Except that function arguments of short and char are automatically
converted to type int except possibly when a function prototype is
given and it is not a variable argument.  (Whew!)  All three arguments
are (or should) be implicitly cast to int.  In this case, the compiler
thought that the last char was unsigned presumably because of the
function declaration.
