 * The OpenACC specification disallows a variable from appearing multiple times
   in clauses of `!$acc declare` directives for a function, subroutine, program,
   or module, but Flang permits it with a warning when the same clause is used.
+* The REDUCTION clause accepts a MINUS "-" operator which is not permitted in
