The patch on the bug report does not enable JBIG support unless 
--enable-jbig is used.  I don't have any preference whether it remains 
like this or if it is changed to autodetect.

For those who may wish to use JBIG-KIT outside of the GPL, I do believe 
that Markus offers other licensing privately, but my understanding is 
that the licensing will not offer any patent indemnification.

Markus seems to have done a deliberate and thorough analysis of the 
patent situation here:

  http://www.cl.cam.ac.uk/~mgk25/jbigkit/patents.html

As I am not a patent lawyer I can't really offer any more comments on 
the patent issue than that.

Thanks,

Lee.
