Hi,
when compiling BBDB with Emacs 22.2 or newer, I get the following
warning:
,----
| Compiling file [...]/bbdb/lisp/bbdb-whois.el at Sun Apr 13 14:12:13 2008
| bbdb-whois.el:25:1:Warning: !! The file uses old-style backquotes !!
| This functionality has been obsolete for more than 10 years already
| and will be removed soon. See (elisp)Backquote in the manual.
`----
,----[ (info "(elisp)Backquote") ]
| In old Emacs versions, before version 19.29, ``' used a different
| syntax which required an extra level of parentheses around the entire
| backquote construct. Likewise, each `,' or `,@' substitution required
| an extra level of parentheses surrounding both the `,' or `,@' and the
| following expression. The old syntax required whitespace between the
| ``', `,' or `,@' and the following expression.
|
| This syntax is still accepted, for compatibility with old Emacs
| versions, but we recommend not using it in new programs.

(defmacro bbdb-add-to-field (record field text)
(let ((get (intern (concat "bbdb-record-" (symbol-name field))))
(set (intern (concat "bbdb-record-set-" (symbol-name field)))))
(` (let ((old ((, get) (, record)))
(text (, text)))
(or (member text old)
((, set) (, record) (nconc old (list text))))))))
--8<---------------cut here---------------end--------------->8---
IIRC in all packages bundled with Emacs, the use of old style
backquotes have been fixed.
