I will change it to a range of GCC versions stopping at either 4.9.0 or 4.9.1 for now.
Will also start at 4.7.2 (the web implies it might have started with that version.)
Will post when I get it done.

I have pushed the change; the undef should stop at 4.9.0; so GCC 4.9.1 will result in PCH size crash if bug not fixed by then.
