    Look at "cache.h": the first thing it does is to include
    "git-compat-util.h". And THAT in turn does include ALL the headers you
    added (string.h, netdb.h and unistd.h).

    So it would appear that for OS X, the

    #define _XOPEN_SOURCE_EXTENDED 1 /* AIX 5.3L needs this */
    #define _GNU_SOURCE
    #define _BSD_SOURCE

    sequence actually _disables_ those things.

    Some googling finds a python source diff:

    # On Mac OS X 10.4, defining _POSIX_C_SOURCE or _XOPEN_SOURCE
    # disables platform specific features beyond repair.
    - Darwin/8.*)
    + Darwin/8.*|Darwin/7.*)
    define_xopen_source=no
    ;;

    (and Ruby shows up as well in the google)

    Can you try to grovel around in the OS X headers, and see what the magic
    is to enable all the compatibility crud on OS X?
