Proposed fix by BitSpirit team seams to be more accurate (as fixing the problem for both IPv4 and IPv6 versions). Please update your patch, if you can.
Also, I should say that you were right and I made a mistake. I built ws2_32 with make ws2_32.dll, but I copied *.fake file naively thinking it is changed something. Well, now I've rebuilt it according to BitSpirit's proposition, copied ws2_32.dll.so to /usr/lib32/wine, replacing the old one, and it works perfectly!
Thank you very much for your assistance! :)
