This patch increases the maximum host name length for 'dnsd' to 40 characters in length and fixes a resolving bug. For example, if there are two entries in the 'dnsd.conf' file of 'foo1' and 'foo2'. Doing a 'nslookup foo2' the 'dnsd' will always return the IP address of 'foo1' because the string comparison is faulty.
