+ * README: Rationalize and reorganize the (brief) description of

+ mailing lists, point him to the relevant webpages, where he can
+ also subscribe via a web form.

+ readme: update advice about testsuite execution
+ * README: Now that the automake testsuite uses the parallel-tests
+ driver, there is no need for the user to capture the stdout of
+ "make check" to determine which tests have failed: a detailed log
+ is automatically saved into the `tests/test-suite.log' file.
+ Since we are at it, improve the wording by dropping an extra
+ "please".

+ hacking: some more fixlets
+ * HACKING (Release Procedure): Place the list of pre-release
+ bootstrap-and-test commands on a line of its own, so it's easy to
+ select and then paste it into a terminal window.
+ Fix the explanation of "make git-release", as, since the previous
+ change, "make git-release" would simply run "make dist" rather
+ than "make distcheck".
+ Suggestion from Jim Meyering.

+ * HACKING (Release procedure): ... state here that "make check"
+ and "make distcheck" should be run before calling "make git-dist".

+
+ dist-xz, dist-bzip2: don't hard-code -9, honor envvar settings
+ Before the present change, automake-generated `dist-xz' rule used
+ a hard-coded `xz -9'. That was a problem because on this front,
+ xz differs from gzip and bzip2. While the latter two don't incur
+ any run-time decompression penalty for using a higher compression
+ level, specifying -9 with xz imposes a potentially fatal virtual
+ memory requirement on any client that wants to decompress your
+ tar.xz file.
+ People have complained that a tarball compressed with -9 cannot
+ be uncompressed in a low-memory environment (wrt-based embedded).
+ Hence, instead of defaulting to -9, which is useful only for very
+ large tarballs, it defaults to -e (equivalent to -6e). This
+ limits the default memory requirements imposed on decompressors,
+ yet still gives very good compression ratios.
+ * lib/am/distdir.am (dist-xz): Do not hard-code xz's -9: that made
+ it impossible to override. Actually don't default to -9, either,
+ since that induced inordinately large virtual memory usage when
+ merely decompressing. Instead, use its XZ_OPT envvar, defaulting
+ to -e if not defined. Suggested by Lasse Collin.
+ (dist, dist-all) [?XZ?]: Likewise
+ (dist-bzip2): Similarly, do not hard-code -9, but do continue to
+ use -9 by default. Honor the BZIP2 envvar.
+ (dist, dist-all) [?BZIP2?]: Likewise
+ * NEWS: Update.
+ * doc/automake.texi (The Types of Distributions): Describe the
+ newly enabled environment variables.

+ tests: fix spurious failures due to missing 'yywrap()' function
+
+ The AC_PROG_LEX Autoconf macro does not diagnose a failure to find
+ the "lex library" expected to provide a `yywrap' function (function
+ which is required to link most lex-generated programs). On the
+ contrary, when all the link attempts (i.e., with `-ll' and `-lfl')
+ fail, configure declares that no lex library is needed, and simply
+ proceeds with the configuration process -- only for the build to
+ possibly fail later, at make time.
+
+ This behaviour is intended; the Autoconf manual reads:
+ ``You are encouraged to use Flex in your sources, since it is
+ both more pleasant to use than plain Lex and the C source it
+ produces is portable. In order to ensure portability, however,
+ you must either provide a function `yywrap' or, if you don't use
+ it (e.g., your scanner has no `#include'-like feature), simply
+ include a `%noyywrap' statement in the scanner's source.''
+
+ This AC_PROG_LEX behaviour is causing some spurious failures of
+ the Automake testsuite in environments which lack a proper library
+ providing `yywrap' (this happens for example on Fedora-based
+ systems). The proper workaround is to simply provide a fall-back
+ implementation of `yywrap' in our lexers.
+
+ See also partially-overlapping commit `v1.11-871-geb147a1' (from
+ the 'testsuite-work' branch), which was motivated by similar
+ spurious failures experienced when cross-compiling.

+ Solaris dmake, that redirect the output of recipes to temporary
+ files or pipes when run in parallel mode. Since we are at it,
+ simplify the detection of a working `expect' program, and throw
+ in other minor simplifications.

+ Yikes. Cater to this incompatibility, by relaxing the test when
+ a faulty `rm' is detected.
