OpenBSD 6.2 shipped with LLVM/Clang 4.0.0 and OpenBSD 6.3 will ship
with at least LLVM/Clang 5.0.0 as the system compiler on amd64, arm64
and i386.  We're planning to switch armv7 over as well, and may
provide Clang alongside GCC for mips64 and sparc64 as well.

So for us a more relevant question is whether Clang 4 or Clang 5 has
sufficient C++14/17 support.
