IPv4 connection patch different in downstream

[robert-scheck]

The downstream patch by Lubomir Kundrak ([email protected]) at http://pkgs.fedoraproject.org/cgit/jwhois.git/tree/jwhois-4.0-connect.patch to fix IPv4 connections is a bit different compared to the upstream implementation.

Could somebody being knowledged enough in C review these differences and decide if these are needed at upstream as well or if the current upstream code is fine, please?
