On the Boost System page it is stated that:
The Boost System Library is part of the C++11 Standard Library.
But a number of Boost libraries, such as Asio, depend on Boost System. Is it possible to use the C++11 std stuff instead of Boost System to work with Asio?
AFAIR you can configure Boost System to be header-only

Other than that, you might simply use Non-Boost Asio
