     What do you mean by worked well? Since chip a GL845, it won't work 
with GL847 code.

     In order to test a newly compiled version, you can run it with the 
attached script (edit it to adapt it for the exact location of sane 
sources on your PC).
The debugging output (preview.pnm and preview.log) will help the 
development and fixes of the backend part for GL846.
