  return 1;
}
int main (void)
{   
  int i;
  for (i = 4; i--;)

I think this is an ivopt bug:
  if (i_3 != 4294967295) goto <L0>; else goto <L10>;


i_3 is signed but the expression (I think), 4294967295, is unsigned, maybe we are missing a 
fold_convert.

> http://gcc.gnu.org/ml/gcc-patches/2005-02/msg00657.html

it may be worth noting that compare for equivelence/non-equivelence,
is insensitive to the sign of equivelent rank integers, although relative
(< >) compares are, but it does'nt seem that it's recognized when
comparision operations are constructed?

I don't understand the comment.  Comparisons constructed due to
may_eliminate_iv are always either EQ_EXPRs or NE_EXPRs.  Comparing
directly with a value in a different type (regardless of what comparison
operator is used) is however always an invalid gimple.

Yes you're correct, my comment was misguided, and simply wrong.
