That is almost enough. The last trick is that you have to add paths to
generated files to header search directory. That is done by
subvariant.implciit-includes rule (in virtual-target.jam), and if you look at
the compile-action class in builtin.jam you'll see this:

local s = [ $(self.targets[1]).creating-subvariant ] ;
return [ $(property-set).add-raw
[ $(s).implicit-includes "include" : H ] ] ;

That's where the extra <include> comes from. And without extra includes, V2
just won't find files included from .rc file.

Ok. Looking forward to that patch.
