I'd have to see that code, also.  The system I am using to post this
article from is running IBM XENIX 2.0 and it doesn't have any problem
with code of the sort you're talking about here; perhaps that was a bug
in the 1.0 release, but not this one.  The area that I _have_ had a lot
of problems with is the curses library, but certainly not the standard
library.  The compiler also has a few minor problems, some of which
were addressed in the maintenance releases; perhaps the (somevalue)
expression wasn't very portable, but I can't be sure.

IBM used the Microsoft 3.0 release, which is a System V.something
derivative.  I can always get stuff written for Vr2 to work, and most
Vr3 stuff to work, provided I don't have any massive memory requirements
to work around.
