In practice that is probably more of an issue with back end fixes
than front end fixes. Nearly all the front end fixes are clear, and
in any case the patch always includes appropriate comments. I am not
saying that following the above protocol would not be desirable, just
that in practice, we don't have the bandwidth to do much more than
the synchronization we are doing now. I do agree that general gcc
patches require appropriate documentation etc.
