- *
- * On Windows NT, if we define _WIN32_WINNT to be 0x0400 (in order
- * to use Service Pack 3 extensions), windows.h includes winsock2.h
- * (instead of winsock.h), which doesn't define many socket options
- * defined in winsock.h.
- *
- * We need the socket options defined in winsock.h.  So this file
- * includes winsock.h, with _WIN32_WINNT undefined.
