I think it depends on how clang is built and Boost.Build is not relevant here.

In my setting, clang uses libstdc++ of gcc-4.2 which does not support C++0x.
IIRC, clang does not support newer versions of libstdc++.
So, to use the C++0x's standard library, you need
libc++ (http://libcxx.llvm.org/).
Clang uses libc++ if you pass "-stdlib=libc++" to the compiler.

FYI, the code (with modification of `boost::is_enum` to `std::is_enum`)
compiles fine with clang and libc++.
