Are you saying that I should drop this?
-    return LISTVIEW_SetIconSpacing(infoPtr, (short)LOWORD(lParam),
(short)HIWORD(lParam));
+    if(lParam == -1)
+      return LISTVIEW_SetIconSpacing(infoPtr, -1, -1);
+    return LISTVIEW_SetIconSpacing(infoPtr, LOWORD(lParam), HIWORD(lParam));
This would net us 2 more todo_wine tests.

Also, what's up with the daily test runs? Will they be fixed any time soon?
