FLTK native in 'D'. Would that be useful?

Thanks. This should be fixed now.

I can't get used to the fact that in "D", you can't compare pointers if 
one of them may be null:

class Fl_Window {
   ...
};
Fl_Window first_window, this_window;
if (first_window==this_window) ...

Now if first_window is null, I get a crash that I would not get in C++. 
Ah well ;-)
