xlint(1) patch

["Bill Marquette" <bill.marquette@xxxxxxxxx>]

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.
