Thanks.

Those are typedefs for std::bidirectional_iterator_tag. Hmmm. I tried to
worked around that by instead using

    typedef bidirectional_iterator_tag iterator_category;

in QValueListIterator and adding the following surrogates:

    struct input_iterator_tag {};
    struct forward_iterator_tag : public input_iterator_tag {};
    struct bidirectional_iterator_tag : public forward_iterator_tag {};

Got confusing error messages. Gave up. If somebody has a simple fix feel
free to submit it to qt-bugs.

Harri.
