+! Check for the expected behaviour when an intrinsic function/subroutine is
+! called that is not available in the defined standard or that is a GNU
+! extension:
+! There should be a warning emitted on the call, and the reference should be
+! treated like an external call.
+! For declaring a non-standard intrinsic INTRINSIC, a hard error should be
+! generated, of course.
