I've been maintaining bindings to multiple C libraries (including 
Freetype 2 bindings) for 13 years now. I have never encountered 
an issue with an enum size mismatch. That's not to say I never 
will.

I would say it's something you just don't have worry about. If, 
at some future time, any C compiler on any platform decides to 
start treating enums as something other than int or uint by 
default, then we can report a bug for D and fix it.
