commit 7c9caecfebf7d15899fe361324c414fbfc7b1317

    Fix the networking stuff on (current) OS X
    
    OS X's headers split up the current and old (BIND 4) nameserver stuff
    slightly differently than Linux does, but explicitly including
    arpa/nameser_compat.h does the right thing on both. Part of #580301
