Curious Josh if your typescript definition compiler can replace externc? How much overlap is there?
I wanted to do exactly what you did with typescipt and use it's compiler but I didn't have enough time so I went the gcc extern route, there was a couple massive discussions a year ago bout that and using typescript definition files.
