* natural_t and integer_t are Mach's legacy types for machine-
* independent integer types (unsigned, and signed, respectively).
* Their original purpose was to define other types in a machine/
* compiler independent way.
*
* They also had an implicit "same size as pointer" characteristic
* to them (i.e. Mach's traditional types are very ILP32 or ILP64
* centric). We support x86 ABIs that do not follow either of
* these models (specifically LP64). Therefore, we had to make a
* choice between making these types scale with pointers or stay
* tied to integers. Because their use is predominantly tied to
* to the size of an integer, we are keeping that association and
* breaking free from pointer size guarantees.
*
* New use of these types is discouraged.
