State-Changed-From-To: open->closed
State-Changed-By: paolo
State-Changed-When: Wed Apr 16 19:07:14 2003
State-Changed-Why:
    The combination in|out|app is _illegal_ according to the ISO
    standard, closely followed by libstdc++-v3: see 27.8.1.3,2
    (or, f.i., Josuttis, p. 632)
    Thanks for your report, Paolo.
