SHChangeNotify()

[Francois Gouget]

shlwapi.spec exports SHChangeNotify. However I see no implementation of 
this function in shlwapi. There is an SHChangeNotifyWrap() function 
however. Weirder still, SHChangeNotifyWrap() does not seem to be called 
anywhere, is not exported by shlwapi.spec, and calls SHChangeNotify().

So I'm confused as to how this is supposed to work. Could you clarify 
things for me?
