reverse conversion (const to non const) is invalid and disallowed.

This compares an iterator for equality with an integer.

It is totally type unsafe and I don't know why std::_Ptrit

provides it. Maybe for comparison to NULL?..no, that doesn't

make sense, you should only compare iterators with other iterators,

including the return value of Container::end().
