--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Why can't you just use a global object with a constructor and destructor? T=
hat
would get correctly ordered with respect to the std::ios_base::Init object =
that
needs to be created before std::cout can be used.

The constructor and destructor attributes not necessary in C++, and are
documented as having an unspecified order relative to global objects (like =
the
std::ios_base::Init one).=
