I am getting an undefined label error. 
I know why. I do not know how to fix the problem:

	(Unix.fstat argument).st_kind

Here, the function returns a structure, st_kind
is a label of that structure, but it is not known
in the calling module. Is there a syntax for this?
Using 'open Unix' is unacceptable.
