Is this documented somewhere?  I've seen ABI changes based on compiler
releases, but not based on whether or not the C++0x flag is set.  I'd
love to be as informed as you are on this.

Sure sounds like when someone changes a version of Boost, they end up
having to recompile the world both to avoid ODR violations and to make
sure things link correctly.  (Or course, if they have pieces of code
that don't use Boost those can remain unchanged.)
