Yes, thanks, now I see it is about instantiation. I can write 
map_it->second.push_back( ... ) without error. But:
cmdMap.emplace( std::pair< Unit*, CommandList > ( ait->pUnit, 
CommandList( ) ) );

gets me the same error:
C:\cpp\boost_1_42_0\boost/intrusive/list.hpp(1478) : error C2248: 
'boost::intrusive::list_impl<Config>::list_impl' : cannot access private 
member declared in class 'boost::intrusive::list_impl<Config>' ...

I'll see about doing this the smart pointer way.

Best, Dan.
