From e1765236c28b08b664c7f262533ca474adea39c9 Mon Sep 17 00:00:00 2001
From: Garrett Wollman <wollman@FreeBSD.org>
Date: Thu, 14 Sep 1995 16:25:06 +0000
Subject: [PATCH] Remove bogus (caddr_t) casts from FREE macros; they can
 obscure serious bugs that the type-checking would otherwise have found. 
 (This has no effect on anything that I noticed in the current system other
 than finding the bug in some code that I am writing.)
