[cfe-dev] How to demangle _ZN3foocvPT_I3barEEv?

That depends on the host platform. OSX puts an underscore before every
symbol, Linux doesn't (and Windows does something completely different
for C++).

Incidentally, my c++filt doesn't reproduce Marshall's findings either:

$ c++filt -n _ZN3foocvPT_I3barEEv
_ZN3foocvPT_I3barEEv

I couldn't make it fit anywhere in the specification either, but I'm
not an expert there.

Cheers.
