It doesn't need to. std::iterator_traits is partially specialized on pointer 
types, and otherwise tries to find the category as a nested type, which Qt3 
does provide unless QT_NO_STL is defined, and Qt4 provides unconditionally.

Got it from SGI's site. Might be an SGI extension, but is trivial to 
implement, of course.
