I did more tests:
- emerge sys-devel/gcc:13 fails with the same error
- after installing gcc:13 binpkg and activating it in eselect gcc, emerge sys-devel/gcc:14 fails with the same error.

I don't know if it's important or not, but I'm using kernel v6.10 from github/torvalds and linux-headers v6.9 from portage. I couldn't find a guide how to install headers from an external kernel source. Running make headers_install in the kernel source dir made a mess in /usr/include.
