Hi Zajcev, I intend to commit some changes to 21.5 soon that won’t work without this change. As a bonus, the bytecode is slightly nicer under SXEmacs and XEmacs 21.4:-) . Bye, Aidan xemacs-packages/xwem/ChangeLog addition: 2009-08-13 Aidan Kehoe <kehoea(a)parhasard.net&gt; * lisp/xwem-battery.el: * lisp/xwem-clients.el: Don't call values-list from compiled code if compiling without C-level multiple value support, avoiding problems when such compiled code is called in an XEmacs with C-level multiple value support.
