[Bug fortran/41704] New: Different local names in interfaces for same C-binding name/same procedure

[burnus at gcc dot gnu dot org]

Gfortran rejects the following code with
  Error: Binding label 'foo' in interface body at (1)
         collides with the global entity 'foo' at (2)
However, it seems as if the code could be valid - either in Fortran 2003 or in
Fortran 2008. See thread at
http://groups.google.com/group/comp.lang.fortran/browse_thread/thread/02a37fa283e0ef25

One could consider sending an interpretation request.


use iso_c_binding
interface
    function foo_1() bind(c, name='foo')
      import
      integer(c_int) :: foo_1
    end function
    function foo_2() bind(c, name='foo')
      import
      integer(c_int) :: foo_2
    end function
  end interface
end

[Bug fortran/41704] [F2008?] Different local names in interfaces for same C-binding name/same procedure

The thread doesn't come to a conclusion. As I read it, it's invalid in F2003,
but maybe valid in F2008?! Thus removing the rejects-valid keyword for now.
