Oh, that may be a difference between us.  As far as I'm concerned,
what happens in this case is both defined enough and clear enough
(for purposes of comp.lang.c) so that there's no question about
what's supposed to happen.  I agree that the Standard could do a
better job of expressing this, but not so much that anyone who
wants to understand what semantics are dictated is likely to be
misled.  Let me ask it as a question:  how likely is it (in your
opinion) that someone reading the Standard will reach a wrong
conclusion about what the behavior should be in such cases?
