Reiner, From my point of view tif_dir.h and tiffiop.h should still not be installed because the detail private interfaces. The dangers of depending on such private interfaces will become quite evident to any such users when they upgrade to libtiff 4 since there have been many internal changes. If PIL wants to use the G3/G4 code from libtiff I'd suggest instead that the code just be copied and adapted for the purpose. I've done this successfully for another g3/g4 format in my GDAL library.
