So, if I understand correctly the (fixed) logic, it is:
  f2008+    => no check
  f2003     => check target’s rank different from 1
  up to f95 => check pointer’s rank equals target’s


I think one check is missing, that is when pointer is scalar and the 
target is non-scalar (either rank 1 or not).  This case should also be 
rejected for f2003+, not just up to f95.
