  * This attempts to test all the possible variations of |operator==|
  * used with |nsCOMPtr|s.  Currently only the tests where pointers
  * are to the same class are enabled.  It's not clear whether we
  * should be supporting other tests, and some of them won't work
  * on at least some platforms.  If we add separate comparisons
  * for nsCOMPtr<nsISupports> we'll need to add more tests for
  * those cases.
