shared_ptr only uses typeid(T), where T is a type, so it works on some 
compilers with RTTI off. But not on GCC. You need to replace the bodies of 
the two functions with 'return 0;' to make it compile. Of course you 
wouldn't be able to use get_deleter with this modification, but everything 
else should work.
