       7: **  TREE -- create new tree node.

       9: **	This is a stripped down version of the same thing in the
      10: **	parser.
      11: **
      12: **	It only knows about lengths of zero and two.
      13: **
      14: **	Parameters:
      15: **		lptr -- the left pointer.
      16: **		rptr -- the right pointer.
      17: **		typ -- the node type.
      18: **		len -- the node length.
      19: **		value -- the node value.
      20: **
      21: **	Returns:
      22: **		A pointer to the created node.
      23: **
      24: **	Side Effects:
      25: **		Space is taken from Qbuf.
