The latest CVS snapshot is now available:

I have to get it in gear and release SDL 1.1.3! 
Thanks to Darrell Walisser and others, the latest CVS snapshot has full
MacOS support, including DrawSprocket and InputSprocket (for joysticks).
In addition, the command-line dialog only pops up if you hold down the
option key when you launch the game.
The DrawSprocket and InputSprocket code seems to work, but is not heavily
tested, so if you’re interested, take a look.
On the Linux side of things, the latest code now supports the unified
input interface in Linux 2.4 for joystick support. This means that if
you have input events compiled into your kernel and plug in anything
remotely resembling a joystick, SDL will be able to use it appropriately
with no configuration necessary.
The input code requires a bugfix to the Linux 2.4 kernel which hasn’t
been integrated yet, so look for it in the next kernel test release.
Enjoy!
