I, however, agree.  If the warnings are worth cleaning up, they'll get
cleaned up.

The BSD folks will immediately notice any make problems, I suspect.
The thing you are suggesting sounds better than what we have now, so I
think we should press forward.  I think we should also remove any
Makefiles in the front-end directories; they will probably not work
quite consistently anyhow.  You can always say `make jc1' in the `gcc'
directory anyhow.  We could even have a `make java' or `make cp'
targets, if required.
