From 4e9676fb13f60ecdbc247b120031f18cd3febcb0 Mon Sep 17 00:00:00 2001
From: Brian Paul <brian.paul@tungstengraphics.com>
Date: Sat, 29 Jun 2002 19:48:15 +0000
Subject: Applied Matt Sealey's patch to remove/isolate all stdio.h function
 calls. Instead of mstdio.[ch], use imports.[ch] to isolate these functions.
