    Ensure that _GNU_SOURCE is defined for NI_MAXHOST and NI_MAXSERV
    
    Since glibc 2.8, these defines like `NI_MAXHOST` are exposed only
    if suitable feature test macros are defined, namely: _GNU_SOURCE,
    _DEFAULT_SOURCE (since glibc 2.19), or _BSD_SOURCE or _SVID_SOURCE
    (before glibc 2.19), see GETNAMEINFO(3).
