Bob, 

Yes, it is my hope to do a test build this way and verify that things
work properly.   As far as I can tell the current tif_jpeg.c does not
repack the 16bit values returned by libjpeg6b (in 12bitmode) to 
12bit.   Folks have apparently used this form, but I don't really know
how they make it work. 

Best regards,
