make_envelope was in a late stage renamed to return_envelope, because it 
was not really conform the behaviour expected from a helper function 
starting with "make" (e.g. make_tuple, make_pair)

So if you replace make with return, it will compile again (the Box2D 
error will vanish as well).

Sorry for the inconvience.
