<pre>Hi!
So - libc++ in it's documentation claims to support clang3.5
Unfortunaly, when compiling the benchmarks for the library with clang3.9 - we
get a compiler error because of -std=c++17:
<a href="https://github.com/llvm-mirror/libcxx/blob/master/benchmarks/CMakeLists.txt#L71">https://github.com/llvm-mirror/libcxx/blob/master/benchmarks/CMakeLists.txt#L71</a>
This is important because there are performance issues that arise with previous
versions of clang and it's a good idea to run benchmarks on those too.</pre>
