EAI_NODATA deprecated, not always defined
Brian Kantor reports (on the kerberos@mit list today) that krb5-1.6
doesn't build on FreeBSD 6.1 because they've done away with
EAI_NODATA, which was removed from the getaddrinfo API in RFC 3943.
This patch conditionalizes two tests for EAI_NODATA on the macro being
defined, and also adds handling for EAI_OVERFLOW, a new error code
added in RFC 3943.
