#9472: ASIO library has link dependency, even though it claims to be header only
------------------------------+----------------------------
 Reporter:  soda@…            |      Owner:  chris_kohlhoff
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  asio
  Version:  Boost 1.55.0      |   Severity:  Problem
 Keywords:  header-only       |
------------------------------+----------------------------
 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:
