> Officially, neither `static_assert` nor `is_trivially_copyable` are present in C++11. `test/libcxx/containers/sequences/vector.bool/trivial_for_purposes_of_call.pass.cpp` is unsupported in C++03 and I can't see any reason it would be unsupported //except// for its reliance on the `is_trivially_` type-traits.
libc++ provides many of these things in C++03. Even rvalues and variadics work.
