On second tought, it occurs to me that in mainline we have now:

      struct _Rep_base
      {
        size_type         _M_length;
        size_type         _M_capacity;
        _Atomic_word        _M_references;
      };

      struct _Rep : _Rep_base
      {
        ...

 From a practical point of view is 8670 still an issue? Or the
library people can wait for the front end changes?
