Thanks for these fixes. So I tried just building on my current system
(Ubuntu 14.04 LTS) and it failed to compile, with only GnuTLS 2.12.23.
I think the following three functions are the problematic ones right now
(introduced with various versions > 3).
Can you clarify again what version we should be using and I guess, how
to proceed from here?
