To enable the Debug Layer, set the hint, SDL_HINT_RENDER_DIRECT3D11_DEBUG to '1'.
The Debug Layer will be turned off by default, both in Release and Debug builds (of SDL).

I actually made a mistake when creating the previous patch file... I forgot to include a crucial line which changed.
I've attached a new patch which just changes the line I forgot, since the other part has already been applied to the repository.
I tested this one by doing a clean rebuild of SDL, and it works with the new patch.

Reopening as compilation with ANSI C throws lots of unnecessary warnings, both using MinGW and using Linux GCC. (BTW, what happened? MinGW is broken to all hell. sdl2-config does not even link SDLMain anymore?)
I think this may have been lost somewhere, so again: GCC supports inlining via __inline__ in all known versions of GCC, regardless of the C standard in use. Please don't assume that __STRICT_ANSI__ implies no inlining support.

I was going through the SDL_IntersectRectAndLine function and wondered to see the ComputeOutCode function implementation.
The problem in this algo is, x and y axis are getting check with respect to 0, Which is wrong, it should be get checked with respect to rectangle x and y axis.

The recommended way of getting a file name that POSIX file APIs can open in OS X when using an NSString is -[NSString fileSystemRepresentation]. However, the current filesystem API in hg uses -[NSString UTF8String].

Steps to reproduce: compile testjoystick.c as an android app (change screen size according to your device). While running the app, also run:
adb logcat -c; adb logcat -s 'SDL:*' 'SDL/APP:*'
When tilting the device left/right, the joystick moves in the opposite direction of what one would expect. Or at least, the behaviour is not consistent with the Y axis.
Also when the device sits on a table (obviously not moving), the Z axis value oscillates between -32000 and +32000 (by overflow):
I/SDL/APP ( 1994): Joystick 0 axis 2 value: 32511
I/SDL/APP ( 1994): Joystick 0 axis 2 value: 32575
I/SDL/APP ( 1994): Joystick 0 axis 2 value: 32383
I/SDL/APP ( 1994): Joystick 0 axis 2 value: -32386
I/SDL/APP ( 1994): Joystick 0 axis 2 value: -32450
I/SDL/APP ( 1994): Joystick 0 axis 2 value: -32578
This is caused by the accelerometer yielding a constant value around 9.81 for Z and feeding something like 0.9 to 1.1 to the joystick driver, resulting in the overflow.
Proposed fix in SDLActivity.java (swap X and subtract G from Z reading)

The problem in question is caused by changeset 7771 (http://hg.libsdl.org/SDL/rev/5486e579872e / https://bugzilla.libsdl.org/show_bug.cgi?id=2121)
The redefinition of __inline__ (introduced by the addition of begin_code.h:128's "|| __STRICT_ANSI__") results in mingw's gcc throwing multiple
warning: always_inline function might not be inlinable [-Wattributes]
as well as a whole bunch of redefinitions of mingw internals which break linking of projects including the SDL2 headers.
