you are not serious, are you?
We are not supposed to patch Emacs 21.1 but rather have ESS work with it!

Has any body got a solution in the mean time?
(and anybody by chance found an w3/emacs version that properly works with
 Emacs 21.1 ?)

We would like to release an ESS version 5.1.20 that at least *works* with
Emacs 21.1...
