It's a bit more complex than that. Boost.Coroutine depends on Boost.Context,
which is C++11. However, in order to not break C++03, Coroutine doesn't use
the public API of Context, but the private "fcontext" parts that are kept C++03
compatible only because of that. This incidentally means that if you compile
Context with the `ucontext` backend instead of the `fcontext` one,
Coroutine breaks.

So it's basically a mess and needs to be cleaned up. Since asio::spawn is a
separate part of Asio, moving just it to C++11 wouldn't be as disruptive a
change as requiring C++11 for all of Asio.
