Good point !

I probably did not make the argument well enough that even when you have 
Boost you might prefer the C++ standard equivalent to avoid the Boost 
dependency. In other words, "having Boost" and "depending on Boost", for 
a particular library, are conceptually two different things, at least in 
my mind.

Also the decision-making process in cxx_dual depends only on Boost 
Config. Other optional macro support in cxx_dual depends on PP and VMD. 
Tests depend on some other Boost libraries even when Boost is not chosen 
as a dual library. I can probably eleiminate the latter ( except for 
lightweight test ) if I want to.
