--- Comment #3 from Adam D. Ruppe <destructionator at gmail.com> ---
When is this actually useful? The case of the windows bindings' helper
functions is already solved by a linker.

If you try to separate compile anything with this pragma two things that depend
on it in a diamond shape, you're liable to get duplicate symbols. Easy to solve
with -i, but to clear how it would be solved with this pragma.
