To allow for non gcc compilers, I think I should in fact say
#if defined(__GNUC__) && !defined(__GNUC_STDC_INLINE__)
#define ELIDABLE_INLINE extern inline
#else
#define ELIDABLE_INLINE inline
#endif
... i.e., if using gcc without the new behaviour, use the old 'extern inline'
definition, otherwise we're either not using gcc or using gcc with the new
behaviour, so just use 'inline', which will work if we're gcc, and is just
the-best-we-can-do-and-hope-it-works for non-gcc compilers (to which 'extern
inline' means either nothing at all, or means "emit the function body as per
c99". Does that look sensible to you?
