AFAIK, rvalue references are not yet available in any branch. Of course 
are forthcoming, a patch is being finalized. This is the last version, I 
think:

    http://gcc.gnu.org/ml/gcc-patches/2007-04/msg01658.html

Anyway, for your type of work, maybe you should fetch cxx0x-branch:

    http://gcc.gnu.org/projects/cxx0x.html

... and / or keep in touch with Doug!
