OK, with the docs there I can confirm it works fine for me, too. (I
thought I'd done all the right things, but obviously I missed something
out.)

(It ends up linking against libstdc++, whereas (IIRC, anyway) using
libcxxrt does not. So I'm not sure which I prefer. Likely it doesn't
make that much difference either way; primarily I want to be able to
build against another standard library (to try to catch errors), and
either build will work fine for that.)
