This library doesn't try to use Windows's socket implementation:
header winsock.h and library wsock32 or header winsock2.h and library
ws2_32.

I've changed file "configure" to use winsock.h and wsock32, getting
the following error messages:

checking for socket in -lwsock32... yes
checking for inet_ntoa... no
checking for inet_ntoa in -lnsl... no
configure: error: cannot find library function inet_ntoa

Next problem is function inet_ntoa and so on. This library seems not
ported to Windows.
