Adds a new option, `handle_winexcept` to try to intercept uncaught Visual C++ exceptions on Windows. On Linux, such exceptions are handled implicitly by `std::terminate()` raising `SIBABRT`. This option brings the Windows behavior in line with Linux. Unfortunately this exception code is intentionally undocumented, however has remained stable for the last decade.
