There is a difference in output between Ghostscript 8.71 and head (r11492) that
is likely related to the icc_work changes.  When converting the file
altona_visual_1v2a_x3.pdf (which can be found in tests_private/compare_files)
the number 28 element is rendered differently when converting to a CMYK format
(e.g. tiff32nc); see the attached screenshot.png.  The output from Acrobat Pro
9.3.3 matches Ghostscript 8 .71

The command line I'm using for testing:

  bin/gs -sDEVICE=tiff32nc -o test.tif ./altona_visual_1v2a_x3.pdf

Note that when writing to a RGB format (e.g. tiff24nc) 8.71 and head match each
other (and neither matches Acrobat).
