+    <p>Generally, the iterator adaptors library can be compiled with all compilers
+    supporting iterator traits and type traits.</p>
+
+    <p>Microsoft VC++ is not able to handle iterator adaptors based on a 
+    <code>vector<T>::iterator</code> without specifying all template paramters explicitly.
+    In case not all template parameters are specified explicitly, the iterator adaptors
+    library will deduce these types using iterator_traits. But since in VC++ a
+    <code>vector<T>::iterator</code> is a <code>T*</code>, VC++ can't handle using 
+    iterator_traits due to the lack of partial template specialization.</p>
