Hi

When building canadian cross compiler, I have some trouble with
configure defining caddr_t as a macro, like

#define caddr_t char *

When combined with the types.h where caddr_t is protected together with
daddr_t, the typedef of caddr_t breaks.

This patch works around it by protecting the caddr_t typedef
specifically.

I am uncertain as to the real cause and solution to this :-(

Anyways, if you get problems with caddr_t in types.h, you might want to
try this.
