Does "ping -6 myhost.org" work too?

Since you're using Visual Studio 2013, you must be using
Vista or Win-8? So if you have IPv6 enabled (default on Win-8),
maybe libcurl, cares etc. is trying to get the IPv6 address and
fails somehow. Try adding:
    curl_easy_setopt (curl,CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4);

if you don't care about IPv6. Does an dotted IPv4-address
in your URL work?.
