Is there any way to tell, which version of the iterator library is
installed on a target system? I could think of some pp constant, which
allows to configure a piece of code to use the 'old' or the 'new'
iterator lib. This would allow for a smooth transition of existing
libraries depending on the iterator_lib and looses the otherwise tight
coupling between some user code and a specific Boost version.
