Should I write (for example):
#include <iostream> #include <boost/test/unit_test.hpp>
or
#include <boost/test/unit_test.hpp> #include <iostream>
Or does it not matter?
It might matter, because there could be macros in standard libraries

I always go by the principle that older definitions should take precedence over newer ones and so put standard libraries before Boost libraries (the opposite of what has been advised by David Abrahams) and then include own header files after that. As Boost developers are nod oubt careful not to redefine anything in standard libraries, I suppose the order doesn't make any difference. Those more familiar with the way compilers work might be able to say whether or not this is the case. Paul
