Btw, Al is fixing this. We'll make enum's properly typed, rather than just 
plain integers. It's not traditional C behaviour, but it gives you better 
type safety, and Al points out that other C compilers (the Plan 9 one, to 
be specific) have done the same thing for similar reasons.

So we'll eventually be able to use enum's instead of #defines without
losing any sparse information.

Of course, the only case where it matters is exactly cases like this, 
where the difference between using an enum and a #define is basically a 
matter of taste. But since I agree that enum's can look a lot nicer, it's 
good to know that it's being worked on.
