rtcontrib bug

Hi All,

This morning, I found a bug in rtcontrib that causes it to sometimes fail writing out the last file when using the -b option, and can even result in a crash on some systems. The new version should be in tonight's HEAD dump, or you can grab it directly from CVS:

     http://www.radiance-online.org/cgi-bin/viewcvs.cgi/checkout/ray/src/util/rtcontrib.c?rev=HEAD&content-type=text/x-csrc

It doesn't depend on any other changes in HEAD, so you can drop it into src/util and run "rmake install" there if you've run "makeall install" previously.

This may be the cause of Francesco's mysterious problem using -f and -o together on the PC. I'm not sure about that, though.
