MIME files in MSWindows - Emacs 21.1.1

I'm running Emacs 21.1.1 under WinME and using it to read mail.  This
version of emacs does not interpret MIME-encoded mail when under
windows, but simply displays it as an ASCII message.  (When I first
try and read mail, the status line says "feature rmail-mime not
supported").

That's normally ok, but sometimes I actually want the byte-stream or
.gif (etc.) data.  Doing rmail-resend and reading the resent mail with
another mail reader (such as Netscape) used to work but it doesn't
anymore.  (I don't remember what caused that to first fail, probably
the upgrade to 21.1 from whatever I used before.)  I believe there's a
DOS utility that pulls apart MIME but I have no idea what it's called
or where to find it.

Does anyone know if either 1) I can get Windows based emacs to
interpret Mime or 2) there is a DOS-based utility around to pull apart
these messages (and eliminate the character-based line endings that
emacs inserted)?

Thank you in advance,
