I'm not able to repeat this with the versions of gcc I have installed, and
from reading the gcc docs it seems I'm doing the right thing.
Here is the code:
// The special "extern inline" behaviour is now only supported by gcc
// when _GNUC_GNU_INLINE__ is defined, and you have to use
// __attribute__((gnu_inline)). So when we don't have this, we use
// ordinary static inline.
//
#if defined(__GNUC_GNU_INLINE__)
# if defined(KEEP_INLINES)
# define EXTERN_INLINE inline
# else
# define EXTERN_INLINE extern inline __attribute__((gnu_inline))
# endif
#else
# if defined(KEEP_INLINES)
# define EXTERN_INLINE
# else
# define EXTERN_INLINE INLINE_HEADER
# endif
#endif
So we only use the attribute gnu_inline when __GNUC_GNU_INLINE__ is
defined, which according to the gcc docs is correct.
Can someone with a Mac figure out what's going wrong here, and what test we
should use?
Cheers,
Simon
