        * resolve.c (gfc_resolve_code): Simplify condition for class
        pointer assignments becoming regular assignments by asserting
        that only class valued targets are permitted.
        * trans-expr.c (trans_class_pointer_fcn): New function using a
        block of code from gfc_trans_pointer_assignment.
        (gfc_trans_pointer_assignment): Call the new function. Tidy up
        a minor whitespace issue.
