 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.
