-# A similar problem afflicts HP/UX, but it also hits <sys/time.h>
-#
-# 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.
