Debian 4.19.160-2 (2020-11-28) x86_64 GNU/Linux
gcc (Debian 8.3.0-6) 8.3.0

So I guess I'm on an "old" compiler compared to 11.2.1

I'm not seeing that on Fedora 35 x86-64, with GCC 11.2.1 20220127 (Red
Hat 11.2.1-9). If you're using an older compiler, I suggest configuring
with --disable-gcc-warnings, or building with "make WERROR_CFLAGS=", so
that the unnecessary warnings don't break the build. If you're not,
please specify the platform and GCC you're using, and how you ran
'configure' and 'make'. Thanks.
