summary for the remaining byte compiler warnings


From: Dan Nicolaescu
Subject: summary for the remaining byte compiler warnings
Date: Thu, 08 Nov 2007 22:57:02 -0800

Below is the list of byte compiler warnings when bootstrapping
(excluding about 200 unknown function warnings which are hard to fix
without fixing a few bugs in the byte compiler and adding some
features) together with some brief analysis. 
Please help fix these issues.

A patch was posted some time ago for this one:

In toplevel form:
cc-vars.el:158:1: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.


No idea about this one:

In toplevel form:
pgg-parse.el:183:8:Warning: reference to free variable `pgg-parse-crc24'



These probably need fixing:

In toplevel form:
simple.el:2564:2:Warning: `make-variable-frame-local' is an obsolete function
    (as of Emacs 22.2); use a frame-parameter instead
simple.el:2592:2:Warning: `make-variable-frame-local' is an obsolete function
    (as of Emacs 22.2); use a frame-parameter instead


What's the best way to silence this one?

In tex-mode:
tex-mode.el:910:8:Warning: function `tex-mode' defined multiple times in this
    file


No idea here:

In toplevel form:
cc-subword.el:147:5:Warning: `make-variable-buffer-local' should be called at
    toplevel


Not sure what to do about this:

In cperl-mode:
cperl-mode.el:1793:9:Warning: `vc-header-alist' is an obsolete variable; use
    `vc-BACKEND-header' instead.
cperl-mode.el:1805:25:Warning: reference to free variable
    `compilation-error-regexp-alist'
cperl-mode.el:1806:19:Warning: assignment to free variable
    `compilation-error-regexp-alist'


How about this?

In toplevel form:
python.el:2067:1:Warning: reference to free variable
    `python-mode-abbrev-table'


These probably need fixing:

In toplevel form:
viper-init.el:433:6:Warning: `make-variable-frame-local' is an obsolete
    function (as of Emacs 22.2); use a frame-parameter instead
viper-init.el:440:6:Warning: `make-variable-frame-local' is an obsolete
    function (as of Emacs 22.2); use a frame-parameter instead
viper-init.el:450:6:Warning: `make-variable-frame-local' is an obsolete
    function (as of Emacs 22.2); use a frame-parameter instead
viper-init.el:455:6:Warning: `make-variable-frame-local' is an obsolete
    function (as of Emacs 22.2); use a frame-parameter instead


This looks like it might be a bug in the code:

In reftex-make-separate-toc-frame:
reftex-toc.el:998:35:Warning: `focus-frame' is an obsolete function (as of
    Emacs 22.1); it does nothing.


These are all for gnus:

In gnus-batch-score:
gnus-kill.el:690:11:Warning: `nnmail-spool-file' is an obsolete variable; This
    option is obsolete in Gnus 5.9.  Use `mail-sources' instead.

In nnkiboze-generate-groups:
nnkiboze.el:201:10:Warning: `nnmail-spool-file' is an obsolete variable; This
    option is obsolete in Gnus 5.9.  Use `mail-sources' instead.

In gnus-jog-cache:
gnus-cache.el:623:10:Warning: `nnmail-spool-file' is an obsolete variable;
    This option is obsolete in Gnus 5.9.  Use `mail-sources' instead.

In gnus-display-x-face-in-from:
