+       * dependency.c (check_section_vs_section):  Pre-calculate
+       the relationship between the strides and the relationship
+       between the start values.  Use an integer constant one for
+       that purpose.
+       Forward dependencies for positive strides apply for where
+       the lhs start <= rhs start and lhs stride <= rhs stride
+       and vice versa for negative stride.  No need to compare
+       end expressions in either case (assume no bounds violation).
