Description:
------------
ext/standard/dns.c won't comiple on Solaris 10 which does not have IPv6 support installed. The problem is in the for loop in  function _php_dns_free_res at line 369. Specifically resolv.h has __res_state_ext define as

struct __res_state_ext;

Which causes "structure has no member" error. Workaround is to comment out the for loop in _php_dns_free_res.

Sorry I don't have a spare machine to install Solaris 10 with IPv6 on and report the results. 

Actual result:
--------------
/usr/local/src/php5-200510241430/ext/standard/dns.c: In function `_php_dns_free_
res':
