Changelog
+
+Daniel (19 September)
+- Applied Markus Moeller's patch that introduces SPNEGO support if libcurl
+ is built with the FBopenssl libraries. curl_version_info() now returns
+ info on SPNEGO availability. The patch also made the GSSAPI stuff work fine
+ with the MIT GSS-library (the Heimdal one still works too).
