This is the case because boost assumes that a 4.2 compiler implies 4.2 libraries in flies such as boost/detail/atomic_count_gcc.hpp:

Yes, this is a bug or faulty assumption in boost.

The 4.2 library issue is a bug in Boost, not a problem with our compiler. I'd suggest raising the issue on one of the boost mailing lists and see what they say.
This is the first time I've seen a libstdc++ that's not in sync with the GCC version. Are there any preprocessor macros that identify the 4.0 libstdc++ vs. the 4.2 libstdc++? I don't know of any, but I guess we could just use __APPLE_CC__. - Doug
