The trouble with using "caddr_t" to do the "void *" job is that "caddr_t"
is just a human convenience.  Depending on how you do it, "caddr_t" is
either a #defined symbol or a typedef; neither is any more than an
abbreviation for some other type.  Strict type checking will expand the
abbreviation and then complain about the expansion.

I suppose one could make "caddr_t" a magic keyword, but using "void *"
is simpler and doesn't introduce a new keyword.
