/*! \file
The <stdint.h> header gives us types of a known width and signedness, like
uint32_t and int16_t. These types can be very useful for
matching the internal types of a processor, and for managing
conversions from signed to unsigned types. The C/C++ standard has certain
(very strict) rules for conversion between types, which are different from
the rules of any particular CPU. In an extremely legalistic interpretation, the
integer encoding is not necessarily twos complement, but we
will mandate that all target architectures use a twos complement
representation.
