From 3f35fbbf668dab4c1a572f77a0912f4b7c8d857c Mon Sep 17 00:00:00 2001
From: Ian Romanick <idr@us.ibm.com>
Date: Thu, 17 Mar 2005 01:48:11 +0000
Subject: Fix the handling of zero-sized output parameters (i.e., those with
 type 'GLvoid *').  This fixes the GLX protocol for glGetProgramStringARB. 
 This fixes bugzilla #2747.

Remove the 'ignore="true"' from glVertexAttrib4bvARB.  This fixes bugzilla
#2746.
