The attached patch fixes this, perhaps not in the best fashion, here
is the description:

contrib/slime-parse.el (slime-make-form-spec-from-string):
Added (set-syntax-table lisp-mode-syntax-table), because of this:
(with-temp-buffer
  (erase-buffer)
  (set-syntax-table lisp-mode-syntax-table)
  (insert "'foo")
  (goto-char 1)
  (thing-at-point 'sexp)) => "'foo"

Without set-syntax-table it returns nil. This fixes (make-instance 'foo C-c C-s

(slime-parse-sexp-at-point): remove unused flets.
