The following declaration

 pure subroutine s_one ( anum, afun )
    integer, intent(in) :: anum
    interface
      pure function afun (k) result (l)
        implicit none
        integer, intent(in) :: k
        integer :: l
      end function afun
    end interface

results in the error (using lates build of gfortran-4.3):

Error: Argument 'afun' of pure subroutine 's_one' at (1) must have its INTENT
specified

The section 12.6 of ISO/IEC 1539-1 says:

Constraint: The specification-part of a pure function subprogram shall specify
that all dummy arguments have INTENT (IN) except procedure arguments and
arguments with the POINTER attribute.

which as far I understand means theat the code above is corrent (without intent
statement for 'afun'.

Cheers, T.
