Comment (by johnmaddock):

 This looks a lot like a clang bug to me, the code in
 type_traits/intrinsics.hpp sets the use of __is_abstract via:

 # if __has_feature(is_abstract)
 # define BOOST_IS_ABSTRACT(T) __is_abstract(T)
 # endif

 So... if clang __has_feature is indicating that __is_abstract is available
 what are we supposed to do?
