/*****************************************************************************
* 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>
