    Update to 2.4.1:

    * Changes in version 2.4.1 (2008-12-11):

    ** In the GLR defines file, unexpanded M4 macros in the yylval and yylloc
       declarations have been fixed.

    ** Temporary hack for adding a semicolon to the user action.

      Bison used to prepend a trailing semicolon at the end of the user
      action for reductions.  This allowed actions such as

        exp: exp "+" exp { $$ = $1 + $3 };

      instead of

        exp: exp "+" exp { $$ = $1 + $3; };

      Some grammars still depend on this `feature'.  Bison 2.4.1 restores
      the previous behavior in the case of C output (specifically, when
      neither %language or %skeleton or equivalent command-line options
      are used) to leave more time for grammars depending on the old
      behavior to be adjusted.  Future releases of Bison will disable this
      feature.

    ** A few minor improvements to the Bison manual.
