12MY_CPU_LE means that CPU is LITTLE ENDIAN.
13MY_CPU_BE means that CPU is BIG ENDIAN.
14If MY_CPU_LE and MY_CPU_BE are not defined, we don't know about ENDIANNESS of platform.
15
16MY_CPU_LE_UNALIGN means that CPU is LITTLE ENDIAN and CPU supports unaligned memory accesses.
17
18MY_CPU_64BIT means that processor can work with 64-bit registers.
19 MY_CPU_64BIT can be used to select fast code branch
20 MY_CPU_64BIT doesn't mean that (sizeof(void *) == 8)
