Hi,
I wish to close PR 9982. This PR suggests that IPv4 address is not
unsigned int and fix it to 32bit long. So, I took in_addr_t changes
from OpenBSD and made a patch.
It may break binary compatibility on Alpha, where u_long is 64 bits
but in_addr_t would still be 32 bits.
It seems working well on my *Pentium* box. However, I have no 64 bits
environment.
Please review the changes.
