Include arm_neon.h in mingw targeting ARM Windows.
The llvm-mingw project includes cross-compilers targeting ARM: https://github.com/mstorsjo/llvm-mingw/releases
Currently, compilation fails with this configuration, because neon features are used as long as __ARM_NEON is defined, but arm_neon.h was not included.

Windows: NEON detection and intrinsic includes on Visual Studio
Visual Studio doesn't define __ARM_ARCH nor _ARM_NEON, but _M_ARM and _M_ARM64,
so SDL_HasNEON() was bypassed.
PF_ARM_NEON_INSTRUCTIONS_AVAILABLE doesn't see to be defined (but still works
when defined as 19).

(Visual Studio needs a different fix).

Fixed bug 4392 - SDL_cpuinfo.h breaks compilation with C bool type
Luke Dashjr
Bug 3993 was "fixed" by #undef'ing bool. But this breaks C99's stdbool.h bool too.
For example, mpv's build fails with:
../audio/out/ao_sdl.c:35:5: error: unknown type name ?bool?
It seems ill-advised to be #undef'ing *anything* here - what if the code including SDL_cpuinfo.h actually wants to use altivec?

Fixed bug 4103 - SDL_cpuinfo.h provokes warnings with -Wundef on non-x86 hosts
Felix Geyer
Forwarding from https://bugs.debian.org/892087 quoting verbatim:
The SDL2 header SDL_cpuinfo.h generates gcc warnings if the program using
it compiles with the -Wundef warning. (In particular, this means that QEMU
builds using it fail on at least sparc hosts, since QEMU dev builds
use both -Wundef and -Werror.).
/usr/include/SDL2/SDL_cpuinfo.h:63:5: warning: "HAVE_IMMINTRIN_H" is not defined, evaluates to 0 [-Wundef]
#if HAVE_IMMINTRIN_H && !defined(SDL_DISABLE_IMMINTRIN_H)

Fixed bug 3993 - altivec.h include in SDL_cpuinfo.h breaks compilation with -std=c++11
bastien.bouclet
According to this GCC bug report, altivec.h requires building with the gnu extensions: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=78263.
As an application developer, I don't want SDL to force me to enable the gnu extensions.

Fixed crash if initialization of EGL failed but was tried again later.
The internal function SDL_EGL_LoadLibrary() did not delete and remove a mostly
uninitialized data structure if loading the library first failed. A later try to
use EGL then skipped initialization and assumed it was previously successful
because the data structure now already existed. This led to at least one crash
in the internal function SDL_EGL_ChooseConfig() because a NULL pointer was
dereferenced to make a call to eglBindAPI().

the last parameter of XChangeProperty is the number of elements.. and when the element format is 32.. the element is "long" so we have 5 long elements here.
Yes this seems confusing as on mac+linux Long is either 32 or 64bits depending on the architecture, but this is how the X11 protocol is defined. Thus 5 is the correct value for the nelts here. Not 5 or 10 depending on the architecture.

Fixed bug 2802 - [patch] Fix android build compiling in wrong filesystem implementation
Jonas Kulla
The configure script didn't differentiate between Linux and Android, unconditionally compiling in the unix implementation of SDL_sysfilesystem.c.
I'm probably one of the very few people building SDL for android using classic configure + standalone toolchain, so this has gone undetected all along.

WinRT: fixed bug whereby SDL would override an app's default orientation
WinRT apps can set a default, preferred orientation via a .appxmanifest file.
SDL was overriding this on app startup, and making the app use all possible
orientations (landscape and portrait).

[X11] Reconcile logical keyboard state with physical state on FocusIn
since the window system doesn't do it for us like other platforms.
This prevents sticky keys and missed keys when going in and out
of focus, for example Alt would appear to stick if switching away
from an SDL app with Alt-Tab and had to be pressed again.

Fixed bug 2376 - no SDL_HasAVX
Haneef Mubarak
AVX is the successor to SSE* and is fairly widely available. As such, it really ought to be detectable.
This functionality ought to be trivial to implement, and not having it means being forced to write an ugly workaround to check for AVX (so that normal SSE can be used if AVX is not available).
Here is an example on detecting AVX from SO (it actually shows ways to cehck for all of teh fancy instructions):

Fixes #2022, do not resume on Android when surfaceChanged
If the app is in landscape mode and the user presses the power button, a pause
is followed immediately by a surfaceChanged event because the lock screen
is shown in portrait mode. This triggers a "false" resume.
So, we just pause and resume following the onWindowFocusChanged events.
Also, wait for SDL_APP_WILLENTERBACKGROUND and SDL_APP_DIDENTERBACKGROUND before
blocking the event pump.
