* configure.in: Check for the stat call, since profile_update_file

	needs to know whether it exists.  (It doesn't on the Mac.)

* prof_file.c (profile_update_file): Change use of HAS_STAT to
	HAVE_STAT, to confirm with autoconf test.  If the stat() call does not
	exist, assume that our in-core memory image is correct, and never
	re-read the profile file unless we explicitly close it.
