3 * Makefile.in bloat reduction:
5 - Inference rules are used to compile sources in subdirectories when
6 the `subdir-objects' option is used and no per-target flags are
7 used. This should reduce the size of some projects a lot, because
8 Automake used to output an explicit rule for each such object in
11 - Automake no longer outputs three rules (.o, .obj, .lo) for each
12 object that must be built with explicit rules. It just outputs
13 the rules required to build the kind of object considered: either
14 the two .o and .obj rules for usual objects, or the .lo rule for
17 * Change to Libtool support:
19 - Libtool tags are used with libtool versions that support them.
20 (I.e., with Libtool 1.5 or greater.)
22 - Automake is now able to handle setups where a libtool library is
23 conditionally installed in different directories, as in
26 lib_LTLIBRARIES = liba.la
28 pkglib_LTLIBRARIES = liba.la
34 - aclocal now ensures that AC_DEFUNs and AU_DEFUNs it discovers are
35 really evaluated, before it decides to include them in aclocal.m4.
36 This solves nasty problems with conditional redefinitions of
37 Autoconf macros in /usr/share/aclocal/*.m4 files causing extraneous
38 *.m4 files to be included in any project using these macros.
39 (Calls to AC_PROG_EGREP causing libtool.m4 to be included is the
40 most famous instance of this bug.)
42 - Do not complain about missing conditionally AC_REQUIREd macros
43 that are not actually used. In 1.8.x aclocal would correctly
44 determine which of these macros were really needed (and include
45 only these in the package); unfortunately it would also require
46 all of them to be present in order to run. This created
47 situations were aclocal would not work on a tarball distributing
48 all the macros it uses. For instance running aclocal on a project
49 containing only the subset of the Gettext macros in use by the
50 project did not work, because gettext conditionally requires other
53 * Portability improvement:
55 - Tar format can be chosen with the new options tar-v7, tar-ustar, and
56 tar-pax. The new option filename-length-max=99 helps diagnosing
57 filenames that are too long for tar-v7. (PR/414)
59 - Variables aumented with `+=' are now automatically flattened (i.e.,
60 trailing backslashes removed) and then wrapped around 80 colummns
61 (adding trailing backslashes). In previous versions, a long series
67 would result in a single-line definition of VAR that could possibly
68 exceed the maximum line length of some make implementations.
70 Non-augmented variables are still output as they are defined in
75 - Support Fortran 90/95 with the new "fc" and "ppfc" languages.
76 Works the same as the old Fortran 77 implementation; just replace
77 F77 with FC everywhere (exception: FFLAGS becomes FCFLAGS).
78 Requires a version of autoconf which provides AC_PROG_FC (>=2.59).
80 - Support for conditional _LISP.
82 - Diagnose AC_CONFIG_AUX_DIR calls following AM_INIT_AUTOMAKE. (PR/49)
84 - Automake stops writing Makefile.ins as soons as it encounters an
85 error. (Warnings will not prevent output, but remember they can
86 be turned into errors with -Werror.)
88 - The restriction that SUBDIRS must contain direct children is gone.
95 - Define DIST_SUBDIRS even when the `no-dist' or `cygnus' options are used
96 so that `make distclean' and `make maintainer-clean' can work.
98 - Define AR and ARFLAGS even when only EXTRA_LIBRARIES are defined.
100 - Fix many rules to please FreeBSD make, which runs commands with `sh -e'.
102 - Polish diagnostic when no input file is found.
106 * Long standing bugs:
108 - Fix AM_PATH_PYTHON to correctly display $PYTHON when it has been
109 overridden by the user.
111 - Honor PATH_SEPARATOR in various places of the Automake package, for
114 - Adjust dependency tracking mode detection to ICC 8.0's new output.
117 - Fix install-sh so it can install the `mv' binary... using `mv'.
119 - Fix tru64 dependency tracking for libtool objects.
121 - Work around Exuberant Ctags when creating a TAGS files in a directory
122 without files to scan but with subdirectories to include.
124 * Bugs introduced by 1.8:
126 - Fix an "internal error" when @LIBOBJS@ is used in a variable that is
127 not defined in the same conditions as the _LDADD that uses it.
129 - Do not warn when JAVAROOT is overridden, this is legitimate.
133 * Long standing bugs:
135 - Quote filenames in installation rules, in case $DESTDIR, $prefix,
136 or any of the other *dir variables contain a space.
138 Please note that Automake does not and cannot support spaces in
139 filenames that are involved during the build. This change affects
140 only installation paths, so that `make install' does not bomb out
141 in packages configured with
142 ./configure --prefix '/c/Program Files'
144 - Fix the depfiles output so it works with GNU sed (<4.1) even when
145 POSIXLY_CORRECT is set.
147 - Do not AC_SUBST(LIBOBJS) in AM_WITH_REGEX. This macro was unusable
148 since Autoconf 2.54, which defines LIBOBJS itself.
150 - Fix a potential (but unlikely) race condition in parallel elisp
151 builds. (Introduced in 1.7.3.)
153 - Do not assume that users override _DEPENDENCIES in all conditions
154 where Automake will try to define them.
156 - Do not use `mkdir -p' in mkinstalldirs, unless this is GNU mkdir.
157 Solaris 8's `mkdir -p' is not thread-safe and can break parallel
160 This fix also affects the $(mkdir_p) variable defined since
161 Automake 1.8. It will be set to `mkdir -p' only if mkdir is GNU
162 mkdir, and to `mkinstalldirs' or `install-sh -d' otherwise.
164 - Secure temporary directory creation in `make distcheck'. (PR/413)
166 - Do not generate two build rules for `parser.h' when the
167 parser appears in two different conditionals.
169 - Work around a Solaris 8 /bin/sh bug in the test for dependency
170 checking. Usually ./configure will not pick this shell; so this
171 fix only helps cases where the shell is forced to /bin/sh.
173 * Bugs introduced by 1.8:
175 - In some situations (hand-written `m4_include's), aclocal would
176 call the `File::Spec->rel2abs' method, which was only introduced
177 in Perl 5.6. This new version reestablish support Perl 5.005.
179 It is likely that the next major Automake releases will require at
180 least Perl 5.6. Consider upgrading your development environment
181 if you are still using the five-year-old Perl 5.005.
183 - Automake would sometimes fail to define rules for targets listed
184 in variables defined in multiple conditions. For instance on
190 it would define only the `a.$(OBJEXT): a.c' rule and omit the
191 `b.$(OBJEXT): b.c' rule.
193 * New sections in manual:
195 - Third-Party Makefiles: how to interface third party Makefiles.
196 - Upgrading: upgrading packages to newer Automake versions.
197 - Multiple Outputs: handling tools that produce many outputs.
201 * A (well known) portability bug slipped in the changes made to
202 install-sh in Automake 1.8.1. The broken install-sh would refuse to
203 install anything on Tru64.
205 * Fix install rules for conditionally built python files. (This never
210 * Bugs introduced by 1.8:
212 - Fix Config.pm import error with old Perl versions (at least
213 5.005_03). One symptom is that aclocal could not find its macro
216 - Automake 1.8 used `mkdir -m 0755 -p --' to ensure that directories
217 created by `make install' are always world readable, even if the
218 installer happens to have an overly restrictive umask (e.g. 077).
219 This was a mistake and has been reverted. There are at least two
220 reasons why we must not use `-m 0755':
221 - it causes special bits like SGID to be ignored,
222 - it may be too restrictive (some setups expect 775 directories).
224 - Fix aclocal to honor definitions located in files which have been
225 m4_included manually. aclocal 1.8 had been updated to check
226 m4_included files for new requirements, but forgot that these
227 m4_included files can also provide new definitions.
229 Note that if you have such a setup, we recommend you get rid of
230 it. In the past, there was a reason to m4_include files manually:
231 aclocal used to duplicate entire M4 files into aclocal.m4, even
232 files that were distributed. Some packages were therefore
233 m4_including the distributed file directly, and playing some
234 tricks to ensure aclocal would not copy that file to aclocal.m4,
235 in order to limit the amount of duplication. Since aclocal 1.8.x
236 will precisely output m4_includes for local M4 files, we recommend
237 that you clean up your setup, removing all manual m4_includes and
238 letting aclocal output them.
240 - Output detailed menus in the Info version if the Automake manual,
241 so that Emacs can locate the indexes.
243 - configure.ac and configure were listed twice in DIST_COMMON (an
244 internal variable where Automake lists configury files to
245 distribute). This was harmless, but unaesthetic.
247 - Use `chmod a-w' instead of `chmod -w' as the latter honors umask.
248 This was an issue only in the Automake package itself, not in
251 - Automake assumed that all AC_CONFIG_LINKS arguments had the form
252 DEST:SRC. This was wrong, as some packages do
253 AC_CONFIG_LINKS($computedlinks). This version no longer abort in
256 - Contrary to mkinstalldirs, $(mkdir_p) was expecting exactly one
257 argument. This caused two kinds of failures:
258 - Rules installing data in a conditionally defined directory
259 failed when that directory was undefined. In this case no
260 argument was supplied.
261 - `make installdirs' failed, because several directories were
262 passed to $(mkdir_p). This was an issue only on platform
263 were $(mkdir_p) is implemented with `install-sh -d'.
264 $(mkdir_p) as been changed to accept 0 or more arguments, as
267 * Long-standing bugs:
269 - Fix an unexpected diagnostic occurring when users attempt
270 to override some internal variables that Automake appends to.
272 - aclocal now scans configure.ac for macro definitions (PR/319).
274 - Fix a portability issue with OSF1/Tru64 Make. If a directory
275 distributes files which are outside itself (this usually occurs
276 when using AC_CONFIG_AUX_DIR([../dir]) to use auxiliary files
277 from a parent package), then `make distcheck' fails due to an
278 optimization performed by OSF1/Tru64 Make in its VPATH handling.
279 (tests/subpkg2.test failure)
281 - Fix another portability issue with Sun and OSF1/Tru64 Make.
282 In a VPATH-build configuration, `make install' would install
283 nobase_ files to wrong locations.
285 - Fix a Perl `uninitialized value' diagnostic occurring when
286 automake complains that a Texinfo file does not have a
287 @setfilename statement.
289 - Erase config.status.lineno during `make distclean'. This file
290 can be created by config.status. Automake already knew about
291 configure.lineno, but forgot config.status.lineno.
293 - Distribute all files, even those which are built and installed
294 conditionally. This change affects files listed in conditionally
295 defined *_HEADERS and *_PYTHON variable (unless they are nodist_*)
296 as well as those listed in conditionally defined dist_*_DATA,
297 dist_*_JAVA, dist_*_LISP, and dist_*_SCRIPTS variables.
299 - Fix AM_PATH_LISPDIR to avoid \? in sed regular expressions; it
300 doesn't conform to POSIX.
302 - Normalize help strings for configure variables and options added
307 - Check for python2.4 in AM_PATH_PYTHON.
309 * Spurious failures in test suite:
311 - tests/libtool5.test, tests/ltcond.test, tests/ltcond2.test,
312 tests/ltconv.test: fix failures with CVS Libtool.
313 - tests/aclocal6.test: fix failure if autom4te.cache is disabled.
314 - tests/txinfo24.test, tests/txinfo25.test, tests/txinfo28.test:
315 fix failures with old Texinfo versions.
321 - The NEWS file is more verbose.
325 - Autoconf 2.58 or greater is required.
329 - Default source file names in the absence of a _SOURCES declaration
330 are made by removing any target extension before appending `.c', so
331 to make the libtool module `foo.la' from `foo.c', you only need to
334 lib_LTLIBRARIES = foo.la
335 foo_la_LDFLAGS = -module
337 For backward compatibility, foo_la.c will be used instead of
338 foo.c if this file exists or is the explicit target of a rule.
339 However -Wobsolete will warn about this deprecated naming.
341 - AR's `cru' flags are now set in a global ARFLAGS variable instead
342 of being hard-coded in each $(AR) invocation, so they can be
343 substituted from configure.ac. This has been requested by people
344 dealing with non-POSIX ar implementations.
346 - New warning option: -Woverride. This will warn about any user
347 target or variable definitions which override Automake
350 - Texinfo rules back up and restore info files when makeinfo fails.
352 - Texinfo rules now support the `html' target.
353 Running this requires Texinfo 4.0 or greater.
355 `html' is a new recursive target, so if your package mixes
356 hand-crafted `Makefile.in's with Automake-generated
357 `Makefile.in's, you should adjust the former to support (or
358 ignore) this target so that `make html' recurses successfully. If
359 you had a custom `html' rule in your `Makefile.am', it's better to
360 rename it as `html-local', otherwise your rule will override
361 Automake's new rule (you can check that by running `automake
362 -Woverride') and that will stop the recursion to subdirectories.
364 Last but not least, this `html' rule is declared PHONY, even when
365 overridden. Fortunately, it appears that few packages use a
366 non-PHONY `html' rule.
368 - Any file which is m4_included from configure.ac will appear as a
369 configure and Makefile.in dependency, and will be automatically
372 - The rules for rebuilding Makefiles and Makefile.ins will now
373 rebuild all Makefiles and all Makefile.ins at once when one of
374 configure's dependencies has changed. This is considerably faster
375 than previous implementations, where config.status and automake
376 were run separately in each directory (this still happens when you
377 change a Makefile.am locally, without touching configure.ac or
378 friends). Doing this also solves a longstanding issue: these
379 rebuild rules failed to work when adding new directories to the
380 tree, forcing you to run automake manually.
382 - For similar reasons, the rules to rebuild configure,
383 config.status, and aclocal.m4 are now defined in all directories.
384 Note that if you were using the CONFIG_STATUS_DEPENDENCIES and
385 CONFIGURE_DEPENDENCIES (formerly undocumented) variables, you
386 should better define them in all directories. This is easily done
387 using an AC_SUBST (make sure you prefix these dependencies with
388 $(top_srcdir) since this variable will appear at different
389 levels of the build tree).
391 - aclocal will now use `m4_include' instead of copying local m4
392 files into aclocal.m4. (Local m4 files are those you ship with
393 your project, other files will be copied as usual.)
395 Because m4_included files are automatically distributed, it means
396 for most projects there is no point in EXTRA_DISTing the list of
397 m4 files which are used. (You can probably get rid of
398 m4/Makefile.am if you had one.)
400 - aclocal will avoid touching aclocal.m4 when possible, so that
401 Autom4te's cache isn't needlessly invalidated. This behavior can
402 be switched off with the new `--force' option.
404 - aclocal now uses Autoconf's --trace to detect macros which are
405 actually used and will no longer include unused macros simply
406 because they where mentioned. This was often the case for macros
407 called conditionally.
409 - New options no-dist and no-dist-gzip.
411 - compile, depcomp, elisp-comp, install-sh, mdate-sh, mkinstalldirs,
412 py-compile, and ylwrap, now all understand --version and --help.
414 - Automake will now recognize AC_CONFIG_LINKS so far as removing created
415 links as part of the distclean target and including source files in
418 - AM_PATH_PYTHON now supports ACTION-IF-FOUND and ACTION-IF-NOT-FOUND
419 argument. The latter can be used to override the default behavior
422 - Automake will exit with $? = 63 on version mismatch. (So does
423 Autoconf 2.58) missing knows this, and in this case it will
424 emulate the tools as if they were absent. Because older versions
425 of Automake and Autoconf did not use this exit code, this change
426 will only be useful in projects generated with future versions of
429 - When using AC_CONFIG_FILES with multiple input files, Automake
430 generates the first ".in" input file for which a ".am" exists.
431 (Former versions would try to use only the first input file.)
433 - lisp_DATA is now allowed. If you are using the empty ELCFILES
434 idiom to disable byte-compilation of lisp_LISP files, it is
435 recommended that you switch to using lisp_DATA. Note that
436 this is not strictly equivalent: lisp_DATA will install elisp
437 files even if emacs is not installed, while *_LISP do not
438 install anything unless emacs is found.
440 - Makefiles will prefer `mkdir -p' over mkinstalldirs if it is
441 available. This selection is achieved through the Makefile
442 variable $(mkdir_p) that is set by AM_INIT_AUTOMAKE to either
443 `mkdir -m 0755 -p --', `$(mkinstalldirs) -m 0755', or
444 `$(install_sh) -m 0755 -d'.
448 - Because `mkdir -p' is available on most platforms, and we can use
449 `install-sh -d' when it is not, the use of the mkinstalldirs
450 script is being phased out. `automake --add-missing' no longer
451 installs it, and if you remove mkinstalldirs from your package,
452 automake will define $(mkinstalldirs) as an alias for $(mkdir_p).
454 Gettext 0.12.1 still requires mkinstalldirs. Fortunately
455 gettextize and autopoint will install it when needed. Automake
456 will continue to define the $(mkinstalldirs) and to distribute
457 mkinstalldirs when this script is in the source tree.
459 - AM_PROG_CC_STDC is now empty. The content of this macro was
460 merged in AC_PROG_CC. If your code uses $am_cv_prog_cc_stdc, you
461 should adjust it to use $ac_cv_prog_cc_stdc instead. (This
462 renaming should be safe, even if you have to support several,
463 versions of Automake, because AC_PROG_CC defines this variable
464 since Autoconf 2.54.)
466 - Some users where using the undocumented ACLOCAL_M4_SOURCES
467 variable to override the aclocal.m4 dependencies computed
468 (inaccurately) by older versions of Automake. Because Automake
469 now tracks configure's m4 dependencies accurately (see m4_include
470 above), the use of ACLOCAL_M4_SOURCES should be considered
471 obsolete and will be flagged as such when running `automake
476 - Defining programs conditionally using Automake conditionals no
477 longer leads to a combinatorial explosion. The following
478 construct used to be troublesome when used with dozens of
493 Likewise for _SOURCES, _LDADD, and _LIBADD variables.
495 - Due to implementation constraints, previous versions of Automake
496 proscribed multiple conditional definitions of some variables
506 All _PROGRAMS, _LDADD, and _LIBADD variables were affected.
507 This restriction has been lifted, and these variables now
508 support multiple conditional definitions as do other variables.
510 - Cleanup the definitions of $(distdir) and $(top_distdir).
511 $(top_distdir) now points to the root of the distribution
512 directory created during `make dist', as it did in Automake 1.4,
513 not to the root of the build tree as it did in intervening
514 versions. Furthermore these two variables are now only defined in
515 the top level Makefile, and passed to sub-directories when running
518 - The --no-force option now correctly checks the Makefile.in's
519 dependencies before deciding not to update it.
521 - Do not assume that make files are called Makefile in cleaning rules.
523 - Update .info files in the source tree, not in the build tree. This
524 is what the GNU Coding Standard recommend. Only Automake 1.7.x
525 used to update these files in the build tree (previous versions did
526 it in the source tree too), and it caused several problems, varying
527 from mere annoyance to portability issues.
529 - COPYING, COPYING.LIB, and COPYING.LESSER are no longer overwritten
530 when --add-missing and --force-missing are used. For backward
531 compatibility --add-missing will continue to install COPYING (in
532 `gnu' strictness) when none of these three files exist, but this
533 use is deprecated: you should better choose a license yourself and
534 install it once for all in your source tree (and in your code
537 - Fix ylwrap so that it does not overwrite header files that haven't
538 changed, as the inline rule already does.
540 - User-defined rules override automake-defined rules for the same
541 targets, even when rules do not have commands. This is not new
542 (and was documented), however some of the automake-generated
543 rules have escaped this principle in former Automake versions.
544 Rules for the following targets are affected by this fix:
546 clean, clean-am, dist-all, distclean, distclean-am, dvi, dvi-am,
547 info, info-am, install-data-am, install-exec-am, install-info,
548 install-info-am, install-man, installcheck-am, maintainer-clean,
549 maintainer-clean-am, mostlyclean, mostlyclean-am, pdf, pdf-am,
550 ps, ps-am, uninstall-am, uninstall-info, uninstall-man
552 Practically it means that an attempt to supplement the dependencies
553 of some target, as in
557 will now *silently override* the automake definition of the
558 rule for this target. Running `automake -Woverride' will diagnose
559 all such overriding definitions.
561 It should be noted that almost all these targets support a *-local
562 variant that is meant to supplement the automake-defined rule
563 (See node `Extending' in the manual). The above rule should
566 clean-local: my-clean-rule
568 These *-local targets have been documented since at least
569 Automake 1.2, so you should not fear the change if you have
570 to support multiple automake versions.
574 - The Automake manual is now distributed under the terms of the GNU FDL.
576 - Targets dist-gzip, dist-bzip2, dist-tarZ, dist-zip are always defined.
578 - core dumps are no longer removed by the cleaning rules. There are
579 at least three reasons for this:
580 1. These files should not be created by any build step,
581 so their removal do not fit any of the cleaning rules.
582 Actually, they may be precious to the developer.
583 2. If such file is created during a build, then it's clearly a
584 bug Automake should not hide. Not removing the file will
585 cause `make distcheck' to complain about its presence.
586 3. Operating systems have different naming conventions for
587 core dump files. A core file on one system might be a
588 completely legitimate data file on another system.
590 - RUNTESTFLAGS, CTAGSFLAGS, ETAGSFLAGS, JAVACFLAGS are no longer
591 defined by Automake. This means that any definition in the
592 environment will be used, unless overridden in the Makefile.am or
593 on the command line. The old behavior, where these variables were
594 defined empty in each Makefile, can be obtained by AC_SUBSTing or
595 AC_ARG_VARing each variable from configure.ac.
597 - CONFIGURE_DEPENDENCIES and CONFIG_STATUS_DEPENDENCIES are now
598 documented. (The is not a new feature, these variables have
599 been there since at least Automake 1.4.)
602 * Fix install-strip to work with nobase_ binaries.
603 * Fix renaming of #line directives in ylwrap.
604 * Rebuild with Autoconf 2.59. (1.7.8 was not installable with pdksh.)
607 * Remove spurious blank lines in cleaning rules introduced in 1.7.7.
608 * Fix detection of Debian's install-info, broken since version 1.5.
609 (Debian bug #213524).
610 * Honor -module if it appears in AM_LDFLAGS (i.e., relax name checking)
611 This was only done for libfoo_LDFLAGS and LDFLAGS in previous versions.
614 * The implementation of automake's --no-force option is unreliable,
615 so this option is ignored in this version. A real fix will appear in
616 Automake 1.8. (Debian Bug #206299)
617 * AM_PATH_PYTHON: really check the whole list of interpreters if no
618 argument is given. (PR/399)
619 * Do not warn about leading `_' in variable names, even with -Wportability.
620 * Support user redefinitions of TEXINFO_TEX.
621 * depcomp: support AIX Compiler version 6.
622 * Fix missing rebuilds during `make dist' with BSD make.
623 (Could produce tarballs containing out-of-date files.)
624 * Resurrect multilib support.
625 * Noteworthy manual updates:
626 - Extending aclocal: how to write m4 macros that won't trigger warnings
628 - A Shared Library: Rewrite and split into subsections.
631 * Fix depcomp's icc mode for ICC 7.1.
632 * Diagnose calls to AC_CONFIG_FILES and friends with not enough arguments.
633 * Fix maintainer-clean's removal of autom4te.cache in VPATH builds.
634 * Fix AM_PATH_LISPDIR to work with POSIXLY_CORRECT=1.
635 * Fix the location reported in some diagnostics related to AUTOMAKE_OPTIONS.
636 * Remove Latin-1 characters from elisp-comp.
637 * Update the manual's @dircategory to match the Free Software Directory.
640 * Update install-sh's license to remove an advertising clause.
642 * Fix a bug introduced in 1.7.4, related to BUILT_SOURCE handling,
643 that caused invalid Makefile.ins to be generated.
644 * Make sure AM_MAKE_INCLUDE doesn't fail when a `doit' file exists.
645 * New FAQ entry: renamed objects.

661 * Minor documentation fixes.
664 * Fix stamp files numbering (when using multiple AC_CONFIG_HEADERS).
665 * Query distutils for `pythondir' and `pythonexecdir', instead of
666 using an hardcoded path. This should allow builds on 64-bit
667 distributions that usually use lib64/ instead of lib/.
668 * AM_PATH_PYTHON will also search for python2.3.
669 * elisp files are now built all at once instead of one by one. Besides
670 incurring a speed-up, this is required to support interdependent elisp files.
672 - `make distcheck' will now work in `_inst/' and `_build' instead
673 of `=inst/' and `=build/'
674 - use `_dirstamp' when the file-system doesn't support `.dirstamp'

677 * Fix some incompatibilities with upcoming perl-5.10.
678 * Properly quote AC_PACKAGE_TARNAME and AC_PACKAGE_VERSION when defining
681 - dashmstdout and dashXmstdout modes: don't use `-o /dev/null', this
682 is troublesome with gcc and Solaris compilers. (PR/385)
683 - makedepend mode: work with Libtool. (PR/385 too)
685 * better support for unusual gettext setups, such as multiple po/ directories
687 - Flag missing po/ and intl/ directories as warnings, not errors.

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

710 * Don't use single suffix inference rules when building `.info'-less
711 Info files, for the sake of Solaris make.
712 * The `check' target now depends on `$(BUILT_SOURCES)'. (PR/359)
713 * Recognize multiple inference rules such as `.a.b .c.d:'. (PR/371)
714 * Warn about multiple inference rules when -Wportability is used. (PR/372)
715 * Fix building of deansified files from subdirectories. (PR/370)
716 * Add missing `fi' in the .c->.obj rules.
717 * Improve install-sh to work even when names contain spaces or certain
718 (but not all) shell metachars.
719 * Fix the following spurious failures in the test suite:
720 depcomp2.test, gnits2.test, gnits3.test, python3.test, texinfo13.test
721 * Noteworthy manual updates:
722 - Augment the section about BUILT_SOURCES.
723 - Mention that AM_PROG_CC_STDC is a relic that is better avoided today.
726 * Honor `ansi2knr' for files built in subdirectories, or using per-targets
728 * Aclocal should now recognize macro names containing parentheses, e.g.
729 AC_DEFUN([AC_LANG_PREPROC(Fortran 90)], [...]).
730 * Erase *.sum and *.log files created by DejaGnu, during `make distclean'.
732 * Install Python files even if they were built. (PR/369)
733 * Have stamp-vti dependent upon configure instead of configure.ac, as the
734 version might not be defined in the latter. (PR/358)
735 * Reorder arguments passed to a couple of commands, so things works
736 when POSIXLY_CORRECT=1.
737 * Fix a regex that can cause Perl to segfault on large input.
739 * Fix distribution of packages that have some sources defined conditionally,
740 as in the `Conditional compilation using Automake conditionals' example
742 * Fix spurious test suite failures on IRIX.
743 * Don't report a required variable as undefined if it has been
744 defined conditionally for the "right" conditions.
745 * Fix cleaning of the /tmp subdirectory used by `make distcheck', in case
746 `make distcheck' fails.
747 * Fix distribution of included Makefile fragment, so we don't create
748 spurious directories in the distribution. (PR/366)
749 * Don't complain that a target lacks `.$(EXEEXT)' when it has it.
752 * Autoconf 2.54 is required.
753 * `aclocal' and `automake' will no longer warn about obsolete
754 configure macros. This is done by `autoconf -Wobsolete'.
755 * AM_CONFIG_HEADER, AM_SYS_POSIX_TERMIOS and
756 AM_HEADER_TIOCGWINSZ_NEEDS_SYS_IOCTL are obsolete (although still
757 supported). You should use AC_CONFIG_HEADERS, AC_SYS_POSIX_TERMIOS,
758 and AC_HEADER_TIOCGWINSZ instead. `autoupdate' can upgrade
759 `configure.ac' for you.
760 * Support for per-program and per-library `_CPPFLAGS'.
761 * New `ctags' target (builds CTAGS files).
762 * Support for -Wmumble and -Wno-mumble, where mumble is a warning category
763 (see `automake --help' or the manual for a list of them).
764 * Honor the WARNINGS environment variable.
765 * Omit the call to depcomp when using gcc3: call the compiler directly.

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

811 (e.g. AC_SUBST(mumble_LDFLAGS) when 'mumble' is not a target).
812 - Fix the definition of AUTOMAKE and ACLOCAL in configure.
815 * Autoconf 2.52 is required.
816 * automake no longer run libtoolize.
817 This is the job of autoreconf (from GNU Autoconf).
818 * `dist' generates all the archive flavors, as did `dist-all'.
819 * `dist-gzip' generates the Gzip tar file only.
820 * Combining Automake Makefile conditionals no longer lead to a combinatorial
821 explosion. Makefile.in's keep a reasonable size.

823 are no longer shipped, since Autoconf 2.52 provides them (both as AM_
825 * `#line' of Lex and Yacc files are properly set.
826 * EXTRA_DIST can contain generated directories.
827 * Support for dot-less extensions in suffix rules.
828 * The part of the distcheck target that checks whether distclean actually

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