Yes, I do.  I do it to develop a product which ultimately runs on DOS on a
286.  I assume you have a good reason, too.  It's slow, about half as fast
as it would be if you ran 386 Xenix on the same machine.  The linker is
*very* slow.

I get the feeling that it's not supported any more by SCO.  The problems
I've noted: csh crashes using the `...` construct sometimes.  'Make' has
trouble with great big makefiles (I had to split one in two).  sdb has some
problems (but it does on 386 Xenix, too).

But it all works well enough to be useful.  It's something I endure.
