Ok, I added

	import core.sys.windows.winuser;
	__gshared extern(C) core.sys.windows.winuser.HANDLE 
function(GdkWindow*) gdk_win32_window_get_handle;
	Linker.link(gdk_win32_window_get_handle, 
"gdk_win32_window_get_handle", LIBRARY_GDK);

to GtkD\generated\gtkd\gdk\c\functions.d

and rebuilt and it seems to work. Hopefully that is the right 
place so in the future when I replace GtkD with it won't show up 
as a bug in my code somewhere. I assume master will be updated 
with this at some point?
