      The flag unsafe-loop-optimizations is currently set when GCC version is 4.7, 5.x or 6.x. This triggers a warning when trying to compile c++ files that use range based for loop:

      ../../../test/cppsuite/test_harness/thread_manager.cxx: In destructor 'test_harness::thread_manager::~thread_manager()':
      ../../../test/cppsuite/test_harness/thread_manager.cxx:35:21: error: missed loop optimization, the loop counter may overflow [-Werror=unsafe-loop-optimizations]
           for (auto &it : _workers) { 

      This flag should be disabled when compiling c++ files.
