This compilation error may be a side effect of my Cairo/Cairomm update.
However, I'm not sure how to handle it.  Other distros consider libpng
overzealous and simply turn the error into a warning:

  http://lists.ibiblio.org/pipermail/sm-commit/2008-December/020813.html
  https://bugs.launchpad.net/ubuntu/+source/libpng/+bug/218409

I'd happily do that but:

  $ nix-store -q --referrers /nix/store/91ms4aqkxnav6c0yzdsq9v90ql8wriy5-libpng-1.2.29/ |wc -l
  101

Should I just temporarily downgrade Cairo{,mm}?  Other ideas?

Thanks,
Ludo'.
