Iff GCC 5 compiled offloaded OpenACC/PTX code will always do host fallback anyway because of the incompatible PTX version, then why don't you just do goacc_save_and_set_bind (acc_device_host); fn (hostaddrs); goacc_restore_bind (); and nothing else in GOACC_parallel?

Other than that, I think Bernd has covered all the issues I had.
What is your opinion on the forward compatibility issue? Is it something we care about?
