|  |    //  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. | ||
