No, I don't believe there is a standard mangling scheme.  In light of this,
I've put together a portable name mangler.  Problem is, it's rather slow,
and it's only as good as your name demangler.  (Sun's 2.0 demangler has
problems with static members, for example). It works by generating dummy
class declarations in /tmp, running your compiler, then filtering the
resultant symbol tables.  But if you don't use it with every build, it's
alright.  Anyone needing such a beast, drop me a note -- if there's enough
interest, I'll post.
