I have had bug reports containing that line above. I had to think very long
to find out what the problem was. These people wanted to play freeciv
on a single computer without having tcp/ip installed. Yes, that's
possible! Sometimes IPX/SPX is installed by default on windows but
not tcp/ip (e.g. on win95). 

I don't know a situation in which the socket call should fail when
tcp/ip is properly installed. And socket seems not to set errno...
So it is not easily possible to print meaningful error messages.

(You have to check h_errno, maintain your own table of messages
without using strerror) I don't think it is worth that.
