Kaffe runs on *lots* of architectures and operating systems.. if this change means it stops working under FreeBSD then you're saying that this coincidence must be true for all those other systems, which is unlikely.. In any case, I don't understand this issue well enough but will forward the concern to the kaffe mailing list..
