If so, that is a recipe for pain (changed default c++ ABI), see e.g developer.redhat.com/2015/02/10/gcc-5-in-fedora/ : fedora-22 has, or will have (not sure of its release date) gcc-5, but _most_ packages will not be rebuilt. For those of us who build everything from source, this is one example where upgrading the default compiler on an existing system will probably cause extra problems.
I'll be tagging some more packages soon - I built mesa-10.5.3 and llvm with gcc-5 on a new system without problems. Can't tag mesa, we are now on 10.5.4, and I can't tag the general xorg-packages (except the protocol headers) because I don't usually build everything. But almost everything else (all except mdadm, xorg-server, qt-4 - fixes went in earlier) built ok. So, I'll be using gcc-5 on new builds, and continuing to use 4.9.2 to update packages on 7.7. ĸen -- Nanny Ogg usually went to bed early. After all, she was an old lady.
