The spec says that a warning should be issued if a variable declared to be ignored is declared SPECIAL, as in:

(defun foo (x y)
 (declare (ignore y))
 ...
 (locally
   (declare (special y))
   ...))

That code doesn't make much sense, but it clearly deservers a warning.

(defparameter y ...)

(defun foo (x y)
 (declare (ignore y))
 ...)

is about the same thing, but the warning in both cases should probably complain that inconsistent declarations applied to Y and not just say that it "wasn't IGNOREd".

rename-file filespec new-name should supply missing components of new-name from filespec, which it does wrong in the case of (rename-file (make-pathname :name "x.s") "y"). Presently CCL (1.8 and trunk on linuxx86) renames "x.s" to "y.s" because it resolves supplied filespec into its truename via intermediate conversion to a native namestring before supplying defaults.

This is a fix:

It appears that sometimes (prog1 x y) returns y. I've attached a file where CCL returns an incorrect value, perhaps for that reason. Version/platform info is in that file, but here it is:

1.9-dev-r15527M-trunk  (LinuxX8664)

[and from uname -a:]

As explained in the attached file, I didn't have this problem on a Mac for a slightly older CCL version.
