I heartily agree!  I've been rebuilding -stable since Monday, and
every time I run into a minor problem, I have to start again from
scratch.

Yes, this seems the way to go.

If the compiler's the reason for rebuilding, why not make the
libraries dependent on it?  It seems that a lot of the 'rm -rf's in
the Makefiles are the result of inadequate dependencies.  I would
suggest that we make the standard build ('make everything'?) without
any 'rm -rf', and gradually work on getting the dependencies correct.
