[scobiej]

Port to allow clean build on OSX
Cleanup compiler warnings on later level gcc
Clean build on CentOS7
Fix OpenSSL >= 1.1 compatibility

Time to merge? :-)

I tried this out and it also works without warnings with OpenSSL 3.0.9 (Debian bookworm).

Somehow the Using OpenSSL 3.0.9 from the message (which I see when editing it) disappears once I update the comment. So that's the exact version in my case.

This still works, even with OpenSSL 3.3.0! I'd love to have it merged :)
