And since the kernel uses the same set of header files for 32-bit and 64-bit versions of each architecture, I wonder whether that would make sense. Maybe the right way to do this is: - linux-libc-dev (multiarch: same) becomes a metapackage depending on linux-libc-dev-$SRCARCH - linux-libc-dev-$SRCARCH (not multiarch) provides headers for all architectures built from kernel $SRCARCH, with symlinks Ben.
