It will be possible to add a compat definition that replaces
`with-no-warnings' with `progn' when compiling to dgnushack.el
or whatever.  However, it disables people, who use XEmacs or
Emacs 21 to develop Gnus, from loading .el files.  So, it is
better to add it to every file which uses `with-no-warnings'.
Is it ok?

In that case, the definition should be made available only when
compiling (or when loading .el files) because `with-no-warnings'
should never be bound normally in XEmacs and Emacs 21.

  (unless (fboundp 'with-no-warnings)
    (defmacro with-no-warnings (&rest body)
      `(progn ,@body))))

Yes, that is for *only* suppressing warnings, in place of
`with-no-warnings'.  Using neither the complicated things nor
`with-no-warnings' makes it simple, if we don't mind warnings
when bootstrapping Emacs.
