…richton When getaddrinfo returns EAI_SYSTEM retrieve actual error from errno. Fixes issue rust-lang#36546. This change also updates libc to earliest version that includes EAI_SYSTEM constant. Previously, in cases where `EAI_SYSTEM` has been returned from getaddrinfo, the resulting `io::Error` would be broadly described as "System error": Error { repr: Custom(Custom { kind: Other, error: StringError("failed to lookup address information: System error") }) } After change a more detailed error is crated based on particular value of errno, for example: Error { repr: Os { code: 64, message: "Machine is not on the network" } } The only downside is that the prefix "failed to lookup address information" is no longer included in the error message.
