[PATCH] fix compilation on emacs23

[Mark Walters]

The series so far does not compile on emacs23. The two problems are
that cl-lib doesn't exist and that defvar-local is not defined. The
latter can trivially be replaced by defvar followed by
make-variable-buffer-local.

For the former just require 'cl as we do elsewhere, and change the one
call to a cl function, namely to cl-case to case.
---
Lightly tested and seems to compile and work on emacs 23 and emacs 24.

Best wishes

Mark
