Oh man, it's kinda crazy that the compiler is changing in a way that the
same piece of code can't be compiled the same way across two adjoining
versions of the same compiler. But, yeah, if that's what gcc is gonna do and
splitting enums is the only way to be okay across the compiler versions,
there isn't any other choice we can make.

Thanks.
