when using boost::interprocess under win32, i ran into the following  
problem:
in boost/interprocess/detail/win32_api.hpp several static inline  
functions have a function local class
for releasing resources, like 'unlink_file', which defines 2 classes:
handle_closer, and auto_ptr

due to a compiler bug, as discussed here: http://www.eggheadcafe.com/conversation.aspx?messageid=32706692&threadid=32706692

you get a LNK2005 error  <symbol> already defined in <object>

when using boost::interprocess from multiple .cpp files

a solution is to use boost::shared_ptr instead of local classes in  
win32_api.hpp, like this:

   boost::shared_ptr<void> hiPSAPI =  
boost::shared_ptr<void>(load_library("PSAPI.DLL"), free_library);

attached is the complete patch
