There's also a patch to adapt one test for the nds, and that adds several
makefiles to compile these tests. Whenever you apply it, could you completely
remove the test/nds-test-progs/sprite and test/nds-test-progs/sprite2
directories ?

I've cleaned up a few bugs in the nds code. A few more tests now pass.
There's still a few things to do, but overall I think it's starting to be in a
good shape.

The patch also includes a bug fix for SDL_ConvertSurfaceFormat() (gcc warning).

Implemented thread priority as the 'nice' value on Linux.  High priority threads require root permissions (you shouldn't give your game root permissions though!)

rename : test/testhread.c => test/testthread.c

Something inside setStyleMask mucks with the view responder chain, which prevents the listener from hearing the right mouse down events.  We just reset the listener after changing the style to fix this.

Fixed issue when calling SDL_BlitScaled() directly with src or dst rectangles that were out of bounds.

If application installs SIGINT/SIGTERM signal handler with
sigaction(SA_SIGINFO) syscall before initializing SDL, after
initialization
of SDL signal handler will be reinstalled without SA_SIGINFO flag which
brings havoc when the signal handler is called. The breakage is done by
SDL_QuitInit()/SDL_QuitQuit() function. They use signal() to detect that
signal handler is already installed even in sigaction() is available.

the attached patch brings the DirectFB driver back in line with recent
SDL 1.3 developments.
