bug#3837: flyspell-mode in mail-mode doesn't work: message-signature-separator not defined

[Phil Smith]

flyspell-mode fails to work in mail-mode
See https://bugzilla.redhat.com/show_bug.cgi?id=505684
In Fedora 11, I get the error "Error in
post-command-hook: (void-variable message-signature-separator)"
This is with emacs-22.3-11.fc11.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. emacs junk.txt
2. M-x mail-mode
3. M-x flyspell-mode
4. type junk words
5. flyspell doesn't work

Actual results:
flyspell doesn't work

Expected results:
flyspell should work

Additional info:
flyspell works when not in mail-mode

If I put
    (defvar message-signature-separator "^-- *$" "\
    Regexp matching the signature separator.")
in .emacs, it works.
So it looks like message-signature-separator is not defined anywhere.
And a grep of the *.el supports this.
