It's a feature of some Windows compilers that you can use "#pragma" to 
add linker instructions. How Boost uses/implements this is described in:

http://www.boost.org/more/getting_started.html#auto-link
Getting Started

And:

http://www.boost.org/libs/config/index.html#source

Specifically it mentions the boost/config/auto_link.hpp header.

I'm sure there's some VC docs on this also ;-)

HTH.
