Stabilization of GCC is especially careful because if your GCC winds up broken, you might not be able to fix it (emerge won't work). And since GCC is used to build everything else on your system, it can't go stable until all upstream packages are fixed or patched to work with the new GCC. There's usually a tracker for those packages. For gcc-4.9 it's at, https://bugs.gentoo.org/show_bug.cgi?id=gcc-4.9
