EAI_NODATA is obsolete; current implementations just return EAI_NONAME in
that case.  Note that EAI_NODATA is not listed as a valid return code in
RFC 3493.

This should be fixed in the krb5 source, but in the meantime the
workaround would be to compile with -DEAI_NODATA=EAI_NONAME, which the
code appears to deal with correctly.
