ISO_Fortran_binding patch

I notice that the header file ISO_Fortran_binding.h is found twice
in the patch.

Is there any particular reason why you do not want to use

! { dg-additional-options "-I $srcdir/../../libgfortran" }

in the test cases, and have it only once in the source trees?

However, I have no real strong opinion on this matter, if you
want to keep it as submitted, it is also fine.

Therefore: OK for trunk, and thanks a lot for the patch!

Documentation we can add at a later date, I think.

Regards
