Byte compiling and semi-free variables

["Lennart Borgman" <lennart.borgman@gmail.com>]

If you order definitions top-down in your elisp source files, like this

  ;;;; Interactive defuns:

  (defun my-fun ()
    (interactive)
    (setq my-internal-var 1) )

  ;;;; Internal variables
  (defvar my-internal-var nil)

and byte-compile the files you get warnings like

  my-lib.el:118:14:Warning: reference to free variable `my-internal-var'

Is there any way to avoid that warning?
