My proposed patch says "When selecting a register, choose one that is
normally saved and restored by function calls on your machine. This
ensures library routines which are unaware of this reservation will
restore it before returning."  This platform-neutral statement seems to

Let's go with your platform-neutral statement. *If* someone comes backwith real world feedback on this stuff, we can always update.
