That's near impossible, as long as every C++ compiler can implement a different object model.
I don't mean to have it before someone writes a new compiler, but to interface with VC, GCC and obviously CG's own compilers.

"You" is me or CG? I didn't know that can be done now. If you mean that CG could write it for CB, it wouldn't be enough, because popular projects are mostly compiled with other compilers.

Name mangling also is specific to a compiler, and therefore incompatible.
At least GCC is open source so the algorithms for NM must be public. Also IIRC Borland had a broad deal with Microsoft that provides access to much technical specifications. Add CB to the list. With something like that, Delphi would be more compatible with C++ than C++ compilers themselves :-)
Most compatible is everthing that goes into an 'extern "C" {...}' section, for which unmangled names are created.
Unfortunately there are a lot of interesting code to interface with that is not there. Mozilla and Qt/KDE are good examples.
