size_t can be wider than unsigned long.  On modern Windows, for example,
unsigned long is 32 bits and size_t is 64 bits.

strtoull could also work (and as far as I know there are no current
implementations with uintmax_t wider than unsigned long long), but
strtoumax (which I misspelled above) makes the point more clearly.
