3 - The rebuild rules for distributed Yacc and Lex output will avoid
4 overwriting existing files if AM_MAINTAINER_MODE and maintainer-mode
9 * Makefile.in bloat reduction:
11 - Inference rules are used to compile sources in subdirectories when
12 the `subdir-objects' option is used and no per-target flags are
13 used. This should reduce the size of some projects a lot, because
14 Automake used to output an explicit rule for each such object in
17 - Automake no longer outputs three rules (.o, .obj, .lo) for each
18 object that must be built with explicit rules. It just outputs
19 the rules required to build the kind of object considered: either
20 the two .o and .obj rules for usual objects, or the .lo rule for
23 * Change to Libtool support:
25 - Libtool tags are used with libtool versions that support them.
26 (I.e., with Libtool 1.5 or greater.)
28 - Automake is now able to handle setups where a libtool library is
29 conditionally installed in different directories, as in
32 lib_LTLIBRARIES = liba.la
34 pkglib_LTLIBRARIES = liba.la
40 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
41 really evaluated, before it decides to include them in aclocal.m4.
42 This solves nasty problems with conditional redefinitions of
43 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
44 *.m4 files to be included in any project using these macros.
45 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
46 most famous instance of this bug.)
48 - Do not complain about missing conditionally AC_REQUIREd macros
49 that are not actually used. In 1.8.x aclocal would correctly
50 determine which of these macros were really needed (and include
51 only these in the package); unfortunately it would also require
52 all of them to be present in order to run. This created
53 situations were aclocal would not work on a tarball distributing
54 all the macros it uses. For instance running aclocal on a project
55 containing only the subset of the Gettext macros in use by the
56 project did not work, because gettext conditionally requires other
59 * Portability improvements:
61 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
62 tar-pax. The new option filename-length-max=99 helps diagnosing
63 filenames that are too long for tar-v7. (PR/414)
65 - Variables aumented with `+=' are now automatically flattened (i.e.,
66 trailing backslashes removed) and then wrapped around 80 colummns
67 (adding trailing backslashes). In previous versions, a long series
73 would result in a single-line definition of VAR that could possibly
74 exceed the maximum line length of some make implementations.
76 Non-augmented variables are still output as they are defined in
81 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
82 Works the same as the old Fortran 77 implementation; just replace
83 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
84 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
86 - Support for conditional _LISP.
88 - Support for conditional -hook and -local rules (PR/428).
90 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
92 - Automake will not write any Makefile.ins after the first error it
93 encounters. The previous Makefile.ins (if any) will be left in
94 place. (Warnings will not prevent output, but remember they can
95 be turned into errors with -Werror.)
97 - The restriction that SUBDIRS must contain direct children is gone.
100 - The manual tells more about SUBDIRS vs. DIST_SUBDIRS.
101 It also gives an example of nested packages using AC_CONFIG_SUBDIRS.
105 * Long standing bugs:
107 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
108 so that `make distclean' and `make maintainer-clean' can work.
110 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
112 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
114 - Polish diagnostic when no input file is found.
118 * Long standing bugs:
120 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
121 overridden by the user.
123 - Honor PATH_SEPARATOR in various places of the Automake package, for
126 - Adjust dependency tracking mode detection to ICC 8.0's new output.
129 - Fix install-sh so it can install the `mv' binary... using `mv'.
131 - Fix tru64 dependency tracking for libtool objects.
133 - Work around Exuberant Ctags when creating a TAGS files in a directory
134 without files to scan but with subdirectories to include.
136 * Bugs introduced by 1.8:
138 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
139 not defined in the same conditions as the _LDADD that uses it.
141 - Do not warn when JAVAROOT is overridden, this is legitimate.
145 * Long standing bugs:
147 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
148 or any of the other *dir variables contain a space.
150 Please note that Automake does not and cannot support spaces in
151 filenames that are involved during the build. This change affects
152 only installation paths, so that `make install' does not bomb out
153 in packages configured with
154 ./configure --prefix '/c/Program Files'
156 - Fix the depfiles output so it works with GNU sed (<4.1) even when
157 POSIXLY_CORRECT is set.
159 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
160 since Autoconf 2.54, which defines LIBOBJS itself.
162 - Fix a potential (but unlikely) race condition in parallel elisp
163 builds. (Introduced in 1.7.3.)
165 - Do not assume that users override _DEPENDENCIES in all conditions
166 where Automake will try to define them.
168 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
169 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
172 This fix also affects the $(mkdir_p) variable defined since
173 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
174 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
176 - Secure temporary directory creation in `make distcheck'. (PR/413)
178 - Do not generate two build rules for `parser.h' when the
179 parser appears in two different conditionals.
181 - Work around a Solaris 8 /bin/sh bug in the test for dependency
182 checking. Usually ./configure will not pick this shell; so this
183 fix only helps cases where the shell is forced to /bin/sh.
185 * Bugs introduced by 1.8:
187 - In some situations (hand-written `m4_include's), aclocal would
188 call the `File::Spec->rel2abs' method, which was only introduced
189 in Perl 5.6. This new version reestablish support Perl 5.005.
191 It is likely that the next major Automake releases will require at
192 least Perl 5.6. Consider upgrading your development environment
193 if you are still using the five-year-old Perl 5.005.
195 - Automake would sometimes fail to define rules for targets listed
196 in variables defined in multiple conditions. For instance on
202 it would define only the `a.$(OBJEXT): a.c' rule and omit the
203 `b.$(OBJEXT): b.c' rule.
205 * New sections in manual:
207 - Third-Party Makefiles: how to interface third party Makefiles.
208 - Upgrading: upgrading packages to newer Automake versions.
209 - Multiple Outputs: handling tools that produce many outputs.
213 * A (well known) portability bug slipped in the changes made to
214 install-sh in Automake 1.8.1. The broken install-sh would refuse to
215 install anything on Tru64.
217 * Fix install rules for conditionally built python files. (This never
222 * Bugs introduced by 1.8:
224 - Fix Config.pm import error with old Perl versions (at least
225 5.005_03). One symptom is that aclocal could not find its macro
228 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
229 created by `make install' are always world readable, even if the
230 installer happens to have an overly restrictive umask (e.g. 077).
231 This was a mistake and has been reverted. There are at least two
232 reasons why we must not use `-m 0755':
233 - it causes special bits like SGID to be ignored,
234 - it may be too restrictive (some setups expect 775 directories).
236 - Fix aclocal to honor definitions located in files which have been
237 m4_included manually. aclocal 1.8 had been updated to check
238 m4_included files for new requirements, but forgot that these
239 m4_included files can also provide new definitions.
241 Note that if you have such a setup, we recommend you get rid of
242 it. In the past, there was a reason to m4_include files manually:
243 aclocal used to duplicate entire M4 files into aclocal.m4, even
244 files that were distributed. Some packages were therefore
245 m4_including the distributed file directly, and playing some
246 tricks to ensure aclocal would not copy that file to aclocal.m4,
247 in order to limit the amount of duplication. Since aclocal 1.8.x
248 will precisely output m4_includes for local M4 files, we recommend
249 that you clean up your setup, removing all manual m4_includes and
250 letting aclocal output them.
252 - Output detailed menus in the Info version if the Automake manual,
253 so that Emacs can locate the indexes.
255 - configure.ac and configure were listed twice in DIST_COMMON (an
256 internal variable where Automake lists configury files to
257 distribute). This was harmless, but unaesthetic.
259 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
260 This was an issue only in the Automake package itself, not in
263 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
264 DEST:SRC. This was wrong, as some packages do
265 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
268 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
269 argument. This caused two kinds of failures:
270 - Rules installing data in a conditionally defined directory
271 failed when that directory was undefined. In this case no
272 argument was supplied.
273 - `make installdirs' failed, because several directories were
274 passed to $(mkdir_p). This was an issue only on platform
275 were $(mkdir_p) is implemented with `install-sh -d'.
276 $(mkdir_p) as been changed to accept 0 or more arguments, as
279 * Long-standing bugs:
281 - Fix an unexpected diagnostic occurring when users attempt
282 to override some internal variables that Automake appends to.
284 - aclocal now scans configure.ac for macro definitions (PR/319).
286 - Fix a portability issue with OSF1/Tru64 Make. If a directory
287 distributes files which are outside itself (this usually occurs
288 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
289 from a parent package), then `make distcheck' fails due to an
290 optimization performed by OSF1/Tru64 Make in its VPATH handling.
291 (tests/subpkg2.test failure)
293 - Fix another portability issue with Sun and OSF1/Tru64 Make.
294 In a VPATH-build configuration, `make install' would install
295 nobase_ files to wrong locations.
297 - Fix a Perl `uninitialized value' diagnostic occurring when
298 automake complains that a Texinfo file does not have a
299 @setfilename statement.
301 - Erase config.status.lineno during `make distclean'. This file
302 can be created by config.status. Automake already knew about
303 configure.lineno, but forgot config.status.lineno.
305 - Distribute all files, even those which are built and installed
306 conditionally. This change affects files listed in conditionally
307 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
308 as well as those listed in conditionally defined dist_*_DATA,
309 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
311 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
312 doesn't conform to POSIX.
314 - Normalize help strings for configure variables and options added
319 - Check for python2.4 in AM_PATH_PYTHON.
321 * Spurious failures in test suite:
323 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
324 tests/ltconv.test: fix failures with CVS Libtool.
325 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
326 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
327 fix failures with old Texinfo versions.
333 - The NEWS file is more verbose.
337 - Autoconf 2.58 or greater is required.
341 - Default source file names in the absence of a _SOURCES declaration
342 are made by removing any target extension before appending `.c', so
343 to make the libtool module `foo.la' from `foo.c', you only need to
346 lib_LTLIBRARIES = foo.la
347 foo_la_LDFLAGS = -module
349 For backward compatibility, foo_la.c will be used instead of
350 foo.c if this file exists or is the explicit target of a rule.
351 However -Wobsolete will warn about this deprecated naming.
353 - AR's `cru' flags are now set in a global ARFLAGS variable instead
354 of being hard-coded in each $(AR) invocation, so they can be
355 substituted from configure.ac. This has been requested by people
356 dealing with non-POSIX ar implementations.
358 - New warning option: -Woverride. This will warn about any user
359 target or variable definitions which override Automake
362 - Texinfo rules back up and restore info files when makeinfo fails.
364 - Texinfo rules now support the `html' target.
365 Running this requires Texinfo 4.0 or greater.
367 `html' is a new recursive target, so if your package mixes
368 hand-crafted `Makefile.in's with Automake-generated
369 `Makefile.in's, you should adjust the former to support (or
370 ignore) this target so that `make html' recurses successfully. If
371 you had a custom `html' rule in your `Makefile.am', it's better to
372 rename it as `html-local', otherwise your rule will override
373 Automake's new rule (you can check that by running `automake
374 -Woverride') and that will stop the recursion to subdirectories.
376 Last but not least, this `html' rule is declared PHONY, even when
377 overridden. Fortunately, it appears that few packages use a
378 non-PHONY `html' rule.
380 - Any file which is m4_included from configure.ac will appear as a
381 configure and Makefile.in dependency, and will be automatically
384 - The rules for rebuilding Makefiles and Makefile.ins will now
385 rebuild all Makefiles and all Makefile.ins at once when one of
386 configure's dependencies has changed. This is considerably faster
387 than previous implementations, where config.status and automake
388 were run separately in each directory (this still happens when you
389 change a Makefile.am locally, without touching configure.ac or
390 friends). Doing this also solves a longstanding issue: these
391 rebuild rules failed to work when adding new directories to the
392 tree, forcing you to run automake manually.
394 - For similar reasons, the rules to rebuild configure,
395 config.status, and aclocal.m4 are now defined in all directories.
396 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
397 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
398 should better define them in all directories. This is easily done
399 using an AC_SUBST (make sure you prefix these dependencies with
400 $(top_srcdir) since this variable will appear at different
401 levels of the build tree).
403 - aclocal will now use `m4_include' instead of copying local m4
404 files into aclocal.m4. (Local m4 files are those you ship with
405 your project, other files will be copied as usual.)
407 Because m4_included files are automatically distributed, it means
408 for most projects there is no point in EXTRA_DISTing the list of
409 m4 files which are used. (You can probably get rid of
410 m4/Makefile.am if you had one.)
412 - aclocal will avoid touching aclocal.m4 when possible, so that
413 Autom4te's cache isn't needlessly invalidated. This behavior can
414 be switched off with the new `--force' option.
416 - aclocal now uses Autoconf's --trace to detect macros which are
417 actually used and will no longer include unused macros simply
418 because they where mentioned. This was often the case for macros
419 called conditionally.
421 - New options no-dist and no-dist-gzip.
423 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
424 py-compile, and ylwrap, now all understand --version and --help.
426 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
427 links as part of the distclean target and including source files in
430 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
431 argument. The latter can be used to override the default behavior
434 - Automake will exit with $? = 63 on version mismatch. (So does
435 Autoconf 2.58) missing knows this, and in this case it will
436 emulate the tools as if they were absent. Because older versions
437 of Automake and Autoconf did not use this exit code, this change
438 will only be useful in projects generated with future versions of
441 - When using AC_CONFIG_FILES with multiple input files, Automake
442 generates the first ".in" input file for which a ".am" exists.
443 (Former versions would try to use only the first input file.)
445 - lisp_DATA is now allowed. If you are using the empty ELCFILES
446 idiom to disable byte-compilation of lisp_LISP files, it is
447 recommended that you switch to using lisp_DATA. Note that
448 this is not strictly equivalent: lisp_DATA will install elisp
449 files even if emacs is not installed, while *_LISP do not
450 install anything unless emacs is found.
452 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
453 available. This selection is achieved through the Makefile
454 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
455 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
456 `$(install_sh) -m 0755 -d'.
460 - Because `mkdir -p' is available on most platforms, and we can use
461 `install-sh -d' when it is not, the use of the mkinstalldirs
462 script is being phased out. `automake --add-missing' no longer
463 installs it, and if you remove mkinstalldirs from your package,
464 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
466 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
467 gettextize and autopoint will install it when needed. Automake
468 will continue to define the $(mkinstalldirs) and to distribute
469 mkinstalldirs when this script is in the source tree.
471 - AM_PROG_CC_STDC is now empty. The content of this macro was
472 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
473 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
474 renaming should be safe, even if you have to support several,
475 versions of Automake, because AC_PROG_CC defines this variable
476 since Autoconf 2.54.)
478 - Some users where using the undocumented ACLOCAL_M4_SOURCES
479 variable to override the aclocal.m4 dependencies computed
480 (inaccurately) by older versions of Automake. Because Automake
481 now tracks configure's m4 dependencies accurately (see m4_include
482 above), the use of ACLOCAL_M4_SOURCES should be considered
483 obsolete and will be flagged as such when running `automake
488 - Defining programs conditionally using Automake conditionals no
489 longer leads to a combinatorial explosion. The following
490 construct used to be troublesome when used with dozens of
505 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
507 - Due to implementation constraints, previous versions of Automake
508 proscribed multiple conditional definitions of some variables
518 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
519 This restriction has been lifted, and these variables now
520 support multiple conditional definitions as do other variables.
522 - Cleanup the definitions of $(distdir) and $(top_distdir).
523 $(top_distdir) now points to the root of the distribution
524 directory created during `make dist', as it did in Automake 1.4,
525 not to the root of the build tree as it did in intervening
526 versions. Furthermore these two variables are now only defined in
527 the top level Makefile, and passed to sub-directories when running
530 - The --no-force option now correctly checks the Makefile.in's
531 dependencies before deciding not to update it.
533 - Do not assume that make files are called Makefile in cleaning rules.
535 - Update .info files in the source tree, not in the build tree. This
536 is what the GNU Coding Standard recommend. Only Automake 1.7.x
537 used to update these files in the build tree (previous versions did
538 it in the source tree too), and it caused several problems, varying
539 from mere annoyance to portability issues.
541 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
542 when --add-missing and --force-missing are used. For backward
543 compatibility --add-missing will continue to install COPYING (in
544 `gnu' strictness) when none of these three files exist, but this
545 use is deprecated: you should better choose a license yourself and
546 install it once for all in your source tree (and in your code
549 - Fix ylwrap so that it does not overwrite header files that haven't
550 changed, as the inline rule already does.
552 - User-defined rules override automake-defined rules for the same
553 targets, even when rules do not have commands. This is not new
554 (and was documented), however some of the automake-generated
555 rules have escaped this principle in former Automake versions.
556 Rules for the following targets are affected by this fix:
558 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
559 info, info-am, install-data-am, install-exec-am, install-info,
560 install-info-am, install-man, installcheck-am, maintainer-clean,
561 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
562 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
564 Practically it means that an attempt to supplement the dependencies
565 of some target, as in
569 will now *silently override* the automake definition of the
570 rule for this target. Running `automake -Woverride' will diagnose
571 all such overriding definitions.
573 It should be noted that almost all these targets support a *-local
574 variant that is meant to supplement the automake-defined rule
575 (See node `Extending' in the manual). The above rule should
578 clean-local: my-clean-rule
580 These *-local targets have been documented since at least
581 Automake 1.2, so you should not fear the change if you have
582 to support multiple automake versions.
586 - The Automake manual is now distributed under the terms of the GNU FDL.
588 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
590 - core dumps are no longer removed by the cleaning rules. There are
591 at least three reasons for this:
592 1. These files should not be created by any build step,
593 so their removal do not fit any of the cleaning rules.
594 Actually, they may be precious to the developer.
595 2. If such file is created during a build, then it's clearly a
596 bug Automake should not hide. Not removing the file will
597 cause `make distcheck' to complain about its presence.
598 3. Operating systems have different naming conventions for
599 core dump files. A core file on one system might be a
600 completely legitimate data file on another system.
602 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
603 defined by Automake. This means that any definition in the
604 environment will be used, unless overridden in the Makefile.am or
605 on the command line. The old behavior, where these variables were
606 defined empty in each Makefile, can be obtained by AC_SUBSTing or
607 AC_ARG_VARing each variable from configure.ac.
609 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
610 documented. (The is not a new feature, these variables have
611 been there since at least Automake 1.4.)
614 * Fix install-strip to work with nobase_ binaries.
615 * Fix renaming of #line directives in ylwrap.
616 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
619 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
620 * Fix detection of Debian's install-info, broken since version 1.5.
621 (Debian bug #213524).
622 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
623 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
626 * The implementation of automake's --no-force option is unreliable,
627 so this option is ignored in this version. A real fix will appear in
628 Automake 1.8. (Debian Bug #206299)
629 * AM_PATH_PYTHON: really check the whole list of interpreters if no
630 argument is given. (PR/399)
631 * Do not warn about leading `_' in variable names, even with -Wportability.
632 * Support user redefinitions of TEXINFO_TEX.
633 * depcomp: support AIX Compiler version 6.
634 * Fix missing rebuilds during `make dist' with BSD make.
635 (Could produce tarballs containing out-of-date files.)
636 * Resurrect multilib support.
637 * Noteworthy manual updates:
638 - Extending aclocal: how to write m4 macros that won't trigger warnings
640 - A Shared Library: Rewrite and split into subsections.
643 * Fix depcomp's icc mode for ICC 7.1.
644 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
645 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
646 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
647 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
648 * Remove Latin-1 characters from elisp-comp.

673 * Minor documentation fixes.
676 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
677 * Query distutils for `pythondir' and `pythonexecdir', instead of
678 using an hardcoded path. This should allow builds on 64-bit
679 distributions that usually use lib64/ instead of lib/.
680 * AM_PATH_PYTHON will also search for python2.3.
681 * elisp files are now built all at once instead of one by one. Besides
682 incurring a speed-up, this is required to support interdependent elisp files.
684 - `make distcheck' will now work in `_inst/' and `_build' instead
685 of `=inst/' and `=build/'

695 - makedepend mode: work with Libtool. (PR/385 too)
697 * better support for unusual gettext setups, such as multiple po/ directories
699 - Flag missing po/ and intl/ directories as warnings, not errors.

710 if AM_GNU_GETTEXT([external]) is used.
711 * Correctly uninstall renamed man pages.
712 * Do not strip escaped newline in variables defined in one condition
713 and augmented in another condition.
714 * Fix ansi2knr rules for LIBOBJS sources.
715 * Clean all known Texinfo index files, not only those which appear to
716 be used, because we cannot know wich indexes are used in included files.
717 (PR/375, Debian Bug #168671)
718 * Honor only the first @setfilename seen in a Texinfo file.
719 * Treat "required file X not found" diagnostics as errors (exit status 1).

722 * Don't use single suffix inference rules when building `.info'-less
723 Info files, for the sake of Solaris make.

725 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
726 * Warn about multiple inference rules when -Wportability is used. (PR/372)
727 * Fix building of deansified files from subdirectories. (PR/370)
728 * Add missing `fi' in the .c->.obj rules.
729 * Improve install-sh to work even when names contain spaces or certain
730 (but not all) shell metachars.
731 * Fix the following spurious failures in the test suite:
732 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
733 * Noteworthy manual updates:
734 - Augment the section about BUILT_SOURCES.
735 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
738 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
740 * Aclocal should now recognize macro names containing parentheses, e.g.
741 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
742 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
744 * Install Python files even if they were built. (PR/369)
745 * Have stamp-vti dependent upon configure instead of configure.ac, as the
746 version might not be defined in the latter. (PR/358)
747 * Reorder arguments passed to a couple of commands, so things works
748 when POSIXLY_CORRECT=1.
749 * Fix a regex that can cause Perl to segfault on large input.
751 * Fix distribution of packages that have some sources defined conditionally,
752 as in the `Conditional compilation using Automake conditionals' example
754 * Fix spurious test suite failures on IRIX.
755 * Don't report a required variable as undefined if it has been
756 defined conditionally for the "right" conditions.
757 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
758 `make distcheck' fails.
759 * Fix distribution of included Makefile fragment, so we don't create
760 spurious directories in the distribution. (PR/366)
761 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
764 * Autoconf 2.54 is required.
765 * `aclocal' and `automake' will no longer warn about obsolete
766 configure macros. This is done by `autoconf -Wobsolete'.
767 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
768 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
769 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
770 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
771 `configure.ac' for you.
772 * Support for per-program and per-library `_CPPFLAGS'.
773 * New `ctags' target (builds CTAGS files).
774 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
775 (see `automake --help' or the manual for a list of them).
776 * Honor the WARNINGS environment variable.
777 * Omit the call to depcomp when using gcc3: call the compiler directly.

786 * `+=' can be used in conditionals, even if the augmented variable
787 was defined for another condition.
788 * Makefile fragments (inserted with `include') are always distributed.
789 * Use Autoconf's --trace interface to inspect configure.ac and get
790 a more accurate view of it.
791 * Add support for extending aclocal's default macro search path
792 using a `dirlist' file within the aclocal directory.
793 * automake --output-dir is deprecated.
794 * The part of the distcheck target that checks whether uninstall actually
795 removes all installed files has been moved in a separate target,
796 distuninstallcheck, so it can be overridden easily.
800 * Support for AM_INIT_GETTEXT([external])
801 * Bug fixes, including:
802 - Fix Automake's own `make install' so it works even if `ln' doesn't.
803 - nobase_ programs and scripts honor --program-transform correctly.
804 - Erase configure.lineno during `make distclean'.

823 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
824 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
827 * Autoconf 2.52 is required.
828 * automake no longer run libtoolize.
829 This is the job of autoreconf (from GNU Autoconf).
830 * `dist' generates all the archive flavors, as did `dist-all'.
831 * `dist-gzip' generates the Gzip tar file only.
832 * Combining Automake Makefile conditionals no longer lead to a combinatorial
833 explosion. Makefile.in's keep a reasonable size.
834 * AM_FUNC_ERROR_AT_LINE, AM_FUNC_STRTOD, AM_FUNC_OBSTACK, AM_PTRDIFF_T
835 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
837 * `#line' of Lex and Yacc files are properly set.
838 * EXTRA_DIST can contain generated directories.
839 * Support for dot-less extensions in suffix rules.
840 * The part of the distcheck target that checks whether distclean actually

850 * `AC_INIT AM_INIT_AUTOMAKE(tarname,version)' is an obsolete construct.
851 You can now use `AC_INIT(pkgname,version) AM_INIT_AUTOMAKE' instead.
852 (Note that "pkgname" is not "tarname", see the manual for details.)
853 It is also possible to pass a list of global Automake options as
854 first argument to this new form of AM_INIT_AUTOMAKE.
855 * Compiler-based assembler is now called `CCAS'; people expected `AS'
856 to be a real assembler.
857 * AM_INIT_AUTOMAKE will set STRIP itself when it needs it. Adding
858 AC_CHECK_TOOL([STRIP], [strip]) manually is no longer required.
859 * aclocal and automake are also installed with the version number
860 appended, and some of the install directory names have changed.
