NAME
       CURLOPT_SOCKS5_GSSAPI_NEC - set socks proxy gssapi negotiation
       protection

SYNOPSIS
       #include <curl/curl.h>

       CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SOCKS5_GSSAPI_NEC, long
       nec);

DESCRIPTION
       Pass a long set to 1 to enable or 0 to disable. As part of the gssapi
       negotiation a protection mode is negotiated. The RFC1961 says in
       section 4.3/4.4 it should be protected, but the NEC reference
       implementation does not.  If enabled, this option allows the
       unprotected exchange of the protection mode negotiation.

DEFAULT
       ?

         curl_easy_setopt(curl, CURLOPT_SOCKS5_GSSAPI_NEC, 1L);
         ret = curl_easy_perform(curl);
