malloc (sizeof *nodeptr) helps catch foolish errors. This is one of
the secondary reasons not too use superfluous parens with the sizeof
operator: when you see them you know there is probably something not
quite right (like here, should not repeat the type, it is too easy to
make errors that way).

"unt" is nice imo :-)

You you need this in the header? You could just say
enum rbt_color;
and nothing more?
Okay for trunk, whatever you decide to do for these. Thanks!
