This is the warning:
Warning: `default-mode-line-format' is an obsolete variable
(as of Emacs 23.2); use `mode-line-format' instead.
That is incorrect and useless. Clearly, you cannot use
`mode-line-format' in place of `default-mode-line-format'.
The warning should instead say something like this, based on the doc
string:
Warning: `default-mode-line-format' is an obsolete variable
(as of Emacs 23.2); use `(default-value 'mode-line-format)' instead.

Why `default-value', but not `setq-default'?

Should be obvious: Because the intention of a given occurrence
of `default-mode-line-format' might not be to set the default
value of `mode-line-format'.
Consider code that used, for example:
(setq mode-line-format default-mode-line-format)
A reasonable update of that code would likely be
(setq mode-line-format (default-value 'mode-line-format))
That does not set the default value of `mode-line-format'.

Now fixed.
