Thanks, assuming clang by default on OSX indeed seems like a reasonable
solution.
We also have that issue with GCC5's C++ ABI change
(http://developers.redhat.com/blog/2015/02/05/gcc5-and-the-c11-abi/), so
detecting the actual compiler might be helpful as well.

Yes, would be good if we updated the auto-testers to use clang @Brad.
