define "first" and "last".

directory iterators are single-pass input iterators, meaning that they  
represent no particular order.
if you iterate over the same directory 2 times, you might retrieve the  
entries in a different order.

you could e.g. copy the entries to a std::vector using std::copy and  
then sort them, choose first and last, etc.
