Hmm. I'm pretty sure that I've run into this problem, but I concluded
that I should use either "static inline" or "extern" and didn't think
any more of it. I'm not sure that I like the idea of just ignoring the
warnings, for fear that the compiler might not actually remove the
code for the unused functions from the resulting binary. But I'm not
an expert in this area either, so maybe I'm wrong.
