Description:
------------
It is possible to redefine NULL (however, not null). No one probably does that but it should not be
possible. Maybe there are more of this kind of errors.
Test script:
---------------
var_dump(null); // null
var_dump(NULL); // null
define("NULL","hello world");
var_dump(null); // null
var_dump(NULL); // hello world
define("null","hello world"); //Notice: Constant null already defined
