It's probably helpful to note explicitly that these are not in arguments to
varargs functions,
in which case the explicit cast is needed in order to produce a program
that will have
correct behavior on all compliant compilers/systems.  (We do define NULL to
be a zero-with-cast,
but programs should not assume that NULL will be of pointer type -- "An
integer constant
expression with the value 0, or such an expression cast to type void *, is
called a null pointer constant".)
