Hmm. I have tested MSVC with 3.0.0 not so long ago, and this was
working, but maybe they upgraded from 1.0.2 to 3.0.0? I'd be
surprised if this was broken in some way in one of the stable releases
as well. We've had our share of surprises with OpenSSL when it comes
to major upgrades, but nothing that stood out when it came to minor
release compatibility and ABI, AFAIK.

openssl/ssl.h includes openssl/x509.h if OPENSSL_NO_DEPRECATED_1_1_0
is not defined, but agreed that adding the header makes sense here.

x509v3.h includes x509.h, so fe-secure-openssl.h would not need an
update. Now could it be a better practice to include both there?
