    system definition using :READ-FILE-FORM or :READ-FILE-LINE, ASDF would

    a depended-on system has had its version number bumped and now satisfies
    a new :VERSION requirement).
    This was fixed by adding ADDITIONAL-INPUT-FILES to the object model.
    These serve the purpose of giving a place other than INPUT-FILES for ASDF
