Summary:                    [patch] Each time a device sends a REGISTER, the
error "No address associated with nodename" appears
Description: 
The following messages appear continuously:

sip_uri_domain_cmp sip.covert.org - sip.covert.org
[Dec 28 10:59:23] ERROR[13395]: netsock2.c:205 ast_sockaddr_parse:
getaddrinfo("sip.covert.org", "(null)", ...): No address associated with
nodename
[Dec 28 10:59:23] ERROR[13395]: netsock2.c:205 ast_sockaddr_parse:
getaddrinfo("sip.covert.org", "(null)", ...): No address associated with
nodename

This is because "If the AI_NUMERICHOST bit is set in the ai_flags member
of the hints structure, then a non-NULL nodename string must be a numeric
host address string. Otherwise an error of EAI_NONAME is returned. This
flag prevents any type of name resolution service (e.g., the DNS) from
being called."

See http://www.manpages.info/macosx/getaddrinfo.3.html

Patch supplied to eliminate the message on Darwin.

You mean that on Darwin, it returns EAI_NODATA instead of EAI_NONAME when a
non-numeric host is passed, right?

EAI_NODATA
No address associated with nodename.
EAI_NONAME
nodename nor servname provided, or not known.

Whereas on e.g. Linux it returns EAI_NONAME. (If _GNU_SOURCE is defined,
there is a EAI_NODATA, but it is not returned for the AI_NUMERICHOST
reason.)

You'll probably want to change that to:

if (
#ifdef darwin
 e != EAI_NODATA
#else
 e != EAI_NONAME
#endif 
) {

or something..
