I fixed the problem by patching

boost/exception/enable_current_exception.hpp

=> inlined the templated function make_clone manually into the single
call location, which is in class clone_impl.

I'll attach the patch, don't know if it makes it through the list.

Also: the problem was not at all Boost.Signal related .. some other libs 
didn't build either.

Emil: thx for pointing me to the problematic file ..

tgo

ACK. Something weird is happening here ..
