levels by which they are used. On a typical production setting (no
debug or filter logging) this will save an open/read/close system
call sequence per packet, approximately halving the system overhead
and reducing the overall overhead by 38%.

is mostly mechanical except for the replacement of a couple of snprintf()
and sprintf() calls with strlcpy.
Skinny is the protocol used by Cisco IP phones to talk to Cisco Call
Managers. With this code, one can use a Cisco IP phone behind a FreeBSD
NAT gateway.
Currently, having the Call Manager behind the NAT gateway is not supported.
More information on enabling Skinny support in libalias, natd, and ppp
can be found in those applications' manpages.

fixed in gcc-3.3 (waiting for after the branch), and the hack will be
backed out at the first opportunity. This is in the ipv6 code path.

time_t. Deal with the possibility that time_t != int32_t. This boils
down to this sort of thing:
- time(&ut.ut_time);
+ ut.ut_time = time(NULL);
and similar for ctime(3) etc. I've kept it minimal for the stuff
that may need to be portable (or 3rd party code), but used Matt's time32
stuff for cases where that isn't as much of a concern.

o <machine/ansi.h> will continue to live so it can define MD clock
macros, which are only MD because of gratuitous differences between
architectures.
o Change all headers to make use of this. This mainly involves
changing:
#ifdef _BSD_FOO_T_
typedef _BSD_FOO_T_ foo_t;
#undef _BSD_FOO_T_
#endif
to:
#ifndef _FOO_T_DECLARED
typedef __foo_t foo_t;
#define _FOO_T_DECLARED
#endif
