printing problem in yacc.c, glr.c (more than INT_MAX rules)

[Paul Eggert]

I installed the following patch, to correct one bug for grammars that
have more than INT_MAX rules.  I'm sure there are other such bugs, but
this one is easy to fix.

        * data/glr.c (yy_reduce_print): Don't assume that yyrline[yyrule]
        promotes to int; it might be unsigned int.
        * data/yacc.c (yy_reduce_print): Likewise.
