If this is really a concern, then I would strongly encourage making symbol
versioning part of the ABI for this library (on systems that support symbol
versioning) sooner rather than later, so that a future ABI change that
*doesn't* have a good backwards-compatible workaround doesn't become the End
Of The World. :)
