The Windows C++ runtime requires C++14. This is handled transparently when using the `clang-cl` driver, however, when building with s-p-m, the `clang` driver is used instead. This requires explicitly bumping everything to C++14.

@akyrtzi @benlangmuir - I'm not sure if this is acceptable or not. I couldn't figure out a way to do a build condition on the setting here, which would be another option otherwise. But, the current MSVC C++ STL headers use C++14 features unconditionally. |
