Yes, we could do that, but I do not think we should check for the 
existence of a backwards compatibility macro. Actually I think we may 
want to skip much of the OpenSSL initialization code when compiling 
against OpenSSL 1.1 since they have now added automatic initialization 
of the library. Instead I think we should check for something we 
actually will use like SSL_CTX_new().
