Description Sylvain 2018-12-03 08:51:32 UTC 
(at least) on Android ndk-r18:

if you compile with arm64-v8a, __ARM_NEON__ isn't defined (so SDL2 doesn't include "<arm_neon.h>"), but __ARM_NEON is.

on arm-v7a, if you enable neon with Android.mk, both get defined.

Seems that __ARM_NEON__ is legacy and we should use __ARM_NEON
