I think that exclusive MAX_ORDER is more intuitive in the C language -
i.e. if you write "for (i = 0; i < MAX_ORDER; i++)", you are supposed to
loop over all allowed values. If you declare an array "void
*array[MAX_ORDER];" you are supposed to hold a value for each allowed
order.
Pascal has for loops and array dimensions with inclusive ranges - and it
is more prone to off-by-one errors.
I agree it's somewhat confusing either way but the ship has sailed, the
patch has been included in Linux for several months.
