+ 
+       Enable `set -e' in more tests (plus some tweakings).
+       * tests/mkinstall.test: Enable `errexit' shell flag, and related
+       changes.  Add a trailing `:' command, if needed.
+       * tests/mdate2.test: Likewise.
+       * tests/objc.test: Likewise.
+       * tests/noinst.test: Likewise.
+       * tests/outdir.test: Likewise.
+       * tests/number.test: Likewise.

+       * tests/req.test: Likewise.
+       * tests/rulepat.test: Likewise.
+       * tests/specflg6.test: Likewise.
+       * tests/spell3.test: Likewise.
+       * tests/parse.test: Likewise, and ...
+       (configure.in): Use the stub created by ./defs, rather than
+       writing it from scratch.  Remove useless calls to AC_PROG_RANLIB
+       and AC_OUTPUT.
+       * tests/mdate4.test: Likewise.
+       * tests/mkinstall.test: Likewise, and ...
+       (configure.in): ... drop useless call to `AC_OUTPUT'.
+       * tests/output.test: Enable `errexit' shell flag, and related
+       changes.  Add a trailing `:' command.
+       (configure.in): Modernize.
+       * tests/output2.test: Likewise.
+       * tests/output3.test: Likewise.
+       * tests/output4.test: Likewise.
+       * tests/mdate3.test: Enable `errexit' shell flag, and related
+       changes.  Prefer `$me' over hard-coded test name.  Do not move
+       non-existent or useless files in the build auxiliary directory.
+       * tests/nodistdir.test: Enable `errexit' shell flag, and related
+       changes.  Prefer trailing `:' over trailing `Exit 0'.
+       * tests/nodist.test: Likewise.  Also, prefer cat + here-doc over
+       echo to create input test files, and do not create useless dummy
+       C source files.
+       * tests/nodist2.test: Likewise.
+       * tests/ppf77.test: Enable `errexit' shell flag, with related
+       changes.  Add a trailing `:' command.  Do not create useless
+       dummy source files.
+       * tests/spelling.test: Enable `errexit' shell flag, with related
+       changes.  Add a trailing `:' command.  Also, grep Automake error
+       message.
+       * tests/specflg3.test: Enable `errexit' shell flag, with related
+       changes.  Avoid unportable use of `-e' option of fgrep.  Prefer
+       trailing `:' over trailing `Exit 0'.  Remove extra empty lines,
+       and cosmetic changes to whitespaces.
+       * tests/obsolete.test: Enable `errexit' shell flag, with related
+       changes.  Improve verbosity.  Other miscellanous changes.
+ 
 +2010-11-30  Stefano Lattarini  <stefano.lattarini@gmail.com>
 +
 +      Improve and extend tests on `:=' variable assignments.
 +      * tests/colneq.test: Avoid redundant use of variable assignments
 +      in Makefile.am.  Use command-line automake options instead of
 +      editing AUTOMAKE_OPTIONS in Makefile.am.  Make grepping of the
 +      generated Makefile.in slightly stricter.  Add a trailing `:'
 +      command.
 +      * tests/colneq2.test: Do not create unneeded dummy files.  Run
 +      also autoconf, ./configure and make.  Add trailing `:' command.
 +      * tests/colneq3.test: New test, similar to colneq.test, but
 +      running also autoconf, ./configure and make.
 +      * tests/Makefile.am (TESTS): Update.
 +
 +2010-11-26  Stefano Lattarini  <stefano.lattarini@gmail.com>
 +
 +      Remove long-deprecated options --Werror and --Wno-error.
 +      These options has been deprecated at least since commit
 +      "Release-1-6-1b-35-gc037f20", dated 2002-07-06.
 +      * automake.in (parse_arguments): Do not recognize anymore options
 +      `--Werror' and `--Wno-error' as synonyms of respectively `-Werror'
 +      and `-Wno-error'.
 +      * tests/werror.test: Update: use `-Werror' instead of `--Werror'.
 +      * NEWS: Update.
 +
