Date: Wed, 1 Mar 2006 23:52:09 +0100 From: Sam Hocevar Subject: [SDL] [patch] aalib driver Hi there. The attached patch fixes a buffer overflow in the aalib driver and also adds a workaround for a conflict between arrow keys and the numeric keypad that have the same scancode on aalib. The patch gives precedence to the arrow keys.
