Yes, I think that would be OK also. I was just trying to offer more
alternatives, as you suggested that this change might be too drastic.
If programs suddenly start running slower at -O0, some people will
notice and complain, but I doubt that we really have to worry about this
unless there are very significant performance changes, and that seems
rather unlikely.
