From a27b691e2903a886be640db801677f6f988d3793 Mon Sep 17 00:00:00 2001
From: Tom Lane <tgl@sss.pgh.pa.us>
Date: Sun, 3 Dec 2000 20:45:40 +0000
Subject: Ensure that all uses of <ctype.h> functions are applied to
 unsigned-char values, whether the local char type is signed or not.  This is
 necessary for portability.  Per discussion on pghackers around 9/16/00.
