Hi Scott,
I didn't see a reply to your AcceptEx patches yet, sorry if I missed it and you get this again. Please submit one patch per email only.
I admittedly don't know much about the wineserver stuff, but I've noticed a couple of style issues in the winsock code:
The indentation common in socket.c is either a two-space indent or a four-space indent. Please don't add new code with an eight-space indent.
Also, the common convention for ifs is if (cond) { and not if(cond){
Apart from those minor nitpicks, the code looks good.
Cheers, Kai
