[Message part 1 (text/plain, inline)]

Emacs is not deleting the auto-save-list file when closing. This happens
only if I set the auto-save-list file name with the
auto-save-list-file-name variable instead of with the
auto-save-list-file-prefix.

I can't reproduce on GNU/Linux this with:

emacs-24.3 -Q --eval '(setq auto-save-list-file-name "/home/gm/FOO")' ~/bar &

If I make some changes to ~/bar and wait for it to be auto-saved, ~/FOO
is created. If I save bar and exit Emacs with C-x C-c, ~/FOO is removed.

Do you have a recipe starting from emacs -Q?

Minimal working .emacs example

(defconst backups-dir "~/.emacs.d/backups/")

;; auto-save
(setq auto-save-default t
      auto-save-interval 0
      auto-save-timeout 5
      delete-auto-save-files t
      auto-save-list-file-name (concat backups-dir (format ".auto-save-%s"
(emacs-pid)))
      auto-save-file-name-transforms `((".*" ,backups-dir t)))


I run Emacs 24.3 on Windows 7 x64 with "runemacs.exe"

Thanks. My minimal example would be:

  (setq auto-save-list-file-name "~/SAVE")

> (defconst backups-dir "~/.emacs.d/backups/")

Use (expand-file-name "~/.emacs.d/backups/") and it should work.

The issue is that we use

   unlink (SSDATA (Vauto_save_list_file_name));

and unlink does not understand the "~" construct.

No, it's an Emacs bug that we should fix. Thank you for reporting it.
