Sigh... no, while that would no doubt fix a few tests, what users were 
asking for (and what we now build by default) is a single binary for 
gcc/*nix systems that can be used irrespective of whether they're using 
threads or not.  In other words we want to fix the Boost ABI to be the same 
as the libstdc++ ABI, no matter whether a default threading-single build is 
done or not.

Hope this is making some sense, but I don't know what the correct solution 
is....
