gettextize when
10482 `intl' is already present, as it refuses unless --force.
10483 (&parse_args): Use -I, --include instead of the old Autoconf
10485 ($localdir, $autoconf_dir): Remove.
10487 (&maybe_autoreconf): New, to preserve $_ for File::Find.
10489 2001-10-19 Jens Petersen <petersen@redhat.com>
10491 * lib/autoconf/programs.m4 (AC_PROG_AWK): Prefer gawk to mawk.
10492 * doc/autoconf.texi (Particular Programs): Likewise.
10494 2001-10-19 Akim Demaille <akim@epita.fr>
10496 * lib/autoconf/status.m4 (_AC_OUTPUT_FILES): Name the generated
10497 file in @configure_input@.
10498 Don't mention `automatically' in addition to `generated'.
10499 * tests/torture.at (#define header templates): Adjust.
10501 2001-10-19 Akim Demaille <akim@epita.fr>
10503 * lib/emacs/autoconf-mode.el, lib/emacs/autotest-mode.el: In a
10504 comment, explain how to install automatic mode selection.
10507 2001-10-19 Ezra Peisach <epeisach@zif.mit.edu>
10509 * bin/autoreconf.in (autoreconf): Display the path to the
10510 configure.ac being studied.
10512 2001-10-18 Paul Eggert <eggert@twinsun.com>
10514 * lib/autoconf/types.m4 (AC_CHECK_SIZEOF): Cast sizeof to unsigned
10515 long, to work around a bug in the HP C compiler version HP92453-01
10518 * lib/m4sugar/m4sh.m4 (AS_DIRNAME): Use 'dirname' if that works.
10519 (AS_BASENAME_EXPR): New macro.
10520 (AS_BASENAME_SED): Do not assume GNU sed semantics.
10521 (AS_BASENAME): Use 'basename' if that works; then try 'expr';
10522 and fall back on 'sed' only if the other two fail. This makes
10523 AS_BASENAME act more like AS_DIRNAME.
10524 (as_me): Shell-quote the argument of AS_BASENAME, in case $0
10525 contains white space.
10526 * lib/autoconf/general.m4 (_AC_INIT_SRCDIR):
10527 Use AS_DIRNAME, since I think it's now DOS-friendly.
10528 * tests/m4sh.at (DIRNAME_TEST): New arg $3.
10529 Allow "dirname //FOO" to return either / or //, as POSIX allows
10532 2001-10-10 Akim Demaille <akim@epita.fr>
10534 * lib/autoconf/lang.m4 (_AC_COMPILER_EXEEXT_DEFAULT): Recognize
10535 `a_out.exe' for OpenVMS 7.1, DEC C 5.5 compiler, via GNV.
10538 2001-10-10 Akim Demaille <akim@epita.fr>
10540 * lib/m4sugar/m4sh.m4 (_AS_ECHO_N_PREPARE): m4_defun, not
10541 m4_define, since...
10542 (_AS_ECHO_N): AS_REQUIREs it.
10544 2001-10-10 Akim Demaille <akim@epita.fr>
10546 * lib/autoconf/general.m4 (_AC_INCLUDES_DEFAULT_REQUIREMENTS)
10547 (AC_INCLUDES_DEFAULT): Move to...
10548 * lib/autoconf/headers.m4: here.
10549 * lib/autoconf/types.m4: Comment changes.
10550 * doc/autoconf.texi: Specify where the default includes are used
10551 in the macro prototypes.
10553 2001-10-09 Akim Demaille <akim@epita.fr>

10561 (&parse_args): Pass verbosity/debugging options to subtools when
10562 --debug, not when --verbose.
10563 * lib/autom4te.in (Autoreconf-preselections): New.
10564 (Autoconf): Use it.
10566 2001-10-08 Akim Demaille <akim@epita.fr>
10568 * bin/autoreconf.in (autoreconf): Run libtoolize when appropriate.
10570 2001-10-08 Akim Demaille <akim@epita.fr>
10572 * doc/autoconf.texi (autoreconf Invocation): Adjust.
10573 * bin/autoreconf.in (autoreconf): Run gettextize when appropriate.
10575 2001-10-08 Akim Demaille <akim@epita.fr>
10577 * tests/tools.at (AT_CHECK_PERL_SYNTAX): Check autoreconf.
10578 (Syntax of the shell scripts): Don't.
10579 * bin/autoheader.in, bin/autom4te.in, bin/autoreconf.in: Don't

10979 * lib/autotest/general.m4: Englishoes.
10980 From Tim Van Holder and Alexey Mahotkin.

10984 * doc/autoconf.texi (Common Shell Constructs): New node,

10992 * lib/autoconf/general.m4 (_AC_COMPUTE_INT_COMPILE):
10993 Do not pass a first argument with leading '-'
10994 to expr, by parenthesizing initial integers that might be negative.
10996 * doc/autoconf.texi (Particular Functions): AC_FUNC_GETPGRP
10997 now merely checks whether it is an error to pass an argument
11000 * lib/autoconf/functions.m4 (_AC_FUNC_GETPGRP_TEST): Remove.
11001 (AC_FUNC_GETPGRP): Don't bother with a runtime test. Just check
11002 whether it is a (compile-time) error to pass an argument to
11003 getpgrp. This simpler test supports the revised documentation,
11004 and is all that AC_FUNC_GETPGRP's users really need.

11020 Add test for AS_BASENAME.
11021 * lib/m4sugar/m4sh.m4: Fix AS_BASENAME so that it passes the previous
11022 added test. It now correctly handles /1/2/3/, returning '3' not ''.
11023 Added AS_BASENAME_SED to make the interface the same as AS_DIRNAME.
11024 * tests/base.at: Fixed the expected responses. The old ones were
11026 * lib/autoconf/general.m4: Fixed AC_PREFIX_PROGRAM, it now behaves as
11027 the documentation claims it should (and how it behaved in 2.13).
11029 2001-09-18 Akim Demaille <akim@epita.fr>
11031 * lib/autoconf/autotest.m4 (AC_CONFIG_TESTDIR): No INIT-CMDS in

11043 Expect `package.m4' to define the package signature.

11045 * tests/Makefile.am (package.m4): New.

11073 Fix bug reported by Paul Townsend on AIX 4.3.3.0 with CFLAGS=-O4
11074 or CFLAGS=-O5. In that case, the linker has a relaxed view of
11075 fatal errors, and AC_CHECK_LIB causes it to include libraries even
11076 when they don't exist.
11078 * lib/autoconf/headers.m4 (AC_HEADER_DIRENT): Use AC_SEARCH_LIBS,
11079 not AC_CHECK_LIB, so that we don't use -ldir or -lx if we don't

11083 version with the version used by fileutils 4.1, except use

11129 * lib/autotest/general.m4 (AT_INIT): Create and remove

11234 to avoid GCC warnings.
11237 2001-09-05 Akim Demaille <akim@epita.fr>

11241 2001-09-05 Akim Demaille <akim@epita.fr>
11243 Be ready to handle filenames as stupid as `dnl.at', for if even
11244 the maintainer is dumb enough to do that...
11246 * lib/autotest/general.m4 (AT_SETUP, AT_LINE): Demonstrates your
11247 excellence in M4 quotation: consider `__file__' is active.
11249 And BTW, when invoking m4, pass the --include in the right order:

11314 * doc/autoconf.texi (Quadrigraphs): Document `@&t@'.
11315 (testsuite Scripts): There is no such thing as `atconfig.in'.

11320 * lib/Autom4te/General.pm (&find_file): Browse the includes in the
11323 2001-08-31 Akim Demaille <akim@epita.fr>

11398 Map --localdir, --autoconf-dir onto it.
11399 Forward autom4te's options instead of interpreting them.

11423 * lib/Autom4te/General.pm (&find_peer): Remove.
11424 * lib/autotest/general.m4 (AT_INIT): `AUTOTEST_PATH=a:b' gives

11426 * man/Makefile.am: Let help2man rely on PATH instead of trying to
11427 find the executables for it.
11428 * tests/Makefile.am: Major cleanup. Too lazy to document...
11429 * tests/atlocal.in: Remove all the obscure envvar manipulations.
11431 * tests/atspecific.m4, tests/tools.at: Passing --localdir is
11432 indeed related to running the test suite, while passing
11433 --autoconf-dir and others is related to running non installed
11434 Autoconf executables. So don't do that, leave it to...

11436 * tests/autoscan: New.
11437 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): Don't

11454 Suggested by Paul Eggert.
11456 2001-08-29 Akim Demaille <akim@epita.fr>
11458 * Makefile.maint (do-po-update): Wget refuses to overwrite files:
11459 download in a tmp dir.
11461 2001-08-29 Akim Demaille <akim@epita.fr>

12000 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12002 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Handle ACTION-IF-TRUE,
12003 ACTION-IF-FALSE, and ACTION-IF-UNKNOWN.
12004 * doc/autoconf.texi (C Compiler Characteristics): Update
12005 documentation for AC_C_BIGENDIAN.
12007 2001-08-11 Alexandre Duret-Lutz <duret_g@epita.fr>
12009 * lib/autoconf/c.m4 (AC_C_BIGENDIAN): Guess endianness by grep'ing
12010 magic values from an object file when cross-compiling.
12011 Based on code by Guido Draheim <Guido.Draheim@gmx.de>.
12013 2001-08-10 Akim Demaille <akim@epita.fr>
12015 * bin/autom4te.in (&handle_output): Don't use `grep' with side
12017 Suggested by Russ Allbery.
12019 2001-08-10 Ralf Corsepius <corsepiu@faw.uni-ulm.de>
12021 * lib/autoconf/general.m4 (_AC_OUTPUT_SUBDIRS): Propagate the
12022 current $prefix to the sub-configures.
12024 2001-08-09 Tim Van Holder <tim.van.holder@pandora.be>
12026 * lib/autoconf/lang.m4: Ignore *.xSYM when looking for an executable
12027 extension (needed on BeOS). Reported by Guido van Rossum.
12029 2001-08-09 Akim Demaille <akim@epita.fr>
12031 * bin/autom4te.in ($icache): Load it only if older than autom4te.
12033 2001-08-07 Akim Demaille <akim@epita.fr>
12035 * lib/autotest/general.m4 (AT_INIT): All the `at-*' are to be
12037 (at-setup-line): Huh? Be a variable `at_setup_line', not a file.
12038 No need to remove the files before and after the each test, before
12039 each test and at the end of the suite is enough.
12040 Display only the children `times', not the shell's.
12041 If the test failed or was skipped, at-times is not available.
12043 2001-08-07 Akim Demaille <akim@epita.fr>
12045 Always produce testsuite.log, including when there are no
12046 failures. This helps getting information on skipped tests, and
12047 duration of the tests. Err, implement the latter btw.
12049 * lib/autotest/general.m4 (AT_INIT): Set up fd 6 for the log.
12050 Dump information on the first run of each test.
12051 (AT_CLEANUP): Create `at-times' containing the duration of the
12054 2001-08-07 Akim Demaille <akim@epita.fr>
12056 The use of `dumpstat' revealed that `len' was used although it
12057 should not. m4_text_wrap was using it, but in the Autoconf world
12058 where it is legal. Hence (i) test M4sh in its own world, not
12059 Autoconf's, and (ii), ahem, fix the bug :)
12061 * lib/autotest/general.m4: Be sure the set good quotes, as tracing
12062 does not like `' instead of [].
12063 (AT_INIT): Forbid `^_?AT_'.
12064 And don't output such tokens.
12065 * tests/Makefile.am (CLEANFILES): Add `script', `script.s4g',
12066 `script.as', and `autom4te.cache'.
12067 Remove `empty' and `macro' which are no longer used.
12068 * tests/atspecific.m4 (AT_CHECK_M4SUGAR, AT_CHECK_M4SH): New.
12069 * tests/m4sugar.at: Use it.
12070 * lib/m4sugar/m4sugar.m4: Use `m4_len' not `len'.
12072 2001-08-07 Akim Demaille <akim@epita.fr>
12074 * bin/autoconf.in, bin/autoheader.in: --force, -f is a new option.
12076 2001-08-07 Alexandre Duret-Lutz <duret_g@epita.fr>
12078 * bin/autom4te.in (handle_output): Typo in quadrigraph substitution.
12080 2001-08-04 Akim Demaille <akim@epita.fr>
12082 * lib/autoconf/functions.m4 (AC_FUNC_ALLOCA, AC_FUNC_ERROR_AT_LINE)
12083 (AC_FUNC_FSEEKO, AC_FUNC_OBSTACK): Use AC_LANG_IFELSE, not
12085 * lib/autoconf/headers.m4 (AC_HEADER_MAJOR): Likewise.
12086 * lib/autoconf/fortran.m4 (_AC_LANG_PROGRAM_C_F77_HOOKS)
12087 (AC_F77_MAIN): Likewise.
12089 2001-08-04 Akim Demaille <akim@epita.fr>
12091 Don't rely on M4sugar outputting the patterns in files, since we
12092 might process the output _without_ running m4, hence without these
12095 * lib/m4sugar/m4sugar.m4 (m4_init): No need for `m4_tmpdir'.
12096 * bin/autom4te.in (@Request::includes): Remove, unused.
12097 (@Request::source): Rename as...
12098 (@Request::input): this.
12099 (@preselect): Add `m4_pattern_forbid' and `m4_pattern_allow'.
12100 (&handle_output): Fetch the patterns from the traces.
12101 `$forbidden' and `$allowed' are constant: use m//o.
12102 (&handle_m4): M4sugar no longer wants `m4_tmpdir'.
12103 (m4_pattern_forbid, m4_pattern_allow): Adjust for tracing only.
12105 2001-08-04 Akim Demaille <akim@epita.fr>
12107 `autoconf && autoheader' is sped up. Now, speed up `autoheader &&
12108 autoconf', i.e., in addition to caching traces, cache the output.
12110 * bin/autom4te.in (Request::cache): Rename as...
12111 (Request::id): this.
12112 ($cache, $icache, $tcache, $ocache): New.
12113 (&handle_m4): Save M4 output in the cache instead of $tmp.
12114 (&handle_output): Adjust.
12115 (&up_to_date_p): Check that the output cache is up to date too.
12116 (top level): Run `&handle_m4' iff force or the cache is invalid.

12119 2001-08-04 Akim Demaille <akim@epita.fr>
12121 * bin/autom4te.in ($force): New.
12122 (&parse_args, &print_usage): -f, --force is a new option.
12123 (&handle_output): CPP directives might have spaces after `#'.
12124 (&parse_args): The first file only can be frozen.
12126 2001-08-04 Akim Demaille <akim@epita.fr>
12128 Don't let autom4te compute the `include' traces several times:
12129 first check that the trace cache file is up to date, and then
12130 compare its timestamp with that of the output.
12132 * bin/autom4te.in, bin/autoupdate.in, bin/autoscan.in: Normalize
12133 the preamble. Don't require 5.005 as Autom4te::General does it,
12134 and better yet (use `use', not `require'!).
12135 * lib/Autom4te/Struct.pm: Rename the last occurrences of
12136 Class::Struct as Autom4te::Struct.
12137 * lib/Autom4te/General.pm (File::stat): Use it.
12138 (&mtime): New, export it.
12139 * bin/autom4te.in: Use it.
12140 Declare `$req' is invalid if it is outdated.
12141 Don't declare it valid before saving it if something went wrong.
12143 2001-08-04 Akim Demaille <akim@epita.fr>
12145 Autom4te shall not encode Autoconf data, and preselecting traces
12146 must be proposed to the users.
12148 * bin/autom4te.in (@required_trace): Remove.
12150 (&parse_args, &print_usage): -p, --preselect is a new option.
12151 (&up_to_date_p): Adjust.

12156 * tests/tools.at (autoconf --trace: user macros): Check traces on
12157 macros invoked without arguments, and macros invoked with multiple
12160 2001-08-03 Alexandre Duret-Lutz <duret_g@epita.fr>
12162 * bin/autom4te.in (handle_traces): Fix rewriting of traces without
12165 2001-08-03 Akim Demaille <akim@epita.fr>
12167 * bin/autoconf.in ($@): Work around the usual sh bug.
12170 2001-08-03 Akim Demaille <akim@epita.fr>
12172 Clean up the handling of the M4 builtins tracing exception.
12174 * bin/autom4te.in (Request::request): Don't complete M4 builtins

12177 (@m4_builtin): this.
12178 (%m4_builtin_alternate_name): New.
12179 (&parse_args): Complete the trace requests with alternate names.

12191 (m4_divert_pop): Dump the whole diversion stack when a diversion
12193 * bin/autom4te.in (&handle_output): Remember of the first
12194 occurrence of a possibly undefined macro, not the last.
12195 Complain about the possibly undefined macros in the same order as
12196 the appear in the output.
12197 * lib/autoconf/Makefile.am (autoconf.m4f): List its dependencies.
12198 * tests/tools.at (autoconf: forbidden tokens, basic)
12199 (autoconf: forbidden tokens, exceptions): No longer sort
12200 autoconf's stderr, as it is now deterministic.
12201 Check that `dnl' is caught.
12203 2001-08-01 Akim Demaille <akim@epita.fr>
12205 * configure.ac: Bump to 2.52c.

12222 * bin/autoconf.in, bin/autom4te.in, bin/autoupdate.in: Remove your
12223 `END', as `Autom4te::General::END' will be triggered.
12224 * bin/autoupdate.in, bin/autoscan.in: Improve error messages accuracy.
12225 * bin/autoupdate.in (File::Compare, File::Copy): Use them instead of
12226 system to run `mv', `rm', and `cmp'.
