On 32-bit architectures, there is no problem. // On 64-bit architectures, defining NULL as a 32-bit constant can cause // problems with varargs functions: C++ integral promotion rules say for // varargs, we pass the argument 0 as an int. So, if NULL was passed to a // varargs function it will remain 32-bits. Depending on the calling // convention of the machine, if the argument is passed on the stack then // only 32-bits of the "NULL" pointer may be initialized to zero. The // other 32-bits will be garbage.
