Hello Debian PhotoTools Maintainers,

Upgrading sid fails with

Cheers,

Thanks.  Something apparently started to set the CC environment
variable, and it leaks into the comments in the udev rules file.
I'll try to come up with a workaround.

Dear Maintainer,

I just wanted to confirm that this also happens in the package for amd64
architecture (as expected, but added for completeness).
