I agree: they should be on by default.  I'm not sure the options are a
good thing: Autoconf should provide an illusion of uniform behavior
accross hosts and packages.  If it doesn't suit a specific package for
some reasons, then it should probably be attached to a feature (some
functions?) rather than to CC.
