Christopher R. Palmer made it possible to build libcurl with the

USE_WINDOWS_SSPI on Windows, and then libcurl will be built to use the native
way to do NTLM. SSPI also allows libcurl to pass on the current user and its
password in the request.

Changelog
Daniel (11 March 2005)
- Christopher R. Palmer made it possible to build libcurl with the
USE_WINDOWS_SSPI on Windows, and then libcurl will be built to use the
native way to do NTLM. SSPI also allows libcurl to pass on the current user
and its password in the request.
Daniel (9 March 2005)
- Dan F improved the SSL lib setup in configure.
