FYI for the sensible people on this thread:

libstdc++ emits something via inline assembly with the above so that std::cin,
cout and cerr are properly initialised, just with the #include. I believe this
was necessary back in 2003 when the current version of libstdc++ was designed
or no one cleaned up at that opportunity. With the binary compatibility
requirements, it must continue doing that.

This violates "don't pay for what you don't need" and could be considered a
flaw in the current libstdc++ design. But it's not a bug and is not required by
the Standard, as evidenced by the fact that neither libc++ nor MS STL have
such shortcoming.

It's also easy to work around: #include a more precise header, like fstream,
strstream, ostream, etc.
