The intention here is eliminating linking to OpenSSL. That done, not
even Gabber exception would be needed.

Unfortunately, the compatibility layer does not implement the entire
API. There is a good chance this approach will fail without considerate

I suggest disabling SSL/TLS support in Gabber, if it's possible with a
simple building switch. Since it's an obsolete software and there are
many alternatives, I don't think this will hurt.

Meanwhile, I have tried to build wget with gnutls and, although it has
failed, I could start improving the OpenSSL compatibility support in GNU
TLS. Perhaps that could help some other software that seem to have the
same problema, like mail-notify.
