Hi Bart,

this is how I intend to use the versioning:

#ifndef CLICK_MAKE_VERSION_CODE
# define CLICK_MAKE_VERSION_CODE(a,b,c) (((a)<<16) | ((b)<<8) | (c))
#endif
#if CLICK_VERSION_CODE >= CLICK_MAKE_VERSION_CODE(1, 6, 9)
/* new annotation API */
# ifndef HAVE_INT64_IS_LONG
#  define FLOW_INFO_ANNO(p)   ((p)->anno_u32(4))
#  define SET_FLOW_INFO_ANNO(p, v)   ((p)->set_anno_u32(4, (v)))
# else
#  define FLOW_INFO_ANNO(p)   ((p)->anno_u64(4))
#  define SET_FLOW_INFO_ANNO(p, v)   ((p)->set_anno_u64(4, (v)))
# endif
#else
/* old annotation API */
# ifndef HAVE_INT64_IS_LONG
#  define FLOW_INFO_ANNO(p)   ((p)->user_anno_u32(4))
#  define SET_FLOW_INFO_ANNO(p, v)   ((p)->set_user_anno_u32(4, (v)))
# else
#  define FLOW_INFO_ANNO(p)   ((((uint64_t) (p)->user_anno_u32(4)) <<
32) | ((uint64_t) (p)->user_anno_u32(5)))
#  define SET_FLOW_INFO_ANNO(p, v)   do { (p)->set_user_anno_u32(4,
(uint32_t) (v >> 32)); (p)->set_user_anno_u32(5, (uint32_t) (v &
0xffffffff)); } while (0)
# endif
#endif

fundamentally I need FLOW_INFO_ANNO and SET_FLOW_INFO_ANNO to just work.
cheers
