Under Xenix '386, I get: 2, 0, 2, 0; using the '286 compiler, I get 0, 0, 2,
0.  So, anybody, what does ANSI say (in plain English)?  I tried reading the
draft to see what it should be, and I couldn't make head nor tail of it...
Somebody said, earlier, that both K&R and ANSI say the results are
implementation defined, but, from what I could stand of the draft, it didn't
seem to say that.
