I see the very same issue and reported this already. Since I'm not a
professional developer, I'm not quite sure what and how to report the
issue in exactly and accurate.

In my case, this issue came "out of the blue". I also have set

CXXFLAGS+=3D             -stdlib=3Dlibc++  -std=3Dc++11

but in /etc/src.conf. Commenting out "-std=3Dc++11" makes the build of
world fail with something like

[...]
fatal error: too many errors emitted, stopping now [-ferror-limit=3D]

[...]

which sounds strange to me, since I completely erase /usr/obj before
building and I do not use a ccache or any other similar facility.

Oliver
