I have only given up on using GCC. I have not given up on improving the
C++ parser, but I will do it outside Emacs, using libtooling and
libclang.

The crucial difference is that I could not have done this on my own, but
that I would have needed lots of help from the GCC project, most
importantly the willingness to actively support tooling based on GCC,
which in the end means opening up the compiler further. I'm pretty sure
that eventually I would have needed changes upstream, either to make my
life easier, or to retrieve information that isn't available in the
AST. Even if RMS finally decides to tolerate an AST export, it is clear
that he won't approve of the general direction that is needed to make
GCC a contender in the tooling area.
