I dont think that is the problem because he is linking with  
libboost_unit_test_framework-vc80-mt-1_35.lib, and since there is no 
'-s' in the name, it links with MSVCRT, and it is selected by boost 
autolink when you use option /MD and and you are not compiling DEBUG code.

Plus, it works flawlessly on my system.

I _did_ notice a difference between our liker options; You don't have 
the subsystem set. When I throw together an msvc project I get this 
linker option:

/SUBSYTEM:CONSOLE

If I remove that option, I get:

1>LINK : fatal error LNK1561: entry point must be defined

Personally, I never even paid attention to it before (the defaults 
always worked for me), but I guess that is probably your problem.

open your project properties, and change Linker->System->SubSystem from 
[Not Set] to '/SUBSYSTEM:CONSOLE', or just manually add it to the 
command line and see if that works.
