    generalized-boolean.  CLX originally defined the boolean type to be a
    generalized boolean, however ANSI CL introduced a more restrictive
    boolean type (or nil t) which had been used by clx which broke code
    passing generalized booleans.  Since the generalized-boolean type is
    equivalent to T the declarations could have been flushed, but are
    retained for documentation purposes.
