check that the version stamps in 'unit' and the version stamps of the units in 'base' are consistent. If they are, 'base' is updated to include 'unit' and NIL is returned, otherwise 'base' is left unmodified and the list of inconsistent units is returned. If there are inconsistencies, error messages are written on 'errors'. If 'errors' is NIL, the error messages are silently dropped. It is an unchecked runtime error to modify any of the units or their referents once they've been merged with 'base'.
