K 10 svn:author V 3 pfg K 8 svn:date V 27 2019-01-28T02:26:05.572101Z K 7 svn:log V 568 MFC r342379, r342383: gai_strerror() - Update string error messages according to RFC 3493. Error messages in gai_strerror(3) vary largely among OSs. For new software we largely replaced the obsoleted EAI_NONAME and with EAI_NODATA but we never updated the corresponding message to better match the intended use. We also have references to ai_flags and ai_family which are not very descriptive for non-developer end users. Bring new error messages based on informational RFC 3493, which has obsoleted RFC 2553, and make them consistent among the header and manpage. END
