Note that you'll have to do that to "struct rpc_msg" as well - which
means getting that structure from tcpdump header files rather than from
native OS header files. (I just tried running, on a SPARC/Solaris
machine, the latest tcpdump, reading a Token Ring capture; it got an
alignment fault on
direction = (enum msg_type)ntohl(rp->rm_direction);
in "print-udp.c".)
I don't know if there are any other structures left that we're getting
from the OS; we should be defining most, if not all, of them ourselves
now.
