Init style to quiet compiler.
Allow zcat hard link to compress rather than using zcat.sh wrapper; same as uncompress.
Don't install zcat, however; gzcat seems to be living in /usr/bin/zcat at the moment.
Add pckbc device, keyboard and mouse and wskbd and wsmouse via pckbc.
Init dev to quiet compiler.
Use u_int32_t rather than Sys-V u_long.
Rename err() to mtree_err(), to avoid conflict with libc.
Fix some whitespace lossage.
Cast args to strpct() u_long, as in the prototype, not ulong.
Add new option -S, which is like -s, but takes a string of options to pass to strip,
  rather than "-s". For example:
	install -S "-i -s symbolfile" foo /usr/bin/foo
  Invokes:
	/bin/sh -c "strip -i -s /usr/bin/foo"
  This is needed, because we need different strip options for dynamic libraries and
  Mach-O bundles than for executables; our strip supports more directed stripping.
  /bin/sh is used in this case, to parse the arguments.

Don't bother mmap()ing files of zero length. Was a workaround for a bug in our mmap(),
  which didn't get along with such files, but makes sense anyway.
Handle non-POSIX version of timespec.
umask()/mkdir() system calls will not set the setuid bit; the kernel intentionally
  discards the high bits, so "mkdir -m 1777 foo" won't set the sticky bit. So call
  chmod() on the directory.

Fix libc signal breakage (I hope).
Fix more syscall32 and signal breakage.
sync minor version number of libc
Copy "named-xfer" binary to "/usr/libexec" not to "/usr/sbin".
Fixes bin/6261 by Geoff C. Wing.
Eliminate memory leaks.
Use  xrealloc()  rather than  xmalloc/memcpy/free  trio.
print the strerror if swapctl fails.
Get rid of some lint.
No functional changes.
Oops, also needs "namespace.h".
One more piece of lint.
Eliminate all use of sprintf(3), and replace it with snprintf(3).
Bounds check the @exec and @unexec commands when they are constructed.
