I can certainly do it this way for now, but if we could do away with the tests completely, that would be cleaner.
Agreed, though, I don't believe the test is superfluous.
You still haven't answered my question wrt. Darwin 8 vs. 64-bit on
PowerPC.  Perhaps we can do away with DARWIN_LIBSYSTEM_HAS_UNWIND
completely?
To quote my previous email:

This means that I can't say for sure that is is unneeded. There was 64-bit support on darwin 8 as I recall.

It was working last time I checked (around 3-ish months ago)...
