Xenix/386 currently has this. The current version actually only supports
the small model, but the 386 small model is 2GB segments, close to a
linear addressing space. Virtual memory is standard. Bell Technologies
also sells the AT&T certified port (for which they wrote many device
drivers) for $400 including C compiler. I haven't gotten mine yet, so I
have no idea how good it is. I would use Xenix if you can, the compiler
is *much* better than PCC.
