Yes, also several UTX-32 utilities are either AT&T UNIX System V
versions or incorporate features from ditto.  (E.g., /bin/ed.)

The apparent goal of the Compion port of UNIX done for Gould was
to provide a merged 4.2BSD/System V system.  My feeling is that
neither the 4.2BSD nor the System V camp is satisfied this way;
indeed, I still felt it necessary to bring up the BRL System V
emulation environment on UTX-32.

There is of course work underway to merge these two major UNIX
variants, especially at Sun Microsystems (under AT&T contract),
so at some future date 4.nBSD may provide System V compatibility
in one form or another.  However, 4.2BSD isn't, and certainly
problems can arise from any change in its semantics (including
C library routines).

(In other words, I agree with Ron that UTX-32 is not 4.2BSD.)
