 I pushed these already.  One seems to be an obvious fix
 for 32 bit platforms.  The other two are tidy-ups for the

The ULL-adding parts look fine.
The sscanf-improving part is probably fine, too

any parsing that I want to be robust, since it doesn't
detect overflow.  I.e., it will map an input of 2^64 to 0.
