The SDL_syswm.h header includes the windows.h header after including begin_code.h which changes the structure packing alignment.
It seems this is not safe as suggested by the following warning :
warning C4121: 'JOBOBJECT_IO_RATE_CONTROL_INFORMATION_NATIVE_V2': alignment of a member was sensitive to packing

Attached three patches, so these minor os/2 bits get registered mainstream:
1. SDL_syswm.h: add SDL_SYSWM_OS2 to SDL_SYSWM_TYPE enum
2. SDL_platform.h: recognize __EMX__ too as __OS2__
3. begin_code.h: set SDLCALL as _System for OS/2.
This only affects Wayland and DirectFB, as a Unix system generally has X11
support. Other platforms also have different sizes for the C union in
question, but are likely the only target for that platform, etc.
Apps that might run on Wayland or DirectFB will need to be compiled against
new headers from an official 2.0.6 release, or be prepared to force the x11
target, or not use SDL_GetWindowWMInfo().
Fixes Bugzilla #3428.

SDL2 allows to create widow and to get information through SDL_SysWMinfo.
But it misses something, with Vulkan, you need the HWND and HINSTANCE of the window for Win32 system.
Sadly, SDL2 provides only HWND but not HINSTANCE.
In some context, it can be difficult to get the HINSTANCE, indeed, I'm using pySDL2 (Python) and I can only access properties that SDL2 gives me.
I have to use a dirty trick like that to get the HINSTANCE: (https://raw.githubusercontent.com/bglgwyng/pyVulkan/master/examples/win32misc.py)
Note that extra steps must be taken when using glReadPixels to read the contents of the main OpenGL ES framebuffer on iOS, if multisampling is used. See the OpenGL ES section of README-ios.md for details.

using gcc 4.2 (the default) on Mac OSX 10.6.8
CC build/SDL_dynapi.lo
In file included from /Users/johnskaller/SDL/src/dynapi/SDL_dynapi.c:31:
include/SDL_syswm.h:211:39: error: missing binary operator before token "("
The fault appears to be here:
#if defined(__OBJC__) && __has_feature(objc_arc)
that the __has_feature macro is not supported by gcc 4.2.
The code works fine with my clang 3.3svn.
Based on the original port to Wayland by: Joel Teichroeb, Benjamin Franzke, Scott Moreau, et al.
Additional changes in this commit, done by me:
* Wayland uses the common EGL framework
* EGL can now create a desktop OpenGL context
* testgl2 loads GL functions dynamically, no need to link to libGL anymore
* Assorted fixes to the Wayland backend
Tested on the Weston Compositor (v1.0.5) that ships with Ubuntu 13.10,
running Weston under X. Tests ran: testrendercopyex (all backends), testgl2, testgles2,testintersections
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)
