   Does this mean the the 386 version (a 32bit version of Xenix) has 
limitations on huge array sizes?  I was under the impression that the
386 version of Xenix C compilier was a non-segmented 32bit compilier 
in all respects.  Other than the 32bit int's pointers etc. What are the
other features that are different than the 286 version of the Xenix 
compilier?
