GordonGR [1] filed a deletion request for lib32-libraw1394 [2]:

Apparently the package was moved to [multilib] but wasn't deleted from the AUR. I emailed the [multilib] maintainer about it, but they ignored me. Also, I must say that informing an AUR maintainer that you move his package to [multilib] is a good common curtesy that should be followed. Thank you.
