/*
 * In gcc, "extern inline" ensures that the copy in the header is never
 * turned into a separate function.  This prevents us from having multiple
 * non-inline copies.  However, we still need to provide a non-inline
 * version in the library for the benefit of applications that include our
 * headers and are built with optimizations disabled.  Either that, or use
 * the "always_inline" gcc attribute to ensure that the non-inline version
 * is never needed.
