__cxa_demangle should only be defined as part of libsupc++.

.. aaah but without the advantages I mentioned in my first post. The two
demanglers are designed very differently, for different purposes. I see
no reason we can't have two.

Look, all I'm asking here is you try it. If things turn into a mess
(which I doubt), or another __cxa_demangle implementation can match
functionality, I'll revisit this issue. This seems sane. Until then, I
consider this issue closed, and thank you very much for your valued

... because they mostly fail. There are ~30 FAILs, and ~9 cores. 

The regression tests come mostly from GNATS. These PR's have been around
for months, close to and over a year in some cases, without any
movement. Perhaps you could take a look at them?
