- The whole UN*X world now uses ELF.  There's no point supporting

- C++ demangling is fine.  This entry comes from 1998, who knows what it

  architectures.  Until someone actually tries to port to non-Linux
  OS, we are unlikely to know what's missing in that area.
- The ARGTYPE_STRING stuff can be now emulated by using
    string(array(char, N))
- Dependency tracking is done by autotools
