Use <iosfwd> instead, I think <ostream> introduces a static initializer.

Done.

When I patched your CL locally, the clang compiler complained that this struct
does not have a destructor.

I think it complained about a couple of other structs not having constructors
and destructors

No warnings on Windows. I added some ctors/dtors. I hope I fixed all the cases.
