Attached is a patch which implements the above feature. I was a
surprised to find that negative integers don't wrap around in C as
they do in Ruby:

C:
 -4 % 4 => 0
 -3 % 4 => -3
 -2 % 4 => -2
 -1 % 4 => -1
  0 % 4 => 0
  1 % 4 => 1
  2 % 4 => 2
  3 % 4 => 3
  4 % 4 => 0

Ruby:
 -4 % 4 => 0
 -3 % 4 => 1
 -2 % 4 => 2
 -1 % 4 => 3
  0 % 4 => 0
  1 % 4 => 1
  2 % 4 => 2
  3 % 4 => 3
  4 % 4 => 0
