   I don't believe that would solve anything really, because we are
   still trying to collapse two different types (regardless of its
   machine representation) in one. The same would happen with 'int'
   (for which we do have differentiated its signess).

Well, what we need is to operate on unsigned chars (values 0 -
255). The problem is to have to cast the (char *) arguments in systems
where char is signed by default.
