Hi All,

I tried to compile browse-kill-ring.el but it generates a few warnings
as follows:

,----
| In end of data:
| browse-kill-ring.el:1039:1:Warning: the following functions might not be
|     defined at runtime: gensym, delete-duplicates
| browse-kill-ring.el:1039:1:Warning: the function `browse-kill-ring-propertize'
|     is not known to be defined.
`----

Any ideas on how to get rid of these warnings? I have attached a copy of
browse-kill-ring.el for convenience.

Thanks,
--

;;; Commentary:

;; Ever feel that 'C-y M-y M-y M-y ...' is not a great way of trying
;; to find that piece of text you know you killed a while back?  Then
;; browse-kill-ring.el is for you.

;; This package is simple to install; add (require 'browse-kill-ring)
;; to your ~/.emacs file, after placing this file somewhere in your
;; `load-path'.  If you want to use 'M-y' to invoke
;; `browse-kill-ring', also add (browse-kill-ring-default-keybindings)
;; to your ~/.emacs file.  Alternatively, you can bind it to another
;; key such as "C-c k", with:
;; (global-set-key (kbd "C-c k") 'browse-kill-ring)

;; Note that the command keeps track of the last window displayed to
;; handle insertion of chosen text; this might have unexpected
;; consequences if you do 'M-x browse-kill-ring', then switch your
;; window configuration, and try to use the same *Kill Ring* buffer
;; again.

;;; Change Log:

;; Changes from 1.2 to 1.3:

;; * New maintainer, Nick Hurley <hurley@cis.ohio-state.edu>
;; * New functions `browse-kill-ring-prepend-insert', and
;;   `browse-kill-ring-append-insert', bound to 'b' and 'a' by
;;   default. There are also the unbound functions
;;   `browse-kill-ring-prepend-insert-and-quit',
;;   `browse-kill-ring-prepend-insert-and-move',
;;   `browse-kill-ring-prepend-insert-move-and-quit',
;;   `browse-kill-ring-append-insert-and-quit',
;;   `browse-kill-ring-append-insert-and-move',
;;   `browse-kill-ring-append-insert-move-and-quit'.

;; Changes from 1.1 to 1.2:

;; * New variable `browse-kill-ring-resize-window', which controls
;;   whether or not the browse-kill-ring window will try to resize
;;   itself to fit the buffer.  Implementation from Juanma Barranquero
;;   <lektu@terra.es>.
;; * New variable `browse-kill-ring-highlight-inserted-item'.
;;   Implementation from Yasutaka SHINDOH <ring-pub@fan.gr.jp>.
;; * `browse-kill-ring-mouse-insert' (normally bound to mouse-2) now
;;   calls `browse-kill-ring-quit'.
;; * Some non-user-visible code cleanup.
;; * New variable `browse-kill-ring-recenter', implementation from
;;   René Kyllingstad <kyllingstad@users.sourceforge.net>.
;; * Patch from Michal Maršuka <mmc@maruska.dyndns.org> which handles
;;   read-only text better.
;; * New ability to move unkilled entries back to the beginning of the
;;   ring; patch from Yasutaka SHINDOH <ring-pub@fan.gr.jp>.
;; * Do nothing if the user invokes `browse-kill-ring' when we're
;;   already in a *Kill Ring* buffer (initial patch from Juanma
;;   Barranquero <lektu@terra.es>).

;; Changes from 1.0 to 1.1:

;; * Important keybinding change!  The default bindings of RET and 'i'
;;   have switched; this means typing RET now by default inserts the
;;   text and calls `browse-kill-ring-quit'; 'i' just inserts.
;; * The variable `browse-kill-ring-use-fontification' is gone;
;;   browse-kill-ring.el has been rewritten to use font-lock.  XEmacs
;;   users who want fontification will have to do:
;;   (add-hook 'browse-kill-ring-hook 'font-lock-mode)
;; * Integrated code from Michael Slass <mikesl@wrq.com> into
;;   `browse-kill-ring-default-keybindings'.
;; * New Japanese homepage for browse-kill-ring.el, thanks to
;;   Yasutaka SHINDOH <ring-pub@fan.gr.jp>.
;; * Correctly restore window configuration after editing an entry.
;; * New command `browse-kill-ring-insert-and-delete'.
;; * Bug reports and patches from Michael Slass <mikesl@wrq.com> and
;;   Juanma Barranquero <lektu@terra.es>.

;; Changes from 0.9b to 1.0:

;; * Add autoload cookie to `browse-kill-ring'; suggestion from
;;   D. Goel <deego@glue.umd.edu> and Dave Pearson <davep@davep.org>.
;; * Add keybinding tip from Michael Slass <mikesl@wrq.com>.

;; Changes from 0.9a to 0.9b:

;; * Remove extra parenthesis.  Duh.

;; Changes from 0.9 to 0.9a:

;; * Fix bug making `browse-kill-ring-quit-action' uncustomizable.
;;   Patch from Henrik Enberg <henrik@enberg.org>.
;; * Add `url-link' and `group' attributes to main Customization
;;   group.

;; Changes from 0.8 to 0.9:

;; * Add new function `browse-kill-ring-insert-and-quit', bound to 'i'
;;   by default (idea from Yasutaka Shindoh).
;; * Make default `browse-kill-ring-quit-action' be
;;   `bury-and-delete-window', which handles the case of a single window
;;   more nicely.
;; * Note change of home page and author address.

;; Changes from 0.7 to 0.8:

;; * Fix silly bug in `browse-kill-ring-edit' which made it impossible
;;   to edit entries.
;; * New variable `browse-kill-ring-quit-action'.
;; * `browse-kill-ring-restore' renamed to `browse-kill-ring-quit'.
;; * Describe the keymaps in mode documentation.  Patch from
;;   Marko Slyz <mslyz@eecs.umich.edu>.
;; * Fix advice documentation for `browse-kill-ring-no-duplicates'.

;; Changes from 0.6 to 0.7:

;; * New functions `browse-kill-ring-search-forward' and
;;   `browse-kill-ring-search-backward', bound to "s" and "r" by
;;   default, respectively.
;; * New function `browse-kill-ring-edit' bound to "e" by default, and
;;   a associated new major mode.
;; * New function `browse-kill-ring-occur', bound to "l" by default.

;; Changes from 0.5 to 0.6:

;; * Fix bug in `browse-kill-ring-forward' which sometimes would cause
;;   a message "Wrong type argument: overlayp, nil" to appear.
;; * New function `browse-kill-ring-update'.
;; * New variable `browse-kill-ring-highlight-current-entry'.
;; * New variable `browse-kill-ring-display-duplicates'.
;; * New optional advice `browse-kill-ring-no-kill-new-duplicates',
;;   and associated variable `browse-kill-ring-no-duplicates'.  Code
;;   from Klaus Berndl <Klaus.Berndl@sdm.de>.
;; * Bind "?" to `describe-mode'.  Patch from Dave Pearson
;;   <dave@davep.org>.
;; * Fix typo in `browse-kill-ring-display-style' defcustom form.
;;   Thanks "Kahlil (Kal) HODGSON" <kahlil@discus.anu.edu.au>.

;; Changes from 0.4 to 0.5:

;; * New function `browse-kill-ring-delete', bound to "d" by default.
;; * New function `browse-kill-ring-undo', bound to "U" by default.
;; * New variable `browse-kill-ring-maximum-display-length'.
;; * New variable `browse-kill-ring-use-fontification'.
;; * New variable `browse-kill-ring-hook', called after the
;;   "*Kill Ring*" buffer is created.

;; Changes from 0.3 to 0.4:

;; * New functions `browse-kill-ring-forward' and
;;   `browse-kill-ring-previous', bound to "n" and "p" by default,
;;   respectively.
;; * Change the default `browse-kill-ring-display-style' to
;;   `separated'.
;; * Removed `browse-kill-ring-original-window-config'; Now
;;   `browse-kill-ring-restore' just buries the "*Kill Ring*" buffer
;;   and deletes its window, which is simpler and more intuitive.
;; * New variable `browse-kill-ring-separator-face'.

;;; Bugs:

;; * Sometimes, in Emacs 21, the cursor will jump to the end of an
;;   entry when moving backwards using `browse-kill-ring-previous'.
;;   This doesn't seem to occur in Emacs 20 or XEmacs.

Why? At byte-compile time not all variables or functions can be known  
by the byte-compiler, particularly when they are defined in other  
ELisp files. So a warning is emitted when something is felt missing.  
Unless the ELisp code fails in real life, i.e. when working with it,  
you don't need to care much about them.

Understand that warnings aren't errors and can leave them alone, I'd
like to get rid of the warnings to learn to write a program better.

I'd appreciate people to suggest ideas on how to get rid of them.
