And have you tried with the fix I made to that change a couple days ago:
2003-07-04 Jeff Law <law@redhat.com>
* expr.c (do_store_flag): Pass in the correct result type
when calling fold_single_bit_test.
* fold-const.c (fold_single_bit_test): Use result_type for the
result when folding a sign bit test.
