Yes, I made the same observation. It seems to be a simple int value
which is incremented for struct/interfaces changes.

Yes, that's a good idea. I added a new function called
Curl_sspi_version to curl_sspi.[ch] to the product version of the
loaded DLL. This is based upon version.lib, which is available since
Windows 2000 Professional or Windows 2000 Server.

Inside curl_schannel.c the string is appended to "Schannel-", so that
a complete version string looks like this:

D:\Dev\curl>src\curl -V
curl 7.25.1-DEV (i386-pc-win32) libcurl/7.25.1-DEV Schannel-SSPI/6.1.7601.17725
Protocols: dict file ftp ftps gopher http https imap imaps ldap pop3
pop3s rtsp smtp smtps telnet tftp
Features: AsynchDNS GSS-Negotiate Largefile NTLM SSL SSPI

I have attached two patches, schannel_2012-04-14_1.patch includes
everything and schannel_2012-04-14_1_diff.patch only the changes since
my last patch.
Git repository is also up-to-date:
