It may not have been clear but when I wrote:

"The prints with %lld and a matching (long long) cast for the value likely
survive until long or int happens to be be bigger than 64 bits."

I was indicating that those changes are basically good and would likely survive
for a significant time.

A technical alternative for C code that is allowed to be modern enough is use
of (intmax_t) casts and j based formats for printf variants.

(Similarly for local intmax_t storage and j formats for scan variants, where
the intmax_t value is later range validated and conditionally converted into
the intended storage if the value fits.)

I have no clue how old of a C variant iozone's source code intends to support.
intmax_t might be too modern for simple direct use over iozone's intended C
vintage range, at least viewed for source also spanning outside a FreeBSD
context.
