Yes, it turned out that a change in `rfc2047.el' caused it, see
http://article.gmane.org/gmane.emacs.gnus.general/62033.

Yes.

Does this XEmacs have MULE?  Maybe we should add something to the
User-Agent in `gnus-extended-version' if (featurep 'mule) is nil.

Here's another example:

Double encoding is necessary, e.g. if the user types the following
Subject:

| Subject: Ich hab' da mal 'ne Fräge: Was bedeuten denn diese Zeichen =?ISO-8859-15?Q?=F6?= ?

Did you try with a no-MULE XEmacs?  Could there be a difference
between an XEmacs without MULE on Windows and GNU/Linux?

This has been fixed in Gnus CVS.  It should also be fixed in
xemacs-pkg-1_90.

BTW, will anyone sync the XEmacs Gnus package to Gnus 5.10.8 (released
today)?  Is the Position still Vacant?  See
<http://article.gmane.org/gmane.emacs.xemacs.beta/22341>.
