test application

This problem is caused by changing the code of WM_NOTIFY.

In other words, this application acts as follows:
1. Wine (and Windows)'s listview control sends WM_NOTIFY message to
ExplzhWClass window to get item info with LVN_GETDISPINFOA code.
2. Then its window procedure fills LV_DISPINFO structure, and changes the code
to LVN_GETDISPINFOW.
3. Even so, Windows can display correctly on NT systems. But Wine doesn't.

I didn't find any documents of this behavior. Wine should follow this behavior
or not?

I create a small test application of this behavior, and attach it.
Thank you.
