On the trunk it's already fixed:

  ;; A dummy process to keep comint happy. It will never get any input
  (unless (comint-check-proc (current-buffer))
    ;; Was cat, but on non-Unix platforms that might not exist, so
    ;; use hexl instead, which is part of the Emacs distribution.
    (condition-case nil
        (start-process "ielm" (current-buffer) "hexl")
      (file-error (start-process "ielm" (current-buffer) "cat")))
    (process-kill-without-query (ielm-process))
    (goto-char (point-max))
    

I'd suggest doing the same for EMACS_21_1_RC.
