 {

    //  The intent is to propose the following for addition to namespace std

    //  in the C++ Standard Library, and to then deprecate EXIT_SUCCESS and

    //  EXIT_FAILURE.  As an implementation detail, this header defines the

    //  new constants in terms of EXIT_SUCCESS and EXIT_FAILURE.  In a new

    //  standard, the constants would be implementation-defined, although it

    //  might be worthwhile to "suggest" (which a standard is allowed to do)

    //  values of 0 and 1 respectively.

    //  Rationale for having multiple failure values: some environments may

    //  wish to distinguish between different classes of errors.

    //  Rationale for choice of values: programs often use values < 100 for

    //  their own error reporting.  Values > 255 are sometimes reserved for

    //  system detected errors.  200/201 were suggested to minimize conflict.

    const int exit_success = EXIT_SUCCESS;  // implementation-defined value

    const int exit_failure = EXIT_FAILURE;  // implementation-defined value

    const int exit_exception_failure = 200; // otherwise uncaught exception

    const int exit_test_failure = 201;      // report_error or

                                            //  report_critical_error called.
