In testing gfortran's capacity to deal with iso_varying_string, it was found
that the error "Specification function 'len_' at (1) must be PURE" was produced
- see testcase below. This is obviously incorrect because elemental functions
are pure.
The patch and the testcase appear below.

! { dg-do compile }
! Tests the fix for elemental functions not being allowed in
! specification expressions in pure procedures.
!
! Testcase from iso_varying_string by Rich Townsend <rhdt@star.ucl.ac.uk>
! The allocatable component has been changed to a pointer for this testcase.
!
module iso_varying_string
type varying_string
private
character(LEN=1), dimension(:), pointer :: chars
end type varying_string
interface len
module procedure len_
end interface len
contains
pure function char_auto (string) result (char_string)
type(varying_string), intent(in) :: string
character(LEN=len(string)) :: char_string ! Error was here
end function char_auto
elemental function len_ (string) result (length)
type(varying_string), intent(in) :: string
integer :: length
end function len_
end module iso_varying_string
