! Error test -- DO loop uses obsolete loop termination statement
! See R1131 and C1133
! By default, this is not an error and label do are rewritten to non-label do.
! A warning is generated with -Mstandard
! RUN: ${F18} -funparse-with-symbols -Mstandard %s 2>&1 | ${FileCheck} %s
! CHECK: end do
! The following CHECK-NOT actively uses the fact that the leading zero of labels
! would be removed in the unparse but not the line linked to warnings. We do
! not want to see label do in the unparse only.
! CHECK-NOT: do [1-9]
! CHECK: A DO loop should terminate with an END DO or CONTINUE
