This last statement is incorrect, or rather, evidence of a broken
compiler.

C requires that the integer constant 0 be assignable to *any* pointer
type.  C also requires that any pointer type may be compared with the
integer constant 0.  If the Xenix compiler requires that the integer
constant 0 be cast to a pointer type first, it is broken.
