Unfortunately, there's no default constructor available for ostream in VC++.

In VC++ for basic_ofstream they do what Alex initially did and pass a
pointer to a member variable in.
Having trawled through the VC++ and gcc std lib source code a bit more,
I think this might be the better solution (sorry Warren). Mainly
because in the _Uninitialised::_NoInit constructor in VC++ it calls
ios_base::_Addstd(this) whereas, unless you specify a second param of
true, in the other constructor it doesn't. Unfortunately, I have no
idea what _Addstd does, except that it's "special handling for standard
streams". Also, taking this approach it's the same across platforms,
even if it does rely on all implementations doing nothing with the
pointer you pass in, except for storing it.
