Indeed.  The Emacs wiki suggest that there is a Debian repo with Emacs
snapshots.

Yeah, but you get bufferf pointers.  As I hinted in my first post you can
write a boilerplate around it,

    (with-temp-buffer
      (save-excursion (insert (mapconcat 'symbol-name '(c b a á) "\n")))
      (sort-subr nil 'forward-line 'end-of-line nil nil
                 (lambda (a b) (funcall
                           (if (fboundp 'string-collate-lessp)
                               'string-collate-lessp
                             'string-lessp)
                           (buffer-substring (car a) (cdr a))
                           (buffer-substring (car b) (cdr b)))))
      (buffer-string))

But this seems like a lot of trouble just to get locale-aware sorting...
