http://trac.xapian.org/ticket/191 makes me think the combination only
happens at compile time, so including unused source would be OK.
I was under the impression that the FSF thinks that if it's illegal to
link a program with GPL software and distribute that, it's also illegal if you
just distribute the other program and have the user do the link.
This is the same situation, and therefore would be a GPL violation.
(And I was also under the impression that Debian follows the wishes of the
copyright holder, so it doesn't matter if this argument has any legal merit,
just that the FSF makes it.)
