I used the Emacs from Debian:

(emacs-version) =>
"GNU Emacs 21.4.1 (i386-pc-linux-gnu, X toolkit, Xaw3d scroll bars)
 of 2005-03-17 on trouble, modified by Debian"
(fboundp 'defvaralias) => t

and also:

,----[ src/ChangeLog.9 ]

| 
| 	* (Version 21.1 released.)

|
| 	(Fdefvaralias): New function.

But I overlooked an earlier:

,----[ src/ChangeLog.9 ]
| 2001-10-04  Gerd Moellmann  <gerd@gnu.org>
| 
| 	* Branch for 21.1.
`----

and I found out that the Big Brother Database does:

,----[ bbdb.el ]
| (unless (fboundp 'defvaralias)
|   (defun defvaralias (&rest args)))
`----

I guess it ain't called insidious for nothin'.

Sorry for the noise,

  Lute.
