'fraid it isn't. Unix is a trademark and can only be applied to systems
which the trademark owner approves. Just 'cos the code has a certain
heritage doesn't mean that the current version is approved. There is
a FAQ somewhere which discusses all the issues - I forget the details.

True - I was over zealous there. However the release was given approval for
the Unix label to be applied.

It was Linux-FT - I believe the company producing it is now defunct :-(
