Comment (by ballapete):

 After removing `os/availability.h` `GCC 4.2` reports:

 `src/lib/thirdparty/apple/dnsinfo.h` has the prototype – guarded by
 statements I do not know how to interpret:

 {{{
 __BEGIN_DECLS

 /*
  * DNS configuration access APIs
  */
 const char *
 dns_configuration_notify_key    (void)
 API_AVAILABLE(macos(10.4), ios(2.0));

 dns_config_t *
 dns_configuration_copy          (void)
 API_AVAILABLE(macos(10.4), ios(2.0));

 void
 dns_configuration_free          (dns_config_t   *config)
 API_AVAILABLE(macos(10.4), ios(2.0));

 void
 _dns_configuration_ack          (dns_config_t   *config,
                                  const char     *bundle_id)
 API_AVAILABLE(macos(10.8), ios(6.0));

 __END_DECLS
 }}}

 Maybe `GCC7` is an appropriate `compiler`?
