  Changelog for the c-ares project

* September 29

- Henrik Stoerner fix: got a report that Tru64 Unix (the unix from Digital

  when they made Alpha's) uses /etc/svc.conf for the purpose fixed below for

  other OSes. He made c-ares check for and understand it if present.

- Now c-ares will use local host name lookup _before_ DNS resolving by default

  if nothing else is told.

- Henrik Stoerner: found out that C-ARES does not look at the /etc/host.conf

- Henrik Stoerner: found out that c-ares does not look at the /etc/host.conf

  file to determine the sequence in which to search /etc/hosts and DNS.  So on

  systems where this order is defined by /etc/host.conf instead of a "lookup"

  entry in /etc/resolv.conf, C-ARES will always default to looking in DNS

  entry in /etc/resolv.conf, c-ares will always default to looking in DNS

  first, and /etc/hosts second.

  c-ares now looks at
