bug#11735: 24.1.50; "Warning: Unknown defun property ... in ..."

[Drew Adams]

I load a library that I did not write, which does this:
 
(require 'cl)
(defun foo 
    (short full 
     short-index initial-full-index 
     chunks current-chunk current-chunk-pos 
     recurse-p)
  "..."
  (declare ;(optimize speed)
   (fixnum short-index initial-full-index)
   (simple-string short full)
   (special *all-chunks*))
 
Now I see this in *Messages*"
 
Warning: Unknown defun property fixnum in foo
Warning: Unknown defun property simple-string in foo
 
Is this a bug?
