What's the point of these flags? (or to be more precise, are they really justified whenever they are used?) Usually the set of cpu instructions should be controlled by your CFLAGS, and I've been actively patching packages (that do not do manually coded assembly) to make such flags unnecessary. -- Andreas K.
