1038    These defines enumerate the minimum and maximum values of this range.
1039    Currently only the maximum value is used (to indicate that 64-bit
1040    values are going to be used in the dwarf data that accompanies the
1041    structure).  The other values are reserved.

1043    Note: There is a typo in DWARF3 spec (published Dec 20, 2005).  In
1044    sections 7.4, 7.5.1, 7.19, 7.20 the minimum escape code is referred to
1045    as 0xffffff00 whereas in fact it should be 0xfffffff0.  */
