Technically there's a requirement that external definitions be
provided.  Applications that break if you don't are pretty rare, but
why not do it right by providing some wrappers or symbol aliases in
the library?  Nothing precludes you from also defining a non-static
inline function in the header file (but note that you may need an ifdef
to handle the differences between GNU and C99 inlines.)
