The bug is not in VC10 per se, but in the specification of decltype. An
issue has been raised with the standardization committee and proposed
wording has been suggested. Hopefully, it'll make it into C++0x Final.

What that means for Boost.Config is unclear to me. We may decide to
define a defect macro for this particular buggy decltype behavior, since
gcc's decltytpe works this way, too.
