i dont think afa os has anything to do with it, except it is the same person that did "aros on amiga" and the sdl.library port. why would that be? bernds sdl needs his ixemul library instead, thats right, even though as far as i see the effort by artur and novacoder is to replace this dependance by another statically linked library that proviudes both rtg and native amiga chipset support at the same time for sdl applications.
im not quite sure how far this is by now.
