redef controls whether the "redefining var" warnings are displayed. I changed the safeset macro thus at the start of arc.arc:

  (assign disable-redef-warnings* nil)
  (assign safeset (annotate 'mac
                    (fn (var val)
                      `(do (if (is nil disable-redef-warnings*)
                           (if (bound ',var)
                               (do (disp "*** redefining " (stderr))
                                   (disp ',var (stderr))
                                   (disp #\newline (stderr)))))
                           (assign ,var ,val)))))
