  Ok, ok...

  Here's how I'd solve it:

	1. comment out the int* parameters in the defs;
	2. compile; it's going to fail, of course;
	3. go to the generated C file, look for the wrapper, copy it
	4. go to the .override file, add something like
%% override wnck_window_get_geometry noargs
<paste the wrapper here>
	5. Edit the wrapper
	  a) declare a few int variables, pass the missing arguments by taking
a reference to the variables, like &x, &y, &width, &height
	  b) replace the Py_None return block with
		return Py_BuildValue("iiii", x, y, width, height);
	6. Uncomment back the parameters in the .defs
	7. Compile, test, submit the patch

  Good luck :-)
