Intel claims full C++11 support as of version 15.0, so that should be ok.

They should certainly be fine.

I am well aware of that. But C++14 is currently a no-go -- even if we
could rely on all of our users (those that want to run their own builds
at any rate) having access to a C++14-capable compiler, we're still
stuck with MSVC 2015, GCC 4.8.4 and clang 4.2 on the machines we run our
automated build tests on; of those, only clang will do a reasonable
subset of C++14. You do want us to run automated build tests, don't you? ;)

As a matter of fact, one of our automated build services (the one we
also happen to need to run our automated static code analysis) is still
running Ubuntu 12.04 by default, with GCC still at 4.6 and thus not even
C++11-complete. It was only recently that I learned that they do provide
14.04 images, but they still seem to flag them as beta.
