Ah, I missed a use of that attribute within Gnulib when installing the recent
changes for __has_attribute. I installed the attached patch to fix it, and the
followup two patches (also attached) to fix some style nits I noticed while
fixing the bug. Thanks for reporting it.

Hello again,
looking at Hydra/Nixos, the autobuild system failed due to commit c08f85d
made three days ago to gnulib, and it has not recovered since then.
This seems to correspond to my report.
Regards,
Mats E Andersson
