>From wolfssl/openssl/opensslv.h, and from skimming the contents of what
"--enable-stunnel" actually does, it seems that --enable-opensslextra
doesn't give you the "full" openssl compatibility that you may wish for
these days. Unfortuantely, while wolfssl writes the build time options
into wolfssl/options.h, it doesn't include that file itself. User
applications must include that directly.
