Subject: [PATCH] Add HAVE_*_H checks around inclusions of netinet/in.h and
 sys/socket.h

Only include <netinet/in.h> and <sys/socket.h> if the system supplies them.
This is necessary to try and get the mingw32 build working again.

No need to include <sys/types.h> and <netinet/in.h> from cdns.c - these are
already included by <irc.h>.
