Should it be marked with __attribute__((weak))?

...
weak
        The weak attribute causes the declaration to be emitted as a
        weak symbol rather than a global. This is primarily useful in
        defining library functions which can be overridden in user code,
        though it can also be used with non-function declarations. Weak
        symbols are supported for ELF targets, and also for a.out
        targets when using the GNU assembler and linker.
        
Ian.
