That means you have to follow what is going on the mainline closer than you would if you just branched the whole sources. Yes changes like this has happened for 4.2.0 even. Since you branched the GCC directory for non front-end changes like say a new opimization, you don't want to follow what is happening on the C++ front-end side that closely .Also you don't know if it was too late to update until you actually did it.
