Missing reset method in ...

Another problem I found is that the auto_ptr class misses the reset method implementation. A brain-dead solution is to derive a new class from the auto_ptr and add this reset implementation (taken from another MS STL):

void reset(_Ty* P = 0) {
  // destroy designated object and store new pointer
  if (_Ptr != P)
    delete (_Ty *)_Ptr;
  _Ptr = P;
  _Owns = (P != 0);
}
