Actually thats 8 on alpha.
And if you pack that to 5 the program will run with 10% speed and
generate a lot of unaligned traps. DON'T do that. Write a parser that
can read the data from file in a arch independant manner.

If you don't you will get a critical bug as soon as you release the
package, because if won't work on different endianess, even if you
pack the struct.

May the Source be with you.
