We probably knew this, but on an x86, I get:

Sizeof(char) = 1
Sizeof(short) = 2
Sizeof(int) = 4
Sizeof(long) = 4
Sizeof(long long) = 8

Given all this, I would suggest changing all longs to ints.

However, I have seen some embedded 68k systems that use Sizeof(char) = 4.

They could be changed to u_int or to __u32. I would prefer the former, but the latter would be more certain. 16-bit compilers thought Sizeof(int) = 2, but I really doubt we will ever see one of those...

Understood. The parts that I am concerned about are *print?() statements that will want %ld or %Ld to differentiate between 'long' and 'long long' on x86. From the 'man 3 printf' I gather that <no options> imply 'int'

Do you need help?

Perhaps these should have used 'u_int iv[2]' or even '__u64 iv[1]'.

Yup.
