I have a mac pro running 7.1-PRERELEASE system (not sure when I last
updated it) on which burncd seems to successfully burn the data but
then fails while fixating.

I applied the above patch by hand, with a little bit of fuzz, and now
it fails to burn the data but fixating no longer bombs out.  Here's a
section of a script session (edited to remove the bulk of the written
lines...).

  fixating CD, please wait..

I think that I got the patch applied properly, I wonder if something's
changed to obsolete it?
