Interfaces.C.Int'Size/8
Interfaces.C.Int is the same as C Int, but the Size attributes is in bits, not bytes (OK, I assume here that a byte is 8 bits :-).
Note that sizeof is *not* a regular function (a regular function could not have a type as the parameter). It is handled very
specially in the C compiler, therefore there is no way you could get to it from another language.
