(which somehow now seems to be the default for compiling -current).
This error popped up while doing a PicoBSD cross-compile on a 4.3-ish system,
it may well be that there are other apps which have similar problems,
but I did not spot them as they are not included in my picobsd config.
Whether adding prototypes for main() is the correct solution or not
I have no idea, a request to -current on the matter went basically
unanswered. Those who have better ideas are welcome to back this out
and replace it with the correct fix.
We don't install dot.nsmbrc or smbfs.sh.sample, since we already install
the former as /etc/nsmb.conf and the latter is unnecessary, since
boot-time mounts can be arranged directly within /etc/fstab without fear
of breaking the boot when the smbfs port (now unnecessary is removed).

When a positively niced process requests a disk I/O, make
it wait for its nice value of ticks before scheduling its
I/O request if there are any other processes with I/O
requests in the disk queue. For all the gory details, see

commit by Kirk also fixed a softupdates bug that could easily be triggered
by server side NFS.
* An edge case with shared R+W mmap()'s and truncate whereby
the system would inappropriately clear the dirty bits on
still-dirty data. (applicable to all filesystems)
THIS FIX TEMPORARILY DISABLED PENDING FURTHER TESTING.
see vm/vm_page.c line 1641
* The straddle case for VM pages and buffer cache buffers when
truncating. (applicable to NFS client side)
* Possible SMP database corruption due to vm_pager_unmap_page()
not clearing the TLB for the other cpu's. (applicable to NFS
client side but could effect all filesystems). Note: not
considered serious since the corruption occurs beyond the file
EOF.
* When flusing a dirty buffer due to B_CACHE getting cleared,
we were accidently setting B_CACHE again (that is, bwrite() sets
B_CACHE), when we really want it to stay clear after the write
is complete. This resulted in a corrupt buffer. (applicable
to all filesystems but probably only triggered by NFS)
* We have to call vtruncbuf() when ftruncate()ing to remove
any buffer cache buffers. This is still tentitive, I may
be able to remove it due to the second bug fix. (applicable
to NFS client side)
* vnode_pager_setsize() race against nfs_vinvalbuf()... we have
to set n_size before calling nfs_vinvalbuf or the NFS code
may recursively vnode_pager_setsize() to the original value
before the truncate. This is what was causing the user mmap
bus faults in the nfs tester program. (applicable to NFS
client side)
* Fix to softupdates (see ufs/ffs/ffs_inode.c 1.73, commit made
by Kirk).

This only makes sense when "-w" option is also specified, because the
load is computed as the difference between subsequent samples.
I think this (and the "-d" feature which shows differences in the
network statistics counts) would also make sense in the standard
vmstat and netstat.
when taking a snapshot. The two time consuming operations are
scanning all the filesystem bitmaps to determine which blocks
are in use and scanning all the other snapshots so as to be able
to expunge their blocks from the view of the current snapshot.
The bitmap scanning is broken into two passes. Before suspending
the filesystem all bitmaps are scanned. After the suspension,
those bitmaps that changed after being scanned the first time
are rescanned. Typically there are few bitmaps that need to be
rescanned. The expunging of other snapshots is now done after
the suspension is released by observing that we can easily
identify any blocks that were allocated to them after the
suspension (they will be maked as `not needing to be copied'
in the just created snapshot). For all the gory details, see
the ``Running fsck in the Background'' paper in the Usenix
BSDCon 2002 Conference Proceedings, pages 55-64.
always deriving the credential for a newly accepted connection from
the listen socket. Previously, the selection of the credential
depended on the protocol: UNIX domain sockets would use the
connecting process's credential, and protocols supporting a creation
of the socket before the receiving end called accept() would use
the listening socket. After this change, it is always the listening
credential.

In original version grouping was hardcoded. It assumed that thousands
separator should be inserted to separate each 3 numbers. I.e. grouping
string "\003" was assumed for all cases. In correct case (per POSIX)
vfprintf should respect locale defined non-monetary (LC_NUMERIC
category) grouping sequence.
Also simplify thousands_sep handling.
