reasons for this, quite a few of them technical, and not all of them
in response to Intel's broken ia32e crud.  The gcc toolchain stays at
x86_64 for now.

designed to output mdoc rather than shell script, and use them to produce
much better MAKEDEV.8 manual pages.
Note that MAKEDEV.man relies upon BSD m4 behaviour, which all m4 binaries
might not follow.

cron.  When ISC cron 5.0 is out the integration will be even tighter.
Also rename /var/cron/{allow,deny} -> /var/cron/cron.{allow,deny}
for consistency with POSIX and at.{allow,deny} and install an empty
cron.deny file (as we do at.deny) since crontab will require this
in the near future for POSIX compliance.
After a "make build" you can update your system as follows:
# mv /var/at/* /var/cron
# mv /var/cron/jobs /var/cron/atjobs
# mv /var/cron.allow /var/cron/cron.allow
# mv /var/cron.deny /var/cron/cron.deny
# rm -rf /var/at
# kill `cat /var/run/cron.pid` ; cron

There has not been enough activity and interest towards these platform
to keep them lying in the tree.

pval@ millert@ ok.

newsyslog.conf to reflect that.  More people seem to prefer that,
and it can be easily changed if you like it another way.
millert, fgs and others verbally agree

Job names are now "runtime.queue" where runtime is when the job will run
in Unix time format.  This is what SysV at does and allows us to nuke
the .SEQ file.
Historic BSD options for atq and atrm are now implemented;
atq and atrm get their own man pages.
At no longer does anything with the -v flag.  We print the execution
time when jobs are submitted so there is no need.
Most *scanf() usage is gone (one remains in atrun).
Better sanity checks in atrun.
Random style/cleanup.
With these changes we have the best of both worlds; POSIX compliance with
the traditional BSD features.

make -> ${MAKE}
add phony targets
remove unnecessary subshells
install kernel in a separate target from building.
some SUDO.
okay deraadt@
(checked bootstrap on i386, should be safe elsewhere, and trivial to fix
anyways)

make -> ${MAKE}
add exec at end of lines
sprinkle with SUDO where needed (not enough for a full release yet)
PHONY targets.
ok millert@, deraadt@

This means that /var/at/at.{allow,deny} must be readable by group
crontab, /var/at/jobs is mode 01770, and /var/at/.SEQ is mode 0660.

Use the -U flag instead of -u so mtree doesn't exit with non-zero
when fixing up existing permissions/owners.
