    libstdc++: Heterogeneous std::pair comparisons [PR113386]

    I'm only treating this as a DR for C++20 for now, because it's less work
    and only requires changes to operator=3D=3D and operator<=3D>. To do th=
is for
    older standards would require changes to the six relational operators
    used pre-C++20.
