It seems such a simple concept. It should never be signed, so let's just treat it as unsigned. Except if it goes unsigned, the same problems develop as if when it is signed. So the rule remains the same. This is the same mess that happened with ssize_t and size_t. A better rule would have been to restrict both sizes to the same limit. But no..... we assume people can be careful, or the little 'u' which avoids a warning will make things better
