Interesting.  Thanks for letting me know.  I'd love to know what the patch
that did it was.  I plan to diff sources after I make it through this
semester and get back up to 3.2-R levels.

Also, I've never supped CVS so I'm a little leary of doing that.  Is this
recommended for someone with a pixie-straw connection to the net (56k modem)?
Or just the fat pipe folks.
