Comment 1 Thomas Deutschmann (RETIRED) gentoo-dev 2017-05-06 06:06:21 UTC 
Two options, either we apply a patch like https://build.opensuse.org/package/view_file/openSUSE:Factory/libfaketime/libfaketime-0.9.6-gcc6.patch or we set -Wno-nonnull-compare (see upstream's comment https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=811610#34).
