20// stream templates to accommodate wide (and other?) kind of characters
21//
22// note the fact that on libraries without wide characters, ostream is
23// is not a specialization of basic_ostream which in fact is not defined
24// in such cases.   So we can't use basic_ostream<IStream::char_type> but rather
25// use two template parameters
