Package: g++-13
Version: 13-20221214-1
Severity: serious

Hi Matthias,

thanks for pushing gcc-13 into experimental already. That leaves plenty
of time to work on it. I've located a quite fundamental problem with it
already:

$ cat test.c++
#include <stdio.h>
$ g++-13 -c test.c++

Jakub Jelinek kindly pointed out that bits/floatn.h and
bits/floatn-common.h should be fixincluded. I can see that this is
happening in a build log and that those fixed includes are not contained
in any binary package. As such, this is not considered an upstream
problem. I see that the packaging deletes include-fixed and fail to
understand why that happens at this time. Do you have a better
understanding?

Helmut
