This is a common problem for packages that use res_query in libresolv. 
On x64_64 and possibly other architectures, res_query is defined as a 
macro in <resolv.h>, and unless you include that header file in 
configure test for res_query, the macro won't get picked up, the actual 
name of the function won't be used and hence the test will fail at link 
time.

Attached patch should fix it.
