Boost.Exceptions is a library on Win32. It builds 
"libs/exception/src/clone_current_exception_msvc.cpp"

which states at the top:

#if defined(_MSC_VER) && defined(_M_IX86) && !defined(_M_X64)

so this is for x86 only. On x64, no code gets compiled.

The msvc linker then "helpfully" silently omits the creation of an empty dll 
and the corresponding copy step(s) fail(s).

The correct fix would be to build this file only on for the <address-model>32 
case but I don't know if this can be specified with the current Boost.Build.

Yours,

Jürgen
