 TBH I don't understand what you mean here, a C compiler is free to choose 
from `char', `int' and `unsigned int' as the underlying (compatible) type 
of an enumeration as long as the type can represent all the member values 
defined.  How exactly the signed `int' type is going to be advantageous 
over the `unsigned int' type here?  If this is used to produce a bit mask, 
which I gather it is, then I find using an unsigned type more natural.
