This patch addresses the newly introduced nullptr. Paul, I would especially value your comments on this patch, given your experience in portability issues. Regardless of taste issues (I can understand that YY_NULL looks disgraceful), I am explicitly expecting NULL to be defined for C, but if you think it's safer to define YY_NULL to ((void*) 0), please just say so (I'd like to avoid that, since I've been told many times that NULL needs not be 0, but I have just never seen that, and given the idiom "if (cp)", I really wonder if it does exist).
Not pushed, but it's in next now. Will be pushed in 2.5.1, and merged in master.
