Thanks for looking into this.  I'll try to change the pointer arithmetic
as you suggest.  B.t.w. I'm not quite sure in any case how exactly types
of integral expressions need to be handled: in a PLUS_EXPR or MULT_EXPR
node, do I need to have all operands converted to exactly the same type,
or are integral conversions automatic?  What about a PLUS_EXPR with a
pointer and an integral operand?
