SDL_ExitProcess(), SDL_AbortAssertion() and SDLTest_BailOut().
(Commit 303c1e0fb0cf for bug #4100 removed SDL_NORETURN from
SDL_ExitProcess() and SDL_AbortAssertion() in order to avoid
warnings from windows builds, but that's temporary I guess..)

http://hg.libsdl.org/SDL/rev/d702b0c54e52 resulted in an error and
two warnings when compiled with mingw.
1. Error from SDL_windowstaskdialog.h:
In file included from src/video/windows/SDL_windowsmessagebox.c:29:0:
src/video/windows/SDL_windowstaskdialog.h:23:54: error: expected ')' before 'HWND'
This is fixed by removing unnecessary annotations:
2. Warning from SDL_assert.c:
src/SDL_assert.c: In function 'SDL_ExitProcess':
src/SDL_assert.c:138:1: warning: 'noreturn' function does return
Indeed ExitProcess() is prototyped with DECLSPEC_NORETURN, but
TerminateProcess() is not. This can be rectified by adding an
exit() call in there. Do NOTE, however, that requires building
with a libc:
3. Warning from SDL_windowsmessagebox.c:
src/video/windows/SDL_windowsmessagebox.c: In function 'WIN_ShowMessageBox':
src/video/windows/SDL_windowsmessagebox.c:513:9: warning: 'nCancelButton' may be used uninitialized in this function
My lazy solution was manually initializing nCancelButton to 0.
"What I have done is use TerminateProcess rather than ExitProcess.
ExitProcess will cause Microsoft's leak detection to continue, TerminateProcess
won't. It is also technically wrong to use ExitProcess in the case of aborting
the application.

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().
