[Bug c++/16489] New: G++ incorrectly rejects use of a null constant integral expression as a null constant pointer

["gdr at gcc dot gnu dot org" <gcc-bugzilla at gcc dot gnu dot org>]

Consider

    const int NULL = 0;
    int main() { double* p = NULL; }

G++ incorrectly rejects the above.  This regression is also present
in GCC-3.3.x, in direct violation of the C++ standard.
