Hello Karel,
the set of tool builds below was run for RTEMS 6, with RSB
GIT_HEAD 0054104e37aa870aab87294207fc20396312106f. Your comment on me
using GCC 12 on some OS, which would natively use an older GCC version,
triggered me to add more OS containers to the build set. This way the
different GCC variants are better covered in the future.
opensuse-leap 15.4 (gcc 7.5.0, Python 3.6.15) x86_64 : OK
almalinux 9.1 (gcc 11.3.1, Python 3.9.14) x86_64 : OK
almalinux 8.7 (gcc 8.5.0, Python 3.6.8) x86_64 : OK
fedora 37 (gcc 12.2.1, Python 3.11.2) x86_64 : OK
debian 11 (gcc 10.2.1, Python 3.9.2) x86_64 : OK
opensuse-leap 15.4 (gcc 12.2.1, Python 3.6.15) x86_64 : OK
ubuntu 22.04 (gcc 11.3.0, Python 3.10.6) x86_64 : OK
ubuntu 20.04 (gcc 9.4.0, Python 3.8.10) x86_64 : OK
ubuntu 22.04 (gcc 12.1.0, Python 3.10.6) x86_64 : OK
Your fix works perfectly. All errors are gone.
Thanks for your time and effort to fix the failing builds.
Greetings
Frank

The build failures all happen when `building:
grub2-2.06-x86_64-linux-gnu-1` which is the last build step. There are
several similar errors. These are two of them taken from the build log:

Maybe one needs a new version of grub sources for gcc 12?
GRUB 2.06 is the last available release. The release cadence is 2 years
and next version should be released around this summer. I would not like
to go to git version in the meantime, but rather stick to released version.
Possible and working (tested on Fedora 37 and Ubuntu 20.04) workaround
is to use --disable-werror as all the related errors are just warnings.
The patch already sent, testing and reporting from your side would be
highly appreciated.
Thanks,
Karel
