// This is a fake version of Clang / libc++'s <__config> header. The <__config>
// header provides various _LIBCPP defines used internally by libc++.
//
// In particular, pw_polyfill and pw_minimal_cpp_stdlib need the macros that
// provide the namespace to use for standard library definitions. This header
// provides _LIBCPP_BEGIN_NAMESPACE_STD and _LIBCPP_END_NAMESPACE_STD.
