--- Comment #6 from Damian Rouson <damian at sourceryinstitute dot org> --- Sounds good. I agree that it would be great for gfortran to provide ISO_Fortran_binding.h independently. Hopefully the OpenCoarrays version will be a useful starting point. My understanding is that it's always ok to copy source code from a BSD-licensed project such as OpenCoarrays into a GPL-licensed project so hopefully our implementation saves someone a lot of time. The only remaining challenge is to coax the GCC build system into install it. Obviously that should be a trivial task for someone with the right knowledge or the patience to figure it out. I just don't know who that person is and we did reach out to several people for help and even got some input, but still couldn't get it to work.
