newtree/source/in_svgalib.c
Jeff Teunissen 50abe6080e Joystick support generalized, autoconfiscated. Systems without joystick 
support are built with joy_null.c. To create a joystick driver for a new
system, take a look at joystick.h and joy_null.c for the driver
interface. I'd like to see a Windows driver using this interface, it would
probably simplify in_win.c greatly.
