We've hit the confusion between the two ways of using integral here, my
use above (defined as part of the language) and the language definitions
use (relating to integer data types).

By integral I meant those data types defined as part of the language:-
char, int, short, long, float, double, etc...

I should have said "fundamental" rather than "integral"
to avoid the
confusion. My error, Sorry...

I forgot about structs/unions when I wrote that :-(

I should have defined it the other way about (arrays passed by
reference, everything else by value) and then I wouldn't be causing the
confusion...
