--- Comment #7 from Jonathan Wakely <redi at gcc dot gnu.org> --- That would be very welcome, thanks, Howard. We hope to complete the C++11 library for the next major release after 4.9, but there's still quite a lot to do. I haven't even analysed what we need to do to add move support to our streams (maybe Paolo has done).
