# Don't include <ctype.h> because on OSF/1 3.0 it includes
|

# <sys/types.h> which includes <sys/select.h> which contains a
|
||||
# prototype for select. Similarly for bzero.
|

#
|
||||
# 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.
