This is a problem common to both mingw and cygwin. They do not
support wide character I/O.
To overcome it, I tried installing STLport but your test case fails
to compile because the codecvt class is already defined in the _codecvt.h
STLport header. This is what I get:
$ g++ -I/usr/local/include/stlport stream2.cpp -o stream2 -liconv
-L/usr/local/lib -lstlport
stream2.cpp:20: error: expected template-name before '<' token

stream2.cpp:78: error: invalid use of undefined type `class

[tons of other errors]
Placing an "#if 0/#endif" around the codecvt class definition in
stream2.cpp doesn't work either:

-L/usr/local/lib -lstlport

Sigh.
