No, just the c++ programs, because they require the correct version of libstdc++, and that library is part of the gcc package. If the new gcc package includes a new version of libstdc++ (not always) then existing c++ apps will break because they can't find the old version of libstdc++. Note that the old libstdc++ will be reincarnated if you use gcc-config to switch back to the old version of gcc. Clear as mud?
