Using XEmacs 21.1.8, I updated all the packages today. When I edit a file using make-mode, I get the following error: File mode specification error: (void-function regexp-opt) I looked in make-mode.el and, indeedm it invokes (regexp-opt) but the function does not seem to exist anymore. What's going on?
