It might matter, because there could be macros in standard libraries 
that conflict with those in the Boost libraries, although I'm sure Boost 
developers take pains to avoid this doing this.

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.
