9472,Undocumented define causes header-only libraries to have link dependency on system,soda@…,Beman Dawes,"Code using the ASIO library must be linked with a boost binary lib, even though asio is considered 'header only' library.

Test system - ubuntu 13.10, using boost 1.55 download archive (not installed package).

Similar problem reported in ticket 7085.  Suspect this is systemic.

Demo source code:
