Oh, and another benefit is that you can do runtime checks that the constants
exist. For example in IO-Tty I do

#ifdef B110
        newCONSTSUB(stash,"B110", newSViv(B110));
#else
        av_push(export_fail, newSVpv("B110",4));
#endif

So that the import of B110 will fail if it does not exist.

But all of this requires entering long-hand. I think the original
question was to get xsubpp to help out a bit, which I think would
be a good idea.
