Hi Steve,

Since Curl_ntlm_sspi_cleanup() is defined to nothing on some systems we get a
warning in curl_sasl.c and I was thinking perhaps we can add something like
the following to avoid the warning:

curl_sasl.c:195:44: error: unused parameter 'conn' [-Werror=unused-parameter]

The patch that works for me and I think would work on windows as well:

diff --git a/lib/curl_sasl.c b/lib/curl_sasl.c
index e9a3c18..407386d 100644
--- a/lib/curl_sasl.c
