The sample file needs non-standard definition of customcolorimage 
that is included only when it is not provided by the environment.

For this file to work, one needs to un-define TN5044 operators 
with -dNO_TN5044 option.

It is possible to fix the file with idiom recognition but the fix
will have some run-time cost in all cases. All recent Adobe products
bind procedures in place and discard the value returned by operator bind.
So no direct idiom recognition is possible.

However, the procedure that conditionally defines TN5044 operators
can be modified by an IdiomSet resource.
  /IMndef { 1 index where { pop pop pop } { def } ifelse } bdef
The redefined IMndef can, in turn. look into it's operands
and handle PageMaker 6.5 case specially.

I'm closing the bug as WORKS because the sample file works as designed.
The file paints wrong picture in the CMYK environment that provides TN5044
operators such as Ghostscript or Distiller. Ghostscript already has an option
to work around the bug.
