build: fix FTBFS on GCC 6.2

I'm not surprised that GCC 6 doesn't let me send an ostream ref to itself,
even inside an uninstantiated template specialization.  I am a little
surprised I was trying to, and 4.9 let me get away with it.

It's 2016.  auto_ptr is deprecated now.

Some things were including vector that don't any more.
