Along these lines, I also am a little foggy on unions. This:
http://docs.racket-lang.org/foreign/C_Union_Types.html
says, "Unions are always treated like structs." But I have no idea what
that phrase means. I don't get the impression that unions have tags like
structs can have. Or can they? Mayb
Maybe a ctype which is a delay node, along the lines of
'recursive-contract', is the right thing here.

The forward reference is actually in wl_message, like this:

This isn't perfectly satisfying, but one option is to use a different
name for the forward declaration:
(define _wl_int
