"This solution is a portable (i.e. Ada83/Ada95) solution, based on the
assumption that Ada's System.ADDRESS and C's pointer are the same size, and
have identical representations, and that Ada's INTEGER type and C's size_t
type are the same size, and have identical representations. These
assumptions are usually true."
The size_t assumption is very dangerous, it will typically NOT be true
on any 64-bit machine, for example it is false in the DEC Unix
implementation of GNAT.
