I'd go farther: llvm-gcc is quite dead now.

Chris,
  At the risk of hijacking the thread, are there any plans to make
-traditional-cpp
in clang completely emulate the behavior in llvm-gcc such that imake can be
built
with it (https://bugs.freedesktop.org/show_bug.cgi?id=45509). This will be an
issue
on darwin since llvm-gcc disappears after Xcode 4.6). Hopefully this can be
resolved
before that happens.

No plans that I'm aware of, but cfe-dev would be a better place to ask about
that.  -traditional-cpp is emulating pre-ansi c preprocessor behavior which is
*over* 20 years old by now.  It would be much better to work with the imake
folks to fix their code.
