Well, why don't you do something like adding an extra pair of braces
before and after the loop like:

  {
  int i;
     do {
       .
       .
     } while (1);
  }

this should limit the scope of i in the loop and clear the ambiguity
of whether i is re-allocated every time round the loop.
** Seem obvious to me.
