+ * 
+ * Rational of XBT_PUBLIC: 
+ *   * If you build the DLL you must pass the right value of XBT_PUBLIC in the project : to do this you must define the DLL_EXPORT macro
+ *   * If you do a static compilation, you must define the macro DLL_STATIC
+ *   * If you link your code against the DLL, this file defines the macro to '__declspec(dllimport)' for you
+ *   * If you compile under unix, this file defines the macro to 'extern', even if it's not mandatory with modern compilers
+ * 
+ * Rational of XBT_PUBLIC_NO_IMPORT:
+ *   * This is for symbols which must be exported in the DLL, but not imported from it. 
+ *     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.
