	This routine is needed in order to reconstruct a FileSpec that has been
	exported and now needs to be imported and formed into a valid object.
	
	Since the object doesn't exist, we don't have its vtbl and since we
	don't have its vtbl, we can't tell it to create itself.  So this forms
	the glue that allows this to happen.
