Comment (by anonymous):

 I just tried to compile `boost/units/detail/utility.hpp` with clang (trunk
 from monday) and no errors. I think the issue is not clang itself, but the
 C++ standard library used with it: I am using libstdc++ that came with gcc
 4.2.

 But using another standard library does not mean that
 `abi::__cxa_demangle` (the function used by utility.hpp) does not exist,
 as that function is not gcc-specific, but part of the C++ ABI:

 `__cxa_demangle` is defined in the header file cxxabi.h. Perhaps at build-
 time, bjam should check for the existence of this header file.
