    Older versions of glibc requires extra feature macros
    for function open_memstream.
    
           fmemopen(), open_memstream(), open_wmemstream():
               Since glibc 2.10:
                   _XOPEN_SOURCE >= 700 || _POSIX_C_SOURCE >= 200809L
               Before glibc 2.10:
                   _GNU_SOURCE
    
    src/sbus/sssd_dbus_introspect.c: In function 'introspect_begin':
    src/sbus/sssd_dbus_introspect.c:82: error: implicit declaration of function 'open_memstream'
    src/sbus/sssd_dbus_introspect.c:82: warning: assignment makes pointer from integer without a cast
