# This test used to merely assign f=$1 in main(), but that was
# optimized away by HP unbundled cc A.05.36 for ia64 under +O3,
# presumably on the basis that there's no need to do that store if the
# program is about to exit. Conversely, the AIX linker optimizes an
# unused external declaration that initializes f=$1. So this test
# program has both an external initialization of f, and a use of f in
# main that affects the exit status.
