This is false, as acknowledged by the C++/CEDET developer himself and
easily testable with a few lines of code.

We don't need the backend, but we need all the other big parts. In the
case of Clang, that's probably more than 70% of its source code (the
backend is provided by LLVM, which is a segregated code base.)
