Thanks again Jonathon. I guess this is what I don't quite
understand... From the preprocessor, GCC tells me the UINT64 type is
the following on x86_64:
#define __UINT64_TYPE__ long unsigned int
If 'long unsigned int' is the 64-bit integer and it meets alignment
and size requirements (as a 'minimum' of sorts), then why can't it be
used where the 64-bit type is required (i..e, the pointer in the call
to _rdrand64_step).
