[Ecls-list] winsock.h or winsock2.h

[Anton Vodonosov]

It turned out that the <windows.h> file includes winsock.h
which caused the conflict with winsock2.h.

There is a special macro, WIN32_LEAN_AND_MEAN, that prevents
inclusion of redundant headers in windows.h.

After I've added #define WIN32_LEAN_AND_MEAN 1 at the
top of ecl/config.h, usocket was compiled successfully.

Best regards,
