+ *     This is obviously useful for initialized globals (which cannot be extern or similar).
+ *     This is also used in the log mecanism where a macro creates the variable automatically.
+ *      When the macro is called from within SimGrid, the symbol must be exported, but when called 
+ *      from within the client code, it must not try to retrieve the symbol from the DLL since it's not in there.
