I don't know what's happening in XEmacs 21.5, but I simply
groped how to make Gnus work correctly.  The reason I said it
is a syntax-table bug is because the copy-syntax-table function
doesn't copy modified syntax entries as I wrote a comment in
the dgnushack,el file:

  ;; The original `with-syntax-table' uses `copy-syntax-table' which
  ;; doesn't seem to copy modified syntax entries in XEmacs 21.5.

(let ((table (copy-syntax-table emacs-lisp-mode-syntax-table)))
  (modify-syntax-entry ?= " " table)
  (with-temp-buffer
    (with-syntax-table table
      (insert "foo=bar")
      (goto-char (point-min))
      (forward-sexp 1)
      (buffer-substring (point) (point-max)))))
 => ""

And I've redefined the with-syntax-table macro there so that it
doesn't use copy-syntax-table when building Gnus.  Since it is
no more than a makeshift, I am willing to remove it if there is
a better way.
