Hang on a moment, are you saying that all the people writing to argue
that these changes would require them to write dozens more #ifdef's
actually don't have to write any at all? I never knew what the *-compat
packages were all about. If that's what they're designed to do, I have a
feeling they have not gotten *nearly* enough exposure.
