Hmmm.  "Extra files" would mean "file that _is_ there but _should_not_
be there", while the actual error message would seem to indicate that
the "file bfd.h _is_not_ there but _should_ be there".

In either case I ran the sugggested ``cvs up'' command (with the -q
option, to avoid the plethora of "Updating <dirname>" messages) and
nothing out of the ordinary shows up.

I probably ought to mention a couple more items:

* This happens in two separate sources trees, and
* it happens with a completely empty TOOLDIR (and OBJDIR and DESTDIR)
