I though more about a policy function/class. Something like:

   boost::dll my_dll("foo", cpp_mangler);
   boost::dll my_dll2("foo", c_mangler);

That's for sure. And in other contexts too.

Hmm... I've made the same remark in reply to Sven. The syntax is up for
discussion, though.

I also wonder if it makes sense to sumbit just "dll" library, or some
additional plugin support need to be developed first.
