8eaf7c78b9 Fixed bug #924 
Only use sysconf if _SC_NPROCESSORS_ONLN is available.  Fortunately the case for this was Mac OS X 10.4, which has sysctlbyname()

e989a1a23e Fixed crash - need to save and restore rbx around cpuid, since the compiler may be assuming the stack pointer isn't being modified when filling in %0. 
I did it around each call to cpuid which isn't strictly necessary, but is definitely future proof. :)

I am using x64 Linux (using Intel Core 2 DUO), and I have noticed that there is
an error in SDL_cpuinfo.c, function CPU_getCPUIDFeaturesExt for my platform.

Make sure every source file includes SDL_config.h, so the proper system

Subject: [SDL] Detecting Opteron CPU features

I can now get SDL_cpuinfo.c to detect the AMD Opteron's RDTSC, MMX, MMXEXT,
3DNOW, 3DNOWEXT, SSE, and SSE2 instruction set extensions under Linux.  It
took one #ifdef'ed block of new asm code to account for the 64-bit flags
register, but the other two blocks worked fine without modification, just
needed to modify the #ifdef's a bit.

From: Stephane Marchesin
Subject: Re: [SDL] 3DNow! detection on a P4 system

Well... I found another bug : 3dnow was detected on P2/P3 cpus. So I
took one more look at the code and found a mistake in
CPU_getCPUIDFeaturesExt :
The condition for having extended cpuinfo is that when we query extended
cpuinfo we get a result >=  0x80000001. So we must exit if eax < 0x80000001.
The attached patch does that.

From: Max Horn
Subject: SDL_HasAltiVec; BUGS file

the attached patch adds SDL_HasAltiVec to SDL CVS. Note that at this
point, this only works on MacOSX (and maybe darwin). I don't know how
to properly add a test for e.g. Linux/PPC at this point. I found an
email which might help in doing so:
http://zebra.fh-weingarten.de/~maxi/html/mplayer-dev-eng/2003-01msg00783.html
However, since I have no way to test on a non-OSX PowerPC system, I am
not comfortable blindly adding such code... I just hope that if
somebody from the Linux/PPC (or FreeBSD/PPC, or whatever) community
notices this, they'll jump up and provide a patch for us ;-)
