No, if you choose to build Boost::foo as static and it happens to be 
used by at least two different consumers (at least one of which is 
shared) that end up as part of a single final application, that's 
exactly the problem case that I was talking about.

This is because that can end up with multiple copies of the library in 
the same application (but in separate binaries), subject to the whims of 
the platform and linker.
