Or close to the bottom, at least.

Personally, I'd like to work towards a day when we can use C++ as part of
the development toolchain.  Yes, it will involve a larger "bootstrap" loop,
but it would only have to be done /once/.

Anyhow.

Rewriting Carlo's demangler to not use C++ can be politely described
as non-trivial.  It's not just a matter of changing the code to
use, say, libiberty's dyn_string instead of std::string, or using
obstack/hashtab/some-expandable-container instead of std::vector.
The design itself would have to change, which would mean, effectively,
that we'd no longer be using Carlo's demangler.
