--- Comment #3 from Jiang An <de34 at live dot cn> ---
IIUC GCC and libstdc++ are doing the right thing - you're just not allowed to
customize comparison for float.
You wrote `using std::strong_order;` first, and std::strong_order is a function
object, so the name lookup won't furtherly find functions of name strong_order.
In the body of the operator() of the type of std::strong_oder, ADL is
effectively not performed because the arguments are of floating-point type and
have no associated namespace.
