Description:
------------
Since curl 7.21.3 curl_easy_setopt has an option CURLOPT_RESOLVE [0]. Using this option from within PHP results in the following NOTICE and WARNING. Usage of this functionality is necessary for proper Sever Name Indication for verifying CA Certs in certain scenarios. The actual functionality presented by this option seems to work despite the notice and warning. 

The notice is: 

PHP Notice:  Use of undefined constant CURLOPT_RESOLVE - assumed 'CURLOPT_RESOLVE' in /var/www/localhost/htdocs/status-srv/sks_get_peer_data.php on line 351

This Notice can be removed by explicitly setting a string rather than using it as a constant, however, the following Warning is still presented in both scenarios: 

Warning: curl_setopt() expects parameter 2 to be long, string given in /var/www/localhost/htdocs/status-srv/sks_get_peer_data.php on line 351

[0] http://curl.haxx.se/libcurl/c/curl_easy_setopt.html

Test script:
---------------
<?php
// Minimum working example to produce the reported behavior
$ch = curl_init("https://www.google.com:80/");
curl_setopt($ch, CURLOPT_RESOLVE, "google.com:80:173.194.32.5");
curl_exec($ch);
?>

Expected result:
----------------
No warning

Actual result:
--------------
works, but with notice and warning output.
