How could  this be? If "int" is implemented by compiler A as
being 16 bits, and by compiler B as 32 bits, how can you have
one simple interface?

Older compilers for the PC platform could easily have created 
legacy code in which in the calling conventions are based on
earlier processors (integer was 16 bits for the Meridian Ada 
compiler), while newer compilers produce 32 bit integers.
