Is the default gcc in distro 4.9 now? It would be good to merge, yes, but we also need to merge the 4.9 unity-api. And, once we've done that, there will essentially be no going back :-)

The (now inappropriately named) set-env-vars should also be merged in the same batch, because it adds another virtual to AbstractScopeBase.
