FWIW, I'm a big fan of RAII and I like the idea being able to
rely on a smart pointer in GCC quite a bit.  Although I haven't
reviewed the C++ 03 implementation in any detail I like how the
new API is just transitional until GCC switches from C++ 98 to
C++ 11 when it will be possible to drop it, presumably with no
changes to client code.  (If there's any risk that clients might
come to depend on the C++ 03 "features" or limitations in the
meantime and thus jeopardize this goal I would only suggest to
put some effort into making this harder.)

Other than that, thank you for this nice enhancement!
