And when the XEmacs 21.5 code base goes stable?  What then?  Is that
really as good as

    (if (not (emacs-version>= 21 5)) (require 'ess-site))

which right now has the same effect, but will have a different effect
when this code base becomes stable?

I also don't understand why 21.5 doesn't need ess-site, but that looks
very fishy to me.  If there's 21.4-specific code in ESS, I don't think
it belongs in a site config file, but rather in an appropriately named
compatibility library.

That is, although I see how it could be used to temporarily work
around the real issue (which is hidden in ess-site somewhere), it
seems to me you're storing up trouble for the future.
