    Investigating...

State-Changed-By: paolo
State-Changed-When: Sat Feb  8 21:27:56 2003
State-Changed-Why:
    Confirmed: upon a call of ios_base::sync_with_stdio(false)
    ios_base is currently fully _destroyed_ and then recreated
    in the new mode: meagre chances to keep intact the state ;)
    Let's what we can do...
