From dfc946c20535ded2287ab03fb009cdbfb094af2b Mon Sep 17 00:00:00 2001
From: Stephen Torri <storri@users.sourceforge.net>
Date: Sun, 12 Dec 2004 03:04:58 +0000
Subject: Moved xv checks and tests to m4/xv.m4. Add --enable-shared-xv to
 force use of libXv.so over libXv.a. The default behavior is to use libXv.a if
 configure option is not used.
