OK, I put something like this in the bitkeeper tree now (and a 0.98
release should be forthcoming soon; hopefully today or tomorrow).
What I added is:

#define UNW_VERSION_MAJOR       0
#define UNW_VERSION_MINOR       98
#define UNW_VERSION_EXTRA       -alpha

#define UNW_VERSION_CODE(maj,min)       (((maj) << 16) | (min))
#define UNW_VERSION     UNW_VERSION_CODE(UNW_VERSION_MAJOR, UNW_VERSION_MINOR)

So, in theory, you can do things like:

#if (UNW_VERSION < UNW_VERSION_CODE(0, 98))
  ...
#endif

If this isn't what you had in mind, please let me know asap.
