That's nice. But I run Linux.

Walter, surely this test shouldn't take more than a minute for you (or
anyone else with a D compiler installed). Just see what DMD outputs for:

  8  /   3
  8  / (-3)
(-8) /   3
(-8) / (-3)
  8  %   3
  8  % (-3)
(-8) %   3
(-8) % (-3)

If D uses DIV instead if IDIV, this should be immediately visible. In any
case, we will see exactly what kind of division and modulo D uses. You can
compare with the table on the bottom of page 3 of:

That's an informative article, by the way.
