[Tom Honermann via Phabricator via cfe-commits]

Is it known what gcc and Microsoft maintainers are going to do with these DRs? I don't see any recent changes in gcc, but the following is interesting...

For the test below, Clang has historically accepted it but now rejects it. MSVC has historically rejected it, but started accepting it for v19.34 (perhaps a regression?). Gcc continues to accept it. See https://godbolt.org/z/jax3GsYY5.

  struct map {
    template <typename Sequence>
    map(Sequence&& seq , void* = 0 );
    template <typename First, typename ...T_>
    map(First&& first, T_&&... rest);
  };
  map m(0);
