Thank you Mitch! I live on the same page as you, I hate the fact that C has a nice short word for signed integers and a much longer one for unsigned. Even with the newer sized types, I still need to add an extra 'u' in front of the signed type name. :-( Personally, I try to newer use signed ints unless it is really required. As an example, an interface where all returns are positive, except for -1 for an error, would still be better implemented as unsigned, with all bits set as the error value.
