I'm sorry, but without seeing a short but releveant code example, one
    can only guess why.

The streams library shipped with 3.3 aims for compliance with the 1998
    ISO C++ standard. It is radically different from the 1990 ARM C++
    streams library 2.8.1 shipped with. If your code makes much use of
    custom stream buffers and such, you're in for some work.

Why are you instantiating a basic_ostream on char and NamedData? If
    NamedData is a traits class, it needs typedefs for pos_type,
    int_type, and off_type. If it isn't a traits class, it doesn't
    belong in basic_ostream's parameter list.

2.8.1 did not have a basic_ostream class template at all. So I don't
    think these errors are simply due to migration - something else
    must have been changed as well. (Possibly, you were using a
    3rd-party implementation of the standard library?)
