76. The SOCKET type in Win64 is 64 bits large (and thus so is curl_socket_t on
that platform), and long is only 32 bits. It makes it impossible for
curl_easy_getinfo() to return a socket properly with the CURLINFO_LASTSOCKET
option as for all other operating systems.
75. NTLM authentication involving unicode user name or password only works
properly if built with UNICODE defined together with the WinSSL/schannel
backend. The original problem was mentioned in:

NOTE: this API is not really working on win64, since the SOCKET type on win64
is 64 bit large while its 'long' is only 32 bits.
NOTE: this API is deprecated since it is not working on win64 where the SOCKET
type is 64 bits large while its 'long' is 32 bits. Use the
\fICURLINFO_ACTIVESOCKET\fP instead, if possible.
.IP CURLINFO_ACTIVESOCKET
Pass a pointer to a curl_socket_t to receive the active socket used by this
curl session. If the socket is no longer valid, -1 is returned. When you
finish working with the socket, you must call curl_easy_cleanup() as usual and
let libcurl close the socket and cleanup other resources associated with the
handle. This is typically used in combination with
\fICURLOPT_CONNECT_ONLY(3)\fP.
NOTE: this is meant as a cross-platform, safe alternative to
\fICURLINFO_LASTSOCKET\fP, which does not work on win64.
.IP CURLINFO_FTP_ENTRY_PATH
Pass a pointer to a char pointer to receive a pointer to a string holding the
path of the entry path. That is the initial path libcurl ended up in when
