Clean up malloc(3)'s argument. Remove casts which do nothing when we're
using sizeof() anyway. Use slightly more consistent (per-file) error
reporting for malloc(3) returning NULL. If "malloc failed" was being printed,
don't use err(3). If a NULL format is being used, use err(3). In one case
errx(3) was being used with strerror(3), so just use err(3).

remove __P

Warns cleanups. Add missing prototype.

Fix typo: compatability -> compatibility.

Compatability is not an existing english word.

$Id$ -> $FreeBSD$

Clean up some ambiguous nested if/elses.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

Close PR#1455. In a couple of weeks, I'll change bsd.lib.mk to use
tsort -q as well - I don't feel like adding tsort as Yet Another Item to the
bootstrap target.
