Compilation problem with Yacc

[Xun Sun]

Hi,

Today when I tried to compile grub2 from latest cvs on my Fedora Core
2 system, it errored out with the messages:

The problem as far as I can tell is that the @YACC@ env identified by
./configure was not ued, and the default YACC program (which is from
byacc-1.9-27) parsed the normal/parser.y wrongly.

The patch bellow resolves the problem for me:

Makes sense?
