In addition, as I understand it: * openSUSE still has supported versions with gcc-4.7 * SLES (on older versions without 4.6 or 4.7) use a special stack of packages to build Firefox which includes gcc-4.7 * Ubuntu 12.04 LTS has 4.6, but are happy to build with a later version as long as there are no runtime issues * Older versions of RHEL are still on gcc-4.4, so they are already going to have to do something for Fx37 anyway and moving to 4.7 instead of 4.6 would probably not cause too much extra pain. I don't know how much more work moving to gcc-4.8 would cause, but it would certainly be some. Also, from what I can tell of the C++ features that gcc-4.8 enables (from [1]), none of them are available until MSVC 2015. It seems likely that we'll be supporting MSVC 2013 until the next ESR, so I don't see that moving to 4.8 gives us any immediate benefits.
