To clear this a bit:
At least all compilers I know of (gcc >=2.95 and msvc6 and above) only 
need to know the size of iVFS* at the declaration point (so here a struct 
iVFS; is enough). The Inc/DecRefs are resolved at the point when the 
destructor/constructor of the class is compiled. So in the .cpp file you 
have to include iutil/vfs.h.
If your compiler complains then you probably had the constructor and 
destructor implemented inline.
