The Pixma backend is running with and without this patch on my 64-bit
Ubuntu 12.04. I have no problems with any linux kernel (tested with
kernel version 3.2.0 and 3.8.0) without this patch.

'cause my ppa is affected, I would like to have an official patch for
this issue.

Somebody who is involved in coding scanimage should tell something about
this. I have no idea about the usage/need of the optind parameter in the
getopt library.

Cheers,
