Comment (by hvemha@…):

 I strongly advice against putting this kind of code into DllMain. You have
 no control over the order dll's are loaded and unloaded. E.g.
 `boost_thread-vc110-mt-gd-1_54.dll` might be unloaded before you receive
 `DLL_PROCESS_DETACH` in `BoostStudyDll.dll`

 The correct thing is to move the `DLL_PROCESS_ATTACH` code into your
 LoadBoostStudyDll function and the `DLL_PROCESS_DETACH` code into your
 FreeBoostStudyDll function.
