Hi Eli,

I had to travel urgently and had trouble testing this on my Mac OS X
laptop; it took me a while to build all the pieces. Sorry for the delay.

Using a Ubuntu 17.04 Docker image, I compiled GnuTLS from source (a
GnuTLS 3.4.15 dev package was not available) and all the GnuTLS Emacs
tests passed in master against it (see summary and Dockerfile attached
below). A few of the Emacs tests failed in master, but that was not
related to GnuTLS.

Can you give me a recipe to reproduce the problem with your distribution
and packages? It may be irreproducible in Docker, or I tested
incorrectly, or maybe there's something specific about the optimizations
of the packaged libraries.
