+/*****************************************************************************
+ *  Defines the native methods used for windows to extract some system information.
+ *  <p>
+ *  This class will need some native code from the library proxy_util_"arch".dll.
+ *  To load this library we use a three step algorithm as following:
+ *  </p><P>  
+ *  First check the System property "proxy_vole_lib_dir" if it is set and 
+ *  it points to a folder where the dll is found than the dll from this 
+ *  folder is loaded as e.g. <i>"proxy_vole_lib_dir"/proxy_util_w32.dll</i>
+ *  </p><p>
+ *  Second we try to load the dll from the subfolder <i>lib</i> if that one exists.<br> 
+ *  Finally if we are inside of a jar file we need to extract the dll file
+ *  to a temp-file because windows can not load dlls from a jar 
+ *  directly. This is a hack but it may work.
+ *  </p><p>
+ *  Please note that the file is named Win32ProxyUtils but has now also support
+ *  for x64 architecture.
+ *  </p>
