Hi!
There was a lot warning during build wold and kernel in past with clang 13,
but with clang 14 to many warnings.
Probably commiters will find some time to fix it?
I spent some time to fix/supress warnings for world, exept contrib and stand parts.
This patch is not to merge, it is to show that something goes wrong.
