Summary: Name resolution does not work in 6.3.4

Details: I have just compiled fetchmail-6.3.4, to replace an existing 6.2.5.  New fetchmail fails to resolve IP address of the IMAP server I am polling.  Replacing server name with IP address in ~/.fetchmailrc restores functionality.  So does defining the name in /etc/hosts.
Full log from `fetchmail -v -v' is:
-----------------------
fetchmail: 6.3.4 querying mail.ual.com. (protocol IMAP) at Fri Apr 21 17:53:59 2006: poll completed
fetchmail: Query status=2 (SOCKET)
fetchmail: Deleting fetchids file.
fetchmail: normal termination, status 2
fetchmail: Deleting fetchids file.
-----------------------

I also have the output of strace command (strace -o debug.out ./fetchmail -v) which I can send.

Just to prove the point, I tried to compile fetchmail-2.5.5, and it does not have this problem.  I could not find any versions in between.
