Ack, I didn't read the original request closely enough, sorry :(.

Yes, you'd need to interact with C/C++, although you might be able to
use Swig to generate Java bindings... but that definitely doesn't fit
the original request.

In looking at LLVM a bit more closely, although both the FAQ and the
features page mention full C++ support, the Clang C++ page doesn't:
http://clang.llvm.org/cxx_status.html.  I'd guess, therefore, that
llvm-gcc is a different front end from Clang, which could complicate
matters.

One note on David Wigg's C++ grammar, it seemed well documented
although, IIRC, it used a slightly patched version of ANTLR or its
runtime which makes it a bit more difficult to use than would be
typical.
