Slap a _Z on that thing and we could demangle it automatically.  The
problems with doing so are that the demangling routines are linked in
when they otherwise wouldn't be (so goes the argument, but I haven't
verified it myself).

Personally, I feel __cxa_demangler should just be present, full stop.
