Actually, after some more work, there's an anomaly when compiling RC1
with VisualAge C.  (I'm not sure if it bit earlier 7.4 releases; this
is the first time I have tried 7.4 with VAC/VACPP.  There were no
issues when I compiled 7.3.4 with VAC/VACPP.)

'CC=/usr/vac/bin/xlc'

======================================================================

So long as we're not expecting integrability of anything, I'm game for
-0 to be treated as mostly-equivalent to 0.

With VisualAge C++ *'CC=/usr/vacpp/bin/xlc'), I see the very same
result as with VAC.

This _seems_ a cosmetic difference, or am I way wrong?
