>From Patrick Schluter:

- enum constants bigger than uint. Full in undefined behaviour territory
according to the standard, gcc defines the behaviour and defines enums as
long/unsigned long/long long/unsigned long long if necessary. ImportC rejects
for instance

Error: enum member `lang.LANID_TYPE.LANID_GL` enum member value `4294967296LU`
does not fit in an `int`
