psqlodbc - psqlodbc: At VC6, although there are winsock2.h and

Log Message:
-----------
At VC6, although there are winsock2.h and ws2tcpip.h, there is neither
a definition of the addrinfo structure nor a definition of getaddrinfo()
and a freeaddrinfo() function.
It seems that a header and a library are insufficient somehow.
