> Almost there. The file now compiles, but a failure occurs in a later step due to compression functionality being unavailable:

> It looks as if OPENSSL_NO_COMP needs to be defined in _ssl.c if the OpenSSL version is too old and not already defined. With this change:
> #if OPENSSL_VERSION_NUMBER < 0x0090800fL && !defined(OPENSSL_NO_COMP)
> # define OPENSSL_NO_COMP
> #endif
> the ssl library builds without errors. However, test_ssl fails because it still expects OP_SINGLE_ECDH_USE to be defined. With this change in test_constants:
>         if ssl.HAS_ECDH:
>             ssl.OP_SINGLE_ECDH_USE
> all tests pass.
> I notice that the test there for OP_NO_COMPRESSION is version-based rather than capability-based, and it might be a good idea to change this too.
