[boost] [wave] ifndef/ifdef callbacks

Hi,

I see that there are some hooks for appending callbacks for certain
situations in the preprocessing. I think this is great. But, I would
like to know if it is possible for the user to know when the
preprocessor is evaluating an preprocessor conditional, and to know
what the condition is. And to fork the preprocessing to when the
condition is met and when not.

Thanks,
