bug#36022: 26.2.50; errors byte-compiling gnus.el

[Sven Joachim]

Byte-compiling lisp/gnus/gnus.el is broken on emacs-26, this is what
happens here after removing the corresponding gnus.elc file:

,----
| make[1]: Verzeichnis „/usr/local/src/emacs/lisp“ wird betreten
| EMACSLOADPATH= '../src/emacs' -batch --no-site-file --no-site-lisp --eval 
'(setq load-prefer-newer t)'  -f batch-byte-compile gnus/gnus.el
| 
| In gnus-interactive:
| gnus/gnus.el:3335:15:Error: Forgot to expand macro gnus-data-header in 
(gnus-data-header (gnus-data-find (gnus-summary-article-number)))
| gnus/gnus.el:3337:11:Error: Forgot to expand macro gnus-data-find in 
(gnus-data-find (gnus-summary-article-number))
| gnus/gnus.el:3337:29:Error: Forgot to expand macro 
gnus-summary-article-number in (gnus-summary-article-number)
| make[1]: *** [Makefile:297: gnus/gnus.elc] Fehler 1
`----

The same error occurs on a fresh bootstrap, however I can successfully
byte-compile gnus.elc with a snapshot from May 12, so something has
broken in the meantime on emacs-26.
