Well, to my knowledge, CCS C is an Ansi compiler.  If so, it should follow the
ansi C spec.

IIRC, when doing a comparison between two variables which are not explicitly
cast, they are both converted to the 'next higher' variable, which would be a
signed long.  If that was the case, your comparison would be fine.

Since that is not the case, than one of my two assumptions are incorrect (either
CCS is not ansi in this respect, or ANSI does not require a specific method of
casting variables when doing compare operations).

At any rate, since you know that your signed int cannot possible ever go above
250, why even make the comparison?  I'm assuming it's just to demonstrate the
problem.  Is there a reason why you can't define them both as the same type of
variable?
