--- Comment #61 from Andrew Church <achurch+gcc at achurch dot org> --- For the record, I'll maintain a copy of my (unaccepted) patch to add -Wunused-result=strict at: https://achurch.org/patch-pile/#gcc (wur-strict.diff) This flag obviously shouldn't be relied on in released packages, but it may be helpful for individual users trying to work around this issue.
