*2 = requires OpenLDAP
*3 = requires a GSS-API implementation (such as Heimdal or MIT Kerberos) or
SSPI (native Windows)

currently supported
*5 = requires nghttp2 and possibly a recent TLS library
*6 = requires c-ares
*7 = requires OpenSSL, NSS, GSKit, WinSSL or Secure Transport; GnuTLS, for
example, only supports SSLv3 and TLSv1
