! { dg-do run }
! { dg-options "-cpp -fdec-format-defaults" }
!
! Test case for the default field widths enabled by the -fdec-format-defaults flag.
!
! This feature is not part of any Fortran standard, but it is supported by the
! Oracle Fortran compiler and others.
!
! Test case added by Mark Eggleston <mark.eggleston@codethink.com> to check
! use of -fdec-format-defaults
