As for url.el originated in W3, the code is too old to use with
Gnus for both 21.5 and 21.4.  I don't think `url-retrieve' that
gnus-compat.el redefines helps.  A workaround attached below is
the one I used to use, but I'm not sure if they are still useful
since I haven't been using XEmacs for a couple of years.  For
the same reason, and since I failed to have taken notes, I don't
recall other matters I faced.  But it is not hard to imagine
there are inconsistencies here and there, since most Gnus
developers are GNU Emacs users and they like to use Emacs' new
features (also it sometimes causes Gnus not to work for old GNU
Emacsen).

If it is the Gnus XEmacs package, I believe it's safe.  I have
no basis for it, though.

I'm no longer suitable for doing it, sorry.  The foremost reason
I got not to use XEmacs is that now I'm using Cygwin for almost
daytime (in the office).  On that platform, I was unable to build
XEmacs 21.5 that works normally.  It frequently crashes.
(Even so, I kept building it periodically keeping track of hg.
 However, it stopped months ago because it got unable to build
 on the latest Cygwin.)

That's good to here from the XEmacs team. :)  The only matter is
that there might be no Gnus developers who use 21.5.
