Well, that's a fair point, but the same happens in contrib/xml2 (if you
have a setup that doesn't need a special -I switch, or you provide that
some other way), and nobody has ever complained about it.

I wouldn't have any particular objection to that (although I think it's
supposed to be += here). I don't see that any of the other changes
Kaigai proposed are helpful, though.

Hmm. I think it's just that way to make the code look parallel for both
libraries. But I can see potential value in making -lxml2 unconditional
--- as you say, that would result in a link failure instead of a
silently broken library.
