Such code is broken because conforming implementations may use the integer
type: NULL cannot be used uncast as a variadic argument (and in principle
we could detect the use of the NULL macro in such a case and warn for it).
Thus the warning, detecting broken code with an uncast NULL (as was in an
example in a POSIX draft until the problem was pointed out and fixed), is
appropriate.
