(From another strand of this thread) I don't think the -P option to the
cvs update command does this, it just prunes empty subdirectories, and
-d does roughly the opposite. If cvs has a way to delete files that are
not in the archive I have never found it, and would be curious to know
what it is so that I can be careful to avoid it.

This is probably the answer, but I don't understand how it solves what I
think was the original question. Could someone please expand on
i/ How make will know to ignore certain .o files which should not be
there, but leave other ones that are up-to-date and not rebuild them.
ii/ How to build R in a different directory from the sources.
