Thanks for the heads-up. I'd rather leave those changes to the m68k
folks though. What you say might make more sense (I've no opinion
either way) but it would have been just as easy to do it that way using
the old TARGET_SWITCHES definition. Someone might have decided that the
current set-up was better for some reason.
