The push_options.hpp and pop_options.hpp headers are used in matched pairs. In this case, one pair for the whole file, and one for the non-asio headers. </p> <p> The reason for wrapping the non-asio headers is now mostly historical I think. Some headers supplied by Borland compilers would change alignment options and not restore them. </p> Ticket
