ekam build seems to need c++14, not just c++11? about ekam

I think this is the same as #11.

What about -std=gnu++11?

For reference, here are some of the errors with c++11.

-std=gnu++11 seems to have the same problem.

Oops, that appears to be an issue in Cap'n Proto code. Specifically, some code I added fairly recently which I guess I never tested in C++11 mode.

I'm tempted to declare that Cap'n Proto now requires C++14, since there's some pretty big improvements that I'd like to rely on going forward...

FWIW bazel still seems to compile as C++11 by default. Maybe not that big a deal though -- it's easy enough to set custom compile flags in a bazel.rc or something.
