Fix three nits found by Coverity, adding null checks and comments. [This commit only makes two changes. One change in the original patch is just adding a comment, and another adds a 'base != NULL' check to silence Coverity, but a comment adds that that base is never going to be NULL. I didn't backport that change. --amk]

# it's reported that this is fixed in the autoconf cvs already.
# AC_LANG_FUNC_LINK_TRY(C)(FUNCTION)
# ----------------------------------
# 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.
