Hello folks,

adjusting some fields...

Obviously still present in Wine 1.7.10

Source:
http://source.winehq.org/git/wine.git/blob/2a3932a0a22f5f5fb8a90d718e00ae7357c6a990:/dlls/ntdll/ntdll.spec#l50

--- snip ---
 50 @ stub KiUserExceptionDispatcher
--- snip ---

--- quote ---
Let them know that the KiUserExceptionDispatcher function is not called in Wine
when exceptions happen, which it is on Windows."
--- quote ---

Most likely they want a hook as early as possible in usermode exception
handling.
So just providing a stub is not enough.

Maybe small wrapper around raise_exception() or just call
KiUserExceptionDispatcher() at raise_exception() entry to simulate it.

Regards
