I tried this in gtkutil.c

+          x_clear_area (FRAME_X_DISPLAY (f), FRAME_X_WINDOW (f),
+                        oldx, oldy, oldw, oldh);
-          x_clear_area (f, oldx, oldy, oldw, oldh);

and it didn't compile (wrong number of arguments)...

I don't understand this:

remember that

   79bbe53a991007036ce9bcf897a4ce1371f516ea  2015-05-23 09:21:27 (GMT)

works as expected, while

  ee14727ce033bae3bc11af35e7843604e5a5e635   2015-05-23 10:27:56 (GMT)

shows the issue, and ee14727ce033bae3bc1... has already xfns.c with that 
above (+) code..
