Subject: Fix to compile SDL-1.2 SVN on OS X Leopard

I found I needed to add a conditional check for Leopard to compile
cleanly on 1.2-SVN (20071114):

#include <AudioUnit/AudioUnit.h>
#ifdef AVAILABLE_MAC_OS_X_VERSION_10_5_AND_LATER
#include <AudioUnit/AUNTComponent.h>
#endif

where there is now just:
#include <AudioUnit/AudioUnit.h>
