[Bug libc/11070] Glibc netdb.h does not provide prototype for 'iruserok'

["simon at josefsson dot org" <sourceware-bugzilla at sourceware dot org>]

------- Additional Comments From simon at josefsson dot org  2009-12-09 17:28 -------
If you want to take the opportunity to also export the iruserok_af interface,
which seems equally exported by libc.so but not prototyped in any header file,
here is an alternative patch.   The iruserok_af interface appears to be a more
usable interface (because it is not IPv4 specific).
