xlint(1) patch

[Bill Marquette]

Not sure if this got missed, or if someone was waiting on something
else.  lint doesn't work at all right now w/out this patch.  Also at
http://www.pfsense.org/~billm/dfly/xlint.patch

Looks like lint won't run with gcc 3 w/out some tweaks.  Here's a
patch that allows lint to run (noisily) against itself, stolen from
OpenBSD; probably it ought to be sync'd again from NetBSD where it
came from, this at least allows it to "do something" again.
