Subject: [SDL] [PATCH] sdl-config.in needs ${libdir}
Hello,
after the patch for Bug #321, sdl-config.in needs the libdir variable. and
there is a hardcoded 'lib' in SDL.spec.in too.

Subject: [SDL] SDL_config_macosx.h: MAC_OS_X_VERSION_MIN_REQUIRED
Hi,
I just compiled my SDL application on Mac OS X with -Wundef and it
threw a number of errors. Of note was:
SDL_config_macosx.h: 34
warning: "MAC_OS_X_VERSION_MIN_REQUIRED" is not defined
Line 34 is:
#if ( (MAC_OS_X_VERSION_MIN_REQUIRED >= 1030) || (!defined (__POWERPC__)) )
Now according to this mailing on the Apple developer lists:
http://lists.apple.com/archives/Xcode-users/2005/May/msg00602.html
that particular #define was removed from the gcc compiler defaults
and AvailabilityMacros.h (/usr/include/AvailabilityMacros.h) should
be pulled in directly instead.
Would someone closer to the Mac OS X version of SDL be willing to
make that change please? Thanks.

since a memory page's size may vary on various architectures and kernel
configurations.
Will use getpagesize() if it exists, the PAGE_SIZE #define from older kernels
if that doesn't, and #error out if that's not there either...but it's
probably 4096 in that case. We may revisit this.

to distinguish this...the keys being replaced would be correct on a USB

Subject: [SDL] Alpha blending bug - fixed?
It turns out mm5 never got the correct value. This failed :
[...]
"movd %1, %%mm5\n\t"
: : "m" (amask), "m" (sf->Ashift) );
mm5 got 0xFF000018 instead of 0x00000018. However I did this :
Uint32 ashift = sf->Ashift;
[...]
"movd %1, %%mm5\n\t"
: : "m" (amask), "m" (ashift) );
and everything worked fine.
The only thing I could find out was that ashift is 32-bit aligned but
sf->Ashift isn't:
printf("ashift %8X [%d]\n", &ashift, (int)(&ashift) % 4);
printf("sf->Ashift %8X [%d]\n", &sf->Ashift, (int)(&sf->Ashift) % 4);
ashift at BFF0E0C4 [0]
sf->Ashift at 08AFB9CD [1]
Could this be the problem? If it is, the fix is extremely trivial.
Should I submit a patch?
