To rebuild XEmacs then requires recompiling "help", "list-mode", and a number of package files including a couple of "psgml" and others (any library using `define-derived-mode' to be precise). The recompiled libraries now no longer work with any previous XEmacsen. -- Jens-Ulrik Holger Petersen <http://www.kurims.kyoto-u.ac.jp/~petersen/> Research Institute for Mathematical Sciences, Kyoto University
