                      4:  * This header file defines:

                      6:  *     the base of the machine dependent variant bits,
                      7:  *     the maximum number of variant bits,
                      8:  *     the typedef of the variant array,
                      9:  *     and a macro to access the variant bits.
                     10:  * The variants are passed to the compiler phases as a string of
                     11:  *     hexidecimal digits.
