 |  Sendmail is not threaded, hence it is perfectly fine to use __res. I

 |    - allows for linking against threaded libraries
 
 Yes, someone else encountered the same problem and tried to fix it.

 As long as it is not actually using threads and _res gets resolved to the
 libc one instead of the libpthread one it should be ok. In the long term
 it is better to use the new resolver functions though.
