Yeah, it's absolutely not safe.
What I'd suggest is declaring the actual variable as int. You can still
use an enum typedef to declare the values, and just avert your eyes
when you have to cast the enum to int or vice versa. (This is legal per
C spec, so you won't introduce any portability issues when you do it.)
