The __x86_64__ macro identifies a CPU family, and is unfortunately not enough to identify a concrete ABI. The normal x86_64 ABI that is used by practical Linux distributions is LP64 (i.e. 32-bit int, and 64-bit long and pointer), and defines __x86_64__ and __LP64__. x32 is a niche ILP32 ABI (i.e. 32-bit int, long and pointer) for x86_64 CPUs, which has different struct sizes due to sizeof(long) and sizeof(void *) being smaller. It defines __x86_64__ and __ILP32__. Signed-off-by: Simon McVittie <smcv@debian.org>
