  Added include: libkern/OSAtomic.h When building on macOS without gcc (e.g. clang) where HAVE_GCC_ATOMICS is not defined, `SDL_AtomicTryLock` will call `OSAtomicCompareAndSwap32Barrier` which is not yet declared. Including OSAtomic.h on OSX resolves this error/warning: SDL_spinlock.c:125:12: error: implicit declaration of function 'OSAtomicCompareAndSwap32Barrier' is invalid in C99 [-Werror,-Wimplicit-function-declaration] return OSAtomicCompareAndSwap32Barrier(0, 1, lock); This was reported in issue #3885 but marked Invalid and closed - possibly because the default CMake build uses gcc instead of clang.
