lm-resolver.c: limit conditional include to OS X Explicitly including arpa/nameser_compat.h is only necessary for OS X. It's unneeded on other OSes. Some, e.g. Linux and NetBSD, include nameser_compat.h from nameser.h anyway, so at minimum, it's redundant. In the case of NetBSD, this was causing build breakages on some architectures due to legacy code in nameser_compat.h being exposed before the inclusion of nameser.h, which sets dependent macros. committer: mcabber <lm@freakysoft.de>
