Hi again Shuah.

Thanks, this looks good to me now.

Here's just one new trivial bit.

Instead of giving a prototype to a static, can
you move the static to this location instead?

It's a trivial function that just enumerates
the int and returns a descriptive char *

btw: it should be declared "const char *" too.

That could be a new patch if you're tired of
modifying this one.

cheers, Joe
