I'm not positive about this, but I think the SCCS question is really one of licensing (again!). SCCS was licensed with PWB/UNIX, but not with V7 or 32V. It should be covered by a System III license. Since a System III license is not required to obtain 4.2BSD, SCCS can't be included. Roger Bielefeld decvax!cwruecmp!cdcvax!rab
