because it only takes a struct tag which makes it impossible to
use unions, typedefs etc.
Define __offsetof() in <machine/ansi.h>
Define offsetof() in terms of __offsetof() in <stddef.h> and <sys/types.h>
Remove myriad of local offsetof() definitions.
Remove includes of <stddef.h> in kernel code.
NB: Kernelcode should *never* include from /usr/include !
Make <sys/queue.h> include <machine/ansi.h> to avoid polluting the API.
Deprecate <struct.h> with a warning. The warning turns into an error on
01-12-2000 and the file gets removed entirely on 01-01-2001.

to reinstall boot1 after a 'make world'.
Unfortunately this means that people who have already installed a new
boot1 from a 'make world' after 2000/09/18 *must* reinstall it after
their next build using something like:
# disklabel -B /dev/da0c
of IP datagram. This fixes the problem when firewall denied fragmented
packets whose last fragment was less than minimum protocol header size.

it can function before malloc(9) is up and running.
- Add two new options WITNESS_DDB and WITNESS_SKIPSPIN. If WITNESS_SKIPSPIN
is enabled, then spin mutexes are ignored by the WITNESS code. If
WITNESS_DDB is turned on and DDB is compiled into the kernel, then the
kernel will drop into DDB when either a lock hierarchy violation occurs
or mutexes are held when going to sleep.
- Add some new sysctls:
debug.witness_ddb is a read-write sysctl that corresponds to WITNESS_DDB.
The kernel option merely changes the default value to on at boot.
debug.witness_skipspin is a read-only sysctl that one can use to determine
if the kernel was compiled with WITNESS_SKIPSPIN.
- Wipe out the BSD/OS-specific lock order lists. We get to build our own
lists now as we add mutexes to the kernel.
getting libutil/libcrypt to work properly. I've determined that GCC
thinks it can inline all functions, including weak-symboled ones, if
it feels like it.
Create a new stub.c and move any stubs there to prevent inlining.
Thanks to jdp and William S. Duncanson for helping me finally find the
problem.
the PCI latency timer value to 0x80. Davicom's Linux driver does this,
and it drastically reduces the number of TX underruns in my tests. (Note:
this is done only for the Davicom chips. I'm not sure it's a good idea to
do it for all of them.)
Again, still waiting on confirmation before merging to stable.
