With the STL containers, I didn't enable move operations in C++03 mode because that would change the overload resolution for things that today are copy operations. With iostreams, though, the copy operations aren't present at all, and so I see no problem with enabling move operations even in (Clang's greatly extended) C++03 mode. Clang's C++03 mode does not support delegating constructors. Differential Revision: https://reviews.llvm.org/D104310
