phst Improve fix for #295
Requiring the legacy ‘cl’ library unconditionally pollutes the namespace.
Instead, require it only when compiling and in known-broken versions.

This is almost the same patch that opoplawski suggested, except that I removed
the test for ‘emacs-repository-version’, which isn’t defined in Emacs 24.3.
