Thanks for taking a look at the problem. IMO,
distributing objects between inlines and DLL functions
is not a very good idea. The classic example is:

//intended to be used as DLL.
class A
{
public:
  char* m_data;

  //compiled into application
  inline ~A()
  {
    if(m_data) delete[] m_data;
  }

  //calls DLL
  void init();
};

void A::init()
{
   m_data = new char[10];
}

IMHO, boost needs to get rid of any possibility of
this to happen.  Why does boost::signal() need a
DLL/LIB in the first place?  Would not be just the .h
file enough?
