port x-symbol to GNU emacs 24.

The following message is a courtesy copy of an article
that has been posted to gmane.emacs.devel as well.
Hello
The latest version of the x-symbol package is from 2003, but it still
provides useful features, especially for editing LaTeX files, I have not
seen in any other packages. Originally developed only for Xemacs, the
latest versions contain a GNU emacs specific file, x-symbol-emacs.el.
Moreover I do remember that it run under GNU emacs 21, although I forgot
the details.
Be it as it may, I tried to run x-symbol now under GNU emacs 24.4:
Byte compilation did not cause any problems but when I tried to load
the package I run into a series of problems, which I could only solve
partially.
- the function make-local-hook is not defined, I just copied its (xemacs)
definition into x-symbol-emacs.el (I attach its definition at the end
of the message and it seems to work.
- x-symbol-set-face-font: Wrong type argument: listp,
"-adobe-helvetica-medium-r-normal-*-14-*-*-*-*-*-iso8859-1"
although I had debug-on-error t, I did not obtain more details about
the error.
The definition of x-symbol-set-face-font is as follows
(defun x-symbol-set-face-font (face font charsets default)
(let ((fontset (concat "fontset-" (symbol-name face))))
(unless (query-fontset fontset)
;; We assume that the first time around we're using latin-8859-1
(new-fontset fontset
(x-complement-fontset-spec (make-vector 14 "*")
(list (cons 'ascii font)))))
(dolist (charset charsets)
(when charset (set-fontset-font fontset charset font)))
(set-face-font face fontset)))
But it seems GNU emacs 24.4 now treats fonts differently. Anybody has
a suggestion how to modify this function so that it is compatible with
24.4??
The next two errors are more serious.
- eval-buffer: Symbol's function definition is void: remove-specifier
[2 times] `Type C-x 1 to delete the help window, C-M-v to scroll help.
- eval-buffer: Symbol's function definition is void: map-extents
[2 times] `Type C-x 1 to delete the help window, C-M-v to scroll help.
Now both functions are built-in functions defined in C and I don't
know how to continue. Any changes of defining an alias for a similar function from
GNU emacs???
I really wounder how x-symbol could have worked with GNU emacs 21.
`map-extents' is a built-in function
-- loaded from "/home/oub/xemacs-mercury/xemacs/src/extents.c"
(map-extents FUNCTION &optional OBJECT FROM TO MAPARG FLAGS PROPERTY VALUE)
`remove-specifier' is a built-in function
-- loaded from "/home/oub/xemacs-mercury/xemacs/src/specifier.c"
(remove-specifier SPECIFIER &optional LOCALE TAG-SET EXACT-P)
Thanks and regards

Definition fo make-local-hook
(defun make-local-hook (hook)
The return value is HOOK.
You never need to call this function now that `add-hook' does it for you
if its LOCAL argument is non-nil.
When a hook is local, its local and global values
work in concert: running the hook actually runs all the hook
functions listed in *either* the local value *or* the global value
of the hook variable.
This function works by making `t' a member of the buffer-local value,
which acts as a flag to run the hook functions in the default value as
well. This works for all normal hooks, but does not work for most
non-normal hooks yet. We will be changing the callers of non-normal
hooks so that they can handle localness; this has to be done one by
one.
This function does nothing if HOOK is already local in the current
buffer.
Do not use `make-local-variable' to make a hook variable buffer-local."
(if (local-variable-p hook (current-buffer)) ; XEmacs
nil
(or (boundp hook) (set hook nil))
(make-local-variable hook)
(set hook (list t)))
hook)

Hi all,
The JDEE project appears to be coming back to life. There has been a
fair amount of discussion recently on their mailing list about a
reboot of the project. Lots of plans are being made. The question
has arisen as to whether they want their new effort to target both
Emacs and XEmacs, or just to target Emacs. Some are saying that
XEmacs support should be dropped, due to a perceived lack of interest
from XEmacs developers.
If any of you are interested in keeping JDEE going, join the discussion here:
