According to that URL from NetBSD that I posted above, they are still using

Since I was CCed in this discussion - can I ask why qemu is targeting
compiler versions instead of C standard revisions?
Hi!
QEMU already uses std=gnu11. The problem is that different compiler versions
emit different warnings, and with older compilers, there are often warnings
that are false positives (see e.g.
https://lore.kernel.org/qemu-devel/[email protected]/ that just has
been posted to the mailing list recently). The QEMU project tries to avoid
supporting operating systems / build environments that are too old (see
https://www.qemu.org/docs/master/about/build-platforms.html), we often just
don't have the capacity in the developer community to handle that, so that's
why we put compiler checks into place to avoid wrong expectations for the users.
