+**  WS2TCPIP.H - WinSock2 Extension for TCP/IP protocols
+**
+**  This file contains TCP/IP specific information for use
+**  by WinSock2 compatible applications.
+**
+**  To provide the backward compatibility, all the TCP/IP
+**  specific definitions that were included in the WINSOCK.H
+**  file are now included in WINSOCK2.H file. WS2TCPIP.H
+**  file includes only the definitions  introduced in the
+**  WinSock 2 Protocol-Specific Annex document.
