The latest CVS snapshot is available:
http://www.libsdl.org/cvs.html
This snapshot contains an initial port of SDL to QNX, written by Patrick
Trainor. This also includes an initial ALSA sound driver. The code sort
of limps along, so improvements are welcome! 
Oh, and the gamma ramp routines now have full 16-bit precision, as
requested by Daniel Vogel. For the most part, you can just take your
old values and shift them up 8 bits to get new correct values for your
gamma ramps. The SDL_SetGamma() API hasn’t changed.
See ya,
