How is that relevant to what the Founders considered a Natural Born Citizen? Congress does not have the power to define or re-define terms used in the Constitution. If they did, then they could re-define "arms" to be "pea-shooters" and the Second Amendment would be dead.
The obvious intent of the Founders was to eliminate one very great threat that a President would have divided loyalties or even the appearance of divided loyalties.
Who can deny that Obama has the appearance of divided loyalties?
After-birthers are intellectual cabbages.
They all want the constitution relegated to the septic tank.
