No Useless Implied-DO
---------------------

   An array element initializer in an implied-`DO' construct in a
`DATA' statement must contain at least one reference to the `DO'
variables of each outer implied-`DO' construct.  For example, this
fragment is disallowed by `g77':

     DATA (A, I= 1, 1) /1./

This also is disallowed by Fortran 90, as FORTRAN 77's more permissive
requirements offer no additional capabilities.  However, `g77' doesn't
necessarily diagnose all cases where this requirement is not met.

   Note that it is *very* unlikely that any production Fortran code
tries to use this unsupported construct.
