To further elaborate: Portage takes care of passing -m32 and -m64 as necessary. Since you have a no-multilib system, it will never pass -m32 (and actually, never -m64 either, since we use a x86_64 compiler by default) and everything will be fine. That warning is there to keep people from overriding portage and breaking things. Daniel
