Version number is removed in order to make this info consistent with how we do it with other MS and Linux system libraries for which we don't provide this info. Identifier changed from 'WinSSPI' to 'schannel' given that this is the actual provider of the SSL/TLS support. libcurl can still be built with SSPI and without SCHANNEL support.
