Dear GRUB folks,
On Debian sid/unstable clang 13.0.1 fails to build GRUB due to a problem
in Gnulib:
```

I tried to use latest Gnulib (not the one defined in `bootstrap.conf`),
but the error remains.
How to deal with that, if I am unsure how to fix it? Report it to the
Gnulib folks?
Kind regards,
Paul
