Before Emacs 21.1, redefining these functions was dangerous and had
subtle misfeatures as side-effects.  Emacs 21.1 introduces
user-customizable options `backup-directory-alist' and
`make-backup-file-name-function'; please use them instead of what you
did before.

If you already tried to customize `make-backup-file-name-function' and
it didn't work, please send the details (how did you define the
replacement function, how did you set the value of
`make-backup-file-name-function' to point to your replacement, and
what did Emacs do in response.
