/** Windows 10 supports AF_UNIX as of build 17603, with
    support provided in the header file <afunix.h>.  However,
    only the latest Windows SDK provides this file; older SDKs and
    MinGW do not.

    Hence we define SOCKADDR_UN here.  We do not expect this definition to change
    as Windows has some pretty good binary backwards-compatibility guarantees.

    This shouldn't pose a problem for older versions of Windows; we expect them to
    fail with an error whenever we try to make a socket of type AF_UNIX. */
