This structure is not part of POSIX. According to POSIX, gettimeofday()
has the following prototype:
int gettimeofday(struct timeval *restrict tp, void *restrict tzp);
Also, POSIX states that gettimeofday() shall return 0 (as long as tzp is
not used). Remove dead error handling code. Also use NULL for a
nul-pointer instead of integer 0.
While there, change all pieces of code that only use tv_sec to use
time(3), as this provides less overhead.

- sort #include's and local variables;
- don't overuse initializers;
- use warn(3) instead of perror(3) consistently;
- amplify the comment on signals.
Add some constness to avoid some warnings.
Remove use register keyword.

commit and those which cause ugly nroff output have been fixed, since
the purpose of the style guideline which they contravene is to reduce

* Consistently misspell built-in as builtin.
* Add a builtin(1) manpage and create builtin(1) MLINKS for all shell
builtin commands for which no standalone utility exists. These MLINKS
replace those that were created for csh(1).
* Add appropriate xrefs for builtin(1) to the csh(1) and sh(1) manpages,
as well as to the manpages of standalone utilities which are supported
as shell builtin commands in at least one of the shells. In such
manpages, explain that similar functionality may be provided as a
shell builtin command.
* Improve sh(1)'s description of the cd builtin command. Csh(1) already
describes it adequately. Replace the cd(1) manpage with a builtin(1)
MLINKS link.
* Clean up some mdoc problems: use Xr instead of literal "foo(n)"; use
Ic instead of Xr for shell builtin commands.
* Undo English contractions.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;
.\" $Id$
.\"
If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

I've rewritten the patch as it was for 2.2.7. It can probably be put
into 3.1-STABLE as well.

instead.
Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.

Option "-f filename" will write to filename, and filename can be - to
write to stdout. Option "-a filename" will append the output to filename.
Time(1) man page has been updated to reflect the change.

shared memory size, average unshared data size, and average unshared
stack size were too high by a factor of 128/100, because the program
used a hard-coded hz value of 100. The correct value is the frequency
of the statistics clock, currently 128. The program now uses sysctl
to get the stathz value from the kernel.
