! 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.
