Ah, sorry, I didn't even see that comment. I don't even agree that WINE 
gets things wrong on a regular basis, at least not in this context. Your 
structure is "wrong" in a way that doesn't influence external behaviour 
at all. I guess the nice way of saying it would've been "Wow, what a 
surprise, WINE doesn't need to clone internal structures!" which, 
although sarcastic, is a lot more factual and is more a pun towards 
ReactOS ;)

We usually send patches, although it's true that kernel32/ntdll sharing 
has been very hard due to the large architectural differences. Mike and 
other developers (afaik) are working on making this more NT/ROS-like, 
and I can't wait until we can share more code. From what I've seen in 
WINE and the WINETEST failures we're getting, our kernel32/ntdll 
user-mode code is a lot worse then WINEs... our original sync was what, 
5 years ago? ;)

Nice, Steven never told me about this...thanks a lot!

Actually, Steven has been doing work on forwarding me the bugs, and I've 
been fixing them ;) I'm handling this on a case-by-case basis, but we 
are currently working on a system called SIN, which is a Continous 
Integration System. Casper is leading the project, but it allows us to 
automatically compile builds to ensure that the latest commit doesn't 
break it (in which case it will be automatically removed). A large 
number of us (especially Steven and I) want to make SIN also actually 
boot the image in an emulator, and then run automated winetests. This is 
currently being disputed, since we cannot possibly do this for every 
build, it would slow down the process too much. One of the suggestions 
was to do this only X builds, but I'm not sure if that comprise has been 
approved yet. Defintely, I think you don't have this problem in WINE, 
since you can easily execute WINE in the compiler environment without 
requiring booting from an image in an emulator. But we're working on it! 
We've even thrown the idea of User-Mode ReactOS on the table.
