Void* came out with the V7 compiler, if I recall properly. The BSD kernel
looks as if it requires such a later compiler (it uses bit fields which the
earlier compilers didn't support).
But it doesn't matter. You are right char* (or caddr_t) would work just
fine for this albeit with some explicit casting.
This appears to be incorrect, unfortunately. I just tested on the PDP-11/70
running 7th Edition at the Living Computer Museum (I've got an account
there) and it appears that neither `cc` nor `pcc` understand `void`.
Perhaps Steve Johnson can chime in on this? I suspect he'd know the history
here well.
