I almost forgot I added a check in expr.c  to assert when pointer's
modes is different from the size_type's mode.  This can only happen
for targets like ia64-hpux and s390x.  I don't support those yet but
it should be easy to support that case, I think.

Thanks,

        * expr.c (expand_expr_real_1): Add FIXME/assert for the unhandle case
        where the modes of the two operands are different.
