The list accepts attachments, but thanks anyway. And please stop top
posting. ;-)

Please try adding USE_OPENSSL to the definitions. It seems like
openssl/md5.h is only included in case that is defined.

Windows SSL uses the native SSL/TLS implementation provided within
Windows as part of the Schannel API. The support for this in curl is
relatively new and not tested as long as the OpenSSL code. So it
might be a bit unstable. Otherwise it does not yet support all
features that OpenSSL offers, like client certificate authentication
support or specifying the algorithms to use. An advantage would be
that you do not have to ship the OpenSSL binaries with your program.
