I don't believe so: remember that Boost.Config primarily exists to provide
workarounds for what Boost libraries are actually doing. In that context I
believe the macro to be set correctly - at least in the sense that library
authors haven't been complaining that the current settup breaks their stuff.

Ugh, please no. Is there a use case for this within Boost or is it an
arbitrary test case? My gut feeling is that folks that need to do "complex"
things can always use a BOOST_WORKAROUND instead?
