Today gcc-7.3 arrived in sid, which seems to compile the kernel without
problems (see my previous post).
BTW, getting rid of gcc-8 was a bit of a pita, synaptic was no good for
that, had to do
# aptitude remove gcc-8-base
and follow the second suggestion, which fixed that issue here with a few
downgrades to the proper unstable versions. So please be careful what you
are doing in case you want to remove gcc-8.
