Hmm. I must admit that I still don't like this a lot. BSD is free software, we shouldn't have to put ugly workarounds in place for it, and this workaround does have some ugliness to it. Here's a radically different idea: get them to fix/improve their make. What do you think about this? If you like it, would you be willing to write a PR and/or patch? (I could otherwise try, but I'm not sure I have time for a patch.) Thanks, Ralf
