I wrote a quick fix for it.  But I'm not sure if this is the best approach:

diff --git a/lisp/emacs-lisp/bytecomp.el b/lisp/emacs-lisp/bytecomp.el
index 392f6ee..d2bbefa 100644
--- a/lisp/emacs-lisp/bytecomp.el

     (when level

Not sure if there is a good solution for this.  The warning levels are 
predefined in the variable `warning-levels'.  They could be changed to lower 
case but that would break cases when there is no prefix.
