Building any configuration with 'make W=1' produces a warning:

When also passing -Werror, this prevents us from building any other files. Nobody ever calls the function, but we can't make it 'static' either since we want the compiler output.
Calling it 'main' instead however avoids the warning, because gcc does not insist on having a declaration for main.
I think marking the function as static __used should do the trick and would be less confusing.
