/bin/dd/args.c
static uintmax_t get_num(const char *val)

type SIZE_T would be more appropriate as a return value,
because size_t could include largest size of any object.

uintmax_t on the other hand may be one of extended integer types(if
implemented, for example, 128bit number on x64), so exists possibility, tha=
t no
object could have that much size,
so its more than needed, size_t would serve better in this case.

Indeed, analogous function that does the same
static size_t get_bsz(char *val)
in OpenBSD's dd has return type size_t;
