	The following patch fixes two bugs in the bid function of GB5.2.

  o Checks to see if the bid and shipping costs exceed your current funds.
	(before it only checked for the bid > money not (bid + ship) > money)

  o Checks to see if you have outstanding bids and deducts that amount from
    your available funds.  (to prevent a player from bidding on all the lots
    when he only has the money to pay for some of them)

	I highly suggest installing this patch, as the latter of the two bugs 
	can cause core dumps.
