>Description:

        libxine fails to recognise/decode video files encoded with xvid if
        compiled with gcc 3.4. The xine frontend will pop up an error dialog,
        saying video the format is not recognized, other frontends like
	kaffeine will just display no video and play audio-only.
        libxine compiled with gcc 3.3 or earlier will recognise and decode the
	video.

>How-To-Repeat:
        Compile libxine on 5-CURRENT with OSVERSION 502123 or higher (or
	6-CURRENT).
        Install a frontend (xine, kaffeine).
        Fetch http://people.freebsd.org/~lofi/test.avi and try to play it.
        Apply patch attached to this PR to the port, recompile libxine and try
	again.

>Fix:

        Force compilation of libxine with gcc 3.3, patch below. Again, this
	is more of a stop-gap than a real fix, but given that ports-freeze for
	5.3-RELEASE starts in less than a week, it's better than having a broken
	libxine distributed.

	Note that USE_GCC can NOT be used - it's ignored on recent 5.2-C, 5.3
	and 6.0 FreeBSD.
