Subject: Dynamic loading of ALSA
I recently discovered that SDL can dynamically load ESD and aRts, and
made a patch which adds this same functionality to ALSA.
The update for configure.in isn't too good (it should e.g. look for
libasound.so in other directories than /usr/lib), because I'm not too
good at shellscripting and autoconf.
The reason for using dlfcn.h and dlopen instead of SDL_LoadLibrary and
SDL_LoadFunction is that libasound uses versioned symbols, and it is
necessary to load the correct version using dlvsym. This isn't probably
any real portability issue, because ALSA is linux-only.

Subject: Problems compiling libsdl with gcc 3.3
I attached another patch (configure.in.patch) that might resolv issues
for some ppl finding the correct place of libartsc.so.*.
(here, the output of "artsc-config --libs" contains two "-L.*",
therefore the respecting arts_lib_spec contains the wrong path).

Subject: SDL/QNX6 new patch
Here in attachment my patch for the SDL/QNX6 again :) It contain non-crtitical/cosmetic fixes:
1. Fixed window centering at other than the first consoles.
2. Fixed window centering algorithm in case when window height or width are greater than the desktop resolution.
3. Fixed window positioning on other than the first consoles.
4. Fixed occasional input focus lost when switching to fullscreen.
5. Removed the Photon's default chroma color for the overlays, added RGB(12, 6, 12) color instead (very dark pink).
6. Added more checks to the YUV overlay code (fixed crashes during resolution mode switches).
7. Added support for Enter/Backspace keys in unicode mode (used by Maelstrom and by other games).
8. Fixed window restore/maximize function. It works, finally.

Subject: SDL configure.in patch
On my cygwin compile environment, I get a script error with configure.
$ ./configure --enable-debug=no -q;
appending configuration tag "CXX" to libtool
appending configuration tag "F77" to libtool
./configure: line 28135: : command not found
*snip the rest*
The supplied patch fixes the problem, just a minor oversight of some [ ] & t\

Subject: [SDL] Two little patches
Compiling SDL with a recent gcc (gcc 3.3.1, 3.3 doesn't have this
behaviour) gives some nasty warnings :
SDL_blit_A.c: In function `BlitRGBtoRGBSurfaceAlpha128MMX':
SDL_blit_A.c:223: warning: integer constant is too large for "long" type
SDL_blit_A.c:225: warning: integer constant is too large for "long" type
SDL_blit_A.c:227: warning: integer constant is too large for "long" type
[...]
The first attached patch (longlongfix.patch) tells gcc to really treat
those constants as unsigned long long and not long.
The second patch (nasinclude.patch) fixes an include problem I had while
compiling nas audio : when the <audio/audiolib.h> file lies in
/usr/X11R6/include, a -I/usr/X11R6/include option is needed or the file
isn't found.

Subject: Package building for QNX6
I'm just completed the package description file for QNX6 - qpg, it is like a\
.spec files for Linux. Please place SDL.qpg.in file in the root of the proj\
ect, where .spec file is placed. And sdl12qpg.diff - just adding the SDL.qpg\
.in. The same for the SDL_image. I'm planning to add .qpg files creation for\
all SDL* projects.
As for shared library building for QNX6. It is very hard to improve the exis\
ting libtool code to support QNX shared libraries. Much easyiest is to remov\
e libtool.m4 code from the acinclude.m4 for those persons, who building shar\
ed libraries for QNX6. I'm described all what they need to do with .so under\
QNX6 in the README.QNX file. And 90% of people used the precompiled librari\
es, so I think it is not big problem :)

Subject: SDL/QNX forgotten fixes
Just found, that one chunk for configure.in has not been applied and one for\
gotten by me :) Please add it to CVS.
P.S. Now QNX6.2.1 have the dlopen in libc and in the libltdl. So libc's vari\
ant more prefered, and ltdl rest for compatibility. In this small patch I wa\
s added proper checks.

Subject: New patches for QNX6
Here my patches for the SDL/QNX:
QNXSDL.diff - diff to non-QNX related sources:
- updated BUGS file, I think QNX6 is now will be officially supported
- configure.in - added shared library support for QNX, and removed dependency between the ALSA and QNX6.
- SDL_audio.c - added QNX NTO sound bootstrap insted of ALSA's.
- SDL_sysaudio.h - the same.
- SDL_nto_audio.c - the same.
- SDL_video.c - right now, QNX doesn't offer any method to obtain pointers to the OpenGL functions by function name, so they must be hardcoded in library, otherwise OpenGL will not be supported.
- testsprite.c - fixed: do not draw vertical red line if we are in non-double-buffered mode.
sdlqnxph.tar.gz - archive of the ./src/video/photon/* . Too many changes in code to make diffs :) :
+ Added stub for support hide/unhide window event
+ Added full YUV overlays support.
+ Added window maximize support.
+ Added mouse wheel events.
+ Added support for some specific key codes in Unicode mode (like ESC).
+ Added more checks to the all memory allocation code.
+ Added SDL_DOUBLEBUF support in all fullscreen modes.
+ Added fallback to window mode, if desired fullscreen mode is not supported.
+ Added stub support for the GL_LoadLibrary and GL_GetProcAddress functions.
+ Added resizable window support without caption.
! Fixed bug in the Ph_EV_EXPOSE event handler, when rectangles to update is 0 and when width or height of the rectangle is 0.
! Fixed bug in the event handler code. Events has not been passed to the window widget handler.
! Fixed codes for Win keys (Super/Hyper/Menu).
! Fixed memory leak, when deallocation palette.
! Fixed palette emulation code bugs.
! Fixed fullscreen and hwsurface handling.
! Fixed CLOSE button bug. First event was passed to the handler, but second terminated the application. Now all events passed to the application correctly.
- Removed all printfs in code, now SDL_SetError used instead of them.
- Disabled ToggleFullScreen function.
README.QNX - updated README.QNX file. Added much more issues.
