hi there!

I'm using boost library occasionally and have this simpleton question to
ask.
i need to debug *boost::asio::io_service* by enabling
*BOOST_ASIO_ENABLE_HANDLER_TRACKING* macro.

so, do I have to rebuild the library like

*   ./b2 cxxflags="-DBOOST_ASIO_ENABLE_HANDLER_TRACKING"...*

or adding

*  #define BOOST_ASIO_ENABLE_HANDLER_TRACKING*

to my source file is enough? (this doesn't work for me, so i suspect I
should go with the first option)

thanks,
