I think this exposes what is arguably a bug in gnus.el, the
eval-when-compile around line 2378:

    ;; Define some autoload functions Gnus might use.
    (eval-and-compile

      ;; This little mapcar goes through the list below and marks the
      ;; symbols in question as autoloaded functions.

is autoloading gnus-data-header, gnus-data-find, and
gnus-summary-article-number as functions (i.e., the TYPE arg is nil),
even though they're actually macros.

But, we shouldn't start messing with that in the release branch, so here
is a patch which avoids triggering this error:
