With my recent commits that use more OpenSSL 1.1.1 features building
with LibreSSL breaks again since it claims to be OpenSSL 2.0 or
something ridiculous like that. In my book claiming to support APIs you
don't even know is a bad move.

With the current situation I would also ACK this patch. I see no good
way at the moment for supporting LibreSSL.

As an OpenBSD developer and the maintainer of our OpenVPN port,
I certainly care about building and using OpenVPN with LibreSSL.
I have already provided patches in the past, and yesterday I pushed
compat glue in LibreSSL so that openvpn-2.4.5 can build on OpenBSD
(-current).

So I'm wondering what would be needed to consider LibreSSL "supported".

I hear that there are concerns over LibreSSL not being API-compatible
with OpenSSL.  As you may have noticed, LibreSSL recently introduced
lots of OpenSSL-1.1+ interfaces.  While there is no plan to support the
full OpenSSL-1.1 API (tons of functions were added, not all of them seem
useful...), the intent is to provide what the ecosystem actually needs.
I can probably serve as a bridge between the two projects here.

If you see other points where I - or anyone else - can help, please
share. :)

I considered that (modulo the sleep 60) and wrote the code to do the
configure check, but then thought that a not-suppressible warning in the
logs would be sufficient.  I still think it is, but don't mind re-adding
it to configure.ac if you prefer that.

Generally speaking, I agree.

Should we also add a warning (+ sleep 60 to be extra-annoying?) to
configure if LibreSSL is detected?

Gah, this of course needs a ; at the end of the line - forgot to amend
the commit before git send-email...
