FWIW, all three programs work on NetBSD/i386 -current too, none of them
works on NetBSD/sparc64 -current. The whole CMSG interface is a mess and
a very good example how to not design an API.

For an example how to get all the alignement and length fields right
look at mm_send_fd() in crypto/dist/ssh/monitor_fdpass.c in the NetBSD
source tree.
