21.4 and 21.5 compatiblity (missing functions)

Hello I would like to use 21.5, but all the time I tried[1], my favourite package x-symbol did not work. So I am stick to 21.4.X but I also want to use org mode (which in my opinion should be provided as a Xemacs pkg, once the GPL3 problem is solved.) However org uses a bunch of functions which are defined for 21.5 but not for 21.4.X I have found so far 2: - decompose-region - replace-regexp-in-string Both run without problems in 21.4.X So the question arise, can't 21.4 not have a xemacs21.5-compat pkg which contains all the new lisp functions, which could work under 21.4 regards Uwe Brauer Footnotes: [1] I will try the latest 21.5 version today, see my next post _______________________________________________ XEmacs-Beta mailing list XEmacs-Beta(a)xemacs.org http://lists.xemacs.org/mailman/listinfo/xemacs-beta
