There's a lot of classes/functions that io classes depends on. My 
current goal is to implement cout in msvcp90, in order to do it I need 
to add support for locales first (there's still around 40 classes to 
implement before it's done).

You can start implementing functions that don't depend on missing 
functionality, but I think it's better to implement the functionality it 
depends on first.

Streams behaviour may be affected by msvcrt related settings. If so you 
will need to use msvcrt io functions. It should be quite easy to check 
by e.g. locking stdout in msvcrt and trying to write to it using c++ 
functions.
