BSD-based systems (SunOS and 4.3BSD, for example) specifically state
on the chmod(2) man page that a non-superuser process writing to a
file automatically clears the SUID and SGID bits.  That makes sense.

But, in going through the SVID (Third Edition) and the SVR4 manuals,
I can't find any reference to this feature.  Do the AT&T Unices really
not do this ?
