Since it's an internal array, you should be able to cast it to "unsigned
char *". Or, if you really want to keep broken out values instead of a
structure (why?), you could individually address each byte.
It might be helpful to have something like:
#define DATA4(d4) (((uint64_t)(d4)[0]<<56) \
((uint64_t)(d4)[1]<<48) \
((uint64_t)(d4)[2]<<40) \
((uint64_t)(d4)[3]<<32) \
((uint64_t)(d4)[4]<<24) \
((uint64_t)(d4)[5]<<16) \
((uint64_t)(d4)[6]<<8) \
((uint64_t)(d4)[7]))
so you can treat that last one as an integral quantity.
