do while does not have the same behavior, so the loop "shape" is important.
the following is as bad and does not have function calls.
#define ONE while (x-- > y)
#define TEN ONE ONE ONE ONE ONE ONE ONE ONE ONE ONE
#define HUN TEN TEN TEN TEN TEN TEN TEN TEN TEN TEN
#define THOU HUN HUN HUN HUN HUN HUN HUN HUN HUN HUN
void foo(int x, int y)
{
/* 11,000 nested whiles. */
THOU THOU THOU THOU THOU THOU THOU THOU THOU THOU THOU
y++;
}
