site-run-file is a variable defined in `startup.el'.
Its value is "site-start"

the repertory is /usr/share/emacs/24.5/lisp/

but I now I have found


/usr/share/emacs/site-lisp/

which does not contain a site-start.el

but
  /usr/share/emacs/site-lisp:

hence we find an auctex in there (I recall from many years ago
that this has been for a long time in AUCTeX installs, before
I switched to ELPA)

;;; auctex.el
;;
;; This can be used for starting up AUCTeX.  The following somewhat
;; strange trick causes tex-site.el to be loaded in a way that can be
;; safely undone using (unload-feature 'tex-site).
;;
(autoload 'TeX-load-hack
  (expand-file-name "tex-site.el" (file-name-directory load-file-name)))
(TeX-load-hack)

I tried thus modifying my .emacs so


(cond ((>= emacs-major-version 24)
       (setq custom-file "/home/userX/.emacs.d/custom.el")
       (setq load-path (cons "/home/userX/.emacsaddons" load-path))
       (unload-feature 'tex-site);;; DON'T USE ANTEQUATED SYSTEM AUCTEX
       (load-file "/home/burnol/.emacs.d/init.el")
       (package-initialize)
       )
      )

and it works !

(I am on very tight schedule, I just initialized a bug-report from
a tex buffer and I get a window To: address@hidden Subject: 11.89.5; 
from which I deduced the problem is solved)

thanks for the help
