In my opinion, this is a C compiler bug.  The statement in question
adds two values of different enum types, but the ANSI standard
specifically says that names in enum types are "declared as constants
of type int", so the compiler must allow them to be used freely as
though they were ints.  I know of no other C compiler that forbids
this, although some compilers have similar, less serious problems of
this kind (e.g., not allowing a enum value to be used as the index in
a switch statement).
