Hey.
One small note: can you please link the next v4 email thread to this one?
It's much easier to follow all the discussion related to your patch set.
Thanks,

And another update; I removed the global variable, which
was only used for checking at the end – and
reconstruct its value in a local variable just before calling
gfc_check_omp_requires.
(Following a suggestion by Jakub and removing a kind-of left

Thanks for doing this. +1 for the best fix being to add XFAILing tests
to the main testsute, enabled by default. I don't see any other realistic
way of ensuring that fixes are matched with PRs at the time that the fix
is made (rather than some time after the fact).

This patch does not implement anything new, but simply separates OpenACC
