Please see revision [82351] on trunk. I'll appreciate it if someone using Clang with libstdc++ 4.2 tests it and reports whether it fixes the problem, or if not, what needs to be done.
A few comments: * `defined(BOOST_CLANG)` would be safer than `defined(__clang__)` after resolving #7359 ( https://svn.boost.org/trac/boost/ticket/7359 ); it seems that Intel compiler can define `__clang__`. * If you want to use std::nullptr_t on clang with libstdc++ newer than 4.2, you can use defined(__GLIBCXX__) && !(__GLIBCXX__ >= 20080306 && __GLIBCXX__ != 20080519) instead of `!defined( _LIBCPP_VERSION )`. I used this (ugly) version check to detect the availability of clang's type-traits intrinsics in boost/type_traits/intrinsics.hpp. But please note that when using with clang, Boost.Config does not recognize the correct version of libstdc++ (#7473 https://svn.boost.org/trac/boost/ticket/7473 ).
