Since the Microport V/386 code is based on (and is identical at the
system call level) to the 386/ix code, the ABI is there by default (and
design).  This (386) feature *is* what ABI is all about - the ability
to take a package from one 386 machine and run it on another one, even
if the Unix OS was bought from another vendor.

uPort vs. 386/ix compatiblity is there by DESIGN.
