This is bad news indeed! The one problem I found is probably related to 
a Borland bug which, if I remember correctly, causes a class's 
destructor to be instantiated where it shouldn't. The net result is that 
  scoped_ptr (and auto_ptr) cannot be used to implement the pimpl idiom. 
I managed to build the signals libraries by replacing shared_ptr for 
scoped_ptr in named_slot_map.hpp, but I didn't have time to run any 
test. I have no idea whether this may be an acceptable fix or if there's 
any other outstanding problem.

Hope this helps, anyway.

Cheers,
