SDL_ltoa(-2147483648,s,10) only returns "-" because there is a bug in the code:
if ( value < 0 ) {
*bufp++ = '-';
value = -value;
}
but -(-2147483648) is still -2147483648 (0x80000000) as signed int (or long), so the following loop doesn't run at all. Similar bug are also in SDL_lltoa.
BTW, there is no sanity check for radix.
SDL_GameControllerAddMappingsFromFile is now a convenience macro.
controllermap can now skip bindings by pressing space or clicking/touching the
screen.

As described in the other thread
(http://lists.libsdl.org/pipermail/sdl-libsdl.org/2013-November/091997.html),
I've run into a case of SDL2 not recognizing a wireless Xbox 360
controller receiver properly on Debian Linux amd64 testing.
Apparently, the generated GUID is slightly different.
Device in question:
Bus 001 Device 015: ID 045e:0291 Microsoft Corp. Xbox 360 Wireless
Receiver for Windows

Steps to reproduce:
1. Grab the cursor with SDL_SetCursorGrab()
2. Alt-tab away from the window
3. Click on the titlebar of the window
This will cause the window to disappear underneath the taskbar!
This appears to be a general issue with ClipCursor() on windows, i.e. I am getting the same behavior if I call ClipCursor() directly.
It is caused by a feedback loop between the ClipCursor function and the modal resize/move event loop that handles mouse-based sizing on Windows.

The SDL_ceil function is implemented incorrectly when HAVE_CEIL is not defined (HAVE_LIBC not defined).
The following code:
double val = SDL_ceil(2.3);
printf("%g", val);
prints "2.0", as STD_ceil is defined as:
double
SDL_ceil(double x)
{
#ifdef HAVE_CEIL
return ceil(x);
#else
return (double)(int)((x)+0.5);
#endif /* HAVE_CEIL */
}
This functions is used in the SDL_BuildAudioResampleCVT function of the audio subsystem (SDL_audiocvt.c), and causes a bug in that function.
Lets Android take care of which is the primary pointer (the one acting as the
mouse in SDL), reorganized the Java side code as well to make it easier to
understand.

To keep the directory layout sane, we should probably move this one piece of source to the linux catch-all directory, instead of making it look like this is part of an SDL "input" subsystem.

The MMX path in SDL_fillrect.c uses the SSE intrinsic _mm_stream_pi. The function or symbol provided by the compiler will not be present because the SSE header may not get included. The linker will complain about an undefined reference.
Since this is the only intrinsic used here (and someone forgot to create one for MOVQ), I think the MMX path can be removed completely. At least I don't see another way to move 64-bits from an MMX register to memory.

On OS/X after calling SDL_SetWindowBordered right mouse clicks no longer register.
Steps to Reproduce:
1. Open a windowed window on OS/X. (With the border on.)
2. e.button.button will give values 1,2,3 depending on which mouse button I click.
3. Call SDL_SetWindowBordered to disable the border.
4. e.button.button will only give values 1,2. 3 (right mouse button) stops coming through.
Expected result:
I expect all mouse buttons to register.
