Thanks for the information. I don't have time to support newer versions of OpenSSL right now, so if anyone wants to give this a go (use shim.c and shim.h to select correct implementations based on the OpenSSL version defines), then I'd be happy to review and merge it.

@ngashok builds okay with 1.1.1d (not 1.1.1g).
