Problem linking boost::threads using MSVC6 SP4

I've created a windows console project with VC++ 6.0 and just used 
one of the examples in the documentation. I've also added the 
BOOST_HAS_THREADS macro in the settings. The program compiles well in 
debug mode but gives the following linking errors:

Any help on this would be appreciated.
