From 192ad63bd765d448e91389c6ff1d75f8b18bb268 Mon Sep 17 00:00:00 2001

Subject: More janitorial work: remove the explicit casting of NULL literals to
 a pointer type when it is not necessary to do so.

For future reference, casting NULL to a pointer type is only necessary
when (a) invoking a function AND either (b) the function has no prototype
OR (c) the function is a varargs function.
