Re: Patch to prevent multiple _POSIX_C_ declarations

[Barak A. Pearlmutter]

I think that issue is already addressed by a commit in the savannah
git repo, c83f214a2, which is from 12-Aug-2026 and is currently at
master~3.
That's the development branch though.
Debian hit the same issue and has a patch to 12.1 for it, which just
deletes the #define from src/microcode/chacha.i
