Yeah, I think this is hopeless (or at least not worth the cost) without
compiler support --- I was just idly wondering if newer gcc's might have
such an option.
The case at hand is actually somewhat improbable, because it requires
having a header file that exports a variable but not any of the file's
functions. So maybe it's not worth worrying about anyway.
