+       tests: fix empty unions.
+       Empty unions are not accepted by the ISO C99 grammar or by at
+       least some versions of Sun Studio.  Reported by Wolfgang S. Kechel
+       at
+       <http://lists.gnu.org/archive/html/bug-bison/2011-08/msg00003.html>.
+       * NEWS (2.5.1): Document fix.
+       * THANKS (Wolfgang S. Kechel): Add.
+       * tests/existing.at (GNU Cim Grammar)
+       (GNU pic (Groff 1.18.1) Grammar.): Remove empty %union.

+
+       global: remove unnecessary horizontal tabs.
+       This change was made by applying emacs' untabify function to
+       nearly all files in Bison's repository.  Required tabs in make
+       files, ChangeLog, regexps, and test code were manually skipped.
+       Other notable exceptions and changes are listed below.
+       * bootstrap: Skip because we sync this with gnulib.
+       * data/m4sugar/foreach.m4
+       * data/m4sugar/m4sugar.m4: Skip because we sync these with
+       Autoconf.
+       * djgpp: Skip because I don't know how to test djgpp properly, and
+       this code appears to be unmaintained anyway.
+       * README-hacking (Hacking): Specify that tabs should be avoided
+       where not required.

+
+       build: avoid YACC typo inherited from Autoconf.
+       The typo shows up in the `configure --help' output.  Reported by
+       W.C.A. Wijngaards and Paul Eggert at
+       <http://lists.gnu.org/archive/html/bug-bison/2011-07/msg00000.html>.
+       * README-hacking (Release Procedure): Remind about updating
+       maintainer tools before a release.
+       * THANKS (W.C.A. Wijngaards): Add.
+       * configure.ac (AC_PREREQ): Set to 2.68, which fixes the YACC
+       typo.

+
+       build: create xz instead of bzip2 tarballs.
+       Suggested by Jim Meyering at
+       <http://lists.gnu.org/archive/html/bug-bison/2011-06/msg00012.html>.
+       * README-hacking (Release Procedure): Update example.
+       * configure.ac (AM_INIT_AUTOMAKE): Replace dist-bzip2 with
+       dist-xz.

+       doc: clean up references to `Locations Overview'.
+       * doc/bison.texinfo (Locations Overview): Rename node to...
+       (Locations): ... this, which is its section name.  Update menus to
+       match that and not to use the title `Tracking Locations', which is
+       a different section.

+       doc: clean up references to `Tracking Locations'.
+       * doc/bison.texinfo (Locations): Rename node to...
+       (Tracking Locations): ... this, which is its section name, and
+       update all cross references.  The trouble is that there is another
+       node about locations.  Its section name is `Locations', which was
+       easily confused with the node name of this node.  Moreover, its
+       node name is `Locations Overview', which was mistakenly used to
+       label some cross references to this node.
