 avoid ambiguous use of abs() causing build failure.
 Avoid failing build with GCC 7 due to abiguous use of abs(unsigned int).
 The problem is this:
   unsigned int a, b, c; c = abs(a - b);
 The type of a - b here is unsigned int, and abs(unsigned int) do not
 exist.  I solved it by changing the calculation to use signed long
 instead, as abs(long) exist and should be able to handle the entire
 value range.
