 Could it be that it is failing due to a typo?

 There aren't so many files that include a `*atomic.h` header file. Those
 that do so are named "kmp_*.c, except one: kmp_lock.h. It includes an
 `<atomic>` C header file from some standard path for C header files.

 This `atomic.h` file can be something new – Snow Leopard (Mac OS X
 10.6.8), PPC Leopard (Mac OS X 10.5.8), and PPC Tiger (Mac OS X 10.4.11)
 do not have such a file.

 `#include <atomic>` can be a typo, standing for `#include "kmp_atomic.h"`…
 What is in the previous version containing?

 If it's not an error than it might be worth to try a guard allowing
 inclusion only on Mountain Lion and later…
