size_t -> YYSIZE_T typo in yacc.c

[Paul Eggert]

While looking into address@hidden's bug report I noticed an obvious
typo in yacc.c.  I installed this fix:

2006-05-14  Paul Eggert  <address@hidden>

        * data/yacc.c (yytnamerr): Fix typo: local var should be of type
        YYSIZE_T, not size_t.
        * tests/regression.at (Trivial grammars): New test, to catch
        the error fixed by the above patch.
