Trying to finally package 4.3.0 for Gentoo (sorry for the delay, stuck ~2000km away from the lab due to Corona), I run into this:

Any advice is appreciatied... Kernel 5.4.33-gentoo, gcc 9.2.0, more info on request.

Found it, this is commit 1868.

With that backported things build fine. New release maybe?

[DaveP]

Thanks Andreas. I'll ask Frank whether I can go ahead now to cut a new
release.
cheers,
