should take precedence over the same-named automake-provided macro
(defined in '/usr/local/share/aclocal-1.14/vala.m4').
-* Obsolescent features:
-
- - Use of suffix-less info files (that can be specified through the
- '@setfilename' macro in Texinfo input files) is discouraged, and
- its use will raise warnings in the 'obsolete' category.
+* C compilation, and the AC_PROG_CC and AM_PROG_CC_C_O macros:
+
+ - The 'compile' script is now unconditionally required for all
+ packages that perform C compilation (note that if you are using
+ the '--add-missing' option, automake will fetch that script for
+ you, so you shouldn't need any explicit adjustment).
+ This new behaviour is needed to avoid obscure errors when the
+ 'subdir-objects' option is used, and the compiler is an inferior
+ one that doesn't grasp the combined use of both the "-c -o"
+ options; see discussion about automake bug#13378 for more details:
+ <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#35>
+ <http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13378#44>
+
+ - Automake will automatically enhance the AC_PROG_CC autoconf macro
+ to make it check, at configure time, that the C compiler supports
+ the combined use of both the "-c -o" options. This "rewrite" of
+ AC_PROG_CC is only meant to be temporary, since future Autoconf
+ versions should provide all the features Automake needs.
+
+ - The AM_PROG_CC_C_O is no longer useful, and its use is a no-op
+ now. Future Automake versions might start warning that this
+ macro is obsolete. For better backward-compatibility, this macro
+ still sets a proper 'ac_cv_prog_cc_*_c_o' cache variable, and
+ define the 'NO_MINUS_C_MINUS_O' C preprocessor symbol, but you
+ should really stop relying on that.
+
- * Obsolescent features:
-
- - Use of suffix-less info files (that can be specified through the
- '@setfilename' macro in Texinfo input files) is discouraged, and
- its use will raise warnings in the 'obsolete' category. Simply
- use the '.info' extension for all your info files, transforming
- usages like:
-
- @setfilename myprogram
-
- into:
-
- @setfilename myprogram.info
-
- - Use of Texinfo input files with '.txi' or '.texinfo' extensions
- is discouraged, and its use will raise warnings in the 'obsolete'
- category. You are advised to simply use the '.texi' extension
- instead.
-
- * Documentation fixes:
-
- - The long-deprecated but still supported two-arguments invocation form
- of AM_INIT_AUTOMAKE is documented once again. This seems the sanest
- thing to do, given that support for such an usage might need to remain
- in place for a unspecified amount of time in order to cater for people
- who want to define the version number for their package dynamically at
- configure runtime (unfortunately, Autoconf does not yet support this
- scenario, so we cannot delegate the work to it).
-
+* Texinfo support:
+
+ - Automake can now be instructed to place '.info' files generated from
+ Texinfo input in the builddir rather than in the srcdir; this is done
+ specifying the new automake option 'info-in-builddir'. This feature
+ was requested by the developers of GCC, GDB, GNU binutils and the GNU
+ bfd library. See the extensive discussion about automake bug#11034
+ for more details.
+
+ - For quite a long time, Automake has been implementing an undocumented
+ hack which ensured that '.info' files which appeared to be cleaned
+ (by e.g. being listed in the CLEANFILES or DISTCLEANFILES variables)
+ were built in the builddir rather than in the srcdir; this hack was
+ introduced to ensure better backward-compatibility with packages such
+ as Texinfo, which did things like:
+
+ info_TEXINFOS = texinfo.txi info-stnd.texi info.texi
+ DISTCLEANFILES = texinfo texinfo-* info*.info*
+ # Do not create info files for distribution.
+ dist-info:
+ @:
+
+ in order not to distribute generated '.info' files.
+
+ Now that we have the 'info-in-builddir' option that explicitly causes
+ generated '.info' files to be placed in the builddir, this hack should
+ be longer necessary, so we deprecate it with runtime warnings. It will
+ likely be removed altogether in Automake 1.14.
