Re: Fixes for nnrss.el (and rfc2047.el) in the v5-10 branch

[Katsumi Yamaoka <yamaoka@jpl.org>]

I've committed the changes in both the Gnus trunk and the v5-10
branch.  The changes in the v5-10 branch are for only Gnus v5.11,
so please don't merge them back into the Gnus trunk.

I solved it by using windows-1252 if it is available, or making
a text/plain article instead of a MIME article for old Emacsen
which sometimes caused an error.

FYI: you can use the windows-1252 coding system even in Emacs 21
by using ARISAWA Akihiro's codepage-ex.el, which is available at:

http://www.nijino.com/ari/emacs/codepage-ex.html

I've put the following in my ~/.emacs file.

(if (and (not (featurep 'xemacs))
	 (= emacs-major-version 21)
	 (not (require 'code-pages nil t)))
    (progn
      (require 'codepage-ex)
      (mapc (lambda (cp) (codepage-ex-setup (car cp)))
	    (cp-ex-supported-codepages))
      (define-coding-system-alias 'windows-1250 'cp1250)
      (define-coding-system-alias 'windows-1251 'cp1251)
      (define-coding-system-alias 'windows-1252 'cp1252)
      (define-coding-system-alias 'windows-1253 'cp1253)
      (define-coding-system-alias 'windows-1254 'cp1254)
      (define-coding-system-alias 'windows-1255 'cp1255)
      (define-coding-system-alias 'windows-1257 'cp1257)))

Done.
