It is usual for a pointer to require the largest width, while some
platforms might have an 'int' that is smaller than a pointer width.
This reverses the detection order to find.
Note since C99 there is <stdint.h> with type 'intmax_t' which
serves a similar purpose.
SonarCloud reports a concern with this on many lines where used.
"An integral type is too small to hold a pointer value."
