FYI: last week XEmacs in the CVS trunk (i.e. XEmacs 21.5-b28) came to byte compile the default value section of defcustom forms and report on undefined vars and functions found there. For instance: (defcustom foo (if (and (fboundp 'string-as-multibyte) default-enable-multibyte-characters) (string-as-multibyte "foo") "foo") "doc string") While compiling toplevel forms: ** reference to free variable default-enable-multibyte-characters While compiling the end of the data: ** the function string-as-multibyte is not known to be defined. (Emacs and XEmacs 21.4 don't do that.)
