axis2c sets deprecated win32 socket options that avoid subsequent opening of sockets

In util/src/network_handler.c - lines 239-240 the default behaviour of socket creation through windows API gets changed:

setsockopt(INVALID_SOCKET, SOL_SOCKET, SO_OPENTYPE, (char *)&sock_opt,
sizeof(sock_opt));

As you can find in the MSDN documentation for SOL_SOCKET Socket Options, one should not use this options:

This option avoids the subsequent opening of sockets by other APIs like Orbacus (Corba).

As we did comment out these two lines, everything worked correctly.
So we assumed that this code is obsolete.
