Related with the threadsafe capability of getaddrinfo:
- Constantine Sapuntzakis reported that Darwin 6.0 a.k.a. MAC OS X 10.2 and newer have a threadsafe getaddrinfo. - Fix Dragonfly BSD triplet detection. - In case the hard-coded knowledge says that getaddrinfo is threadsafe, an additional check is done to verify that h_errno is also defined. If h_errno isn't defined, we finally assume that it isn't threadsafe. Jamie Lokier provided the inspiration for this extra check.
