I understand your concern, but I would hope the gcc maintaniner would
notice any changes and give us a heads up. The question I think we
need to answer is are we willing to sacrifice performance on the
standard machines of today just to keep full compatibility with 10
year old machines? When the time comes that packages will no longer
run at all on older machines, we may have to provide separate packages
