Did you perhaps branch off of the libc-0.2 branch but submit a PR against main?

I'm very sorry, I have edited it.

[tgross35]

Wrong way; please branch from and target main :)

I just hope to make a patch to 0.2.174 and release 0.2.175 in due course, otherwise I will close this PR.

Everything targets main by default so we don't lose the changes once 1.0 gets released. You can add the stable-nominated label to request a backport (usually I add the label to everything possible if it gets missed)

[fxdmhtt]

Ok, I'll commit next time when I have more changes merged.

No need; the change here is fine, you just need to rebase on top of main (and change the PR target branch)
