// std::unexpected_handler is deprecated starting in C++11, and removed in
// C++17. But macOS versions we run on still ship it. This define makes
// std::unexpected_handler reappear. If that define ever stops working,
// we hopefully no longer run on macOS versions that still have it.
// (...or we'll have to define it in this file instead of getting it from
// <exception>). This define must before all includes.
