Re: ncat should try connecting to all resolved addresses, not only the first one

I made a patch which adds this functionality: if one resolved address fails, next one is tried.
You can find it there: https://bugzilla.redhat.com/show_bug.cgi?id=978964#c6

I am not very familiar with the code, so I'd like to consult how to do this better. I don't think the way I made it is 
ideal and would like to make it more acceptable.
Thanks a lot for your feedback!

Subject: ncat should try connecting to all resolved addresses, not only the first one

This problem was already reported in Red Hat Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=978964
As I described in my comment, ncat should try connecting to another address resolved by getaddrinfo(), if connecting to 
one fails.
In current situation, I cannot connect to a host whose hostname is resolved to more addresses, the first one resolved 
address is IPv6 and I cannot connect through IPv6.
I'm going to make a patch which would do this.
If you have anything to tell me or suggest about this, tell me. I will start making a patch and if I succeed, I'll post 
it here.
