For me, in Emacs 22, by default RCtrl-AltGR is equivalent to Ctrl-Meta 
provided I press the RCtrl key first and hold it, then press AltGr, which is 
the other way around to what you wrote above!  If I press and hold AltGr and 
then press RCtrl, the RCtrl makes no difference.

If I set w32-recognize-altgr to nil then AltGR alone is equivalent to 
Ctrl-Meta and RCtrl has no effect, regardless of precisely when I press it.

Yes.  However, I think it might be useful to document in the Emacs manual 
the way that RCtrl affects AltGr, which seems to be specific to Emacs and is 
not something that I would have expected.
