wait3() is a BSD-ism.  It differs from wait(S) in that it will return the
status of any stopped processes (job control stop, that is).  Note that
since xenix doesn't have job control, there is little to no need for it.

On the other hand, POSIX has a routine called 'waitpid,' which can be made
into a wait3() via a macro.  SCO UNIX supports it (because it has job
control).
