It looks like some kind of installation or configuration problem, it
works fine here, on Debian/powerpc.

I looked into this, and mbstate_t is usually defined in wchar.h.  If
it's not, it should get defined in std_cwchar.h, just before your
error.  It looks like somehow, the #define's that guide this are
borked.

First, get this to compile:

    #include <iostream.h>
    int
    main ()
    {
            cout << "Hello world\n";
            return 0;
    }

You can just edit /usr/include/g++-v3/bits/std_cwchar.h, and add some
#error directives to see what's #define'd and what not.  Also
/usr/include/g++-v3/<arch>-<os>/bits/c++config.h might be worth
looking at.
