So you're effectively checking the size of the signed types to
determine which unsigned type to use as the unsigned 32bit type.  This
is only valid if we can assume sizeof(type) == sizeof(unsigned type).
Does the C standard conveniently guarantee this for us?

(Also, you'll want to provide a ChangeLog entry.)
