   4 /* AI_NUMERICSERV as a value for the `ai_flags' member
   5  * of `struct addrinfo' of header <netdb.h> has only
   6  * been available since:
   7  *
   8  *   POSIX 1003.1-2008, Issue 7
   9  *   glibc 2.3.4
  10  *   Mac OS X 10.6
  11  *   etc.
  12  *
  13  * Fortunately, its main purpose seems to be only
  14  * to optimize calls of `getaddrinfo', and because it
  15  * is meant to be a bit flag, it can therefore be
  16  * [relatively] safely ignored by defining it to have
  17  * the value zero.
