Duncan,
    Also note that under darwin10, on a EMT64-capable hardware, I get...

./TargetInfo -t
x86_64-apple-darwin10.5.0

./TargetInfo -a
x86_64

./TargetInfo -p
x86

So it appears that TargetInfo needs to be called with -a and not -p on darwin10.
How can I effect this change in the dragonegg 2.9 sources?
