SDL 2.x recently accepted patches to enable OpenGL ES 2 support via Google's ANGLE library. The thought is to try to eventually merge SDL/WinRT's OpenGL code with SDL-official's.
Haiku uses most of the standard pthread API, with a few #ifdefs where we
still need to fallback onto the old BeOS APIs.
BeOS, however, does not support pthreads (or maybe doesn't support it well),
so I'm unplugging support for the platform with this changeset. Be Inc went
out of business in 2001.
This bumps the build SDK level to 12 (up from 10). Runtime requirements remain
the same (at API level < 12 joystick support is disabled).
Also enables building SDL for armv7 and x86.
A port of the ANGLE library (OpenGL ES 2.0 for Direct3D) to WinRT, via https://github.com/stammen/angleproject, is used as a base.
To enable, clone 'angleproject' into the directory one above where SDL/WinRT is, open the file SDL/include/SDL_config_winrt.h, and uncomment the #defines that begin with 'SDL_VIDEO_OPENGL'. From there, apps can create an OpenGL capable SDL_Window via the flag, SDL_WINDOW_OPENGL, and an OpenGL ES 2 context via SDL_GL_CreateContext. The Direct3D 11.1 renderer cannot be used alongside SDL_WINDOW_OPENGL. Only Windows 8/8.1 is supported for now. Shaders may need to be precompiled, in some (all?) cases.
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).

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.

The problem in question is caused by changeset 7771 (http://hg.libsdl.org/SDL/rev/4434498bf4b9 / 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.

Fixes the version check for some functions that are only present with the MSVC 2013 CRT libraries.
I did my testing wrong and failed to see that 2012 doesn't have these functions. Microsoft implemented them in their upcoming 2013 version, though. The attached patch changes it to the check for the next version.
I also removed the HAVE_ITOA because that would require linking with oldnames.lib and it's easier to just let the SDL implementation take over.
This is part of an overall effort to use the name, "WinRT", rather than "WindowsRT" (or "Windows RT"), as the shorthand name often seems to mean something different than the longhand name. (WinRT is an API, Windows RT is a product name)
We needed a bit, so we're hoping no one needs this effect, especially when
it's fairly close to SDL_HAPTIC_SINE, we hope.
SDL_HAPTIC_LEFTRIGHT maps to XInput's functionality, so this removes the SINE
code for the XInput driver to keep things clean.
This also makes the simplified Rumble API use SDL_HAPTIC_LEFTRIGHT if
SDL_HAPTIC_SINE isn't available, to keep XInput working.
When we break the ABI, and can extend the supported capabilities field from
a Uint16, we'll add SDL_HAPTIC_SQUARE back in.
This patch is based on work by Ethan Lee.
q66
after updating SDL2 to the latest RC I'm unable to build my game engine under mingw crosscompiling environment for Windows (32bit, hosted on freebsd 64bit).
The error is in SDL_thread.h with messages like this: http://codepad.org/jEQXd3Yq
The problem is, while _beginthreadex return type is correctly mapped to uintptr_t (as specified by Microsoft), the return type under mingw is unsigned long int (same size, different signature), resulting in the error above.
The reason it didn't error before is this: http://codepad.org/8FAbKAxz
You can see the _beginthreadex case is only used without HAVE_LIBC defined; at one point though, SDL_config_windows.h was changed like this:
-/* Enabled for SDL 1.2 (binary compatibility) */
-#define HAVE_LIBC 1
+/* This is disabled by default to avoid C runtime dependencies and manifest requirements */
resulting in these errors.
