It was a typedef, otherwise 'caddr_t a, b' would not have done the expected
thing.

I also suspect that some of the code might have wanted a pointer to
volatile data, but many want a volatile pointer.
I started trying to 'fix' the code in src/sys/arch/amiga/dev/grf* but
I suspect it is all broken though...
