It was OK until gcc 4.7.
As gcc 4.7 is much more strict the build of the code doesn't work any more.

I suspect boost itself as no (active) functions
//      void intrusive_ptr_add_ref(T * p);
//      void intrusive_ptr_release(T * p);
In boost_1_49_0/boost/smart_ptr/intrusive_ptr.hpp

Searching the internet shows that more programs have this issue. It's not unique for scummvm-tools, they solved it, for the time being, with ""-fpermissive"" which IMHO isn't the correct way.
