c9e1ad7f for example, which is the last thing I could come up with.
Navigating through the logs of the buildfarm, it is actually not really
easy to find out which version of OpenSSL a build is using at compile
time.  Perhaps we would want first to report this information?
SSLeay_version is here for configure, while we could use a call to
"openssl version" for the MSVC scripts.

Actually, it seems that to me that SSL_OP_NO_COMPRESSION should also be
added..  Making HAVE_X509_GET_SIGNATURE_NID a hard requirement bumps the
minimal version of OpenSSL supported to 1.0.2, which is something I
would not feel much sorry about either like Heikki, as I have heard of
many vendors maintaining OpenSSL past versions on Linux, but not yet on
Windows.  It is easy to be wrong when it comes to any company policies
though.
