I was annoyed by that just the other day on an Alpha box (it provokes
lots of "integer cast to pointer of different size" warnings there).
I'm sure the use of caddr_t is strictly historical.

If you feel like doing something about it, changing the arguments of
these routines to be Datum and then adding the necessary
to-and-from-Datum macros seems like the obvious solution path.
