Conditionalise the old-* functions and byte codes at compile time. src/ChangeLog addition: 2011-03-15 Aidan Kehoe <kehoea@parhasard.net> * config.h.in (SUPPORT_CONFOUNDING_FUNCTIONS): New #define, equivalent NEED_TO_HANDLE_21_4_CODE by default, describing whether this XEmacs should support the old-eq, old-equal and related functions and byte codes. * bytecode.c (UNUSED): Only interpret old-eq, old-equal, old-memq if SUPPORT_CONFOUNDING_FUNCTIONS is defined. * data.c: Move Fold_eq to fns.c with the rest of the Fold_* functions. * fns.c: * fns.c (Fmemq): * fns.c (memq_no_quit): * fns.c (assoc_no_quit): * fns.c (Frassq): * fns.c (Fequal): * fns.c (Fold_equal): * fns.c (syms_of_fns): Group old-eq, old-equal, old-memq etc together, surround them with #ifdef SUPPORT_CONFOUNDING_FUNCTIONS. lisp/ChangeLog addition: 2011-03-15 Aidan Kehoe <kehoea@parhasard.net> * bytecomp.el: Don't generate the old-eq, old-memq, old-equal bytecodes any more, but keep the information about them around for the sake of the disassembler. man/ChangeLog addition: 2011-03-15 Aidan Kehoe <kehoea@parhasard.net> * lispref/objects.texi (Character Type): * lispref/objects.texi (Equality Predicates): No longer document `old-eq', `old-equal', they haven't been used in years. tests/ChangeLog addition: 2011-03-17 Aidan Kehoe <kehoea@parhasard.net> * automated/lisp-tests.el: Only test the various old-* function if old-eq is bound and a subr.

;;; Synched up with: Not in FSF

;;; Commentary:

;; In FSF all of the custom loads are in a single `cus-load' file.
;; However, we have them distributed across directories, with optional
;; incremental loading.  Here we simply collect the whole set.


;;; Code:

(require 'custom)

(defun custom-add-loads (symbol list)
  "Update the custom-loads list of a symbol.
This works by adding the elements from LIST to the SYMBOL's
`custom-loads' property, avoiding duplicates.  Also, SYMBOL is
added to `custom-group-hash-table'."
  (let ((loads (get symbol 'custom-loads)))
    (dolist (el list)
      (unless (member el loads)
	(setq loads (nconc loads (list el)))))
    (put symbol 'custom-loads loads)
    (puthash symbol t custom-group-hash-table)))

(message "Loading customization dependencies...")

;; Garbage-collection seems to be very intensive here, and it slows
;; things down.  Nuke it.
(let ((gc-cons-threshold most-positive-fixnum))
  (mapc (lambda (dir)
	  (load (expand-file-name "custom-load" dir) t t))
	load-path))
