>Description:
operator!() const does not seem to call fail(), as mandated
by the ISO C++ standard, 27.4.4.3. This code fragment:
fstream afile(MYNAME, ios::in|ios::out|ios::app);
assert(afile);
always leads to an assertion, even when the stream could be
opened correctly. Looks as if fail() is not called at all,
at least operator!() always seems to return false.
