gcc 6.4.0, binutils 2.28.1 Since it is netsurf subproject - i suppose, other components also might have this issue.

I got working full-world workaround, affecting any ebuilds, where env compiler flags are working (might be some exceptions of course): In /etc/portage/bashrc: export CFLAGS="${CFLAGS} -Wno-error" export CXXFLAGS="${CXXFLAGS} -Wno-error"
Please always attach the complete build.log file, and attach/paste 'emerge --info'.
As of now, this package builds fine on a stable system, but "-Werror" is still part of CFLAGS and this makes building fragile. It's not all netsurf-related libs that add that flags, but some do (for example, libparserutils). It would probably be worth it to systematically add "-Wno-error" in dev-util/netsurf-buildsystem. Will look into it.
