+// Hack to fix compilation with clang as tbb does not detect C++11 feature correctly for clang. Recent versions of TBB
+// allow to set the macro TBB_USE_GLIBCXX_VERSION to the proper version of libstdc++ to fix this issue, see
+// https://www.threadingbuildingblocks.org/docs/help/reference/appendices/known_issues/linux_os.html. For older versions
