+       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.
