Well, because C has no "bool" in the sense of Boolean variables, this
is rather irrelevant.

The "!" probably was literally meant as "not" but does not really do
it, it just acts like a "compare with zero", simulating a Boolean. :-)

So "!=" does not make sense from this point of view. One could argue,
its just the best "visual" replacement they could get for a "/=" what
could not be used because it was already meant to be a complete
different thing. ;-)
