   But less<> of the underlying pointer implements an *unspecified* strict   
   weak ordering, which is just another way of saying that the actual order   
   itself is meaningless.

   Which is basically the same question that the OP asked about his own   
   type.  He wants to give his type a strict weak ordering, and I   
   recommended he do it via operator<.
