Off hand: every syscall that takes a time_t or a structure containing a time_t would have to be reimplemented and a compatability version provided in the old location. The same would be true of every similar function in the libc symbol map. A number of ioctl's and sysctl would probably need to grow compatability interfaces as well. -- Brooks --PEIAKu/WMn1b1Hv9 Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (FreeBSD) iD8DBQFI0CI+XY6L6fI4GtQRAiCgAKDRrCB/zMXZnax/OXKR/g979hrUIwCgmo7y MdQtWAMGVKUqyiOaUBmmM5I= =LXp3 -----END PGP SIGNATURE----- --PEIAKu/WMn1b1Hv9--
