Rename the `len', `largest' and `max' members to `len_', `largest_' and `max_' to try and catch existing places that might directly modify these values. Make new accessors Dynarr_largest() and Dynarr_max() and make them and existing Dynarr_length() be non-lvalues by adding '+ 0' to them; fix a couple of places in the redisplay code that tried to modify the length directly by setting Dynarr_length(). Use the accessors whenever possible even in the dynarr code itself. The accessors also verify that 0 <= len <= largest <= max. Rename settor function Dynarr_set_size() to Dynarr_set_length() and use it more consistently; also create lower-level Dynarr_set_length_1(). This latter function should be the only function that directly modifies the `len_' member of a Dynarr, and in the process makes sure that the `largest' value is kept correct. Consistently use ERROR_CHECK_STRUCTURES instead of ERROR_CHECK_TYPES for error-checking code. Reintroduce the temporarily disabled verification code on the positions of Dynarr_at(), Dynarr_atp() and Dynarr_atp_past_end(). Also create Dynarr_resize_if() in place of a repeated code fragment. Clean up all the functions that modify Dynarrs to use the new macros and functions and verify the correctness of the Dynarr both before and after the change. Note that there are two kinds of verification -- one for accessing and one for modifying. The difference is that the modify verification additionally checks to make sure that the Dynarr isn't locked. (This is used in redisplay to check for problems with reentrancy.) * lrecord.h: Move XD_DYNARR_DESC to lisp.h, grouping with the dynarr code.

;;; 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
