CMakeCCompilerId.c

cmake based projects are failing to compile using clang 3.8.1 on Mountain Lion
(newer versions aren't currently building on Mountain Lion, so I'm not sure if
this is fixed).  In comparison, clang 3.7.1 works fine.

As this fails during preprocessing, I cannot provide preprocessed source.

This issue does not occur with clang-3.8.1 on Sierra with the same input
