The only reason to do that is because you need to map to something like 
hardware where this is required, so it's a fairly rare case (what I 
called the edges of software). Even then, there's no advantage to using 
a derived type. Indeed, using a derived type is giving contradictory 
information to the compiler: "use the same representation as Integer" 
and "use only N bits".
