yes, that would be ideal.

But anyone using gcc 13 in the meanwhile will have a broken build

and any other aspect of testing the kernel with gcc 13 would have

to be deferred to after the fix, if it happens.

With W=1, there are 40 error:'s, sorry I do not have the default logs at 
hand.

I looked about 10 of them over the weekend, they we all bogus.

So gcc needs to be fixed first, just disabling with -Wnoerror will

give folks bad problems that do not need fixing.


I am asking that we at least temporarily disable this option so

the build break is fixed.
