From a21c3e353ad52ea34f76b908fa3382f656aa2449 Mon Sep 17 00:00:00 2001
From: "Thomas G. Lockhart" <lockhart@fourpalms.org>
Date: Thu, 9 Oct 1997 05:06:12 +0000
Subject: [PATCH] Allow 't', 'T', and even/odd ASCII characters to denote
true/false rather than just 't' and 'T'. This allows yes/no and 1/0 to be
interpreted as one might expect. Clean up function declarations to use bool
as the type for arguments and return values.
