Friday I did try to build Stunnel 5.17 with Linux Mint x86_64 (as a VM in
Win7 x64) and compiling OpenSSL 1.0.2a. I did remember getting some errors
for SSLv2 with Stunnel 5.17. I'll try and do this again when I get home. I
was going to try the latest OpenSSL 1.0.1m (latest 1.0.1 IIRC) but same
thing with Stunnel 5.17.

I did notice that it appears that all Debian repositories still use the
insecure and vulnerable OpenSSL version, which demanded that I build the
OpenSSL myself.
