pdf with gray shadings

Hi, 
GhostScript 9.00 generates shadings which seems too dark, when converting pdf
to eps (using epswrite)on AIX systems.
When using GhostScript 9.00 on Windows systems, the layout is fine, as
expected.

Differences can be seen in the output eps files:

Windows uses "setgray" (for example: "239 G")
AIX uses "setrgbcolor" (for example: "143 149 140 rG")


GhostScript was called in Windows like:
  gswin32c -sDEVICE=epswrite -r600 -sOutputFile=leselinie.win.eps leselinie.pdf



GhostScript was called in AIX like:
  ./gs -sDEVICE=epswrite -r600 -sOutputFile=leselinie.aix.eps leselinie.pdf



I will attach the files leselinie.pdf, leselinie.win.eps, leselinie.aix.eps 
in order to reproduce the problem.


Kind regards.

Reiner Saalfrank
