The package llvm-3.0-source includes tarball /usr/src/llvm-3.0/llvm-3.0.tar.xz. This tarball seems to include original llvm sources without Debian patches. clang-3.0 uses that tarball to build itself, obviously without Debian patches. Should llvm source package include *patched* sources? Or, at least, include debian-dir just like gcc-X.Y-source does?
