	Searching the mjpeg-users mailinglist archive (put y4mdenoise into
	the search box) gives a number of results with "Compile error" in
	the subject.

	Here is the first one (which also lists some possible workarounds):

http://sourceforge.net/mailarchive/message.php?msg_id=eqj7om%24a15%241%40sea.gmane.org

	It's not a new problem.  Looks like it is a  g++ compiler bug.

	Cheers,
	Steven Schultz
