Marking them "M-A: same" is not going to resolve these conflicts,
because libc0.1-dev and libc6-dev still belong to different package
sets, and with --force-overwrite you can install libc0.1-dev along
libc6-dev already.

Renaming seems to be the best long-term solution to me, but using
conflicts is probably safer for wheezy. For instance,
kfreebsd-kernel-headers:kfreebsd-i386 contains files clashing with both
libc6:i386 and linux-libc-dev:i386:
