Sometimes a library can be an effective tool of pressure on vendors, but
I think in this case you have to change the design. It's not just an
issue of old vs new compilers. In general, even the new compilers don't
implement the MI optimization. Vendors are simply *not* going to break
backwards-binary-compatibility just to make our smart pointers smaller,
and smart pointers simply *must* be small.

IMO, of course ;-)
