gcc's __attribute__(()) works right in some cases, but not here:
enum foo { ONE, TWO } __attribute__((__mode__(__QI__)));
tells you that __attribute__(()) doesn't apply to types.
enum foo xxx __attribute__((__mode__(__QI__)));
gives an ordinary enum.
enum foo xxx __attribute__((__mode__(__DI__)));
gives a long long enum.
I often store enums in char variables and interpret the
char variables in debuggers by casting back to enums.
