Attached is a patch (it works for me[TM]) which adds a CheckLinuxVersion() to
configure.in and a check for HAVE_LINUX_VERSION_H to
src/cdrom/linux/SDL_syscdrom.c.

Subject: Re: [PATCH] *CRITICAL* 8bit direct RGB palette not being created
I think that SDL_AllocFormat should create the palette for all 8bit
surfaces. And when the RGBAmasks match the normal 3:3:2:0 we need to
apply the old behavior. If the mask doesn't match that, then we need
to make the right palette assuming the masks are valid (I don't think
we validate any masks for high color surfaces...so we wouldn't here)
Then there's always a palette available for the 8bit surfaces.
This restores the normal behavior and allows for masks to create
palettes automatically for odd masks even, which would be a neato
thing to have in there, as SDL never did this before.

OS report these are "horizontal scrollwheel" events, which confuses gaming
apps in several legitimate conditions. Now all scrollwheel events are made
to look vertical when passed to the app.

Subject: [SDL] Diffs for dsp audio in case of failures.
The rewrite recently done for 1.2.8 forgot to handle error cases
by closing the audio.
Here is a patch that does.

I noticed that on my ia64 machine when SDL_Quit was called, the machine would
hang in weird ways. It turned out to be caused by a machine check in the
memset() call near the top of FB_VideoQuit. Generally memset shouldn't be
used on I/O regions like the framebuffer or other I/O device memory (the
Linux kernel has special routines for dealing with I/O memory), so I changed
the #ifdef __powerpc__ to #if defined(__powerpc__) || defined(__ia64__) and
SDL_Quit now works properly. The change should probably be made
unconditional though since doing one byte at a time is the only way to be
portable, afaik.

Subject: RISC OS SDL Patches
Sam, I've attached a diff of the latest changes to libSDL for RISC OS
support. These changes are by Alan Buckley and myself.
The most significant of these are:
Optimised assembler blit rountines - I've attached the file
src/video/riscos/SDL_riscosASM.s which is needed for this.
Move to using /dev/dsp instead of its own audio implementation.
This means that src/audio/riscos/SDL_drenderer.c should be removed
Typo fixes. Mainly correct spelling of "RISC OS", but some from elsewhere
too.

Subject: Patch to put back dynamic OpenGL loading for MPW
I sent a patch a while ago that removes dynamic OpenGL loading for
Macintosh Programmer's Workshop. Dynamic loading DOES actually work
when an SDL program is built with MPW, it just has to be set up for it.
(Whoops!!) This is the ideal way to get OpenGL extensions to work,
which D2X uses quite a few of.
This patch puts dynamic loading back in SDL for Mac OS 9. It applies to
current CVS. I noticed that two members need to be set when
DrawSprocket is used.

Subject: [SDL] minor bugfix for test/testoverlay2.c
Programs that use malloc ought to #include <stdlib.h> . On 32-bit systems you
can get away with not including it, but on 64-bit systems it will assume
malloc() returns a 32-bit integer and butcher the 64-bit pointers it returns.

Subject: [PATCH] SDL/DirectFB: remove Matrox CRTC2 flicker filter
Hi,
This patch removes the flicker filter option from the DirectFB backend's
Matrox CRTC2 code in SDL. I will be removing the option from DirectFB
(because it doesn't actually work) and that would cause the SDL code to
fail without this fix.
I was going to send this to some SDL list directly but libsdl.org is down
so I'm not sure what if any lists there are. Thomas Jarosch (the guy who
wrote the code) said you would accept SDL patches. Let me know if I should
send this somewhere else.

Subject: [SDL] KeyRepeat fix
If you switch keys very fast and hold the last one it
doesn't get repeated because the key release of the first key
occured after the key press of the second key.
Unfortunatly the key release of the first key sets
SDL_KeyRepeat.timestamp = 0; causing the the second key not to repeat.
This should be always reproducable. I've only checked this on x86-64
X11.
To fix this I just added another condition to make sure the sym of the
released key matches SDL_KeyRepeat.key.keysym.sym.
