bug#8554: 24.0.50; compiler warning after make-local-variable

["Andreas Röhler" <andreas.roehler@easy-emacs.de>]

emacs -q:

When `M-x byte-compile-file' the following form,

(defun highlight-indentation-on ()
   "Make sure `highlight-indentation' is on. "
   (interactive)
   (set (make-local-variable 'highlight-indent-active) nil)
   (highlight-indentation)
   (when (called-interactively-p 'any)
     (message "highlight-indentation ON")))

receive a warning saying:

In highlight-indentation-on:
highlight-indentation.el:47:55:Warning: assignment to free variable
     `highlight-indent-active'

That's not useful IMHO, as `make-local-variable' is explicit already.

Thanks


Andreas
