I cannot reach Dmitrij since months so we probably should not wait for his OK.

Thanks, works fine for me. `make test` gives the same results as yours
(I did not investigate the one failing test.)

I will commit the update within the next days unless I hear objections.

In case you are using baresip (the only consumer of libzrtp in our ports
tree): there is now a module gzrtp
(https://github.com/alfredh/baresip/tree/master/modules/gzrtp) which
uses the GNU ZRTP implementation
(https://github.com/wernerd/ZRTPCPP) which is maintained. ZRTPCPP builds
fine on OpenBSD (with fixes reported by me upstream and already
committed in the `develop` branch) but requires the full sources to be
present in the baresip build directory (see e.g.
http://lists.creytiv.com/pipermail/re-devel/2018-February/001168.html).
I.e., a separate port would not work at the moment (as some files would
be missing). In case anyone has interest in gzrtp please contact me to
avoid duplicated efforts.
