Comment (by Michel MORIN <mimomorin@…>):

 comment:1
 > `__cxa_demangle` is defined in the header file cxxabi.h. Perhaps at
 build-time, bjam should check for the existence of this header file.

 I made a new patch along this line (but the check is done at the compile-
 time,
 not at the build-time).
 Clang has `__has_include` macro that can detect a specified header file.
 So this check can be done at the compile-time when compiling with clang.

 I tested the patch on gcc 4.3-4.6 and clang TOT (with libstdc++ and
 libc++)
 in both C++03 and C++0x modes. `boost::units::detail::demangle` works fine
 on them.
