    gio-du: Improve test program on Windows
    
    Make use of __wgetmainargs() on Windows so that we can get wide char
    versions of the argv's that are passed in when this test program is being
    invoked.  This is necessary as one might enter non-ASCII, such as
    CJK characters filenames and/or directories to run the test program
    against, so that we can process the name(s) and pass the proper
    UTF-8-encoded name(s) of the files/directories that is being tested.
