+dnl Look for the PIC library first, Debian requires it.
+dnl Check debian-devel archives for gory details.
+dnl 20020110:
+dnl At the moment XFree86 doesn't distribute shared libXv due
+dnl to unstable API.  On many platforms you CAN NOT link a shared
+dnl lib to a static non-PIC lib.  This is what the xvideo GStreamer
+dnl plug-in wants to do.  So Debian distributes a PIC compiled
+dnl version of the static lib for plug-ins to link to when it is
+dnl inappropriate to link the main application to libXv directly.
+dnl FIXME: add check if this platform can support linking to a
+dnl        non-PIC libXv, if not then don not use Xv.
+dnl FIXME: perhaps warn user if they have a shared libXv since
+dnl        this is an error until XFree86 starts shipping one
