Apparently the "-x objective-c" made it down to the linker, who then treats
the .o file as Objective-C source code. Apparently the -ObjC argument does
the same thing but gets ignored by the linker.
Fixes Bugzilla #4988.

This small patch fixes the KMSDRM_CreateSurfaces() call in KMSDRM_CreateWindow(), that was segfaulting deeper into SDL internals because the windata->viddata pointer wasn't set before the KMSDRM_CreateSurfaces() call.
So that's what this small patch does.
Now, L?VE2D works perfectly well on the Raspberry Pi 3, instead of just segfaulting.

I just tripped over this: stb_image when requesting 3 channels with 8-bit actually returns them as 3 bytes per pixel with no alignment, so basically 4 pixels are 12 bytes with no padding (0...2, 3...5, 6...8, and 9...11). This I would have naively expected to be called RGB888 or BGR888, since there is no "dead" unused byte as I would expect for something called e.g. RGBX8888.
However, SDL2's SDL_PIXELFORMAT_BGR888 uses 4 bytes, same as SDL_PIXELFORMAT_BGRX8888, even though the latter appears to be a longer storage format - which it isn't, internally. It's just swapped, in byte order X, B, G, R (instead of BGRX). So why isn't the macro name also swapped, as "XBGR888" instead of just "BGR888"?
I find the formats therefore named inconsistently, and unless there is a reason for this I suggest these changes:
1. deprecate SDL_PIXELFORMAT_BGR888 in favor of a new SDL_PIXELFORMAT_XBGR8888
and
2. deprecate SDL_PIXELFORMAT_RGB888 in favor of a new SDL_PIXELFORMAT_XRGB8888

but no longer exists in Windows 10 SDK 10.0.19041.0.
After searching this macro in the sdk include path, I found that it was defined in many header files. But it should be replaced in windows.system.h .
On some systems, GetClipCursor() impacts performance when called frequently, so only call it every once in a while to make sure we haven't lost our capture.

I'm trying to build SDL2 with threads support here in GNU/Linux, both X86 and ARM, and it does not seem to be possible ATM:
/home/manuel/src/SDLLLL/src/core/linux/SDL_threadprio.c:233:26: error: 'rtkit_max_realtime_priority' undeclared (first use in this function)
