This is probably the last change of such kind. There are many other
instances left, and fixing them all is hopeless. On the other hand,
the way mod 2^32 arithmetic works, although technically not always
well defined, is to our advantage. I suggest that only user-visible
discrepancies further be fixed.
The following comparison to st_size looks particularly bad.
The code turns out to be unused!
lib/signature.c:
> verifySizeSignature(const char * datafile, int_32 size, /*@out@*/ char * result)
> [...]
> if (size != st.st_size) {
> sprintf(result, "Header+Archive size mismatch.\n"
