From b028e08d353f18d23c6b81d4ef260b1954adae72 Mon Sep 17 00:00:00 2001
From: Glenn L McGrath <bug1@ihug.co.nz>
Date: Fri, 13 Jul 2001 06:43:03 +0000
Subject: Move setvbuf calls from gz_open() to calling functions, setvbuf is
 only supposed to be called prior to opening the stream, glibc tolerates later
 use, uclibc doesnt.
