XENIX 286 runs also on AT/286-machine. But it uses the Large Memory-Model,
(Compiler option -MLe) so programs can be larger than 64 kb. There are some
restrictions in comparison to what a 386-UNIX is able to. But when gcc works
with XENIX/286 you can't assume to get it working with Coherent. Also XENIX 
is SysV R.2 (unless you have a copy of the old stuff).
