From c25294ad3ba1252a0d77bf63a27758a0eee4259e Mon Sep 17 00:00:00 2001
From: Paul Smith <psmith@gnu.org>
Date: Sun, 9 Apr 2006 22:09:24 +0000
Subject: Another round of cleanups: - Add more warnings. - Rename variables
 that mask out-scope vars with the same name. - Remove all casts of return
 values from xmalloc, xrealloc, and alloca. - Remove casts of the first
 argument to xrealloc. - Convert all bcopy/bzero/bcmp invocations to use
 memcp/memmove/memset/memcmp.
