(2) printing_unreadable_lcrecord -> printing_unreadable_lisp_object and fix up so it no longer requires an lcrecord. These previous changes eliminate most of the remaining places where the terms `lcrecord' and `lrecord' occurred outside of specialized code. (3) Fairly major change: Reduce the number of words in an lcrecord from 3 to 2. The third word consisted of a uid that duplicated the lrecord uid, and a single free bit, which was moved into the lrecord structure. This reduces the size of the `uid' slot from 21 bits to 20 bits. Arguably this isn't enough -- we could easily have more than 1,000,000 or so objects created in a session. The answer is (a) It doesn't really matter if we overflow the uid field because it's only used for debugging, to identify an object uniquely (or pretty much so). (b) If we cared about it overflowing and wanted to reduce this, we could make it so that cons, string, float and certain other frob-block types that never print out the uid simply don't store a uid in them and don't increment the lrecord_uid_counter. (4) In conjunction with (3), create new macro NORMAL_LISP_OBJECT_UID() and use it to abstract out the differences between NEWGC and old-GC in accessing the `uid' value from a "normal Lisp Object pointer". (5) In events.c, use zero_nonsized_lisp_object() in place of custom- written equivalent. In font-mgr.c use external_object_printer() in place of custom-written equivalents.

;;; site-load.el --- Template file for site-wide XEmacs customization
;; Copyright (C) 1997 Free Software Foundation, Inc.

;; Author: Steven L. Baur <steve@xemacs.org>
;; Keywords: internal

;; This file is part of XEmacs.

;;; Commentary:

;; This is a prototype site-load.el file.
;; The site-load.el mechanism is provided so XEmacs installers can easily
;; dump lisp packages with XEmacs that do not get dumped standardly.

;; The file `site-packages' if it exists should look something like:
;; (setq site-load-packages '(
;; "../lisp/modes/cc-mode.elc"
;; "../lisp/utils/redo.elc"
;; "../lisp/packages/scroll-in-place.elc"
;; )
;; )

;; The first line and the last line must be exact.  Each of the packages
;; listed must be double quoted, have either an absolute path, or a relative
;; to the build src directory path *and* be bytecompiled prior to the attempt
;; to dump.  They also must explicitly have the .elc extension.

;; Because this is a trial implementation and the file is shared with
;; make-docfiles, syntax is strict and unforgiving.  So sue me.  It
;; is still better than the way it used to be.

;; Also note that site-packages belongs in the top level directory not the
;; lisp directory for use with --srcdir configurations.

;;; Code:
(defvar site-load-package-file "../site-packages"
  "File name containing the list of extra packages to dump with XEmacs.")
(defvar site-load-packages nil
  "A list of .elc files that should be dumped with XEmacs.
This variable should be set by `site-load-package-file'.")

;; Load site specific packages for dumping with the XEmacs binary.
(when (file-exists-p site-load-package-file) 
  (let ((file))
    (load site-load-package-file t t t)
    ;; The `pureload' macro is provided as a clue that a package is
    ;; being loaded in preparation of being dumped into XEmacs.
    (defmacro pureload (file)
      (list 'prog1 (list 'load file) '(garbage-collect)))
    (message "Loading site-wide packages for dumping...")
    (while site-load-packages
      (setq file (car site-load-packages))
      (pureload file)
      (setq site-load-packages (cdr site-load-packages)))
    (message "Loading site-wide packages for dumping...done")
    (fmakunbound 'pureload)))

;; This file is intended for end user additions.
;; Put other initialization here, like setting of language-environment, etc.
;; Perhaps this should really be in the site-init.el.

;;; site-load.el ends here
