Bison patch for glr.c enum warnings

[Paul Eggert]

I installed the following patch into Bison to fix one of the problems
reported by Nelson H.F. Beebe in
<http://mail.gnu.org/pipermail/bug-bison/2002-November/001872.html>.

2002-11-12  Paul Eggert  <address@hidden>

        * data/glr.c (yydoAction): Return YYRESULTTAG, not int.
        (yyglrReduce): Return yyok, not 0.
        This should avoid the enumerated-type warnings reported
        by Nelson H.F. Beebe in
        <http://mail.gnu.org/pipermail/bug-bison/2002-November/001872.html>.
