Okay, you can do it with the hack below, but you have to do the putenv
hack *before* you call SDL_Init.

Also from what I understood about SDL you can only have one window per
process, at least only one window embedded in a GTK window as the putenv
hack is global. 

I dunno if it's possible with threads to get more than one SDL window into
a GTK one, but it's possibly the ugliest hack I've seen yet. Plus when you
start trying to do this stuff with bonobo controls, then you have fun
about waiting for windows to be realised before calling sdlinit.
