thanks plenty!  I just did some builds for the QT6 release, but no one
at Apple mentioned this.  My bad for not staying on top of the devlist.
Oh well.

I don't mind a few patches, it helps to identify which changes correspond
to specific problems.  However, I would like to know if possible when you
think you've come to a stopping point so I can do a merge.

I'll be in Austria (MPEG) next week, not sure how much time I can devote,
but I hope to check your patches out before I go or on the plane, just to
get the process going.

Thanks again for all the work.
