There is a difference between `state' and `global variables'.  For example,
the stdio library you mention, could keep its state in the (FILE *) object
you pass as its argument in the `no global variables' version of our
stdio library.  Functions which implement the `no (FILE *) argument'
version of the library routines would be simple wrappers ala

	printf (args ...)
	{
		return fprintf (stdio, args ...);
	}

where what you do to make "args ..." work is left to the reader ...
