For those of you who haven't noticed, I'm planning to commit a major change to the Makefile rules tomorrow evening (Tuesday) if there are no complaints about it between now and then.
This needs testing on Darwin. I've heard back from Linux on many platforms and even FreeBSD, which is fantastic, but I'm told that lots of LLVMers are running Darwin and I haven't heard a peep from them.
Or from you, if you're running Darwin. Hint hint!

Please hold off until someone who's running Darwin checks this.

I think that his (reasonable) message is that someone on darwin should check before he commits it tomorrow

I didn't mean to imply that it wasn't unreasonable. But that we should wait to make sure that someone tests it before then.

It seems to work fine on a variety of linux systems (mostly debian
variants on x86-32, x86-64, alpha, arm and ppc).
