A question about 386 binaries

[tony at joshua.math.ucla.edu]

I hope someone out there can answer this question:

Is it true that all bianries created under various different 80386 based 
UNIX/XENIX operating systems are fully portable; i.e will the program 
executables compiled on a Unisys 386 machine running Unix Sys V work 
(without modifications) under SCO Xenix 2.3.1 (on a 386 clone)?  

How about C libraries and object files, are they portable also?

Thanks in advance for all replies.
