WM_CREATE failure and SetScrollRange argument validation

I've noticed another two things where Wine and Windows XP differ:

1. SetScrollRange(hWnd, SB_VERT, 0, -1) does nothing in WinXP, and is 
equivalent to SetScrollRange(hWnd, SB_VERT, 0, 0) in Wine. I guess it's 
true for all kinds of invalid arguments.

2. In WinXP, returning -1 from WM_CREATE causes window creation to fail 
- the newly created window is automatically destroyed (which sends 
WM_DESTROY to the window). In Wine, WM_DESTROY is not sent (which 
prevents the example program to finish).

The short piece of relevant code can be downloaded from:
