Do you? Can you enumerate on which platforms every symbol starts with
a `_'?

I think the only portable solution is to define wrappers with "C"
linkage for interfacing with the library. One such wrapper could be
used to access containers of Functors or pointers to member functions
with "C" linkage, and use them as starting points for searching C++
methods in the library.
Other than that, you might use the mangling/unmangling functions that
have been recently integrated into libiberty (have they?) to get
symbol names, but this will be restricted to GNU C++.
