If you add a new type, it needs to be defined correctly and
portably - here, it obviously needs to follow the definition of
size_t (which isn't a typedef of "unsigned int" unilaterally).

With ssize_t in particular I have always been wondering what
benefit it provides over ptrdiff_t (i.e. whether there are
environments where the two could sensibly be different).
