Need to change uchar to char in a few places.
    In GCC 3.2, ostream is a typedef:
    typedef basic_ostream<char>  ostream;

    Since this template can only for char, it is invalid to do something like:
    uchar foo;
    ostream.write(foo);

    Changing uchar to char does not hurt things because:
    sizeof(char) == sizeof(uchar)

    but:

    typeof(char) != typeof(uchar)

    GCC 3.2 is much more fussy about enforcing types for templates
