There's a new JPEG_DUAL_MODE_8_12 define, but it is only mentioned in the tif_config.h and NOT in the other platform specific versions like:

       tif_config.h-vms tif_config.vc.h tif_config.wince.h

It would be nice if it was alse mentioned in those files as well.

So this brings up a second issue. Is the code for this define safe to enable when compiling libtiff for general purpose usage? What are its requirements? Is libjpeg6b enough?

See http://trac.osgeo.org/gdal/wiki/TIFF12BitJPEG for a description of what this is.

Libjpeg 7 is out now, but there are not yet similar patches for it.
