The warning goes away after applying
expr.c: 1.561, 1.562
fold-const.c: 1.273, 1.276
tree.h: 1.419
to the gcc-3.3 branch (patches applied cleanly, with offset).
Relevant changelog entries:

PR c/11428
* 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.
2003-07-02 Jeff Law <law@redhat.com>
* expr.c (do_store_flag): Remove special case folding for
single bit tests. Instead call back into the commonized folder
routine.
* fold-const.c (fold_single_bit_test): New function, mostly
extracted from do_store_flag, with an additional case extracted
from fold.
(fold): Call fold_single_bit_test appropriately.
* tree.h (fold_single_bit_test): Prototype.
Thanks!
