I find that a wrapper is not necesary.  The most anoying thing from a  
C++ perspective is remembering to clean up after your surfaces.  With  
Boost's intrusive_ptr or shared_ptr this can be solved:

#include <SDL.h>
#include <boost/intrusive_ptr.hpp>

// We tell intrusive_ptr how to deal with SDL_Surface*
void intrusive_ptr_add_ref(SDL_Surface* p)

void intrusive_ptr_release(SDL_Surface* p)

void foo()
     // We pass false to the constructor because refcount==1 already.
     boost::intrusive_ptr<SDL_Surface> sfc(IMG_Load(file), false);
