I would be happy with that... It still would mean that you'd have to
keep a separate tree, as you wont be able to add the multiproto core
changes into the master branch, with or without the #ifdef, until Manu
is done with it and it all gets reviewed.  You should check with Mauro
also, if he'll be friendly to this idea, as he would have to handle that
with his gentree.pl script to prevent that stuff from going upstream.
