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