Keep a dir at the top of load-path??

Keep a dir at the top of load-path??

[ned]

I have built a handy .emacs that lets me run either Emacs or XEmacs
depending on my mood.  

The only problem is that I want to byte-compile my various .els with
one or the other.  I want to specify an Emacs byte-compile destination and an
XEmacs destination and have them be called first from the load-path.  

So the question is how to keep an entry as the first entry in
load-path no matter what gets added subsequently.

Does that make sense?

Maybe not quite what you want but does this help?

(defmacro dh-when-xemacs (&rest forms) ;; (declare (indent 0))
  (when (featurep 'xemacs) (cons 'progn forms)))

(defmacro dh-when-gnu-emacs (&rest forms) ;; (declare (indent 0))
  (unless (featurep 'xemacs) (cons 'progn forms)))

(defvar dh-elisp-dir
  (concat "~/.elisp/"
          (dh-when-xemacs "xemacs/")
          (dh-when-gnu-emacs "emacs/")
          "/"))

(dolist (path (list dh-elisp-dir
		    (concat dh-elisp-dir "maxima/")
		    (concat dh-elisp-dir "http-emacs/")
		    (concat dh-elisp-dir "slime/")
		    (concat dh-elisp-dir "bbdb/lisp/")
		    (concat dh-elisp-dir "erc/")))
  (dh-add-path path 'load-path))
