I want to be able to do both. Also as far as I remember not having to ship builtin_function.cpp in the tarballs was the reason why builtin_compiler was added in the first place. So I really want this to be fixed properly. Heh, this sounds as if I was the only person around that wants to cross-compile Mesa, but I suspect that's not the case. =) Thierry
