--- Comment #14 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Is there any way to do multiline comments in gfortran?

Am attempting to write expected output like this:

! { dg-begin-multiline-output "" }
EXPECTED OUTPUT TO GO HERE
! { dg-end-multiline-output "" }

If not, I may need to require every line within the begin/end to start with a
  "! "
and to strip that.
