As Bruce mentioned, this is due to the conflict among changes we made.
Included patches should fix the problem(I changed all MB to
MULTIBYTE). Please let me know if you have further problem.

P.S. I did not include pathces to configure and gram.c to save the
file size(configure.in and gram.y modified).
