In the part of my posting which you deleted, I pointed out where the
standard deliberately does not define a cast null pointer to be a
null pointer constant, unless the cast is to void *.  Therefore the
compiler cannot take advantage at compile time of knowing that this
is a null pointer; it has to wait until execution time (or at least
it has to appear that way).  Execution-time null pointers do in fact
have a type which is known at compile-time.
