From 1fa0981836eb33dd37061c4f2965525c513e3ca6 Mon Sep 17 00:00:00 2001
From: Ezra Peisach <epeisach@mit.edu>
Date: Fri, 1 Jan 2010 16:41:04 +0000
Subject: [PATCH] Change db_args from being a global to only defined in the
 function that uses it. This removes a warning of shadowed variable names. 
 Change several functions to static when limited to main.c
