This is just a warning. You can safely ignore it.

I think this has been fixed in CVS.  If you don't want to switch to
the CVS version, but are willing to patch your swank-clisp.lisp here's
the current definition:

(defun fspec-pathname (symbol)
  (let ((path (documentation symbol 'sys::file))
	lines)
    (when (consp path)
      (psetq path (car path)
	     lines (cdr path)))
    (when (and path
	       (member (pathname-type path)
		       custom:*compiled-file-types* :test #'equal))
      (setq path
	    (loop for suffix in custom:*source-file-types*
	       thereis (probe-file (make-pathname :defaults path
						  :type suffix)))))
    (values path lines)))

The bug was triggered by a change from CLISP 2.34 to 2.35.  Maybe your
older cygwin had an older CLISP.
