No. Well, that is simple enough to find out.. git show 77433830ed164 just tells us. Of course, that also points to scripts/Makefile.lib, which doesn't have this problem, because it keeps c_flags and a_flags nicely separated. Anyway, that just makes me think that something like that patch in my previous email is the way to go, but I would like to stress (again) how little testing it had: exactly none. So please consider that nothing more than a hand-wavy "something like this". Linus
