I think that the argument from C library developers will be that the C++
modules problem is a C++ problem, not a C problem or their library
problem. And I would agree with their argument. There are libraries that
don't even bother adding `extern "C"` to their headers, I don't expect
them to make an extra effort to add a conditional compilation macro to
wrap `static`.

Bottom line is C compatibility is a very important use case for C++, so
C++ should remain as compatible with C as possible. If any C++ features
come into conflict with this compatibility, these features should adapt.
