stmt.c (expand_case): Use build_int_cst.
2005-06-01 Richard Guenther <rguenth@gcc.gnu.org>
* stmt.c (expand_case): Use build_int_cst.
(node_has_low_bound): Likewise, and correct type mismatch.
(node_has_high_bound): Likewise.
* fold-const.c (fold_binary): Ensure we build trees
with the correct types - undo what STRIP_NOPS possibly did.
