Using boost::chrono without linking to it

The boost::chrono documentation says

When BOOST_CHRONO_HEADER_ONLY is defined the lib is header-only.

Even with this defined, I'm getting linker error:

1>LINK : fatal error LNK1104: cannot open file 'libboost_system-vc100-mt-gd-1_48.lib'

Is this a documentation bug? Or does chrono really support header only usage?

The last version of Boost says " Boost.Chrono can be configured as a header-only library defining BOOST_CHRONO_HEADER_ONLY. However Boost.Chrono depends on the non header-only library Boost.System, so that you will need to link with boost_system.

Boost.System has un undocumented feature (use of macro BOOST_ERROR_CODE_HEADER_ONLY) to make it header only, but it is buggy (see #7347 duplicate symbol while BOOST_ERROR_CODE_HEADER_ONLY is defined) "

I think the bug has been fixed at least in trunk.
