Hi Simon,

Unfortunately 'unsigned long long' and 'uint64_t' are not necessarily compatible on 64-bit machines. Use the correct typedef instead of writing the supposed type out in full.
I doubt this statement.
I think "unsigned long long" always has 64bit width.
(C specification guarantees that the width of "unsigned long long" is greater or equal to 64 bit)
Could you tell me which toolchain violates it?
Some compilers use 'unsigned long' and some use 'unsigned long long'. I think that is the core of the problem.
We don't have a problem with unsigned long long not being at least 64-bit. I wonder whether some toolchains use 128-bit for this?
