[Boost-users] Running boost::thread compiled on w2k on XP

I have tried compiled boost::thread for windows using visual c++ from the 
visual studio .net 2003 suite. It compiles fine and I can compile things 
with the created libraries. However, when I move my program and the 
boost::thread dll:s from windows 2000 to another machine running windows XP, 
the program just prints out a blank line and exits without any other 
message. 

Attached is a program I have used to test out that it is this that is wrong. 
What have I done wrong? Is it impossible to compile the boost libraries on 
windows 2000 and then expect the created dll:s to work on windows XP? If 
this is the case, where can I get hold of the boost::thread libraries for 
vc71 compiled specifically for windows XP? If not, what could be wrong?
