Well.... the answer it appears is trial and error, here's what I have so 
far (which is enough to get the tests passing for now):

clang 5:
* No <regex> prior to gcc-5.x
* No thread_local prior to gcc-4.8.x (ABI/linker issues)

Clang 3.x:
* No <future>, <mutex>, <condition_variable> or <chrono> prior to gcc 
4.8 (these are all failures to compile <chrono>)

There may be other issues with old clang and newer gcc, but I haven't 
tested that combination yet.

Thanks, John.
