|  |    //  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.
