The 32-bit buildfarm animals don't like this too much [1]:
astreamer_verify.c: In function 'member_verify_checksum':
astreamer_verify.c:297:68: error: format '%zu' expects argument of type
'size_t', but argument 6 has type 'uint64' {aka 'long long unsigned int'}
[-Werror=format=]
297 | "file \\"%s\\" in \\"%s\\" should contain %zu bytes, but read

298 | m->pathname, mystreamer->archive_name,
299 | m->size, mystreamer->checksum_bytes);

| uint64 {aka long long unsigned int}
Now, manifest_file.size is in fact a size_t, so %zu is the correct
format spec for it. But astreamer_verify.checksum_bytes is declared
uint64. This leads me to question whether size_t was the correct
choice for manifest_file.size. If it is, is it OK to use size_t
for checksum_bytes as well? If not, your best bet is likely
to write %lld and add an explicit cast to long long, as we do in
dozens of other places. I see that these messages are intended to be
translatable, so INT64_FORMAT is not usable here.
Aside from that, I'm unimpressed with expending a five-line comment
at line 376 to justify casting control_file_bytes to int, when you
could similarly cast it to long long, avoiding the need to justify
something that's not even in tune with project style.
