Can I declare ignore a global?

[poeck@informatik.uni-wuerzburg.de (Karsten Poeck)]

I tried to compile a Clos benchmark from Ken Anderson in MCL and run into
the following problem. When I define a global variable <the global> and a
function that has <the global> as a parameter I cannot do (declare (ignore
<the global>)).

Test code follows. 

Is this a bug in MCL 2.0.1 or is the declaration illegal?

(defvar dummy-global)

(defun test (dummy-global)
  (declare (ignore dummy-global))
  1)
