+if (!is_wine) /* FIXME: remove once Wine is fixed */
+    check_z_order(hwnd_A, 0, hwnd_B, 0, TRUE);

There is a todo_wine macro for this. You should first add the tests containing todo_wines
and add a following patch to fix the bug and remove the todo_wine.

There are also some styling issues with this patch. Please use a similar style of the surrounding code.

And is this for a specific application?

Thanks,
Zhiyi
