// Emit an initialization function that other TUs can call, with guard variable.

// FIXME: Mangle non-exported symbols so they don't collide with
// non-exported symbols from other modules?

// FIXME: Formally-internal-linkage symbols that are used from an exported
// symbol need a mangled name and external linkage.

// FIXME: const-qualified variables don't have implicit internal linkage when owned by a module.
