Why do you think it is inconsistent?

When NULL is used as a variadic argument, it must be cast to the proper 
pointer type.  This applies in both C and C++, but especially C++ users 
should expect to have to be much more careful about type-correctness and 
to include appropriate casts, and C++ requires NULL to be an integer.
