clang has exactly the same behavior for x86_64-windows-gnu and
x86_64-windows-msvc (only name mangling is different.) However
x86_64-windows-gnu indicates the abi defined by GCC, clang should match the
behavior of GCC or not the way around? Or GCC should match the behavior with
msvc? but they do not use the same thread model.
