Once upon a time, what was UNIX(TM)/(R) was a particular set of code, or
authorized derivative code.  That was quite a while ago.  One of the
(relatively) good things that came out of the "UNIX Wars" was that UNIX
(R) is not dependent upon a particular source code set or derivation
thereof, but rather conformance to specifications and, for
the right to carry the UNIX(R) registered trademark, passage of
certification tests (submission to the tests for certification and
branding is not free, though the standards upon which the tests are
based are available for free (as in beer, not freedom)).
