bug#11241: 24.1.50; emacs-lock is ill uncompiled (lexical binding problem?)

Not really, if you look at the macroexpansion of the define-minor-mode-call

  (defun emacs-lock-mode (&optional arg)
    "..."
    (interactive (list (or current-prefix-arg 'toggle)))
    (let ((#1=#:last-message (current-message)))
      ((lambda (mode) (emacs-lock--set-mode mode arg))
      ...

Yes

Stefan, I can "fix" this for 24.1 just by making emacs-lock.el not use
lexical-binding. But is this difference between compiled and
non-compiled code a bug in the lexical-binding support or something
expected?
